Answer:
The answer is B: Active Transport
Explanation: Because energy is required to move the sodium and potassium ions against the concentration gradient. Sodium ions are actively transported from the inside of the cell to the outside of the cell, even though there is a higher concentration of sodium ions on the outside.
1. The answer is; soil. When rock weathers, it disintegrates into small and smaller particles. When these fine rocks particles combine with organic matter from living organisms, they make soil. The mineral component of the soil is therefore similar to that of the parent rock from which it came from.
2. Chemical weathering involves the reaction of the rock mineral with ‘chemicals’ or other compounds. These may include reaction with organic acids or acidic rainwater. Due to the chemical reaction, the rock chemical composition changes and the physical appearance may also look different.
3. The answer is limestone rocks. They are made of carbon-carbonate minerals. Carbon carbonate is easily dissolved by acids include slightly acidic rainwater/ precipitation.
CO2 + H2O → H2CO3 (carbon dioxide + water → carbonic acid)
H2CO3 + CaCO3 → Ca(HCO3)2 (carbonic acid + calcium carbonate → calcium bicarbonate)
4. Weathering of rocks is slower in cold regions than dry regions. This is because cold places do not encourage chemical weathering. Chemical weathering requires higher temperatures to increase the energies of the chemical atoms so that they react fast.
Answer:
Because they all have a different purpose
Explanation:
The epidermis provides a waterproof barrier and creates our skin tone.
The dermis, the middke layer of skin , contains tough connective tissue, hair follicles, and sweat glands.
The hypodermis is made of fat and connective tissue.
Answer:
Anchoveta feed on large zooplankton whereas sardines feed mainly on phytoplankton. Use this information to suggest why sardine numbers are less
likely to collapse during an El Niño event?
Reason why sardine are less likely to collapse during an El Nino event is as a result of sardine survival is neither dependent on zooplankton nor anchoveta rather sardine is dependent on phytoplankton which is not scarce
