Answer:
Centríolo. Los Centríolos son orgánulos tubulares (en pares de dos en dos) que se encuentran en el citoplasma de las células animales, cerca de la membrana nuclear. Los centriolos tienen la función de organizar los microtúbulos, que son el sistema esquelético de la célula.

Water isn’t wet, Wetness is a description of our experience with water. What happens to us when we come in contact with water is called being wet
Answer:
Observational study
Explanation:
An investigation of what happened over the years to the people who were exposed to radiation during the 1986 Chernobyl nuclear disaster would be termed <u>an observational study</u> because it will require observing subjects and finding out if there is a kind of correlating factor in the subjects that could indicate the level of exposure to the nuclear radiation.
There are basically two types of research studies:
1. Observational studies
2. Experimental studies
Observational studies involve just the observation of subjects and trying to find out some correlation factors. This kind of study could be prospective when it deals with what could happen in the future based on certain factors or retrospective when it considers what has already happened. An observational study can be cross-sectional, case-only, case-control, or cohort study.
Experimental studies are also referred to as randomized or controlled trial studies. Here, subjects are grouped and each group receives a different treatment in order to isolate the effect of a particular factor or variable relating to the treatment.
Answer;
Br2 + 2e− → 2Br− = 1.07 V
Explanation;
-Oxidation is the loss of electrons while reduction is the gaining of electrons. Reducing agent undergoes oxidation while oxidizing agent undergoes reduction.
- In the above question, bromine is the strongest reducing agent because it has the highest positive value of an emf. Zinc ion on the other hand is the strongest oxidizing agent since it has the highest negative emf.
The difference between the two is, cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. Fracture is the property of a mineral breaking in a more or less random pattern with no smooth planar surfaces.
