brilliants [131]

Answer:

B. Human toddlers walking

Explanation:

A bird feeding its young is innate, their kids need to eat and communicate it to their parents.

A child recoiling from a hot stove is a reactive behavior, they're not going to learn how to lift their hand from the stove, it's hot, they're going to move.

Squirrels opening nuts is also innate, they need food and opening nuts is how they get food.

Therefore the answer is B, human toddlers learn how to walk.

Answer:

See the answer below

Explanation:

From the graph, the concentration of salt solution where the number of burst red blood cells equals the number of intact ones is 0.40 g/100 cm3<u>.</u>

<em>At this concentration, the percentage of burst cells is 50, meaning that the remaining 50% of the cells in the experiment remained intact.</em>

The totality of the concentrations of all the salt solutions used is:

0.30+0.35+0.40+0.45+0.50 = 2 g/100 cm3

Thus, the percentage of salt solution concentration when the number of red blood cells that burst is the same as the number of red blood cells that do not burst equals;

          0.40/2 x 100% = 20%
