Answer:

Climate change is partly the result of an increased concentration of greenhouse gases, especially carbon dioxide

Explanation:

Increased concentration of carbon dioxide, leads to change in temperature because it traps the heat in the Earth's atmosphere. For greenhouse, carbon dioxide is the main gas. The other green house gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Absence of the greenhouse leads to the average temperature of about -18 degree Celsius. But when these gases are present the average temperature is about 15 degree Celsius.

Two sets of data that show a relationship is an example of correlation.

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

Correlation is the relationship between two sets of data. Correlation in statistics help in determining whether two or more sets of data fluctuate in accordance with one another or not. And if they do, the degree of fluctuation can also be determined and studied.

By determining how one or two variables or data are related to one another, we can understand how to manipulate the values. In correlation, there are following possibilities:

When one value increases, the other decreased
When value increases or decreases, the other changes in the same way.

Example of correlation:

The utility of an air-conditioner increases as the temperature in the said area increases.

Complete the passage to describe the link between photosynthesis and respiration.

Butoxors [25]

Answer:

Explanation:

The reactants for cellular respiration are the products of photosynthesis. The products of cellular respiration are the reactants in photosynthesis.

During photosynthesis, green plants manufacture their food using sunlight to synthesize glucose from water and carbon dioxide.
The other product of the process is oxygen gas.
During cellular respiration, the glucose is combined with oxygen to produce energy, carbon dioxide and water.

Answer:

The nucleic acid is a macromolecule present in living systems in the form of either DNA or RNA, whose molecule consists of many nucleotides which are linked with each other to form long chains. The presence of DNA or RNA in an individual promotes continuity of life. The variability and complexity of nucleic acid are dependent on its constituent molecules as, sugar, a phosphate group, and a nitrogenous base. However, two monocyclic nitrogenous bases were classified purines (adenine:A, guanine:G) and pyrimidines (thymine:T, cytosine:C, and uracil:U).

In addition, RNA is a single-stranded structure which differs from DNA in two aspects, the sugar content of RNA is ribose, and pyrimidine base uracil replaces the thymine base of DNA. A ratio between two strands of DNA can be calculated by using Chargrff's rule which states that "DNA from any cell of all organisms possess a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases'.

The purine to pyrimidine ratio in RNA with different bases is given below in the following table:

Presence of single strand in RNA does not follow chargaff's rule and alters the purine: pyrimidine ratio. The above ratio of each base in the given information is not equal, due to which the ratio of purines to pyrimidines is different. The ratio of DNA and RNA is not equal because DNA has its complementary DNA strand. However, bases in RNA might vary due to its single-strandedness property, but its ratio is dependent on the species.

Therefore, it can be concluded that the ratio of purines to pyrimidines is dependent on the species due to its genetic makeup. Hence, option (c) is correct.
