This is the case for the flu shots, the weakened viruses activate lymphocytes to produce antibodies while the viruses are quickly eliminated.

Lilit [14]
Bugs with shorter bills had more access to sustenance, enabling them to deliver all the more posterity. Bugs that happened to have short breaks were better ready to feast upon the little organic products. Their expanded access to nourishment enabled them to deliver all the more posterity, which likewise had little snouts. In any case, bugs with little bills did not emerge so as to feast upon the little natural products. Transformative change comes to fruition as the extent of people in the populace showing a specific characteristic increments from age to age. The characteristic does not change step by step in all individuals from the populace.

The pH of a solution containing 0.1 mM H+ is _______ ( 1mM = 10-3M)
Taya2010 [7]

Answer:

The pH of a solution containing 0.1 mM H+ is 4

Explanation:

The pH of any solution is given by the following mathematical equation -

pH = -log[H_{+}]\\----------- Equation (A)

Where,

H_{+} = the concentration of hydrogen ion in the solution.

Given

H_{+}

= 0.1mM\\=0.1 * 10^{-3}\\= 10^{-4}\\

Substituting the given value in equation (A) , we get -

pH = -log[10^{-4}]

= -(-4)\\= 4

Hence, The pH of a solution containing 0.1 mM H+ is 4

Drag each tile to the correct location.
OLEGan [10]

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
