OB. Invest in alternative energy sources to reduce emissions.
O C. Reduce road construction to dissuade new residents.
O D. Reduce air-quality regulations so businesses can grow unimpeded.

Answers

Answer:

B. Invest in alternative energy sources to reduce emissions.

Explanation:

The best way to help a city as its population grows, and its air becomes more polluted, is to invest in alternative energy sources to reduce emissions. The correct option is B.

What is pollution?

Pollutants are the name for these dangerous substances. Natural pollutants include volcanic ash, for example. They can also be brought by human activities, such as factory runoff or waste.

Air pollution is caused by solid, liquid, and gaseous pollutants. These gases and particles can be produced by factories, volcanoes, wildfires, dust, pollen, and vehicle and truck emissions.

To stop pollution, we must use alternative energies that do not cause pollution.

Thus, the correct option is B. Invest in alternative energy sources to reduce emissions.

Explain the relationships between dehydration synthesis, hydrolysis, monomer, and polymer

Answers

Answer:

combine with each other using covalent bonds

Explanation:

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.

Answer:

Dehydration synthesis is a process by which two monomers are linked to form a polymer, with water being given off as a byproduct.  Conversely, hydrolysis is the process by which water is introduced in order to break down a polymer into its monomer building blocks.

Which of the following most accurately describes what affects Earth's ocean tides?


The Sun and Moon, but the Sun impacts Earth's tides more because it is closer in distance to the Earth.


The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.


The Sun and Moon, but the Sun impacts Earth's tides more because it much more massive than the Earth.


The Moon is the only celestial object that influences Earth's ocean tides because it so close in distance to the Earth.

Answers

The answer option that most accurately describes what affects Earth's ocean tides is: B. The Sun and Moon, but the Moon impacts Earth's tides more because it is closer in distance to the Earth.

A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the combined effects of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.

Hence, an ocean tide describes the episodic changes in the height of the surface of an ocean as a result of the gravitational force of attraction exerted by the Moon and Sun on planet Earth.

In conclusion, the Earth's ocean tides is largely affected by the gravitational force of attraction exerted by the Moon than that of the Sun because the Moon is closer in distance to the Earth (approximately 400,000 kilometers).

Since the 1950s, the exploitation of the rare-earth elements has increased from a few tonnes per year to over 150 000t per year. They are used in a wide range of applications, including new developments in transport, electronics and healthcare.
Although the main metals used following the industrial revolution are still important, economic development since the mid 1900s has involved the use of relatively small quantities of a much wider range of metals.

membrane molecules that use the energy of atp to move ions against a concentration gradient are called

Answers

Membrane molecules that use the energy of ATP to move ions against a concentration gradient are called PUMPS. This type of transport is called active transport.

Active transport is a type of transport that requires energy (e.g, ATP) to move molecules and/or ions against a concentration gradient.

In active transport, specific membrane transporter proteins referred to as pumps are used to move ions against an electrochemical gradient across biological membranes.

These protein pumps are fundamental for creating electrochemical gradients that are subsequently used by cells for diverse purposes (e.g., muscle contraction).
