Answer:
Two gametes end up with 30 chromosomes, one gamete will have 31 and one will have 29.
Explanation:
During meiosis, a single diploid cell divides into four haploid cells with half the chromosome number than the parent cell.
During meiosis I, homologous chromosomes separate and the chromosome number in the two daughter cells goes down by half. During meiosis II, the "sister" chromatids separate, and the chromosome number in the respective daughter cells remains the same.
Non-disjunction of a single dyad in meiosis II causes that one of the daughter cells will have an extra chromosome, and another will be lacking one. The two other gametes will be normal.
I drew a simple example of what would happen during meiosis of a 2n=4 cell if there was non-disjunction in a single dyad during meiosis II.
Explanation:
Yeasts and filamentous fungi are extensively used as model organisms for eukaryotic genetic research, including cell cycle regulation, chromatin structure, genetic recombination and gene regulation.
Answer:
D. Specialist Species
<h2>
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?</h2>
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
A Safety Data Sheet refers to a detailed information document prepared by a manufacturer of hazardous chemicals. It describes the physical and chemical properties of the product.
<h3>What is
Safety Data Sheet?</h3>
- A Safety Data Sheet refers to a detailed information document prepared by a manufacturer or importer of hazardous chemicals.
- Describes the physical and chemical properties of the product.
- A safety data sheet provides comprehensive information about a chemical, including its properties physical, health, and environmental hazards; and protective measures or safety precautions to be followed in handling, storing, or transporting materials.
- Safety data sheets inform users about product hazards, how to use the product safely, what to expect if recommendations are not followed, how to recognize symptoms of exposure, and what to do in an emergency .
- Safety data sheets provide information about chemicals and help users of those chemicals to make risk assessments.
- They describe hazards arising from chemicals and provide information on handling, storage, and emergency procedures in the event of an accident.

Answer:
glucagon
Explanation:
Glucagon is a hormone that is involved in controlling blood sugar (glucose) levels. It is produced by the alpha cells, found in the islets of Langerhans, in the pancreas, from where it is released into the bloodstream.
