Fishes eat very little during the winter as their metabolism slows down as their metabolism slows down.
Explanation:
Fishes are cold blooded animals and their body temperature is regulated with the change in the water temperature. When the water temperature becomes cold the fishes slow down in feeding. Fishes during winter undergoes certain changes in their body which slows down their metabolism rate.
When their metabolism slows down they will not stop feeding completely but lessen their feeding habit. During winter they also become less active. They seek pocket holes and go to that particular place and stay still. This helps them conserve energy.
Fish eat less during winter as they enter a state of reduced physiological activity, or torpor, to conserve energy due to the cold temperatures. This slows down their metabolism and digestion rate, hence the diminished need for food.
Explanation:Fish eat very little during winter due to a biological process known as torpor. In cold temperatures, fish, being cold-blooded animals, enter a state of reduced physiological activity to conserve energy. This process slows down their metabolism, including the rate of digestion, making them eat less because they don't need as much energy to maintain body functions. Despite the higher amount of dissolved oxygen and availability of food, fish don't feel the same need to eat as they do during warmer seasons because their bodies are not as active.

Which statements describe some ways that the student recorded data incorrectly on the lab report to the right?
A. The speed data should all be arranged in
increasing order.
B. No units are given for the speed of the water.
C. Millimeters are not the best unit to use for the
distance.
D. Wind speed should be in mph.
E. The student mixes units of length, using SI units for distance and customary units for depth.
The student recorded data incorrectly by omitting units for the speed of water and potentially mixing units for length and depth. Appropriate and consistent units must always accompany scientific measurements, and an understanding of both SI and customary units is necessary.
When recording data, it is essential that units are always included to avoid confusion and ensure precision in communicating the results. While there is no strict rule that speed data must be arranged in increasing order, it could help in some analyses. However, if the data does not include units for the speed of the water (statement B), then that is incorrect. The choice of millimeters as a unit for distance (statement C) depends on the desired precision and the context of the experiment; millimeters are a fine unit for short distances, but could be impractical for longer ones. Wind speed does not necessarily need to be in mph (statement D) as it depends on the regional or scientific standard; both m/s and km/h are also commonly used. Lastly, mixing SI units for distance with customary units for depth (statement E) can lead to confusion and should be avoided; consistency in the unit system is crucial unless there's a specific reason to convert between them. Furthermore, consistency is important when presenting data. It's crucial for students to understand both SI and customary units to effectively interpret and communicate scientific information, which includes being able to convert units when necessary. Therefore, the student must check their lab report to ensure that units are present, appropriate, and consistent throughout the document.

How are humans connected to photosynthesis? *Include the words: autotroph, cellular respiration, energy, photosynthesis*
Photosynthesis and cellular respiration interconnect plants and human beings.
Explanation:
Plants prepare their own food and are autotrophs. Humans depend on autotrophs both directly and indirectly for food and are heterotrophs.
Heterotrophs consume both plants and animals to get energy
Photosynthesis: reactants - sunlight, carbon dioxide and water; products – sugar, oxygen
Cellular respiration: reactants - glucose and oxygen; products – water, carbon dioxide
Carbon dioxide (end product) released due to cellular respiration by the humans enters the atmosphere and is absorbed by the plants which become a reactant in photosynthesis.
Oxygen (end product) released due to photosynthesis by plants enters the atmosphere and is inhaled by human beings and becomes a reactant in cellular respiration.

