The most abundant in the atmosphere are Nitrogen, Oxygen, Argon, and Carbon Dioxide. All of these combined take up about 99.9% of the Earths atmosphere
Hope this helped!! :D
Answer:
The likely genetics will be incomplete dominance for such a phenomenon.
Explanation:
Incomplete dominance occurs when the dominant allele is not fully or completely showing dominance over the recessive allele.
When parents with such alleles are crossed, the resulting offsprings will show a physical trait which is intermediate and different from both of the parents.
In the scenario discussed in the question, the red colored mother and the white colored father are producing offspring that have light red coat. This is because the red color is not completely dominant over the white color. Hence, an intermediate light red color is seen in the offspring.
SA Node<span> which is also known as the sinus node, is the natural pacemaker of
the heart. It controls the heart rate by generating electrical impulses
and then sending electrical signals through the heart muscle, causing
the heart to contract and pump blood throughout the body. </span>
The SA Node is located in the outer layer of the right atrium of the heart, near the superior vena cava. It is made up of a group of cells (myocytes) positioned on the
wall of the right atrium, at the center of the heart and near the
entrance of the superior vena cava. These cells contract at a rate of
about 70-80 times per minute, which make up the natural heart beat.
