Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?
Answers
Answer:
3/16
Explanation:
This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).
In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:
9/16 of Round, yellow offsprings (R_Y_)
3/16 of Round, green offsprings (R_yy)
3/16 of Wrinkled, yellow offsprings (rrY_)
1/16 of wrinkled, yellow offsprings (rryy)
Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

which term is used to describe the histologic characterization of tumor cells? group of answer choices staging grading cachexia angiogenesis
Answers
Grading is the term that is used for histologic characterization of tumor cells.
The grading of a tumor cell helps us understand the severity of the tumor. If a cell looks more normal, then this will means that the tumor is not in such a bad condition. However, if the grading shows that the cells are more abnormal, then the condition will be more severe. In this way, grading is used for the histologic characterization of tumor.
To grade a tumor, a doctor will have to perform a biopsy in order to obtains tissues from the specific area of the body. The values for grading a tumor are X, 1, 2, 3, or 4.

Hurry up, and it's due today!
Answers
Answer:
The correct answer is - Diatoms (phytoplankton) and cephalopods like squid (zooplankton).
Explanation:
Bilateral symmetry is the symmetry of the body where one side of the body is the mirror image of the other side of the body. Organisms that are found in the water or can not move without the current of water, called planktons. Planktons can be either animals or plants. The two examples (one from zooplankton and one from phytoplankton) are as follows:
The cephalopods like squid (zooplankton) - The cephalopods are the group of planktons in which most of the organism like squid and others has bilateral symmetry.
Diatoms (phytoplankton) - The most common phytoplankton is diatoms and the pennate diatoms show bilateral symmetry.

Substance A requires cellular energy to transfer into a cell. While examining a body after death, a forensic scientist finds substance A in the victim's cells. What can the scientist reasonably conclude?
Active transport moved substance A into the cells after death.
Decomposition moved the substance into the cells.
Passive transport moved substance A into the cells.
Substance A moved into the cells before death.
Answers
The correct answer is the last option which states that Substance A moved into the cells before death.
This is because, Substance A requires cellular energy in order to transfer into a cell. This occurs through a process called active transport. Active transport in cellular biology refers to the movement of molecules or ions across a cell membrane against the concentration gradient from a location of lower concentration to a region of higher concentration. Cellular energy is needed for active transport in order to achieve this movement. After death, the chemical reactions that produce energy in the body stop. Hence, this process can only take place when a person is living.The forensic scientist found the same substance A and not it's decomposed constituents in the cell. Moreover, passive transport cannot take place since Substance A requires energy for transport. So, the other options are incorrect.Hence, the scientist can reasonably conclude that Substance A moved into the cells before death.

Why does a pea plant with the genotype Rr produce some gametes that have the allele for round seeds?
Answers
Answer:
The correct answer is - due to the law of segregation.
Explanation:
In the given case the genotype of Rr and as we know R is a dominant characteristic for round seeds and r represents the recessive allele for wrinkled seeds in a pea plant. So if a plant has Rr in its genotype it means it is a phenotypically round pea plant due to dominance in this heterozygous case.
The law of segregation states that two alleles of a gene of a specific trait will be distributed randomly and there is an equal chance of each allele to end up in the gametes, similarly in this case both alleles can be segregated to gametes and it is a random process.

A male shark has 40 chromosomes in each of its sex cells. How many would be present in its body cells?
Answers
Answer:
80 sex cells would be present in its body cell
If a male shark has 40 chromosomes in each of its sex cells, then the number of chromosomes that would be present in its body cells is 80.
What are Chromosomes?Chromosomes may be defined as thin, thread-like structures that appear during the process of cell division. Chromosomes are typically found in the nucleus in the form of chromatin thread and these threads are made up of DNA, RNA, histones, etc. Chromosomes were first discovered by E. Strasburger in 1875.
It is a significant feature of the germ cells or sex cells that they usually contain half the chromosomes in their cells as compared to the normal body cells. These types of cells undergo meiosis.
The half number of chromosomes from each parental cell is successfully fused in order to produce an organism that has normal chromosomes.
Therefore, there are 80 chromosomes that are present in the body cells of a male shark if it has 40 chromosomes in each of its sex cells.

A prokaryote that obtains both energy and carbon as it decomposes dead organisms are Heterotroph and Chemotroph.
Heterotrophs are those organisms that feed on other animals and plants and obtain their energy from them. Examples include mammals, snakes, insects, tigers, lions, etc.
Chemotrophs are those organisms that decompose other organisms and obtain their energy by oxidizing the inorganic molecules.
The most common type of organisms that falls into this category is prokaryotes. It includes organisms such as bacteria, fungi, etc.
These organisms release specific enzymes to decompose the dead organism matter and alter its physical state.

Two different environmental factors that might affect the amount of meat or milk that cattle produce may include the temperature and also water availability, since both factors may negatively (or positively) affect the amount of meat or milk in cattle animals.
What are environmental factors?The expression of environmental factors refers to all external factors instead of genetic factors that influence the development of phenotypic characteristics of individuals and populations in an ecosystem.
The major environmental factors that alter the development of an individual may be both biotic (e.g., food availability) and abiotic conditions (e.g., light, temperature, water H2O availability, etc) because both influence organism features.

Water is important to plant cells because it is used as one of the reactants in the process of photosynthesis. What is another reason why water is important to plant cells?
Answers
Answer:
Water helps to maintain turgidity in plant cells.
Turgidity can be defined as the amount of water that is required to make water to exert internal force from inside the plant cell. This is called as turgor pressure it exerts the pressure on the plasma membrane against the cell wall. This process maintains the rigidity inside the plant cell and cells exert external turgor pressure on the neighboring cells that creates a tension, which allows plants to stand erect. Without the amount of appropriate water, the plant cells will collapse and plants will be wilted.
Therefore, water helps to maintain turgidity in plant cells is an important property of plant cells.
