Living organisms evolved in a world where they were constrained by the laws of physics and chemistry. Describe the two laws of t

hermodynamics and explain how each law impacts the structure of an ecosystem's food chain as energy flows from one trophic (feeding) level to the next

Answer:

The laws of thermodynamics are important unifying principles of biology. These principles govern the chemical processes (metabolism) in all biological organisms. The First Law of Thermodynamics, also known as the law of conservation of energy, states that energy can neither be created nor destroyed. It may change from one form to another, but the energy in a closed system remains constant.

2. Describe the trans-<br>formation of energy<br>that occurs during<br>photosynthesis.<br>​
Viefleur [7K]

Answer:

Explanation:

Photosynthesis is the process plants use to convert energy from the sun into usable energy for their cells. Plants use the light energy of the sun, carbon dioxide, and water to make glucose (a sugar), and oxygen. The energy of the sun is captured and stored in the bonds between atoms in glucose molecules.

Why are G protein only found in Eukaryote cell ?
Levart [38]

Answer:

they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes

Explanation:

G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

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.

First let's see what does indigestible mean:

Indigestible means that the body does not digest that substance, it is eaten, and released. No modification happens to it.

Which of the components below are indigestible:

The only indigestible food component mentioned in exercise 2 is fiber. Fiber, which provides from plants, is not digestibe by the body.

Answer:

Fiber.

This is not my area of expertise, but I must say, it's kind of obvious that the deficiency the patient suffers is vitamin C deficiency.

In a vitamin C deficiency, patients suffer from things such as the ones mentioned in the question.

Answer:

Vitamin C.

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.

Hope it helped,
