A new homeowner purchased several hydrangea plants that were full of deep blue-
violet blooms. When she planted them at her home, however, only the plants near her
house bloomed a blue-violet color. Those down the driveway were a vibrant pink.
What was the probable cause of the blossom color variation?

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.

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.

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.

The answer is D. Mutualism

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.

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.

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.

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.

The two phases of the respiratory movement of man is inspiration ( or inhalation) and expiration (or exhalation). The phases of the respiratory movement of men is the same in fish because they also inhale and exhale.

What is inspiration (inhalation ) ?

Inspiration (inhalation) is the process of taking air into the lungs. It is the active phase of ventilation because it is the result of muscle contraction.

What is expiration (exhalation)?

Expiration (exhalation) is the process of letting air out of the lungs during the breathing cycle.

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

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.

The test statistic for this hypothesis test is - 3.68.

Explanation:

A test statistic is a random variable that is calculated from sample data and used in a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis.

Sample proportion = 38/50

= 0.76

Hence,
