The right answer is metaphase II.
The process is performed in two nuclear and cytoplasmic divisions, called first and second meiotic division or simply meiosis I and meiosis II. Both include prophase, metaphase, anaphase, and telophase. First division prophase is long and consists of 5 stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. It is at this point that genetic recombination takes place at the level of chiasmus.
During meiosis I, the members of each homologous pair of chromosomes are paired during prophase, forming bivalents. During this phase, a protein structure, called synaptonemal complex form, allows recombination between homologous chromosomes. Subsequently, a large condensation of the bivalent chromosomes occurs and go to the metaphase plate during the first metaphase, resulting in the migration of n chromosomes to each of the poles during the first anaphase. This reduction division is responsible for maintaining the number of chromosomes characteristic of each species.
In meiosis II, as in mitosis, the sister chromatids comprising each chromosome are separated and distributed between the nuclei of the daughter cells. Between these two successive steps, there is no DNA replication. The maturation of the daughter cells will result in the gametes.
The answer is false. <span>In a </span>lytic infection, the virus enters the cell, reproduces viral offspring, and then releases the offspring as it destroys the cell.<span> that is the reason why it is false. i am 100 percent sure my answer is correct.
Hope this helps.
can you please make this the brainliest answer it would really help me. thank you :) </span>
Answer: please ask me for help and vote me brainliest :)
The intensity or refraction depends on the material
Explanation:
In the experiment, the purpose it to determine the effect of the material on the refraction index. The refraction index is the ration of the incident ray to the refracted ray. This relationship is known as Snell's law of refraction
where i and r are angles of incident an the refracted ray and n is the refractive index. The dense the material, the more the angle bends. This means that the angle of refraction, as measured by the protractor, is going to be large.
A host cell infected by a virus will activate the adaptive immune response through white blood cells that are called as lymphocytes.
There are two types of responses through cells: antibody responses and cell mediated immune responses. These responses are occur by different types of classes of white blood cells those are called as B cells and T cells.
These T lymphocytes use chemical messenger to activate other immune system cells so that the adaptive immune system can activate. It detect the infected cells and destroy the cell.
Antibody is a blood protein that is produced in body in response to the specific antigen.

The statement 'a crocodile-like animal is the ancestor of birds' is BEST supported by the information in the table (option A).
- Evolution refers to the biological process of descendence with modification.
- Evolutionary close species share functional and structural phenotypic features due to a same-origin during evolution.
- A crocodile is a reptile, and it has been shown that birds evolved from theropod dinosaurs (reptile).
In conclusion, the statement 'a crocodile-like animal is the ancestor of birds' is BEST supported by the information in the table (option A).
