Answer:
the cell is the answer
Explanation:
the smallest unit component that all living beings must have is the cell. In fact some living things can be just one cell. Every living being comes from cells, is made up of one or more cells, and cannot be considered a living organism without at least one
Answer:
Non-living, it's atoms, but the smallest unit component that all living beings that they must have is the cell. It is a proven fact some living things can be just one cell. Every living being comes from cells, is made up of one or more cells, and cannot be considered a living organism without at least one.

chlorine gas (CI) is toxic and sodium (Na) is explosive? yet, together they make common table salt. why do they form a chemical bond?
A)together these two elements form a more stable molecule
B)sodium is a non metal and chlorine is a metal -nonmetals and metals always form a bond
C)chlorine is on the left side of the periodic table in group 1 and these elements always form bonds
D)chlorine has two protons and they transferred to sodium to form the salt molecule
Both ions have complete valence shells and are energetically more stable. I’d assume D because the protons need to transfer.

Two photographers take time-lapse photos of the night sky. One of them is at the equator. The other is at the south pole. Which photo will show stars that never rise or set? Explain
Answer: South pole.
Explanation:
The equator is filled with non-circumpolar stars which means the stars sets in the sky. The north and south pole is full of circumpolar stars which means they never set.
If two photographers take time-lapse photos of the night sky with one being at the equator and the other at the south pole, the photo by the photographer at the south pole will show stars that never rise or set.
The stars that never rise or set is known as the circumpolar stars and are usually found close to either of the earth's poles - north or south pole.
This means that the photographer at the equator which is an equidistance from the two poles will not be able to capture the circumpolar stars.

How can an abiotic factor like temperature impact the population size of an ecosystem
Answer/Explanation:
Abiotic factors are non-living factors such as temperature, light, water, humidity, acidity, etc.
They strongly impact the ability of organisms to grow and successfully reproduce, and therefore affect the diversity of organisms in any given area.
If the temperature, light, and water availability (for example) are optimal, then species of plants will be able to grow successfully. This increases their populatuion size. Not only that, but it also provides a greater food supply for the animals that eat the plants, so their population will also grow.
draw a well labelled diagram of a leaf structure and explain how the stomata ,the cuticle and the vascular bundle works
Answer:
A well labelled diagram of a leaf structure
Explanation:
Answer:
Vascular bundles are a collection of tube-like tissues that flow through plants, transporting critical substances to various parts of the plant.The cuticle reduces the rate of water loss from the leaf surface.Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf.Diatoms are one of the most common types of phytoplankton in marine habitats. Like plants, diatoms contain chlorophyll and produce glucose from which of the following?
CO2 and O2
CO2 and H2O
O2 and ATP
ATP and H2O
Answer:CO2 and H2O
Explanation:
Diatoms produce glucose from CO2 and H2O.
The sun is the only source of energy in the ecosystem. Plants can trap this energy from the sun through the process of photosynthesis. Photosynthesis is the process by which green plants use energy from the sun to combine carbon dioxide and water to form glucose.
Hence, like plants, diatoms contain chlorophyll and produce glucose from from CO2 and H2O.

Which of the following statements is true?
A) The number of electron shells in an atom is called the atomic number.
B) Boiling and melting points are chemical properties.
C) A molecule of oxygen can have atoms of carbon in it.
D) Elements are substances made of only one type of atom.
Answer:
D) Elements are substances made of only one type of atom.
Explanation:
The only correct choice from the ones given is that "elements are substances made of only one type of atom".
Elements are distinct substances that cannot be split up into simpler substances. Such substances consists of only one kind of atom. There are over one hundred elements known to date.
Atomic number is the number of protons in an atom. Boiling points and melting points are physical properties of a substances. A molecule of oxygen is made up of only oxygen atoms that have been covalently bonded together.Where is the main store of phosphorus ?
Answer:
Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts.
Answer:
The largest reservoir of phosphorus is in sedimentary rock. It is in these rocks where the phosphorus cycle begins. When it rains, phosphates are removed from the rocks (via weathering) and are distributed throughout both soils and water. Plants take up the phosphate ions from the soil.

Which members of an ecosystem are part of the energy flow? A. ONLY the living things in the ecosystem B. ONLY the nonliving things in the ecosystem C. Living and nonliving things in the ecosystem D. The energy flow is not dependent on any members of the ecosystem
Answer:
D. The energy flow is not dependent on any members of the ecosystem
Explanation:
The energy flow in an ecosystem is not dependent on any member of the ecosystem. It is the flow of energy through the food chain, energy is passed from members in one trophic level to members in another or the next trophic level. The flow of energy in an ecosystem is important because it helps in maintaining balance in ecology.

If the man did not eat during the bike ride, why do you think that his blood glucose
level never went below 4.5 mml/L
Answer:
Due to less conversion of glucose into energy.
Explanation:
If the man did not eat during the bike ride, his blood glucose level never went below because there is very little amount energy is used. If a person perform activities such as running and exercise etc, it requires more energy and for that more glucose is converted into energy and glucose level went down while on the bike ride very little amount of energy is needed and for that very little amount of glucose is converted into energy and the glucose level did not went below 4.5 mml/L.
