B. disregard the findings of that study completely, without proof or reason.
C. perform experiments to validate or disprove the findings of that study.
B. depleting the world's ozone
C. causing salinization
D. increasing soil erosion
The correct answer is D. Increasing soil erosion
Explanation:
Mining refers to the process of extracting minerals such as coal, chalk, limestone, etc that are usually placed on underground deposits. Because of this, mining often involves excavation, although other methods use substances and chemicals to extract the mineral. In all of this cases, the natural properties of the soil are negatively affected as vegetation is often removed along with multiple soil layers, this leads to soil erosion due to the damage in the soil and the lack of vegetation that make the soi dry and in most case infertile. Therefore, one way mining for mineral resources damages land is by increasing soil erosion.
B) Different species share the same space.
C) A population is divided.
D) A major change on earth takes place.
2. Which of the following must be true of their individuals if two populations are no longer the same species?
A) They do not have any of the same genes.
B) They do not share any of the same space.
C) They do not resemble each other at all.
D) They cannot reproduce successfully with each other.
3. How does speciation start to take place on a genetic level between two isolated populations?
A) Large numbers of mutations occur.
B) Allele frequencies change in different ways.
C) New genes are added to one group.
D) Recessive alleles become dominant.
The 3rd question is actually B. Allele frequencies change in different ways
Cell respiration occurs in animal cells and not plant cells.
Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.
Photosynthesis uses light as energy source, and cell respiration uses chemical energy.
Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy
Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.
Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.
Photosynthesis uses light as an energy source, while cell respiration uses chemical energy. Therefore option d. is the correct answer.
The correct statement that distinguishes photosynthesis and respiration is:
Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.
In photosynthesis, plants convert light energy into chemical energy, specifically glucose. This process occurs in the chloroplasts of plant cells.
On the other hand, cell respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).
This process occurs in both plant and animal cells, specifically in the mitochondria.
Therefore, photosynthesis uses light as its energy source, while cell respiration uses chemical energy.
Therefore option d. is the correct answer.

B: rRNA genes
C: amino acid sequences of proteins
D: noncoding repetitive repeats and intron regions
E: specific proteins that are made by a cell under particular conditions
Answer:
E: specific proteins that are made by a cell under particular conditions
Explanation:
It is only specific proteins that are made by a cell under particular conditions can't be obtained from a genome sequence. In order to get information about this protein we need proteomics.
Genome sequence gives us an idea of nucleotide sequence of DNA and RNA molecules not proteins. Regulatory sequences such as promoters, enhancers, insulators, UTRs etc. all are a part of genome, rRNA genes are part of genome sequence too, non coding repetitive repeats and intron regions are also a part of genome sequence itself so option A, B & D are incorrect. Option C is also incorrect because amino acid sequence of proteins can also be determined by genome sequences because each nucleotide triplet which is known as codon refers to a specific amino acid. Option E is correct because by genome sequence we can easily get to know about amino acid sequence but not about specific protein which is synthesized at a particular condition.
