Which evidence supports the endosymbiotic theory? Select all that apply. Mitochondria and chloroplasts have a separate, simpler DNA from the nucleus DNA of a eukaryotic cell. These organelles' DNA resembles the DNA of prokaryotic cells. Mitochondria and chloroplasts self-replicate by a cell division process similar to binary fission, which is the way prokaryotes divide. The way mitochondria and chloroplasts synthesize proteins within the eukaryote cell is more similar to prokaryotes than to eukaryotes. There are living examples of prokaryotes, like cyanobacteria, that share similar features with both mitochondria and chloroplasts of eukaryotic cells. Observations of prokaryotic cells engulfing other prokaryotic cells and the engulfed cells becoming the organelles have been recorded.

An uncommon and clear splendidly hued mineral is known as a gemstone. The variety frequently results from minor components inside the mineral.

Complete question as follows:

A rare form of mineral that is usually very clear and brightly colored  is known what ?

Answer:

The process that occurred in the lake is natural selection. In the presence of an external environmental influence such as the pollution, only the trouts that were fit to survive or in other words those that have the alleles that help in adapting to the new conditions live and increased in numbers. In such a case, one can say the fittest of the organisms survived and the corresponding allelic frequency in that population increased over time. The organisms carrying the other alleles died due to pollution and hence the overall frequency of alleles change.

Answer:

The correct answer is first statement.

Explanation:

The lanternfish refers to a fish that thrives in deep-water and has got its name due to the tendency to generate light. The light is produced by the small organs called photophores. Within the photophore, a chemical reaction occurs that produces light and the whole process is termed as bioluminescence. Due to less light in deeper water zones, these fishes are found there as they possess the tendency to generate their own light. These fishes are basically found in the disphotic or in the twilight zone.

Hans Selye called the body's response to stress the general adaptation syndrome (GAS). It consists of three stages: the alarm stage, resistance stage, and exhaustion stage.

Hans Selye called the body's response to stress the general adaptation syndrome (GAS). The GAS consists of three stages: the alarm stage, the resistance stage, and the exhaustion stage.

In the alarm stage, the body perceives a stressor and activates the fight-or-flight response. This leads to the release of stress hormones, increased heart rate, and heightened senses.

In the resistance stage, the body attempts to cope with the ongoing stress. It adapts to the stressor and tries to maintain physiological balance. However, the body remains on high alert and may experience symptoms of chronic stress.

In the exhaustion stage, prolonged exposure to stress overwhelms the body's resources. Physical and mental exhaustion may occur, increasing the risk of illness and disease.

The electromagnetic spectrum is the range of all the wavelengths (frequencies) of electromagnetic radiation.

A group of electromagnetic waves that travel at the speed of light and are produced by sources of the electromagnetic field is known as electromagnetic radiation.

We can only see a small portion of the electromagnetic spectrum (EM spectrum), although there are many other types of invisible light waves.

The electromagnetic spectrum (EM spectrum) has seven different wavelength types: radio, microwave, infrared, visible, ultraviolet, x-ray, and gamma.

Therefore, in the electromagnetic spectrum, gamma rays have the greatest frequencies and smallest wavelengths since radio waves have the lowest frequency and consequently the biggest wavelengths.

Answer:

( D) Genetic Drift is a correct answer

Explanation:

Allele frequency in a population depend on Genetic Drift because:

Due to Genetic Drift allele frequencies is changed within a population by the error in the sampling, It results in a large change in the populations within a short period.

Allele frequency is used to measure the relative frequency of different alleles of the particular gene in the population.

An organism is a living thing that carries out the seven life processes: order, sensitivity or response to stimuli, reproduction, growth and development, regulation, homeostasis, and energy processing. Each of these processes is fundamental to life and is demonstrated by all forms of living beings, from single-celled organisms to complex multicellular beings.

