Horses are much larger today than their two-foot tall ancestor, mesohippus. Geologists believe the change in size was the result
Darina [25.2K]
The answer is: <span>larger horses have longer legs.

</span>The ancestors of horses lived in the forest, where they could hide from the predators. But, with the first steppes, they could be spotted by the predators. Horses had to adapt in order to survive. Thus, their legs became longer through time so horses could run faster to escape predators.<span>

1. Define Chemosynthesis?

the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.

2. List some organisms that undergo Chemosynthesis?

Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic.

3. Which organisms conduct photosynthesis?

Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

4. Define photosynthesis

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

5. Type out the chemical equation of photosynthesis?

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

a. The links joining monosaccharide residues in a polysaccharide are called ____________________ bonds.
aev [14]

Answer:  Glycosidic bonds.

Explanation:d

Glycosidic bonds are covalent bonds that  join monosaccharides or longer glucose chains to other monosaccharide or carbohydrates to form disaccharides, oligosaccharides and polysaccharides and are named according to the type  of the atom present on the second carbohydrate to be linked. The bond is usually  formed between the hemiacetal of  the first carbohydrate and the functional  group on the second molecule which could be Oxygen-, Nitrogen-Sulphur -, and Carbon -glycosidic bonds.

Examples of  Polysaccharides are Cellulose Starch , Glycogen  formed by the linkage of many long residue monosaccharides connected through  glycosidic bonds.
