The chemical group is the methyl group (-CH3).
The iron-rich minerals present in the magma align themselves with the already existing magnetic field of the Earth. When the magma starts to cool down, the iron rich minerals are the first to solidify first. The magnetic field of the Earth align these minerals as the needle of the compass. The alignment of these iron-minerals is fixed once the magma is solidified completely.
Hence, the given blanks can be filled with 'iron and solidify'. respectively.
Answer:
The DNA is a double stranded nucleotide. The DNA is consisted of deoxyribose sugar, phosphate group, and nitrogenous bases such as adenine, thymine, guanine, and cytosine.
The adenine always base pairs with thymine, so whatever the percentage of an adenine in a DNA strand is, always the same with thymine. Same thing with Guanine as it always base pairs with Cytosine.
A = T
G = C
Explanation:
Let's take the cow as an example.
If its adenine content is 28%, it has also 28% thymine content. 28 + 28 = 56% So, the remaining percentage is G and C, which is 44%. The 44% will be consisted of 22% guanine and 22% cytosine, making it 100%.
look at the picture
Answer:
Tricuspid valve is a structure present between right atrium and right ventricle. It is a one way valve composed of three flaps, hence the name. Blood flows from right atrium to right ventricle via it. It also prevents back flow of blood to atrium.
If a water filled right ventricle is squeezed, it will try to flow back into the right atrium. At this moment, the flaps of tricuspid valve will move upwards in horizontal position. As a result, the valve will close and water will not flow back to the right atrium.
