Answer:
The correct answer will be- placebo effect
Explanation:
In the given question, the experiment was performed to test the effect of a new drug on humans in which the new drug was given to the experimental group but a non-effective drug to the control group.
This type of study on the control group is known as the placebo effect in which the treatment is provided not on the basis of the drug but on the belief system that the provided drug will treat the problem.
In the given question, the people of control group believed that they received the real treatment which is not the case. Thus, they were provided with the placebo effects.
Thus, the placebo effect is the correct answer.
Answer:
There is a 50% chance their child will have blue eyes.
Answer:
The correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Explanation:
Scientists could not use DNA evidences to make a complete phylogenetic tree of Icthyosaur as there are no blood samples or other DNA molecules to create DNA printing or mapping to create phylogeny with the modern dolphins. They only can be make similarities based on the morphological characteristics of these two groups.
Thus, the correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Answer:
read description
Explanation:
Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules to support growth or to release energy. Matter is conserved during cellular respiration because atoms are conserved in physical and chemical processes.
Answer:
Organisms have different proportions of bases in the DNA.
Explanation:
Option B is correct because different organisms have different proportions of bases in their DNA. This makes each species unique. This means that it is not possible for multiple species of have similar proportion of DNA bases.
Other options are incorrect because of following reasons:
1. All the genetic information cannot be universal among all organisms. Different species performs different functions and the genetic information differs accordingly.
2. All animals cannot have similar amount of bases in their DNA. Different animals have different bases.
3. The given table doesn't say that plants are least related. In fact, all organisms differs in terms of DNA bases proportion.
