Explanation:
deforestation can affect competition of food for example when we cut plants for different purposes the animals that eat the plants will starved and die in this cause if want to eat animals products we could not get because animals are died because of the deforestation this cause food competition between human and animals
The statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope is as follows:
- Compound light microscopes have higher magnification.
Thus, the correct option for this question is C.
<h3>What is a Microscope?</h3>
A microscope may be defined as a type of laboratory instrument that is significantly utilized to examine or observe objects that are too small to be visualized by the unaided eye.
Dissecting microscopes possess a lower magnification power as compared to compound light microscopes. Due to this, dissecting microscopes are used to visualize larger objects like tissues. Compound light microscopes use more than one glass lens. These types of microscopes are used to examine living cells.
Therefore, a compound light microscope has higher magnification is a statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope. Thus, the correct option for this question is C.

Answer:
A. NADH and FADH2 both donate electrons at the same location.
Explanation:
In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.
These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.
Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.
NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.
The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.
If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.
Answer:
The movement of the replication fork is accomplished by the enzyme helicase, which breaks hydrogen bonds between the paired bases and unwinds the double helix ahead of the advancing DNA polymerase.
