Answer:
Hormones are controlled by a
(negative)
feedback system between the glands that produce this hormone and the concentration of blood calcium ions. If the level of ions is
(low)
,hormone secretion is increased. This causes resorption by cells called
which releases both calcium and phosphate ions into the blood stream.
Explanation:
Negative Feedback a the process in your body that helps to maintain Homeostasis. If some variable changes a value in your body, like your ion levels, your glands produce a hormone that causes resorption by cells. This releases both calcium and phosphate ions into the blood stream and therefore your ion levels go back to normal.
Hope this helps!
Answer:
1. Green beetles and red beetles exist in the environment.
2. Birds that eat the beetles move into the environment.
3. Red beetles are eaten by birds, but green beetles aren’t eaten.
4. Green beetles pass on their color trait to future offspring.
5. The entire population of beetles eventually becomes green in color.
Explanation:
According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
The answer is the dendrites offer a big apparent area for links from other neurons. The dendrites are the main open or input areas and offer an enormous surface area for receiving signals from other neurons. They have spines appendages in which come to close interaction with synapses with other neurons.
Answer:
After this treatment, the investigators should expect to get a mixture of the desired enzyme, plus fragments of the peptide used to desorb the enzyme in question.
This would be the result of using a peptide as a desorption solution when the desired protein is a protease,
Assuming that the protease retains its activity in the medium in question, and that the peptide can act as a substrate (which would make sense), as the peptide solution is added, it will interact with and bind to the antibody, but some molecules will also interact with the active site of the enzyme as it desorbs and passes through, culminating on the elution of the hydrolized part of the peptide along with the enzyme.
