Answer:
All are methods to separate mixtures
Explanation:
<em>A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.</em>
Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.
Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.
<u>Hence, all the methods listed are used to separate mixtures.</u>
Answer:
Goblet Cells
Explanation:
HCL in the lumen doesn't digest the mucous because goblet cells in the mucous secrete large quantities of protective mucus that line the mucous surface.
In simple terms, our stomach has enzymes which allow it to be protected against the hydrochloride acid.
Answer:
The correct options is B.
Explanation:
Evolution has to do with the changes that occur in a particular population of organism as a results of environmental changes and other pressure that the population is exposed to and how the organism adapt to counter the changes.
Out of all the options given in this question, the individual that is most likely to be successful in an evolutionary sense is the one describe in option B. This is because, the organism has a short life span of five days and it left behind ten children that are capable of reproducing. Evolution is a process that occur over a long period of time. So, if it an environmental change occur in the environment where the organism lives, it will be easier for the new generation and the subsequent generations of the organism to adapt to the change.
Those organisms that have long life span will not be able to adapt as easily as the organisms in options B because it will take many years and many generations for them to do that.

after/sweeping floor and wash hands again
washing hands can go either or both. :)
