Answer:
DNA
DNADNADeoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.
2) (i) A pentose sugar is a monosaccharide with 5 carbon atoms. Pentose sugars are the deoxyribose sugars, which are part of nucleotides in DNA
(Ii) a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H ₃PO ₄. The phosphate or orthophosphate ion [PO ₄]³⁻ is derived from phosphoric acid by the removal of three protons H⁺
Formula: PO₄³⁻
Molar mass: 94.9714 g/mol

Beilstein Reference: 3903772
Conjugate acid: Monohydrogen phosphate
Gmelin Reference: 1997
(III) Nucleobases, also known as nitrogenous bases or often simply bases, are nitrogen-containing biological compounds that form nucleosides, which, in turn, are components of nucleotides, with all of these monomers constituting the basic building blocks of nucleic acids.
3) purine nitrogenous bases:-
Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.
pyrimidine nitrogenous bases
Pyrimidine: A nitrogenous base similar to benzene (a six-membered ring) and includes cytosine, thymine, and uracil as bases used for DNA or RNA.
The pyrimidine bases are thymine (5-methyl-2,4-dioxipyrimidine), cytosine (2-oxo-4-aminopyrimidine), and uracil (2,4-dioxoypyrimidine)
4) Explain Chargaff's rules for base -pairing
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C ) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
5)Identify what objects/colors you used for your DNA Model
The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
6)Twist your model and explain how it is a helix
Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups.
The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.

Answer: An enzyme that copies DNA to make a molecule of RNA is RNA polymerase.
Answer:
RNA polymerase
Explanation:
RNA polymerase has many important roles inside of an organism and is a very complex enzyme. One of the most common roles "RNA polymerases" has, is that it is able to copy DNA to then make an RNA molecule. Another common role the RNA polymerase has, is that it helps maintain the organism's metabolism. Which means the enzyme itself helps the chemical processes within an organism be completed in order to keep that organism from dying.

Explanation:
In the previous question, you used the Hardy-Weinberg equation to determine the frequencies of the genotypes for HH, Hh, and hh, given gene frequencies of H = 0. 2 and h = 0. 8. These frequencies were: HH = 0. 04 Hh = 0. 32 hh = 0. 64 Now, determine the expected numbers of each organism in the population (total size = 150): Number of HH = Number of Hh = Number of hh =.
The expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.
What is the Hardy-Weinberg equation?The hardy-Weinberg equation is a mathematical equation used to calculate the genetic variation of a population at equilibrium.
The given frequencies are HH = 0.04
Hh = 0.32
hh = 0.64
So, the percentages are HH = 4%, Hh = 32%, hh = 64%.
The total percentage will be (4 + 32 + 64 = 100)
The total size is 150
Now,
The number of HH genotype is 0.4 × 150 = 60
The number of Hh genotype is 0.32 × 150 = 48
The number of hh genotype is 0.64 × 150 = 96
The total is 6 + 48 + 96 = 150
Thus, the expected number of each organism in the population is HH = 60, Hh = 48, hh = 96.

(WILL GIVE BRAINLIST) A student investigated the effect of root space on plant growth. The student grew two groups of plants of the same variety. Both groups received the same amount of water and sunlight and grew in the same type of soil. The plants in Group A were grown in cube-shaped containers that were 3 centimeters deep. The plants in Group B were grown in cube-shaped containers that were 10 centimeters deep. The table shows the student's observations (picture provided). What was the effect of root space on plant growth based on the student's investigation? Use the data from the table to support your answer. Explain how you would know whether this effect was likely due to environmental or genetic factors.
Answer:
it goes up 2 in the second collum and then plus 1 plus 2 plus 2 plus 4 plus 4
Explanation:
The effect of root space on plant growth is significantly demonstrated by the student who infers that the plants in Group B grown in cube-shaped containers were 10 centimeters deep and obtained high growth as compared to other plants.
What is this growth of root called?Roots grow downward, or towards the center of Earth, and away from light. These responses to external stimuli are called tropisms. Plants' growth response to gravity is known as gravitropism; the growth response to light is phototropism.
The experiment is well-designed and is able to directly infer the effects of root space limitations without having to account for other factors. We can assume that the limited root space will in turn limit the extent to which a plant can grow. This is because plants need larger and deeper roots to support extended growth. Therefore, the plants in group B will grow smaller than those in group A.
Therefore, the effect of root space on plant growth is significantly demonstrated by the student who infers that the plants that have deeper soil will grow high.

Sugars are _____ carbohydrates and starches are _____ carbohydrates
Answer:
sugars are simple and starches are complex.
Explanation:
hope this helps, mr cleann
Sugars are simple carbohydrates and starches are complex carbohydrates.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats. Glucose is created by your body's breakdown of carbs.
Your body uses carbohydrates as its primary energy source to power your kidneys, heart, brain, muscles, and central nervous system.
As an illustration, fiber is a type of carbohydrate that promotes healthy digestion, makes you feel full, and lowers blood cholesterol levels.
Carbs come in two primary categories: Fructose, glucose, and lactose are examples of simple sugars (or carbs), and they are also present in wholesome whole fruits.
Starchy vegetables, whole grains, rice, breads, and cereals are examples of foods that include complex carbohydrates (also known as starches).
Thus, starches are a type of complex carbohydrate, whereas sugars are a simple carbohydrate.
