Water is important for maintaining good health because it is involved in many of the body's functions. Dehydration can occur when the body does not get enough water.

Here are some of the ways in which water helps to keep us healthy:

Regulates body temperature: By transferring heat away from the body's center and evaporating off the skin, water helps to control body temperature.

Moistens tissues: Water helps to keep tissues wet, including those in the mouth, nose, eyes, and throat. By doing this, you can keep them from drying out and being itchy.

Protects organs and tissues: By cushioning organs and tissues and keeping them from rubbing against one another, water helps to protect them.

Carries nutrients and oxygen to cells: Water helps the body's cells transport nutrients and oxygen by carrying these substances to them.

Removes waste products: Urination, sweating, and bowel motions are ways in which water aids in the removal of waste from the body.

Lubricates joints: Water aids in lubricating joints, which helps to lessen friction and discomfort.

A because this is where the pollen is. so when bugs stand on here they take the pollen somewhere else and by accident they spread it. I hope this helps :}

Flowers reproduce sexually through pollination. Flowers have male stamens and female pistils. The component of the stamen known as the anther is the part that houses the pollen grains. Therefore, option (A) is correct.

Pollination is the process that allows flowering plants to carry out their sexual reproduction.

In flowering plants, sexual reproduction requires the development of distinct male and female gametophytes, which are responsible for the production of gametes. Pollen grains, which are male gametophytes, are produced by the anthers of the plant. The grains of pollen adhere to the stigma at the top of a carpel, which is the part of the reproductive structure that contains the female gametophytes (ovules).

The correct answer is: b) directional selection

Directional selection is a type of natural selection in which an extreme phenotype is favored over other phenotypes. In this case, phenotype of large crickets will be favored, because they cannot be eaten by lizards. Large crickets are advantageous in surviving and reproduction. This will cause the allele frequency to shift over time in the direction of that large size phenotype.

Answer:

b) Directional selection  

Explanation:

Direction selection is the phenomenon in which a population’s genetic variance changes with respect to environmental changes to select a new phenotype. In this case, the size of cricket, the food source acts as the selection factor for the phenotype, the size of the lizard’s mouth.  

In order to accommodate the food source, a single phenotype of mouth size changes and the respective allele is favoured. Correspondingly, the allele frequency will shift unilaterally in one direction only.  

The increased frequency of the particular allele ensures a higher survival rate of the lizard. The population evolves towards the favoured phenotype.

Hi there!

The major structure for a neuron is,

D). Axon, cell body, and dendrites.

Hope this helped!~

The major structures of a neuron are the cell body, dendrites, and axon. The cell body contains the nucleus, dendrites extend from the cell body to receive signals, and the axon transmits signals away from the cell body. The correct answer is D. Axon, cell body, dendrites.

The major structures of a neuron include the cell body, dendrites, and axon. The cell body, sometimes referred to as the soma, contains the nucleus and other essential organelles for the neuron's function. Dendrites are extensions that branch off from the cell body receiving signals from other neurons, while the axon is a longer extension that carries nerve impulses away from the cell body to other neurons or muscles. At the end of the axon, axon terminals, or synaptic boutons, allow communication with other cells. The correct answer to the student's question, identifying the major structures for a neuron, would therefore be D. Axon, cell body, and dendrites.

because a glucose molecule is to large to pass through a cell membrane cells assist glucose diffusion through facilitated diffusion and two types of active transport.

The process of facilitated diffusion is most likely used to transport glucose into muscle cells as it does not use energy and is helped along by specific carrier proteins in the cell membrane.

The process most likely used to transport glucose into a muscle cell is facilitated diffusion. This process involves specific carrier proteins in the cell membrane that bind to glucose to allow its passage into the cell. These proteins are used because, even though glucose is small in nature, the polar hydroxyl groups (-OH) attached to the glucose molecule prevent it from easily passing through the nonpolar lipid bilayer of the cell membrane.

