HOW DO YEAST RESPIRE?
Yeast are unicellular organisms that belong to the kingdom Fungi. Yeasts are capable of respiring anaerobically i.e. can respire without oxygen. Yeast can, however, respire both aerobically and anaerobically. Yeast undergoes an anaerobic respiration called FERMENTATION, which is used to produce ethanol (alcohol) from pyruvate (product of glycolysis). If a substance that inhibits the conversion of pyruvate to ethanol is added to yeast cells growing in a petri dish, the process of fermentation will be inhibited. Hence, the yeast cells will have to switch to aerobic respiration and make use of oxygen.Therefore, adding the inhibitor to the yeast cells in the petri dish would likely cause an increase oxygen usage by the cell.

Which plants are most likely to adapt successfully to a climate change in their environment?
O A) plants that grow rapidly
O B) plants that reproduce asexually
O C) plants that are cross-pollinated
OD) plants that do not rely on wind-pollination
Answers
Answer:
A
Explanation:
plants that grow rapidly
The plants that are most likely to adapt successfully to a climate change in their environment are ; ( B ) plants that reproduce asexually
The change in climate favors some plant species while negatively affecting other plant species. most plants depend on the climate/weather like the wind for its reproduction/survival.
Most plants are cross-pollinated while some are wind pollinated therefore they will require the right weather/wind conditions to adapt and survive in their environment, plants growing rapidly can be hindered by changes in climate conditions.
But plants that reproduce asexually do not rely on the climate conditions to carry out their reproductive activities which makes them the most likely to adapt successfully to a climate change in their environment.
Hence we conclude that The plants that are most likely to adapt successfully to a climate change in their environment are plants that reproduce asexually

A farmer wanted to control wind erosion across a 1200 foot field. The wind blows predominately in that direction (i.e., across the 1200 foot field). She decided to plant a windbreak that would be 20 ft tall at maturity. How many windbreaks should she plant, assuming that the windbreaks are perpendicular to the predominate wind direction? Recall from the Lecture 7 slides that the downwind area protected by a tree is 20 times greater than the height of the tree.
Group of answer choices

3
Answers
Answer:
Explanation:
The downwind area protected by a tree is 20 times greater than the height of the tree. Therefore, a windbreak that is 20 ft tall at maturity would protect an area of 20 x 20 = 400 ft downwind.
To cover a 1200 ft field, the farmer would need to divide it into sections of 400 ft and plant a windbreak at the end of each section. This would require a total of 1200/400 = 3 windbreaks.
Therefore, the farmer should plant 3 windbreaks to control wind erosion across her 1200 foot field. The answer is option D.

Answers
Answer:
Explanation:
If cytokinesis did not occur, the cell cytoplasm will not be able to undergo division or divide. As a result, there won't be division of two daughter cells that are identical to the parent. Therefore, it will remain at rest and there won't be separation or division of the parent cell. The cell will still remain as it was. Therefore, there won't be cell division.

Answer:
no difference
Explanation:
There is no difference between plant and animal glycolysis. Glycolysis is an important step of respiration and refers to the break down of glucose molecule for the generation of energy in the form of ATP. Both plant and animal glycolysis occurs in the cytoplasm of the cell where glucose molecule is broken down and produces 2 molecules of pyruvate and 2 molecule of ATP. This process occurs without the use of oxygen molecule.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
Answers
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.

Sea anemones are predatory invertebrates with stinging tentacles that can paralyze many sea animals. The clownfish is immune to the sting of the sea anemone and actually lives among its tentacles. The relationship is mutually beneficial—the clownfish often lures meat-eating animals over to the anemone, and the anemone benefits from the meal. The clownfish often gets to eat leftovers from the anemone’s meal.
When the clown fish is ready to lay eggs, it lays them near a sea anemone. How’s this a reproductive strategy?
Answers
The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.
By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.
In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.
The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.
The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.
