Answer:
This question lacks options, the options are:
A) transporting ions against an electrochemical gradient
B) cell-cell recognition
C) maintaining fluidity of the phospholipid bilayer
D) attaching to the cytoskeleton
E) establishing the diffusion barrier to charged molecules
The answer is B
Explanation:
Generally, oligosaccharides are short chains of polysaccharides/carbohydrates. They make up the structure of membranes including the plasma membrane. Oligosaccharides attached to the protein content of the cell membrane to form a substance called GLYCOPROTEIN. The attached oligosaccharides functions in the ability for a cell to recognize another cell.
According to this question, if an animal whose cell is lacking oligosaccharides on the external surface of its plasma membrane, the most likely impairment would be that of CELL-CELL recognition.
A punnet square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologist to determine the probability of an offspring having particular genotype. Base on that the possible answer would be that the<span> two parents should have genotype a of something like XXi x XY where Xi is the allele for red eye colour</span>
Human
Explanation - Humans have exceeded the carrying capacity. Technology is one of the considerable factor for reducing the death or mortality rate of humans and increasing the birth rate.
Example - the medical instruments have advanced to such an extent that the patient is more likely to get cured soon unlike previous years. It has now become a major concern that the population might reach to the extent when our planet, earth will not be able to sustain us.
D. only in the nucleus. DNA or (deoxyribonucleic acid) is what makes you... YOU! All of your traits (Hair color, Eye color, The shape of your ears, Cancer risk, SKIN COLOR, etc.) But DNA is only housed in the nucleus of the cell, so the nucleus is the only place the transcription of the melanin gene could take place.
Mass spectrometry is used for protein to help build the muscle.
