Cell is the term that best captures the fundamental level of organization and structure found in all living things. the tiniest component of all living things, including cells and other body tissues, and the smallest unit capable of independent existence.
How do cells work, and what are they made of?They support the body's structure, consume nutrients from meals, transform those into energy, and perform certain tasks.
Who coined the term cell?In 1665, the cell was found by Robert Hooke. With the aid of a compound microscope, Robert Hooke examined a piece of wine cork and discovered tiny structures that looked like little rooms. His designation of these "rooms" as "cells" follows.

__are the molecules which are the result of a chemical reaction.
Galactose
Fructose
Reactants
Catalyst
Products
Answer:
Products
Reactants are the molecule you use in order to make the product at the end of the reaction
Catalysts simply help to make the reaction go faster
Galactose and fructose are just examples of molecules, in different reactions they could be either reactants or products.
Identify the true statements below.
The reaction of an exploding firework occurs at a faster rate than a burning candle.
The activation energy required for an exploding firework is less than the activation energy required for a burning candle.
Answer:
In the explanation-----
Explanation:
The first statement is correct since the gun explosive powder explodes since they light a fuse at first, and once the fuse reaches the end it explodes as a reaction. However, for a candle it relies on the lit fire. Wax is a tough and a longer substance to melt compared to a exploding firework.
For the activation energy for the firework, it uses that energy in a result of the fuse reaching the end and reacting with the gun powder.

how can limiting factors (density dependent and density independent) affect a population size?
In humans, oxygen and carbon dioxide are exchanged between the alveoli in the lungs and the blood in the circulatory system. Which of the following processes allows for the exchange of these gases in the human body?
osmosis
simple diffusion
active transport
facilitated diffusion
Answer:
Simple diffussion
Explanation:
It is simple diffussion because it is the movement of gases or molecules of substance from a region of higher concentration to a region of lower concentration without using energy. Through this process gases are exchange between the alveoli of lungs and blood of the circulatory system. Carbon diffuses from tissues to lungs and oxygen diffuses from lungs to Tissues.
Answer:
diffusion
Explanation:

The diagram below represents part of a process that occurs in cells. Which process is represented?
The process in cells represented by the diagram would be translation or protein synthesis.
The translation is a process in cell biology during which the genetic codes in messenger RNA are decoded into their respective amino acids and linked together by peptide bonds. The process usually takes place in the ribosome of eukaryotic cells.
During translation, the genetic codes on mRNA are read and the amino acid corresponding to each code is released. The small ribosomal unit first binds to the mRNA at the beginning. Thereafter, the tRNA binds to the start codon on the mRNA before the binding of the large ribosomal subunit to complete the initiation complex.

Is starch a simple sugar molecule?
Answer:
yes because Most carbohydrates can be broken down by digestion into glucose and these are the carbohydrates
Explanation:
Answer:
Simple vs Complex Carbs. Carbohydrates are sugars that come in 2 main forms – simple and complex. This is also referred to as simple sugars and starches. The difference between a simple and complex carb is in how quickly it is digested and absorbed – as well as it's chemical structure

The plasma membrane is a thin flexible boundary between a cell and its enviorment.All cells have a plasma membrane. How does a plasma membrane maintain homeostasis within a cell
Answer:
The plasma membrane maintains homeostasis in the cell by keeping cell contents in and foreign material out, and by providing controlled routes for the transportation of fuel, fluids and waste.
The plasma membrane is very important because it allows a cell to maintain homeostasis by:
Controlling the flow of foreign substances into the cellControlling the movement of materials out of the cell Transporting materials within the cellHomeostasis refers to the inner environment of the cell being maintained such that it can carry out its duties.
The plasma membrane helps with that by first controlling what materials come into the cell to ensure that the inner environment isn't disrupted. It also limits those going out for the same reason.
Substances need to move around in the cell and the membrane handles this as well to ensure that substances get to the part of the cell where they help with maintaining the cell.
In conclusion, the plasma membrane is hugely important to the cell as it maintains homeostasis.
