Gametes with two heterozygous copies of a chromosome may result from nondisjunction in either meiotic division.
<h3>What three types of nondisjunction are there?</h3>
Nondisjunction can take one of three different forms: failing to separate a homologous pair of chromosomes during meiosis I; failing to separate sister chromatids during meiosis II; or failing to separate sister chromatids during mitosis.
<h3>How can you tell whether nondisjunction takes place in meiosis 1 or 2?</h3>
- Nondisjunction, which can lead to an aberrant amount of chromosome-bearing gametes, can happen during meiosis I and meiosis II.
- The primary distinction between nondisjunction in meiosis 1 and 2 is that whereas sister chromatids fail to separate in meiosis II, homologous chromosomes fail to separate during meiosis 1.
<h3>What are mitotic and meiotic divisions?</h3>
- Mitosis and meiosis are the two distinct processes of cell division.
- When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body.
- The cell division process known as meiosis is what produces egg and sperm cells. A vital process for life is mitosis.

Hey there! Let's solve the problem:
CD4 T cells activate CD8 T cells through an underhanded cycle including an antigen presenting cell (APC), customarily a standard dendritic cell (DC). An APC presents a peptide to a true CD4 T cell through a Class II MHC molecule.
The correct answer is C.
Glad i could help:)
Gametes or reproductive cells belong to haploid cause every of them has one half of chromosomes,23 pairs each , if they unite this is the time they are called diploid with complete traits and 46 chromosomes.
Answer: d. all the above
Natural resources can be classified into two main types:
1.Renewable resources
2.Non-renewable resources
Renewable resources are those which can be replenished and reused. These resources are abundantly present in the nature. Example wind, biomass. Non-renewable resources are those which cannot be replenished after single time use. Example fossil fuels, groundwater, natural gases, forests. These resources needs to be conserved and their use should be judicious. Government should participate to prevent excess and destructive use of natural resources. Such as it should prevent deforestation. Many buisnesses requires the use of fossil fuels and natural gases which should be limited as these resources takes several years to be produced under the heap of earth. Citizens should prevent the use of groundwater in excess as this is the water reservoir which takes many years to be filled by natural means such as rain, agricultural irrigation, river and lakes.
