Which of these changes to the cell would cause the greatest reduction in the activity of the catalase?
CHOICES:
#1 a return of pH to the normal range
#2 A decrease in the concentration of hydrogen and oxygen
#3 an increase in the concentration of hydrogen peroxide
#4 an increase or decrease in PH beyond normal range
Answers
Answer:
#3 an increase in the concentration of hydrogen peroxide.
Explanation:
The changes to the cell that causes the greatest reduction in the activity of the catalase would be - #3 an increase in the concentration of hydrogen peroxide.
Catalase enzyme is present in both plant and animal cells. The catalase is mainly found in aerobic organisms. The substrate for the enzyme is hydrogen peroxide which is broken down into oxygen and water.
The hydrogen peroxide is harmful to the cell and very reactive. Its buildup can kill the cellto breakdown the hydrogen peroxide, the catalase enzyme catalyzes it and convert it into water and oxygenincrease of the hydrogen peroxide leads to a reduction in the activity of the catalase.A single molecule of the catalase can break down 40 million molecules of hydrogen peroxide per minute.Thus, the correct answer is - #3 an increase in the concentration of hydrogen peroxide.

Why is the earth's gravity stronger than the moon's gravity? A:The moon is so far away from earth. B:The earth is more massive than the moon C:The moon has no mass. D:The earth has a larger volume than the moon.
Answers
Answer:
A and B
Explanation:
Gravity relies on both mass and distance
The reason the earth's gravity stronger than the moon's gravity is B. The earth is more massive than the moon
How is the earth gravity stronger ?Gravity is a force that attracts two objects with mass towards each other. The more mass an object has, the stronger its gravitational pull.
The distance between two objects also affects the strength of gravity. However, the distance between the Earth and the Moon is not large enough to significantly weaken the Earth's gravitational pull.
The Earth has a mass of about 5.972 × 10^24 kilograms, while the Moon has a mass of about 7.347 × 10^22 kilograms. This means that the Earth's gravity is about 6 times stronger than the Moon's gravity.

B.) cooled slowly
C.) found deep underground
D.) different easily observed minerals

Answer:

Explanation:

Fine texture describes an extrusive rock. thus option A is correct
What is rock cycle ?Rocks are formed naturally and it is the non-living earth made by collection of mineral grains held together in a firm, it can be tiny or big as well and can be easily identified with their texture.
The Rock cycle is a continuous process through where old rocks are transformed into new rock by a process of cool down of molten magma, when it solidifies become igneous rock.
In a rock cycle, when the break down of these igneous rocks occur small particles that are transported and deposited to form sedimentary rocks, When the igneous and sedimentary rocks heated up and under the pressure they change into metamorphic rocks.
The metamorphic rocks which are subjected under great heat and pressure melt down to form molten magma which again can cool down and solidify into igneous rocks

If you have a 20% sugar solution and a 45% sugar solution how does the 20%
solution compare to the 45% solution?
Answers
Answer:
It is 25% less
Explanation:
That is all i can say
A close comparison of the 20% solution to the 45% solution shows that the 20% solution is actually less than 50% of the 45% solution.
Arithmetically, you discover that the 20% solution is 25% or 0.25 (45% - 20%) less than the 45% solution.Comparatively, you can compute that the 20% solution actually represents 44.4% or 0.444 of the 45% solution (20% x 45%). The same result can be obtained by first dividing 20% by 45% and then multiplying the resulting dividend by 100.Thus, the result of the comparison shows that there is more sugar in the 45% solution than there is in the 20% sugar solution.

A
Explanation:
i hope thia helps and sorry if yoy get it wrong! ^w^
People with diabetes have a hard time keeping a balance blood-glucose level because they don’t synthesize any insulin hormone, to help shuttle glucose into cells when there is a need. Thus, the correct option is A.
What is Diabetes?Diabetes may be defined as a type of metabolic disease that is characterized by elevated levels of blood glucose (or blood sugar).
The body of individuals with this type of chronic disease does not regulate the amount of glucose (a type of sugar) in the blood and the kidneys construct a large amount of urine.
This whole abnormal circumstance takes place when the body does not synthesize enough insulin hormone that helps in the regulation of elevated blood glucose levels by transforming it into other forms such as glycogen.
Therefore, people with diabetes have a hard time keeping a balance blood-glucose level because they don’t synthesize any insulin hormone, to help shuttle glucose into cells when there is a need. Thus, the correct option is A.

what is Gravitational force ?A gravitational force is defined as an attractive force which is exerted by a massive body on the massive body. So our body always tries to pull other body towards itself due to this gravitational force.
gravitational force is a force exerted by earth on other objects and can be represented as F=mg
F is the force of gravity, G is the gravitational constant of the universe and it is always the same number, M is the mass of one object, m is the mass of the other object (measured in kilograms, kg), r can be the distance those objects are apart (measured in meters, m)
This force can also be called as Newton's Universal Law of Gravitation And the object that are really far apart from each other don't pull on each other noticeably either.

The "calico" pattern of coat coloration in female cats is a result of:__________
a. fragile X syndrome
b. x chromosome inactivation
c. unequal crossing over
d. endoreduplication
e. Turner syndrome
Answers
Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.
