Answer:
The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.
Explanation:
Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins.
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

What would happen inside a cell if it's lysosomes had leaky membranes
Answer:
Explanation:The membrane "sacks" would have to be broken open in order for the enzymes to reach the interior of the cell.
Answer:
If the lysosomes had a leakage, then it could cause plasma membrane disruption.
enzymes are important because they contain what?
Answer:
Enzymes are proteins that serve as catalysts for certain chemical reactions. They help the human body properly digest food and break down molecules into smaller units so that the intestines can absorb all its nutrients. Enzymes occur naturally in several foods and eating them raw gives the body an ample supply to help properly digest food, maintain optimum condition of the internal organs, as well as fight cancer cells
Explanation:
Enzymes is on
Sprouts
Nuts and Seeds
Fruits and Vegetables
Papaya and Pineapple
Which one of the following components is responsible for the clotting of blood? Select one: O a plasma O b. leukocytes O c. hemoglobin O d. thrombocytes
Answer:
D. thrombocytes
Explanation:
The main function of thrombocytes is to stop the bleeding of injured blood vessels. In mammals, thrombocytes are anucleated cell fragments called platelets.
Thrombocytes is responsible for the clotting of blood.
What are thrombocytes?
The microscopic blood cells known as platelets, or thrombocytes, aid in blood coagulation. Your body naturally stops bleeding with platelets.
Plasma, red, white, and platelet-containing blood cells make up whole blood. Platelets, the lightest component of whole blood, are pushed to the walls of your blood vessels because they are the heaviest part of the blood.
This allows plasma and blood cells to flow through the center, allowing platelets to reach injury rapidly to stop bleeding.
Therefore, Thrombocytes is responsible for the clotting of blood.

What is never found inside the lipid bilateral of a cell membrane
Answer:
Cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.
Explanation:
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly. Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids. The passage of these molecules relies on specific transport proteins embedded in the membrane.

Which letter in the image above represents the activation energy of a reaction
WITHOUT an enzyme present?
C
B
A & B
A
Answer: B
Explanation: Because the Red shows activity
Activation energy is defined as the minimum amount of energy required for activating the atoms or molecules to undergo chemical transportation or transfer.
The correct answer is:
Option D. The letter A.
In the graph, activation energy can be explained as:
1. The activation energy is the minimal amount of energy necessary for the compounds to participate in the chemical reaction.
2. In the graph, the activation energy without the enzyme is represented by A, the activation of energy with enzyme is represented by B, and the change in the free energy is represented by C.
Thus, the correct answer is Option D.

C) Cool air is warming quickly.
D) Warm air is above land.
Answer:
The answer is C
Explanation:
Answer:

Explanation:
what happens to the 90% of energy available if 10% moves on to the next trophic level
Answer:
Released as heat
Explanation:
The vast majority of energy in the ecosystem is used by the organisms to power chemical reactions in the cell.
Therefore, this energy is lost as heat when it powers metabolic processes, rather than being passed on to the next trophic level.
how does coriolis effect affect the climate zones in the world? PLEASE HELP! I WILL GIVE BRAINLY TO PROPER ANSWER!
Answer:
Please Mark as Brainliest
Explanation:
The development of weather patterns, such as cyclones and trade winds, are examples of the impact of the Coriolis effect. ... As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) as they move northward.

What is the theory of natural selection, and why does it occur in an organism?
Answer:
Natural Selection is survival of the fittest aka Darwinism. It basically states that the strongest survive and the weakest don't. Maybe it's through food shortages, bad weather, or predators. It occurs in an organism for population control. If there is too big of a population, then there will be a recourse drought and natural selection will do its thing again.

A toy car accelerates 1.25 m/s2 when a child pushes it with a force of 0.1 newtons. What is the mass of
the car?
Answer:
0.089
Explanation:
The formula to solve for mass is:
m=F/a
So, The force is 0.1, and the acceleration is 1.25^2.
First you must square 1.25, which will give you 1.12 ( I rounded).
Now, we have 0.1/1.12, which equals 0.089, or 0.09.

explain what natural selection is and how it occurs
Answer:
Natural selection is when an animal adapts to their environment to survive and produces more offspring. It occurs when the animal isn’t thriving in their environment and they make adaptions to where they can survive.

How might other organisms in the ecosystem be affected? What might happen to the population sizes of various types of organisms in the Everglades?
Answer:
As the Burmese python surpasses its carrying capacity in South Florida, the overpopulation of it leaves less resources for each python, and other organisms. Predators may have way too many pythons, and not be able to keep the balance, and prey might be over hunted or eaten. The population sizes may decrease due to the over-population of the pythons.
Explanation:
If there are ever too many of any ORGANISM in a ecosystem, the balance is sure to be ruined.
