In vertebrates, motor neurons release acetylcholine (ACh), a small molecule neurotransmitter, which diffuses across the synaptic cleft and binds to nicotinic acetylcholine receptors (nAChRs) on the cell membrane of the muscle fiber, also known as the sarcolemma.
Answer:
Gas exchange between tissues and the blood is an essential function of the circulatory. The air contains oxygen that crosses the lung tissue, enters the bloodstream, and the alveoli are in direct contact with capillaries of the circulatory system. As water flows over the gills, oxygen is transferred to blood via the veins.
Explanation:
Answer:
we need one for somatic cell division and one for sexual/reproductive
Explanation:
mitosis is used for somatic (body) cells like when you get a cut and then meiosis is used to reproduce gametes and make embryos
Answer:
In a cross between two black-haired guinea pigs, 20 offspring are born. If both parents were heterozygous, probability would predict that approximately 1 out of 20 offspring would have brown hair
Explanation:
The two parents crossed were heterozygous dominant black coat color, after crossing 75% gives dominant black color coat while 25% gives only brown coat color homozygous
RFLP, AmpFLP are the two techniques which is used to create DNA profile
Explanation:
<u>RFLP technique: </u> RFLP technique stands for “Restriction Fragment Length Polymorphism”. It is molecular method of genetic analysis which allows to identified based unique pattern of restriction enzyme where DNA is cutting in specific regions. It requires large amount of sample. The costing is very high
<u>AmpFLP: </u>The AmpFLP stands for amplified length polymorphism. It is PCR based tool. Firstly, it uses as restricted enzyme. It is cheaper than RFLP technique. It is used as genetic engineering
