Answer:
the nucleus is divided into two nuclei
Explanation:
The karyotype is a test that provides information on the number, size and shape of chromosomes in a sample of body cells. It can be used to find out whether a fetus has some chromosome defects that could cause developmental problems, birth defects or disability. It can also be used for determining the sex of the baby.
Few advancements in scientific knowledge were made.
Scientists discovered new evidence to support their theories.
Scientists used observations and mathematical data to solve problems in new ways.
<u>Explanation:</u>
At first the Ptolemaic model suggested that the earth was the centre of the solar system around which the sun, moon and other planets revolved. This Copernican revolutionised by finding Sun in the centre of the solar system around which the earth and the other planets revolved. After his discovery the earth was just given a status of yet another planet.
The scientists who were researching on this made few advancements using their scientific knowledge and hence found new evidences to support their theory. Scientists then researched conducted experiments using mathematical calculations to solve their problems.
Complete question:
Question: Genes in different chromosomes _____ during meiosis. Genes that are very close together in the same chromosome are _____.
a) do not assort independently; unrelated
b) assort independently; unrelated
c) assort independently; linked
d) do not assort independently; linked
Answer:
c) assort independently; linked
Explanation:
During anaphase-I of meiotic division, homologous chromosomes are moved to the opposite poles of the cell. This segregation also separates the alleles of genes present on the chromosomes to the opposite poles. The segregation of genes is a random event which means that the alleles of one gene segregate independently of the alleles of some other gene. This requires that the genes are present on separate chromosomes.
The genes present close together on the same chromosomes are linked. This means that they are inherited together and do not exhibit independent assortment.
Risk factors and prevention of diabetes mellitus
Explanation:
It is to enable clients to prevent illness is one of an
important nursing function. The nurse should most appropriately educate the
family about the risk factors and prevention of diabetes mellitus. Knowledge of
the medications used to treat diabetes is not necessary at this time and does
not help meet the family's needs. The severity of the client's disease does not
have an impact on the family's health. Knowledge of the cellular metabolism of
glucose is not necessary for the family's health.
