Explanation:
Answer:
TRUE
Explanation:
Fragile X syndrome is a disorder in which nucleotide repeats will result in increase in copy number which will make the threshold unstable < it is basically a trinucleotide repeat disorder
Answer:
To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.
Explanation:
- Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
- The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
- When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
- By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
- By using these techniques, biologist have found that <em>homo sapiens</em> are 99% have their similarities with chimpanzee
- Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
Answer:
a gated sodium channels open and sodium ions flood into the cell
<span>here are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation. Glycolysis literally means "splitting sugars.". Glucose, a six carbon sugar, is split into two molecules of a three carbon sugar. Glycolysis takes place in the cell's cytoplasm.</span>
