Explanation:
Wild diploid wheat has seven chromosomes in its pollen. Discuss the major events that had to occur for tetraploid pasta wheat to have evolved. Describe the genome and fertility of pasta wheat (number and kinds of chromosomes).
Answer:
Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization
Explanation:
Durum wheat (Triticum durum) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: Triticum monococcum (genome AA) and one wild progenitor (genome BB). Triticum durum is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.

How does heat affect enzymes?
Answer:
Temperature
Explanation:
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Extreme pH values can cause enzymes to denature.

C) determine the nucleotide sequence for the improved enzyme.
D) synthesize the gene for the improved enzyme.
E) use siRNA to produce the enzyme.
Answer:
C) determine the nucleotide sequence for the improved enzyme.
Explanation:
Computational enzyme design (CED) can be defined as a bioinformatic in silico approach used to model, construct, and enhance enzyme catalysis. CED uses complex optimization algorithms that enable to direct evolution by using computational systems. As a further step, after the modelization of optimal enzymatic activity, bioinformaticians require to determine the nucleotide sequences which will be subsequently used to synthesize the corresponding enzymes.

What is DNA?Deoxyribonucleic acid is a polymer made up of two polynucleotide chains that coil around each other to form a double helix that contains genetic instructions for the development, functioning, growth, and reproduction of all known organisms and viruses. Nucleic acids include DNA and ribonucleic acid.
The fraction of the DNA double helix that supplies structural support to the molecule is known as the phosphate backbone.
The DNA molecule is made up of two strands that wind around each other like a twisted ladder. Each strand has an alternating backbone of sugar (deoxyribose) and phosphate groups.
A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) linked to a phosphate group and a nitrogen-containing base.
Thus, the correct option is B.

Compare the normal allele for hemoglobin with the sickle cell allele. How does this difference affect the person’s red blood cells?
Answer:
Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.

Why is the Earth, moon, and all of the other planets layered?
Planetary scientists are pretty sure that Mercury, Venus and Mars also have these layers. ... Not just planets have a core, mantle and crust. Several moons in our solar system have them! The Moon has a core and mantle similar to Earths but the crust is basaltic rock.
Hope it helps you
Answer:
Planets have different layers because different materials have different densities.
Explanation:
Density comes into play on how heavy matter is at a certain size. The planets formed as dust, gas, asteroids and comets collided together.Around the metal cores, the planets have a mantle and crust made of rock

The cell cycle is highly regulated and involves many steps to ensure that a cell is ready to divide. For this reason, cells cycle between interphase and mitosis. Suppose a cell culture of 1,000 cells is grown, in which the cells cycle every 24 hours. For a single cell, it takes about two hours from the formation of the dissolution of the nuclear envelope to the separation of two daughter cells.
Which of the following best describes the approximate number of cells in the culture that are in interphase, as well as the consequence of the severe disruption of interphase in mitotic division of cells within a tissue?
A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.
B) There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.
C) There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.
D) There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.
Answer:
The two major phases of the cell cycle include mitosis (cell division), and interphase, when the cell grows and performs all of its normal functions. Interphase is further subdivided into G1, S, and G2 phases. After the synthesis phase, the cell proceeds through the G2 phase.

Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt. Which statement is correct? 12/16 white: 3/16 green: 1/16 yellowA) At least one copy of both dominant alleles results in white; at least one copy of one of the dominant alleles also results in white, but at least one copy of the other dominant allele produces green; and the absence of either dominant allele produces yellow.B) If both dominant alleles are present, the result is green. At least one copy of one specific dominant allele is required for yellow. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.C) At least one copy of each dominant allele results in white, at least one copy of either dominant allele produces green, and the absence of either dominant allele produces yellow.

I need some to calculate this for me.
Pro Tip 1: To calculate the % of cells at rest (in interphase), divide the number of cells in interphase by the total # of cells in the slide (cells in telophase may look like they are almost 2 cells, but you can still count them as 1).
# of cells in interphase ÷ total cells = % of cells at rest
Pro Tip 2: To calculate the % of cells dividing (or mitotic index), add up the cells in prophase, metaphase, anaphase and telophase. Divide that number by the total # of cells in the slide.
# of cells in PMAT ÷ total cells = % of cells dividing (or mitotic index)
Answer:
INTERPHASE PROPHASE METAPHASE ANAPHASE TELOPHASE % of Cells at Rest (interphase)
% of Cells Dividing (Mitotic Index)

Normal Ovary 9 cells 5 cells 3 cells 1 cell 2 cells 45% 55%
Cancerous Ovary 3 cells 6 cells 5 cells 3 cells 3 cells 15% 85%
Explanation:
The answers are also down below in the chart if that helps you better make sense of them.
There are 20 cells in each column, to find the ones at rest we simply take the first number in the column and devide it by the number of cells (in this case 20) once we find the percent of cells at rest, we subtract from 100 to see the cells deviding!
