The mass of an electron is
vodka [1.7K]

Answer:

not significant to the overall mass of the atom

Explanation:

The mass number of an atom is the combination of the mass of the protons and neutrons.  Electrons are not included because their mass are so insignificant that is doesn't change the total mass much, therefore they are left out. The mass of an electron is about 1,830 times smaller than protons and neutrons.

During which process is ethanol produced?
Kipish [7]

Answer:

Alcohol fermentation

Explanation:

When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration

One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.

Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture

This process is taken advantage of to brew beer and wine.

Sex linked inheritance usually occurs on the X chromosome. Males have one X, meaning if they receive the specific sex linked gene, they will have the trait. However for a female to possess the trait, she must receive 2 X chromosomes for that trait.

What must happen before meiosis can begin
RUDIKE [14]

Answer:

The correct answer is option C.

Explanation:

Before meiosis, DNA that is stacked into chromosomes must replicate. Before replication, the sex cell has two copies of each chromosome, one from mother, and one from father.

DNA replication takes place in the same manner as it does during mitosis. After the chromosome replication, the homologs are double in number, and each chromosome now has a homologous pair of chromosomes.

Thus, the correct answer is option C.
