Explain how abiotic factors can have influence on the survival for individuals through natural selection.

Selection: Organisms live within ecosystems, which are made up of various biotic and abiotic factors. These factors contribute to selecting which variations provide the individual with an increased chance of surviving. ... Examples of abiotic factors include temperature, shelter, sunlight, water and nutrients.

Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.

Abiotic factors

Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...

Biotic factors

Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...

The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.

The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.

So, the abiotic factors are controling the biotic factors of an environment.

answer///multiple alleles;

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
