Answer:

prokaryotes

Explanation:

Prokaryotes were the first living beings to appear on earth, about 3 billion years ago. By evolution, prokaryotic cells gave rise to eukaryotes.

At the beginning of our planet, the first forms of life should have a very simple cellular organization. This is because the planet still had inhospitable characteristics that would be unable to support more complex life forms. In this scenario, prokaryotes would be the organisms most likely to survive and thanks to their existence, the most complex forms of life were able to exist.

Match each product of pyruvate metabolism with the condition under which it is produced. Drag each item to the appropriate bin.
bekas [8.4K]

Answer:

Lactate: fermentation in human muscle

Ethanol: fermentation in yeast and bacteria

Acetyl CoA: aerobic oxidation

Explanation:

Lactate is produced in lactic fermentation in human muscle. Lactic fermentation in muscle cells is a process that occurs alternatively, in situations where the body does not perform aerobic respiration. Considered a short-term metabolic device, activated when the body is subjected to intense physical effort under conditions of low muscular oxygenation.

Alcoholic Fermentation, also known as ethanol fermentation, is the anaerobic pathway performed by yeast and some bacteria, in which simple sugars are converted to ethanol and carbon dioxide. Yeasts usually function under aerobic conditions, either in the presence of oxygen, but are also capable of functioning under anaerobic conditions, or in the absence of oxygen. When oxygen is not readily available, fermentation alcoholic beverages occur in the yeast cell cytoplasm.

Acetyl CoA results from aerobic oxidation. This process occurs in mitochondria during cellular respiration, where pyruvate, the product of glycolysis, can be substituted, and often is, by fatty acids. This is because pyruvic acid is used to form a compound called Acetyl Coenzyme A or Acetyl CoA. In this sense, Acetyl CoA can also be produced by the degradation of fatty acids by a reaction called β oxidation.

Describe telephase (IN YOUR OWN WORDS)<br> -Thank you!
Luba_88 [7]

Answer:

Telophase is the last step of cell division, when chromosomes move in opposite directions so two new cells can be formed from one. When a cell is finishing the process of meiosis, it goes through a phase in which it's basically getting ready to split into two new cells telophase.

Airida [17]

Answer:

1. mushroom

2. nucleus

3. eukarya

4. animalia

5. button mushroom

Explanation:

1. Mushroom because everything else in the list is an animal, while a mushroom is a fungi.

2. Nucleus because eukaryotic and prokaryotic are types of formations of a cell, while a nucleus is part of a cell and not a cell formation.

3. Eukarya because the Eukarya include all animals, plants, fungi, and protists. These organisms are eukaryotes, meaning they have membrane-enclosed nuclei within their cells. The Bacteria and Archaea are both considered prokaryotes, because their cells lack true nuclei, meaning a membrane does not enclose their genetic material.

4. Animalia because fungi and plantae are stationary organisms, while animalia are mobile. (ex. fungi and plantae= roots and animalia= feet/ not attached to one place)

5. Button mushroom because sunflowers and oak trees are producers, while a button mushroom is a decomposer.
