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.
Answer:
herbivores (plant-eaters)
Explanation:
They eat primary foods like plants
Answer:
the symbol for nitrogen is N
Explanation:
Answer:
The foxes would have brown fur all year long.
Explanation:
The foxes would have brown fur all year because the change in the environment will not occur. If the change not occur in the climatic conditions, then the foxes did not change the colour of the fur so the brown colour remains for all year long. The colour of fur changes when the change in climate occurs so if there is no change in the climate so change occur in fur colour of foxes.
