In his attempt to develop a pneumonia vaccine, Frederick Griffith injected mice with various combinations of living and dead bac
n200080 [17]

Answer:

The mice died

Explanation:

In Griffith's experiment, two strains of the same bacteria were used. S strain was smooth because it had a polysaccharide coat. This coat also made it virulent because mouse immune system was not able to destroy it and ultimately the mice died. R strain was rough because it did not have the coat and thus was harmless to mice.

When Griffith injected mice with dead S bacteria and living R bacteria together, the mice died. Live R bacteria had taken up the genetic material or as Griffith called "transforming principle" from the dead S bacteria and transformed into S bacteria. So live S bacteria were present again and they killed the mice.

2. A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which stat
quester [9]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ The correct answer would be D. Products of one process are used as some of the reactants for the other processes.

As you may know, the formula for photosynthesis is:

carbon dioxide + water ==> oxygen + glucose

And the formula for respiration is:

oxygen + glucose ==> carbon dioxide + water

The reactants for one are the products for the other and vice versa. This is why it would be the correct option.

➶ Good Luck (:

➶ Have A Great Day ^-^

Over many generations darker for color becomes more common in a population of squirrels living in a shady area
PIT_PIT [208]

The answer is letter b. adaptation. Adaptation occurs when living organisms adapt to their surroundings or environment over a long period of time. In this case, Dark Furred Squirrels were abundant, since squirrels adapted to the dark shady area they have lived and adapted into a dark furred one, which allowed it to be more common due to adaptation.
