Explanation:
A rock would experience a temperature of 5500°C is about the core which is at a depth of 220km.
But let us use the earth's geothermal gradient to solve this problem.
The geothermal gradient is the rate at which temperature is increasing with depth.
The geothermal gradient 25°C/km
At 5500°C,
5500°C x
= 220km
But this is not so in nature, there are other heat sources that contributes to increasing temperature with depth such as radioactive heat and frictional heat.

Answer:
The chromatids contain the maternal DNA only.
Explanation:
They must contain half the original number of chromosomes. It must contain only one chromosome in place of each homologous pair of chromosomes, so it is endowed with either the maternal or the paternal copy of each gene but not both.

I think the answer would be C) There is a problem with overfishing. Ban fishing for large fish so their size and population can recover, but allow the fisherman to take smaller fish.
banning fishing all together or ignoring the problem would definitely not work and bringing in a new species could disrupt the ecosystem and cause more of an issue.
Answer:
The correct answer will be- the cells of the xylem
Explanation:
The aphids feed on the plant by puncturing the vascular tissues especially phloem and sucking the phloem sap as it contains the sugar and other organic compounds.
If an inexperienced aphid mistakenly feeds on the plant vascular tissue which sucks the fluid from the gut of the aphid, therefore, the tissue will be xylem. Xylem transports the water and minerals due to suction pressure or transpirational pull which also result in the suction of the fluid of the gut of an aphid.
Thus, the cells of the xylem are the correct answer.
Answer:
The correct answer is "True".
Explanation:
It is true that the major role of absorption in the ileum is to reclaim bile salts to be recycled back to the liver. The ileum is the final part of the small intestine, serving as the terminator of the ileocecal sphincter. The ileum is the final step of absorption in the small intestine and while most nutrients are absorbed in the jejunum, the ileum absorbs the bile salts and some vitamins, like vitamin B12.
