Answer:
1. Probability is 50% or 1/2
2. a) Genotypic ratio= 1 AA: 2Aa : 1aa
b) Phenotypic ratio = 3 normal pigment : 1 albino
3. Monohybrid cross
Explanation:
This question involves a single gene coding for pigment in humans. The allele for normal pigmentation (A) is dominant over the allele for albinism (a).
According to this question, if two heterozygous parents (Aa) are crossed i.e. Aa × Aa. The following proportion of offsprings will be produced:
AA, Aa, Aa, and aa
- Hence, the probability of having a heterozygous offspring is 2/4 or 1/2 or 50%
- Genotypic ratio= 1 AA: 2Aa : 1aa
Phenotypic ratio = 3 normal pigment : 1 albino
c. This type of cross is called MONOHYBRID CROSS because it involves a single gene
What molecule is removed during dehydration synthesis? *
a. Water
b. Carbon dioxide
c. Sugar
d. Carbon
During dehydration synthesis, water molecule gets removed. The correct option is a.
What is dehydration?A dehydration reaction in chemistry is a chemical process in which the reacting molecule or ion loses water. The opposite of a hydration reaction, dehydration reactions are frequent processes.
"Chemical processes known as dehydration reactions are those in which a water molecule is removed from the reactant molecule. Dehydration synthesis is the process of combining two compounds while removing water molecules.
These kinds of reactions can assemble and disassemble nucleic acids, proteins, and carbohydrates, however the monomers in each case vary.
Many polymers are made by dehydration processes as well. Another illustration is the transformation of alcohols into ethers.
Thus, the correct option is a.

Scientific theories can change when new evidence is discovered and is supported and accepted widely. Which statement can possibly create a change in the cell theory?
a. A scientist discovers a new living organism with different cells.
b. A scientist discovers a new living organism with cells but no tissues.
c. A scientist discovers a new living organism that has no cells.
d. A scientist discovers a new living organism that has cells that work separately.
Answer:
c. A scientist discovers a new living organism that has no cells.
Explanation:
The cell theory is a widely accepted and globally recognized theory of living things. It was proposed in the 1830's by the collective effort of three scientists namely: Mathias Schleiden, Theodor Schwann and Rudolph Virchow. The cell theory is made up of three components as follows:
- All living things are made up of one or more cells.
- The cell is the basic and fundamental unit of life.
- All living cells comes from pre-existing cells.
According to this question, a new evidence that can possibly create a change in the cell theory is if a SCIENTIST DISCOVERS A NEW LIVING ORGANISM THAT HAS NO CELLS because all living organisms have been said to be made up of cells in the cell theory.
Transpiration is the evaporation of water from the surface of a plant. Explain.
Answer:
Transpiration is the loss of water from a plant in the form of water vapor. Water is absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants, less than 5% remains in the plant for growth.
4. Which evidence did Darwin NOT use to support his theory of evolution?

3. The cell below is currently in Metaphase I. Draw the four resulting cells after the original cellgoes through Meiosis. Write down the genotype above each of the new cells. (ignore
crossing over).
You will find the cell in metaphase and the draw of the gametes in the attached files
Answer:
Gametes: RY, RX, rY, rX
Explanation:
During metaphase I, homologous pairs migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane.
During metaphase II, when the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Diploid cell) RrXY
Gametes) RY, rY, RX, rX
The alleles of each of the genes randomly migrate to different poles and combine with the allele of the other gene that migrated to the same pole.

If a population pyramid has a very broad base then what does that tell you about the population it represents?
Answer:
A population pyramid is defined as a graphical representation that shows distribution of both genders male and female in all age groups.
The base of a population pyramid represents the birth rate, so a very broad base represents the higher population of younger age children and higher birth rate.
Hence, the wide base shows higher population of younger age children and higher birth rate.

What letters represent the four nitrogen bases in DNA?
Answer:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
Explanation:
The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine).
What is base-pairing rule?According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
The bases are Adenine, guanine, guanine, cytosine, thymine, adenine the string of their base pair would be Thymine, cytosine, cytosine, guanine, adenine, thymine.
DNA stands for Deoxyribonucleic acid. It is made up of two complementary strands. There are four nitrogenous base present in the DNA strand. These are-
Adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair with bases on the complemenatry strand just according to the Watson and Crick base pairing ( A=T, G ≡ C ). Uracil is another nitrogenous base. But it is present in RNA in place of Thymine.
Thus, bases found in the DNA are Adenine, thymine, guanine, cytosine.

How might a mat of mosses protect a forest?
Answer:
Mosses play important roles in filtering and storing the water and nutrients that forests need to survive and grow. Mosses are important because they help regulate water in the forest ecosystem by slowly absorbing and releasing rainfall while keeping nutrients in place. Their nutrients and water come from rainfall or running water.

When 10 grams of water completely evaporate into water vapor, the volume of the water vapor is greater than the volume of the original liquid water, but the mass remains the same. Why does the mass stay the same?
Answer:
A very small amount of water vapor enters the atmosphere through sublimation, the process by which water changes from a solid (ice or snow) to a gas, bypassing the liquid phase.
Explanation:
Water vapor is released into the atmosphere by sublimation, which avoids the liquid phase and changes water directly from a solid (ice or snow) to a vapor.
What is the change in physical properties?If you allow water to evaporate inside a sealed container, the container carrying the water and the water vapor will all have the same mass before, during, and after evaporation.
At air pressure, water reaches the same molecular/volume density as air (air is mostly nitrogen). The density of water vapor decreases with its rate of expansion.
The process through which stuff transforms from a liquid to a gas is called evaporation.
When a gas transforms into a liquid, condensation takes place. All matter is composed of tiny, movable units called molecules.
Therefore, no effect on mass due to change in phase
