Answer:

c. beards grow thicker and their voices become slightly deeper and richer

Explanation:

Early adulthood scientifically lasts from age 20 to age 39, so, while you may be thinking puberty (hair growth, etc) it is more subtle changes such as the fact that the voice 'become slightly deeper and richer' . Both males and females continue to put on more weight (hormonal, not dietary!). Hope this helps! :)

Answer:

Diffusion is a passive process involving the movement of molecules from a region of a higher concentration to one of a lower concentration (the term passive means that the process does not require an input of energy to take place).  

Diffusion can occur across partialy permeable membranes, such as those surrounding cells. Therefore, diffusion is involved in the movement of important molecules into and out of cells. It is important for the uptake of substances needed by cells, and also the removal of waste products produced by the cells.

In animals:

Respiration - Oxygen and glucose react to form carbon dioxide and water along with ATP (a source of energy) in the process of aerobic respiration. Therefore, oxygen and glucose must be taken up by the cell, and typically the concentration of these molecules outside the cell is greater than inside. Therefore, the overall net movement of these molecules will be down the concentration gradient, and they will move into the cell via diffusion. Similarly, the carbon dioxide produced is a waste product and moves out of the cell, again via diffusion down its concentration gradient.

In Plants:

Mineral uptake - Useful minerals and ions need to be taken up from soil into plants via root hair cells. These cells are adapted (through a large surface area and large number) to maximise the rate of diffusion. Therefore, the useful molecules in the soil move down a concentration gradient and into the roots to be taken up by the plant. Many molecules found in the soil are essential for the growth and survival of plants, making diffusion a very important process.

Diffusion is important in plants and animals because it ensures that the metabolic processes in both types of cells / organisms can develop normally.

Diffusion can be defined as the spontaneous movement of particles as a consequence of their thermal energy from areas of high concentration to areas of low concentration.  

Plant and animal cells are similar, plant cells have a rigid cellulose wall, which provides protection, without preventing the diffusion of water and ions from the environment to the plasma membrane.

For example, photosynthesis in plants depends on the diffusion of water and CO2; likewise, that of water vapor by perspiration is a diffusive process.

The absorption of minerals from the soil solution by the roots is partly dependent on diffusion; likewise, all chemical processes, including those catalyzed by enzymes, depend on collisions produced by diffusing molecules.

Animal cells also undergo a series of changes when subjected to different conditions of water content.

For example, the movement of water through the plasma membrane determines the cell volume.

The regulation of this volume is very important since animal cells cannot withstand the entry of large amounts of water due to the fact that they enter a state of turgor.

The regulation of the movement of water under these conditions is called osmosis, a special kind of diffusion that depends on the relative concentration of water molecules.

Therefore, we can conclude that diffusion is important in plants and animals because it ensures that the metabolic processes in both types of cells / organisms can develop normally.

Answer:

Please find the description of the role of fermentation in the production of ATP and NAD+ levels below.

Explanation:

Fermentation is a form of anaerobic respiration in which glucose is broken down in the absence of oxygen to produce carbon dioxide and alcohol or lactic acid depending on which type of fermentation it is.

Fermentation process makes use of the electron carrier, NADH, mad oxidizes it back to NAD+. This electron acceptor molecule is strictly required in the glycolysis process. Hence, fermentation helps convert NADH to NAD+ needed by glycolysis for the production of few ATP molecules. In summary, fermentation may not directly synthesize ATP but it helps produce the molecule (NAD+) needed to synthesize it.

Answer:

It depends on the salt concentration inside the cell.

Explanation:

The movement of water through a semi-permeable membrane with different salt concentrations depends on the amount of water and salt concentration in the cell. If the cell has more salt concentration so no more salt moves inside the cell but moves outside the cell while on the other hand, if the cell has low amount of salt than the outer environment then the salt moves inside the cell until its concentration are equal.

Answer:

c) tubes 2, 3, and 4 only

Explanation:

Cellular respiration is a metabolic process in which cells of living organisms break down organic molecules to synthesize or release energy in form of ATP. Because all cells require or need energy (ATP) for their functioning, cellular respiration is carried out by ALL LIVING ORGANISMS.

According to this question involving four test tubes that contain the following:

- Tube 1 contains water only.

- Tube 2 contains a live snail.

- Tube 3 contains a live green water plant.

- Tube 4 contains both a live green water plant and a live snail.

Cellular respiration will be carried out in the test tube that contains any living organisms. These test tubes are test tubes 2, 3 and 4 as they contain live green plants and snail.

Answer:

C. BbSs

Explanation:

The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.

This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.

So, the genotype must be C, BbSs

The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.

The parent's genotype will then be BbSs.

The genotype of both parents have to be heterozygous as a result of the

presence of its forms in the B and S traits. There is the presence of the

dominant (B,S) and recessive traits (bs).

The genotypes of the parent will however have both traits in them which

translates to the option C) BbSs being the most appropriate.