The process does not require energy as facilitated diffusion is a type of passive transport, moving from a higher concentration (outside the cell) to a lower concentration (inside the cell). Thus, glucose can enter most body tissues, including muscle cells, without the use of energy.

To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper wire.

Answer: The correct answer is "electromotive force".

Explanation:

If the battery is connected to the conductor which makes the flow of the electric charge. Battery forces the charges to flow. The rate of flow of charges constitutes the electric current.

The electromotive force is required for an electric charge to flow through a wire. Here, it is provided by the battery.

Battery allows the flow of electrons between cathode and anode. The cathode is at lower potential and the anode is at higher potential. The charges flow from lower potential to the higher potential.

Therefore, battery is required which provides electromotive force for an electric charges to flow through a wire.

he given isotope is bismuth 208. The atomic number of bismuth is 83 therefore the number of protons is 83. When bismuth loses one proton it results in the element lead with only 82 protons. The mass number is the total number of protons and the total number of neutrons. So on losing proton  bismuth becomes lead and on gaining neutron the mass number does not change and remains as 208. Therefore it reduces to lead but the mass number remains the same.

Therefore the answer is B. Bismuth on losing one proton and on gaining a neutron it becomes Lead 208.

The carbon cycle explains how carbon travels between the atmosphere, biosphere, hydrosphere, and geosphere. This complex cycle involves rapid carbon exchanges amongst living organisms and slow, long-term exchanges via geological processes. The increased use of fossil fuels has also contributed to increases in atmospheric carbon dioxide, impacting climate change.

The carbon cycle describes how carbon moves through the atmosphere, biosphere, hydrosphere, and geosphere. Carbon is the fourth most abundant element in living organisms and plays a crucial role in the structure of macromolecules. The carbon cycle is a complex process that can be studied as two interconnected sub-cycles: one dealing with the rapid carbon exchange among living organisms and the other dealing with the slow, long-term cycling of carbon through geologic processes.

Carbon is stored in carbon reservoirs which includes the atmosphere, bodies of liquid water (mostly oceans), ocean sediment, soil, land sediments (including fossil fuels), and the Earth's interior. Living organisms are also part of the carbon cycle through the exchange of carbon dioxide between autotrophs (which need carbon for photosynthesis) and heterotrophs (which release carbon dioxide).

Fossil fuels, which are a form of stored carbon, have been increasingly used since the Industrial Revolution, resulting in an increase in atmospheric carbon dioxide, a factor associated with climate change.

Cellular respiration consists of glycolysis, the Krebs Cycle, and the electron transport chain. These stages work together to convert glucose and other organic molecules into ATP, which cells use as a source of energy for various biochemical processes.

1.Glycolysis: Glycolysis is the first stage of cellular respiration, and it takes place in the cytoplasm of the cell. During glycolysis, a single molecule of glucose is broken down into two molecules of pyruvate.

This process doesn't require oxygen and is therefore considered anaerobic. It yields a small amount of ATP and some molecules of NADH (nicotinamide adenine dinucleotide), which carry high-energy electrons.

2. Krebs Cycle (Citric Acid Cycle): The Krebs Cycle, also known as the citric acid cycle or TCA cycle, occurs in the mitochondria. In this cycle, the two molecules of pyruvate generated in glycolysis are further broken down. This stage is aerobic, meaning it requires oxygen.

For each pyruvate, it produces three molecules of NADH, one molecule of FADH2 (flavin adenine dinucleotide), one molecule of ATP, and carbon dioxide as waste.

3. Electron Transport Chain (ETC): The final stage of cellular respiration is the electron transport chain, which also takes place in the mitochondria. The high-energy electrons carried by NADH and FADH2 from glycolysis and the Krebs Cycle are passed through a series of protein complexes, creating a flow of protons (H+) across the inner mitochondrial membrane. This proton gradient generates a strong electrochemical gradient, and the flow of protons back through the ATP synthase enzyme results in the production of a significant amount of ATP.
