A biological community is a community with an interacting group of many species in a common area. They can be interdependent on each other. For example : Animals depend on plants for oxygen and the plants are dependent on animals for carbon dioxide ( necessary for photosynthesis ).
Answer: Elements
Explanation: Elements are unique forms of matter with specific chemical and physical properties that cannot be broken down into smaller substances by ordinary chemical reactions.
Answer:
A
Explanation: Solid's particles are compacted together so C would be ice, water is not is compact as ice is so water would be B, and lasty gas is well gas so it moves around freely which means the gases particles aren't as compact as water and ice, so gas would be A
Answer:
True
Explanation:
The calcitonin/calcitonin gene-related peptide (CALCA) gene is used to encode different peptide sequences (i.e., calcitonin hormone, calcitonin-related peptides and katacalcin) through alternative RNA splicing. These peptides have different functions. Calcitonin is a hormone mainly produced by cells of the thyroid gland, which is involved in the control of levels of calcium and phosphate in the blood. Moreover, katacalcin is a peptide synthesized from the same precursor of calcitonin (and therefore also mainly produced by cells of the thyroid gland), which is implicated in both calcium regulation and skeletal maintenance. Finally, the calcitonin gene-related peptide (CGRP) is a peptide mainly produced by sensory nerves (type Aδ fibers ), which is involved in pain pathways. The CALCA gene has attracted considerable attention from geneticists because it is specifically expressed in neuroendocrine tissues in normal conditions and abnormally induced in septic conditions (i.e., during the body's extreme response to an infection).
They're celled subsistence farmers, their farming practice is subsistence farming, where most of the product they grew or reared are for themselves and their families, they usually don't take the products to the markets for commercial purposes, instead those who do that are practising commercial farming.
