Answer:
Vaccines are important in order to prevent infections of more dangerous viruses because with the help of vaccine body makes antibodies which helps in protecting the body against viruses.
Explanation:
There is no medicine present in vaccines. Vaccine contains dead virus which is injected in the body. When the immune system detect these viruses, they make antibodies that are effective in controlling the virus. When these viruses attack again, the body is prepared for it.
The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
Answer:
See the answer below
Explanation:
It may seem that the question is incomplete. The complete question reads:
Match each statement to the type of behavior it describes. Jenna published the results of her latest experiment for the public to see. Malcolm altered an experiment to be able reach his desired conclusion. Elena keeps complete records of all her experiment results. Neal shared the results of his field study even though they didn’t support his hypothesis. <em>Put each description to the group it belongs to. 1.Responsible 2.Irresponsible.</em>
<em>To answer the question:</em>
<em>Responsible behavior</em>
- <em>Jenna published the results of her latest experiment for the public to see.</em>
- <em>Elena keeps complete records of all her experiment results.</em>
- <em>Neal shared the results of his field study even though they didn't support his hypothesis.</em>
<em>Irresponsible behavior</em>
- <em>Malcolm altered an experiment to be able to reach his desired conclusion</em>
Responsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.
Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.

Answer:
SA Node
Inter-nodal Pathways
AV Node
AV Bundle
Bundle Branches
Purkinje Fibers
The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.
Answer:Human height
Explanation:
Inheritance patterns are often more complex than predicted by simple mendalian genetics. When Mendel studied some phenotypic characters, like the human skin color and height, they were found to be an addictive effect of two or more genes on a single phenotypic character. These are called quantitative characters, which usually indicates polygenic inheritance.
The human height is an example of quantitative character, it is controlled by at least 3 genes having 6 alleles. 3 genes with 6 alleles from both parent can give rise to wide range of phenotypic character (heights).
