The stigma of the flower must be elevated (by the style) away from the ovary to avoid self pollination or contamination. The stigma is covered with sticky substances so that pollen can easily attached themselves to it.
The unaffected carrier individual, is the one who has only mutated gene of the autosomal recessive disease.
The right answer is B and C individuals
The genes responsible for autosomal recessive (AR) transmitted diseases are localized on autosomes.
The mutated allele responsible for the disease is recessive on the wild allele; heterozygotes are healthy and the disease is expressed only in homozygotes.
Tay-Sachs disease is a neurodegenerative disease caused by a deficiency of hexosaminidase causing an accumulation of ganglioside GM2.
Answer:
Like a sperm cell, the egg contains a nucleus with half the number of chromosomes as other body cells. Unlike a sperm cell, the egg contains a lot of cytoplasm, the contents of the cell, which is why it is so big. The egg also does not have a tail.
Answer:
The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike". ( D )
Explanation:
The property of a neuron's action potential that determines the maximum firing rate is ; The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike".
The firing rate of a neuron defines the number of spikes that a neuron can produce per second and for a typical neuron that number is from 1 spike to 200 spikes per second
<span>For the answer to the question above, flowers of corn are pollinated by the wind. They are small and lightweight to allow easy pollination by the wind. They do not need to attract animals or insects and are therefore colorless and odorless.</span>
