The expected phenotypic ratio for a cross between two individuals that are heterozygous for a given trait is 3:1.
<h3>What is Phenotype?</h3>
This is referred to the physical characteristics of an organism such as the size, shape etc.
When two heterozygous traits are crossed:
Rr × Rr ⇒ RR Rr Rr rr
The ratio is therefore 3:1 of the dominant to recessive phenotype.

Answer:
D. Cell wall
Explanation:
Cell wall is also present in prokaryotes it is made of peptidoglycan layer.
Answer: they would have diarrhea, stomach cramps, vomiting, and a fever.
Explanation:
- The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
- The schematic representation in the diagram helps in the understanding of the setup for the experiments.
- The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
- A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.
<h3>What are the four foremost factors of a managed test?</h3>
When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
- In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.
The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
- The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.
- The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.
- The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.
- The flow chart for the increase in pressure affecting the evaporation is given in the image attached.

All the different plant populations make up the plant community in this swamp. The plants are part of a bigger ecosystem that contains many abiotic and biotic factors.
<h3>What is an Ecosystem?</h3>
An ecosystem may be defined as a place or an area that involves individuals of different species that live together and interact with one another for the purpose of food, shelter, and space.
In ecology, a community may be defined as a group of individuals belonging to different species that are living in the same area at a given time.
So, all the different plant populations make up a plant community.
Therefore, the community is the collection of all different forms of species but the ecosystem is the community has highly influenced by abiotic and biotic factors.
