Answer:

The correct answer is 10% and 90% respectively.

Explanation:

The transfer of the energy in the ecosystem is only 10% of the energy and the rest 90% energy lost as the heat through each trophic level of the ecosystem. The producers get their energy from the sun in the form of solar energy. Producers like Grass and other plants absorb 10% of the solar energy they get and rest lost as heat.

This loss of energy as heat also occurs at every trophic level. From the producers to different levels of consumers to decomposers. The energy can not be destroyed or created it just changes its form.

Thus, the correct answer would be 10% and 90% respectively.

Bile

Based on the above symptoms, it can be inferred that Gloria lacks bile. Pain in the upper right portion of the abdomen usually corresponds to problems with the liver. The liver produces bile (also known as gall), which is a dark green to yellowish brown fluid that helps most vertebrates with digestion. It increases the absorption of fats and fat-soluble substances such as vitamins A,D,E, and K. It is also necessary for the excretion of bilirubin, which is a byproduct when red blood cells are recycled by the liver.

Bile deficiency can cause the fats in the food to be undigested and these fats end up excreted as part of feces. It can also lead to vitamin deficiency and a gradual build-up of toxins in the liver.

Reika [66]

The correct answer is nephron.
<span>
The nephron consists of Bowman’s capsule ( where blood is initially filtered ) and glomerulus which is a tuft of capillaries. Bowman’s capsule and a glomerulus together form the renal corpuscle. The renal tubule extends from the capsule and it consists of proximal convoluted tubule (selective reabsorption), a loop of Henle (establishes a salt gradient) and distal convoluted tubule (selective reabsorption). </span>

When oxygen is available,<br>cellular respiration takes place.

nexus9112 [7]

Cellular respiration is a process that all living things use to convert glucose into energy. Autotrophs (like plants) produce glucose during photosynthesis. Heterotrophs (like humans) ingest other living things to obtain glucose. While the process can seem complex, this page takes you through the key elements of each part of cellular respiration.

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. Glycolysis is an anaerobic process, while the other two pathways are aerobic. In order to move from glycolysis to the citric acid cycle, pyruvate molecules (the output of glycolysis) must be oxidized in a process called pyruvate oxidation.

Glycolysis

Glycolysis is the first pathway in cellular respiration. This pathway is anaerobic and takes place in the cytoplasm of the cell. This pathway breaks down 1 glucose molecule and produces 2 pyruvate molecules. There are two halves of glycolysis, with five steps in each half. The first half is known as the “energy requiring” steps. This half splits glucose, and uses up 2 ATP. If the concentration of pyruvate kinase is high enough, the second half of glycolysis can proceed. In the second half, the “energy releasing: steps, 4 molecules of ATP and 2 NADH are released. Glycolysis has a net gain of 2 ATP molecules and 2 NADH.

Some cells (e.g., mature mammalian red blood cells) cannot undergo aerobic respiration, so glycolysis is their only source of ATP. However, most cells undergo pyruvate oxidation and continue to the other pathways of cellular respiration.

Pyruvate Oxidation

In eukaryotes, pyruvate oxidation takes place in the mitochondria. Pyruvate oxidation can only happen if oxygen is available. In this process, the pyruvate created by glycolysis is oxidized. In this oxidation process, a carboxyl group is removed from pyruvate, creating acetyl groups, which compound with coenzyme A (CoA) to form acetyl CoA. This process also releases CO2.

Citric Acid Cycle

The citric acid cycle (also known as the Krebs cycle) is the second pathway in cellular respiration, and it also takes place in the mitochondria. The rate of the cycle is controlled by ATP concentration. When there is more ATP available, the rate slows down; when there is less ATP the rate increases. This pathway is a closed loop: the final step produces the compound needed for the first step.

The citric acid cycle is considered an aerobic pathway because the NADH and FADH2 it produces act as temporary electron storage compounds, transferring their electrons to the next pathway (electron transport chain), which uses atmospheric oxygen. Each turn of the citric acid cycle provides a net gain of CO2, 1 GTP or ATP, and 3 NADH and 1 FADH2.

Electron Transport Chain

Most ATP from glucose is generated in the electron transport chain. It is the only part of cellular respiration that directly consumes oxygen; however, in some prokaryotes, this is an anaerobic pathway. In eukaryotes, this pathway takes place in the inner mitochondrial membrane. In prokaryotes it occurs in the plasma membrane.

The electron transport chain is made up of 4 proteins along the membrane and a proton pump. A cofactor shuttles electrons between proteins I–III. If NAD is depleted, skip I: FADH2 starts on II. In chemiosmosis, a proton pump takes hydrogens from inside mitochondria to the outside; this spins the “motor” and the phosphate groups attach to that. The movement changes from ADP to ATP, creating 90% of ATP obtained from aerobic glucose catabolism.

Yes she will fall under her doctor's recommendation because she is taking prescribed amount of carbohydrate in one serving which can affect her blood sugar level and dietry fibre will have no effect on sugar level so separate portion can be taken.

Explanation:

Dietary fibres are also carbohydrates called cellulose which is not digested in our bodies. The addition of cellulose is just for adding roughage to the diet as it provides bulk to the diet.

The carbohydrate intake is very important in the meal plan as it readily provides energy. The glucose is the most easily used form of energy from the body in comparision to fat and proteins. The energy yield is 4 calories per 1 gram of carbohydrates.

The recommendations by doctor to Brianna is to have 30 grams of carbohydrate and can have dietry fibre in different portion. Thus, if she eats two servings for the diet she is following the instructions.

The dietry fibre has no effect on her sugar level but carbohydrate increment will cause raise in sugar level as insulin production gets down in diabetics and not using the carbohydrate as fuel.
