Answer:
Option B
Explanation:
Nitrogen fertilizer runoff into the farmlands results into Eutrophication which is a form of nutrient enrichment of the water body. Because of the nutrient enrichment, the productivity of the water increases and hence the oxygen level of the water reduces thereby degrading the quality of water and adversely affecting the aquatic life in the water body
Hence, option B is correct

Describe the importance of Tiktaalik roseae to the study of evolution.
Answer:The discovery of well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins.
Explanation:can i have brainless?
Tiktaalik roseae was famous for his discovery of well-preserved pelves and a partial pelvic fin in aquatic organisms. These structures support aquatic organisms to a large extent.
What is Evolution?Evolution may be defined as a methodology through which gradual changes in organisms may take place over many generations. Due to this, a species of animals, plants, or insects slowly change some of their physical characteristics and adapt to nature.
According to the context of this question, it was the time of about 3.75 million years ago, when the transition between fish and first-legged animals was observed. This observation clearly demonstrates that the evolution of hind legs in the animals was actually initiated through the hind fins of the fish.
Therefore, the importance of Tiktaalik roseae to the study of evolution is understood by the fact of describing well-preserved pelves and a partial pelvic fin in aquatic organisms.

If a sample of DNA is 21% adenine, it would be % cytosine.
Answer: 28%
Explanation:
Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio
21% Adenine and 21% Thymine
21% + 21% = 42 100 - 42 = 56 56 / 2 = 28
28% Cytosine and 28% Guanine

Explanation:
Most waves are created by ocean currents
Answer: yes
Most waves in the ocean are wind generated waves. Ocean surface currents are produced by major overall patterns of atmospheric circulation, the Coriolis Effect and the shape of each ocean basin. Ocean surface circulation brings warm equatorial waters towards the poles and cooler polar water towards the equator.

What is the probability that a female offspring of the cross that is shown above would have a recessive allele for Duchenne muscular dystrophy disorder?
0 percent
25 percent
50 percent
100 percent
A female offspring of the cross has a 100% chance of having a recessive allele for Duchenne muscular dystrophy disorder. The correct option is 4.
What is Duchenne muscular dystrophy?Duchenne muscular dystrophy is a recessive genetic disease caused by a faulty allele.
Duchenne muscular dystrophy is an X-linked recessive disorder, which means that the gene responsible for the disorder is located on the X chromosome.
This defective allele is found on the X chromosome; females have two X chromosomes, while males have one.
A female with this genetic disorder has a one hundred percent chance of passing on the defective allele to her offspring.
In conclusion, a female offspring of the cross has a 100% chance of having a recessive allele for Duchenne muscular dystrophy disorder.
Thus, the correct option is 4.

Answer:
the answer is D
Explanation:
Heat energy is transferred through solids, liquids, and gases. How is heat transferred throughout the world’s oceans?
A) The warmed atmosphere transfers energy as heat to the rivers and the energy is distributed by conduction to oceans.
B) Sunlight penetrates the ocean’s waters, evenly distributing energy as heat from the surface to the ocean floor.
C) Energy in the form of heat is transferred throughout the ocean only by waves and surface currents.
D) Convection currents are driven by sunlight warming surface waters, which flow throughout the oceans, distributing energy as heat.
Answer:
C) Energy in the form of heat is transferred throughout the ocean only by waves and surface currents.
Explanation:
Heat is transferred between the surface of a sea or ocean and the atmosphere through radiation, convection, and turbulent heat exchange and by means of the evaporation of water and condensation of water vapor above the sea or ocean.
If it's not C then my best guess would be D. This one is kind of tricky!!

Stimulation of the insulin receptor by ligand binding and autophosphorylation eventually leads to the activation of glycogen synthase and the translocation of glucose transporters to the plasma membrane. One strategy for treating diabetes is to develop drugs that act as inhibitors of the phosphatase enzymes that remove phosphate groups from the phosphorylated tyrosines on the insulin receptor. Why might this be an effective treatment for diabetes
