<h2>Answer:</h2>
Because same base pairs are arranged differently among organisms due to which there are so much variations in organisms.
<h3>Explanation:</h3>
- Variation in the organism is due to the genes.
- Every one have different DNA/genes which describes one's features.
- Genes are various arrangements of these four base pairs.
So same base pairs with different pattern arrangement causes variation among organism.
Answer:
They act to regulate the expression of specific genes (androgen-responsive)
Explanation:
Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".
Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.
This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.
This process helps to direct the development of male sexual characteristics.
Assuming its "resting" is the place in the middle of the wave crest and trough, the distance between the crest and the middle line would be considered its amplitude. The height of a wave is the distance between the crest and the trough, and wavelength is the distance between two crests.
Answer:
The lack of access to clean drinking water poses a serious health risk around the world, and funds must be raised to help achieve universal access.
