Answer:

Enzyme catalase is affected by high temperatures

Explanation:

Enzymes are organic catalysts which are protein in nature therefore they are sensitive to changes in temperature. Most enzymes have an optimum range of temperature between 35-40°c.

As temperature is increased, the optimum temperature is reached where the rate of reaction is maximum. When beef liver is boiled, hydrogen peroxide is not broken down because higher temperatures denature enzymes making them non effective.

Higher on the outside,

because the potatoes feel heavier, that means they must contain more water, which also means they had to have sucked in some water or had more water in them to begin with.

concentration usually likes to go from high to low in order to balance things out, so the only way water could enter the cells through osmosis would be if the concentration of water were higher on the outside of the cells

qaws [65]

Answer:

Based on the scenario being described within the question it can be said that the most likely reason for this misconception would be that the spiral galaxies looked like clouds of gas and dust through telescopes because of their distance from Earth.

sergiy2304 [10]

Answer:

This question is incomplete, the complete part is asking to identify the variables of the experimental statement i.e. dependent and the independent variables.

Independent variable: different amounts of time light is on

Dependent variable: Number of eggs laid by chicken

Explanation:

In a scientific experiment, variables, which are factors that can be altered, are used. These variables are independent and dependent variables.

An independent variable is that variable that is subject to manipulation or control by the experimenter in order to bring about a change in the dependent variable. For this experiment, the independent variable is the DIFFERENT AMOUNT OF TIME LIGHT IS ON.

On the other hand, a variable is said to be dependent if it is the measurable or responding variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the NUMBER OF EGGS LAID BY CHICKENS. The number of eggs laid (dependent variable) is dependent on the amount of time light is on (independent variable).
