Answer:

Genes coding for proteins involved in chiasma formation.

Explanation:

Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.

Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.

Where do queen bees lay eggs and larval bees are fed by worker bees
steposvetlana [31]

Answer:

1. Queen bees lay their eggs after within each cell inside a honeycomb.

2. True. Worker bees feed the larvae with a combination of nutrients, from nectar and pollen to bee milk and water.

Explanation:

1. Queen bees lay their eggs after within each cell inside a honeycomb (hive) <em>[</em><u><em>See image below]</em></u><em> </em>during the winter.

The queen is able to lay over two thousand eggs PER DAY! Each egg has an approximate size of 1 mm long. This process then leads to the formation of a whole new colony of bees.

<u><em></em></u>

2. True.

Worker bees have the largest density of all, that is, there are numerous worker bees within a colony. As their name "worker" implies, they have plenty of tasks to perform. For example, they have to clean the hive regularly, ventilate it during warm conditions or keep it warm during cold conditions, and also care for the queen. However, one the most important roles of workers is to feed the larvae, during this stage they are also called "nurse bees." These bees feed the young with a combination of nutrients, from <u>nectar and pollen to bee milk and water</u>.

Why do some regions specialize in "milk products" like cheese and butter rather than fluid milk? identify some of these importan
kati45 [8]
This happens because these regions are located further away from urban areas and the milk can easily get spoiled before it is delivered to the consumers. Therefore, dairy farms which are away from urban areas, process the milk in order to produce milk products that can last longer. Milk products such as butter or cheese can stay fresh for a longer period of time and they do not get spoiled before reaching the consumers. New Zealand is a place where this practice is quite common since it is located at a great distance from important markets, such as Europe and North America. Milk can be shipped at such a great distance only in the form of processed milk products.
