Answer:
[tex]\boxed {\tt 3}[/tex]
Explanation:
An element only has one type of atom and cannot be broken down by chemical means.
Let's analyze the answer choices.
1. This has two types of atoms, so it cannot be an element. It has more than one type of atom.
2. This has two types of atoms that are bonded together. It cannot be an element because there is more than one type of atom and the bonds can be broken.
3. This has one type of atoms, so it is an element.
Therefore the best answer choice is 3.

What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?
Answers
Answer:
Please mark as brainliest!!!
Explanation:
Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.
It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.
Which component of nerve cells contains the nucleus? (1 point)
dendrite
axon
neuron
cell body
Answers
The answer is the cell body
Explanation:
The nucleus is the main control center, and the cell body is very gooey on the inside so the cell wants to protect the nucleus so we can live.
The nucleus is present in the cell body.
Nerve cell:Nerve cell is a basic unit of communication. Each nerve cell contains axon, cell body, dendrites and terminal branches. There are about 85 to 200 billion neurons present.
Neurons are surrounded by a cell membrane.Neurons have a nucleus that contains a gene.It also have cytoplasm, mitochondria and other cell organelle.Neurons are of different types:
Unipolar neuronBipolar neuronMultipolar neuronNeurons are the chemical messenger. They contain nucleus which contain genetic material. Mitochondria produces energy. Neurons contain specialized structures and chemicals. They contain some specialized structures (synapse) and chemicals called neurotransmitter.
Therefore, The nucleus is present in the cell body.

What do biogeochemical cycles represent?
Answers
The biogeochemical cycle of water, or the hydrological cycle describes the way that water (Hydrogen Dioxide or H 2 O) is circulated and recycled throughout Earth’s systems. All living organisms, without exception, need water to survive and grow, making it one of the most important substances on Earth.
hope that helps
Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.
What is Biogeochemical cycle?A biogeochemical cycle is defined as the path by which a chemical substance cycles through the biotic and abiotic compartments of the Earth where the biotic factor is the biosphere and the abiotic factors are the atmosphere, hydrosphere and lithosphere.
Nutrients cycle occur through organic components as well as abiotic components. In biosphere the term bio refers to biotic components while 'geo' refers to abiotic components. Therefore, nutrient cycles in nature are called biogeochemical cycles.
Thus, Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.

Which domain includes organisms that are called extremophiles (organisms which live in extreme environments)?
Answers
Answer: archaea
Explanation:
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
Archaea domain includes organisms that are called extremophiles (organisms which live in extreme environments).
What are the characteristics of archaea?Archaea is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotes. Archaea were initially classified as bacteria, receiving the name archaebacteria.
The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.
If there is an overgrowth of another organism called Archaea, then the symptom picture can be very different. There can still be bloating, abdominal pain and cramping, but Archaea usually cause constipation, not diarrhea.
