Answer:
Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).
Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.
Explanation:
Answer:
Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.
Evolution is the cycle by which current creatures have dropped from old progenitors. Evolution is liable for both the surprising similitude we see over all life and the astonishing variety of that life.
Explanation:
Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.
It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.
Answer:
1 mole
Explanation:
A mole is 6.022*10^23 units
Answer:
Large population
Random mating
No evolutionary mechanisms (mutations, genetic flow,, genetic drift, natural selection)
Explanation:
According to Hardy-Weinberg model, allele frequence (or genotype frequencies) will remain constant through generations in the absence of disturbing factors, evolutionary mechanisms. Such constant population is in Hardy-Weinberg equilibrium (no evolving population). Factor that can disturb equilibrium of the population are nonrandom mating, mutations, gene flow, natural selection, genetic drift.
According to Hardy-Weinberg model:
p2+2pq+q2=1 (p+q=1)
p2 is the frequency of dominant homozygous genotype
2pq is is the frequency of heterozygous genotype
q2 is is the frequency of recessive homozygous genotype
Answer:
Matter cycles throughout the environment in both the oxygen and nitrogen cycle. The nitrogen cycle involves nitrogen-fixing bacteria, lightning, and decaying organic matter. The oxygen cycle involves carbon dioxide and oxygen gases as well as the process of photosynthesis.
