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:
Lateralisation of the brain function.
Explanation:
The brain is divided into 2 parts which are: the right hemisphere and the left hemisphere.
The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other.
Examples of lateralised functions include:
Language, sensory processes, value systems etc.
Answer:
Explanation:
Kingdom platae includes includes alga (green, brown and red), liverworts, mosses, ferns and seed plants with or without flowers.
Answer:
clumped
Explanation:
Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. giraffea do not have to move very much to find mates, organisms have better protection from predators, and there is more access to food resources.
Sweating cools us down in two ways. Firstly sweat is wet so it cools down your body. Secondly, it evaporates which takes away some of our body heat. We sweat when we're hot and it helps to bring our internal temperature levels lower when it gets too high on a hot day, therefore assisting in thermoregulation.
