Describing Water Molecules Which of these statements would be true if the water molecule was linear instead of bent? Check all that apply. Water molecules are polar. Water molecules are nonpolar. Water molecules undergo hydrogen bonding. Water molecules have a linear geometry. Water molecules have a bent geometry.

Answers

Answer: These are the correct answers...

-Water molecules are polar

-Water molecules undergo hydrogen bonding

- Water molecules have a bent geomtry

Hope this helps whoever needs it

The statements that are correct about water molecules are:

Water molecules are polar. Water molecules undergo hydrogen bonding.Water molecules have a bent geometry.Water is polar molar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule means that a water molecule has two poles - a positive charge on the hydrogen pole (side) and a negative charge on the oxygen pole (side).Water molecules forming hydrogen bonds with one another.Water has a bent shape is that the two lone pair of electrons are on the same side of the molecule.

What is the initial source of the energy in all food webs and food chains? Explain please

Answers

Answer:

The sun

Explanation:

The sun provides the light energy that plants need in order to produce glucose the animals gain after eating the plants or the animals that ate the plants.

The initial and ultimate source of the energy in all types of food webs and food chains is the Sun.

What is the primary source of energy?

The Sun is the major source of energy for living organisms and the ecosystems of which they are a part on the Earth. Producers are the organisms of the food chain which produce energy such as plants, algae, and cyanobacteria. These organisms use the energy from sunlight to make organic matter from that of carbon dioxide and water molecules. This establishes the beginning of energy flow through almost all the food webs.

The light which is coming from the sun allows the green plants that is the producers to manufacture chemical energy which fuels all the cellular functions. In turn once the plants are eaten, this chemical energy and nutrients are transferred to the consumers and to other higher organisms.

Which of the following is true:

- Since the active site has a specific shape it can only fit one substrate.

- The active site can fit any type of substrate.

- Nothing can fit or bond with the active site of an enzyme.

Answers

Answer: Since the active site has a specific shape it can only fit one substrate.

Explanation: I took one for the team on Ed puzzle.

Since the active site has a specific shape it can only fit one substrate. The correct option is A.

What is active site of enzyme?

The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction in biology and biochemistry.

The active site is made up of amino acid residues that form temporary bonds with the substrate (binding site) and residues that catalyze the substrate's reaction (catalytic site).

The active site of an enzyme is the specific region of the enzyme where a substrate binds and catalysis or chemical reaction occurs.

It is a protein structural element that determines whether the protein is functional when subjected to an enzyme reaction.

A holoenzyme is a fully active enzyme that is made up of a protein portion (apoenzyme) and a cofactor.

Thus, the correct option is A.

What are the parts of the compound light microscope

Answers

: The three basic, structural components of a compound microscope are the head, base and arm.

•Head/Body houses the optical parts in the upper part of the microscope.

•Base of the microscope supports the microscope and houses the illuminator.

•Arm connects to the base and supports the microscope head.

The head, base, and arm are the three fundamental structural elements of a compound microscope.

Thus, Head/Body houses the optical components in the microscope's upper section. The base of the microscope holds the illuminator and supports the microscope.

Arm supports the microscope head and is attached to the base. The development of the field of microbiology brought into focus the significance of the identification, seeing, observation, and comprehension of microbes, including their structural morphologies and mechanisms.

The study of tiny creatures and agents that can only be seen and investigated under a microscope falls under the purview of microbiology.

B. The insects actually use their wings to hover slightly above the waters surface and they only skim it with their feet

C. The insects feet are non- polar so they are repelled by the polar water molecules and are pushed away from the waters surface

D. The insects are small enough to see the individual water molecules so they are able to step carefully from one molecule to the next

Answer:

A. Insects are light enough so that they do not break the h bonds holding the water molecules together

Explanation:

The insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.

What is surface tension?

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.

Surface tension is responsible for the shape of liquid droplets and the surface tension of water is about 72 mN/m at room temperature.

Water has a tremendous amount of surface tension due to which small mass distributed effectively on its surface.

Surface tension is represented by the symbol T.

Therefore,the insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.
