Answer:

c. Factors 1 and 2 may be influenced by both nature and human factors

Explanation:

The sea level rising and the change in the atmospheric gases are both processes that are influenced by the nature, as well as by the human activities. Naturally, the earth has its own cycles, known as Milankovich cycles, through which the Earth warms up, or cools down, resulting in change of the atmospheric gases, and in accordance to that, change in the sea levels depending on the global climate. The humans to have become a big factor in the past few hundred years. The reason for that is that the humans with their activity started to release lot of greenhouse gases into the atmosphere, especially CO2 and methane. That has been changing the composition of the atmosphere, and the temperatures have been rising. The higher the temperatures, the more ice is melting around the poles and on the high mountains, resulting in an increase in the sea levels.

If a germ-line cell from a frog contains 10 picograms of DNA during G1 of interphase, then how many picograms of DNA would be pr

DIA [1.3K]

Answer:

Explanation:

The cell cycle is composed of three states: interphase, cell division and resting.

The interphase is composed of 3 phases: G1, S and G2 (in this order). During this state the cell prepares itself for cell division. As part of the preparation the cell duplicates all its genetic material, that is, all its chromosomes. This duplication is done during the phase S.

During the meiotic cell division (composed of meiosis 1 and meiosis 2) a single diploid mother cell (with duplicated chromosomes) produces four haploid daughter cells. the meiosis 1 produces two haploid cells with duplicated chromosomes, and the meiosis 2 produces 4 haploid cells with normal chromosomes (no duplicated).

If a germ-line cell from a frog contains 10 picograms of DNA during G1, then this cell will have 20 picograms of DNA before the product of the first meiotic division, and will have 10 picograms at the begining of the meiosis 2 (i.e prophase II)

Greenhouse gases absorb radiation from the and re-radiate it back toward the

Flauer [41]

Answer:

Greenhouse gases absorb radiation from the EARTH and reradiate back toward the EARTHwhich help to maintain a normal temperature range in the Earth.

Explanation:

Greenhouse gases are gases that are capable to of absorbing infrared radiations that are emitted from the Earth's surface and reradiating back to the Earth which contributed to the greenhouse effects. Examples of greenhouse gases are carbondioxide, methane and water vapour. Others are ozones, flourinated gases, nitrous oxides e.t.c.

The green house gases has lead to climate changes in the Earth by trapping heat, the contribute to respiratory diseases by smog and air pollution. Greenhouse gases concentrations are high during warm seasons and low during cold seasons.

AfilCa [17]

Polymers are made of individual subunit called monomer.

Explanation:

Polymers are lengthy chains built up of replicating molecular subunits, named monomers. The term polymer becomes from poly- (many) and -mer (part). A polymer may be a real or manufactured macromolecule composed of recurring units of a smaller molecule (monomers). The term monomer comes from mono- (one) and -mer (part).

Monomers make polymers by creating chemical bonds or confining supramolecular by a method called polymerization. Examples of polymers comprise plastics like polyethylene, silicones. Polymerization is the method of covalently bonding the smaller monomers into the polymer. While polymerization, chemical groups are failed from the monomers so that they may join together.
