Answer: Weather, food competition
The variables that would affect the rate of the population whether it is increase or decrease are as follows;
Environmental conditions.Competition with other organisms. Available resources like food and space.What do you mean by Population?A Population may be defined as a group of individuals belonging to the same species living in the same area at a definite given time.
Environmental conditions vary from place to place which directly affects the rate of the population by influencing the relative fitness of organisms. The competition also inhibits the fitness and survivability of organisms.
It may be intraspecific and interspecific. While food and space together lead to resources that are available for the organisms in order to reproduce themselves under natural conditions.
Therefore, the variables that would affect the rate of the population whether it is increase or decrease are well described above.

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.

What is the main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants?.
The main thing that drives water to move up from roots through the stem or trunk and to the leaves in plants is evaporation from the leaf pores
As water molecules evaporate from plant leaves, they attract water molecules that remain in the plant, assisting in the water flow from the roots to the stems. The combined effects of capillary action and transpiration transport water from the roots to the leaves of a plant.
Because water molecules tend to grip together (cohesion) and stick to the walls of tubes, they rise from the roots to the leaves (adhesion). The water evaporating from the leaf surface aids the root system's capacity to absorb additional water. This mechanism is known as capillary action.

Explanation:
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.

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.

Find 2 plankton, one that exhibits bilateral symmetry, be creative.
Hurry up, and it's due today!
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.
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.

What is the evidence that chiasmata are points of physical exchange between chromatids?.
The evidence that chiasmata are points of physical exchange between chromatids is Cytological markers such as knobs and translocations.
The chiasma is a structure that develops through crossover recombination between a pair of homologous chromosomes and physically connects the homologous chromosomes during meiosis.
Cytological markers are those that are connected to variations in chromosome number, shape, size, and banding pattern. To put it another way, it alludes to the chromosomal banding caused by various stains, such as G banding.
Hence, in chiasmata when the crossing over structure is formed then with the help of cytological markers it can be easily observed and thus it can give physical evidence of exchange and thus these crossing over forms can be easily detected with markers.
