Explanation:
DNA replication is a process which produces a replica or exact copy of the DNA molecule by using one strand of the existing DNA as a template. The new strand is formed using Chargaff rule which states that purine binds pyrimidine that is adenine(A) will bind to thymine (T) and guanine (G) will bind to cytosine (C).
Transcription is a process which produces an mRNA molecule from one strand of DNA molecule. The mRNA acts as a messenger molecule which is formed with the same Chargaff rule except for a different nitrogenous base "uracil". In mRNA uracil (U) will bind complementarily to adenine (A) instead of thymine.
The translation is a process which synthesizes the protein by reading the bases of mRNA in the triplets called 'codons". These codons code for a specific amino acid which bond to each other via peptide bond and form protein.
Adenine binds to the thymine by a double hydrogen bond and guanine binds to the cytosine by a triple hydrogen bond. But in RNA Adenine binds to the uracil.

How does the acidity of soil affect flower growth?
Soil pH can affect plant growth in several ways. Bacteria that change and release nitrogen from organic matter and some fertilizers operate best in the pH range of 5.5 to 7.0 making this the optimum pH range. Plant nutrients leach from the soil much faster at pH values below 5.5 than from soils within the 5.5 to 7.0 range. In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. PH can also affect the structure of the soil, especially in clay soils. In the optimum range clay soils are granular and easy to work with. However, if the soil is either extremely acid or alkaline clay, soils tend to become sticky and hard to cultivate.
A pH soil test will tell you whether your soil is within the optimum range or whether it will need to be treated to adjust the pH level. Although the optimum range is 5.5 to 7.0 some plants will grow in a more acid soil and some at a more alkaline level.
PH is not an indication of fertility, but it does affect the availability of fertilizer nutrients. The soil may contain adequate nutrients yet plant health may be limited by an unfavorable pH level. On the other hand, builder’s sand, which is devoid of nutrients, may have optimum pH for plant growth.

What does excessive algae on water cause?
When algae cover a river surface, it causes depletion of oxygen in water. This is known as____
Excessive algae on water causes depletion of oxygen in the water, a process known as eutrophication. This occurs when excess phosphorus and nitrogen from fertilizer runoff and sewage lead to the growth of algae, which depletes dissolved oxygen and results in the death of aquatic organisms.
Explanation:Excessive algae on water causes depletion of oxygen in water. This is known as eutrophication. Excess phosphorus and nitrogen from fertilizer runoff and sewage enter aquatic ecosystems and lead to the excessive growth of algae. When the algae die and decompose, it depletes dissolved oxygen, causing the death of aquatic organisms like fish and shellfish. This process is responsible for dead zones in lakes and rivers and massive fish kills.

How do animals store energy
Answer:
Animals store their glucose subunits in the form of glycogen, a series of long, branched chains of glucose.
Explanation:
ANSWER:
Animals store their energy in glycogen form in the body. This energy has been stored in the body for later use to perform the various life functions.
EXPLANATION:
Animals obtain their energy from the food they take in so that the various metabolic processes of the body can be performed. When animals eat food, the glucose present in food is broken-down by "cellular respiration" into an energy molecule known as ATP. When "excess ATP and glucose" are present, these are converted to glycogen by the liver and stored in the body for later use.U1:51:51

