What are gene maps and how are they produced? Gene maps is a graph at in which it tells you what and where a chromosome is and is placed. It is created by the rate at which linked genes were separated and recombined which could then be used to produce a “map” of distances between genes.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.
Answer:
Living things use structural strategies and behavioral strategies that increase their chances of reproduction.
Living things do so to reach the reproduction goal that is to pass genes on to offspring. For example: the pouch of a kangaroo, a frog croaking a mating call, and colorful petals of flower etcetera helps in increasing mating chances so that their genes can be followed to the generation.
Answer:
Filip's medical report, diagnosed with Alzhaimer's, may reveal a diminished production of acethylcholine.
Explanation:
Alzhaimer's disease is a neurodegenerative condition that causes immediate memory loss, behavioral changes and cognitive impairment, due to neuronal alterations and atrophy.
The neurotransmitter acetylcholine —related to neuronal transmission and body movement— may experience a decrease in its production leading to Alzheimer's, according to the cholinergic hypothesis.
Many therapies and treatments at present are based on the use of drugs to correct the acetylcholine deficit.
Regarding other options:
- <em>Dopamine: alteration or deficit is related to Parkinson's disease.</em>
- <em>Gamma aminobutyric acid (GABA): deficiency is not common and is related to a type of congenital and infantile neuropathy.
</em>
- <em>Serotonin: deficit of this neurotransmitter can lead to depression and psychological disorders.</em>
