Answer:
C
Explanation:
When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.
If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.
In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.
Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.
The toxins are the substances which decreases the conc. of oxygen in wzater and increase toxicity
Answer:
C.1 out of 2
Explanation:
The probability of the organism producing a gamete with one dominant allele and one recessive allele for these trait is 2 out of 4 which can be further reduced to 1 out of 2.
For a cross between Homozygous and heterozygous individual we will get 2 homozygous and 2 hetrerozygous individual. The heterozygous individual has one homozygous allele and one heterozygous allele
Answer:
The correct option is e
Explanation:
An inversion mutation is a situation in which a sequence of the gene on a chromosome breaks out and rearranges itself from reverse (to the beginning) and then attaches itself back to the point of breakage of the same chromosome.
From the question, mutation changed the gene sequence from ABC*DEFGH to ABC*DGFEH. From this mutation, it can be seen that the gene sequence "EFG" broke-out, rearranged itself from reverse to the beginning as "GFE" and then attached itself back to the points of breakage.
NOTE: This type of inversion is called paracentric inversion since the centromere (represented as * in the question) is not part of the breakage.
