The correct answer is: A. minus end; dynein
Microtubules are cytoskeletal fibers that have an important role in the intracellular transport (movement of vesicles within the cell) and in the mitotic spindle during mitosis. The plus end of the microtubules extend through the periphery of the cells while the minus ends are anchored within the centrosome.
Necessary proteins for the vesicle’s movement are motor proteins:
• kinesin which is positive end directed
• dynein which is negative end directed
So, beside vesicles these proteins are also involved in organelles’ transport in opposite directions through the cytoplasm.
The hemi
metabolism<span> indicates the three distinct
stages of the life cycle of some insects: the egg, nymph, and the adult stage,
or imago. It has no pupal stage just like the complete metamorphosis that
undergoes pupal stage before turning into adult. Insects that undergo hemi metabolous metamorphosis go through gradual changes; develop from
eggs into nymphs sometimes called larvae by some entomologists, that are
similar in shape to the adults. You can
distinguish the nymphs from the adults by looking for wings. Wing buds
or wing pads may be present in late stage nymphs, but they are fixed in place
against the body and are non-functional compared to the adults whose wings are
fully developed. </span>
Answer:
The answer is carrying capacity
potential energy
you have potential energy when you're stopped. you have kinetic energy when you're moving. so as you're going down a hill, kinetic energy is increasing and potential energy is decreasing.
The statement in the given question that presents a condition of the Hardy-Weinberg principle is that random mating occurs. The correct option among all the options given in the question is option "C".
There are definitely certain
conditions under which the Hardy- Weinberg principle occurs and they are when
there is no gene flow, no mutations happen, no generic drift occurs and random
mating occurs. This principle also states a very important aspect and it is
that genotype and allele frequencies will always remain constant from one
generation to another if there is absence of other evolutionary inflrnce.
