lactic acid
Lactic acid
pyruvate
mitochondria

For ethanol fermentation, the correct options are:

pyruvate
CO₂

<h3>What is a anaerobic respiration?</h3>

Anaerobic respiration is respiration which occurs in the absence of oxygen.

Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.

Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.

In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.

On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.

After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.

In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.

Clostridium Difficile (C. difficile) is a type of bacteria that increases its activity with most antibiotic use, and is therefor

storchak [24]

Answer:

The government should not go ahead with this plan.

Explanation:

If the government decides to proceed with its plan to pass a law that authorizes the management of a hospital to force people who refuse to wash their hands out of a hospital and deny them medical care against their will, then the government will be infringing on people's right to life. While it is necessary to prevent the spread of Clostridium Difficile (C. difficile) , any law that is made to that effect must not abuse the right of access to medical care which is a fundamental right of citizens. This action will be ethically incorrect because it amounts to a government using a high handed approach in discharging its duties.

However, the intention of such a law is to protect the citizenry from the bacteria Clostridium Difficile (C. difficile) . If such a law is not passed, more people may become infected by the bacteria owing to the carelessness of other people. This situation is made worse because the organism is resistant to antibiotics.

However, since prevention of the spread of Clostridium Difficile (C. difficile) is Paramount, I opine that the government should continue to enlighten citizens and appeal to them on the need to practice regular hand washing in order to protect themselves and other people. Passing the said law is a draconian approach to the problem hence it is not in line with the ethics of modern civilization.

It is more civil to continue to appeal to citizens and sensitize them on the importance of regular hand washing as it affects the spread of Clostridium Difficile (C. difficile) .

Punnet square worksheet!<br><br> help please.

NemiM [27]

Answer:

long are W which means that they are stronger than the w trait of short.

1)the big word means that it will have two W traits, (or W,W), and heterozygous will mean that the seal will have one W and one w, (or W, w).

your Punnett Square will look like this W W which means that 100% of

these W W W W W

seals w W w W w

will have long.

2)Heterozygous and a short will look like this

w W w w w

w w w w w

which means that only 25% will have long and 75% will have short, this is due to how W traits will almost always beat recessive traits.

3)Now one is, (H) and two is, (h). Two Hybrid means that they are Heterozygous. This will make your Punnett Square look like this

H h

H H H H h

h H h h h

the possible Genotypes willbe H H, H h, h h.

Phenotypes, looktraits willbe One,and Two.

The dialysis tube was permeable to which substance? how did you determine this?

Dafna11 [192]

Answer:

It was concluded that the dialysis tubing doesn't allow all kinds of substances to pass readily through the pores of its membrane. This means that it is selective in its permeability to substances. The dialysis tubing was permeable to glucose and iodine but not to starch.
