Question:What is one difference between the theory of continental drift and the one theory of plate tectonics
Answer/Explanation: Continental drift is the hypothesis that states that the continents once formed a single landmass(Pangaea) broke up and drifted to their present locations.Sea-floor spreading the process by which new oceanic lithosphere(sea floor) forms as magma rises to Earth's surface and solidifies at a mid-ocean ridge.
1. Rock is buried deep under Earths surface. 2. Rock melts due to high temperature. 3. Magma is forced out of Earth's surface during volcanic eruption. 4. Magma cools and crystallizes. Rock from underneath the ground has to heat up and be pressurized first. After enough pressure and heat are applied the volcano will erupt. Extrusive igneous rocks are formed when lava cools on Earth's surface above ground.
Old existing cells.......
The immune system is spread throughout the body and involves many types of cells, organs, proteins, and tissues. Crucially, it can distinguish our tissue from foreign tissue — self from non-self. Dead and faulty cells are also recognized and cleared away by the immune system.
If the immune system encounters a pathogen, for instance, a bacterium, virus, or parasite, it mounts a so-called immune response. Later, we will explain how this works, but first, we will introduce some of the main characters in the immune system.
Answer:
Slow-twitch
Explanation:
Red meat is rich in slow-twitch muscle fibers. The slow-twitch muscle fibers are rich in myoglobin and blood capillaries. They also have many large mitochondria to generate ATP by aerobic respiration.
These fibers are slow-twitch fibers as the ATPase in myosin head carries out the hydrolysis of ATP at a slower rate causing a slower contraction cycle.
Slow-twitch fibers appear red due to a large amount of myoglobin and a rich network of blood vessels. They are capable of prolonged contractions and are fatigue resistant.
