This tissue’s function is to transport sugars from the leaves to the other areas of the plant.

When there are more than two alleles for a trait, these alleles are independently assorted to the next generation and express their characteristics in the next generation's offspring and are called as multiple allelism.

The expression of the trait is determined by the nature of the trait, such as when some traits have only two alleles and one is completely dominant over the other, whereas in other traits, the alleles combine to express the effect. But some traits have more than two alleles, and they combine to express the trait, such as the skin color and the hair color of a human.

As a result, when there are more than two alleles for a trait, these alleles are independently assorted to the next generation and express their characteristics in the next generation's offspring.

The answer is depth and type of fluid. Type of fluid essentially means its density. Denser fluid exerts more pressure compared to less dense fluids. Additionally, the bigger the depth in the fluid, the more the pressure due to the column of the fluid above. The following formula is used to calculate this pressure of a static fluid;

Pstatic fluid = ρgh      where;       

ρ = m/V = fluid density

g = acceleration of gravity

h = depth of fluid

Photosynthesis and respiration are the two processes that help cycle carbon and oxygen through ecosystems.

C Photosynthesis and respiration.Photosynthesis is the process by which plants and some other organisms convert light energy into chemical energy in the form of glucose. This process uses carbon dioxide and water to produce glucose and oxygen. Respiration, on the other hand, is the process by which organisms break down glucose and release energy, carbon dioxide, and water. Together, photosynthesis and respiration help cycle carbon and oxygen through ecosystems.

Answer: Indoor air pollutant

Air pollution can be defined as contamination of atmospheric air by wastes, which can occur in solid, liquid and gaseous form. These pollutants can affect health of humans, plants and animals. Radon is a colorless, and odorless gas. It is a potential air pollutant. It is a dense gas which sinks in the air. It is often found at the basement of homes, especially in the areas where shale and boulders are present in the soil. Radon is produced as a result of radioactive decay of radium in the soil. Radon gas gets attach to the dust and other particles present in the air. It enters inside the lungs, produces alpha and beta radiation that damages DNA, and results in lung cancer.  

Answer:

The correct answer will be- He showed that transforming material was DNA in organisms.

Explanation:

Oswald Avery and colleagues worked on the experiments of Griffith on the transformation process and showed that the transforming material was DNA in Griffith experiment.

They grew the cultures of heat-killed S (virulent) bacteria and added DNases, RNases and proteases to the culture plates. Then R (avirulent) bacteria were added to the cultures. The S bacteria were not found in the cultures with DNases enzymes as DNases denatured the DNA molecule, so bacteria were not transformed.

This showed that DNA is the transforming material in the Griffith experiment.

The actin and myosin filaments in a muscle contract with enough force to produce a contraction. They don't hold each other still while pulling inward.

Myosin heads on myosin filaments interact with actin filaments during muscle contraction.

Actin filaments are pulled inward by the myosin heads, which are then released and reattached farther down the filament in a cycle. The sliding filament mechanism is the name given to this phenomenon.

Myosin heads join actin filaments in cross-bridges as a result of ATP hydrolysis.

Thus, The actin and myosin filaments in a muscle contract with enough force to produce a contraction. They don't hold each other still while pulling inward.

Answer: the correct answer is D) Mendel is considered the “father of genetics.”

Explanation: I took the test. Hope this helps! Have a good day!

Answer: D. H₂0

Calvin-Benson cycle is a set of chemical reactions that takes place in chloroplast during the process of photosynthesis. This is a light- independent cycle as the light energy is already trapped in light dependent cycle of photosynthesis. It utilizes NADPH and ATP products of light dependent reactions for synthesis of trios sugar glyceraldehyde-3-phosphate as product of Calvin-Benson cycle.

Final answer:

The steps involved in ecological succession in an area completely destroyed by a catastrophic event, such as a volcano, are: 1) Pioneer species, such as lichen and moss, enter the soil-less area. 2) Pioneer species help break down rocks present to form soil. 3) Grass species move into the area. 4) Herbaceous plants and small shrubs enter the area. 5) Small trees and evergreens become established. 6) Climax community of deciduous hardwood tree species becomes established.

Explanation:

After a volcanic eruption, ecological succession begins with pioneer species like lichens, which help form soil for other plants. Herbaceous plants and grasses follow, after which small trees and evergreens establish, leading eventually to a climax community of hardwood tree species.

Phospholipids are the component of membrane contains a hydrophobic region and acts as the primary barrier to most foreign substances.

A typical monomeric globular protein has a single, sizable, interconnected hydrophobic region that makes up around 60% of the solvent-accessible surface area. This region is generated from the faces of apolar atoms. The distribution of acyl chains and sterols in the hydrophobic area affects membrane stiffness and fluidity.

The primary constituents of the bilayer of phospholipids that composes the plasma membrane. Because they are amphipathic, or have both hydrophilic and hydrophobic areas, they are well suited for this function.

Thus, phospholipids are the component of membrane contains a hydrophobic region and acts as the primary barrier to most foreign substances.

Having the ability o remember how to ride a bike is an example of a long term memory.  This is procedural memory; knowing how to do something, having the skills and the formation of simple associations. These skills are able to be recalled at any time.

Answer: Procedural

Procedural memory helps people understand how stuff works. It is primarily involves in knowing new motor skills like learning how to ride a bike or play a piano. The brain begin building and assigning interneuron pathways for cerebellum and basal ganglia to outflow muscle information to the legs or hands developing motor coordination.

Moreover, procedural memory is part of the long-term memory that is responsible for storing information on how to perform certain procedures.

Final answer:

Essential nutrients necessary for human nutrition include carbohydrates, proteins, lipids, water, vitamins, and minerals. These are categorized into macronutrients needed in larger amounts and micronutrients required in smaller amounts but are vital for body processes like tissue maintenance and blood clotting.

Explanation:

The essential nutrients for proper human nutrition include six major classes: carbohydrates, proteins, lipids (fats), water, vitamins, and minerals. These substances are deemed essential because they cannot be synthesized by the body and must be obtained from food.

Carbohydrates, proteins, and lipids are considered macronutrients, which the body requires in larger quantities for energy and body building. Conversely, vitamins and minerals are categorized as micronutrients, needed in smaller amounts but crucial for various body processes, including maintaining connective tissue and enabling blood clotting with the help of vitamins such as vitamin A and vitamin K, respectively.

It is important to note that while the body cannot store micronutrients, they must be consumed regularly to support bodily function. Vitamins and minerals are critical for ensuring regulation and good health, aiding in processes such as maintaining a stable nervous system and blood clotting.

RNA uses uracil in place of thymine, found in DNA, and has a ribose sugar instead of deoxyribose.

RNA contains the nitrogenous base uracil instead of thymine, which is found only in DNA. This means that during protein synthesis, adenine will always pair up with uracil in RNA, mirroring the pairing of adenine and thymine in DNA. Additionally, RNA includes the pentose sugar ribose, whereas DNA contains the pentose sugar deoxyribose, which has one less oxygen atom compared to ribose. The structural difference between uracil and thymine is that uracil is an unmethylated form of thymine, which is crucial for RNA's function in protein synthesis.
