kenny6666 [7]2 years ago
8 0

Answer:

chips made from silicon

Explanation:

Non renewable resources are natural substances that cannot be replenished when used for eg natural gas, coal, petroleum ,fossil fuels etc. Silicon is made when silica is heated with carbon after which the the product is reacted with hydrocarbons to polymerize them. Since the hydrocarbons are made from natural gas, oil ,it is non renewable

Name two substances in the body that will move based on the principles of diffusion
Nina [5.8K]
Hello there!

The principle of diffusion consists in the movement of substances through a membrane from a zone with high concentration, to a zone with low concentration, until the concentration is equal on both sides of the membrane. 

An example of diffusion is the process that happens when we breathe. Two substances in the body that will move based on the principles of diffusion are Carbon Dioxide and Oxygen. Carbon Dioxide will move from the bloodstream to the alveoli, and Oxygen will move from the alveoli to the bloodstream.

Which of the following statements correctly describes some aspect of ATP hydrolysis being used to drive the active transport of
saw5 [17]

Answer:

B) This is an example of energy coupling

Explanation:

Energy coupling is a process by which cells carry out thermodynamically unfavorable, endergonic (energy-requiring) reactions to other exergonic (reactions that liberate free energy) reactions.

Reactions which are endergonic do not occur spontaneously as they result in a decrease in entropy and a positive free energy change, ∆G.

Exergonic reactions occur spontaneously as they result in an increase in entropy and have a negative free energy change, ∆G.

For example, the active transport of ions against their concentration gradients in cells is a non-spontaneous endergonic process which is coupled to the hydrolysis of ATP, an exergonic process in other for the reaction to proceed. ATP hydrolysis phosphorylates an amino acid side chain in the transport protein which then drives the forward process of transport of the ion.

Considering the above,

Option A: The hydrolysis of ATP is endergonic, and the active transport is exergonic is false because ATP hydrolysis is exergonic while active transport is endergonic.

Option B: This is an example of energy coupling is true.

Option C: Both ATP hydrolysis and active transport are spontaneous because they result in an increase in entropy of the system is false because only ATP hydrolysis is spontaneous

Option D: Neither ATP hydrolysis nor active transport is spontaneous is false because ATP hydrolysis is spontaneous.

Option E: ATP is acting as a transport protein to facilitate the movement of the ion across the plasma membrane is false because ATP is not a protein, rather it serves to activate the transport protein by phosphorylating it.

Learning Competencies: 1. Explain how protein is made using information from DNA. 2. Explain how mutation may cause changes in t
olga2289 [7]

Answer:

The correct answer is -

1. protein synthesis or central dogma

2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.

Explanation:

1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.

2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.

Passive transport does not use ATP andfollows a concentration gradient<br> False or <br> True
inysia [295]

Answer:

True

Explanation:

Since it's a passive way of transport, it is in favor of the concentration gradient and does not need to use ATP.
