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%How does the hardness of a rock impact their ability to erode?

Describe the relationship between genes, proteins, chromosomes, and cells.
Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Explanation:
Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
What are chromosomes?Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
The term chromosome comes from the Greek words for colour (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colourful dyes used in research. The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones.
Without such packaging, DNA molecules would be too long to fit inside cells.

Describe: Four examples of renewable resources are featured in the Energy Conversions Gizmo. These resources are produced all the time, so they will not run out. Read about each energy source, and then explain how each is produced in your own words.
Answer:
Explanations below
Explanation:
A. Wind power:
In the principle of wind power energy, the wind turbine used in the process has blades that look like propeller. When the wind turns the blade around a rotor, it spins a generator and electricity is being generated.
B. Water power (also called hydroelectricity):
The hydro power process is similar to that of the wind power. At the hydropower plants in different localities, one would notice the flow of water through a pipe, which turns the blades in the turbine, to spin a generator and electricity is being produced.
C. Solar power:
In solar power generation, solar panels are used. The required solar energy is produced when sunlight strikes the solar panels and that converts the solar power into electricity that can be used.
D. Ethanol:
Ethanol is a renewable biofuel which can be made from different things such as grasses, corn cobs and stocks, rice straw, sawdust, and wood chips. During the process, yeast is used to ferment the start and sugars in the corn and sugar cane. The starch is fermented into sugar which can also be fermented into alchohol [ethanol].

When is osmosis used by
cells to move water across a selectively permeable
membrane?
A. Osmosis is used by cells when large molecules pass freely across the selectively permeable membrane.
B. Osmosis is used by cells to create equilibrium when large molecules can't pass through the membrane.
C. Osmosis is constantly in process inside of a cell, regardless of equilibrum.
Answer:
B.
Explanation:
Osmosis moves water from the part of the membrane with less solutes to the part with more solutes. This will continue until the cell or whatever it is reaches equilibrium.
Tell me one thing you know about replication.
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Complete a model to explain the molecular events occurring at each stage of this reaction profile. Rank the stages from the first to the last one.
The substrate molecules are entering the cells, so no product is made yet As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
There is sufficient substrate, so the reaction is proceeding at a maximum rate
Section A Section D
Answer:
The substrate molecules are entering the cells, so no product is made yet.
There is sufficient substrate, so the reaction is proceeding at a maximum rate
As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
Explanation:
First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.

The rate limiting reaction of aerobic respiration involves the phosphorylation of __________ by the enzyme _______ . The rate at which this enzyme makes product is ___________when ATP levels rise because the molecule ___________binds to an _________ site on the enzyme and acts as a(n)_________ . When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.
This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.
What is an enzyme?An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.
Factors that affects an enzymeThere are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:
The logarithmic concentration of hydrogen (pH).Temperature.Cofactors.Allosteric inhibitors.Read more on here:

Option A
WaterGenerally Water is Good for the body, But excess of water has its own adverse effect .
Sodium wash away in the blood causes hypo tonic solution in comparison to blood cell.
Therefore, on the count of excess water entering into to the blood cells, the cells tends to rise or swell as water enters into them.
Cells swell as water moves into them.
