Answer:
diffusion of the hormone through a target cell membrane
formation of a hormone-receptor complex
activation of a gene
cellular response to the hormone
production of a protein
Explanation:
Steriod hormone are primary hormones derived from lipids. Such as reproductive hormones i.e the testosterone and the estrogens, which are produced by the gonads (testes and ovaries). Steroid hormones are not soluble in water (they are hydrophobic). For a new cell to be activated by a steriod hormone, there are a lot of steps invovled, Steriod hormones must travel to their target cell bound to a transport protein (i.e diffusion of the hormone through a target cell membrane).
Once the hormone binds to the receptor in the targeted cell, a chain of events is initiated that leads to the target cell’s response (I.e formation of a hormone-receptor complex). Hormones plays a vital role in the regulation of physiological processes because of the target cell responses they regulate.
The message a hormone sends is received by a hormone receptor, (a protein located either inside the cell or within the cell membrane). The receptor will process the message by initiating other signaling events such as (activation of a gene) or cellular mechanisms that result in the target cell’s response. Hormone receptors recognize and respond to them (i.e cellular response to the hormone). Thus, the response triggered by a hormone depends not only on the hormone, but also on the target cell.
Once the target cell receives the hormone signal, it can respond in a variety of ways. The response may include the (production of protein synthesis), activation or deactivation of enzymes, alteration in the permeability of the cell membrane, and stimulation of the secretion of products. etc
Answer:
The correct answer will be- sac like structure called ascus.
Explanation:
Ascomycota is the largest division of the fungi with about 64000 species which reproduces by both the ways of reproduction.
The ascomycetes are named so because of their sac-like microscopic structure called ascus formed during the sexual reproductive phase of the fungi. A single ascus produces eight ascospores through meiosis under optimal conditions which form the fungi.
Thus, sac-like structure called ascus is the correct.
Answer:
Biotic would be all living organisms. A biotic would be non living like water air rock water
