In Unicellular-reproduce organisms while Multicellular-repairs dead or damaged cells. They both help develop and grow. in the multicellular this organism is made up of 2 or more cell they can be made up to trillion if cells, it is much more complex than the unicellular. They reproduce asexually and the cells cannot live outside the organism, they perform specialized functions an example: nerves.

Which of the following most directly influences a measurable outcome in an experiment. An independent variable A variable hypoth

Reika [66]

Answer:

An independent variable

Explanation:

An experiment consists of two variables viz: independent and dependent variable. Independent variable is the variable that the experimenter controls in order to influence or effect a change in the measurable variable called dependent variable. As the name suggests, the dependent variable is dependent on the independent variable.

For example, a scientist is trying to conduct an experiment on how the caffeine level in different types of drink affects the time of sleep in individuals. The independent variable in this experiment is the TYPE OF DRINKS because it is the variable controlled by the experimenter in order to influence the time of sleep (measurable outcome).

How does carbonic anhydrase change the reaction between carbon dioxide and water?

Natalka [10]

It catalyzes the reaction by making it fast (both forward and reverse reactions).

Naturally, the reaction between CO2 and H2O is very slow in the formation of carbonic acid. However, in the blood, due to the presence of the enzyme, the reaction is much rapid by millions of factors. This is because the enzyme reduces the activation energy of the reactants. The enzyme is important in respiration of cells and in pH regulation,

REY [17]

Answer:

Charles Darwin’s study of evolution predicts that genetic evidence would show that all organisms share a common ancestor.

Option: (B)

Explanation:

Through his "theory of evolution", Darwin found that the species exist and new species form based on natural selection.
He studied the animals and birds in Galapagos island for his evolution theory.

The four key points of Darwin's Theory of Evolution:

individuals of any species are not identical;

genes are passed from one 'generation' to another;

more offspring are born than can survive;

only the 'survivors of the competition' for the resources will reproduce.
