The inflammatory disease of the central nervous system that attacks the myelin sheath is known as MULTIPLE SCLEROSIS
I hope it helps
The amount of water vapor in the air is calledrelative humidity
Answer:
Plant-like:
presence of flagella
shows the absence of cell wall, though chloroplast may be present
Animal-like:
absence of cell wall, as well as chloroplast
Fungus-like:
feeds on decaying matter
enclosed by a membrane called a pellicle
slime mold belongs in this category
Explanation:
The protists can be classified into three groups (plant-like, animal-like, fungus-like) based on the method of nutrition, movement, and mode of reproduction.
Plant-like protists have chloroplasts and trapped sunlight to form food ad energy (photosynthesis). They also have flagella used for the movement.
Example: Algae
Animal-like protists are heterotrophs that cannot make their food. They do not have chloroplast and cell wall outside the cell membrane.
Example: Protozoa
Fungus-like protists are single-cell eukaryotes that have a protective layer outside the cell membrane called pellicle. They feed on decaying organic matter.
Example: Slime mold and water mold
Answer:
The relative frequency of the mutation will increase as time passes.
Explanation:
This random mutation has, by chance, caused a phenotype that is beneficial to the bacteria. This mutation improves the fitness of the bacteria, as they are able to utilize more food sources. This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.
In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.
