Answer:
7 followed by 27 zeros
Explanation:
The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.
The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.
In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.
Answer:
Mutations are important to the evolution of a species because is creates new DNA for a certain gene, creating a new allele.

Gown
The nurse would put on the gown first when utilizing personal protective equipment (PPE). The nurse would then put on the mask, goggles, and gloves.

- Fasten around the waist and neck.
STEP 2: SHOE COVERS
- Layer shoes with shoe covers on top.
STEP 3: GLOVES
- Apply the first set of gloves and inspect them for tears.
- Thumb hole made in lab coat
- Thumb through opening in lab coat after pulling it over the hand
- Put on a second set of gloves (extend to cover wrist)
STEP 4: MASK OR RESPIRATOR
- As you cup the respirator in your hands, place the nosepiece there.
- With the nosepiece up, place the respirator under your chin. Pull the top strap over your head, putting it at the back of your head.

Answer:
Option D
Explanation:
Diagram is attached.
Capsid protein is a form of structural protein which usually forms part of a complex which later produces protective shell around the nucleic acid in a virus. It is also referred to as coat protein or head protein.
Capsid acts as a distinguishing feature for identifying an integrated viral genome, plasmids and other genetic material of viruses. In fact, viruses are termed as organisms that encode capsid proteins.
Hence, option D is correct
Answer:
Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species. ... An example of macroevolution is the evolution of a new species.
