Which best describes a recessive allele?

A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.

According to Charles Darwin in his theory of natural selection, organisms must compete for scarce resources. Only the fittest can survive. The fittest are organisms that have undergone the required genetic changes that increases their chances of survival. They pass on these genetic changes to the next generation or offspring.

When availability of food decreases, organisms begin to change genetically as they struggle for scarce resources thereby leading to variation in a population. All organisms must compete for survival. Natural selection continues to occur even today.When organisms struggle to survive, they usually mutate to increase chances of reproduction.

Therefore, A trait that does not offer members of a population a great advantage will most likely decrease in frequency in successive generations. Thus, option B is correct.

Answer:

The use of anabolic steroids can raise blood levels of testosterone well above a person's normal range. As a result, the body may try to regulate testosterone levels by shutting down its own production of testosterone. In order to prevent this, people usually use anabolics in cycles of a few weeks on and then off.

Answer:

The answer to this question is Transport would increase.

Explanation:

The transport would just increase.

In the given area-to-volume ratio, the transport would increase across the cell membrane. The correct option is B.

The surface area to volume ratio is merely the surface area divided by the volume of an entity. It calculates the surface area per unit volume of the object.

The crucial fact is that as the cell size increases, the surface to volume ratio decreases.

If the cell expands beyond a certain size, not really enough material can cross the membrane quickly enough to cater the increased cellular volume.

The surface area divided by the volume is the ratio. This suggests how much surface area is accessible in relation to the size of the cell.

The cell is very large if the surface area to volume ratio is small. If the ratio is large, the surface area exceeds the volume the cell will be small.

Thus, the correct option is B.

The correct answer is - (3) natural communities replacing each other in an orderly sequence

Explanation:

In this diagram, there is ecological succession occurred, the process of the new natural community over the older natural community in an orderly sequences.

In this case, there are change from an aquatic ecosystem to new land ecosystem by changing various biotc and abiotic factors. The ecosystem go through various changes and physical changes.

Answer:

The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.

Explanation:

In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.

In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.

Answer:

false

Explanation:

Answer: 1. 1. More mutations. 2. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Answer:

The artificial reef would decrease erosion of the coastline.

Explanation:

Artificial reefs are created in area where there is little uderwater topography or near established coral reefs to imitate or even substitute for natural coral reefs where they are absent or endangered due various factors which are mostly human in nature. The artificial serves to provide a habitat for marine organisms and ensure more biodiversity around the area by providing shelter from predation and surfaces for encrusting organisms such as corals and sponges to grow on. The growth of these lower level food chain organisms attract larger predator organisms thereby increasing the biodiversity in the area.

Artificial reefs are made from a variety of materials such as shipwrecks, construction debris, oil rigs, concrete, and any other man-made objects. Since reef structures protect shorelines against waves, artificial reefs would decrease the erosion of the coastline providing benefit to the people living along the coastline by preventing the destruction of beaches and coastal property,

Answer:

B

Explanation:

Desalination remains expensive, as it requires enormous amounts of energy. The correct answer is b) The process uses fuel that is expensive.

Saline water which is typically sea water, is artificially transformed into fresh water through a process called desalination. Reverse osmosis and distillation are the two most used desalination techniques. There are several approaches. Although each has benefits and drawbacks, they are all useful.

The issue is that it takes a lot of energy to desalinate water. When salt is dissolved in water, it forms strong chemical bonds that are challenging to break. Desalinating water may be rather expensive since both the energy and the technology required are costly.

Desalination turns seawater into freshwater by removing the salt, however, it also has certain unfavorable effects on the ecosystem. Desalination facilities release trash and poisonous chemicals that are bad for the environment and animals. The procedure can also increase the salinity of saltwater, which has an impact on fish.

Therefore, the correct answer is b).

Explanation:

Opposites for REGULAR mDNA base pairings are T= A  and G = C, however, since it is mRNA, your base pairings change a little. G is still to C BUT Thymine (T) becomes Uracil (U) so A= U instead of A= T.  So big difference between mRNA and mDNA is that Thymine changes to Uracil and vice versa depending on how the code is being translated.
