To solve this we must be knowing each and every concept related to population. Therefore, the correct option is option D among all the given options.
Population is the total number of people inhabiting a space, which is always changing due to additions and deletions. The availability of food, the impact of illnesses, and other environmental conditions all have an impact on the growth of a human population, just like they do for any other biological species.
Social norms controlling reproduction and technical advancements, particularly in public health and medicine which have decreased mortality and increased life expectancy, have an additional impact on human populations. The increasing frequency of purple-flowered plants shows that the population is evolving.
Therefore, the correct option is option D.

The answer is D. The increasing frequency of purple-flowered plants shows that the population is evolving.
Answer:
The high end cost of professionals and litigation matter caused the faliure of Superfund
Explanation:
Super fund program was initiated by the united States to clean most toxic and contaminated places in 1980.
It strengthened the EPA by providing them power to identify organisation responsible for producing noxious hazards nationwide. Till today 1300 such sites lie on the priority list of the programme.
The programe was a shortcut strategy to clean up the harmful sites by billions of funding. But cases such as lake canal where the clean up programme even after 15 years is slow due to litigation and high cost issues makes the consequence dicey.
Most of the cost estimated for any cleaning any hazardous sites consists of made administrative fees and lawyers salary apart from the actual cost of cleaning which caused the failure of Superfund in terms of its implementation
Superfund is a program from EPA (Environmental Protection Agency) that helps in cleaning some of the US’s most contaminated land and responding to environmental emergencies, oil spills and natural disasters. One of its targets this coming June 8 is the Portland Harbor.
Answer:
Well for this question it is necessary that you upload the image.
Although I would tell you that whenever mRNA is affected, protein synthesis is one of the most important and relevant causes in cell life.
Explanation:
Another fact to add is that according to the protein that is selected, determine the vitality or not of the cell.
In the inoculation of the toxin if the synthesis of a protein that makes up the membrane structure, or of the fundamental structures for vitality, is affected, the cell will go into apoptosis or die.
On the other hand, if the protein synthesis is referred to some enzyme, or a second protective messenger, the cell continues with its vitality.
Answer:
Translation can be described as a process in which proteins are synthesized.
Differences between the prokaryotic and eukaryotic translation are:
B. a perfect pesticide.
C. subject to biological magnification.
D. deadly to herbivores.
Answer:
C. subject to biological magnification.
Explanation:
DDT is an insecticide that exhibits slow metabolism and excretion. The slow breakdown of DDT causes it to accumulate in fat tissues of organisms. Biological magnification refers to the process of increased concentration of toxic chemicals in the tissues of living beings of higher tropic levels. The accumulated higher concentration of DDT poses harmful effects on the health of top consumers.
Answer:
By the observation, the rod shape violet-colored bacteria could be a Gram-positive bacillus which is Lactobacillus spp. in curd.
Explanation:
Gram-stain is a staining method to isolate and study the Gram-positive or Gram-negative bacteria with the help of the crystal violet dye. Crystal violet dye stains both Gram-positive and Gram-negative bacteria in purple stain. After decolorization, Gram-negative bacteria appears to be pink in color, however,Gram-positive bacteria remain purple.
According to bacteria structure, they term as bacillus (rod), strepto (clusters or threads) or Diplo (in pairs).
Thus, according to the observation, the rod shape violet colored bacteria are Gram-positive bacillus which is Lactobacillus spp. in curd.
Answer: the right ventricle
Explanation:
The pulmonary trunk originates from the right ventricle through which deoxygenated blood is pumped into the lungs.
The pulmonary trunk divides into right and left pulmonary artery which carries blood to their respective lungs.
Blood flow into the pulmonary trunk is regulated by the semilunar valve.
The right ventricle of the heart exits into the pulmonary trunk. This process is part of our body's pulmonary circulation, responsible for oxygenating blood.
The chamber of the heart that exits into the pulmonary trunk is the right ventricle. In the human heart, blood flows from the right atrium into the right ventricle after which it's pumped out of the heart into the pulmonary trunk. This blood then splits between the two pulmonary arteries that carry it to the lungs where it gets oxygenated. This process is part of the pulmonary circulation which is responsible for oxygenating blood. It's crucial for maintaining the body's overall oxygen levels and blood supply.
