-Listening to Earth - How is this related to plate boundaries?

Biology

Listening to Earth is an article about the study of the plate boundaries using hydrophones which make noises and different sounds.

<u>Explanation:</u>

Listening to Earth is an article which was written about the studying of the plate boundaries by Dziak and his team. Since it is tough to send people to the bottom surface of the ocean, they made use of hydrophones making them listen to various sounds.

These sounds are made by the movement and the motions of the plate boundaries from their original position which many a times lead to the earthquakes.

Which is the first step in the contingency planning process among the options listed here?
AVprozaik [17]

Business Impact Analysis

Business Impact Analysis (BIA) refers to the method of determining the potential risks that a business will encounter when disaster strikes. It is the first step in the contingency planning process. Large businesses with strong disaster recovery planning programs put BIA into their programs, making it one of the important stages. Unless BIA has been conducted, the disaster recovery programs will not be fully developed since the output of BIA will ascertain the strategies and policies that will be in the disaster recovery program of the company.

Allen pours water into a graduated cylinder. He notices that the surface of the water is curved, as shown below.
Slav-nsk [51]

Answer:

When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).

Explanation:

A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.

<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.

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.
