What is a habitable zone? O A. It's a zone where planets slow down their speed of rotation to capture more sunlight. O B. It's a zone in which all planets have oxygen in their atmospheres. OC. It's a zone that is the right distance from a star for liquid water to be possible. O D. It's a zone where the harmful UV rays of a star cannot reach a planet's atmosphere.
Answer: C. It's a zone that is the right distance from a star for liquid water to be possible.
Explanation:
The definition of “habitable zone” means the distance from a star at which liquid water exists. Habitable zones are known to be neither too hot nor too cold for life. An example is: If Earth were at the same distance Pluto is, then liquid water wouldn't exist, because it would freeze, and become ice. Now, if Earth was at the same distance Venus is, then liquid water wouldn't exist, because it would become too hot and dry, which means that any organism won't be able to survive in those circumstances.

Answer:
Controls allow the experimenter to minimize the effects of factors other than the one being tested. It's how we know an experiment is testing the thing it claims to be testing. This goes beyond science — controls are necessary for any sort of experimental testing, no matter the subject area.
Explanation:
Hope it helped <3
The role of control in an experiment is to minimize the effects of factors.
Scientific control is an experiment in which a subject (or a group of subjects) is not tested for a dependent variable (or variables). The addition of control to an experiment is essential for obtaining the results of the empirical data.
A control variable is a variable that is held constant throughout a study. It is not a study variable, but it is controlled because it has the potential to affect the study results.
It is used for comparisons to confirm the results of an experiment. It is used to guarantee that the measured dependent variable is influenced only by the changed independent variable and not any other variables (controls) in the experiment.

A. lipids are created by the synthesis of glycerol.
B. amino acids are linked to create a polypeptide.
C. nucleotides are formed by translation.
D. complex carbohydrates are converted into monomers.
Answer:
B
Explanation:
The ribosome reads the codons in the RNA sequence and coded amino acids. These amino acids join with a peptide bond and form a polypeptide (protein). This protein can be used for many functions in the body.

Complete the sentence. The ________________ of extra rabbits into a forest ecosystem can affect the population of other herbivores already living there.
- birth rate
- death rate
- emigration
- immigration
The immigration of extra rabbits into a forest ecosystem can affect the population of herbivores living in the forest.
What is immigration?Immigration is the movement of people or animals from external locations into a population.
With new individuals moving into a population, the population size increases with other factors being constant.
With the increase in the population size, competition for resources increases accordingly.
Thus if extra rabbits move into a forest ecosystem, the population of herbivores existing in the ecosystem would be affected because competition for food would increase.
