Macrophages kill the cellular debris of the pathogens that are killed by the immune system. They are a type of white blood cells, and kill anything which does not have the proteins that are specific to the healthy cells of the body. Cancer cells, foreign substances, and microbes are engulfed by them.
Explanation:
Locomotion bacteria, protists and fungi The movement for living beings can be the difference between living and dying, some of the bacteria have the ability to move through two mechanisms: movement by flagella and movement by sliding Movement by phalanges: in bacteria, the Flagella are thin and elongated structures that remain attached to the cell by one end. The flagella are made of a protein called flagelin and its shape is helical, for the movement the flagellum has a system called an engine that is at the base and the wall is connected to the membrane. The motor system works driven by protons that move thanks to the action of the proteins of the base of the scourge., The rotation and movement of the scourge are not constant and depend on stimuli. The flagella are arranged differently according to the type of bacteria, there are peritic, lofotrica and polar flagella.
Answer:
b
Explanation:
The carbon dioxide coming from our vehicles is really affecting the ozone layer
Answer:
C
Explanation:
These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.
Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.
We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.
I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.
