Answer: protein conformation has been destroyed due to heat
Explanation:
Proteins are made up of several polypeptide chains linked by hydrogen bonds, and peptide bonds among their amino acids subunits.
At elevated temperatures, the hydrogen and peptide bonds are cleaved resulting in change in conformation of the protein. At this point, cooling DOES NOT renature the protein, as its bonds have been broken.
Biodiversity decreases, and the overall health of the ecosystem decreases.
Answer: Option D
<u>Explanation:</u>
In a niche when two different species occupy a niche competition arises between them. In due course both the species fight for existence and nature selects the best adaptable one to win. The other species either reduces in its population or gradually in struggle for existence they deteriorate and die.
Hence a decrease in bio diversity happens here due to natural selection. If the biodiversity is decreased in a particular niche it affects the growth of different species which in turn affect the whole ecosystem resulting in decrease of the overall health in an ecosystem.
Answer:
The correct answer is option e. "pancreas".
Explanation:
One of the main function of the pancreas, is to produce insulin, a hormone that allows glucose to enter the cells in order to be used to produce energy. When the blood glucose level rises after a meal, the first organ to respond is the pancreas by secreting insulin and allowing the body to use the ingested glucose. Type 1 diabetes occurs when pancreas does not produce enough insulin and high levels of glucose remain in the blood.
Answer:
it will sink
Explanation:
water has density of 1 g/cm³
the object has density 2.5 g/cm³
It will sink in water as much more dens
The correct answer is: c. small intestine
The digestion of fat mostly occurs in the small intestine, but it can sometimes begin in mouth where lingual lipase breaks down some lipids. Before absorption, fats have to be emulsified (broken down to small droplets) and it is done thanks to pancreatic lipase from the pancreas and bile from the liver. Monoglycerides and fatty acids associate and form micelles (together with bile salts and phospholipids, vitamins and cholesterol). Micelles are necessary for the transport to the enterocyte, but only freely dissolved monoglycerides and fatty acids can be absorbed.
