Answer:
<h2>If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting then the frequency of men and women differs.
</h2>
Explanation:
Red-green color blindness: color blindness is an X-linked recessive disorder. The male having this disease will transmit his X chromosome (with the mutation) to his daughter, who will then be a carrier of the disease.
If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting then the frequency of men and women differs.
Male inherit its X chromosome only from mother and no X chromosome from father, having one Y chromosome but female receive one X chromosome from father and one from mother, having no Y chromosome, So if the paternal allele is silenced then the males are no affected.
Answer:
G1 phase causes the cell to grow in size and produce new organelles, which prepare for S phase, when the DNA replicates. Answer 3: Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis.
Explanation:
The amount of greenhouse effect on Earth is directly proportional to the concentration of greenhouse gases in the atmosphere. In this era of industrialization, although it may seem that it has greatly improved the global economy, it also downplays the importance of consistently upholding our role as a steward to Earth.
The most common types of human activities that continuously worsen the greenhouse effect are: burning of fossil fuels, agriculture, and industrial processes.
The burning of fossil fuels such as coal, oil, and gas emits carbon dioxide which accounts for approximately three-quarters of the warming impact caused by the greenhouse gas emissions. This is amplified significantly through deforestation.
Methane, which accounts for 14 percent, and nitrous oxide, which accounts for eight percent are one of the major greenhouse gas emissions on earth. This can be sourced out from livestock and rice fields and also fossil fuel extraction and organic waste decay in landfill sites.
Industrial processes would incept fluorinated gases which accounts for one percent of the warming effect of current human greenhouse gas emissions.
Although it may seem that the values are not that high, but it must also be taken into consideration the several or a superfluous number of industries all around the world that simultaneously worsens the already groveling site of the continuously deteriorating and exploited planet Earth.
<span>The answer is A -The red geranium is heterozygous for red flowers (Rr).
We know that the red flower, to be red needs to have at least a dominant allele, so it could be either Rr or RR.
Let's try both scenarios.
If the white</span><span> geranium (rr) is being crossed with RR, all the offspring would be red with genotype: Rr.
On the other hand, if the flower is Rr and it's being crossed with rr, that would result in </span><span>half of the new generation plants having red flowers and the other half white flowers.</span>
Deductive reasoning, which is a type of reasoning where a general fact is broken down into a more specific case to make an inference. This general fact can be a broad branch of knowledge then gets into its parts that may comprise this broad knowledge. I hope this helped.
