Answer:

D. dehydration synthesis

Explanation:

Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).

Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.

Organism in which the embryonic blastopore becomes its anus
Anika [276]

Organism in which the embryonic blastopore becomes its anus Deuterostome

<u>Explanation:</u>

The term Deuterostome refers to second mouth. The first opening which is called blastpore becomes its anus in deuterostomes. In protostomes, this first opening will be the mouth.  The other name given to these Deuterostomes enterocoelomates. It is the enterocoely from which the   coelom of  Deuterostom starts emerging and growing.  

Chordata, Echinodermata, Hemichordata are the classes of deuterostomes:. The zygote is the one that gets developed first in  protostomes and deuterostomes.Radial cleavage occurs in deuterostom in which the division of cells lies either in parallel direction or in perpendicular direction with respect to the polar axis.

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.
