Which statement is a hypothesis that would best address the question, "Are black-tailed prairie dogs dying to sylvatic plague and causing the population to decline?"
A hypothesis is a claim the researcher makes to stablish a relationship between variables and predict the results of the experiment or explain what thinks is going on. Note: Since I did not find the options, I provide examples below.
What is a hypothesis?
When following the scientific methodology, researchers must formulate a hypothesis.
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, not a fact. It is a claim of how it works a relationship between two or more variables.
The researcher hypothesizes to predict what is going on or what is expected to occur.
A hypothesis
• must be clear and comprehensive.
• must express the direct relationship between the involved variables.
• must be objective.
• must be testeable and falsifiable
There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative
Question: "Are black-tailed prairie dogs dying to sylvatic plague and causing the population to decline?"
The variables involved in this question are,
Independent variable: sylvatic plague presenceDependent variable: black-tailed prairie dogs survival or death.population size change
Note: Since I did not find the complete question, I will propose a few potential Hypothesis as examples for you to understand the structure.
Hypothesis:
If black-tailed prairie dogs are exposed to sylvatic plague, then their mortality rate will increase, declining their population size.
If black-tailed prairie dogs are exposed to sylvatic plague, then their survival rate will decrease, declining their population size.
If black-tailed prairie dogs are exposed to sylvatic plague, then their population size will decline.
Another alternative is to think that variables are,
Independent variable: black-tailed prairie dogs dying to sylvatic plague or to other causesDependent variable: Population size changeHypothesis:

The outer cell wall in bacteria that consist of a cell wall is called protoplasm.
What is a bacterial cell wall?For the majority of bacteria, the maintenance of cell shape and structural integrity depends on the intricate, mesh-like structure of the bacterial cell wall. Due to its importance for most bacteria and absence in eukaryotes, the cell wall has historically attracted a great lot of study attention.
This makes it a prime candidate for some of our most potent antibiotics. Bacterial cell wall fragments may also have immunostimulatory and cytotoxic capabilities, which makes them significant players in disease pathogenesis. The majority of the cell wall is made up of peptidoglycan (PG), a network of polysaccharide strands that are cross-linked by short peptide bridges coupled to the MurNAc residues and have a poly-[N-acetylglucosamine (GlcNAc)-N-acetylmuramic acid (MurNAc)] backbone.

In the origin of cells, why was it important that complex molecules become enclosed in a lipid membrane?
In the origin of cells, it was important that complex molecules become enclosed in a lipid membrane so that the complex molecules could be isolated from the environment and also to stop them from diffusing.
A cell membrane is a semi-permeable membrane made of lipids and other compounds. The lipid membrane separates the interior of a cell from the exterior of the cell.
In the origin of cells, the presence of a cell membrane was important in order to form life. Without the cell membrane, all the complex molecules required for existence would not have been separated from the outside environment. Also, many of the molecules would have diffuses if a lipid membrane was not present around them.
