Explain how DNA replication differs in prokaryotic and eukaryotic cells?
Sindrei [870]

In prokaryotic cells, there is only one point of origin, replication occurs in two opposing directions at the same time, and takes place in the cell cytoplasm. Eukaryotic cells on the other hand, have multiple points of origin, and use unidirectional replication within the nucleus of the cell.

Which statement describes asexual reproduction but not sexual reproduction
svetoff [14.1K]

Answer:

The question is incomplete, the correct question is;

Which statement describes asexual reproduction, but not sexual reproduction? A) New organisms are formed only after fertiliztion. B) A single cell will not develop into a full organism. C) Daughter cells contain half the genetic material of the parent cell. D) Daughter cells contain the same genetic information as parent cells.

Answer is option D. Daughter cells contain the same genetic information as parent cells.

Explanation:

The process in which organisms creates their offspring is called reproduction and the two types of reproduction are asexual reproduction and sexual reproduction.

In asexual reproduction, the offspring are produced from a single parent. They are genetically identical to each other and to the parent. Binary fission, fragmentation, and budding are the different methods of asexual reproduction. Examples of organisms which reproduce through asexual reproduction include bacteria, yeast, amoeba, hydra etc.

In sexual reproduction, the offspring are created by two parents and they are genetically unique.  The gametes are reproductive cells present in the parents, produced by meiosis. They are haploid cells containing only half the number of chromosomes. The process in which the gametes from two parents combine to form a zygote (fertilized diploid cell) is called fertilization, where the zygote has twice the number of chromosomes. The zygote develops into a fully formed organism, which has a unique combination of characteristics inherited from both parents.

_____ is an unpleasant side effect that alcohol withdrawal creates for an alcoholic. excessive sleepiness leptokurtic reaction c
bezimeni [28]
The correct answer is "delirium tremens"
<span>
In the event of abrupt cessation of alcohol use, there will be an adaptive response of the central nervous system leading to overactivity which explains the withdrawal symptoms. In the event of central nervous system hyperactivity, mild symptoms include but not limited to insomnia, tremors, mild anxiety, headache, and diaphoresis; these symptoms appear usually within six hours of cessation. Withdrawal-related seizures characterized as generalized tonic-clonic convulsions as well as alcoholic hallucinosis or hallucinations related to abrupt alcohol cessation may occur in moderately severe cases. In most severe cases, delirium tremens may occur and this is characterized by hallucinations, disorientation, tachycardia, and agitation. </span>
