Answer:
<em>The genotype of the mother will be Bb.</em>
Explanation:
A punnet square can be described as a diagram which is made to depict the outcome of a cross.
In the scenario discussed in the question, the genotype of the male parent will be bY. This is because he has the recessive black spots. As he is a male, he'll only have one allele for this gene.
In order to have one of spot design for each gender, the mother will have the genotype Bb.
The punnet square will be as follows:
b Y
B Bb BY
b bb bY
The body will stop making proteins that need it
Answer: 1. do honeyguides in different areas of the world have a similar symbiosis with humans?
2. how old are the birds when they learn to respond to the humans' calls?
3. could other birds in the region form a similar symbiosis with humans?

Answer:
Processing and packaging of cellular materials prior to export
Explanation:
Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.
The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.
Answer:
The DNA strands are not free in the nucleus, but forming a compact structure called chromatin along special proteins, known as histones. The chromatin structure has an important role in gene expression, as the level of compaction and the histone modification act as signals for the transcription machinery
In order to be transcribed, different areas in the genome need to unfold from the histone proteins, so the RNA polymerase can access the DNA.
That means, <u>that DNA sequences that transcribe at high rate, are more often unfold from the histones, and more exposed to other proteins to bind them. Particularly, those areas are more sensitive to the attack of endonucleases, such as DNAse I.</u>
As a consequence, an assay of DNAse I digestion can be used to identify highly sensitive or resistant to DNAse cleavage areas in the genome, and therefore serve as an insight to which sequences are more and less transcriptionally active.
