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).
Answers
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.

DNA _____.
is a long, single chain of nucleotides
cannot determine behavior traits
contains coded information for the creation of proteins
is enclosed by a nuclear membrane in prokaryotes
Answers
Answer:
Answer:
The correct answer would be "contains coded information for the creation of proteins".
DNA or deoxyribonucleic acid is a polymer of nucleotides.
It is the genetic material in most of the living cells present on earth. That is, it controls all the characters and traits of the living organisms.
In prokaryotes, it keeps floating in the cytoplasm whereas it is confined in the well-defined nucleus in eukaryotic cells.
The nucleotide sequence of the DNA is used as the code for the synthesis of the proteins.
It is first transcribed into the nucleotide sequence of mRNA which is further decoded into the amino acid sequence of the proteins.

If a population pyramid has a very broad base then what does that tell you about the population it represents?
Answers
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.

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.

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.
Answers
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.
What is one of the reasons why Gregor Mendel chose to study pea plants?
They exhibit only a single trait.
O They produce flowers.
They grow very slowly.
They reproduce sexually.
Answers
Answer:
They reproduce sexually
One of the primary reasons why Gregor Mendel chose to study pea plants is because they exhibit only a single trait. This trait can easily be identified and studied, making it easier for Mendel to trace the inheritance patterns of the trait.
What Mendel was able to perform?Mendel was able to cross many pea plant kinds and see the progeny grow. He was able to research these offspring and determine how the trait was passed down through each generation.
Furthermore, Mendel's tests were made simpler by the ease with which pea plants are grown and maintained. Mendel opted to study pea plants because they have sexual reproduction as another reason.
Mendel was able to analyse the inheritance of traits by crossing two separate plants, which is not possible with asexually reproducing plants, as a result.
Mendel was also able to analyse the transmission of traits across numerous generations, which is impossible with asexually reproducing plants. Mendel was able to track the inheritance patterns of a trait correctly as a result.

How might a mat of mosses protect a forest?
Answers
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.
