As a predator population increases, the population of its prey will often
A decrease.
B increase.
C remain the same
Scientists have been studying four populations in a swamp area. In this area, alligators eat gar (a type of large fish), and both gar and diving ducks eat crabs. The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.
Answer:
There wouldn't be enough resources for the alligator population to live off of thus decreasing its population number. This decrease affects the other populations because it without alligators, its predators and prey wouldn't gain its nutrition from it and it would overall change its environments' habitation. The gar population would increase because they wouldn't be eaten by the alligators and therefore increasing the diving duck population as well. The crab population would decrease because the gar (their prey) population increased which overcomes the number of crab in the population.

Which mutation scenario will always lead to natural selection?(1 point) A. a mutation causes a specific advantage within the population B. a mutation causes an inactivated gene to be reactivated C. a mutation causes a specific variation within the population D. a mutation causes a gene to become inactivated
A mutation scenario that will lead to natural selection is one that causes a specific variation within the population. Thus, the correct option for this question is C.
What is Mutation?A mutation may be defined as a type of process that significantly involves sudden, stable, and inheritable changes in the genetic material of an organism. The organism that undergoes mutation is called a mutant. The agent of mutation is called mutagen.
According to the context of this question, the process of mutation never causes a positive influence on the organisms, but with respect to time organisms become adapted or habitual.
A Mutation may be random and spontaneous so, it does not always involve an inactivated gene being reactivated. It sometimes involves the introduction of a new gene that facilitates specific functions.
Therefore, a mutation causes a specific variation within the population is a mutation scenario that will lead to natural selection. Thus, the correct option for this question is C.

What type of chemical bond exists between two water molecules
Hydrogen bonds, type of chemical bond exists between two water molecules.
What is a chemical bond?A chemical bond is what binds atoms in molecules together. Electrical forces between positive charge atomic nuclei and negative-charged electrons form bonds. A chemical bond is a long-lasting attraction between ions or atoms that allows molecules and crystals to form.
Hydrogen bonds arise between neighboring water molecules' hydrogen and oxygen atoms. A hydrogen bond is formed by the attraction of individual water molecules. A water molecule is made up of two hydrogen and oxygen atoms atom, with one partly positive hydrogen atom connected to a more highly electronegative atom.

Answer:
directional selection
Explanation:
Directional selection is a type of natural selection where individuals exhibiting an extreme phenotype for a given trait are favored over the mean or other extreme phenotype. This type of selection can lead to drastic and fast changes in allele frequencies between generations in a population, being particularly important in speciation processes. Directional selection is common under environmental changing conditions (e.g., weather, climate, food availability, etc) or when individuals migrate to other regions in order to adapt to new environmental pressures.
