Which plant division has seeds with a 3n endosperm due to double fertilization?
matrenka [14]

Answer:

Angiosperms have seeds with an 3n endosperm due to double fertilization.

Explanation:

  • Double fertilization is found only in flowering plants.
  • In angiosperms, the female gametophyte does not grow after reaching eight nucleate stage.
  • After fertilization and triple fusion, the zygote and primary endosperm are created and further growth of embryo sac continues.
  • Triple fusion is the fusion of two haploid polar nuclei of female gametophyte and one male nuclei. This results in a  3n nucleus.
  • The developing embryo obtains nutrition from the endosperm.
  • If fertilization fails no endosperm is formed.

What are the three main processes that make up aerobic respiration? Name each process, provide a brief description of the proces
IRISSAK [1]

Answer:  

Aerobic respiration is a process glucose produces energy in the presence of oxygen. In this process glucose is oxidized to produce carbon dioxide, water and energy in the form of ATP.

C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + Energy (ATP)

Three main processes that make up aerobic respiration are:

1. Glycolysis:  it takes place in the cytosol of the cell. Here, glucose is oxidized to form three carbon molecule pyruvate. This process produces energy in the form of 2 ATP molecules and 2 NADH molecules. These NADH molecules carries 2 energy electrons these electrons are utilized by the electron transport chain.

2. Kreb's cycle: it takes place in the cytoplasm and mitochondria of the cell. Here, the molecules of pyruvate produced during glycolysis is utilized to produce ATP.

3. Electron transport chain:  glucose is not entirely converted into ATP. The NADH molecules produce during glycolysis  produces 2 energy electrons these electrons are taken up by electron transport chain in the mitochondria inner matrix. A proton gradient develops across the matrix after donation of electrons to electron transport chain. This gradient in turn produces energy in the form of ATP.

A roasted chicken multigrain sandwich contains 42 g protein, 7 g fat, and 34 g carbohydrates. How much energy does the sandwich
Andrei [34K]

1 -

Calories per gram of:

Fat = 9

Charbohydrates ≈ 4

Proteins ≈ 4

So, now we do the math:

34g of charbohydrates equals 34*4g of calories, therefore, 136.

7g of fat equals 7*9g of calories, therefore, 63.

42g of protein equals 42*4g of calories, therefore, 168

136 + 168 + 63 = 367 grams

Answer:

367 grams of calories in the chicken multigrain sandwhich.

During photosynthesis, protons build up in the thylakoid lumen/space. The left-overs of this building-up are then conduced to the stroma where they generate ATP.

Answer:

Thylakoid lumen.

Image 2 -

Just with the salmon fillet, he has already eaten enough vitamin B12, more than 100% of the recommended daily allowance. The amount of vitamin E of the salmon fillet was low, and the amount of vitamin C was null.

The boiled green beans gave him quite a lot of the vitamin C he needs, but not enough. The vitamin E that the boiled green beens provided was also not enough. The amount of vitamin B12 was null.

The sliced strawberries where enough to back up the lack of vitamin C of the boiled green beans, but not enough to back up the lack of vitamin E. The amount of vitamin B12 was null.

Math:

If we do the math needed, we see that Robert only had enough vitamin B12 and C, and that he needed way more vitamin E.

Answer:

B. - Vitamin B12 and C only.
