The answer is A) food web. B is not actually a thing, and C and D are very different vocab words.
Answer:
Arteries have thick walls composed of three distinct layers (tunica) Veins have thin walls but typically have wider lumen (lumen size may vary depending on specific artery or vein) Capillaries are very small and will not be easily detected under the same magnification as arteries and veins.

In eukaryotic cells cellular structure is composed of a neatly packaged DNA molecule histone octamer.
In eukaryotes, however, genetic material is housed inside the nucleus and tightly packaged into linear chromosomes. Chromosomes are made of a DNA protein complex called chromatin this is prepared into subunits referred to as nucleosomes. A chromosome is made up of proteins and DNA organized into genes. each cell usually incorporates 23 pairs of chromosomes.
The records in DNA is stored as a code made from four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA includes about bases, and greater than 99 percentage of those bases are the identical in every person.
DNA is tightly packed up to healthy inside the nucleus of each cell. As proven within the animation, a DNA molecule wraps round histone proteins to shape tight loops known as nucleosomes. these nucleosomes coil and stack collectively to shape fibers referred to as chromatin.
