Explain how and why different parts of a plant are sinks for the translocation of sucrose at different times of the year in a country where there are season, such as Russia
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

Explain what would happen if the leaf tissue is kept at high temperature during the process of cell isolation
Answer:
Wilting of leaves occur.
Explanation:
if the leaf tissue is kept at high temperature during the process of cell isolation the leaf will shrink because of loss of all water. Due to high, temperature the stomata will be open and water is removed in order to remove heat from the body. A time comes that all water that is present in the cell will be removed and as a result wilting of leaves occur.

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.
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

The process of mitosis deals with?
Will mark brainliest
Answer: Gametes
Explanation:
Answer:
Gametes
Explanation:
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes.
With the above paragraph one can conclude that mitosis deals with gametes.
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
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
Burning fossil fuels for energy releases harmful emissions into the air. Which health concern is most likely related to these emissions?
A) Increases in blood cancers such as leukemia
B) Increases in skin disorders from absorption
C) Increases in respiratory illnesses such as asthma
D) Increases in digestive disorders from contaminated food
Answer:
Explanation:
its either c or b sorry if it is wrong
Answer:
C
Explanation:
If the harmful emissions are being released into the air, then the most logical answer would be an increase in respiratory illnesses auch as asthma.
It cannot be B or C because they specify that the disordera come from absorption and contaminated food, respectively.
It is most likely not A either.

Polymerase Chain Reaction (PCR) technology is used for
a. DNA identification
b. DNA repair
c. DNA amplification
d. DNA cleavage
Answer:
The correct answer is c.
Explanation:
Polymerase Chain Reaction (PCR) technology is an in vitro enzymatic method that allows the amplification of a specific DNA sequence, that is, it is the DNA amplification technique by means of the polymerase chain reaction (PCR) is a technique that consists of the in vitro amplification of a specific DNA fragment. To carry out the amplification experiment, it is necessary to know, at least partially, the sequence of the fragment to be amplified (a gene, a part of a gene, a non-coding region, ...). Basically, it is about replicating the same DNA fragment over and over again and, for this, we must do in vitro what cells do in vivo to replicate their DNA. Generally, PCR begins with the denaturation or separation of the DNA double helix by heating the sample to a temperature between 94 and 96 ° C to break the hydrogen bonds that joined them, in this way each chain remains as a template for the synthesis of a new complementary strand of DNA.
