Answer:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
Answer: a. True
Explanation:
Artificial human insulin is the advancement of the field of biotechnology. It is the product of recombinant DNA technology. The insulin is a hormone which is secreted by the pancreas to maintain the levels of sugar in the blood. But in some people the secretion of insulin can be found to be low or no insulin is produced at all these are affected by the condition called as diabetes. Thus artificial or synthetic insulin was invented to regulate the blood sugar levels. The artificial insulin is produced in the microbes like yeast and bacteria. The human gene encoding for the production of insulin is inserted into the microbial genome which produces the insulin in the microbial structure.
Answer:
Energy that is not used in an ecosystem is eventually lost as heat. Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... In each case, energy is passed on from one trophic level to the next trophic level and each time some energy is lost as heat into the environment.
