Answer:

The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.

Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.

Answer: During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

Answer:

the waste products are carbon dioxide and water

Answer:

I would need the statements to answer that. however prokaryotic cells are plant cells and eukaryotic cells are animal cells

Answer:

They are typically smaller than eukaryotic cells. The DNA of a prokaryotic cell is contained in the nucleoid. There are several ways in which prokaryotic cells are different from eukaryotic cells. Firstly, they are generally smaller in size, their organelles are not membrane bound, and they have no nucleus. They, however, share commonalities with eukaryotic cells including the presence of a bilipid plasma membrane, presence of ribosomes and DNA.

The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.

Explanation:

Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.

Answer:

Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses

Answer:

greenhouse gasses get trapped in the atmosphere and contribute to global warming

Answer: The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere.

Eukaryotic cells are believed to be evolved more recently than prokaryotic cells.

Explanation:

The statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells

Cells are fundamental units and are mainly two types eukaryotic cells and prokaryotic. There are various structural and functional differences and similarities found in them.  

Prokaryotes and eukaryotic cells have the following difference:  

Thus, the statement about eukaryotic cells is NOT true - Eukaryotic cells are usually smaller than prokaryotic cells

Answer: All substances are built from

compound

oxygen

Explanation:

All substances are built from atoms as atoms are the basic building blocks of matter and are the smallest units of a chemical element. The correct option is D.

Atoms form the basis of all compounds. The fundamental building blocks of matter, atoms are the smallest units of a chemical element that nonetheless retain that element's chemical characteristics.

Atoms from various elements combine chemically to produce compounds, however compounds themselves are not the basic building blocks.

Although oxygen is an element that is present in several substances, it is untrue to say that oxygen is the primary component of all substances.

Although metals are a specific kind of element, not all substances are made of metals. Thus, the most correct response is that all substances are composed of atoms.

Thus, the correct option is D.

As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.

These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder.  The type of sugar that is used in a DNA helix is called deoxyribose.

Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.

Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.

Therefore, A person with a low number of white blood cells could have difficulty in fighting infections and A decrease in the number of lymphoid stem cells could result in a decrease in red blood cell.

Explanation:

Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.

If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.
