why is the circulatory system of insects not involved in the respiratory mechanism of insects?​

Answers

Answer 1

Explanation:

Insects do not have lungs, nor do they transport oxygen through a circulatory system in the manner that humans do. Instead, the insect respiratory system relies on a simple gas exchange that bathes the insect's body in oxygen and expels the carbon dioxide waste.

Unlike the closed circulatory system found in vertebrates, insects have an open system lacking arteries and veins. The hemolymph thus flows freely throughout their bodies, lubricating tissues and transporting nutrients and wastes.

Lipids, carbohydrates, and DNA all exist in human cells as long molecular chains. Which of the following describes how DNA differs from lipids and carbohydrates?
A. Only DNA has carbon Atoms
B. Only DNA is found in the cytoplasm
C. Only DNA is needed to create new cells
D. Only DNA contains genetic information

Answers

Answer:

D. Only DNA contains genetic information

Explanation:

DNA has the main function of carrying genetic information.

On the other hand, lipids and carbohydrates have the main functions of being energy sources.

Lipids are used for long term energy storage, while carbohydrates are used for quick energy.

DNA is different from lipids and carbohydrates because it contains genetic information, while the others don't.

So, the correct answer is D. Only DNA contains genetic information

state the importance of calcium and zinc in our body​

Answers

Answer:

Calcium is a mineral found in many foods. Almost all calcium is stored in bones and teeth to help make and keep them strong. Your body needs calcium to help muscles and blood vessels contract and expand, and to send messages through the nervous system. Calcium is also used to help release hormones and enzymes that affect almost every function in the human body.

Zinc, a mineral that people need to stay healthy, is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. The body also needs zinc to make proteins and DNA, the genetic material in all cells. During pregnancy, infancy, and childhood, the body needs zinc to grow and develop properly. Zinc also helps wounds heal and is important for our ability to taste and smell. Zinc is found in a wide variety of foods, and is found in most multivitamin/mineral supplements.

Knowing that greenhouse gases are contributing to climate change, how can we
reduce our carbon footprint, particularly in the United States? Could hydrogen
fuel replace fossil fuels in the future? Why or why not? Should the size of a person's
carbon footprint be limited by law? Why or why not?

Answers

Answer: I believe that developing more sustainable methods of living is one way we may lessen our carbon footprint. For example, more than half of the electricity produced in the United States is generated by polluting coal-fired power plants. And the single greatest producer of heat-trapping gas is power plants. Hydrogen fuel has the potential to replace fossil fuels in the future since it is one of the most plentiful elements in the universe, implying that humanity will not run out anytime soon. The extent of a person's carbon footprint should not be regulated by legislation since it would limit the items you are permitted to use and eat. Limiting your carbon footprint will just increase people's anxiety about the planet.

Another example: To lower our carbon footprint, we may cease using things that emit greenhouse gases, such as walking instead of driving, or we can stop purchasing products made in smokehouse factories. Hydrogen fuel might potentially replace fossil fuels since it is better for the environment. They may be used by more individuals, lowering their carbon impact. I believe that a person's carbon impact should be legally limited. This will cause people to consider more seriously the use of fossil fuels, which will have a significant influence on our ecosystem.

Another Example: More renewable gases might be used in the United States. We might enlighten homeowners about solar panels and how they save money while also being beneficial for the environment. To reduce gas pollution in the air, more electric automobiles at accessible rates are needed. The majority of hydrogen fuel will most likely be produced from natural gas using an energy-intensive and toxic process known as steam reforming. The methane is broken down into hydrogen and carbon monoxide using steam, high heat, and pressure. Electricity may be used to create hydrogen from water, and then carbon dioxide can be used to make alternative fuels to replace fossil fuels. People should be educated about renewable energy by the government. I don't believe it should be regulated because certain people may require more gasoline than others. People who do not have a reason to not utilize renewable energies should be limited, in my opinion. If people's usage of greenhouse gases is not limited, extra heat will still be trapped, causing the climate to warm.

Explanation:

We can reduce our carbon footprint, particularly in the United States

through promoting the use of clean renewable sources of energy.

What are Renewable sources of energy?

This form of energy are usually replenished through natural occurrences

such as rainfall, sunlight etc. They are usually clean and don't emit carbon

as in the case of non renewable sources of energy.

Hydrogen fuel has potentials to replace fossil fuels as it is carbon-free.

The size of a person's carbon footprint should be limited by law to ensure

that less carbon is emitted and sanctions are meted pout for those who

flout the law.

Ryland is setting up a cooler to store flowers for a big event. Which of the following is NOT going to contribute to ethylene build up in his cooler?

O Gas leaks
O Succulents and cacti
O Old flowers
O Ripening fruit

Answers

Answer:

Gas leaks

Explanation:

I don't know anything about biology but I know gas leaks aren't good for plants

The option that will not contribute to ethylene building up in Ryland's cooler would be gas leaks.

Ethylene plant hormone

Ethylene is an important hormone for plants that regulate processes such as leaf/fruit abscission, fruit ripening, and senescence.

Thus, keeping succulents and cacti, old flowers, and ripening fruit in the cooler would be a good recipe for ethylene building up in the cooler.

Gas leaks may not find its way into the cooler as long as it is closed.

Answers

Organisms that are multicellular, heterotrophic, eukaryotic, and devoid of cell walls are found in the kingdom Animalia.

Which creatures fall within the Animalia category?

All living things fall under the Metazoa, also known as the Kingdom Animalia. This kingdom lacks prokaryotes and protists (Kingdom Monera contains bacteria and blue-green algae) (Kingdom Protista, includes unicellular eukaryotic organisms).

As to why Animalia is a kingdom?

Kingdom Animalia is a taxonomic kingdom that includes both extant and extinct species of animals. Eukaryotic, multicellular, heterotrophic, without a cell wall, and largely motile describe the members of this kingdom. They all have numerous cells and are heterotrophs, which means they rely on food from other living organisms.
