C2H6 + 4o2 → 2CO2 + 3H2O...
I think it's electric force. Not 100% sure but I hope it's right.
Answer:
The reticular layer of the dermis (RD) consists of dense irregular connective tissue, which differs from the papillary layer (PD), which is made up of mainly loose connective tissue (note the difference in the number of cells).
Explanation:
Hope this helps...
The answer is In the tunica, cell divisions are perpendicular to the stem axis, giving rise to thick layers of <span>tissues covering the outside of the tip. </span>
The tunica is a membranous structure which covers the plant organs. It is responsible for the characteristics of leaf edges and margins in the monocots. During the plant growth, perpendicular cell divisions regarding the stem axis result in the membranous<span> structure outside of the tip.</span>
Answer:
Only options A (first one) reflects the instances with valid experiment or conclusion.
Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.
Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).
Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.
Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.
Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.
