Biological Weathering<span>Biological weathering would include the effect of animals and plants on the landscape. This is more than roots digging in and wedging rocks. Biological weathering is the actual molecular breakdown of minerals. There are things called </span>lichens<span> (combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area. You might find more activities like lichens near oceans where the air is humid and cooler. </span>
A confounding variable refers to an external effect, which modifies the influence of an independent and dependent variable. This extraneous effect is used to affect the outcome of an experimental design. The confounding variables can ruin the experiment and can generate unnecessary outcomes.
In the given case, confounding variables can be introduced by testing multiple hypotheses at a time and by using distinct kinds of soil in each of the samples.
<span>The portion of the cell is absent in Rhizopus stolonifer with the exception of the reproductive cells is septa, the internal crosswalls. It functions as a wall that divides cavities into smaller ones. </span>I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:
Exercise
Explanation:
Cognitive impairment is the condition where a person has difficulty in recalling or remembering things. They also find it difficult to perform daily tasks and make decisions. They are not able to concentrate hence also have trouble learning new things. Cognitive impairment can be present genetically although it is observed almost in a large number of ageing people.
Exercise has been proven to help in cases of mild to severe cognitive impairment. In an experiment it was proven that 6 months of aerobic exercise reversed cognitive impairment symptoms in ageing people. It particularly benefits people carrying the APOE4 gene variant responsible for making people susceptible to Alzheimer's.
