Answer:
The main glands that produce sex hormones are the adrenal glands and the gonads, which include the ovaries in females and testes in males. Sex hormones are also important for a range of bodily functions and a person's general health.
Explanation:
adrenal glands and the gonqds pqrt of the body regulate sex hormones .
Answer: ion-channel-coupled receptors.
Explanation:
These channels are mainly involved with the fast transmission. These receptors are organized into the membrane and regulating or ion-flow channels according to their internal diameter and the predominant electrical charge of their constituent amino acids.
Ion channels can be activated either by membrane potential variation (VOC´S - tension-operated channels), as well as interaction with an agonist (ionotropic receptors), as well as mechanical stimulation or via intracellular agents such as calcium ions, cyclic nucleotides, inositol triphosphate, and G protein. This group includes the nicotinic cholinergic receptor, the GABA receptor, and the glutamate receptor.
Answer:
a. transcription
Explanation:
<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>
The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.
<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>
The only option that has no known effect on sugar transport in the phloem is transcription.
The correct option is a.
