Answer:
yes it is yes it is abiotic factor
The process responsible for this is mass movement.
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.
The correct answer is option d, that is, there is a forest where many trees are absorbing carbon.
The tendency of the forests to absorb carbon dioxide is associated with numerous elements, that is, how the forests are managed, the age of the trees, the nutrient content of the soil, the local environment, and the level of precipitation.
It has been found that the established forests, that is, found from the boreal forests in the north to the tropical rainforests in the south, captivates about 8.8 billion tonnes of carbon dioxide in a year.
