Answer: True. Selective media can be used to separate gram negative from gram positive bacteria.
Explanation: Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms.
For example: Media containing potassium tellurite will inhibit the growth of gram negative bacteria while media supplemented with penicillin will inhibit the growth of gram positive bacteria.
Answer:
D. It provides a way to increase the
frequency of beneficial traits in a
population.
Explanation:
Artificial selection is a selection made by the human intervention. Artificial selection is better than natural selection because in natural selection organisms mate naturally with each other while in artificial selection, human selects good traits organisms to mate with each other and produce offspring which has better characteristics than parents.
Answer:
the last choice
Explanation:
specific heat is the amount of heat required to raise the temperature this eliminates choice 1 and choice 3 and then the question doesn't specifically mention just water leaving choice 4 which is the answer
That would be the ER (endoplasmic reticulum) and the Golgi apparatus.
Answer:
This question is asking to state what is being defined. The term defined in the question is called DIFFUSION
Explanation:
Diffusion is the movement of particles/fluids from a region where they are highly concentrated to the region where they are less in concentration across a space. Diffusion is a form of passive transport i.e does not require energy input to occur. This is because the movement occurs down a concentration gradient.
A concentration gradient i.e difference in concentration occurs when there is an uneven amount/concentration of particles in two regions. Hence, movement occurs naturally to the direction where the particles are less concentrated from where they are more concentrated.
