Answer:
Plants and animals took up different evolutionary pathway millions of years ago.
In the prebiotic earth, the CO2 levels were insanely high, and the solar input was quite high due to which the initially evolved cells were photosynthetic , so that they can harness the solar energy, and because they need a carbon source, they relied on the Carbon from CO2.
In this process, the atmospheric gaseous content changed, as predecessors of plants gave out Oxygen over millions of years.
Gradually , the atmosphere was now oxygen rich and hence predecessors of animals evolved a mechanism to utilise this oxygen , and as a byproduct started releasing CO2.
Over the next years , these two diverse groups specialised and hence , became increasingly different.

Answer:
<h2>option b exothermic </h2><h3>explained here </h3>
Explanation:
Chemical reactions that release energy are called exothermic. In <u>exothermic</u><u> </u>reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. ... Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

High-altitude environments present a number of physiological challenges for endothermic animals, as they are characterized by a lower partial pressure of oxygen (<span>) and lower ambient temperatures compared to low-altitude environments at similar latitudes. The reduced </span><span> at high altitude results in reduced oxygen loading in the lungs such that the blood may not carry a sufficient supply of oxygen to the cells of respiring tissues (</span>Bencowitz et al. 1982<span>; </span>Bouverot 1985<span>; </span>Turek et al. 1973<span>). This reduced level of tissue oxygenation can impose severe constraints on aerobic metabolism and may therefore influence an animal's food requirements, water requirements, the capacity for sustained locomotor activity, and the capacity for internal heat production.

Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is <u>polycondensation</u>, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
- <em>Hydrolysis produces the rupture of molecules, with the intervention of water.</em>
- <em>Only polysaccharides are sugars bound by the dehydration synthesis process.</em>
- <em>Only proteins consist of amino acids linked through the process of hydrolysis.</em>
Answer:
- spiders
they break down organic material that then provide nutrients for the entire food web.
- freshwater shrimps
Animals like shrimp and crabs can break the materials down to detritus. Then bacteria reduce the detritus to nutrients.
-moss
Moss is considered both a producer and a decomposer because it produces its own food through photosynthesis and helps to break down organic matter into nutrients. ... In the forest, moss carpets the floor and fallen organic matter such as rotting logs. The moss helps to decompose the logs and recycle the nutrients.
