Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
Answer:
When the predators' population is increased, there will be a high risk to the cricket frog from these predators as they may start attacking them rigorously and ultimately lead to a sharp decline in their population.
Answer:
two domains is the answer
<h2>
Answer:</h2>
There two features which facilitates bird <u>to fly are presence of light and smooth feathers and light bones</u>.
<h2>
Explanation:</h2>
Birds are the only living creatures which has the ability to migrate from one place to another through flying. There are many physical features present in their body which facilitates them in flying.
<u>Among the two features and their role in flying are as follows: </u>
-
Light and smooth feathers: Wings are the organ which is involved in flying. It is composed of feathers which are very colorful and are light in weight and smooth in its appearance. This apart from reducing the body weight helps the bird to reduce the force and drag during flying.
- Light bones: The skeletal system of the birds is composed of light bone which are primarily hollow with air sacs. This accounts for less body weight while flying.
Answer:
Glycogen. (Ans. C)
Explanation:
Glycogen is known as the storage form of glucose in animal cells. It a polysaccharide of glucose which is multi-functional and serves as an energy form storage in animals. Liver cells primarily stored glycogen, some glycogen also stored in muscle cells for immediate use if needed.
Glycogen molecule composed of many glucose molecules that are linked together with the help of the alpha acetal group. To create energy currency (adenosine triphosphate) glucose is the primary source used by every cell.
