The brain injury suffered by Phineas allowed psychologists to learn about the functions of the brain's FRONTAL LOBE.
The man case was the first one in which a brain damage will result into a change in personality. The damage to the Phineas frontal lobe helped scientists to recognize the connection between the frontal lobe of the brain and social cognition and decision making.<span />
Answer:
The answer is the VPg Protein.
Explanation:
The question is incomplete, here is the full question:
Poliovirus is a positive-sense RNA virus of the picornavirus group. At its 5' end, the RNA genome has a viral protein (VPg) instead of a 5' cap. This is followed by a nontranslated leader sequence, and then a single long protein coding region (~7,000 nucleotides), followed by a poly-A tail. Observations were made that used radioactive amino acid analogues. Short period use of the radioactive amino acids result in labeling of only very long proteins, while longer periods of labeling result in several different short polypeptides.
What part of the poliovirus would first interact with host cell ribosomes to mediate translation?
A) the poly-A tail
B) the leader sequence
C) the VPg protein
The part of the host cell ribosome that the poliovirus would interact first is the VPg protein because the poliovirus has to affect the RNA to be able to replicate it's own DNA and the VPg protein is attached to the RNA's 5' end.

An individual who has a high level of cardiovascular fitness will have a LOWER Resting Heart Rate at any activity level than an individual who is unfit AND an individual who has a high level of cardiovascular fitness will have a LOWER Stroke Volume than an individual who is unfit is a <u>true</u> statement.
Explanation:
Resting heart rate is a cardiac marker and at normal conditions, the resting heart rate of an adult ranges anywhere between 60 to 100 beats per minute.
As far as efficiency of heart or cardiovascular fitness is concerned, a lower resting heart rate is the general benchmark. An athlete who exercises properly may have a resting heart rate even less than 60 which is good for heart health.
Exercise strengthens the heart or cardiac muscles which provide more energy for the cardiac muscles to pump more blood per one heart beat as one exercises. So without increasing the heart rate, more blood is pumped and increases stroke volume.
This is the reason why the stroke volume is also increased in a person with high level of cardiovascular fitness.
Aerobic exercises are the best to lower resting heart rate.
Whereas cardiac muscles become weak due to lack of exercise, which requires the heart to beat more times to pump blood per minute. Lack of exercise, anxiety, stress, dehydration, lack of adequate sleep, and any other underlying medical conditions can increase the resting heart rate.
