Mass movement, which is sometimes called <em>waste movement</em> or <em>slope movement, </em>is defined as the large movement of rock, soil and debris downward due to the force of gravity.
<h3>Factors affecting mass movement
</h3>
1. Slope
- Gravity provides the energy to move the materials.
- Rapid movements (e.g. landslide, slumping) etc.
2. Water
- Rainwater acts as a lubricant to weathered materials.
- Rainwater adds weight to weathered materials.
3. Rock structure
- Joints dipping downslope usually assists landslides, rockfalls, rockslide etc
4. Vegetation
- Lack of vegetation cover to hold the loose particles.
5. Vibrations
- Earthquakes.
- Construction processes and mining operations.
Answer:
The answer is letter C
Explanation:
The evolutionary mechanism most likely responsible for the difference between the two populations is natural selection.
Answer: The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.
Explanation:
Answer:RNA polymerase – makes a molecule of RNA from an RNA template
Explanation: RNA polymerase is an enzyme that catalyzes the copying of a DNA sequence into an RNA sequence during transcription. RNA polymerase uses a DNA template for the synthesis of an RNA strand. RNA polymerase is also called DNA-dependent RNA polymerase. During transcription, DNA helicase unwinds the double helix of the DNA while the RNA polymerase catalyzes the synthesis of an RNA strand from the DNA.
Sweat is used for thermoregulation. As sweat is released onto the surface of the epidermis, heat from the body is conducted into the water. Water is a better conductor of heat than air is. As the sweat evaporates, the heat from the body dissipates into the environment.
