Does the protein solution have a high molarity? what is evidence for your conclusion?

1 answer:

8 0

NO, the protein solution do not have a high morality. The protein solutions generally have lower molarities. This is because protein molecules are larger in size and do not form a soluble and uniform solution. Protein molecules do not dissolve in solutions.

Name two types of evidence used to support the theory of evolution. Explain how scientists use each type of evidence to provide

TEA [102]

Evidence for evolution, in other words evidence of common descent, include fossils, which have shown a (fairly) steady change in morphology over time for some species. An example would be horse hooves: we have fossils that show when they were still three toed, then two toed, then one toe in our present day horses. Another piece of evidence is vestigial organs. An example of vestigial organs is wings in some flightless birds, such as the kiwi. Their ancestors used it in order to fly across the marine barrier into New Zealand, but natural selection and random genetic drift made them quickly lose the ability to fly. Nonetheless, they still have their wings, however small. It can be assumed that eventually, their wings would be reduced to small stubs fused to other nearby bones, as has been observed in their cousins.

Explain how population sizes in nature are regulated

Answer:

Understanding Populations

Section 1 How Populations Change in Size

Objectives

Describe the three main properties of a population.

Describe exponential population growth.

Describe how the reproductive behavior of individuals can affect the growth rate of their population.

Explain how population sizes in nature are regulated.

What Is a Population?

A population is a group of organisms of the same species that live in a specific geographical area and interbreed. A population is a reproductive group because organisms usually breed with members of their own population.

Properties of Populations

Density is the number of individuals of the same species that live in a given unit of area. Dispersion is the pattern of distribution of organisms in a population. A population’s dispersion may be even, clumped, or random. Size, density, dispersion, and other properties can be used to describe populations and to predict changes within them.

How Does a Population Grow?

A population gains individuals with each new offspring or birth and loses them with each death. The resulting population change over time can be represented by the equation below.

Growth rate is an expression of the increase in the size of an organism or population over a given period of time. It is the birth rate minus the death rate. Overtime, the growth rates of populations change because birth rates and death rates increase or decrease. For this reason, growth rates can be positive, negative, or zero.

For the growth rate to be zero, the average number of births must equal the average number of deaths. If the adults in a population are not replaced by new births, the growth rate will be negative and the population will shrink.Explanation:

Which statement describes competition in an environment? Organisms share a place to sleep. A living thing consumes berries on a

Over [174]

Answer:

Sunlight shines only three months out of the year.

Explanation:

I think this is right

Because abundance means a large amount so there would be no competition there.

If organisms share a place to sleep then that means no competition

If a living thing is consuming berries on a tree then the living thing is just eating

But if the sunlight only shines three months out of the year then that can cause a shortage of food in the environment causing for the living creatures in the environment to compete for the food that is left since there won't be enough to supply for and abundance of living things.
