The option that best describes viruses is: Viruses are nonliving infectious agents. thus option A is correct.
A virus is an infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria.
Viruses cannot replicate on their own and they need a host cell in order to survive. Antibiotics kill bacteria but not viruses. Antivirals and vaccines are made available to decrease the production of viruses, but not totally stopping them. Bacteria and virus differ in so many ways. so, option A is correct.

Microscope are the important tools which are used by scientist. For example, in material science, medicine, mineralogy and microbiology.
Light microscope is able to send light. Light is being focused in a tight breath whereby that light passes through a sample which later it is able to create an image. This image passes to different lenses which magnifies it until it reaches the camera.
There are different types of microscope for example, Compound light microscope, Simple light microscope, and monocular microscope.
In simple light microscope only one lens which which is being used to magnify an object and it is not able to reach to a higher magnification.
In compound light microscope it uses two lenses to produce image. For example eyepiece lens and objective lens.
Answer:
We learned how to prepare the object, how to focus the object, and how to correctly put the microscope away safely. It taught me that you have to start with the smallest magnification on the microscope and then after you have the specimen lined up then you can turn the nose piece to a larger magnification to get a closer look on the specimen.
Explanation:
A species in a changing environment would have the best chance of survival as a result of a mutation that has high adaptive value and occurs in its gametes. Thus, the correct option is C.
A Mutation is defined as which occurs when a deoxyribose nucleotide acid gene is damaged or altered in such a way as to change the genetic message carried by that gene.
All the mutations which affect the fitness of future generations are agents of evolution.

Answer: A. Julie loves chicken noodle soup, but her cold is making it taste bland.
Sensory interaction is the interaction among various sense organs of the body. It depicts how one sense organ influence the response from other sense organ. Taste and smell are examples of senses which are dependent on each other and can influence the response generated by external stimuli. For example, food tastes are bland when a person is not able to inhale it's smell. Julie loves chicken noodle soup, but her cold is making it taste bland. Here, the taste of noodle depends upon smell of food as, Julie is not able to inhale the smell of food therefore, the taste is bland. Hence, this illustrates the best example for sensory interaction.
