Answer: Tertiary consumers
A tertiary consumer in a food chain is an organism which is carnivorous in nature, which means it feeds upon other organism belonging to lower trophic level like secondary and primary consumers. In ocean foodchain the parrotfish feeds on marine plants which are producers and parrotfish is a primary consumer. This parrotfish is eaten up by big fish which is a secondary consumer. This big fish is feed up by shark. Therefore, shark belongs to tertiary consumers.
Emergency condition like Myocardial Infarction requires the immediate use of cardiopulmonary resuscitation (cpr).
<h3>What is Myocardial Infarction?</h3>
Myocardial infarction, another name for a heart attack, is an extremely serious condition caused by inadequate blood flow to your heart muscle. Although there are several potential causes, the most frequent one is a blockage in one or more of the arteries leading to your heart. Without blood supply, the damaged heart muscle will start to degenerate. If blood flow isn't quickly restored after a heart attack, there could be permanent cardiac damage and even death.
A heart attack is an emergency that puts your life in danger. If you think you or someone you're with is having a heart attack, dial 911 immediately (or your local emergency services phone number).

I think a relative frequency of alleles or genetic variation will remain unchanged for generations. For example if there is a 1 percent genetic variability in an organism of first generation, then the genetic variability in an organism of second generation will also be approximately 1 percent. There will not be a rapid increase in genetic variations. Mutation will not occur or if occur then it will be at the rate of equilibrium.
The direction will be toward the positive charge on the other end. If there are bubbles it means the current is running. DNA are molecules which stores genetic material. DNA is negatively charged because of the phosphate backbone since they are negatively charged also. To separate DNA using agarose gel electrophoresis, the DNA is loaded into precast wells in the gel and a current applied. Since the phosphate backbone of the DNA molecule is negatively charged, the fragments of DNA will migrate to the positively charged anode.
