Answer:
All living things are made of cells.
Explanation:
All living things are made of cells is a common attribute of all living things. So the correct option is A.
What are living organisms?
Any organism or sentient being that has signs of life or is alive is referred to as a living creature. The basic traits include having a structured structure, requiring energy, reacting to stimuli and changing their surroundings, and having the ability to reproduce, grow, move, metabolize, and die.
The three Domains that make up the current classification of living things are (Eu)Bacteria (real bacteria), Archaea (archaebacteria), and Eucarya (eukaryotes).
Abiogenesis is the name for the natural process by which life sprang from non-living elements, and is referred to as the origin of life. The cause of this is still up for dispute among experts. There has never been agreement about the origin of life on Earth.
Therefore the correct option is A.

Complete the sentences to describe the structure of DNA. The shape of the DNA molecule is called a double . The backbone of DNA is made of molecules and phosphate molecules. The "rungs" of DNA are made of .
Answer:
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.
DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.
The National Human Genome Research Institute (NHGRI), a part of the National Institutes of Health (NIH), provides a fact sheet Deoxyribonucleic Acid (DNA) that gives an introduction to this molecule.
StatedClearly offers a video introduction to DNA and how it works.

The shape of the DNA molecule is called a double helix. The backbone of DNA is made of sugar molecules and phosphate molecules. The "rungs" of DNA are made of four nitrogen bases that are adenine, thymine, guanine, cytosine.
What is DNA ?The molecule found inside cells that contain the genetic information necessary for an organism's development and function. DNA molecules enable this information to be passed down from generation to generation.
DNA is made up of a series of molecules known as nucleotides. A nitrogen base, a sugar group, and a phosphate group are all present in each nucleotide. Adenine (A), Thymine (T), Guanine (G), and Cytosine (C) are the four nitrogen bases that can be found in DNA (C). There are billions of DNA bases in human DNA.
It stores instructions for the production of larger molecules known as proteins. These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes.
Thus, chromosomes are composed of thousands of shorter DNA segments known as genes.
