The teacher was unaware of the difference between suspension feeding and predation. The teacher thought that providing live copepods (2 mm long) and feeder fish (2 cm long) would satisfy the dietary needs of all of the organisms. Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)
Answer:
The correct answer is - Biwalves and sponges.
Explanation:
Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.
Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.
The correct answer is - Biwalves and sponges.
Starting with pyruvate to make acetyl-CoA and continuing into the citric acid cycle, and oxidative phosphorylation, how many ATP can be made from 1 molecule of pyruvate
Answer:
The correct answer is - 15 ATPs.
Explanation:
Cellular respiration (aerobic) is the process that involves glycolysis, oxidative decarboxylation, citric acid cycle and oxidative phosphorylation or ETS to breakdown one molecule of glucose in order to generate energy in ATPs. Pyrivate is the end product of glycolysis and it is go to form acetyl CoA.
One molecule of pyruvate genrates 1 molecule of FADH2, four molecules of NADH, and 1 molecule of ATP during oxidative decarboxylation and citric acd cycle. During the oxidation in the electron transport system there is 4 molecules of NADH2, 1 molecule of FADH2, and 12 (4×3) ATP molecules, respectively by oxidation in the electron transport system (ETS).
Thus, there would be 15 molecules of ATPs produce by one molecule of pyruvate.

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.
Answer:
Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.
Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.
Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.
Which statement is FALSE?Question 39 options: Water can hold an unlimited amount of oxygen. Water can hold less oxygen than air can. Underwater organisms need oxygen. A small decrease in dissolved oxygen can have an effect on aquatic life. Underwater organisms use oxygen in cellular respiration.
Answer: Water can hold an unlimited amount of oxygen.
Explanation:
Water cannot hold an unlimited amount of oxygen because it would get to a point where it is saturated as it needs to hold Hydrogen as well. Air on the other hand, has significantly more space for oxygen as it contains only 21% and can keep taking more.
Underwater organisms need oxygen for respiration and a small decrease in the oxygen available in water affects aquatic life because they rely on it to survive.
Cross-contamination of food occurs when a. perishable foods are kept at room temperature for more than 2 hours b. a utensil contaminated with a microorganism from a previously handled food contacts a second food c. two or more food handlers work on the same food d. two or more microorganisms grow in the same food
ANSWER: B
explanation: from what I learned in culinary arts, this is kind of a trick question. Its not asking how foods can get contaminated, its asking how CROSS CONTAMINATION can occur. Cross contamination occurs in three ways think of it like this: food-to-food, equipment-to-food, and people-to-food. The answer has to be between B and C. But the answer is B, because the utensil is already contaminated and it is coming in contact with another food. The two or more food handlers working on the same food are not bringing anything contaminated into the situation. Unless they are contaminated (by they I mean their hands lol) then it cross contaminates but that's not it lol im 99% sure the answer Is B.
Cross-contamination of food occurs when two or more foods come into contact with each other, transferring microorganisms from one food to another. This can happen in a number of ways, including direct contact, contact with a contaminated surface or utensil, contact with a contaminated food handler, or contact with airborne microorganisms.
What is the most common type of cross-contamination ?The most common type of cross-contamination is direct contact, which can occur when one food touches another. This is especially true of perishable foods, which should not be kept at room temperature for more than two hours.
If they are kept at room temperature longer than this, bacteria and other microorganisms can quickly multiply, potentially leading to cross-contamination.
Another common way for cross-contamination to occur is through contact with a contaminated surface or utensil. If a utensil that has been used to handle a food contaminated with microorganisms comes into contact with a second food, the microorganisms can transfer to the second food and cause cross-contamination.
Similarly, if two or more food handlers work on the same food, their hands can transfer microorganisms from one food to another, leading to cross-contamination. Finally, if two or more microorganisms grow in the same food, they can interact with each other and potentially cause cross-contamination.

Answer:
Husky. Why not?
Explanation:
Modern plant-breeding techniques (artificial selection in action) have reduced genetic variability in many of our most commercially valuable plants. To most people, that would generate a shrug. However, a biology student that has studied evolution understands the problem with this. Briefly explain why there is an issue with this.
Answer:
There is an issue with the artificial selection.
Explanation:
There is an issue with this artificial selection because the genetic variability is reduced when we do again and again the artificial selection. In the artificial selection, the selected genes are combined with the one another and does not allow natural fusion or combination of genes that is responsible for the genetic variability in the organisms so that's why we can say that this artificial selection is an issue that reduce genetic variability.

Explanation:
You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)
Answer:
Nuclear lamins will no longer disassemble during mitosis
Explanation:
The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.
