Answer:
as explained below:
Explanation:
it results as follow:
while you are jogging or doing any physical activity than your body requires alot of energy and produce a lot of carbon dioxide which causes the heart to beat fast as to remove co2 and take o2 from the blood leading to higher rate of pulse.
on the secon hand if you are sedentary , consumption and production of o2 and co2 respectively will decrease leading to the slow beating of heart leading to low pulse
Copied but correct answer.
Answer: C (She hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Answer:
The correct answer is - D. Helicase would no longer function, since the AMP-PNP is not hydrolyzed. ATP binding and hydrolysis induce the conformational changes that facilitate DNA unwinding by helicase.
Explanation:
During the replication process, helicase unzips or unwinds the double-stranded DNA. Helicase is a motor protein that uses ATP molecule hydrolysis in order to break the H-bonding between the strands of DNA.
If AMP-PNP added during DNA replication then it will bind to helicase and remains bound to helicase due to fact that it is a nonhydrolyzable ATP analog.
The answer is thirteen.
STR stands for <u>s</u>hort <u>t</u>andem <u>r</u>epeats. In this analysis, highly polymorphic regions with short tandem repeats are used. In FBI investigation, thirteen regions are analyzed and compared. The chance for two people to have the exact same thirteen regions is almost impossible (1 : 1 billion or less). This way a difference between two DNA profiles could be assessed.
