<span>The common difference between the three organisms
is the area in which they specifically live or stay in the ocean. Planktons can’t
be seen by the naked eye and they require microscopes to be detected. Planktons
usually float in the water and they cannot move on their own that’s why they
are dependent in the movement of the water.
Nektons are organisms that swim through the water and they live in different
depths in the ocean ecosystem. Nektons are composed of fish and other mammals
that propel themselves through the water.
Benthos are organisms that live in the ocean floor and many of these organisms
stay in one place by attaching themselves to rocks. This adaptation protects
them from crashing waves and drastic water movements. Other benthos are known
to burrow in the ocean floor either for food or protection.</span>
Answer: Pelvic and sternum
Explanation:
bone marrow biopsy is a procedure that is used to obtain bone marrow usually with syringe for evaluation of various blood cells( leucocytes, erythrocytes ) and also for examination for different blood disesases such as leukemias and lymphomas and diagnose some genetic conditions. The common site for a bone marrow biopsy is the large pelvic bone near the hip and also some samples taken from the sternum (breastbone).
A bone marrow examination or test consists of two separate tests that are done at the same time namely:
1. Bone marrow aspiration that helps collect sample of the liquid portion of the bone marrow
2. Bone marrow biopsy that obtains a sample of the solid material.
Natural ladybugs.
You can indeed use ladybugs in a pest control, but that depends on the pest. Since in the question, you don't specify what the pest is, the answer is natural ladybugs.
If the animal was something that ladybugs eat, like aphids for example, than ladybugs could be used as a pest control insect.
