<span>The brain is a very complex organ in humans. Although we still have a lot to learn about it, decades of studies in both living and dead humans had revealed that the brain is crosswired, meaning the right side of the brain controls the left side of the body and viceversa. It’s also the part of the brain associated with arts and our creativity. Therefore the answer is B</span>
B. In order of increasing atomic Mass :)
Answer:
not always confined to blood vessels and is under lower pressure than in closed circulatory systems
Explanation:
In an open circulatory system, blood is not always confined to blood vessels and is under lower pressure than in closed circulatory systems. This is because an open circulatory system is a system where blood, may be directly open to the environment in various places throughout the body such as the digestive tract, as opposed to being sealed in arteries and veins. Such a system is mostly found in insects and some animals such as snails or clams.
Answer:
p=0.9
Explanation:
The frequency of the different genotypes is as follows:
- AA = 0.81
- Aa = 0.18
- aa = 0.01
There are 2 alleles for this gene, the dominant allele <em>A</em> appears twice in the homozygous dominant genotype and once in the heterozygous.
Then, the frequency of the <em>A </em>allele, <em>p</em>, can be calculated as:
p= freq(AA) + freq(Aa)/2
p= 0.81 + 0.18/2
p=0.9
Answer:
The correct answer will be option-A.
Explanation:
During anaphase, the spindle microtubules help the segregation of the chromosomes from the center of the cell at the metaphase plate.
These microtubules get attached to the chromosomes at kinetochore which helps in pulling of the chromosomes to opposite poles. The microtubules pull apart the sister chromatids when cohesin proteins degenerate.
The chromosomes do not show jiggling movement at the metaphase plate and thus, option-A is the correct answer.
