Answer:
B) be able to be disproven
Explanation:
Scientific investigations involve the use of scientific methods, which is a principled guideline for scientific observations. One of the steps of the scientific method includes formulating an hypothesis, which is a predictive statement about the possible solution to an observed problem. This hypothesis is FALSIFIABLE i.e it must via experimentation/testing be proven to be false.
This qualifies a happening or phenomena as SCIENTIFIC. It must be able to be repeatedly tested for the purpose of disproven or falsifying the hypothetical claim.
It is related to the direct
transmission of the pathogen to the open wound as the site. The open wound is
the portal of entry. It is the entry point of the microorganism to enter the susceptible
host and cause an infection.
Answer:
chlorophyll and accessory pigments allow algae to harvest and use the energy from sunlight
D
Explanation:
Flowing water has intrinsic kinetic energy that is harnessed to rotate the turbine. The turbine rotates hence gains mechanical energy because it is doing work. This work is used to rotate a dynamo of a generator which generates electricity. The mechanical energy is thus converted into electric energy by the dynamo. The electric energy is then carried by the power lines to the users.
