A microscope is an instrument used in Biology which is used to see organisms that are not possible to be seen by the naked eye. Through advancement, from 2-D images, 3-D images are already obtained from microscopes including scanning-electron microscope and digital microscope.
Answer: option A
Explanation: As demonstrated by the Hardy-Weinberg principle, the dominance or recessiveness of an allele does not determine its frequency in a population.
The correct answer is: cerebral cortex (prefrontal).
Cerebral cortex is the outer layer of cerebrum and it is the neural integration area of the brain. Globally, the role of cerebral cortex is role in memory, attention, perception, awareness, thought, language, and consciousness.
Prefrontal cortex is part of the cerebral cortex (cover the front part of frontal lobe). It is involved in complex social behavior of the human, complex cognitive behavior, decision making.
Answer:
The correct answer is B. Myopia is also known as nearsightedness.
Explanation:
Myopia is a refractive defect of the eye in which parallel light rays converge at a focal point located in front of the retina, instead of converging on the same retina; it is the inverse defect to farsightedness, in which the light rays reach the retina before converging.
A person with myopia has difficulty focusing well on distant objects, which causes visual acuity deficits and can also lead to headaches, strabismus, visual discomfort and eye irritation.
Answer:
Animals can move, but plants cannot
Explanation:
Locomotion in humans and bipeds is accomplished through walking on legs. In other animals, it can be accomplished through walking on four limbs, flying, or swimming. In cells, cilia and flagella are used to move about. However, since plants are not capable of moving themselves, there is no locomotion of plant species.
