Which statements accurately describe fermentation? Select two options.
Oxygen is present during this process.
Cells may convert pyruvic acid to lactic acid.
NAD+ is converted to NADH.
Fermentation is an anaerobic process.
Additional ATP is produced after glycolysis.
Answer:
The answers are the second and fourth ones.
Explanation:
I did the assignment.
The statements that accurately describe fermentation are cells may convert pyruvic acid to lactic acid, and fermentation is an anaerobic process. The correct options are B and D.
What is fermentation?Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the bubbling that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.
It is different from aerobic respiration because it occurs in the absence of oxygen and aerobic respiration occurs in the presence of oxygen. The product of fermentation is lactic acid, which is produced from pyruvic acid.
Thus, the correct options are: B, Cells may convert pyruvic acid to lactic acid, and D, Fermentation is an anaerobic process.

taj incorrectly states that autographs are also known as consumers that need to feed on other organisms, including plants and animals, to gain energy. which of the following best describes consumers that feed on other organisms such as plants and animals for energy?
A. carnivores
B. trophic levels
C. heterotrophs
D. herbivores
Herbivores best describes consumers that feed on other organisms such as plants and animals for energy.
What do you mean by herbivores?A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.
Many herbivores have large, dull, flat teeth. These teeth are excellent for chewing and breaking down tough plant material. Carnivores have sharp, narrow teeth that are better for biting and tearing flesh. However, some herbivores also have strong, sharp teeth.
Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses.

There are many different types of cells with many different types of cellular structures and functions. Which of these structures is found in all types of eukaryotic cells?
A. chloroplast
B. cell wall
C. nucleus
D. centrioles
Answer:
nucleus
Explanation:
chloroplasts and cell walls are only found in plant (and fungi) cells, while centrioles are only in animal cells.
The structure that is found in all types of eukaryotic cells is the nucleus. The correct option is C.
What are eukaryotic cells?Eukaryotic cells are those cells that contain true cell organelle. These cells are present in the higher organism, and they perform complex functions like replication, mitosis, etc.
There are two types of cells. They are prokaryotic and eukaryotic cells. Prokaryotic cells are those that do not contain an organelle and a nucleus. They are present in smaller organisms.
The nucleus is the brain of cells. It controls all functions of cells, and it contains the genetic material of the organisms. In prokaryotic cells, the nucleus is absent and in eukaryotic cells, the nucleus is present. That is the difference between them.
Thus, the correct option is C. nucleus.

Which plant propagation process insures some genetic diversity?
Answer:
Seed propagation takes place during sexual reproduction. The production of seeds through auto-pollination or crossed pollination ensures some genetic variation.
Explanation:
Seeds ensure the existence of genetic variation between plants. There are two general crossing systems in plants, which depend on pollination type.
Self-pollination occurs when the flower pollen is transferred to the same flower stigma, reaching that individual egg to fertilize it. These are autogamous systems. Crossed pollination occurs when the mature pollen is driven by different pollinator agents from one flower to another, reaching the other flower stigma and fertilizing its eggs. These are xenogamous systems.Sexual reproduction gives more possibilities to different alleles of a gene that did not appear in one generation to express in the next generation. Both types of pollination allow genetic variation, however by the occurrence of crossed pollination there are more chances to ensure the variability of the species and survival to environmental changes. While by self-pollination there are more chances to express the same genotype of the parental plant. The Xenogamous system has the advantage of avoiding the effects of endogamy in a population.

Every cell contains DNA. The main purpose of DNA is to store the cell’s genetic information. How does DNA control the cell?
A. DNA activates nerve signals in the nervous system
B. DNA speeds up chemical reactions and lowers activation energy
C. DNA protects the cell from invaders.
D. DNA determines what proteins are made.
Answer:
The answer is D: DNA determines what proteins are made.
Explanation:
The nucleotide sequences that make up DNA are a “code” for the cell to make hundreds of different types of proteins; it is these proteins that function to control and regulate cell growth, division, communication with other cells and most other cellular functions.This process is called protein synthesis.All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
Hope this helps!! ;)
DNA controls the cell by determining what protein are synthesized by the cell. Thus, the correct option is D.
What is Translation?Translation is the process of synthesis of proteins from the mRNA (messenger RNA) of the cell. This process occurs in the ribosome of the cell. In this process, the mRNA produced from the DNA encodes amino acids which join together to form large polypeptide and protein molecules.
mRNA are produced from DNA through the process of transcription. Transcription occurs in the nucleus of the cell. Through this process, DNA produces a sequence of mRNA which is complementary to it. This mRNA determines what proteins will be synthesized by the cell.
Therefore, the correct option is D.

Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP
A. Transport from complex I produces more ATP.
B. Transport from complex II produces more ATP.
C. Both produce the same amount of ATP.
Answer:
A
Explanation:
ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.
Electron transport from complex I produces more ATP.
ELECTRON TRANSPORT CHAIN:
The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration. The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis. The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers. Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space. Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.Learn more: https://brainly.com/question/442662?referrer=searchResults
