Answer:

Federal treaties

Explanation:

Native Indian Americans have been dependent on hunting and fishing way before the land was colonized by settlers. They depend on these practices not only for food but also for trade, medicines etc. When they decided to give up their land to the federal government, various treaties were signed between them and the government. These treaties continued to give them the rights to fishing and hunting even on reserved water bodies and land. Many of the fishing regulations that apply to the rest of the Americans are not applied to the natives and they enjoy exclusive fishing rights in many places.

1) Natural Selection- General speaking, something must cause differential reproduction and then better suited individuals will survive over time.

- Detailed Explanation -

Natural selection is the process in which individuals whom are better suited to their environment will have an increase in fitness. It occurs over multiple generations and can take a very long period of time to occur.

For natural selection to occur, the following must be true:

1. There must be variation in traits (every individual can't be identical)

2. There must be differential reproduction (some individuals are more likely to reproduce than others)

3. Traits are passed on from generation to generation

Thus, the first step in natural selection is that something must cause differential reproduction. This could be the introduction of a predator, a disease, a random mutation that is detrimental, a change in resource availability such as a drought, and so forth.

This image shows how a genetic mutation is unfavorable and is selected against, but the same process holds for a gene that is unfavorable during any scenario.

This event causes some individuals to survive and reproduce and some to be less successful. For example, a predator is introduced and it hunts and kills mostly individuals with shorter legs that run slowly. Or the environment undergoes a long drought and individuals in the species who have a gene that helps them perspire (sweat) less are more successful.

Over multiple generations, the genetic composition of the species changes. Maybe within six generations the predator has completely wiped out individuals with shorter legs. Maybe within two generations the drought completely eliminates individuals with a gene that results in excess perspiration. The amount of time will vary.

2) Mutation - A change in the genetic structure of an organism.

Explanation:

Usually, a mutation has to be expressed as some macro-functional characteristic although some may be hidden in internal systems.

3) Genetic Drift- Genetic drift is the change in the frequency of an existing allele in a population due to random sampling of organisms.

Explanation:

The effect of genetic drift is larger when there are few copies of an allele, whereas when there are many copies the effect is smaller.

Genetic drift describes random fluctuations in the number of gene variants in a population. Once it begins, genetic drift will continue until the involved allele is either lost by a population or until it is the only allele present in a population at a particular locus. Both possibilities reduce the genetic diversity of a population.

Genetic drift can cause a new population to be genetically distinct from its original population, which has led to the hypothesis that it plays a role in the evolution of new species.

4) Gene Flow- Gene flow is a concept in population genetics to refer to the movement of genes or alleles between interbreeding populations of a particular species.

Explanation:

Gene flow is an important mechanism for transferring genetic diversity among populations. Migrants into and out of a population may result in a change in allele frequencies, thus changing the distribution of genetic diversity within the populations. High rates of gene flow can reduce the genetic differentiation between the two groups, increasing homogeneity.

It is thought that gene flow constrains speciation by combining the gene pools of the groups and thus, prevents the development of differences in genetic variations that would have led to full speciation. It is expected to be lower in species that have low dispersal or mobility, occur in fragmented habitats, there is a long distance between populations, and smaller population sizes.

It includes different kinds of events, such as pollen being blown to a new destination or people moving to new cities or countries. However, there are certain factors that serve as barriers to gene flow. Some of the factors affecting the rate of gene flow include physical barriers, geological events and geographical barriers.

5)Non Random mating- The nonrandom mating is a selective pattern.

Explanation:

The nonrandom pattern of mating is an assortative pattern of sexual reproduction. During the reproduction, similar phenotypes are selected for mating. It is a random process. It is also known as positive assortative mating.

which region of the cns integrates the reflexes for micturition, defecation, erection and ejaculation?

Oksanka [162]

The cns's spinal cord combines the urination, feces, erection, and ejaculatory reflexes.

<h3>How would you define micturition?</h3>

During the micturition process, the body excretes urine. To evacuate toxins from the body, most people and dogs get an organ system designated as the urea cycle. Micturition is the process to remove urine from the body, to put it another way.

<h3>Are micturition and urinating the same thing?</h3>

The act of removing urine from the urinary bladder, which serves as a storage organ, is known as micturition or urination. The bladder wall's flexible or involuntary muscle is known as the detrusor. The externally and internally sphincters make up the urethral muscles.

A molecule is involved in a chemical reaction, causing the arrangement of its atoms to change. What is the result of this proces

AlladinOne [14]

Chemical reactions occur when different atoms and molecules combine together and spit apart. For example, if Carbon (C) is burnt in Oxygen (O2) to form Carbon Dioxide, a Chemical Reaction occurs.So, during chemical reactions, new product atoms are not created, and old reactant atoms are not destroyed. Atoms are rearranged as bonds are broken and formed. In all chemical reactions, mass is always conserved...In chemical reactions, atoms rearrange to form products. Hope I helped!

How do keystone species shape communities?

laila [671]

Explanation:

A keystone species is an organism that helps define an entire ecosystem. By keeping populations of mussels and barnacles in check, this sea star helps ensure healthy populations of seaweeds and the communities that feed on them—sea urchins, sea snails, limpets, and bivalves.
