Answer:
The correct answer is c. the truck driver.
Any object is said to be the motion if its relative distance with respect to a reference point is keep on changing.
For example, a kid travelling through a train might seem to be stationary with respect to the seat. However, he would seem to be moving if we see him in respect to the railway track outside the train.
A reference point is anything (place, person or any object) used to determine if something or someone is in motion.
In the given situation, the distance between truck driver and bulldozer will remain the same throughout the journey as it is being placed on the back of the truck. Hence, the correct answer is truck driver.
Explanation:
coding regions, called exons, which specify a sequence of amino acids.
non-coding regions, called introns, which do not specify amino acids.
regulatory sequences, which play a role in determining when and where the protein is made (and how much is made)
Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:
W = Force x distance
W = 84 J = F (7.0 m)
F = 12 N
Hope this answers the question.
Part I
NO, this is because of different judgement as to when pulse start/stops.
In addition, computers are more sensitive than probes, prob could be more accurate because it does not have human error, which manual method has. Other factors that affect the reading may include temperature, eating, body position among others.
Part II
The causes of changes in blood pressure that might occur within a given day include; stress and level of activity. Eating a flux of nutrients like sodium could affect the blood pressure. Also different requirements from the body . Therefore, if one is lying down versus when one is standing up, it might take more energy standing up, such that when one is relaxing lying down, blood pressure will be lower due to the relaxation.
Part III
What is needed to be kept constant through out the experiment is;
same person, same amount of time in between readings or for the readings, same pressure that is pumped at the beginning, same temperature.
It is important to keep all those factors constant because if not, the factors that are not iv's could change the data. keep the same person because data can change a lot based on who you use while retrieving the data.
Part IV
Prehypertension is the sign that one might have high blood pressure in the future. it is valuable to know if one is considered prehypertensive because one can implement proper changes to lifestyle in order to maintain a healthy blood pressure.
Part V
An ACE inhibitor works by blocking the body from producing angiotensin II which causes blood vessels to become narrower, raising blood pressure. This stops the chemical, thus relaxing the blood vessels and also lowering the blood pressure.
