Develop an argument from evidence on how human activity can lead to ocean acidification? Further explain what we can do, as humans, to decrease the amount of ocean acidification occurring in aquatic environments.

Answers

Answer

Ocean acidification results from the solubility of CO2 in oceans increasing the H+ concentrations, and depletion of bicarbonates concentrations.

Therefore, human activities which increases the concentration of CO2 in the atmosphere, will raise the atmospheric  CO2 concentration. CO2 is constantly being absorbed by green plants maintaining   its concentration through carbon cycle,Therefore massive deforestation  which removes green plants, cutting  down photosynthesis is one of human activities which  raises CO2 levels of the atmosphere.The CO2 dissolves in  the oceans to raise its acidic levels.Lower pH.

Another source is fossil fuels emissions which add more CO2 to the atmosphere.

Sketch and label a food-web that includes at least 6 different items. Make
sure to have the arrows show how energy flows from one trophic level to
the next. ​

Answers

Answer and Explanation:

Example of a food-web:

(1) Algae --> (2) Protozoas --> (3) Krill --> (4) Cephallopods --> (5) Medium sized dolphin --> (6) Large Dolphin

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one.

1) The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. In this example, the autotroph organisms are algae, that make use of sunlight and inorganic matter.

The next links are the consumers:

2) Herbivores are primary consumers and feed on producers. In this example, herbivore organisms are protozoan.

3) Krills are the secondary consumers and feed on protozoans.

4) Some species of cephalopods feed on krill, among other species.

5) Specialized Cetaceans such as the Risso´s dolphin, feed especially on cephalopods, as they lack upper teeth and they only have a few teeth in their jaws.

6) The killer whale is a big sized-dolphin and a very important predator. It feeds on many animals, and one of them is the Risso´s dolphin.

The equation shows cellular respiration. During cellular respiration, glucose combines with oxygen to form carbon dioxide, water, and ATP.

Answers

Answer:

The correct answer is "The energy is transferred to ATP".

Explanation:

The missing information of this question is:

C6H1206 + 602 / 6CO2 + 6H2O + ATP

What happens to the energy in the bonds in glucose?

The energy is transferred to oxygen.

The energy is transferred to carbon dioxide.

The energy is transferred to water.

The energy is transferred to ATP.

The correct answer is "The energy is transferred to ATP".

During cellular respiration, the cell produces energy from the oxidation of glucose and it stores it in the form of adenosine triphosphate (ATP). The terminal phosphate group of ATP is highly energetic, and the cells breaks down ATP to use its energy in diverse chemical reactions. For this reason ATP is known as the "energy currency" or "coin of the cell".

What's the most common type of mutation observed in living populations, and what impact does it have on natural selection?

Answers

The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.

Answers

Answer:

Fuels with large hydrocarbon molecules are more viscous than fuels with small hydrocarbon molecules

Explanation:

Viscosity refers to runniness of a liquid. Fuels with large hydrocarbon molecules are more viscous as longer chains of large hydrocarbon molecules are easily entangled. Fuels with small hydrocarbon molecules are comparatively viscous as shorter chains of small hydrocarbon molecules are less likely to become entangled.
