Explanation:
Cardiac muscle is present only in the Heart of organisms which is involuntary in its action. The heart helps the blood to pump throughout the body.
Cardiac muscle shows the presence of intercalated discs which contain desmosomes and gap junctions. It is the presence of these gap junctions the muscle cells of the heart functions as a single functional unit due to the transmission of depolarizing current from cell to cell to different chambers of the heart.
Thus, option C is the correct answer.
So what roles do society, politics, and economics play in science?Economics determines how much money is available to fund scientific research. Certain federal grants come directly out of the national economy, which determines if certain research projects can continue or are cut off.Politics affect science by passing some bills that directly affects science, congressmen can determine whether those funds from the economy will be used for research or not. Just a side note: wealthy lobbyists control alot of what politicians do, by donating millions into their election campaigns. Society affects science by our citizens democratically electing those politicians that we think will or will not endorse scientific research projects. For example, embryonic stem cell research has been under fire by conservatives for taking future babies' cells to study. Liberals, however, tend to be in favor of change and new advances scientifically

if you need it shorter "Society, made up of the country's citizens, can influence science by electing politicians (president and congressmen); the politicians can then affect the economic funding of scientific research, either by increasing or decreasing government grants to scientific projects."

Answer:
1. Explain why predators need to eat more than primary consumers.
Explanation:
Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.
The scientist that thought he had proven that plants obtain their nutrients from water rather than soil is Van Helmont.
