If a strand of DNA has 17% T,what percent will
be G? C? A?
Answer:
If a DNA strand has 17% Thymine (T) the percentage of the other nitrogenous bases will be 33% of Guanine (G), 33% of Cytosine (C) and 17% of Adenine (A), according to Chargaff's law.
Explanation:
The percentage of nitrogenous bass in a DNA strand can be established by knowing the percentage of one of the bases present in the molecule, in this case knowing that Thymine corresponds to 17% of bases.
DNA has the nitrogenous bases adenine (A), guanine (G), thymine (T) and cytosine (C). The bases of one chain are matched with the bases of another, according to the complementarity of the nitrogenous bases, where:
Adenine is complemented with thymine A=TGuanine is complemented by cytosine G≡CAccording to this, DNA molecule there is as much T as A, and an equal amount of G and C, and the percentages of nitrogenous bases can be calculated according to Chargaff's rule.
Chargaff deduced that in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of the bases.
Calculating the percentages, according to the law of the base pair, if in a DNA chain there is 17% of T, in the molecule there is:
A = 17 %C = 33%T = 17%G = 33%Total ..... 100%Plasma membranes allow certain materials to pass through them. Investigate how this property contributes to homeostasis.
Answer:
this
The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in.
or this
A major role of the plasma membrane is transporting substances into and out of the cell. The plasma membrane is selectively permeable, allowing only certain substances to pass through. ... Cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

How do the daughter cells compare genetically to the original parent cell after mitosis?
Answer:
after mitosis there are two daughter cells, which are genetically identical to the parent cells.
Explanation:
The daughter cells are identical to the parent cells because the cell copies/ replicates its chromosomes. Then it splits the chromosomes equally so that each daughter cell has a complete set of chromosomes.
Parent cell give rise to daughter cell being genetically identical because of it replicates the DNA, so after mitosis, both daughter cell is genetically identical to the parent cell.
How daughter cell is genetically identical to the parent cell?Mitosis results in the formation of two identical daughter cells, each with the same number of chromosomes as the parent cell.
Meiosis, on the other hand, produces four distinct daughter cells, each with half the amount of chromosomes as the parent cell. Because DNA replicates to complementary to other DNA strands.
The mature cell that is undergoing cell division is known as the parent cell or the mother cell, and the new cells that emerge at the conclusion of the cell division are known as daughter cells.
Therefore due to DNA replication daughter cell is genetically identical to the parent cell after mitosis.

Which of the following statements is true?
a) only males can get an X-linked. disorder.
b) only females can get an X-linked disorder.
c) only males can get a Y-linked disorder.
Answer:
The answer is a
Explanation:
X-linked disorders result from mutated genes on the X chromosome. Males, who have only one X chromosome (i.e., they are hemizygous), will fully express an X-linked disorder. On the other hand, females, who have two X chromosomes, will be carriers of the defect in the majority of cases, and so they are usually asymptomatic.

PLSS HELP how is gene knockout similar to gene sequencing?
Answer:
Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.
Explanation:
In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.

A student is investigating how substrate concentration affects the rate of anenzyme-catalyzed reaction. Which threevariables should be kept constant in the setup of thestudent’s investigation? Select all three variablesA. temperature of the reactionB. amount of enzymeC. amount of substrateD. amount of productE. pH of the reaction
Answer:
A. temperature of the reaction
B. amount of enzyme
E. pH of the reaction
Explanation:
Temperature should be kept constant because enzymes operate at different activity rates depending on the temperature. The same goes for the pH as well with different enzymes having different optimal pH levels.
The amount of enzyme should be kept constant as well because different concentrations of enzymes can determine how fast the reaction will occur.
Essentially anything that could affect enzyme activity apart from substrate concentration should be kept constant.
4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.
Answer:
Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.
The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.
Explanation:
The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.
The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.
When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.
