Explain why the cell membrane is the brain of the cell, as opposed to the nucleus.
Answers
Answer:
because it holds the information needed to conduct most of the cell's functions.
Cell membrane controls the transport of molecules across the cell and its external environment, Thus, it is called as the brain of the cell.
Why is cell membrane important?Cell membrane regulates most of the cellular activities through the property of selective permeability.
It is responsible for maintaining the cellular equilibrium through influx and efflux of ions and molecules.
There are various receptors present on the cell membrane which regulates the vital biochemical processes taking place in the body.
Cell membrane functions in the cell-cell recognition and cell signalling through various receptors.
Cell membrane is important in regulating body homeostasis. It offers the protective environment to the cell.
Control and regulation of activities is processed through brain.
Therefore, cell membrane is considered as the brain of the cell.

Phenylketonuria (PKU) is a genetic disease caused by the inability to break down the amino acid phenylalanine. If untreated it leads to severe mental disabilities. PKU is due to a recessive allele. Assume that the US population is in Hardy-Weinberg equilibrium with respect to this gene. In the US the PKU rate is 1 out of every 10,000 babies born. What percent of the US population have no alleles for PKU
Answers
Answer:
Therefore, 98% of the US population have no alleles for PKU
Explanation:
The Hardy-Weinberg equilibrium states that the amount of genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.
The Hardy-Weinberg equilibrium is expressed quantitatively using a mathematical equation known as the Hardy-Weinberg equation. the equation is given below:
p² + 2pq + q² = 1
also, p + q = 1
Given a pair of alleles, S and s with A dominant and a recessive
where p is the frequency of the dominant allele in the population,
q is the frequency of the recessive allele in the population,
p² represents the frequency of the (SS) dominant genotype,
q² represents the frequency of the (ss) recessive genotype,
2pq represents the frequency of the heterozygous genotype
From the given question,
q² = 1/10000 = 0.0001
q = 0.01
from p + q = 1
p = 1 - 0.01 = 0.99
p² = 0.98
Therefore, 98% of the US population have no alleles for PKU

The stems of bamboo, a tropical grass, can grow at the phenomenal rate of 0.3 m/day under optimal conditions. Given that the stems are composed almost entirely of cellulose fibers oriented in the direction of growth, calculate the number of sugar residues per second that must be added enzymatically to growing cellulose chains to account for the growth rate. Each D-glucose unit contributes ~0.5 nm to the length of a cellulose molecule.
Answers
Answer:
Approximately 6944 glucose residues are added enzymatically per second
Explanation:
Cellulose is the main structural polysaccharides in plants. It is composed of unbranched glucose monomer units linked to each other by beta 1-4 glycosidic bonds.
The cell wall and stem of plants cells are composed of cellulose fibers. They provide rigidity and support to the plant.
In the given bamboo plant, the enzymatic addition of glucose units to the growing cellulose fiber chains results in the phenomenal growth rate of the bamboo stem.
Since each glucose unit contributes ~0.5 nm to the length of a cellulose molecule, number of glucose units required for daily growth is calculated as follows:
0.5 nm = 10⁻⁹
0.3 m/0.5 x 10⁻⁹ m = 600000000 units of glucose per day
Number of seconds in a day = 24 * 60 * 60 = 86400 seconds
Number of glucose residues added per second = 600000000/86400
Number of glucose residues added per second = 6944.4 glucose molecules per second
Therefore, approximately 6944 glucose residues are added per second

Answer:
The sucrose is transported around the plant in phloem vessels. It needs to be able to reach all cells in the plant so that the sucrose can be converted back into glucose for respiration. The movement of sucrose and other substances like amino acids around a plant is called translocation .
Belowground organs of plants (e.g. roots and rhizomes) are sinks during plant growth since they cannot perform photosynthesis. Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing
