The study of the properties and changes in matter and their relation to energy
a. Physical Chemistry
b. Biochemistry
c. Organic Chemistry
d. Inorganic Chemistry

Answers

Organic Chemistry

Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds. Most organic compounds contain carbon and hydrogen, but they may also include any number of other elements (e.g., nitrogen, oxygen, halogens, phosphorus, silicon, sulfur).

The study of the characteristics and changes of matter, as well as the interactions between matter and energy, is the focus of the field of chemistry known as physical chemistry. Therefore, the correct option is A.

It integrates ideas from physics and chemistry to understand the molecular behavior of molecules and atoms. Thermodynamics, kinetics, quantum mechanics, spectroscopy, and statistical mechanics are among the subjects studied by physical chemists.

Their work advances many disciplines, including biology, chemical engineering and materials science. By understanding the fundamental ideas of physical chemistry, scientists can create new materials, predict and explain chemical reactions, and understand the subtleties of molecular interactions in many systems.

Therefore, the correct option is A.

what will happen if phase changes didn't exist?​

Answers

Answer:

Matter can exist in one of several different states, including a gas, liquid, or solid state. The amount of energy in molecules of matter determines the state of matter.

A gas is a state of matter in which atoms or molecules have enough energy to move freely. The molecules come into contact with one another only when they randomly collide.

A liquid is a state of matter in which atoms or molecules are constantly in contact but have enough energy to keep changing positions relative to one another.

A solid is a state of matter in which atoms or molecules do not have enough energy to move. They are constantly in contact and in fixed positions relative to one another.

Indigestible residues along with some of the non-reabsorbed secretions of digestive organs, undergo ____________ where the fluids are removed and a remaining solid is created.

Answers

The digestive system is involved in the breakdown of molecules to yield energy. As food passes along the digestive gut, it undergoes various processes in its breakdown.

Indigestible residues along with some of the non-reabsorbed secretions of digestive organs, undergo Compaction where the fluids are removed and a remaining solid is created.

Compaction during digestion occurs in the large intestines. This occurs wherein water is removed from the indigestible residues and reabsorbed enabling the compacting of these waste materials. Afterwards, a solid-waste material is produced.

Which option(s) correctly describes chromosomes?
Chromosomes consist of tightly coiled DNA wrapped around proteins called histones
Each chromosome has one gene
Chromosome pairs contain completely different genes
Most human cells have two copies of each chromosome - one from each parent.

Answers

Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.

One parent has red, axial flowers and the other has white, terminal flowers; all F1 Individuals have red, axial flowers.
