Answer:
B. Early Eukaryotic cells engulfed mitochondria and chloroplasts
Explanation:
Mitochondria and Chloroplast are organelle that are found in cells of higher animals. Chloroplast are found almost exclusively in plants and mitochondria is found in animal cells. The function of these organelles are to produce energy to the cells, and by extension, the organism that they live in.
Unique features of these organelles show that they have their own DNA and divide and multiply on their own. This strongly suggest that they were once free living prokaryotes and were engulfed by larger cells and a symbiotic relationship began.
As time progressed, these prokaryotes did not require all of their genetic information and this was removed from their system. They kept essential genes and regulatory bodies separate that they needed for their maintenance and function that they provide.
Answer:
Cell adhesion molecules would help white blood cells to stick to the wall of the blood vessel, so they can permeate across the wall and go into the underlying injured tissue.
Explanation:
The cell adhesion molecules, also called CAMs, are a type of cell adhesion proteins on the cell's surface, they take part in the binding of other types of cells and work together with the extracellular matrix in the process of cell adhesion.
Long story short, the protein helps cells stick together or to the surrounding tissues, thus helping on the maintenance of tissue structure and function. In fully grown mammals (including humans), CAMs play an important and key role in creating force and movement, thus assuring the organs are able to execute their function.
In their role as "molecular glue", CAMs are important participants in the cellular mechanisms of growth, contact inhibition, apoptosis and diapedesis, and when their behavior goes haywire, they are associated with afflictions going from frostbite to cancer.
B, virtues.
A virtue is a trait or quality that is deemed to be morally good and is valued as a foundation of principle and good moral being. Personal virtues are characteristics valued as promoting collective and individual greatness.
