Answers

Answer 1

Answer:

Carrying capacity

Explanation:

Section X represents the maximum population size that the environment can support.

Answer 2

Changes in a population of elk are shown in the graph given. The best representation by the letter X is the carrying capacity of the population. Thus, the correct option is D.

What is Carrying capacity?

The carrying capacity of an environment is the maximum population size of a biological species which can be sustained by that specific surrounding environment, it is given the food, habitat, water, and other resources that are available.

Carrying capacity can be defined as the environment's maximal load, which in population ecology corresponds to the particular population equilibrium of that area, when the number of deaths in a population equals the number of births as well as the immigration and emigration of individuals.

The effect of carrying capacity on the population dynamics is modelled through a logistic function. Carrying capacity is applied to the maximum population which an environment can support in the ecology, agriculture and fisheries.

Therefore, the correct option is D.

ANSWER ASAP!! Which type of selection occurs when a population experiences a shift in diversity toward the larger organisms?
1. stabilizing selection
2. directional selection
3. disruptive selection
4. adaptive selection

Answers

Answer:

2

Explanation:

edge 2021

The type of selection that occurs when a population experiences a shift in diversity toward the larger organisms is a directional selection.

What is a selection?It is a phenomenon by which some organisms have better advantage at surviving than the others of the same species.These organisms prevail and are reproductively more successful than the others.What is a directional selection?It is the type of selection in which an extreme phenotype is selected and the rest are at a disadvantage."The allele frequency is shifted in the direction of that phenotype.What is a disruptive selection?

It is the type of selection in which both the extreme phenotypes are favored than the others.

What is a stabilizing selection?It is the opposite of directional selection.In this the mean phenotype is selected and the extreme phenotypes are not.

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

Answers

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.

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.

Answers

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.

What do you mean by food web?

A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community. Another name for food web is consumer-resource system.

Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.

A food web consists of many food chains. A food chain only follows just one path as animals find food. Example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass.

Answers

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.

What type of chemical bond exists between two water molecules

Answers

Answer: Hydrogen bonds

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.
