Answer:
It results in a higher concentration of molecules on one side of the membrane.
Explanation:
Active transport is the transport of molecules up the concentration gradient. This means that molecules are going from low density to high density. This is the opposite of natural diffusion. So, it requires ATP to move the molecules this way. Diffusion normally occurs to maintain homeostasis and an equal amount of concentration on both sides of a membrane. But, with active transport, since molecules are moving up the gradient, the opposite happens and the concentrations are unequal.
Answer:
may be the answer is A or D
Answer:
The correct answer is an allele.
Explanation:
The variant form of a gene is termed as allele.Some genes exits as various different forms at a specific position on a chromosome also called genetic locus.
Humans are diploid organism.The diploid nature is due to the presence of two allele at each genetic locus among them one allele is inherited from paternal origin and the other allele is inherited from maternal origin.
The given statement is True.
Visual Receptors: Rods and cones are the two types of cells present in the retal part of eye which works as a visual receptors which establishes a synaptic network involving neurons which connects the receptors to brain and help us in visualizing. However loss of neurons in the retina because of any kind of physical or biological damage permanently cuts the connection of receptors with brain and it cannot be replaced naturally.
Hearing receptors: Inside the ears there is a small structure known as cochlea which contains the organ of corti which further contains the hair cells [sensory cells] working as hearing receptors but research till date concludes that mammalian cochlear hair cells do not regenerate, either spontaneously or after damage.
Taste receptors: The small little bumbs present of our tongue are known as papillae whioch functions as taste receptors as they contain taste buds. Scientifically there taste buds die off and regenerate every few weeks.
Olfactory receptors: These receptors keep on replacing due to continuous differentiation of basal cells which develop and are capable of restablishing the connection with Central nervous system.
