why did the researchers add filtrate which macerated moss had been removed to control microcosms?(worth 5marks)

1 answer:

5 0

The researchers in question opted to remove the macerated moss from the control group in order to guarantee that the results were accurate.

The experiment in question consists of:

Placing volcanic rock samples into two glass containers
Adding to one container the mixture of macerated moss and water
The other container is the control, it receives only water
The goal is to measure the release of minerals from the rocks.

When performing an experiment, the control group is of vital importance. The presence of a control group ensures the accuracy of an experiment.

Given that moss is grown on rocks and will erode the rock over time, the researchers opted to remove it from the control sample. Minerals present in the rock might mistakenly be measured as minerals released from the volcanic sample, thus making the results of the experiment inaccurate.

Canine teeth of human beings are called vestigial organs and archaeopteryx is called a bridge animal,why?

Alexxandr [17]

Canine teeth are not as useful as it is in animals while archaeopteryx has the character of both birds and reptiles.

<h3>What are vestigial organs?</h3>

The vestigial organs are those organs that have no apparent function in the body which means that the body can do without them.

Examples of vestigial organs in the body are:

appendix

wisdom teeth

The canine teeth is a type of teeth in mammalian dentition and is said to be vestigial because man can do without it.

Archaeopteryx are animals that has the characteristics of both birds and reptiles because it bears wings like birds and has hands it uses to crawl like a reptile.

svlad2 [7]

Scientists should not have the ability to patent their own research methods as this prevents additionally scientific knowledge to be present within the experimental sciences. The last step of the scientific method is to communicate and share your own findings, and without the ability to do so, it prevents constructive criticisms of the method as well as improvements that would otherwise be prevented from patenting. In the field of genetic engineering specifically, the Human Genome project or (HGP) was an international scientific investigation that promoted communication between scientists rather than the restriction of scientific knowledge. The results of this international collaboration led to multitudes of information being presented regarding human genetic makeup. Therefore, patents ultimately prevent the progression of the sciences and scientific knowledge.

I dont know if there are typos but hopefully this helps.
