B) Endocrine disruptors mimic hormones that regulate critical biological processes
Answer:
See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome
Explanation:
According to the position of the centromere, chromosomes can be of 4 types namely:
- Metacentric
- Acrocentric
- Telocentric
- Sub-metacentric
A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.
Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.
Telocentric chromosomes have their centromeres at one end of the chromosome.
Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.
The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.
It seems to me the correct answer would be nucleous
In the scientific method first of all is you need to identify the problem, the problem to your question is why does the dog circle its bed before lying down. Second is the observation to gather some data, you need to observe the dog if what could be the possibility the the dog may do that action. The third is the pre hypothesis, you need to came up with an idea why does the dog do such and action for example the needs to find a correct spot to make itself comfortable and lastly the hypothesis, this should answer to your question or your problem. So my hypothesis is that dogs are one of the animals that are those difficult to find a place to sleep and some of that kind of animals are cat, before they lay on their bed, they have to circle to find a spot that could fit its body to be more comfortable when the dog sleep
Answer:
Pond
Explanation:
Ponds are inland water bodies that are usually smaller in surface area than a lake and nonflowing in contrast to rivers or streams. However, a pond is a shallow freshwater source that inhabits organisms' life (plants and animals alike).
Due to the shallow state of a pond, light penetrates to the bottom, hence, allowing the constant growth of plant life. Therefore, PONDS are freshwater sources that contains a permanent shallow body of water with plant life throughout.
