Answer:

Option C.

Ocean acidification is the main ecological problem due to mariculture.

Explanation:

  • Mariculture also known as the aquaculture that stands for the fish farming occupation.
  • The main ecological problem that mariclture addresses is the environmental degradation especially the water pollution.
  • Many studies suggests that the tradition of mariculture has been increasing the acidificaton in ocean water that is directly affecting the marine organisms and plants.
  • A build up of organic material beneath fish farms impacts the flora and fauna of an area.
  • That makes drastic changes on sediment chemistry.

A species of fish evolved over thousands of years to have gills that allowed the fish to swim deep in the sea. What’s the effect
hammer [34]

Answer:

genetic modification     competitors     increase

Explanation:

The fish developed the gills because of <em>genetic modification</em>. Because the fish are now able to swim in deep water, their <em>competitors</em> in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will <em>increase</em>.

Which of the following examples describes convergent evolution?
topjm [15]

Answer: Option E (B and D are the only examples.

Mediterranean ecosystem with hot dry summer and fire can be found on various continents across the globe. Plants in these ecosystem have evolve similar adaptations to survive these circumstances.

Echidnas are egg laying mammals that live in Australia and new Guinea. They are sometimes known as spiny anteaters since they are covered in spines and mostly eat ants and termites. As such they resemble south American anteaters and hedgehogs but are not closely related to them. Instead echidnas descended from an aquatic platypus like ancestor.

Explanation:

Divergent evolution is a process where different organisms with different anscetors evolve independently and develop similar traits due to their adaptation to similar environment.

Another example is the similarities between hummingbird and hummingbird moth, the evolved from different ancestors and yet posses similar characteristics.

Describe how the<br> structure of DNA<br> determines the<br> structure of<br> proteins.
babymother [125]

Answer:

The Rules of Protein Structure. The function of a protein is determined by its shape. The shape of a protein is determined by its primary structure (sequence of amino acids). The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

In the cell, energy that drives endergonic reactions is often obtained from
IRISSAK [1]

Answer: B) energy released from exergonic reactions.  

Explanation:

Cell metabolism is the set of reactions that occur in the cellular environment to synthesize or degrade biomolecules to produce energy. Synthesis metabolism of biomolecules is known as anabolic (anabolism) and catabolic degradation (catabolism).

Endergonic reaction (product has more energy than reagents) and requires energy to occur. Anabolism occurs when the cell has sufficient energy or substrate. Catabolism, in turn, occurs in situations in which the body needs energy, such as between meals and fasting.

The reactions of anabolism and catabolism are opposite but occur in an articulated manner, allowing the maximization of available energy. Thus, while catabolism occurs spontaneously, an exergonic reaction with ATP production, anabolism is non-spontaneous, or endergonic, requiring energy to occur. In other words energy that drives endergonic reactions is often obtained from B) energy released from exergonic reactions.
