Answers

Answer:

C broken down into amino acids.

Explanation:

Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.

In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose

A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made

Answers

Answer:

D)NADPH is made

A)ATP is used

Explanation:

Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]

The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:

Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).

Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis).

Conversely, the Calvin cycle regenerates ADP and NADP^+

There are _____ levels of intellectual disabilities on the modern continuum.

A.
five
B.
four
C.
three
D.
two

Answers

Answer:

B) Four

Explanation:

There are four levels of intellectual disabilities on the modern continuum. The correct option is B.

What are intellectual disabilities?

A person is said to have an intellectual disability when their capacity to learn at a typical rate and function in daily life is restricted. The severity of intellectual disability in children varies widely.

Despite the fact that a precise full-scale IQ test result is no longer necessary for diagnosis, standardised testing is nevertheless used to help make the diagnosis.

A full-scale IQ score of between 70 and 75 denotes a considerable intellectual functioning restriction.

Each person's level of difficulty with learning and processing information, difficulties with abstract cognition, and issues with social interaction are all common aspects of intellectual impairments.

On the contemporary continuum, there are four stages of intellectual disability.

Thus, the correct option is B.

How would the disappearance of shrimp, copepods, and amphipods affect the other organisms in the ocean food web

Answers

The disappearance of shrimp who cause whale numbers to decrease because they are a main food source for whales. And if copecods were to disappear it would cause a problem with microscopic algal cells and phytoplankton who’s populations would increase. And amphipods play an important role in marine and freshwater ecosystems. So if they were to disappear they would be more dead creatures around because they are scavengers and eat dead or decaying algae.
