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.

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.

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.

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.

Answer:

Mostly glucose

Explanation:

Answer:

Different Cell Types Require Different Fuel Molecules. Red blood cells rely on glucose for energy and convert glucose to lactate. The brain uses glucose and ketone bodies for energy. Muscle cells use fatty acids, glucose, and amino acids as energy sources.

Answer: 20. A 21. B 22. A=2, B=3 23. A=4, B=3 25. B

Explanation: A has H2O (water). B has a hydrogen ion, so acidic.

In B H2CO3 is carbonic acid

The loss of hydrogen atoms leads to the formation of acids and the hydroxide forms bases. Equation A represents the formation of water, and equation B shows the acidic solution.

Chemical reactions are said to be involved in producing products from the reactants that undergo chemical changes. Water is formed by reacting the four hydrogens and one oxygen molecule as:

2H₂ + O₂ → 2H₂O

H₂CO₃ → H⁺ + HCO₃

Here, carbonic acid dissociates a proton that makes the solution acidic.

Therefore, the first equation represents the formation of water by oxygen and hydrogen atoms.

Answer:

answer is on the pic

Explanation:

may be this is helpful!

Answer:

A

Explanation:

The correct answer would be that Watson and Crick's structure of DNA was not done until 1953.

The fact that chromosomes are condensed together in the nucleus, are not distinguishable during interphase, and a method had not yet been devised to halt mitosis at metaphase could have plausibly delayed the successful counting of human chromosomes.

On the other hand, the discovery of the structure of the DNA could not have delayed the study of chromosomes because the DNA structure has no bearing on the karyotyping of chromosomes.

The chromosomes of organisms are best studied using a relevant microscope during metaphase when they would have fully decondensed and align at the equator of the cell or the metaphase plate. At the interphase phase of the cell cycle, chromosomes are full condensed under the view of the microscope.

The correct option is, therefore, A.

Answer:

Mutation

Explanation:

Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.

A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

The given question is incomplete as it lack the options, however, answer can be given by the provided information.

Answer:

The correct answer is - 3:1 ratio.

Explanation:

In the question it is given that both male and female both are heterozygous for the trait, let assume dominant allele A and recessive allele a so the the gene for the both male and female is Aa.

Punnett square for the cross between both:

gametes: A, a and A, a.

A a

A AA Aa

a Aa aa

here two out of four are heterozygous dominant and one is dominant and one is recessive.

thus, 3 out of 4 are dominant and one out 4 are recessive.

thus, the answer is 3:1 ratio

Explanation:

The thyroid hormones are produced by the thyroid glands and they're the triiodothyronine and the thyroxine. The thyroid hormones are required in metabolism regulation, performs digestive functions, controls the muscle of the heart, and develops the brain.

If thyroid hormones are not released, you can regulate body temperature by shivering and which requires a greater use of oxygen.
