Answer:infectious disease
Explanation:
.
Objective means that they are "facts", and do not include personal thoughts and beliefs (which is subjective).
In this case, your answers are:
1) Fact:
Facts are made based on data and analysis, and are supported by details and other known "facts" or <em>truths</em>. This means that they are right in any circumstances in most cases, or at least in the given circumstance that is provided.
2) Data:
Data is used to support the fact, which is objective. Without data, the claim would be seen as a opinion, or subjective, in meaning, a "I feel that it is this way". Without data, you will not have facts.
It is not:
3) Opinion:
Opinion is the antonym of Fact, and so if Fact is a answer choice, then Opinion is not. Opinion is based off of feelings, personal knowledge, and personal preferences. While useful in some cases, it is not objective.
4) Theory:
A theory is not objective, because it is a opinion that is provable (but is yet to be proven). This makes it subjective, until proven right.

Actin is a family of globular proteins that form microfilaments, one of the three fundamental components of the cytoskeleton of the cells of eukaryotic organisms (also called eukaryotes). It can be found as a monomer in free form, called actin G, or as part of linear polymers called microfilaments or actin F, which are essential for cellular functions as important as cell mobility and contraction during cell division.
So, from the name, we can say that carbon dioxide has two oxygen atoms. Alternatively, we can use the chemical formula of the molecule. Carbon dioxide has a chemical formula of CO2 .
Answer:
Island finches did not have beaks of the same size and shape
Explanation:
This is the evidence of variation, and therefore proof that the finches were able to survive the selective pressure by adapting their beaks to different feeds. Therefore finches that were able to adapt adjusted their beak shapes to the selecting pressure 'feeds' in the environment, and are naturally selected, and therefore adapted and evolved with time .While those without the surviving beaks lost out.
Thus changes in selection pressure, necessitated corresponding change in the beaks shape for adaption to survive( due to variation, ) and therefore natural selection for evolution
