explain how the information in this diagram indicates that an oxygen atom could bond covalently to two hydrogen atoms to form water

Answers

Answer:

because when oxygen atom bonds with two hydrogen atoms they form water

Explanation:

A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.

Do you think there should be regulations on industries that make fertilizers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems? Why or Why not? Write at least five sentences defending your answer.

Answers

Given what we know, we can confirm that there should in fact be regulations on fertilizer manufacturers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems due to its negative effects on the ecosystems.

What is Nitrogen?Nitrogen is an element that is most often found in a gaseous state.It is color and odorless.It is found in the air, water, and almost everywhere else around us, but in low quantities. It can form toxic gases such as ammonia when in high concentrations in the air.

Why can it be harmful in excess?Excess nitrogen in water is very bad due to the effect on algae. Contrary to what we may initially believe, excess nitrogen can help algae to grow at very high rates.However, these algae blooms sap the oxygen from the water at increased rates and damage if not kill all other marine life in the area as a consequence.

Therefore, regulations should be in place for fertilizer manufacturers and farmers who use fertilizers to ensure that excess nitrogen does not reach water ecosystems due to its negative effects on the ecosystems.

how long does it take for a photon to travel through the convection zone

Answers

Answer:

50 million years

Explanation:

It can take a photon as long as 50 million years to travel all the way through the radiative zone. The convection zone surrounds the radiative zone. In the convection zone, hot material from near the Sun's center rises, cools at the surface, and then plunges back downward to receive more heat from the radiative zone.

How did the bombardment of Earth by solid particles affect its temperature

Answers

Answer:it affected it by being hot

Explanation:

snglekns

The bombardment of the earth by solid particles affects its temperature because the bombardments release heat and make the earth warmer, and due to this, the early earth was hotter.

What is the earth?

The Earth is the planet in the solar system that moves around the sun, and it has living plants and animals along with non-living substances such as soil, air, water, etc. Most of the earth is covered with water and the earth has various populations, biomes, and biodiversities, and all of this biodiversity is due to changes in climate and geography, which result in the presence of various animals.

Answers

Answer:

no it is not possible

Explanation:

bc when you do a punnett square brown hair is dominant so there is not a possible way for their child to have blonde.

yes it is, let’s say B - is for brown hair and b - is for blonde hair
to have blonde hair they would have to have a bb genotype meaning that if bob had the Bb genotype then sally and bob have a 1/4th chance of having a blonde haired child

"Pharmacodynamic interactions" are interactions in which substances directly affect one another's effects. Sedatives, for instance, typically potentiate one another.

Neurons are the cells of the nervous system the cell plants are branch-like structures like the roots of a plant, they contain absorb information using electrical impulses and transport it into different areas of the brain.

The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells.

Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.

The process that breaks down nucleic acids into nucleotides is hydrolysis. The correct option is d.

What is hydrolysis?

Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis.

When water is the nucleophile, the phrase is used generically to refer to substitution, elimination, and solvation processes.

Nucleo depolymerase is another name for nuclease. By cleaving the phosphodiester bond that connects the nucleotides in the nucleic acids, the nucleic acid is broken down into nucleotides.

Either an enzyme or a non-enzyme can cleave the nucleic acid chain. Since the initial step in the alkaline hydrolysis of a polynucleotide is the transfer of the bond from C5' of the subsequent nucleotide to C2' of the same nucleotide, a 2'-OH group is necessary.

Thus, the correct option is d.

Cell membranes are made up of a bilayer of phospholipids that are very selective about what substances can pass through.The table below shows the different types of molecules that can enter a cell. It compares the concentration on the outside to the inside of the cell, its relative size, and whether it is polar, nonpolar, or an ion. Determine how each molecule can pass into the cell. Is it by passive transport, active transport, or endocytosis? (3 points)​

Answers

Answer:

Answer: Oxygen = passive Carbon Dioxide = passive Fructose = Endosytosis glutamine = Active Sodium ion = Active Potassium ion = Active Protein molecule = Passive or Endocytosis

Explanation:

js trynna get points lol

The molecules can pass into the cell by passive transport, active transport, or endocytosis.

Molecule | Concentration Outside | Concentration Inside | Size | Polarity | Transport | Mechanism

Glucose High Low Small Polar Diffusion

Oxygen High Low Small Nonpolar Diffusion

Sodium High Low Small Ion Active transport

Chloride Low High Small Ion Active transport

Amino acids Low High Medium Polar Carrier-mediated transport

Large protein Low High Large Polar Endocytosis

Glucose and oxygen can pass into the cell by diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Glucose and oxygen are both small molecules, and they are both polar. This means that they can dissolve in the phospholipid bilayer of the cell membrane.

Sodium and chloride can pass into the cell by active transport. Active transport is the movement of molecules from an area of low concentration to an area of high concentration. Sodium and chloride are both ions, which means that they are charged particles. This means that they cannot dissolve in the phospholipid bilayer of the cell membrane. Instead, they need to be transported across the membrane by special proteins called ion pumps.

Amino acids can pass into the cell by carrier-mediated transport. Carrier-mediated transport is a type of passive transport that uses carrier proteins to transport molecules across the cell membrane. Amino acids are polar molecules, but they are larger than glucose and oxygen. This means that they cannot simply diffuse across the cell membrane. Instead, they need to be transported across the membrane by carrier proteins.

Large protein can pass into the cell by endocytosis. Endocytosis is a process by which the cell engulfs large molecules or particles. The cell membrane forms a pocket around the molecule or particle, and then the pocket pinches off to form an endocytic vesicle. The endocytic vesicle then fuses with a lysosome, where the molecule or particle is broken down.
