The Venn diagram compares aerobic respiration and anaerobic respiration.
Which statement should be categorized only in the aerobic section of the Venn diagram?
occurs in the cytoplasm
produces water
requires no oxygen
is performed by yeast
The statement should be categorized only in the aerobic section of the Venn diagram - produces water.
Aerobic respiration is the process that occurs in the presence of oxygen. In this oxygen breaks down the amino acids, fatty acids, and glucose to generate ATP in the body.
Aerobic respiration does not occur in the cytoplasm but in mitochondria.Aerobic respiration produces water and carbon dioxide as the end product.Aerobic respiration itself is a process that takes place in the presence of oxygen.Aerobic respiration is performed by mitochondria and not yeast. In yeast fermentation takes place.carbon in glucose is oxidized to produce carbon dioxide whereas oxygen is reduced to form water.H₂ + 1/2 O₂ →H₂O
Thus, the correct choice would be - produce water.

What is the primary mode of transmission of microorganisms to food and food contact surfaces?
This is a process by which substances are transported across cell membranes by means of protein carrier molecules.
Answer:
Facilitate diffusion is the process in which substances are transported across the plasma membrane along the concentration gradient with the help of carrier molecules.
In active transport also carrier proteins are used but they are used to transport the molecules against the concentration gradient.
Carrier proteins bind the molecules to be transported non-covalently and after binding, it undergoes a conformational change which helps in the movement of the molecule through the protein inside the cytoplasm of the cell.
Charged and polar molecules are mainly passed through facilitated diffusion like amino acids, carbohydrates, ions. The rate of transfer of molecules across the plasma membrane is higher in facilitated diffusion than simple diffusion.
Which of the following is most responsible for El Niño?: a. Unusually cold water in the Atlantic causes an increase in wind activity. b.

Based on your understanding of the terms proximal and distal, the distal sesamoid bone in the equine leg would be expected to have which relationship to the proximal sesamoid bone found on the same leg?
Answer:
The distal sesamoid bone is closer to the hoof than the proximal sesamoid bone.
Explanation:
A part is said to be at a proximal position if it lies closer to the point of attachment in the body. If a part is situated at a position away from the point of attachment of the body then it is said to be at a distal position. Equine is a horse, in the equine leg, the point of attachment begins to form the scapula and then the legends in the hoof.From the term proximal and distal it is clear that the proximal sesamoid bone will be closer to the scapula and the distal will be closer to the hoof of the leg.What kind of lipid forms when a glycerol combines with fatty acids through dehydration synthesis?

Which of the following true statements best supports the endosymbiotic theory? Select one: a. All mitochondria have circular DNA. b. All eukaryotic cells have ribosomes. c. All eukaryotic cells have DNA. d. All mitochondria function as powerhouses to the cell.
Answer: c. All eukaryotic cells have DNA
Explanation: The endosymbotic theory deals on the mitochondria and chloroplasts to having their own DNA and this DNA maybe similar to bacterial DNA. This theory was later proven to be true for DNA, RNA, ribosomes, chlorophyll and protein synthesis.
The statement 'All mitochondria have circular DNA' best supports the Endosymbiotic Theory as it is evidence that suggests mitochondria were once independent prokaryotic organisms.
Explanation:The Endosymbiotic Theory is the scientific theory that explains how eukaryotic cells (cells with nuclei and other internal organelles) evolved from prokaryotic cells (cells without a defined nucleus). Among the answer choices provided, the statement that best supports the Endosymbiotic Theory is that 'All mitochondria have circular DNA' option a. The reasoning behind this is that circular DNA is a characteristic of prokaryotes, and thus, the presence of circular DNA in mitochondria (a sub-cellular organelle in eukaryotes) supports the theory that mitochondria were once independent prokaryotic organisms that became incorporated into eukaryotes through Endosymbiosis.
