Answer to question 1?

Answer:

D

Explanation:

A is incorrect because genetic material is not present in the plasma membrane.

B is incorrect because Strand A contains Thymine, meaning it is a DNA strand. RNA is the only genetic material that can be found in ribosomes.

C is incorrect because genetic material is not present in any vacuoles.

D is the correct answer because as stated above, Strand A is a DNA strand and so it will be found in the nucleus!

Hope this helps!

The complete sentence about why Earth's atmosphere is important to live things is given below:

The gases that surround the Earth make up the atmosphere. It gives us air to breathe, protects us from the Sun's damaging ultraviolet (UV) radiation, traps heat to warm the globe, and lessens the dramatic temperature changes between day and night, all of which contribute to making life possible.

In addition to providing us with the oxygen we need to survive, it shields us from dangerous UV solar radiation. Without it, the pressure needed for liquid water to exist on the surface of our planet would not be possible.

Therefore, the correct options are B, oxygen, D, water, and E, sun.

hope this helps im not really sure if its right or not <3

Answer:

Both A and B.

Explanation:

(1). The amount of organisms born must be more than the number who have died.

This should always be the case with any animal population. If the death rate is higher than the amount of organisms born, the population would eventually become extinct if nothing is done.

(2). Available resources in the habitat exceed the number of organisms in the population.

If the amount of resources in the habitat are less than the entire population itself, the population would eventually use up all those resources and would become extinct.

(3). The death rate exceeds the birth rate for the population.

If the death rate exceeded the birth rate, the population would die off overtime.

Genetic variation is the raw material for natural selection. It is part of evolution.

Evolution refers to descendence with modification, which especially happens due to natural selection.

Natural selection is the process of differential survival and reproduction of the fittest (more adapted) organisms.

Genetic variation is the raw material used by evolution to 'select' the phenotypically more adapted organisms in a given environment.

Diet which includes food directly from the source (grain based diet) will increase the number of humans that Earth can ultimately support.

This is referred to as the type of food an organism eats. It is however said that grain based diet is the best.

This is as a result of this type of diet being able to increase the number of humans that Earth can ultimately support. Meat consumption may however cause a decrease in this scenario.

Locomotion in paramecium is through metaboly and ciliary beating.

Locomotion refers to the ability to love from place to place.

Paramecium is a unicellular eukaryotic organism found in aquatic habitats.

Paramecium performs locomotion by two methods

Metaboly is a type of movement where the paramecium squeezes itself through narrow passages by changingthe structure of its protoplasm.

Metaboly is a temporary and slow locomotion im paramecium.

Ciliary beating is a fast method of locomotion in paramecium through forward or backward beating of the cilia.

The correct answer is  All members of a biological species have in common is that they can interbreed and produce fertile offspring.

It has a common gene pool, can interbreed to produce new offspring, can produce fertile offspring. It has a collection of gene variants. Species are separated from each other by zygotic events that cause differences in them.

The biological species have all in common that they can produce fertile offspring. For example Sturnella neglecta,  Sturnella magna.

Answer: D . some species react by mutating

Explanation:

"traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution."-Adaptation | National Geographic Society

Certain animals are able to adapt to changing environments because some species have greater variation in their genetic makeup. Therefore, option A  is correct.

Adaptation refers to the process by which organisms change over time to better suit their environment and increase their chances of survival and reproduction. Adaptations can take many forms, including changes in behavior, physical characteristics, or internal processes.

Adaptation is an important concept in evolutionary biology, as it is a key mechanism by which organisms become better adapted to their environment over time.

Certain animals are able to adapt to changing environments because some species have greater variation in their genetic makeup. Therefore, option A  is correct.
