19. Which of the following is the best strategy to control wheat rust?
O A. Invasive insect species to attack rust
B. Fungicides to treat affected crops and planting rust-resistant varieties
C. Citrus greening to prevent the spread of rust
O D. Insulation using green roofs to limit rust

Answers

Answer:

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

Explanation:

Leaf rust is a disease caused by the fungus Puccinia triticina 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.

Rosalind Franklin's X-ray studies. This indicated that
DNA was
A. a triple helix with intertwined bases.
B. a double helix with bases outside the helix.
a. a double helix with bases inside the helix.
D. a single linear molecule of bases held together by
sugar-phosphate bonds.

Answers

Answer:

The right answer is the third statement.

--> A double helix with bases inside the helix.

This indicated that DNA was a double helix, with bases inside the helix. The correct option is c.

What is Watson and Crick's DNA model?

Watson and Crick theorized that DNA is a double helix made up of two long helical strands twisted together.

In "Genetic Implications," Watson and Crick postulate that the replication of deoxyribonucleic acid, or DNA, may have a structural foundation. Scientists had just recently concluded that DNA contained genes, which were known to contain information that dictated an organism's identity when Watson and Crick proposed their theory of DNA replication.

In their model, each DNA strand was made up of discrete elements called bases, and the bases on one DNA strand matched the bases on the other.

Therefore, the correct option is c. a double helix with bases inside the helix.

Morphine 4mg IV push is ordered. The vial states 10mg/mL. How many mL will you give?

Answers

Answer:

If a vial of morphine has 10 mg/mL, and a dose of 4 mg is required to be administered intravenously, 04 mL must be administered to fulfill the indication.

Explanation:

Morphine is a drug, an opioid derivative, with a potent analgesic and sedative effect. Its use is intended for acute or chronic severe pain, mainly related to cardiovascular disease, cancer or severe trauma.

One vial of morphine vial has a concentration of 10 mg/mL, so if 4 mg is required, a simple calculation must be made:

Morphine: 10 mg ------------ 1 mL

Dose:          4 mg ------------ X

X = (4 x 1)/ 10

X = 4/10

X = 0.4 mL

To administer 4 mg of intravenous morphine, 0.4 mL of the injection should be used.
