Answer:
We can use non-plastic water bottles, use reusable ziploc bags, use a felt grocery bag, fill a bucket of water while you are showering then afterwards use it to water plants.
this all can help because it is our reusable and the plastic things can end up in the ocean (ocean/ water is a natural resource).

The picture shows a diver constructing artificial reef in a shallow area of the ocean. artificial reef is intended to affect the ocean ecosystem by-
A. removing pollution from the water
B. Providing shelter for marine organisms
C. Causing sediment to erode into deeper waters
D. Preventing people from overfishing along the shore
Answer:
Everyone, the answer is actually B. Providing shelter for marine organisms
Explanation:
We just went over this question in class, this is the right answer. Causing sediment to erode in the waters just doesn't make any sense.
The materials which are used to construct artificial reefs includes rocks, wood, old tires, etc. The artificial reef affect the ocean ecosystem by providing shelter for marine organisms. The correct option is B.
What is an artificial reef?An artificial reef is defined as the manmade structure which may mimic some of the characteristics of the natural reef. The submerged shipwrecks are the most common form of artificial reef. The oil and gas platforms, bridges, etc. and other offshore structures are also function as artificial reefs.
From tourism to marine recreation and also for sport fishing, the reefs play an important role in local economies. They are also important for the health of the ocean and provides habitat for the variety of marine life and support the ocean ecosystems.
The artificial reefs are generally constructed to protect and enhance or restore the components of the marine ecosystems.
Thus the correct option is B.

How are the cells produced through mitosis and meiosis different?
Answer:
In mitosis 2 identical cells are created, but in meiosis 4 sex cells are created.
Explanation:
In mitosis there are 5 stages. These stages are prophase, prometaphase, metaphase, anaphases, and telophase. In meiosis there are also 5 stages, they are the same phases, they just end with II. (Ex. Prophases II)
When a comet enters the solar system, it curves toward the sun. Which statement describes why the sun does not move when a comet is nearby?
Answer:
Explanation:
When a comet enters the solar system it curves towards the Sun due to the Sun's gravitational pull. Every celestial object in the universe has a gravitational pull whose force is dependent on the object's mass. The larger the object is the more gravitational pull it will have. The Sun is the largest object in our Solar system and therefore has the most gravitational pull. This is why the comet curves toward the Sun, but the opposite does not happen because the comet's gravitational pull is not strong enough to pull the Sun.

Solution A has a pH of 3, and solution B has a pH of 5. Which statement best
describes these solutions?
A. Solution B is more acidic than solution A
B. Solution A is acidic, and solution B is basic.
C. Solution B is less acidic than solution A.
O D. Solution A is basic, and solution B is acidic.
Answer:
The answer will be C
Explanation:
Solution A has a pH of 3, and solution B has a pH of 5 "Solution B is less acidic than solution A".
What is pH ?The chemical circumstances of such a solution are reflected by pH, which is an essential quantity. The pH might influence nutritional availability, biological functioning, microbial activity, as well as chemical behavior.
What is acidic?Acidic substances were characterized by a sour flavor. An acid is a molecule that can give an H+ ion while remaining energetically stable.
It is known that if pH ≥7 then solution will be acidic
Hence, solution B is less acidic than solution A.
Therefore, the correct answer will be option (C).

k2co3 major species present when dissolved in water
When K2CO3 is dissolved in H2O (water) it will dissociate (dissolve) into K+ and CO3 2- ions. To show that they are dissolved in water we can write (aq) after each. The (aq) shows that they are aqueous – dissolved in water.
The major species present in the solution when K₂CO₃ dissolved in water are K⁺, CO₃²⁻ , and HCO₃⁻.
What is the interaction between salt and water?When salt is added to water, the salt dissolves because the ionic bonds in the salt molecules are weaker than the covalent bonds of water. The salt dissolves in water at the molecular level due to electrical charges. Due to the fact that both salt and water are polar.
The bonds in salt are ionic bonds and to dissolve the salt, the positively-charged side of the water is attracted to the negatively-charged ions of salt and the negatively-charged side of the water is attracted to the positively-charged ions of salt.
The dissociation of the potassium carbonate in water:
K₂CO₃ (aq) → 2K⁺ (aq) + CO₃²⁻ (aq)
H₂O (l) → H⁺ (aq) + OH⁻ (aq)
Carbonate ions are combined with hydrogen ions from water:
CO₃²⁻ (aq) + H⁺ (aq) ⇆ HCO₃⁻ (aq)
Therefore, K⁺, CO₃²⁻ , and HCO₃⁻ ions are present when K₂CO₃ dissolved in water.
