Answer:

SIMILARITIES:

  • Both photosynthesis and aerobic respiration are biochemical processes.
  • Both processes make energy.
  • Both are reduction-oxidation reactions.
  • The electron transport chain is required in both.
  • The process of chemiosmosis can be seen in both processes.

DIFFERENCES

1. In the reaction for cellular respiration, a glucose molecule combines with an oxygen molecule and energy is released. Water and carbon dioxide are the by-products of this reaction. In a photosynthetic reaction, water and carbon dioxide combine in the presence of light energy to form glucose and oxygen. Hence, both the processes are opposite of each other.

2. The process of photosynthesis occurs in the chloroplast whereas the process of aerobic reaction occurs in the mitochondria.

3. In photosynthesis, light energy is converted into chemical energy whereas, in respiration, chemical energy released by oxidizing food is used to form ATP.

Which two scientists are accredited with correctly deducing the double helix model of dna.
Vika [28.1K]

Answer:

James Watson and Francis Crick

Explanation:

Watson, Crick, Franklin, and Wilkins were four scientists that discovered the double-helix structure of DNA, which served as the foundation for modern biotechnology.

Franklin used X-ray crystallography at King's College London to acquire pictures of DNA, a notion previously proposed by Maurice Wilkins. Franklin's photographs led James Watson and Francis Crick to develop their renowned two-strand, or double-helix, model.

During DNA replication each stands of dna is used as a temple to produce a complementary stand of DNA this process is shown belo
castortr0y [4]
<h2><u>Full question:</u></h2>

During DNA replication, each strand of DNA is used as a template to produce

a complementary strand of DNA. This process is shown below. Which base

will attach to location 2?

A. Adenine B. Allimene C. Thymine D. Tyrosine

<h2><u>Answer:</u></h2>

Base thymine will get attached the location 2.

Option C

<h3><u>Explanation:</u></h3>

DNA replication is the process by which the genetic material that is deoxyribonucleic acid is getting replicated into its daughter DNA by the process which involves a lot of enzymes and energy. This process involves the formation of complementary base pairing between the nitrogen bases present in the nucleotides of DNA.

As the DNA replication starts the enzymes helicase and gyrase comes in action which open up the double stranded DNA which then is acted by DNA dependent DNA polymerase which gets attached to the coding strand of the DNA and starts accumulating the nucleotides from the cytoplasm and nucleoplasm that are complementary to the nitrogen base that is present on the coding strand. This process is very fast and can go up to speed of 30 to 40 base per second. This process is fully based on the complementary base pairing nature of DNA which bring the nucleotide from the nucleoplasm that is complementary to the base present on the coding strand. And this nucleotide is the same that is present on the other strand of the DNA because the DNA double helix contains the the complementary bases that actually forms hydrogen bond between themselves.

Here in the location to we can see that adenine is present as the nitrogen base. The complementary base to adenine is thymine. So the complementary base that will be present there will be thymine itself

Sort the items based on whether they have gravitational potential energy or chemical potential energy. liquid petroleum gasoline
poizon [28]

Explanation:

Gravitational potential energy is the energy of body due to its position in the gravitational field.

Whereas chemical potential energy is the energy within the chemical bonds of a substance.

For example, when we eat an apple then we get energy in our body so, it is the chemical potential energy stored in the apple.

Items sorted on the bases of gravitational potential energy and chemical potential energy are as follows.

Gravitational potential energy:

  • a ball thrown up in the air.
  • a stone rolling downhill.
  • water stored in an overhead tank.

Chemical potential energy:

  • liquid petroleum gasoline used in cars.
  • apples that people eat.
  • firecrackers that people set off.

Serga [27]

Explanation:

we can track climate patterns back to us on earth and the excessive use of fossil fuels and other gasses contribute to this - its basically proven that we are the reason climate change is a thing. climate will change by itself by us humans are causing this to be much faster than it should be
