Hi, what are the “following” options? I’d love to help! Thanks. :)
Earthworms have no special respiratory organs. Gases are exchanged through the moist skin and capillaries
Answer:
Steroid hormones
Explanation:
Steroid hormones are the second largest groups of hormones. They are made up of small cholestrol units and are fat soluble, therefore they can pass easily through cell membranes.
Function:
They have roles in many vital functions of our body such as salt and water balance, formation of sexual traits,immunity related functions,metabolism and improving health by withstanding injuries.
Mode of action:
- Steroids being hormones can effect the processes of body in two ways: They affect the transcription of genes involved in synthesis of certain proteins- this is called genomic level action.
- They can affect by binding with specific membrane receptors like G-proteins, Ion channels and transporters- non genomic level function. Through these ways, they can affect many mechanisms occurring inside the cell.
Hope it helps!
Having a high surface area helps so yes in the human body villi is an example of a structure that increases surface area to increase absorption rates.
Answer:
I. Responds to changes in ambient temperature.
II. Regulates sleep and wakefulness.
III. Regulates the release of thyroid stimulating hormone.
IV. Evokes nausea during anxiety.
Explanation:
Hypothalamus can be defined as a small portion of the mammalian brain responsible for the secretion of hormones through the stimulation of the pituitary gland.
It is located between the midbrain and the thalamus. Also, hypothalamus is the most inferior portion in the diencephalon of the forebrain.
Basically, hypothalamus is the most important portion of the brain in vertebrates that controls various bodily functions.
The functions of the hypothalamus includes;
I. Responds to changes in ambient temperature.
II. Regulates sleep and wakefulness.
III. Regulates the release of thyroid stimulating hormone.
IV. Evokes nausea during anxiety.
