Q: The atomic number is the same as the number of what in an atom? Read this paragraph and choose the correct option from the provided answers: The number of protons in an atom is called its atomic number. This is also unique for each element. Choices: - neutrons - ions - electrons - protons A:
protons

Q: What are two major categories of mutations? Read this paragraph and choose the correct option from the provided answers: There are a variety of types of mutations. Two major categories of mutations are germline mutations and somatic mutations. Choices: - homologous and somatic - german and somatic - plasticity and somatic - germline and somatic A:
germline and somatic

Q: Q: What can be described as a tiny male gametophyte enclosed in a tough capsule? Read this paragraph and choose the correct option from the provided answers: A grain of pollen is a tiny male gametophyte enclosed in a tough capsule (see Figure below ). It carries sperm to an ovule while preventing it from drying out. Pollen grains can't swim, but they are very light, so the wind can carry them. Therefore, they can travel through air instead of water. Choices: - seed - cell - dna - grain of pollen A:
A: grain of pollen

Question: Q: Most motions in nature follow ________ rather than straight lines? Read this paragraph and choose the correct option from the provided answers: Introduction to Two-Dimensional Kinematics The arc of a basketball, the orbit of a satellite, a bicycle rounding a curve, a swimmer diving into a pool, blood gushing out of a wound, and a puppy chasing its tail are but a few examples of motions along curved paths. In fact, most motions in nature follow curved paths rather than straight lines. Motion along a curved path on a flat surface or a plane (such as that of a ball on a pool table or a skater on an ice rink) is two-dimensional, and thus described by two-dimensional kinematics. Motion not confined to a plane, such as a car following a winding mountain road, is described by three-dimensional kinematics. Both two- and threedimensional kinematics are simple extensions of the one-dimensional kinematics developed for straight-line motion in the previous chapter. This simple extension will allow us to apply physics to many more situations, and it will also yield unexpected insights about nature. Choices: - vertical paths - sharp paths - horizontal paths - curved paths A:
Answer: curved paths

Q: A crow that becomes used to a scarecrow and lands on it is an example of what? Read this paragraph and choose the correct option from the provided answers: Another example of habituation is shown below ( Figure below ). Crows and most other birds are usually afraid of people. They avoid coming close to people, or they fly away when people come near them. The crows landing on this scarecrow have become used to a "human" in this place. They have learned that the scarecrow poses no danger. They are no longer afraid to come close. They have become habituated to the scarecrow. Choices: - assimilation - adaptation - dissociation - habituation A:
**Answer**
habituation

(Question)
Q: What organ senses sound? Read this paragraph and choose the correct option from the provided answers: Hearing is the ability to sense sound waves, and the ear is the organ that senses sound. Sound waves enter the auditory canal and travel to the eardrum (see Figure below ). They strike the eardrum and make it vibrate. The vibrations then travel through several other structures inside the ear and reach the cochlea. The cochlea is a coiled tube filled with liquid. The liquid moves in response to the vibrations, causing tiny hair cells lining the cochlea to bend. In response, the hair cells send nerve impulses to the auditory nerve, which carries the impulses to the brain. The brain interprets the impulses and "tells" us what we are hearing. Choices: - teeth - brain - eyes - ear A:
(Answer)
ear
