The structure of DNA is double helix which looks like twisted ladder. The sides of the DNA molecule, the rails of the ladder are composed of alternate phosphate and sugar molecules.
Answer: A
Fungi are heterotrophic (decomposers) and are often mistaken as a plant because its rooted in the soil. But what also makes them different from plants is that fungi don't do photosynthesis and not all fungi are multicellular.
Answer:
Asexual reproduction can be described as a process in which daughter cells are produced which are 100% identical to the parent cells. Unlike the process of sexual reproduction, no recombination occurs in asexual reproduction. Hence, no variability is produced when organisms reproduce by this method.
<u><em>As there will be lack of variability in asexual reproduction, the whole of the particular species might become endangered or extinct due to a disease or due to other factors like pests.</em></u>

The answer is C.
Viruses cannot reproduce without a host. Viruses do not eat selves to provide energy for their reproduction.
Viruses do not reproduce outside of cells nor do they create harmful chemicals on their own.
1. Contraction of the iliacus and psoas major produces flexion of the hip joint
2. quadriceps femoris muscle group
3. A combination of gluteal and thigh muscles also adduct, abduct, and rotate the thigh and lower leg. The tensor fascia latae is a thick, squarish muscle in the superior aspect of the lateral thigh. It acts as a synergist of the gluteus medius and iliopsoas in flexing and abducting the thigh.
4. triceps brachii
5. The major muscle that laterally flexes and rotates the head is the sternocleidomastoid
6. Rectus abdominis
7. The external obliques are the outermost abdominal muscles. They are also key participants in spinal flexion and the compression of the viscera. Individually, they act alongside the internal obliques in lateral flexion and spinal rotation.
8. abdominal external oblique muscle
9. external intercostal muscles
