Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.

Answer:

moths would begin becoming lighter as the pollution is reduced

Explanation:

The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.

The color of the Moths will become lighter as a result of this due to the effect

pollution has on its color.

Industries and factories make use of fuel and when it is burned in generating

sets and other equipment it produces the compound known as Nitrogen

oxide.

The Nitrogen oxide has a brownish color which goes into the atmosphere

where the moths fly in  thereby contact with the gas darkens the color  to

shades of brown. A reduction in the discharge of the gas will lead to it

becoming lighter.

hydrogen and oxygen snsnsn

The oceans are primarily composed of carbon and hydrogen elements.

An element is a substance that cannot be broken down into a simpler format. They are distinguished by a unique atomic number. The elements are organized by their atomic number in the periodic table, which highlights elements with similar properties.

The six elements found in all organisms are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur; collectively called biological elements and shown as the acronym CHNOPS. These elements can bond with each other as well as other elements to create molecules.

Four elements—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up 96% of living matter. Most of the remaining 4% of an organism's weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K).

Answer:

The correct answer is - nitrogen fixation.

Explanation:

In soil formation microbes play an important role as they help in providing important compounds such as nitrogen by the process of nitrogen fixation that is used by the plants.

Nitrogen-fixing organisms mostly bacteria are free-living but some live in a symbiotic relationship with plants such as Azobacter or with other organisms such as Rhizobium.  

Answer:

Cell-surface receptors are involved in most of the signaling in multicellular organisms. There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.

Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.

Receptors are proteins, typically cell surface receptors, that bind to ligands and cause immune system responses.

Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.

Insulin receptors bind insulin, dopamine receptors bind dopamine, nerve growth factor receptors bind nerve growth factor, and so on.

Thus, due to this, receptors are needed for cell signaling.

Answer: A wedge is basically an incline plane. Often portable used for many purposes

Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.

In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.

The wedge works on the principle of an inclined plane.

The Door Stop Is an example of one,

Answer:

Skull three

Explanation:

the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature

It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.

As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.

It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.

Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.
