A stem cell turning into a skin cell

Explanation:

As usually the process of cell division involves the idea of the cell arising from other cells and mostly stem cells undergo mitosis which again is a process of cell division hence demonstrating that the cell arise from other cells either through division.

Answer:

living, components can likewise influence an organic entity's capacity to make due in an environment. They incorporate food accessibility, rivalry with different life forms, plant cover accessibility, predation, sickness, parasitism, swarming, territory discontinuity and the presence of human populaces. An absence of trees can influence populaces of birds or other arboreal organic entities, which may depend on tree cover for settling and stowing away from hunters. Some biotic elements influence abiotic factors also, for example, plants that become taller than contending plants and square daylight, or an absence of disintegrating natural matter or nitrogen-fixing microorganisms that prompts low nitrogen levels in the dirt.

Explanation:

Answer 1: The crinkly shiny lining inside chip and snack bags is made out of mixed material, including aluminum and plastic. These materials cannot be separated to be recycled and must go in the trash. Simply crush up the material in your hand, and if it bounces back into it's shape, it's not recyclable. ...

Answer 2: Here are 10 ways to reuse potato chip bags.

At picnics or parties, use for most any food that doesn't need a lid container.

Use in car trunk to store either clean or dirty rags.

Use to wrap up breakables for transporting.

Put babies dirty diapers, especially throwaways when you are going to use a public trash can.

Use to store or carry baseballs. You can get about 12 hardballs in a large bag or 6 softballs.

Use the bag to collect berries, pine cones, or any other little treasures you find on your nature walks.

Use to carry your caught fish home.

Use to bury your desceased pet parakeet, fish, gerbils or hamster. Just wrap them up in a bag and bury.

Use as a trash bag for your vehicle.

A large empty potato chip bag will make 2 one time picnic table place mats.

So don't trash your chip bag. Reuse It.

Answer:

Earth, both on land and in water. Wherever they

live, plants provide food and oxygen to the

creatures that live nearby – including humans!

In this activity we will examine both a

terrestrial (land) plant and an aquatic (water)

plant. They have many things in common, but the

ways they get air, food and water change along

with the environments in which they live.

Agriculture is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets. Agriculture provides most of the world's food and fabrics.

Answer:

The Circulatory System

Explanation:

Answer:

The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

Answer:

D or B?

Explanation:

Answer:

When strand slippage occurs during DNA replication, a DNA strand may loop out, resulting in the addition or deletion of a nucleotide on the newly-synthesized strand. ... But if this does not occur, a nucleotide that is added to the newly synthesized strand can become a permanent mutation.

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Answer:biotic factors

Explanation:

They are living

Food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Biotic and abiotic factors make up ecosystems in which biotic factors are living things within an ecosystem such as plants, animals and bacteria, while abiotic are non-living components such as water, soil and atmosphere.

An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, the abiotic factors are temperature, light, and water. In a marine ecosystem, the abiotic factors are salinity and ocean currents. Abiotic and biotic factors work together to form a unique ecosystem.

Biotic components are living things that have a direct or indirect effect on other organisms in the environment such as animals, and microorganisms and their waste materials.

Thus, food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Answer:

energy pyramid

Explanation:

An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain.

The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

Answer:

I believe it would be mitosis.

Explanation:

Answer:

Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population. Once such a gene is generated, bacteria can then transfer the genetic information in a horizontal fashion (between individuals) by plasmid exchange.

Explanation:

The air pressure descends as we ascend. In other words, they are inversely proportional.

The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.

Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.

A barometer is an instrument that is designed for measuring the changes in air pressure.  

Hence the option 3 is correct.

Answer:

organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
