Answer:
Cells are limited by their surface area to volume ratio and they come in many different shapes. A cell's function is determined, in part, by its shape.
mark me as brainliest if u found it helpful
Answer:
Function
Explanation:
The shape of the cell, the organelles within it as well as how many of those organelles are present play a huge role in the cells function.
For example, muscles cells will have lots of mitochondria that are used for ATP production, needed in movement.
Lung cells will have ridges or groves in them that increase the cells surface area that make them much more effective at the diffusion of oxygen and carbon dioxide when breathing.
8. A student used a microscope to observe Elodea submerged in a solution. The student observed the cell cytoplasm pull away from the cell wall and clump together in the center of the cell. Which statement best explains why this occurred? Answer
Answer:
the cell was submerged in a hypotonic solution
Explanation:
The cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.
The plant elodea contains cell membrane and cell wall.
The cell wall is an elastic structure that is permeable to all molecules.
The cell membrane is however, selectively permeable.
For the plant to survive and function well, the fluid its submerged into must be isotonic or be able to maintain an osmotic balance.
When placed in a hypertonic solution, a strong concentration, exosmosis occurs.
Water flows out of the cell into its surroundings.
As a result, the vacuole shrinks and eventually pulls the cytoplasm from the cell wall.
Therefore, the cytoplasm pulled away from the cell wall because the elodea plant is submerged in a hypertonic solution.

Compare and contrast passive transport with active transport. Please have them in bulletpoints. Don't need to have full sentences.
Answer:
both
both are systems that move water nutrients into cells and remove wastepassive
movement of molecules DOWN the concentration gradient ( no cellular energy needed)maintains an equal balance between water, gases, nutrients, etc...active transport
uses ATP to pump molecules UP the concentration gradient ( requires cellular energy) moves molecules through the cell membrane against the concentration gradientdisrupts the equal balance made by diffusionI just bombed this test and i have 1 retake left. please help!!

What molecule was the director of the entire protein building?
Answer:
(Amino acids are the building blocks of proteins.) A type of RNA called transfer RNA (tRNA) assembles the protein, one amino acid at a time.
Explanation:
Amino acids are small organic molecules that are the building blocks of proteins. They have an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable part called a side chain.
What are proteins?Proteins are big biomolecules and macromolecules that are composed of one or more long chains of amino acid residues. Proteins can be classified as either macromolecules or biomolecules.
Amino acids are the fundamental components of proteins. They are tiny chemical compounds that contain an alpha (central) carbon atom that is coupled to an amino group, a carboxyl group, a hydrogen atom, and a variable component that is referred to as a side chain.
They are responsible for the majority of the work that occurs within cells and are necessary for the structure, function, and control of the organs and tissues found throughout the body.

Each parent gives one of these to the offspring to form a genotype.
Answer: Alleles
Explanation: Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
Each parent gives one ALLELE to the offspring to form a genotype.
An allele is a gene variant. which is inherited from each parent.
During fecundation, each parental gamete provides a different allele of a given gene/locus in order to form the genotype of an individual.
If both parents provide the same allele of a given gene/locus, then the individual is homo-zygous for that gene.
If both parents provide different alleles of a given gene/locus, then the individual is heterozygous for that gene.
In conclusion, one allele is inherited from the mother and the other allele from the father.

Recognize what energy is and how it is transferred throughout living systems.
Explanation:
Energy is the ability to do work. There are two main forms of energy, potential and kinetic energy.
Potential energy is the energy at rest in a body
Kinetic energy is the energy due to motion
Energy is usually transferred throughout living systems when are transformed from one form to another. For example, chemical energy in food produced by plants is taken by animals as food. They then convert the chemical energy into other forms of energy like heat energy which they use for their daily activities.What are some of the basic characteristics that scientists consider when classifying living things?