A living thing that carries out the seven life processes is typically referred to as an organism. These life processes include order, sensitivity or response to stimuli, reproduction, growth and development, regulation, homeostasis, and energy processing. All organisms, from single-celled bacteria to complex multicellular humans, exhibit these fundamental characteristics that define life.

For example, organisms maintain order by having well-organized, structured bodies and cellular systems. They show sensitivity by responding to changes in their environment. Organisms also reproduce to propagate their species, grow and develop from immature stages to mature forms and perform regulation and homeostasis to maintain a stable, internal environment. They also engage in energy processing to carry out life activities.

Going upward from the surface, it is the point where air ceases to cool with height, and becomes almost completely dry. More formally, the tropopause is the region of the atmosphere where the environmental lapse rate changes from positive, as it behaves in the troposphere, to the stratospheric negative one. Following is the exact definition used by the World Meteorological Organization:

The boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs. It is defined as the lowest level at which the lapse rate decreases to 2 °C/km or less, provided that the average lapse rate between this level and all higher levels within 2 km does not exceed 2 °C/km.[1] for example

Salt doesn't melt frogs; this is a misunderstanding relating to its effect on ice, where it lowers the freezing point. In a biological sense, salt can harm amphibians like frogs through osmosis by dehydrating their tissues. Understanding biological responses to chemical cues can be studied using controlled experiments.

Salt does not literally 'melt' frogs. The confusion might stem from the way salt can affect ice and living tissue. When salt is used on icy roads, it works by lowering the freezing point of water, causing ice to melt at lower temperatures. This is due to the salt disrupting the orderly arrangement of water molecules in ice, making it harder for water to remain solid. The salts commonly used are rock salt (NaCl) and calcium chloride (CaCl2).

In the biological context, if we consider how salt affects amphibians like frogs, the concept of osmosis is key. Frogs, being amphibians, have semi-permeable skin that allows for the passage of water and certain solutes. If a frog were to come into contact with a highly concentrated salt solution, it would lead to dehydration of its tissues due to water moving out of its cells to balance the salt concentration, which could cause harm to the frog.

Experimental Design in Biology

In biology, experiments such as the one involving salamanders described above can help us understand animal behavior in response to chemical cues. To test if frogs use chemical detection for predator avoidance, a similar setup could be used where water containing chemicals from predatory fish is introduced to a frog's environment, and the frog's behavior is observed for any changes indicating detection of the predator.

Protons and neutrons are the subatomic particles located inside the nucleus; electrons, which are the smallest and negatively charged, orbit outside the nucleus.

Protons carry a positive electric charge and, along with the neutral neutrons, they provide most of the mass of the atom. The electron, which is the smallest of the three types of subatomic particles and carries a negative charge, is found outside the nucleus. Electrons orbit the nucleus in various shells and subshells and contribute to the atom's overall size.

Both the processes takes place in mitochondria and result in producing more ATP. The correct option is B.

Mitochondria are bilayer cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).

The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).

Mitochondria convert chemical energy from food in the cell to energy usable by the host cell by using oxygen available within the cell.

The process is known as oxidative phosphorylation, and it occurs within mitochondria.

The Krebs cycle and electron transport chain processes occur in mitochondria and result in the production of more ATP.

In turn, ATP serves as the primary energy source for the majority of biochemical and physiological processes, including growth, movement, and homeostasis.

Thus, the correct option is B.

Explanation:

The question discusses the biochemical processes of the conversion of glucose into starch, fructose and glucose into sucrose, and cellulose into glucose.

The processes described involve the conversion of different types of sugar units. Firstly, the conversion of glucose units into starch occurs in plants as a means to store excess glucose produced during photosynthesis. This involves linking glucose molecules together to form a polysaccharide starch. Secondly, the conversion of fructose and glucose units to form sucrose is another common biochemical process. Sucrose is a disaccharide made by combining a glucose unit and a fructose unit. Lastly, the conversion of cellulose into glucose units represents the breakdown process where organisms, especially those living in the gut of animals, can convert cellulose back into glucose for their energy needs.
