A hungry yeast cell lands in a vat of grape juice and begins to feast on the sugars there, producing carbon dioxide and ethanol

in the process:
C6H12O6 + 2ADP + 2Pi + H+ → 2CO2 + 2CH3CH2OH + 2ATP + 2H2O

Unfortunately, the grape juice is contaminated with proteases that attack some of the transport proteins in the yeast cell membrane, and the yeast cell dies. Which of the following is the most likely cause of the yeast cell’s demise?

a. toxic buildup of carbon dioxide inside the cell
b. toxic buildup of ethanol inside the cell
c. diffusion of ATP out of the cell
d. inability to import sugar into the cell
e. inability to take water into the cell

a laptop power changer has an output of 5.00 V ang has a resistance of 800 ohms. what is the current output of the charger?​
DochEvi [55]

Answer:

The correct answer is - 6.25 mAh.

Explanation:

According to the Ohms law of power, the current of a source can be found with the help of the formula

I = V ÷ R

where, I (amps) = V (volts) ÷ R (Ω)

By placing the value given:

I = 5.00/800

I = 6.25 mAh

The current output of the charger would be 6.25 mAh

The term ""biomagnification"" means that a chemical ____ at each trophic level in a food chain or web.
Tasya [4]

Answer:

Increases

Explanation:

Biomagnification refers to a phenomenon in which the harmful toxic chemical gest magnified or amplified or increases in the food chain trophic level.

The biomagnification is caused by the bio-accumulation of the toxic material in the organisms.

The harmful toxic chemical enters the food chain through eating like when the crops are sprayed with pesticides and insecticides runoff in the water. From there the toxic material enters the aquatic food chain like from the planktons to fish and then to vultures.

The organisms at higher trophic level die because of the accumulation of the infected lower trophic organisms.

Thus, Increases is the correct answer.

11) In C3 photosynthesis, the reactions that require ATP take place in A) the light reactions alone. B) the Calvin cycle alone.
valentinak56 [21]

Answer:

In C3 photosynthesis, the reactions that require ATP take place in

B) the Calvin cycle alone.

Explanation:

In C3 PLANTS PHOTOSYNTHESIS OCCUR IN TWO STEPS-

1. LIGHT stage , WHICH TAKES PLACE IN LIGHT. In this stage water is split and ATP is released.

2. DARK stage, which takes place in dark. This the stage where calvin cycle takes place which require ATP, i.e energy. In this process sugar is produced with help of carbon dioxide. In this carbon dioxide is accepted by 5- carbon molecule ribulose-1, 5-biphosphate, which result into two molecules of 3- phosphoglycerate. this three carbon compound. hence is called as C3 pathway. hence C3 plants.
