Answer:

Plastics are derived from natural, organic materials such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds and needs to be processed before it can be used. The production of plastics begins with the distillation of crude oil in an oil refinery.

Explanation:

Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.

They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.

Answer:

because if there's more biodiversity/animals there would be many animals that could take over  another animal role in the ecosystem incase of extinction unlike when there's fewer biodiversity or animals meaning fewer replacements and unbalance in the ecosystem

Answer:

Nervous tissue can generate and conduct electrical signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

    The other options are not true because nerve tissue does not generate or conduct thermal or chemical signals to perform its function.

Part 1: electrical

Part 2: A, B, E

Answer:

They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.

Example: Dominant blue flower (Bb)  mixed with recessive yellow flower (bb)

        B            b

b       Bb          bb

b       Bb          bb

There is a 50/50 chance the offspring will be either blue or yellow

The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.

A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."

The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.

When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.

Thus, in this way, phenotype is dependent on genotype of the organism.

The properties of carbon atoms allow carbon to easily bond to other carbon atoms to form very small and complex macromolecules with unique structures and special functions.

Macromolecules may be defined as biological molecules which carry a large number of atoms in them.

A Carbon atom has the unique ability to form bonds with other atoms of carbon, hydrogen, oxygen, nitrogen, etc. to form small or large and complex molecules.

Therefore, the properties of carbon atoms allow carbon to easily bond to other carbon atoms to form very small and complex macromolecules with unique structures and special functions.

Answer:

5. C. C6H12O6 + O2 ➡️CO2 + 02 + ATP

6. D. It breaks down glucose to form ATP.

7. D. All autotrophs are producers

8. D. All 4 statements are correct.

9. False

10. False

Explanation:

The process of photosynthesis converts carbon dioxide and water into glucose and oxygen while the in the process of cellular respiration, glucose and oxygen are converted to water and carbon dioxide and ATP is formed.

In photosynthesis, glucose is formed while in cellular respiration ATP is formed. The process of forming ATP and glucose are ways in which energy is cycled and oxygen cycle occur in the atmosphere. Energy can not be recycled but it is rather used. Only green plants carry out photosynthesis. Autotrophs are known to be primary producers.

Answer:

Explanation:

as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration

Answer:

b) skin cells go through the process of mitosis to make new identical cells.

Explanation:

The skin is the largest organ in the human body; it forms a protective barrier that keeps out external pathogens, and is integral to waste removal. When the organ is injured, damaged cells initiate an immune response, while healthy cells nearby begin to replicate.

This type of cell replication involves somatic cells and results in the diploid number of chromosomes called mitosis. Skin cells are somatic- they contain all 24 pairs of human chromosomes. During replication, the chromosomes are unwound, and copied- then, the newly copied chromosomes separate into two identical daughter cells with the same chromosome number.

What goes into the cell? Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes. Glucose enters the body when an organism eats.

Explanation:

Hope this helped, Thanks :)

Cellular respiration has been the chemical process that uses glucose to produce energy. Oxygen is the reactant of the process that comes from the air (breathing) produced by photosynthesis.

Cellular respiration has been defined as the process vital for living organisms that use oxygen and sugar molecules to produce energy to drive the activities and functions of the body. The reactant of the process includes glucose and oxygen gas.

Oxygen and sugar are known to be the product of the photosynthetic reaction that uses carbon dioxide and water. The oxygen gas is present in the atmosphere and enters the body through breathing.

Therefore, oxygen acts as a reactant in cellular respiration that comes from the breathing process.

Answer:

B. They do not have a rigid outermost layer.

Explanation:

Several organisms, including bacteria and eukaryotes are heterotrophs- this means that they obtain energy through breaking down organic molecules like sugar, and amino acids made by producers.

Animal cells are eukaryotic; all eukayoted may be single-celled, or multicellular, and contain a nucleus containing genetic material along with membrane-bound organelles in their cytoplasms. Animal cells do not contain rigid cell walls, unlike other eukaryotic cell types like plant cells.

Cellular respiration

Explanation:

This is because if you see Photosynthesis is used for plants to get a food source from the Sun. Osmosis is the movement of chemicals from a less converted membrane to a more.

Carbon dioxide increases temperatures, extending the growing season and increasing humidity. Both factors have led to some additional plant growth. However, warmer temperatures also stress plants. With a longer, warmer growing season, plants need more water to survive.

Explanation:

Answer:

C. The salt is dissolved by the water

Explanation:

When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

Answer:

Enzymes bind with chemical reactants called substrates there may be one or more substrates for each type of enzyme I beleivedepending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products the enzyme's active site binds to the substrate.

Explanation:

Hope this helps.

Answer:

When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process
