Answer:
D. The direction of filtration can be into or out of the blood, but reabsorption always involves fluids entering the blood.
Explanation:
I believe that this is the correct option since filtration can occur in blood vessels and lymphatics, that is why it can be inside or outside the blood, that is, the filtration can be bidirectional.
While the reabsorption is to be able to re-integrate it to the lumen of the capillary or the blood vessel, thus generating an uptake of certain chemical compounds, and this movement or flow is towards the interior of the capillaries, that is, towards the inside of the capillary.
The team of Hunt had designed an experiment to test the hypothesis of the effect of BPA on mice. The daily doses of BPA was administered into the female groups of mice for 3, 5 and 7 days and then the genetic abnormalities which occured during meiosis, chromosome division or egg formation were studied.
The steps followed in this experiment in order are as follows:
- Observation- The mice eggs in plastic cages when washed using harsh soap showed problems during the cell division stage which caused genetic abnormalities.
- Question- If the bisphenol A from the plastic affected mice in the damaged cages.
- Hypothesis- If the frequency of the genetic abnormality was affected by the exposure to bisphenol A.
- Prediction- The level of exposure of mice to bisphenol A was proportional to the increase in genetic abnormalities.
This is referred to as the critical concentration, it is the exact concentration of the subunits that allows for equal growth and degradation of the filament.
Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)
Explanation:
In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.
Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.
A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:
--> the chromosomes replicate once and
--> the nucleus and cell duplicate ( divide equally) twice.
As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.
I think there was probably like 400
