Answer:
While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma
Explanation:
The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.
However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.
Explanation:
The answer is c in my understanding
Answer:
Option a is the one, that is true.
Sister chromatids separate in anaphase of mitosis and anaphase Il of meiosis
Explanation:
After the interphase in the cell division cycle, the mitosis process begins, which is composed of 4 phases, prophase, metaphase, anaphase and telophase. The prophase occurs when the chromatin is condensed and the mitotic spindle is formed, the metaphase the chromosomes align along the cell equator, in the anaphase the separation of the sister chromatids occurs and in the telophase finally the heterochromatin is converted into euchromatin and the envelope is formed nuclear cell.
Meiosis, which is the cell division of germ cells, also has the same phases but they occur on two occasions: prophase I, metaphase I, anaphase I and telophase I for meiosis I and for meiosis II, prophase II, metaphase II, anaphase II and telophase II. In the anaphase I the homologous chromosomes are separated, they are condensed in the prophase II while in anaphase II the chromatids are separated.
The mutation in the somatic cells is known as somatic mutations. As they do not take place in the cells, which give rise to gametes, thus, the mutation is not inherited to the next generation by the sexual means.
On the other hand, the genetic mutations take place in the germline cells, that is, egg and sperm, because of this the mutations possesses the tendency to get passed on from one generation to another.
Thus, mutations are only passed on to offspring when they take place in germ cell DNA. The other kind of cells, the somatic cells refers to the rest of the cells in the body and mutations, which takes place in these cells do not get inherited further to the offspring.
Hence, the correct statements are mutations to gametes can be passed on to an organism's offspring and mutations to somatic cells are only present in the type of cell in which the mutation occurred.
I'm going to assume the answer is False.
