The incorrect statement is as under :-
When these materials end up in the ocean, they support the growth and well-being of marine life.
<h2><em>
Explanation:</em></h2>
Waste materials like plastic, rubber, metal etc don't benefit marine organisms. In fact, they have very harmful impact on marine life forms.
Marine animals like fish, sharks, birds etc. tend to consume the plastic waste which is dumped in the oceans as waste product. After ingestion, it causes various complications in their bodies which may even lead to death.
Also, heavy metals like mercury, cadmium etc. are extremely toxic for fish. Their accumulation in the tissues of various fish causes poisoning in their body which impairs their normal body functioning.
Answer:
The vessels draining Myocardium of the heart join to form <u>Coronary Sinus </u> that ultimately opens into <u><em>THE RIGHT ATRIUM.</em></u>
Explanation:
<u><em>CORONARY CIRCULATION:</em></u>
The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.
<u>Coronary Arteries</u> supply oxygen rich blood to the myocardium and <u>Coronary Veins</u> remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.
The correct answer is: a gene may represent only a millionth of the cell's DNA.
The method used to amplify DNA fragments is called polymerase chain reaction (PCR). PCR is a technique used in molecular biology to produce thousands to millions of copies of a single targeted DNA sequence. When studying a specific gene, the scientist needs to be able to target and focus only on the DNA sequence which constitutes this exact gene. However, a gene is only a very small portion of an organism's genome. Therefore, the scientist uses PCR to amplify this DNA sequence and produce a large number of copies.
