22. Label the organisms in the food web below as producer (P), primary consumer (PC), secondary consumer (SC),
Paul [167]

In the above food web green algae is the producer, periwinkle and microscopic animals are primary consumers; mussel, barnacle, dogwhelk and crab are secondary consumers; dogwhelk and crab comes under tertiary consumer; dogfish is a quaternary consumer.

What is a food web?

It is a natural interconnection of several food chains in a single ecosystem. Each food chain supplies energy and nutrients through the ecosystem. There are four food webs producer, herbivores, carnivores, omnivores and decomposers.

Here green algae comes under autotrophs(prepares their own food), periwinkle and microscopic animals are herbivores(depend on producer); mussel, barnacle, dogwhelk and crab are carnivores(depend on herbivore); dogfish is an omnivore(depends on both producer and carnivore).

Polymerization and the break down of a polymer are two opposite reactions. What role does a water molecule play in both of them?
ladessa [460]
<span>In the process of polymerization, a chain of similar smaller molecules called monomer join together to create very large molecules called polymer. Through this chemical reaction, water is created as a by-product. In contrast to hydrolysis or breaking down of polymers, a water molecule is used to break the covalent bond that hold the components of a polymer.</span>

I need help... Any kind soul please help me ​
nikklg [1K]

Answer:

When the diaphragm contracts (it's a large flat muscle), it pulls the lungs down this causing expansion which eventually lead to inhalation of air. If it's injured, then that will be affected.

Why do methane is a gas at room temperature and water is a liquid, even though both molecules are similar in size and mass?
emmainna [20.7K]

Answer:

Water can hydrogen bond.

Explanation:

Liquids become gases once they are heated to a certain temperature. Heat is a form of energy. This change occurs when the intermolecular forces between the liquid molecules are energized enough to break. This breakage is necessary because gaseous molecules exist individually and do not interact with one another. That being said, it takes more heat to boil water because its intermolecular forces are stronger than methanes.

Intermolecular forces (IMF) are a result of partial charges on the molecular atoms that cause temporary bonds to form between molecules.

Methane is a nonpolar molecule, meaning each atom can only have slight partial charges. The strongest IMF methane participates in are London Dispersion Forces.

Water, however, is a polar molecule, with the hydrogens having strong partial positive charges and the oxygens having strong partial negative charges. This allows water to participate in a very strong IMF called hydrogen bonding. Again, because these partial charges are so strong, the water molecules can form stronger IMFs.

<u>*When molecules have stronger IMFs, they require more energy(heat) to overcome them.*</u>

The motion of a Foucault pendulum provides evidence that Earth
Assoli18 [71]
Rotates?
Ex: Foucault's pendulum is an easy experiment demonstrating the Earth's rotation. When Léon Foucault first performed the experiment in 1851, the concept that the Earth revolves was nothing new or radical; the pendulum's accomplishment was to provide a proof that did not require minute observations of the stars or other objects far removed from Earth. Foucault's pendulum is a highly localized, easily prepared experiment whose result is clear, powerful, and accessible even to the non-scientist. In short, the pendulum provides everything a science teacher could ask for in an instructional experiment.
