Answer:
3.46 malls of helium
Explanation:
6.022 multiplied by 10, raised to 23. The number of atoms of helium is equal to 3.46, multiplied by 6.022 multiplied by 10, raised to 23. So the number of atoms Adams of helium will be equal to 2.0836, multiplied by 10, raising to 24 items. So we can say this is 3.46 malls of helium contains. So this is the final answer

Answer below:
Explanation:
A nonrenewable resource
Gold is a metal formed naturally. It is not so abundant in earth and become exhausted when consumed through excavation. Hence, gold is a non-renewable source.
What are renewable resources?Renewable resources are those which never ends as we consumed and can be recycled the used amount as well. Whereas non-renewable resources are no more when we exhausted the existing amount.
Solar energy, wind energy, hydrothermal energy etc are renewable sources. Metals, minerals, nuclear power, coal, fossil fuels etc. are examples of non renewable resources.
Gold is a natural metal used have significant importance and expensive. It cannot made from other substances. Hence, once all the existing gold are taken through mining there will be no more gold. Hence, it is a non-renewable resource.

A cell has lost the ability to release energy from glucose for the cell to use. In which of the following cell structures would this energy conversion be performed?
A nucleusnucleus
B mitochondriamitochondria
C cell membranecell membrane
D cytoplasm
Answers
This is because the mitochondria is the power house of the cell. And energy conversion happens in the mitochondria
A cell has lost the ability to release energy from glucose for the cell to use. Mitochondria would this energy conversion be performed. Therefore, option B is correct.
What is mitochondria ?Small structures found in the cytoplasm of a cell. Mitochondria produce the majority of the cell's energy and have their own genetic material that differs from the genetic material found in the nucleus.
The classic role of mitochondria is oxidative phosphorylation, which produces ATP by utilizing the energy released during food oxidation. In turn, ATP serves as the primary energy source for the majority of biochemical and physiological processes.
Our glucose molecules are transported by mitochondria through a process known as cellular respiration, which is essentially just a process of breaking down and converting glucose by combining oxygen with a glucose molecule.
Thus, option B is correct.

How does wind energy work?
Answers
Answer:
The basic working principle of a wind turbine is to convert the mechanical energy from the wind into rotational energy at the mill, then the rotation of the mill is used to rotate the generator, which will eventually generate electricity. This tool serves to change the low rotation of the wheel into high rotation.
Answer:
Wind power actually starts with the Sun. In order for the wind to blow, the Sun first heats up a section of land along with the air above it. That hot air rises since a given volume of hot air is lighter than the same volume of cold air. Cooler air then rushes in to fill the void left by that hot air and then a gust of wind happens.

True or false. All mollusks are cemented permanently to the ground
Answers
Answer:
False
Explanation:
Mollusks are living organisms that can move around often, like mussels and clams, and oysters.
The statement "All mollusks are cemented permanently to the ground" is definitely false.
What are mollusks?Mollusks may be defined as a type of living organism that has a soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.
According to the context of this question, mollusks also have the ability to move around their surrounding in order to facilitate their survival and interactions with other living forms. The characteristics of mollusks may include a mantle with a mantle cavity, a shell (except where lost), visceral mass, a foot, and a radula. The odontophore is in the mouth of most mollusks and it supports the radula.
Therefore, the statement "All mollusks are cemented permanently to the ground" is definitely false.

how would local residents of a place be affected by changes in the hydrosphere? (please help!!)
Answers
Answer:
Humans have impacted the hydrosphere drastically and will only continue to due so based on population needs. Global climate change, water pollution, damming of rivers, wetland drainage, reduction in stream flow, and irrigation have all exerted pressure on the hydrosphere's existing freshwater systems.
Hope it helps :)
Without hydrosphere the atmosphere will no longer be able to carry up the evaporated water, as well as pour down the water, leaving the biosphere to die.
It will affect all organisms because they won’t be able to survive with water.
