A population characterized by the largest number of people in the post-reproductive age group on a population pyramid will tend

SIZIF [17.4K]

The number post-reproductive age group will decline in number in a population pyramid.

<h3>What is a population?</h3>

A population is a group of organisms of the same same specie living in a defined area of a given habitat.

A population pyramid shows the number of organisms of age groups in a population.

The post-productive age group is characterized by individuals that are too old to have children.

Since they are too old to have children, the post-reproductive age group will decline in number.

Which organism receives the least amount of energy from the producer?

shepuryov [24]

The owl would have the least amount of energy from the producer. The higher the organism is on the food pyramid, the less energy it will receive from the producer. For example, if grass is a producer, it has the most energy. Then, if a bunny eats the grass, it takes a part of the grass’s energy but does not take all of the energy. Then, a wolf eats the bunny. The wolf gets a part of the bunny’s energy but not all. The wolf has received the least amount of energy from the grass.

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp m

kodGreya [7K]

Answer:

A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.

Explanation:

Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.

Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
