how does the enzyme present in the globular myosin head play its role during muscle contraction​

Answers

In addition to binding actin, the myosin heads bind and hydrolyze ATP, which provides the energy to drive filament sliding. This translation of chemical energy to movement is mediated by changes in the shape of myosin resulting from ATP binding.

What is an Non-native or Invasive species do to the environment?

Answers

Answer:

They can destroy the ecosystem or out - compete a native species.

Explanation:

For example, if an invasive species of tree is taller than the native species of tree and therefore takes up more sunlight, leaving the shorter native tree not enough sun, then it will effectively kill the native tree.

Also non - native and invasive are not the same thing. A non - native species doesn't necessarily mean it's invasive. It is only invasive if it begins to have a significant impact on the ecosystem it is inhabiting.

What happens to a species when the environment undergoes a radical change (e.g. due to climate, food source) and the organisms do not adapt? Explain your answer in not less than 3 sentences. May cite a hypothetical; situation to explain the answer.

Answers

Answer:

If an environment rapidly changes and an organism cannot adapt it will mostly die out. For example, some birds have long, thin beaks that let them reach insects inside trees. If these insects were to disappear for some reason and seeds became the main food source then the birds with long, thin beaks would not be able to eat. Other birds with different adaptations, like short, strong beaks, would be properly adapted to this new environment. So, this second species would replace the first species.

"Adaptations develop in response to environmental changes. For example, if a human population was displaced into the ocean, eventually the individuals would develop gills and fins to survive in the water." Is this statement true or false? Explain your answer.

For the following organisms, choose the correct order of increasing trophic level. a. fungi, deer, wolf and grass b. fungi, grass, wolf and deer c. grass, deer, wolf and fungi d. grass, fungi, wolf and deer Please select the best answer from the choices provided

Answers

Answer:

Your answer is C

Explanation:

The correct answer is for the following organisms, is grass, deer, wolf and fungi that is the option c as the  trophic level refers to the position of an organism in a food chain.

The trophic level refers to the position of an organism in a food chain or food web. In a food chain, energy flows from one trophic level to the next as organisms are eaten by other organisms. Grass occupies the first trophic level as a primary producer. Deer occupy the second trophic level as they feed on primary producers (grass). Wolves are carnivores and occupy the third trophic level as they feed on herbivores (deer). Fungi occupy the last trophic level as decomposers, so this is the correct order among all other options.

Thus, correct option is option c.

Answers

We can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

Why did the water vaporize and then condense?

As the water was heated by the electric heater, its internal temperature increased. Once this temperature reached the boiling point of water, the water vaporized or evaporated into a gas. This gas then reached the mirror, where it collected and cooled down, condensing back into a liquid in the form of water droplets.

Therefore, we can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

What property of water describes the molecule as acting like a tiny magnet?

Answers

Answer:

Intermolecular forces

Water is a dipole and acts like a magnet, with the oxygen end having a negative charge and the hydrogen end has a positive charge. These charged ends can attract other water molecules.

The entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each O−H bond, and therefore, the water molecules are polar in nature and act like little magnets.

Sea otters are dependent on their thick fur to keep them warm. Its unique structure traps air that insulates their bodies from the cold water. When an otter's fur is covered in oil, it can no longer keep the otter warm. This can cause hypothermia and even death. If the otter tries to clean its fur, it will ingest the oil, which is poisonous. In 1989, the Exxon Valdez hit a reef in Alaska. The ship spilled over ten million gallons of oil into the ocean.
