Ques: Q: What is the medial bone of the forearm that runs parallel to the radius? Read this paragraph and choose the correct option from the provided answers: Ulna The ulna is the medial bone of the forearm. It runs parallel to the radius, which is the lateral bone of the forearm (Figure 8.6). The proximal end of the ulna resembles a crescent wrench with its large, C-shaped trochlear notch. This region articulates with the trochlea of the humerus as part of the elbow joint. The inferior margin of the trochlear notch is formed by a prominent lip of bone called the coronoid process of the ulna. Just below this on the anterior ulna is a roughened area called the ulnar tuberosity. To the lateral side and slightly inferior to the trochlear notch is a small, smooth area called the radial notch of the ulna. This area is the site of articulation between the proximal radius and the ulna, forming the proximal radioulnar joint. The posterior and superior portions of the proximal ulna make up the olecranon process, which forms the bony tip of the elbow. Choices: - humerus - fibula - radius - ulna A:
Ans: ulna

Ques: Q: What is the process in which an atom becomes an ion known as? Read this paragraph and choose the correct option from the provided answers: The process in which an atom becomes an ion is called ionization. It may occur when atoms are exposed to high levels of radiation. The radiation may give their outer electrons enough energy to escape from the attraction of the positive nucleus. However, most ions form when atoms transfer electrons to or from other atoms or molecules. For example, sodium atoms may transfer electrons to chlorine atoms. This forms positive sodium ions (Na + ) and negative chloride ions (Cl - ). You can see an animation of this process at the URL below. Choices: - electrification - evaporation - oxidation - ionization A:
Ans: ionization

Ques: Q: Who is called the father of genetics? Read this paragraph and choose the correct option from the provided answers: People have long known that the characteristics of living things are similar in parents and their offspring. Whether it's the flower color in pea plants or nose shape in people, it is obvious that offspring resemble their parents. However, it wasn't until the experiments of Gregor Mendel that scientists understood how characteristics are inherited. Mendel's discoveries formed the basis of genetics , the science of heredity. That's why Mendel is often called the "father of genetics. " It's not common for a single researcher to have such an important impact on science. The importance of Mendel's work was due to three things: a curious mind, sound scientific methods, and good luck. You'll see why when you read about Mendel's experiments. Choices: - Nostradamus - Vincent van Gogh - raphael - mendel A:
Ans: mendel

Ques: Q: A mitotic spindle forms from the centrioles and passes through the nuclear membrane, which remains intact. chromosomes attach to the mitotic spindle, which separates the chromosomes and does what? Read this paragraph and choose the correct option from the provided answers: A mitotic spindle forms from the centrioles and passes through the nuclear membrane, which remains intact. Chromosomes attach to the mitotic spindle, which separates the chromosomes and elongates the cell. Choices: - manipulates the cell - migrates the cell - destroys the cell - elongates the cell A:
Ans:
elongates the cell
