A relatively small organelle that contains enzymes that oxidize organic substances.- Peroxisomes.
Small membrane-bound organelles called peroxisomes oxidize organic compounds using molecular oxygen. They have a few enzymes that can either make or break down hydrogen peroxide.Peroxisomes are organelles that include a variety of oxidative processes and are crucial for metabolism, the detoxification of reactive oxygen species, and signaling. Fatty acid -oxidation is one of the oxidative mechanisms housed in peroxisomes and is involved in embryogenesis, seedling growth, and stomatal opening. Hydrogen peroxide is created by the oxidation of organic molecules in peroxisomes. This is immediately transformed into water and oxygen. Cholesterol and phospholipids, which are present in brain and heart tissue, are made by peroxisomes.learn more about peroxisomes here: https://brainly.com/question/12146953

In mammals, why is aneuploidy of the x chromosome more often viable than aneuploidy of the autosomes?
In mammals, is aneuploidy of the x chromosome more often viable than aneuploidy of the autosomes is only one X chromosome remains fully functional in mammalian cells.
Many or all genes on additional X chromosomes are silenced early during development.
Aneuploidy is the condition in which the chromosomes and the number of it are missing that is either one chromosome can be missed or more than one which can lead to abnormalities in the body and malfunctioning in the expression of characters and can also lead to any chromosome number that is not the exact multiple of haploid number which in humans is 23 and its paired form has 46 chromosomes so whenever there is a loss in one chromosomes or addition of one chromosome it can lead to different syndromes like down syndrome, knilfeltners syndrome, turners syndrome and many more and it can be the main cause of miscarriages during pregnancy as well and in mammals aneuploidy of x chromosome is more viable because only one X chromosome remains fully functional in mammalian cells.
Many or all genes on additional X chromosomes are silenced early during development. In females there are two x chromosomes so even the other is silenced the other one is functional and in the same way in males the x chromosomes remains functional that is why aneuploidy affects are seen on x chromosomes.

Answer: Oxygen
Explanation:
During cellular respiration, the cell uses oxygen to break down sugar
The element essential in helping our bodies break down substances found in our food is hydrogen. The correct option is A.
Where is the hydrogen comes from?Only six elements make up the majority of the human body: oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus.
Hydrogen is a key component in aiding our bodies in dissolving chemicals contained in meals.
Water, enzymes, and acids that aid in the breakdown of food molecules into smaller, easier-to-digest components that can be absorbed by our cells are just a few of the vital substances in our bodies that contain hydrogen as a fundamental ingredient.
Other significant physiological processes that utilize hydrogen include the creation of ATP, the body's principal source of energy, and pH balance maintenance.

Functions of neurons supported by glial cells, which provide support and also help increase action potential, hence option c is correct.
What are glial cells?Neurons are the basic functional units of the nervous system, and they create electrical impulses referred to as action potentials, which allow them to transmit data swiftly over large distances.
Glia is also essential for nervous system function, although they primarily serve to support neurons. Despite the complex nature of the nervous system, the nervous system consists of only two main types of nerve cells: neurons and glial cells.
Glial cells clearly provide "support" both for cells such as neurons and structures such as blood vessels, they can also function to increase action potential conduction.

The tissue that always has a free surface exposed to the internal or external environment is epithelia.
A group of cells that perform similar functions and have a similar structure can be referred to as a tissue. Tissues are of four types- epithelial, connective, muscle, and nervous tissue. Epithelial tissue acts as a protective sheath, connective tissue joins other tissues and keeps them in place, muscle tissues help in voluntary and involuntary movements, and nerve tissues carry signals to and from various parts of the body. Epithelial tissue are remain exposed to the internal or external environment as they protect the interior of the tissues from the damage caused by such environments.
The epithelium is an animal tissue that covers the surface of organs, blood vessels, and cavities of the internal organs. It covers the body surfaces that are exposed to the external environment and lines the body cavities exposed to the internal environment.

They both contain carbon, but only carbohydrates contain oxygen
They both contain carbon, but only nucleic acids contain phosphorous.
They both contain carbon but nucleic acids contain phosphorus. So, the correct option is D.
What are nucleic acids and carbohydrates?
Nucleic acid is a naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid, sugars, and a mixture of organic bases (purines and pyrimidines).
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Carbohydrate is any member of a large and diverse family of naturally occurring organic molecules that include sugars, starch, and cellulose.
Monosaccharides (simple sugars such as glucose and fructose), disaccharides (2-unit sugars such as sucrose and lactose), oligosaccharides (3-10 or more sugars), and polysaccharides are the most prevalent types (large molecules with up to 10,000 monosaccharide units, including cellulose, starch, and glycogen).
