Enterobacter, Klebsiella, and Escherichia coli.

Coliform bacteria is known to be a gram negative bacteria with rod-shaped and can fermantlactose with the production of acid and gas when incubated at 35-370C. Thus, IMViC are normally used in the identification of genera of Enterobacteriaceae which is responsible for intestinal infections. However, IMVic test will indicate the presence of Enterobacter, Klebsiella, and Escherichia coli.

Answer:

If the IMVic test detects the presence of E. coli it means that the water is contaminated with faecal coliforms.

Explanation:

The IMVic test is a test that can be used to discover contaminants in water. The water may be contaminated by fecal coliforms or substances from plants and soil. These substances are associated with the presence of some bacteria, which is why the IMCic test is so efficient.

The IMVic test is able to detect the presence of Klebsiella, Enterobacter and Escherichia coli bacteria. If after the application of the test, the presence of E. coli in the water is detected, it means that the water is contaminated with faecal coliforms. If the presence of Klebsiella or Enterobacter is detected it means that the water is contaminated with substances of plant origin or soil particles.

Which statements could be categorized in the "Asexual" section of the Venn diagram? Check all that apply
EastWind [94]

Answer:

The right answer are : mitosis, diploid cells, and identical DNA.

Explanation:

The answers "two cell divisions" and "gametes" refers to a division by meiosis which is a sexual reproduction.

Asexual reproduction or asexual reproduction is a mode of reproduction, which - as opposed to sexual reproduction - corresponds to the capacity of living organisms to multiply alone, without a partner, without involving the fusion of two gametes of opposite sexes. Asexual reproduction is observed in multicellular (animal and plant) and unicellular organisms. In botany, the term often used for the asexual multiplication of plants is vegetative multiplication. In all cases of asexual reproduction, the result is identical to the mother.

In the u.s., about what percentage of all food expenditures is now accounted for by meals eaten out?
quester [9]
<span>Eating away from home is playing an increasing large role in the diet and the household budgets of American families. Back in 1970 approximately 26 percent of all food spending was on food away from home; by 2012, that amount had risen to 43 percent. The increase can be attributed to a greater percentage of women employed outside the home, more two-earner households with the resulting higher incomes, as well as more affordable and convenient fast food outlets. The downfall of this statistic is the contribution all that fast food makes to higher levels of obesity and lower dietary nutritional quality.</span>

19. Which of the following is the best strategy to control wheat rust?
valentinak56 [21]

Answer:

B. Fungicides to treat affected crops and planting rust-resistant varieties

Explanation:

Leaf rust is a disease caused by the fungus <em>Puccinia triticina</em> which affects leaves, stems and grains in wheat and related cereals (i.e., barley and rye). This disease is known to affect crops in moist conditions. Leaf rust disease is spread through fungi spores from infected wheat plants to healthy plants. Recently, leaf rust-resistant varieties have been developed by crop improvement programs aimed at introducing leaf rust-resistant (lr) genes involved in resistance against this important crop disease. Moreover, there are different types of fungicides (e.g., Prothioconazole and Tebuconazole) used for chemical control of this disease.
