Why does a pea plant with the genotype Rr produce some gametes that have the allele for round seeds?
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 prokaryote that obtains both energy and carbon as it decomposes dead organisms.
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.
They obtain carbon and energy from matter to survive.

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?
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.

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.
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.

Suggest two environmental factors which can affect the amount of meat or milk cattle produce. Give an explanation as to how/why these factors affect the production.
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.
In conclusion, 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.

Looking at a microscope slide under the microscope, you see an E. coli cell, a cork cell, and a mouse cell. Which cell is most likely going to be the smallest?
E. coli
Mouse cell
Elephant cell
Cork cell
Answer:
cork cell I think.... ..
out of the cells of an E. coli cell, a cork cell, and a mouse cell. The E. coli cell is most likely going to be smaller than the mouse and cork cells because these two are eukaryotic cells with lots of organelles. First one is true.
What are the different types of cells?Cells are different types, such as prokaryotic cells, eukaryotic cells, etc., and they are divided on the basis of the nuclear membrane. The prokaryotic cell is comparatively smaller than the eukaryotic cell as these eukaryotic cells have many organelles in them such as the nucleus, mitochondria, etc.
The plant cell is larger than the animal cell because it has an extra cell wall surrounding it, an extra chloroplast, and a large vacuole, all of which eukaryotes lack. Here, the cork cell is a plant cell, so it is the biggest out of all, while the mouse cell is an animal cell, so it comes in second, and the E. coli is the bacterial cell, and it comes in last in terms of cell size.
Hence, the smallest cell is E. coli.

which term is used to describe the histologic characterization of tumor cells? group of answer choices staging grading cachexia angiogenesis
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.
