wait i may be dum but it sounds like your stating something rather then asking.. could you maybe reword the question?
The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light and
dark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
C)
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.
Answers
Answer:
A,B,C,F
Explanation:
A, B, C and D all of these statements support the idea that natural selection changes populations, not individuals.
What is natural selection?Natural selection is a process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. This leads to changes in the genetic makeup of a population over time, as advantageous traits become more common and less advantageous traits become less common.
Natural selection is driven by environmental pressures, such as predators, competition for resources, or changes in climate. It is a key mechanism of evolution, and helps to explain the diversity of life on Earth and the ways in which different species have adapted to their environments.

Answers
Answer:
selective breeding............
Genetic engineering allows the modification in the DNA of an organism. To obtain a disease free plant, genetic engineering is carried out. Thus, option c is the correct answer.
What is genetic engineering?Genetic engineering is a tool used in biotechnology to bring modifications or alterations in the genetic material - DNA of an organism. It modifies the DNA through addition of a gene segment or deletion of a gene.
In genetic engineering process, a specific gene of interest or the desired genetic sequence is selected. It then inserted into a cloning vector to allow its replication in the host gene. The so called 'recombinant' then formed is inserted into the host through various insertion techniques.
Genetic engineering thus allows the selection of a disease free plant, pest resistance or temperature resistant plant. A new variety of the plant can be obtained through genetic engineering.
The genome of an organism can thus be edited where the unhealthy genes can be eliminated through genetic engineering.

Early genetic manipulation of petunias included an attempt to engineer dark purple petals. To this end, extra copies of the gene that causes purple pigment was engineered to be produced in the petunia. However, to the surprise of many, the plants carrying the extra copies of the purple gene were completely white or only had patches of color. Molecular analysis revealed that the purple gene was reduced 50-fold in the engineered plants compared to wild type. Provide a possible explanation how this occurred. Also, provide a possible experiment that may overcome this setback
Answers
Answer:
The altered pigmentation in transgenic petunia plants is caused by the RNA interference (RNAi) mechanism
Explanation:
The RNA interference mechanism is a naturally occurring mechanism by which single-stranded RNA molecules can bind to complementary mRNAs in order to inhibit gene expression, blocking translation and leading to mRNA degradation. The example above described is a classical genetic experiment (Napoli et al. 1990 ) that showed the existence of the RNAi pathway by the overexpression of a chimeric chalcone synthase (CHS) gene in pigmented petunia flowers, which blocked anthocyanin biosynthesis. In this experiment, irregularly bicolored/white flowers in transgenic petunias containing exogenous pigmentation genes were developed. The co‑suppression of gene expression was produced by the high-copy-number transcription of the CHS transgene, showing the existence of an undescribed RNAi silencing mechanism. Somatic reversion of the altered phenotype can be achieved by restoring the normal mRNA levels for these pigmentation genes, e.g., by a progeny testing in order to eliminate transgenic CHS expression.

What the consequences would be if the entire water surface was covered with water lilies
Answers
Answer: There can be a ton of damage done if water lilies overgrow.
Explanation:
Water lilies protect the organisms under the body of water and provide shade to the plants and organisms underneath. These are very important for organisms, as they also provide a place to rest. But if the entire water surface were to be covered with water lilies, this would be a major problem, because sunlight would have no way of reaching below the surface, and this would decrease oxygen levels for plants and organisms. Without air and sunlight, plants will start to die and organisms of the body of water will also start to die because of no air to breathe. Also, overgrowth of water lilies causes water stagnation and leads to excessive algae blooms. The stagnant water attracts insects like mosquitoes, cockroaches, termites, and more pests which can harm plants and organisms.

Answers
Explanation:
Halotolerant is the ability of the organism to grow at the higher concentration of salt than the required concentration for its growth.
As we know Mannitol salt is used as selective medium for isolation of pathogenic bacteria. The medium has mannitol salt, phenol red indicator, 7.5% sodium chloride. This high salt concentration inhibits the growth of most bacteria.
The interpretations and the conclusion regarding to the given situation should be explained below.
What is Halotolerant?It is the capability of the organism for growing at a higher concentration of salt as compared to the concentration with respect to the growth. Since Mannitol salt should be applied as the selective medium for isolation of pathogenic bacteria. The medium contained the mannitol salt, phenol red indicator, 7.5% sodium chloride.

why is it difficult for scientists to study the mechanism of evolution
Answers
Answer:
Because evolution is not a simple process and it is hard to accurately determine how a species evolved or what the species evolved from.
Mode of Action of the Herbicide DCMU When chloroplasts are treated with 3-(3,4- dichlorophenyl)-1,1-dimethylurea (DCMU, or diuron), a potent herbicide, O2 evolution and photophosphorylation cease. Oxygen evolution, but not photophosphorylation, can be restored by addition of an external electron acceptor, or Hill reagent. How does DCMU act as a weed killer
Answers
Answer:
It acts as a weed killer by blocking photosynthesis
Explanation:
Photosynthesis is important to plants because it is their principal form of energy.
When DCMU is introduced to weeds, what it does is to block or slow down the process of photosynthesis. Carbon dioxide fixation is slowed down causing weeds to die off. DCMU strongly slows down photosystem II. When this is done, lipid and protein membranes would get destroyed and the weed cells would begin to dry and shed off
