Answer:
By looking for amino acid sequence differences between species, scientists can infer how closely or distantly related two species are in evolutionary time.
Explanation:
have a great day :)
The answer is true. blood flow to many different organs to meet the increased metabolic needs of the tissues.
Answer:
Natural selection by directional selection, was the driving force of evolution at work. The purple flowers parents were able to withstand the selective pressure and therefore emerged from completions with other flowers from previous generation, thus their dominance follow directional selection. This was the trait inherited by their offspring, the dominant purple
The gene pool of purple flower will be large; because of dominance in expression with each successive generation in both homozygote and heterozygote state, and therefore higher frequency of expression compared to the white flowers.
The frequency of allele depends on the rate expression of the allele in the population. Thus, the dominant purple flowers have high frequency of expression compared to the recessive white flowers which can only express itself in homozygote recessive state
Answer:
The correct answer is d amyloid plaques and Tau neurofibrillary tangles.
Explanation:
Alzheimer"s disease is one of the most devastating neurodegenerative disease occur in human.
Alzheimer disease is caused due to the accumulation of amyloid precursor protein or misfolded proteins in the brain resulting in the formation of neurofibrillary tangles which ultimately leads to degeneration and loss of most of the vital functions of neurons.
This is called Osmosis.
hope this helps!
