Hormones secreted by the adrenal cortex that help to maintain glucose levels in the blood are called glucocorticoids. It is secreted by the middle region of the adrenal cortex. The principal glucocorticoids is cortisol also called hydro-cortisone. The overall effect of the glucocorticoids is to increase blood glucose levels. This helps to maintain appropriate blood glucose levels between meals. In times of prolonged stress cortisol is secreted in greater than normal amount to help increase glucose level to provide energy to respond to the stress. Cortisol also helps to counteract the inflammatory response. For this purpose, it is used clinically to reduce inflammation in certain allergic reactions, bursitis and arthritis, infections and some types of cancer.
Answer:
D. Carbon and oxygen form covalent bonds but sodium and chlorine form ionic bonds
Explanation:
Chemical bonds form between the atoms of elements. The types of chemical bondings that form are: covalent bond, ionic bond and more. Covalent bonds are bonds formed when atoms share valence electrons rather than transfer it. The shared bonding is in such a way that the outermost shell of both atoms are filled. This is the case of carbon and oxygen atoms in the diagram.
On the other hand, ionic bonding involves the transfer of electrons from one atom to another in order to form electrically charged ions that are bound to one another. This is the case of sodium atom, which has one valence electron in its outermost shell and transfers it to chlorine atom, which has seven electrons in its outermost shell. The sodium atom becomes a positively charged ion (+1) while the chlorine atom becomes negatively charged (-1).
Answer:
genotype:100% BW
phenotype: 100% dominant colour
The event order should be:
1. Ingesting food, the small bowel filled with food solutes and become hypertonic. It will attract water from the blood which is hypotonic
2. Food digested, some of it absorbed. The osmotic pressure inside bowel will be reduced.
3. All food is absorbed, the osmotic pressure reduced significantly makes it hypotonic. The blood attracts water as it is hypertonic. This will increase the blood volume
