All of the above are made using wood.
Answer: Natural selection is the driving force to explain the mechanisms of evolution.
Explanation:
◼In a given population Organisms usually produce more offspring than what the environment can support.
◼ VARIATION, is driving force for the manifestation of sustainable inheritable characteristics from parents in a given population.
◼ Organisms, who acquired certain characteristics from variation; tend to survive than others, and therefore pass these inheritable characteristics to their offspring.
◼There is competition for the available resources among the offspring which leads to a stable population in size after a period of time.
◼Darwin deducted that, variants of best adaptation will be selected for by natural conditions operating in the environment of the population at that particular period (natural selection).Therefore natural selection takes place, and the organisms with best variation will have selective advantage above others. Consequently they have higher survival rates compare to others in the population.
This is survival of the fittest by natural selection
, this is the second conclusion of Darwin theory.
Answer:
decomposer decomposes :) so it breaks down the organic matter into simpler compounds. it's very important process because complex compounds that build living organisms are not absorbable for other organisms, thus chemical cycling wouldn't be possible and the whole ecosystem would shut down. dead plants and animals would be everywhere and new organisms couldn't be born/grown. mold breaks down dead organic matter like dead trees. as the result simple compounds come into existence and can be assimilated by plants
Answer;
-Helium atom
Explanation;
-An alpha particle is identical to the nucleus of a helium atom.
-Alpha particle is one type of particles emitted during a radioactive decay, others being gamma and beta particles. Alpha particles are produced during the process of alpha decay.
-When an alpha particle is generated during a radioactive decay, the mass number of the radioactive particle increases by 2 while the atomic number increases by 4.
Silt, clay, and Sand would be more likely to find the sediment near location A, while cobble and boulder would be more likely to find the sediment near location B in the diagram of the stream.
<h3>What are Sediments?</h3>
Sediments may be defined as naturally occurring elements or materials that are broken down into small pieces of fragments due to weathering and erosion.
The sediments of silt are found in soil along with other types of sediments such as clay, gravel, and sand. While cobble and boulders are those sediments that are found in the mountainous part of the geographical locations.
Thus, it is well described above.
