Part 1: Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continuous circulation pattern.
Part 2: The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.

Explanation:

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

Sergio039 [100]

Answer:

Cloning may be defined as the process by which the genetically identified individual of the organism can be created artifically or naturally. Aseual reproduction results in the formation of clone.

The microsatellite analysis is used to prove that snuppy is a clone. Microsatellites are the highly variable DNA sequences repeats that has variable loci and considered at population level. The two alleles are possible for the one microsatellite locus. After comparing the alleles it has been found that snuppy has exactly the same genetic material as the surrogate mother, afghan. This completely determines that snuppy is a clone of afgan.

Novosadov [1.4K]

Answer: b. Webbed-toed mice survived better and reproduced more than mice without webbed toes.

Explanation:

Natural selection is a phenomenon that suggests that organisms that have a better structural and morphological advantage over the others have better chances of survival over the others.

The webbed toed mice have a survival advantage over the without the webbed toes because this can help the webbed toed mice to swim. The webbed toed trait will be beneficial and passed on to the next generation of the mice and the webbed toed mice will reproduce more than the mice without webbed toes.
