Mutation can cause DNA to change
Answer:
Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.
Explanation:
As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.
Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.
In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.
Answer:
"The latitude of a region determines how much sunlight the area receives" this statement says about why the latitude of a region influences its climate.
Explanation:
The latitude determines the sunlight of the area receives because, the more the latitude the sharper will be angle of the sun's rays which will reach the surface. Means that the rays of the sun are being spread over the broader area. Hence, More the latitude receive will be the less than the lower latitude areas located nearer to the equator. As, we know the sun's ray first strikes over the Earth's surface which is near the equator as these places receive direct solar radiation. At greater latitude the solar radiations gets spread in more area and hence the temperature also reduces.
Answer:
The Six Kingdoms. When Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells. Today the system of classification includes six kingdoms.
Explanation:
Together the insulin and glucagon help maintain a state is known as homeostasis in which conditions inside the body remain steady.
<h3>
What is homeostasis?</h3>
Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
When blood sugar is too high, the pancreas secretes more insulin. When blood sugar levels drop, the pancreas releases glucagon to raise them.
