Answer:

Binocular vision

Explanation:

Vision can be explained as an ability to see directly some things that can be a threat or of benefits . It can also be explained as the ability to sense or perceive threat or danger, or something good.

In this case, binoculars vision is a situation of sensing threats or dangers from a very distant place through the help of the brain. Most times, the brain will be able to sense dangers from the interpretation it gathered from what it saw earlier, before the person is involved in the act.

Which of the following best expresses the concept of natural selection?
A) differential reproductive success based on inherited traits
B) inheritance of acquired characteristics
C) change in response to need
D) a process of constant improvement, leading eventually to perfection
E) survival of the fastest

Answers

Answer:

The correct answer is - option A. differential reproductive success based on inherited traits

Explanation:

Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.

The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.

Thus, the correct answer is - option A. differential reproductive success based on inherited traits

Due to genetic changes and the environmental conditions when the organism adapts itself to the current situation for survival is called natural selection.

Natural selection means that the organism that survived over another have better traits and characteristics for adaptation.

The correct answer is:

Option A. differential reproductive success based on inherited traits.

This can be explained as:

A particular type of trait carried by an organism that is better for adapting to survival than the other organism carrying less favorable trait will have a better chance of survival and their reproductive success will be much higher.

Based on the inherited characteristics the natural selection will be based on reproductive success.

Differential reproductive success is an analysis in which comparison is done among the organism that survived and those that did not.

Comparing their traits and characters can give an idea about the factor affecting the selection.

Therefore, differential reproductive success based on inherited traits best expresses natural selection.

Explanation:

The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.

The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

Answers

Answer:

In the ocean

Explanation:

Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence  in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.

hope it helps you..

The place where there would be a higher occurrence of the full body plate trait would be:

In the ocean

Based on the given question, we can see that when the ecological divergence which helps the full body plate type to have a higher occurrence in the lake because there is a need for attention.

With this in mind, we can see that in the ocean, there is the higher chance for the full body plate because of the absence of predators and the abundance of resources in the ocean.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption

Answers

Answer:

constructive interference

Explanation:

when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.

When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.

What is the constructive interference?

Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.

When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.

Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.

Therefore, constructive interference  best describes what happens if two waves meet and build on each other.

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.

Answers

Answer:

A. The whale is heterotrophic.

Explanation:

The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.

Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