6. Telophase I
7. Prophase II
8. Telophase II
Explanation:
The phases of meiosis can be remembered using the acronym PMAT
The first stage (during Meiosis I), is called Prophase I. During this phase, the chromosomes condense and become visible and the nuclear envelope breaks down. Homlogous chromosomes pair up and crossing over occurs, meaning they exchange bits of DNA.
Next, Metaphase I occurs, in which the pairs of chromosomes move to the centre (equator) of the cell and line up long the equator.
Anaphase I then occurs, where special microtubules called spindle fibres pull the homologous chromosomes to opposite sides of the cell.
The next step is called Telophase I, in which the chromosomes gather at the poles, spindle fibres degrade, the cytoplasm divides and a new nuclear membrane forms - producing 2 daughter cells.
The cell now enters Meiosis II, the first stage of which is Prophase II. During prophase II, the chromosomes condense, the nuclear envelope breaks down again and a new spindle apparatus forms.
The next stage is Metaphase II, during which the chromosomes (now not in their homologous pairs as these have already been divided) are aligned in the centre of the cell, the equator.
The next stage is Anaphase II, in which the chromatids are pulled to opposite ends of the two daughter cells by the spindle.
The final stage is Telophase II, where 4 haploid daughter cells are formed after the reformation of the nuclear membranes, division of the cytoplasm and the chromatids uncoil.
A student claims that if the animal producing the spermatozoa has a mutation in a mitochondrial gene, the probability that any offspring will inherit the mutation is zero. Provide evidence to support claim.
Answer:
Mitochondrial DNA is inherited from the maternal side
Explanation:
Mitochondrial DNA is inherited from the maternal side (from the oocyte). The mitochondria from the sperm cell including their DNA are degrade after fertilisation.
The size of the cells that make the zygote also contribute to this. The oocyte is much larger than the sperm, containing around 100,000 mitochondria, whereas the much smaller sperm cell only contains around 100. This means even initially, there are very few paternal mitochondria compared to maternal mitochondria in the first place, effectively diluting them out.
This, coupled with the degradation of the sperm mitochondria, means that offspring will not inherit mitochondrial DNA and any mutations from their father.
Sperm or the spermatozoa is a male reproductive cell. It consists of flagella, head and body. The sperm or the male cell fertilizes with the female reproductive cell called the egg to produce offspring.
If the organism producing the spermatozoa has a modification in a mitochondrial gene, then the possibility of offspring having a mutation will be zero.
The explanation for the above statement is:
Mitochondrial gene is obtained from the maternal side that is the mother's reproductive cells (oocyte).The mitochondria of the male reproductive cell the sperm degenerate after the process of fertilization and do not take part further in the process.The abundance of female mitochondria outnumbers the mitochondria present in the sperm cells.Therefore, mitochondrial DNA transfers exclusively from the mother to the offspring.

Where do marine scientists get the ethical standards for their profession and what kind of values do they include?
Answer:
Explanation:
The ethical standard was accepted by the Society in the 2013 mid-year ballot. This Code states 17 guiding principles aimed at assisting the Society.
Some of the ethical issues include the potential for data fabrication/ falsification,
conflicts of interest, human subjects violations, working with scientific uncertainty and values conflicts in marine conservation.
Final answer:
Marine scientists acquire their ethical standards from scientific ethics, philosophical discussions, religious and environmental ethics, and community norms. These standards emphasize the minimization of harm to organisms and ecosystems, as well as unbiased research. Ethical reasoning features in education and policy to guide practitioners in morally complex situations.
Explanation:
Origins of Ethical Standards in Marine Science
Marine scientists derive their ethical standards from a variety of sources including scientific ethics, philosophical discourse, and environmental considerations. These standards aim to protect humans, animals, and ecosystems from undue harm while promoting research that is free from bias. Principles of ethics such as compassion, humility, respect, coexistence, and sustainability guide interactions with marine life, with an increasing focus on moral considerations as we learn more about marine cognition and consciousness.
Ethical dilemmas, intrinsic and extrinsic values, and the application of ethical reasoning are core components within the marine science field. This includes the management of fisheries and the conservation of rare and endangered species, where ethical assumptions can significantly influence policy and practice. Additionally, religious and environmental ethics contribute to shaping the values and norms that marine scientists may hold, especially when pondering grand questions about humanity's relationship with the ocean and its inhabitants.
To foster ethical conduct, the incorporation of ethical reasoning is advocated in curricula, major meetings, and agency operations. Emotion plays a critical role in shaping moral judgments, which is why the engagement of both hearts and minds is encouraged in ethical deliberations. This holistic approach helps marine scientists navigate complex ethical landscapes in their work.

what passes electrons in the etc
There are different electron carrier carriers in the mitochondria that helps in transferring electron in the Electron Transport Chain.
Explanation:There are different reactions like Kreb's Cycle and others going in the mitochondrial matrix. These reactions synthesize different reduced proton like NADH₂ and FADH₂. These reduced carriers then go to the inner mitochondrial membrane where there are different electron carriers - four in types namely complex 1,2, 3,and 4 respectively. NADH₂ goes to complex 1 and release the Hydrogen and gets back to NAD and FADH₂ goes to complex 2 and release Hydrogen and gets back to FAD.
The electron that is released to the complex 1 goes to complex 2 and then to Q complex. Then it goes to complex 3 and 4 respectively where the final electron is taken by the oxygen atom to produce oxide ion.

