"Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next."
Through his work, Mendel published his experiments to explain his findings.

What did his laws of inheritance state?
SELECT ALL THAT APPLY
A.Parental genes are randomly separated from the sex cells so that sex cells contain only one gene of the pair.

B.Each trait of an organism can contain multiple alleles of that trait.

C.Organisms with alternate forms of a gene will express the dominant form of the gene.

D.The inheritance of one trait is not dependent on the inheritance of another.

E.Genes can be transferred from the parent generation directly to the offspring based on the environmental factors surrounding the offspring.

Do you think these fish are an example of natural selection among two populations of the same species? Explain your answer.​

Answers

Answer:

It depends on the fish (I do not see any pictures) Any fish is an example of natural selection.

Explanation:

A good example would be that polar bears grew and evolved to have white fur to blend in the snow to sneak upon prey. However, their brown bear counterparts failed to do that. So due to better camouflage and hunting technique, the polar bears survived more up north.

Answer:

The two fish are of the same species because they can mate with each other. Also, the characteristics of the blind cave fish enable them to live in caves. Eyes need energy. So, developing bodies with no eyes allowed these fish to function more efficiently.

b) Identify a dependent variable in the experiments. Identify the reasoning of the scientists when they tested the number of colonies produced by strains C3-PBB and C6-PBB . The scientists also analyzed the number of colonies produced from each of the environmental and clinical isolate strains when the strains were plated on a growth medium lacking the toxic chemical. Justify this analysis.

Answers

A dependent variable is the number of colonies produced. The experiment gives a useful insight into the toxicity of the chemicals.

A scientific experiment must always have a dependent and an independent variable. A dependent variable is the variable whose outcome is being determined by manipulating the independent variable which in this case is the presence or absence of the chemicals.

Toxicity of chemical substances is a very important information to scientists as such this experiment is very important because it highlights the toxicity of the chemicals to living things.

which part of the amino acid most likely contributes to the hydrophobic behavior if this region in the polypeptide

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete, however, the side chain is usually the part of an amino acid that is either hydrophilic or hydrophobic in nature. When the side chain has little or no polarity (i.e they lack the ability to interact with highly polar water molecules), the amino acid exhibits hydrophobic properties. Hydrophobic (water-fearing) substances are substances that do not interact/dissolve in water.

What is one advantage of urbanization?

Answers

Answer:

Advantages of Urbanization

Urban residents in many parts of the world tend to live longer than do rural residents, and have lower infant mortality and fertility rates. Cities provide better access to medical care, family planning, education, and social services. Recycling is more economically feasible.

Ventajas de la urbanización:

Crecimiento sostenido. El crecimiento de las ciudades va acompañado de una mayor demanda de servicios básicos y de bienes de consumo, lo cual genera un mercado mayor a satisfacer.

Concentración poblacional. Las ciudades son ámbitos más controlables por los Estados y con mayor facilidad de cobertura de redes de servicio o de distribución, dado que la población se concentra en algunos kilómetros a la redonda.

Complejización laboral. El mercado de empleo en la ciudad es mucho más diverso y variado que en las zonas rurales, permitiendo así el desarrollo y complejización de las actividades industriales, comerciales y de servicios.

Make a list of ecological consequences that you can infer have occurred on Guam due to the introduction of the invasive (nonnative) brown tree snake

Answers

Answer:

There are many ecological consequences that could have, or already have, occurred.

Invasive species are notorious for the chaos and destruction they bring upon ecosystems. As an ecosystem is perfectly balanced, a new factor causes this to become askew. The brown tree snake may hunt prey that is the main diet of a different species there. This may cause both the prey and native species to begin to die off, and if the prey goes extinct because of this, the native species will as well, unless they somehow adapt. Not only this, the brown tree snake is known for causing frequent power outages by climbing on electrical wires. They are the cause of the loss of 9 out of 11 forest birds native to Coco's island. They are causing a serious decline in birds, rodents, lizards, and even bats in Guam.

All of the dinosaur periods are at the start of Earth's timeline, and "the end of life's start" suggests the end of dinosaurs, meaning, when the asteroid hit. So it's probably one of the Mesozoic periods.

The T-rex first appeared in the Cretaceous Period, and the asteroid hit somewhat during middle of the Cretaceous Period.
