Answer:
Helicase
Explanation:
DNA helicase removes the hydrogen bonds that connect the bases of each DNA strand, which allows for the replication of strands
Well, if you say "I just stood up" ,no doubt, u were previously sitting or even lying down. When u are sitting or lying down ur heart does not require much force or energy to send blood to the upper part of the body. But when u stand there is no chair to neutralize or reduce the effect of gravity on you, therefore the heart rate increases so that blood can be efficiently sent to the upper part of the body.
Please mark me as brainliest.
The three components that are common to the circulatory systems of most living animals are: B. VESSELS, HEART, CIRCULATING FLUID.
Blood is the circulating fluid. It is the connective tissue of liquid plasma and cells.
Heart is a muscular pump to move the blood and have it circulate throughout the body of living animals.
Blood vessels are arteries, capillaries and veins that deliver blood to all tissues.
The Circulatory System has two types. They are the open circulatory system and the close circulatory system.
An open circulatory system is one where the blood does not circulate inside blood vessels but also flows into cavities that irrigate tissues.
A close circulatory system is one where the blood circulate only inside the blood vessels.
Answer:
Benedict's test which is meant to detect non-reducing sugar like sucrose from reducing sugars like glucose, fructose or galactose can be used to identify sucrose.
Explanation:
Glucose, fructose and galactose are reducing sugars so they can easily be identified against non-reducing like sucrose. A reducing sugar is a kind of sugar which has a free aldehyde or ketone group. Free aldehyde and ketone groups act as a reducing agent and they are capable of reducing other substances. In this situation, the reducing sugar reduces other substances and themselves get oxidized. In contrast to this, a non-reducing sugar can not act as a reducing agent because it has lack of a free aldehyde or ketone group.
Benedict's test is a test which is used to identify a non reducing sugar from reducing sugars. In this test, a reducing sugar (Glucose, fructose or galactose) is heated with Benedict's solution which leads to the change of color of solution to orange-red/ brick red. But no such color change will be detected if sucrose is heated with Benedict's solution.
