Answer and Explanation:

The people within this age range most likely want a baby for themselves/want more babies, or they don't feel like they should have to be limited to the amount of babies they want. Since it is their life and their bodies, they think it is up to them to decide how many to have and whether to have one or not.

The best wave represents ultraviolet rays is Wave B.

Ultraviolet (UV) radiation is a type of non-ionizing radiation that is emitted by the sun and unnatural sources, such as tanning .

Exposure to UV rays can cause early ageing of the skin and signs of sun harm such as creases , leathery skin, liver bumps, actinic keratosis, and solar elastosis.

UV beams can also generate eye pains. They can force the cornea to become inflamed or ignited.\

Thus, the option "B" is correct,  Ultraviolet (UV) radiation is a type of non-ionizing radiation that is emitted by the sun and unnatural sources, such as tanning .

Answer: biologists are a type of scientist that use dichotomous.

The Type of scientists that uses dichotomous key is : Biologist

A lot of scientists make use of the Dichotomous key for identifying unknown biological organisms like Biologists. A dichotomous key consists of a set of choices, with each choice consisting of two statements, these statements makes it possible to name an unknown biological organism.

A dichotomous key is a simply method used for the identification of organisms ( groups of unknown organisms are repeatedly divided into two groups to get more information about the organism )

Explanation:

An excessive amount of greenhouse gases cause the earth's temperature to rise and contribute to climate change. I didn’t do the simulation but too many greenhouse gases are bad for the environment. They raise the temperature of the earth instead of maintaining it.

Organic Process: a natural process occurring in living organisms

Answer:

Change in food source.

Explanation:

If there is a change in food source, then the organism will have to adapt to that change. For example, with Darwin's Theory on the finches on the Galapagos Islands. There were many different varieties from different size to different beaks. This was because of changes on food sources and they adapted to obtain them more.

Natural selection can contribute to variations in gene frequency throughout time as a result of changes in food supply.

If the organism's food supply changes, it will have to adjust to the new situation.

For example, Darwin's Theory on the Galapagos Islands' finches. There were several distinct types, ranging in size and beak shape. This happened due to changes in food supplies, and they evolved in order to access more of them.

Explanation:

There are several key reasons for high biodervisity in tropical ecosystems. High NPP directly contributes to a diversity by supporting more species with minimum viable populations of each organism increase overall mutation frequency and hence intraspecific genetic varation.

Answer:

False.

Explanation:

A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent. During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.

The molecules are still there.

Answer:

The enzyme's activity will be altered

Explanation:

Genes are unit of hereditary that carries genetic information needed for the survival of the cell and organism at large. Genes are expressed via transcription and translation processes to produce a protein, which is responsible for the physical traits we can see (phenotype).

Since ENZYMES that catalyze biochemical reactions in living cells are proteinous in nature i.e. are made up of proteins, this means that they are formed from the expression of genes. Hence, if the gene encoding the production of an enzyme is altered or changed due to mutation, then the activity of the resulting enzyme will also be altered (most times non-functional).

Answer:

Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

This method  of natural selectionthat the fantastic alleles of this variation organism are surpassed directly to offspring, the system of  natural selection results in evolution occurring.

Natural selection is the system thru which populations of residing organisms adapt and extrade. Individuals in a populace are evidently variable, which means that they're all one of a kind in a few ways.

Explanation:

They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere.

The Miller-Urey experiment tested the hypothesis that life, or more precisely organic molecules, might have arisen by nothing more than straightforward chemical processes by simulating the conditions on the early Earth.

Miller's result confirmed A.I. Oparin's theoretical hypotheses, and it is regarded as the standard experiment looking into the hypothesis of abiogenesis.

The Miller-Urey experiment was the first attempt to investigate theories regarding the beginning of life experimentally. Stanley Miller recreated circumstances that were supposedly typical on the early Earth.

Therefore, They showed that organic molecules could be formed from materials nypothesized to be available in the Earth's early atmosphere.

Answer:

Movement occurs from higher concentration to lower concentration.

Explanation:

Strip A cell has 30% of sugar which is placed in a solution of 10% sugar so the sugar that is present in the potato strip A moves from inside to the outside due to the process of osmosis while on the other hand, if strip B was placed in 50% of sugar solution so the sugar moves inside from outside environment through semi-permeable membrane. This movement occurs due to difference in concentration of both environments i.e. cell and solution.

Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50%  sugar concentration

a) strip become flaccid and strip B will swell

b) hypotonic solution causes movement of water to diffuse out of cell

Salts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution

Thus, Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50%  sugar concentration

a) strip become flaccid and strip B will swell

b) hypotonic solution causes movement of water to diffuse out of cell

The fish would grow in the population, because osprey mainly eat fish.

Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.

Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.

Answer:

through years of evolution as natural selection shaped animal adaptations to Earth's environments.

Explanation:

Over the years, biologists have been able to successfully name more than one (1) million animal species across the world. These species arose through years of evolution as natural selection shaped animal adaptations to Earth's environments.

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
