The unaffected carrier individual, is the one who has only mutated gene of the autosomal recessive disease.
The right answer is B and C individuals
The genes responsible for autosomal recessive (AR) transmitted diseases are localized on autosomes.
The mutated allele responsible for the disease is recessive on the wild allele; heterozygotes are healthy and the disease is expressed only in homozygotes.
Tay-Sachs disease is a neurodegenerative disease caused by a deficiency of hexosaminidase causing an accumulation of ganglioside GM2.
Answer:
<em>The correct option is A) The chemicals in the pesticides could run off into water sources and contaminate them, which would kill many aquatic species.</em>
Explanation:
Although pesticides can be helpful in eliminating the pests which thrive on crop plants, yet the usage of pesticides can be harmful in a number of ways. Increase in the usage of pesticides can be harmful for humans when they utilize food from such crops which is loaded with pesticides. Also, increased usage of pesticides causes the pesticides to run off in nearby rivers and lakes due to conditions such as a flood. The toxic pesticides kills the aquatic life present in that lake or river.
Answer:
Renewable Resources
Geothermal power is a form of renewable energy created by powering electrical generators with the heat of the earth and naturally occurring subterranean hot water reservoir
Answer;
-Nuclei acid
Explanation;
-Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.
-Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.
Microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes.
So from your choices most likely it will be A) ancient bacteria :)
