Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II. The correct option is D.
The division of gametic or sex cells is known as meiosis. The process of reproduction involves this. It takes eight phases to finish. It is split into two sections. The first and second meiosis.
When a cell is dividing, it is a haploid cell. One set of chromosomes makes up a haploid cell. It includes all of its chromosomes during meiosis. Chromosomes are hereditary material.
In the chromosomes in meiosis 1 a full set of chromosomes is present and in meiosis 2, the number is diploid (2N).
Therefore, the correct option is D,Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II.

Answer:
The answer is: Mackerels, perches, soles, eglefinos, mainly.
Explanation:
The codis very voracious and all the prey that is within reach is good for him, even the juvenile cod. But his favorite delicacies are asmall squid, and thewavy bucino. In their early stages of life they feed onkrill, zooplankton and crustaceans, before moving on to small fish such aschaplain and herring, the adult eats other fish such asmackerels, perches, soles, eglefinos, mainly.
The answer is: Mackerels, perches, soles, eglefinos, mainly.
B. inheritance of one allele, received from the healthier parent plant
C. inheritance of two alleles, both from the dominant parent plant
D. inheritance of two alleles, one from each parent plant
Answer:
Option D.
Explanation:
As stated in Mendel's law of segregation.
effect.
B. Disruptive selection divides a population into two new species.
C. Selective breeding creates a new species of dog.
D. A mutation spreads rapidly through a small population.
The example of genetic drift is A. The allele frequency of a population changes due to a bottleneck effect.
Genetic drift refers to random fluctuations in the frequency of alleles (variants of a gene) in a population over time. This can occur due to various factors, such as a reduction in population size or migration of individuals between populations.
The bottleneck effect is a type of genetic drift that occurs when a population experiences a sharp reduction in size, which can reduce the genetic diversity of the population. This can result in certain alleles becoming more common or being lost altogether, even if they were not necessarily more advantageous or disadvantageous for survival.
Disruptive selection (option B) and selective breeding (option C) are mechanisms of natural and artificial selection, respectively, and do not necessarily involve random fluctuations in allele frequencies.
Hence, A mutation spreading rapidly through a small population (option D) could be an example of genetic drift if it results in a change in allele frequency, but the fact that it spreads rapidly suggests that it may be under the influence of natural selection instead.

To become a Cardiologist, one would need to choose a relevant major in college like Biology or Chemistry, go to medical school, and then complete a residency in Internal Medicine and a fellowship in Cardiology. This process totals to about 14 years of education and training.
In order to become a Cardiologist, you will need to follow a certain educational path. Start by choosing a major in college that will lay the groundwork for medical school, such as Biology or Chemistry. After obtaining your undergraduate degree, you will then proceed to medical school, which typically lasts four years. However, becoming a cardiologist doesn't stop there. You'll then need to complete a three-year residency in Internal Medicine, followed by a three-year fellowship specifically in Cardiology. In total, from undergraduate to completion of your fellowship, you're looking at approximately 14 years of education and training.
