What are fossil fuels?

Coal, oil, and natural gas are fossil fuels formed from the remains of dead plants and animals that were buried in sedimentary rock layers millions of years ago.

Over time, these organic materials are subjected to high temperatures and pressure, resulting in the transformation of organic matter into fossil fuels.

These hydrocarbons migrate through the surrounding rock over millions of years and accumulate in underground reservoirs, where they can be extracted and used as energy sources.

Fossil fuel formation is a slow process that requires specific geological conditions such as the presence of sedimentary rocks, high temperature, and pressure.

Thus, the correct option is B.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin
c. pilin

Answers

Answer:

b. tubulin

Explanation:

Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles

Tubulin protein is damaged at the nerve endings during mercury toxicity.

What do you mean by Mercury Toxicity?

Mercury toxicity occurs when an individual is highly exposed to mercury.

The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.

Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.

Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.

What is the direction of energy flow in an energy pyramid? How much energy is transfered from one step to another?

Answers

Answer:

- The flow of energy is from the lowest level (i.e., the base of the pyramid)  to highest levels

- Approximately 10 percent

Explanation:

The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. Each trophic level is characterized by organisms that play specific roles in an ecosystem, for example, photosynthetic organisms (producers) at the base of the pyramid which represent the source of energy for herbivores localized at a higher level. The amount of energy decreases as it moves to higher trophic levels, approximately 10 percent of the energy is transferred from a trophic level to the next level and the remaining energy is lost as heat.

What would happen to Earth's climate if we had no moon, and why?

Answers

Answer:

The tilt creates what we know as seasons and changing weather. Without the pull of the moon, this tilt would change.

Explanation:

Either the tilt would become extreme, leading to extreme and severe seasons, or the tilt would decrease, and we would see almost no seasons at all. The moon influences life as we know it on Earth.

Answer: Because It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

Determine the rate of oxygen consumption at each temperature for comparison. Then divide the higher rate by the lower rate to obtain the difference (ratio) between the two temperatures. Round your answer to the nearest 0.1. It can be concluded that mouse respiratory rate (increases or decreases) when temperature is lowered. In this experiment there was a fold difference in respiratory rate at the two temperatures.

Answers

Answer:

In mice rate of respiration increases as the temperature drops.

Explanation:

As the temperature decreases, the respiration rate also decrease because the body needs less oxygen for the production of energy. But in the case of mice, the rate of respiration decreases and the reason is the fear. Results showed that the respiration increased in mice as the decrease in temperature occur, caused due to the fear instilled in the mice towards cold temperature so in mice rate of respiration increases as the temperature drops.
