Answer:
A. Gravity
Explanation:
The strong gravity, or "Pull" of the Earth is what keeps the moon in orbit.
I hope this helps!
Khan Academy is great! Also, Alison (it's a website) has some free courses as well.
<span>The question says, the corn we eat today is larger and has more kernels than the corn people first grew thousands of years ago. Which process is most likely responsible for the changes that have occurred. The correct option is 'succession'. Succession is the process by which change occur in the composition, structure or architecture of a specie over a period of time.</span>
Answer:
Biotechnology.
Explanation:
Biotechnology may be defined as the field of biology that uses the living organisms to make product by using molecular techniques. Biotechnology involves the different field like biomedical engineering, biomanufacturing and bioengineering.
The genetic system of the living organism can be modified to obtain the desired products. Artificial insulin is prepared by the application of biotechnology. The new drugs in the market and desired trait in the living organism can be prepared by the biotechnology field.
Thus, the correct answer is biotechnology.
Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.
Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.
