List 3 to 4 environmental factors that may have or hindered your plants from developing roots

Soil physical condition, pH and climatic condition

Explanation:

The following environmental condition affects the growth of roots of plant –

a)Soil physical condition – If soil is extremely wet or dry, the roots of the plant do not grow efficiently and remain underdeveloped.

b)Soil pH condition – The soil can grow in optimum pH condition. If the soil is extremely acidic or alkaline the plants will not be able to take up the essential nutrients from the soil.

c)Extreme cold or heat climatic condition,  the growth rate of plant will become slow and hence the roots do not develop to their full length.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
