Answer:
Explanation:
Mitosis takes place in somatic cells of the body while the meiosis takes place in the germ cells. The mitosis is the equational division while the meiosis is reductional division.
The meiosis has 2 cell divisions i.e. meiosis I and meiosis II. The mitosis is a single division.
The pairing between the homologous chromosome/synapsis occurs in meiosis. It is not found in mitosis.
During the pachytene stage of meiosis, crossing over takes place. The homologous chromosome exchanges its genetic materials in crossing over.
In mitotic cell division, the chromatids do not exchange their genetic material.
The chromosome numbers are always the same as the parent cell in the mitotic division. In meiosis, the number of the chromosome turns to half of their parent cells.
There are 4 haploid chromosomes/tetrads forms at the end of meiosis. In meiotic division 2 chromosomes form from the parent cells.
Answer:
Some of the energy released by ATP hydrolysis is used in muscle movement while the rest is lost as heat.
Explanation:
According to the second law of thermodynamics, when energy is transformed from one form to another, some energy is used to perform work while the rest is lost as heat to the surroundings. The energy heat energy lost to the surroundings cannot be used to perform functions.
According to the given information, the chemical energy released from the breakdown of ATP is converted into mechanical energy during the movement of a muscle. However, some of the energy released from ATP is lost as thermal energy and is not available to serve in the movement of muscles. This loss of part of the energy as heat during muscle movement explains that the process follows the second law of thermodynamics.
Answer:
D. Polysaccharide
Explanation:
A polysaccharide is a type of carbohydrate.
Answer:
It is the biological concept of species
Explanation:
In 1970 Mayr stated that "species are formed by groups of potentially intercrossing populations that are reproductively isolated from others". The biological concept of species puts emphasis on existence of barriers that limit the gene flow among groups within the same species
