Answer:
The correct answer is - 1, 4, 3, 2.
Explanation:
It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX
After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:
STUVWX
SWVUTX
Thus the second sequence after Ist inversion would be SWVUTX
2nd inversion, Third sequence:
SWVUTX
UVWSTX
Thus the third sequence after 2nd inversion is UVWSTX
3rd inversion, fourth sequence:
UVWSTX
UVXTSW
Thus, the fourth sequence after 3rd inversion is UVXTSW
Answer:
The correct answer is metaphase.
Explanation:
During metaphase, the lining up of the chromosomes takes place at the metaphase plate, under the influence of the mitotic spindle. In each of the chromosomes, the sister chromatids are held together with the help of microtubules from the contrary spindle poles.
In metaphase, the spindle has captivated all the chromosomes and aligned them in the center of the cell, which is ready to differentiate.
Answer:
The removal of soil will increase the rate of erosion and the flattening of the mountain will change the direction in which water flows off of the mountain.
I think it is D: back muscles.
The correct answer is Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.
At the time of hunger, the blood glucose level decreases, and glucagon at that time, that is, the hormone discharged by the islets of Langerhans increases the level of sugars in the body. The stored glucose in the liver gets discharged due to the presence of glucagon, which eventually elevates the level of glucose in the blood.
In the given case, when Kai ate the cookies, the level of glucose in the blood got increased and even elevated from the normal level in the blood. At that time, the insulin hormone is discharged from the islets of Langerhans, which helps the cells of the body to absorb the molecules of glucose and thus lowers the concentration of glucose in the blood. Therefore, both the hormones help in monitoring the levels of glucose in the body.
