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

Answer:

The pea plant would produce 1 WW, 2 Wp, and 1 pp. There would be 3 white flowers, and 1 purple.

Explanation:

Answer:

The correct answer is d) photosynthesis

Explanation:

Photosynthesis is the process by which plants transform inorganic matter from their external environment into organic matter that they will use for their growth and development. It basically consists of the production of sugars from C02 (carbon dioxide) in the air, minerals and water with the help of sunlight. In this reaction, oxygen molecules are released and carbohydrates are fixed in the plant. Plants absorb sunlight through a pigment called chlorophyll. Not only can plants fix CO2, so do certain bacteria and green algae. Photosynthesis is conditioned by internal plant factors and external or environmental factors.

Symbiosis is when two organisms help each other, usually benifitting one if not both of the said orgaisms.

Answer:

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

Answer:

it is 300kj

Explanation:

The energy that will be acquired by the cheetah when it consumes the zebra is 30,000 kJ.

The law of conservation of energy states that energy can neither be created nor destroyed but can be transformed from one form to another.

The energy of the grass will be transferred to the zebra when the zebra consumes the grass. Also the total energy of the zebra will be transferred to the cheetah when it consumes the zebra.

Thus, the energy that will be acquired by the cheetah when it consumes the zebra is 30,000 kJ.

Answer:

b. Each band represents a different-sized subunit of a multimeric protein.

Explanation:

SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.

The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.

SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be.  The speed of displacement in the electromagnetic field is inversely proportional to the protein size.

Answer:

If the insulating material covered around the can.

Explanation:

If the can is covered with thick layer of insulating material then it can't be attracted by the magnet because there is a gap between magnet and metal. Can is a metal which is attracted by the magnets just like iron and copper etc. If there is no insulating material between magnet and can, then it must be attracted by the magnet so that's why we can say that insulating material is responsible for the no attachment of magnet to the can.

Answer:

Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range.

Answer:

Explanation:

Contraction of a disease by the environment, the environment is said to influence something certain traits either by amplifying them or prevent them from being expressed. Some disease tends to strive in environment that is favorable while some disease don't find expression where the environment is not conducive even though they are presents in the gene of the individual. Environment could include family, area where the individual lives, food, peer

While Contraction of disease that are heredity/genetic and having pathogenic pathways is high this is because any disease that is hereditary can be passed to successive generation through the inheritance of such gene from the parents this increase the likelihood of reoccurrence of such disease in a family where the parents has it.

Answer:

quantitative data

"quantitative" refers to the amount of something, so if it has something to do with numbers, It's quantitative.

There were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

There are both types of data, such as the quantitative data, in which the quantity can be measured, such as the 12 elephants and the 141 beats, and the qualitative data, which can't be measured but is widely seen in the genetics, such as the coat color of the animals, the skin color of the human, etc.

Hence, there were twelve elephants in the clearing, which is quantitative data, while the pulse rate of 141 beats per minute is also quantitative data, but the orange fur with black stripes is qualitative data.

Answer:

Traits are coded for in DNA, specifically in genes.

Explanation:

DNA, as you probably already know, is made up of long sequences of nucleotides of A's, T's, C's, and G's. When transcripted into mRNA and translated into proteins in ribosomes, the order of these nucleotides signal which amino acids to produce for the protein. Proteins are extremely important and have many roles throughout the body, which means they actualize the code of DNA into physical traits. I hope this helped.
