Answer:
concentric contraction
Explanation:
A concentric contraction causes muscles to shorten.
Answer:
The current answer is a. Bacterial culture
Explanation:
Bacteria are used in epidemiology laboratory and bacteria can spread and cause disease if the correct lab procedures are not followed.
So according to the lab safety sheet bacterial culture is the potential hazard that will be present in the laboratory during the Epidemiology & Laboratory Techniques lab. There are different levels of biosafety according to the threat posed by the bacterial culture on which epidemiological study is going on.
The biosafety sheet helps in featuring the epidemiology of bacterial culture, transmission mode, availability of medical interventions, suggested biosafety levels, etc. So the right answer is a.
Answer:
The main function is protection, breathing and support.
Explanation:
An exoskeleton covers the entire surface of arthropod animals, such as arachnids, insects, crustaceans, etc. Its main function is the protection, breathing and support of the muscular system, favoring its fossilization.
nerve cell is an examole of a cell that divides often
Darwin’s Finches: Darwin observed that beak shape varies among finch species. He postulated that the beak of an ancestral species had adapted over time to equip the finches to acquire different food sources. This illustration shows the beak shapes for four species of ground finch: 1. Geospiza magnirostris (the large ground finch), 2. G. fortis (the medium ground finch), 3. G. parvula (the small tree finch), and 4. Certhidea olivacea (the green-warbler finch) the Grants measured beak sizes in the much-reduced population, they found that the average bill size was larger. This was clear evidence for natural selection of bill size caused by the availability of seeds. The Grants had studied the inheritance of bill sizes and knew that the surviving large-billed birds would tend to produce offspring with larger bills, so the selection would lead to evolution of bill size. Subsequent studies by the Grants have demonstrated selection on and evolution of bill size in this species in response to other changing conditions on the island. The evolution has occurred both to larger bills, as in this case, and to smaller bills when large seeds became rare.
