Answer:
The protein is too large to simply diffuse across the phospholipid bilayer of the cell, so it uses phagocytosis to diffuse across, where it is contained in a vesicle and pinched into the cell? Credits to yahoo answer. Hope I could help sweets.
Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.
These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.
Answer:
No
Explanation:
A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).
These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.
Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.
Think about it like comparing the instructions for building a car to the instructions for building a bicycle.
Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.
It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.

Answer:
A. supplementary motor cortex; premotor cortex
Explanation:
The supplementary motor cortex, also known as the supplementary motor area (SMA), is an area of the cerebral cortex located anterior to the premotor cortex. This area (SMA) is involved in the execution of complex and rapid sequential movements (e.g., typing). Moreover, the premotor cortex is an area of the motor cortex located between the primary motor cortex and the prefrontal cortex. This area (premotor cortex) is activated during motor tasks including, among others, spatial and sensory guidance of movement.
It means that two chromosomes
have the same genes, or variations fo the
same genes at the same loci on the chromosomes. Variation
of the same gene is what makes up
alleles. Homologous chromosomes
are similar in size and structure. In
diploid organisms, each chromosome in the pair is derived from each parent.
