Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another. true
devlian [24]

The given statement "Decreasing the rate of gene flow between two populations is likely to make the populations more different from one another." is False.

<h3>What is gene flow?</h3>
  • Gene flow refers to the processes by which genes are transferred from one group to another.
  • Gene flow, which is a term used more frequently in anthropology, refers to the allelic change brought on by human movement.
  • Gene flow would reduce the isolation that could lead to speciation by increasing population similarity and reproductive kinship.
  • Gene flow significantly slows down speciation by recombining the gene pools of the groups and therefore repairing the growing variations in genetic variation that would have otherwise resulted in full speciation and the creation of daughter species.

If a DNA sequence is A-T-G-A-C, write the sequence of base pairs that would pair with it.
denis23 [38]

Answer:

T-A-C-T-G

Explanation:

Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.

Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.

What is one effect of methane gas being released into Earth’s atmosphere? *
bogdanovich [222]

Answer:

An increase in the amount of greenhouse gases in the atmosphere

Liquid; gas

Lacking oxygen

To decrease the temperature in the compost pile

Explanation:

1.  Methane is one of the greenhouse gases. When these gases are released into the atmosphere, they increase the temperature of the earth surface because they trap heat within the earth. Other examples are carbon dioxide and water vapor.

2. Evaporation is a phase change from liquid to gas. During this process, heat is supplied to a liquid. When the molecules of the liquid gain enough energy, they then begin to break off into gaseous form. The reverse process of evaporation is condensation.

3.  Anaerobic is a process that lacks oxygen. Aerobic processes are carried out with the availability of oxygen.  

4. The reason why compost should be regularly mixed is to decrease the temperature in the compost pile. Portions of the compost can have a higher temperature than other parts. Therefore, mixing the compost will help to redistribute the heat in the compost.

Where do the respiratory and circulatory systems meet?
zlopas [31]

Answer:

Option C. The lungs.

Explanation:

Alveolis are the air sacs in the lungs which main function is to get oxygen into your bloodstream and carbon dioxide leaves the blood.

The alveolis are located in the lungs, and it's where the respiratory and circulatory systems meet, for the reasons stated before.

Therefore, the correct option is Option C.
