Answer:

Forest carbon is released when trees burn or when they decay after dying (as a result of old age or of fire, insect attack or other disturbance). A forest is considered to be a carbon sink if it absorbs more carbon from the atmosphere than it releases. Carbon is absorbed from the atmosphere through photosynthesis.

Answer:

City A

Explanation:

The temperatures are very high, but the amount of precipitation is very low. In city B, the amount of precipitation is high, meaning that it is not a desert.

What happens in the G2 phase of the cell cycle?
balu736 [363]
The Best Answer :
 <span>"G2 phase is the third, final, and usually the shortest subphase during interphase within the cell cycle in which the cell undergoes a period of rapid growth to prepare for mitosis. It follows successful completion of DNA synthesis and chromosomal replication during the S phase, and occurs during a period of often four to five hours. This far into interphase the nucleus is well defined, bound by a nuclear envelope and contains at least one nucleolus. Although chromosomes have been replicated they cannot yet be distinguished individually because they are still in the form of loosely packed chromatin fibers. The G2 phase prepares the cell for mitosis (M phase) which is initiated by prophase. 
At the end of this gap phase is a control checkpoint (G2 checkpoint) to determine if the cell can proceed to enter M phase and divide. The G2 checkpoint prevents cells from entering mitosis with DNA damaged since the last division, providing an opportunity for DNA repair and stopping the proliferation of damaged cells. Because the G2 checkpoint helps to maintain genomic stability, it is an important focus in understanding the molecular causes of cancer."</span>

What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes? Select the four corr
11111nata11111 [884]

Answer:DNA is shown to be the genetic material in bacteria and some phages.

DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed

Specific genes can be isolated and spliced into bacterial DNA, which can be inserted into a bacterial cell, and then its genetic expression is monitored.

DNA and RNA are found to be the only macromolecules in eukaryotes that consist of a set of subunits which can combine in unique sequence

Explanation:

1. Lipds is another macro molecule with different subnits  of  fatty acids and glycerol,therefore the option ( DNA is found to be the only macro molecule in Eukaryotas that has different sub units) is WRONG.

2 The   correlation of action and absorption spectra varies with different organisms DNA. e..g  in viral cells  there is a wide difference between the absorption and action spectra, that is no correlation, while  some bacterial cells showed correlations. The option(For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated IS WRONG.
