Pls answer ill give brainliest if its on top of your account tag

Answer:

The graph of the runner must include the point (3.25, 25). [Students may also respond that the graph has a positive, or uphill, slope at that point. This is because the runner is facing forward in the image, so he must be running from left-to-right.]

Answer:

Myelin sheath

Explanation:

Increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.

The Impulse may be characterized as an electrical signal that can be transmitted along a nerve fiber in response to an external or internal stimulus.

The Myelin sheath increases the rate of nerve impulses. This is because it insulates the part of axons and reduces the chances of any disturbance in between due to the assemblage of voltage-gated sodium channels.

Therefore, increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.

The plastic that absorbs energy from sunlight becomes shrink. The correct option is B.

Endocrine disrupting substances (EDCs) are among them; they have been connected to a number of diseases such as infertility, obesity, diabetes, prostate cancer, and breast cancer.

In addition to these problems, chemicals have also been related to issues of neurodevelopment, growth, and reproduction.

Chlorinated plastic has the potential to leak dangerous chemicals into the soil around it. These chemicals can then seep into nearby water sources, including groundwater, and the ecosystem.

The species that consume the water may experience a variety of potentially dangerous impacts as a result.

The plastic is exposed to sunlight, which oxidises it and converts the polymers into oligomers, extremely soluble organic molecules.

Plastic breaks down into smaller molecules and absorbs UV radiation from the sun, thus how quickly it decomposes depends on how much of it is exposed to sunshine. This process is known as photodegradation in science.

Thus, the correct option is B.

protein digestion begins when you first start chewing. there are two enzymes in your salvia called amylase and lipase. they most break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid enzymes called proteases break it down into smaller chains of amino acids

Answer:

Hydrogen emits and absorbs light at specific wavelengths, therefore if you're looking at a distant cloud that produces a certain spectrum

Explanation:

Answer:

Amino acids are molecules used to build proteins. All amino acids have a central carbon atom surrounded by a hydrogen atom, a carboxyl group (COOH), an amino group (NH2), and an R-group. It is the R-group or side chain that makes each of the 20 amino acids unique.

The endosymbiotic theory is important because it is currently the leading theory on the origin of eukaryotic and prokaryotic cells and why they are different.

Answer:

b and c

Explanation:

because active transport requires energy from respiration yet diffusion doesn't. Additionally, active transport molecules move against a conc gradient but diffusion molecules move down a conc gradient.

Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll.

Artificial chemicals may be defined as chemicals that are synthesized by the activity of humans and their processes.

The nanoparticles of titanium dioxide have the ability to increase the light-capturing potential of a surface, while a photovoltaic cell enables sunlight to be processed into usable electricity by exciting outer shell electrons on some metals. These substances also behave naturally and initiate the reactions in the reaction center present in the chloroplast.

Therefore, Chemicals like Titanium dioxide and photovoltaic cells are artificial chemicals that behave like chlorophyll functionally.

Answer: 256 bacterium.

Explanation:

suppose a bacterium would divide once in every half an hour, this means it would be double in half an hour.

therefore, a number of the bacterium after half an hour will be 1 x 2 = 2.

After one hour, we would have doubled the number of bacterium =2 x 2

= 4.

Also, in one and a half hours, it would become 4 x 2

= 8.

In 2 hours, it would be 8 x 2 = 16.

Also in two and half hours, it would  be 16 x 2

= 32.

In three hours, it would be 32 x 2

= 64.

In three and a half hours, it would be 64 x 2

= 128.

Funally, in four hours, the number of bacterium would have been multiplied to 128 x 2

= 256.

It takes just four hours for one bacterium to become 256 bacteria.

It should be noted that a bacterium will divide once in every half an hour. This implies that it'll be double in every half hour. Therefore, for an hour, there'll be 2 bacterium.

Since it doubles every half hour, in 2 hours, the value will be 16 bacteria. Therefore, the value in four hours will simply be:

= 16 × 16 = 256 bacterium.

Therefore, it takes just four hours for one bacterium to become 256 bacteria.

Greenhouse gases are certain molecules in the air that have the ability to trap heat in the Earth's atmosphere. Some greenhouse gases, like carbon dioxide (CO2) and methane (CH4), occur naturally and play an important role in Earth's climate. If they didn't exist, the planet would be a much colder place.

Answer:

All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has stayed in the atmosphere. Eventually, the land and oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years.

The changes in the carbon cycle impact each reservoir. Excess carbon in the atmosphere warms the planet and helps plants on land grow more. Excess carbon in the ocean makes the water more acidic, putting marine life in danger.
