Answer: Gas exchange that occurs at the level of the tissues is called internal respiration. The correct option is C.
Explanation:
Respiration a process in living organisms involves the production of energy, with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances. There are about four types of respiration and these includes:
- Ventilation
- External respiration
- Internal respiration
- cellular respiration
In respiration, passive movement of gases by diffusion occurs between cell surfaces in a process called gas exchange. Without this process, oxygen cannot be taken into the cells and carbondioxide released. I hope this helps. Thanks.
Initiation, Elongation, and Termination
or
1. The Double Helix unzips (into two halves) and the enzymes break apart of the hydrogen bonds between the bases.
2. DNA polymerase moves along the strands and adds free floating nucleotides to the nitrogen bases accorinding to base pairing rules
3. Two new double helixes are formed
They had no natural predators, so they spread quickly and ate the farmers crops and also made the bilby an endangered species.
Answer:
A. Galaxies
Explanation:
Galaxy cluster is known to contains 50 to 1000 galaxies, having a total mass between 100 trillion and 1 quadrillion solar masses, crossing across a distance of 30 million light years.
The word galaxy is derived from the Greek galaxias which means milky, a reference to the Milky Way. Galaxies range in size from the smallest of it with just a few hundred million stars to giants with one hundred trillion stars, with each rotating/orbiting its galaxy's center of mass.
