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

The early ancestors of horses showed the presence of digits on their limbs, while modern horses have hooves. What are likely pos
klio [65]

The correct answers are evolution, genetic mutation and selection.

The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.

These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.

There are chances that evolution took place over a period of time that changed the character in the horse.

Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter
Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

In the electron transport system
antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.
