Answer: Genetic variability is beneficial for the survival and adaptation. But a flaw in DNA Replication Control or check may leads to the death of cell or may contribute in the disease or cancer.
Explanation:
Almost every species comes with the diversified collection of genes (genome). And some of the diversity comes from the spontaneous mutation but it occurs on a very low frequency. The genes either express constitutively or occasionally for an important task like genes responsible in the generation of ATP by glycolysis, tricarboxylic acid cycle, electron transport chain etc. While some of the genes are inducible that is only activated in a response to an external stimuli. Genetic variations in inducible genes might account for the adaptability or negligible change in a species genetic expression but genetic variation in constitutive or house keeping genes leads to cancer cell formation or even cell death. like mutation occur in p53 genes dysregulate the cell cycle or mutation occur in DNA polymerase enzyme that is responsible for the incorporation of NTPs (nucleotide tri-phosphates) according to wobble base pairing rule in order to make a complementary new strand from the old or parent strand, will eventually leads to cause mutations ultimately results in cell death or cancerous cell formation.
Answer:
C pharas describes best
Explanation:
Biogeochemical cycle is the cycle through which chemical substance move from biotic (biosphere) and abiotic (lithosphere,hydrosphere,atmosphere) campartment of the earth
Answer:
c) degree of myelination of the axon
Explanation:
The myelin sheath covers many axons in central nervous system (CNS) ( by oligodendrocytes) and in the peripheral nervous system (PNS) (by Schwann cells). Their function is to insulate axons and to increase the speed at which information travels from one nerve cell to another.
Nerve conduction velocity is specific to each individual and depend on the level to which that axon is myelinated, but also on an axon's diameter.
Answer:
The important structure the producer posses is "chloroplast".
Explanation:
Chloroplasts work to alter light energy of the Sun into sugars that can be utilized by cells. The complete procedure is named as photosynthesis and it all depends on the slight green chlorophyll particles in chloroplast respectively. Plants are the foundation of all life on Earth. They are classified as the producers of the world. Photosynthesis is the procedure by which plants, some bacteria and some protistans use the energy from sunlight to harvest glucose from carbon dioxide and water. This glucose can be transformed into pyruvate which issues adenosine triphosphate (ATP) by cellular respiration. Oxygen is also designed.
