How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohy
jeyben [28]

Answer:

Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.

Explanation:

A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.

What condition is required for fermentation to occur? A. When oxygen levels within a cell are too low for aerobic respiration B.
Leokris [45]

Answer:

A. When oxygen levels within a cell are too low for aerobic respiration

Explanation:

Fermentation is a chemical or metabolic process that occurs in organism, when a carbohydrate such as glucose is metabolized or converted to an alcohol anaerobically (absence of oxygen).

When an organism lacks oxygen within the cell, aerobic respiration would be halted, hence pyruvate produced from glucose further undergoes fermentation anaerobically.

Organisms like lactic acid bacteria and yeast carry out fermentation. The process of fermentation is widely used in food industries, such as in brewing of wine or manufacture of yogurt.

What is biology terms​
Nady [450]

Answer:

Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[

A specific example of a light year is used in space exploration
Pani-rosa [81]
Light-year or lightyear (symbol: ly) is a unit of measurement of length, specifically the distance light travels in a vacuum in one year.

While there is no authoritative decision on which year is used, the International Astronomical Union (IAU) recommends the Julian year.

A light-year is equal to 9,460,730,472,580.8 km (about 9.461 Pm; 5,878,625,373,183.61 statute miles; about 63,240 astronomical units or about 0.3066 parsecs.

The exact length of the light-year depends on the length of the reference year used in the calculation, and there is no wide consensus on the reference to be used.

The figures above are based on a reference year of exactly 365.25 days (each of exactly 86,400 SI seconds).

A few examples of distances for light to travel are: Reflected sunlight from the Moon's surface takes 1.3 seconds to travel the 4.04 × 10-8 light years to Earth.

It takes 8.3 minutes for light to travel from the Sun to the Earth (a distance of 1.58 × 10-5 light-years).

The most distant space probe, Voyager 1, was 13 light hours (only 1.5 × 10-3 light years) away from Earth in September 2004.

It took Voyager 27 years to cover that distance.

The nearest known star (other than the Sun), Proxima Centauri is 4.22 light years away.

The center of our galaxy, the Milky Way, is about 26,000 light years away.
