Prescription medication is the least likely to affect the results and interpretation of a functional MRI.
Here are some of the factors that is most likely to affect the results of MRI :
- Caffeinated soda. Caffeinated soda tend to constrict the blood vessels in the brain, which will affect MRI results.
- cancerous growth, will create a huge shadow on MRI results
- sprained ankle, especially if it was fixed with metal bandage, will cause harm during MRI
Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
Answer:
G1 - S - G2 (may be is option D)
Explanation:
The interface begins with phase G1 where the cell increases its volume and the mass is doubled.
Then, we continue with the S phase where DNA and histones are synthesized.
Afterwardsy we reach the G2 phase where the chromosomes are duplicated.
Finally we reach, the begining of mitosis.
Answer:
Genetic diversity is important because it helps maintain the health of a population because a diverse set of alleles that can be valuable in resisting diseases, pests and other stresses. If the environment changes, a population that has a higher variability of alleles will be better able to evolve to adapt to the new environment and therefore survive longer. Hope this helps!
In metaphase, anaphase and telophase of meiosis 2 before cytokinesis the condition prevails.
<h3><u>Explanation:</u></h3>
Meiosis is the type of cell division which takes place in the gamete mother cells to produce gametes. Its a reduction division because the germ mother cells are diploid and gametes are haploid.
In the cells undergoing the meiotic cell division, the cells at first undergo DNA replication which make the DNA content of each chromosome doubled.
Then through meiosis 1, the cell undergo the reduction division which makes the diploid cell haploid. So here the cell with 10 chromosomes become cell with 5 chromosome. But the DNA content per chromosome remains doubled. This is restored by the second meiosis division where the chromosome becomes divided into chromatids with normal DNA amounts.
So in every steps of meiosis 2, untill the cytokinesis is achieved, the cell remains in the haploid yet double DNA amount condition.