1. Do you think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved? Why or why not? Think about your opinion and then back it up with at least one fact. (10 points) APEX
Answer:
Yes, I agree that the discovery of DNA model by Watson and Crick took help from the work of many other scientists which were not credited with the discovery as much as both of them were credited.
Explanation:
One of the major breakthroughs made in the discovery of DNA structure was the work of a female scientist, Rosalind Franklin who did X-ray crystallography according to which DNA was helical in shape. Watson and Crick took strong support from this theory and proved that DNA was helical in shape. However, she was a perfectionist and she had not published her work yet while the Watson and Crick were fast enough to do so. Before that Watson and Crick while working independently formulated incorrect DNA models in which bases were placed outside while phosphate groups were outside. However, Rosalind Franklin's work was of substantial help to both of them. There was another colleagues of Franklin, Maurice Wilkins who was working with Franklin in doing X-ray studies. n 1962 Watson, Crick, and Maurice Wilkins were jointly honored with the Nobel Prize in medicine for their model of DNA in 1953 but she was not nominated for Nobel price because it could only be shared by three scientists maximum and Franklin was died by that time too.
Therefore, i think it was not fair with Franklin that she never received the credit of the work which she did tirelessly and which became basis of modern DNA model.
Hope it helps!
No, it is not fair that Watson and Crick were only credited with the discovery of the DNA model.
What is Watson and Crick's model of DNA?Watson and Crick proposed a model of DNA in 1953 which is semi-conservative in nature. This model of DNA has a double helix that is bound together with the help of units known as bases.
During the time of Watson and Crick, Erwin Chargaff proposed the rule of base pairing which is also seen in Watson and Crick's model of DNA. According to him, the amount of adenine is always equal to the amount of thymine, and the amount of guanine is always equal to the amount of cytosine.
[A] = [T] and [G] = [C]

what physical traits were favored in the peppered moth species after the Industrial Revolution
Their skin color was dark which made the moths blend in. During the Industrial Revolution, the soot from factories caused the trees to become black. The light colored moths became easier to kill because they could not blend into their environment.
Answer:
Dark Skin Color
Explanation:
After the industrial revolution, the tree trunks got covered with dark soot and the lichens present on these tree trunks were killed. Under these polluted conditions, the dark-colored moth could blend themselves easily with soot-covered tree trunks. Hence, these dark-colored moths exhibit better survival and reproductive rate than the light-colored moth population.
So, natural selection favored light skin color after the industrial revolution.

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angles of the pentagon are equal, which expression represents the measure of two angles?
2x2(20 – 32x + 25x2)
2(8x2 – 13x +10)
5x2(8x2 – 13x + 10)
5(3x2 – 8x + 5)
Answer:
2(8x^2-13x+10)
Explanation:
There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.
Let's let A represent the measurement of one of the those angles in our pentagon.
The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.
But we are also given that this equals 40x^2-65x+50.
So that means 5A=40x^2-65x+50.
If we divide both sides by 5 we can find what one of our angles is in terms of x. So let's do that A=8x^2-13x+10.
So we want to know the sum of two our angles, we want to know what is A+A or 2A. 2A=2(8x^2-13x+10). To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

The spores release from the gametophyte
The gametophytes grow directly from the sporophyte
The spores release from the male cones
I NEED HELP ASAP
Answer:
The gametophytes grow directly from the sporophyte - third choice
Answer:
The correct answer is The gametophytes grow directly from the sporophyte.
Explanation:
Conifers are a group of plants that belong to what is called Pinophyta.
They abound in quantity in cold areas although many different types of this plant can also be found in tropical areas.
They are formed by live gemnosperm plants, this means that their seeds do not form in closed cavities but are "naked". These seeds are evergreen, this means that their leaves will not fall throughout the year and usually live for more than two years or produce other seeds again.
Gametophytes are haploid plants that are usually located in or below the soil and are responsible for producing gametes.
These grow directly from the sporophyte, which is the phase in which a plant reproduces by spores.
So we can say that the correct answer is The gametophytes grow directly from the sporophyte.
What was the purpose of mendel’s experiments with dihybrid crosses
Final answer:
Mendel's experiments with dihybrid crosses were conducted to test the hypothesis of independent assortment. He crossed pea plants with different pairs of traits to determine if these traits are inherited together or independently. The results showed that traits segregate independently during sex cell division, leading to Mendel's law of independent assortment.
Explanation:
Mendel's experiments with dihybrid crosses had the purpose of testing the hypothesis of independent assortment. By crossing pea plants with different pairs of traits, such as yellow round seeds and green wrinkled seeds, Mendel was able to determine if these traits were inherited together or independently.
The results of his dihybrid crosses showed that traits segregate independently during sex cell division. This led to the formulation of Mendel's second law of inheritance, known as the law of independent assortment.
