Answer:
Chitin
Explanation:
Chitin is the polysaccharide that makes up the outer exoskeleton of many insects. It is a fibrous polymer, that is made up of chains of modified glucose molecules. It is comparable in structure to cellulose, which makes up the plant cell wall. In function, it is more similar to keratin or collagen, although these are proteins.
Chitin is exclusively found in the arthropods, mollusks and fungi. It plays an important protective and structural role, giving organisms their tough outer exoskeleton or strong cell wall in the case of fungi.
The answer is D, the rate of soil erosion has increased
B. meiosis. This process randomly rearranges the pairs of homologous chromosomes in formation of the sex cells. In addition, there is crossing-over of the chromatids while the homologous chromosomes are synapsed during meiosis I.
Answer:
Ripples in water are more formally known as capillary waves, and are caused by the subtle interaction of wind and water, or the physical interaction of the water with another object.
The process which planetesimals combine with other planetesimals is called Accretion.
There are other names which refer to as accretion. For example, Accretion geology is termed as the increase in the size of a tectonic plate by addition of materials which convergent boundary.
Accretion atmosphere is termed as the process by which water vapor which is in clouds forms water droplets around nucleation sites.
Accretion astrophysics is termed as the formation of planets and other bodies through a collection of material through gravity.
