Which statement correctly describes a chemical reaction?
A. Reactants come out of a reaction.
B. Energy is always released.
C. Bonds between atoms break and reform.
D. Products go into a reaction.

Answers

Answer 1

Answer:

C). Bonds between atoms break and reform.

Explanation:

A Chemical reaction is defined as the process in which the substances(two or more) interact and form new substances by rearranging the atom structure of the substances. This process primarily consists of two steps i.e. breaking of chemical bonds that exist between the atoms in the original substances and the formation of new bonds to produce the new substance. Thus, the bonds break and reform. Hence, option C is the correct answer.

Are microscopic and macroscopic ecosystems affected by limiting factors differently? Explain.​

Answers

Answer:

No.

Explanation:

No, the microscopic and macroscopic ecosystems can't affected by limiting factors differently because both required the same factors for their survival and growth. The factors required by every organism in both microscopic and macroscopic ecosystems such as food, water, habitat, and reproduction. If these factors are limited then the population of the organisms will be lower. So both affected the same due to limiting factors.

a.) centrosome
b.) chromosome
c.) centromere
d.) vacuole
e.) centriole

Answers

Answer:

the closest answer is b.

Explanation:

The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA.

Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure. Thus, option B is correct.

What is the role of chromosomes?

DNA, the cell's genetic material, is kept in the nucleus. In the nucleus, DNA is often found wrapped up and linked to a variety of histone proteins in a structure called chromatin that is loosely contained.

Chromatin coils tightly and condenses to produce chromosomes just before a cell divides. A DNA molecule called a chromosome is where an organism's genetic code is located.

When a cell is not dividing, chromosomes cannot be seen in the nucleus, not even under a microscope.

Therefore, a chromosome is the structure that contains the DNA of the cell.

Which of the following is a chemical property of iron?
A. Iron corrodes in moist air.
B. Iron is soft when pure.
C. Iron melts at 1808 K.
D. Iron's density = 7.874 g/cm3

Answers

Answer:

A

Explanation:

Iron corrodes in moist air. When iron gets exposed to air, it reacts with oxygen molecules to form rust. Rust degrades the quality of iron. Therefore, methods of protection from rusting like, Barf's protection, Sacrificial protection etc. are carried out.

Iron corrodes in moist air is a chemical property of iron. Hence the correct option is A.

A chemical property of iron is its ability to corrode in moist air. Corrosion is a chemical reaction that occurs when iron reacts with oxygen and moisture in the air, resulting in the formation of iron oxide, commonly known as rust. This chemical property of iron is due to its reactivity with oxygen and can lead to the degradation and weakening of iron-based materials over time.

Corrosion is a chemical process that involves the reaction of a metal with its environment, typically in the presence of moisture or oxygen. In the case of iron, when it comes into contact with moist air, it undergoes a chemical reaction known as oxidation. This reaction causes the formation of iron oxide, commonly known as rust.

The corrosion process begins when iron reacts with oxygen in the air, a process called oxidation. This reaction leads to the formation of iron(III) oxide, which is commonly seen as the reddish-brown coating known as rust. The presence of moisture accelerates the corrosion process by providing the necessary medium for the reaction to occur.

Hence the correct option is A.

When a catalyst is present in a biochemical reaction, what is not expected is that the reaction requires more energy than normal (option b).

Explanation:

A catalyst is a substance used to facilitate a chemical reaction, decreasing the reaction time. Unlike a reagent, the catalyst retains the same amount of mass at the end of the reaction.

In a biochemical reaction, the use of a catalyst not only accelerates the reaction, but also decreases the amount of energy required by the process. An example of a biological catalyst is enzymes, specialized proteins that facilitate metabolic reactions.

The other options can be expected with the use of a catalyst, due to:

    a. One of the functions of the catalyst is to decrease the amount of energy needed in a reaction.

    c. Catalysts are substrate specific.

    d. Catalysts work in a specific pH range.
