Answer:
Defective checkpoints results in death of the cell.
Normal checkpoints make sure the cell has enough resources for cell division. Normal checkpoints ensure the cells commits apoptosis if the cell has a problem it cannot fix itself.
How do enzymes affect the reactions in living cells?
Answer:
enzymes speed up the reaction
Explanation:
Enzymes increase the rate of biochemical reactions by reducing the amount of activation energy needed for reactants to start reacting.
Answer:
Activation energy decreases.
Explanation:
The way enzymes work is by lowering the activation energy required for reactions to take place within living cells.

Explanation:because it is stating that you have to see if there is anything involving chemical substances.
Beaker A contains 6 liters of water and 1 osmole of glucose. Beaker B contains 10 liters of water and 2 osmoles of glucose. Which one has the greater osmolarity and by how much?
From the ratio of glucose osmole to the volume of water in the two beakers, beaker B would have the greater osmolarity.
The term osmolarity refers to the number of particles of solutes or osmoles of substances per liter of solution.
In this case, the osmolarity of beaker A can be calculated as;
1 osmole/6 liter
= 0.167 osmolar
The osmolarity of beak B can be calculated as:
2 osmoles/10 liter
= 0.2 osmolar
Thus, beaker B with 0.2 osmolar has the greater osmolarity when compared to beaker A with 0.167 osmolar.
More on calculating concentrations can be found here: rainly.com/question/17329736
Answer: B
beaker A is 0.16 Osm/L and Beaker B is 0.2 Osm/L Beaker B has a greater osmolarity by 0.04 Osm/L

Place the following in the correct order as they occur in CELL RESPIRATION.
1. In cytosol, 6-C glucose and 2 ATP split into two 3-C molecules (glycolysis)
2. Acetyl Co-A enters mitochondria and drops off 2-C molecules
3. 2-C molecule combines with 4-C molecule and breaks into two 3-C molecules
4. Resulting 3 C molecule is stabilized BEFORE entering the mitochondria
5. Krebs cycle spins twice; each time stripping 1 carbon to make Co2 as a by-product
6. With each cycle of Krebs, electrons and H+ ions pop off, are picked up by NADH and FADH2 and taken to ETC

Explain the importance of gene regulation in prokaryotic cells.
-Explain the importance of gene regulation in eukaryotic cells.
Answer:
Prokaryotic cells can only regulate gene expression by controlling the amount of transcription. As eukaryotic cells evolved, the complexity of the control of gene expression increased. For example, with the evolution of eukaryotic cells came compartmentalization of important cellular components and cellular processes.

Note on chemical communication in insects in general
Answer:
Chemical communication plays an important part in the lives of insects, and particularly in lives of those that live in groups or social organizations. Aggregation pheromones are designed to bring individuals together into groups which may be temporary in sub-social insects, or permanent in social insects.
Explanation:
what is the difference between primary and secondary active trnsport
Answer:
In primary active transport, the energy is gotten directly from the breakdown of ATP. In the secondary active transport, the energy is gotten secondarily from energy that has been stored in the form of ionic concentration differences between the two sides of a membrane

Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.
Answer:
4.
Explanation:
Describe Wang’s solution for easily preventing the spread of disease on airplanes? What does “flow,” a word seen in the unit, have to do with his solution? The thing he made to prevent people from getting sneezes in their face is by making the bacteria flow straight towards the filters, so no one gets the bacteria in their faces.
Carbon dioxide is released as a byproduct of cellular respiration. Which one of these products is also formed during the metabolic reaction of cellular respiration? (B.9B)
Question 16 options:
Water
Glucose
Sucrose
Oxygen
The product that is also formed apart from the carbon dioxide during the cellular respiration process is water. The correct option is A.
What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, which is then used to drive ATP production.
Cellular respiration is the process by which cells in plants and animals convert sugar into energy, which is then used to perform cellular work.
The goal of cellular respiration is straightforward is that it provides cells with the energy they require to function.
Carbon dioxide and water are the byproducts of cellular respiration. Carbon dioxide is exhaled from your lungs after being transported from your mitochondria to your red blood cells. ATP is produced during the process.
Thus, the correct option is A.

1 - Brachialis, 2 - Brachioradialis, 3- Pronator teres, 4 - Palmaris Longus, 5 - Extensor carpi radialis, 6 - Extensor digitorum.
What is muscle?Muscle is defined as the group of the tissue and contraction has been defined as an action potential travels along the nerves to the muscle. The beginning of the muscle contraction which has been occurs with the signal generated from the nervous system.There are generally two types of the muscle contraction and the situation occur when the muscle contracts and the change in the size takes place.
Isotonic concentric contraction h been known as the type of muscle contraction in which muscle has been shortening takes place. Isotonic eccentric contraction has been the type of the muscle contraction in which the muscle lengthening whilst it is under tension.
