Melting ice is raising the water level in the oceans. Where is the ice coming from? What else is causing the ocean levels to ris

Tpy6a [65]

OK. So, first question first. The ice is a result of the water temperature dropping below 32 degrees Fahrenheit or 0 degrees Celsius. Question 2. There is a lot of things that could be happening to cause the ocean levels to rise. Such as Global Warming and the glaciers melting because of it. I know of some glaciers that melt at a rate of about 2 inches per year. Question 3. 80% of the light that hits polar ice is reflected back into space. Question 4. As far as I know, it doesn't do anything to reduce global warming. But then of course, I don't have as high of an education as some professional biologists. Question 5. Some energy is absorbed by the water. Some of it is reflected back into space. Again, I'm not quite sure, as I don't have as high of an education as some professional scientists. Question 6. It speeds up the melting of the ice because the sun is directly shining on it, therefore the ice is receiving quite a bit of heat. Question 7. The gulf stream is a powerful current in the Atlantic Ocean. Question 8. Not quite sure how it helps the climate in Europe. That might be a question to ask your science teacher. Question 9. Again, not quite sure. You should ask your science teacher. Question 10. It has made the temperature in them much warmer than before. Question 11. Well for starters, it has increased the rate of Forest Fires and House Fires therefore putting humans at a greater risk, as they could be inside their homes when they catch on fire, or they could be camping or something like that if a forest fire breaks out. That is pretty much all I know about how it affects humans. Question 12. I don't believe there is anything that we can do to reverse global warming, but we can reduce it by pumping less and less harmful toxins into the air, such as Carbon Monoxide. That is all I have for you today. Please let me know if this helped you out in any way!

Quiz which condition could lead to drawdown below the level of existing wells?

irinina [24]

Answer:

Continuous pumping of water causes drawdown. The water table lowers rapidly.

Explanation:

Water table is the level below which the ground is saturated with water.

During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.

But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.

To prevent this, the groundwater should be recharged and over drawing should be avoided.

Each body cell of a chimpanzee contains 48 chromosomes. After mitosis, how many chromosomes are present in each cell?

nekit [7.7K]

Answer:

During both mitosis and meiosis, DNA replicates first during S phase of interphase. Each copy (DNA molecule) is called chromatid. Before anaphase they remain together, joined by the centromere in the chromosome.

Part 1: How many chromatids and chromosomes are present at:

(a) anaphase of mitosis: During this phase sister chromatids split. We would have 48 chromosomes in each pole and 48 chromatides.

(b) anaphase I of meiosis: During this phase homologous chromosomes split, being a reductional division. In each pole we will have half the chromosomes we had after DNA replication. This is 24 chromosomes but 48 chromatides (remember they will split during anaphase II).

(c) anaphase II of meiosis: This is an equational division, we will have 24 chromosomes in each pole and 24 chromatides. Each chromatid is considered a chromosome.

(d) G1 prior to mitosis: During this phase DNA has not replicated yet and it is not condensed either. This formed is called chromatin. We will assign one chromatid for each chromosome. This is a somatic cell, so: 48 chromosomes and 48 chromatids.

(e) G2 prior to mitosis: After S phase, we have duplicated all chromosomes. We will assign two chromatids per chromosome: this is 96 chromatides and 48 chromosomes.

(f) G1 prior to meiosis: Before DNA duplication, 48 chromosomes, 48 chromatids.

(g) Prophase of meiosis I: After DNA replication, condensation of the chromatin takes place: 48 chromosomes, 96 chromatids.

Part 2: How many chromatids or chromosomes are present in:

(h) An oogonial cell prior to S phase: This is G1 phase, 48 chromosomes.

(i) A spermatide: This is the male haploid gametid, after meiosis: 24 chromosomes and 24 chromatids.

(j) A primary oocyte arrested prior to ovulation: They are arrested at prophase I of meiosis. This means their DNA is still duplicated and chromatides have not divided yet. 48 chromosomes and 96 chromatids.

(k) A secondary oocyte arrested prior to fertilization: They are halted at metaphase II of meiosis, meaning they have half the chromosomes (24) but chromatids are still together (48).

(l) A second polar body: They suffered the same process as the mature ovum but remained with little cytoplasm. They have 24 chromosomes and 24 chromatids.

(m) A chimpanzee sperm: They have completed both meiosis as well, they have 24 chromosomes and 24 chromatids.
