Answer:
Niche can be described as the role or position that a particular organism has in its ecosystem.
For example, honeybees which will gather nectar from flowers to make honey is an example of a niche. The particular role of honeybees in an ecosystem is to collect nectar in that ecosystem from different flowers and to produce honey. Other organisms living in the same environment will not perform the same function in the ecosystem.
Answer:
there are four types of protein structure;
- primary
- secondary
- tertiary
- quatenary
Explanation:
A protein is a very large biological molecule composed of a chain of smaller molecules called amino acids. Thousands of different proteins are present in a cell, the synthesis of each type of protein being directed by a different gene.
Determining the process by which proteins fold into particular shapes, characteristic of their amino acid sequence, is commonly called "the protein folding problem", an area of study at the forefront of computational biology. One approach to studying the protein folding process is the application of statistical mechanics techniques and molecular dynamics simulations to the study of protein folding. Protein folding enables them to perform different diverse functions.
Protein have a three-dimensional structure that enables them to perform diverse functions like transsport,structural support as building blocks and metabolic regulators as enzymes and hormones.
Answer:
As a transcription factor
Explanation:
Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.
The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.
The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.
Thus, as a transcription factor is correct.