polysaccharides, such as starch, have in common?
A They are lipids made of fatty acids.
B They are proteins made of amino acids.
C They are nucleic acids made of nucleotides.
D They are carbohydrates made of simple sugars.
Explanation:
D They are carbohydrates made of simple sugars.
Both disaccharides and polysaccharides belong to the category of carbohydrates, as they are both made up of simple sugars or monosaccharides. Two monosaccharides combine to form a disaccharide, while many monosaccharides join together to make a polysaccharide. Hence, both sucrose (a disaccharide) and starch (a polysaccharide) consist of simple sugars.
Explanation:Disaccharides like sucrose and polysaccharides like starch are both classified as carbohydrates. These compounds are constructed from smaller, simpler units known as simple sugars, or monosaccharides. Disaccharides are formed when two monosaccharides combine together, whereas polysaccharides are made of a larger number of monosaccharides. Hence the correct answer to your question is D - They are carbohydrates made of simple sugars.
Examples of monosaccharides include glucose and fructose, and these can combine in different ways to form disaccharides and polysaccharides. Sucrose, for example, is made of one glucose and one fructose molecule. Starch, on the other hand, is a polysaccharide made primarily of glucose units.

Which of the following is the MOST accurate regarding the speed of light?
A) The speed of light depends on the color of light that we see.
B) The speed of light is constant in all media at all times and places.
C) The speed of light can change as it moves through different materials.
D) The speed of light is only affected by the brightness of the light.
Answer:
C
Explanation:
The speed of light can change as it moves through different materials
Option C is correct; the speed of light can change as it moves through different materials, even though it remains constant in a vacuum and is not affected by the light's color.
The most accurate statement regarding the speed of light is that it can change as it moves through different materials, making option C the correct answer. The speed of light in a vacuum, denoted as c, is a constant value of approximately 3 × 10⁸ m/s, and is one of the fundamental constants of physics. This means that regardless of the motion of the source or the observer, the speed of light in a vacuum remains the same. However, when light passes through different materials, such as air, water, or glass, its speed is affected by the refractive index of the material. For instance, light travels slower in glass than in air. While the speed is constant in a vacuum and does not depend on the frequency or wavelength of light (thus, not on the color), it does vary in materials with different refractive indices.

Which of the following accurately describes what makes a material a good conductor?
A. It must resist neutron flow.
B. It must readily accept electron flow.
C. It must readily accept neutron flow.
D. It must resist electron flow.
Answer: Option B
Explanation:
The electrical current is defined as the flow of electrons inside a material.
As more electrons can flow in a given time (for a fixed area, suppose the transversal area of a wire), more electricity is being generated.
Some materials have some resistance to the flow of electrons because they have "obstacles" that impede the free flow of the electrons, and when the electrons hit those obstacles, energy is liberated, this is why some materials heat up as a current flows throw them.
Now, you also may know that as the temperature of an object increases, also the kinetic energy of the particles inside of it, so the particles of the material will be moving a lot more, and because of this, the electrons will find more resistance to the motion.
The correct answer here is B; a good conductor must readly accept the electron flow.
Answer:
Readily accept electron flow
Explanation:
The answer is b. Readily accept electron flow. It is because electron flow is the reason for generation of electricity i.e, current is produced in the direction opposite to the electron flow. In order to behave as a good conductor, it must allow free flow of electrons through it. Hope it helps:)))

Lakes can be formed as a result of what type of weathering? Select ALL that apply.
Glacier movement over the crust
Upwelling from the water table
Formation of a terminal moraine
Trapped acidic water dissolving large amounts of limestone
Answer:
Options A and D are correct:
Glacier movement over the crustTrapped acidic water dissolving large amounts of limestoneExplanation:
Glacial lakes: It has been well reported that glacial erosion often leads to the development of lakes. When a glacier moves, it erodes the sediments which lead to the formation of depressions. In later years, these depressions are filled with water and form a lake. This is why these lakes are recognized as "glacial lakes".
Lakes formed by dissolving limestone: We know that acids can dissolve the limestone (CaCO3) very quickly. Therefore, if acidic water traps in an area where the bed-rock is made up of limestone, the water will dissolve it and form a depression. The acidic water could stay the same place forming acidic lakes or could be replaced with normal water later on due to hydrogeological processes.
