Answer:
A chromosome mutation is an unpredictable change that occurs in a chromosome. These changes are most often brought on by problems that occur during meiosis (division process of gametes) or by mutagens (chemicals, radiation, etc.).
Explanation:
Brainliest please?
Answer:
1) Different types of chromosome mutations can originate in the germinal cells.
2) Chromosome mutations are alterations occurring in chromosomes that typically result from errors during nuclear division or from mutagens. ... Abnormal chromosome numbers result from nondisjunction, or the failure of chromosomes to separate correctly during cell division.

If a cell with little hydrogen peroxide begins producing a large amount, what will happen to the rate at which the hydrogen peroxide is broken down
Answer:
Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product. The result is an increasing amount of foam produced in your cup as you increase the amount of H2O2 in your reaction.

A) gold
B) oxygen
C) neon
D) water
The term that would be modeled by small particles made up of atoms of two kinds of elements is water. The correct option is D).
What are elements?Chemical elements are the pure forms of substance that are present in the art surface or crust. There are 118 elements present in a periodic table there, arranged in the raising of their atomic number.
Water is a compound that is made from two elements, Oxygen, and hydrogen. There are two molecules of hydrogen and 1 molecule of oxygen in the water.
All others are elements like gold, oxygen, and neon. They are present in the periodic table they are pure substances, and they are single elements. They're not made up of 2 atoms or two kinds of elements.
Water is present on earth in three states liquid solid gas forms. It is the most important compound on the earth, all living organisms are made up of 90%.
Thus, the correct option is D). water.

(50 points) Think about the renewing of cells in a human body. What would happen if new cells stopped forming when we reached maturity while old cells never died off? Then consider what would happen if new cells continued to form while old cells never died off?
Answer:
We would gradually decay, and it would be horrific, and if new cells contiued to form it would also be pretty horrific
Explanation:
If we reached maturity while old cells never died off , this would heighten the risk for genetic and hereditary disorders, and new cells are not formed through mitosis, and are unable to replace inefficient or cells with damages, whether it not be to the DNA or other organelles.This would cause a significant decline of production in our body, and would also cause cells such as your skin cells, to be at a heightened risk of genetic and hereditary disorders and diseases such as cancers and melanomas
If our cells continued to form while old ones never died off, if would also be very inefficient for our bodies, as the amount of energy and ATP required to support an ever-growing cell population of that size would leave us wanting to eat more and more each day to fufill our daily metabolic processes, leaving us skinny and weak.This would also cause a loss of some function in some areas, because some areas require more energy than others, such as your pulmonary and cardiovascular system, and could result in wasting of muscle tissure, as they would not be getting the nutrients needed
If new cells would stop forming once maturity is reached, and old cells would never die. Genetic disorders would be more common, cells with damage would not be replaced, hereditary disorders would also be more common, such as cancers and others. If new cells continued to form and old cells would never die off, the amount of energy that is required to normally support us would leave us wanting more food each day to achieve our metabolic process.
