Answer:
C: Take infected amphibians and assign them to two populations. Leave one population alone; inoculate the other with Jl. Measure the rate at which infection proceeds in both populations.
Explanation:
In scientific investigations, the best way to determine the effect of certain experimental factor on the population of study is to have a baseline for comparison. This is usually referred to as controlled experiment.
<em>In the case of the observation that chytrid infection in amphibians seems to be inhibited by Janthinobacterium lividum, the best way experimental design is to get a population of amphibians suffering from the disease, divide them into two groups and subject them to the same conditions except the introduction of Janthinobacterium lividum to the skin of one of the groups.</em>
<em>A suitable method can thereafter be employed to measure the rate at which infection proceeds in both population. If indeed, the bacterium has the capacity to inhibit the infection, the rate of infection in the group with the bacterium will be significantly less than that of the group without the bacterium. </em>
The correct option is C.

The answer is none of the above because organic materials, gasses, and minerals are all component soils.

If it was wrong I’m very sorry
Meiosis is needed for sexual reproduction, here chromosome number is halved, it provides for mixing up of genes.
mitosis is needed for growth, repair, replacement, asexual reproduction.
it maintains same chromosome number
1 - V=150 cm3
2 - 180 divided by 150= 1.2 g/cm3
3 - The mass would stay the same on the moon as on Earth because mass is just how much matter is in an object. However, the weight would be different because the gravitational pull is weaker on the moon than it is on Earth.
4 - The density is greater than the density of water which is 1 g/cm3.
5 - No because one solid could be a heavier material than another solid.
9 - Mass: gram (g) or kilogram (kg). Volume: liter (L) or centimeter (cm). Density: g/cm3 or g/mL
