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 suprachiasmatic nucleus influences the release of melatonin by its effect on the ________________.
anyanavicka [17]

Answer:

Pineal gland

Explanation:

The suprachiasmatic nucleus is the paired nucleus made of about 1000 neurons each in the hypothalamus. The suprachiasmatic nucleus is involved in maintaining the endogenous clock or the internal clock.

The suprachiasmatic nucleus controls the circadian rhythm by controlling the amount of melatonin. The melatonin is produced by the pineal gland from the serotonin and tryptophan precursors.  The hypothalamus thus controls the amount of the melatonin by regulating the pineal gland.

Thus, Pineal gland is the correct answer.

Which organic molecules form the major structural materials of the body?
dangina [55]

Answer:

Proteins

Explanation:

They are found everywhere in the body from muscle, cell membranes, hair, enzymes, and etcetera and are responsible for the phenotype of organisms. Proteins are the ultimate expression of genes in the DNA of organisms. The DNA is transcribed by DNA polymerase into mRNA, then mRNA is translated into protein by ribosomes. This general rule is called the central dogma.

[100 PTS] Name one controversy that has resulted from the Human Genome Project. Using college level writing, make a logical argu
BaLLatris [955]

Answer:

One controversy that has resulted from the Human Genome Project is the ethics of genetic engineering and whether it should be used to create so-called "designer babies." Proponents of genetic engineering argue that it has the potential to eliminate genetic disorders and diseases, and that it could improve the overall health and well-being of future generations. For example, parents could use genetic engineering to ensure that their children have a lower risk of developing conditions like diabetes or heart disease.

On the other hand, opponents of genetic engineering argue that it could lead to a number of social and ethical problems. For instance, some people worry that genetic engineering could be used to create a society of genetically superior individuals, leading to inequality and discrimination. Additionally, opponents argue that we do not yet fully understand the potential risks and long-term effects of genetic engineering, and that we should therefore proceed with caution. They also raise concerns about the potential misuse of genetic engineering, such as using it to create individuals with enhanced physical or intellectual abilities for military or other nefarious purposes.

In conclusion, while genetic engineering has the potential to bring many benefits, there are also valid concerns about its potential consequences. It is important for society to carefully consider these issues and to proceed with caution.
