Answer:
so the a goes down and up and then it finds two pretty bestfriends
<h2>Order of parts of a microscope
</h2>
First – ocular lens
Second – Body tube
Third – Revolving Nosepiece
Fourth – Objective lens
Fifth – Coverslip
Explanation:
Ocular lens: The lens present in the eyepiece at the top of the microscope, close to the eyes, through which a person looks through the microscope to view the specimen. Magnification of ocular lens in a compound microscope is usually 10x
Body tube: The tube that connects the eyepiece with the objective of the microscope for continuous optical alignment.
Revolving Nosepiece: The turret that holds the objective and revolves to select the objective lens according to its magnification
Objective lens: The objective lens is located above the specimen rack. Objective lens creates the primary image of the specimen viewed through the eyepiece. A single compound microscope can have more than two objective lens and their magnification ranges from 4x, 10x, 40x, 100x power.
Coverslip: The cover glass which covers the objective lens and prevent from touching the specimen
. This is the object directly above the specimen.
Answer: Animals, plants, and bacteria.
Explanation: The phylogenetic tree is used to show similarities of organisms based on the genetics and possible shown features. Bacteria over time can evolve jus trike plants and animals, thus concluding that bacteria, plants, and animals can all be constructed on a phylogenetic tree.
Most barnacles are filter feeders, sometimes known as “suspension feeders.” They feed on plankton and detritus (dead organic material), which they either sweep from the water into their mouths, using their fan-like feet, or they rely on the movement of the tide to bring the food to them.
Answer:
D. stable environments
Explanation:
In the gradual speciation model, changes in species are slow over time that occur in small steps. Change in speciation rate influences two factors that are environmental conditions and population size.
Gradual speciation mostly occur in large populations that move towards evolution and live in a stable environment. The stable environment provides enough time for the evolution to happen and stable habitat for the new species to grow slowly.
Hence, the correct answer is "D. stable environments".
