Answer:
At the end of mitosis, __two________ daughter cells that are genetically _____similar_____ are formed, while at the end of meiosis, _____four_____ daughter cells that are genetically _____distinct_____ are formed.
Explanation:there are two types of cell division; mitosis which occurs in somatic cells and meiosis which occurs in reproductive cells.
In mitosis, division occurs once leading to the production of two daughters cells.crossing over does not occur in the chromosome, so the daughter cells are genetically identical to the parent cell.
In meiosis,cell division occurs twice ,(meiosis I & II),leading to the production of four daughter cells.
Crossing over occurs,leading to genetic variation in the daughter cells.
Answer:
1. It is a highly contagious disease transmitted from person to person and thereby it is expected that infected persons carried the virus to America
2. Microcephaly is a serious birth defect where a baby’s head is much smaller than expected.
3. Occipital bone. CNS malformations: ventriculomegaly, parenchymal and periventricular calcifications and cortical migration anomalies
Explanation:
The Zika virus (Flaviviridae) causes a contagious disease and it is transmitted by Aedes mosquitoes, which are also the main vectors of the dengue virus. Microcephaly is a condition where the baby’s brain has not developed properly during pregnancy, and it has been shown that this birth defect is associated with the Zika virus. During 2015 in Brazil, the incidence of infants with microcephaly born from mothers that contracted this disease during pregnancy was higher, thereby suggesting an association between both conditions. Baby health problems associated with Zika infection include microcephaly (skull partially collapsed), joints with limited motion, etc.
The answer is going to be letter A
<span>The right answer is D. males have only one copy of the X chromosome.
</span>Hemophilia is a rare hereditary bleeding disorder disease. The blood of hemophiliacs does not coagulate normally. Bleeding is not more important, but without treatment, they can be more frequent and last longer than normal. Hence the importance of good monitoring and good treatment.
<span>The 2 types of hemophilia A and B are recessive and X-linked, but a third of hemophilia correspond to a de novo mutation. It is observed that a man who wears the X is always affected by the disease (because he has only one X chromosome in its genome) whereas the woman is only a carrier (she has two X chromosomes, so it can carry a safe X and a mutated X without being attempted by the disease but can transmit it to her descendants). This must be taken into account for genetic counseling.</span>
Answer:
The leaves no longer have water, which means that there is little osmotic pressure which keeps it turgid.
Explanation:
The stem still contains water because of the capillary action that occurs. However, since there is no strong attraction, the water cannot be pulled to the leaves.
