Answer:
False
Explanation:
Stem cells are different type of cells in human body that can develop into different other body cells like muscles cells or brain cells and they gave the capability to renew themselves through mitotic cell division.
Stem cells are not lost in childhood but can be use to treat diseases or infection, it can be use to grow new cells and replace damaged body cells.
The answer is catalysts. Catalysts speed up the rate of a <span>reaction</span> without<span> </span>getting consumed in the process. Catalysts,
in <span>this</span> case, enzymes act by reducing the
activation energy or changing the reaction mechanism (such as foregoing some transition
states). A popular enzyme is a <span>carbonic</span>
anhydrase that <span>catalyzes</span> the formation of
carbonic acid in the <span>blood</span> plasma (<span>from</span> carbon <span>dioxide</span>
and water), a critical function in regulating blood pH.

Explanation:
Answer:
The answer is B: They can be passed on to offspring.
Explanation:
According to Lamarckism, environment keeps changing and during the course any structure which is more in use increases in size and is inherited by the offspring whereas any structure which is not is use diminishes and is lost in the offspring. The most famous example is the neck length of giraffe. When the vegetation was not available at the ground level, giraffe started stretching its neck to feed on leaves high on trees. The led to increase in the length of neck and this feature passed on to the offspring.
Similarly a person with large muscles (like in wrestlers) will inherit the features to the offspring.
Lamarckism was later disproved by Darwin's theory of natural selection.
Answer:
Different temperatures in her backyard
Explanation:
The independent variable would be <u>the different temperatures in Pinky's backyard.</u>
The independent variable is a variable whose value is not affected by another variable during research. It is a variable that directly affects the actual variable that is measured - the dependent variable. The independent variable is usually varied in order to see the kind of effect it will produce on the dependent variable.
<em>In the case of Pinky, the different temperature at the backyard affects the number of cricket chirps. Hence, the temperature is considered the independent variable while the number of cricket chirp is considered the dependent variable.</em>
