This is a large, covalently-bonded molecule that has a repeated structural unit. This is a complex carbohydrate made from many different sugar molecules joined together. A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair.
Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.
2. The structure of a hammer is related to its functions as it shape and hard tip effectively does its job. (Smashing thing, etc.) Its anatomy directly correlates with its function.
Answer:
All the statements are true except the second i. e. the soil quality in an ecosystem Does not matter as much as soil quantity.
Explanation:
In an ecosystem both quality and quantity of water is very important. If the quality of water is not suitable, that it contains polluted substances so the health of the organism such as fishes and other aquatic animals will adversely affected and sometimes dealth occurs and the ecosystem will be negatively affected.
The central vacuole in a plant cell takes up most of the space. The vacuole stores wastes and nutrients, and also provides support and structure for the cell.
