Well, cray fish are omnivorous which means they eat animals too. Secondary consumers eat animals.

Cray fish are secondary consumers.

A client with cancer is diagnosed with typhitis. which emergency intervention would the nurse perform?

Gnesinka [82]

Typhitis, also called neutropenic enterocolitis, is an infection that often develops in cancer patients who undergo chemotherapy. In many cases, surgical intervention is required.

Without surgical intervention, the patient would be transferred to an ICU (Intensive Care Unit) for monitoring, and the nurse would perform some or all of these emergency actions:
1. Bowel rest and nasogastric suction,
2. Serial abdominal examinations,
3. Providing intravenous fluids, blood, and platelet transfusions when needed,
4. Using antibiotics to fight the infection, and obtaining cultures to determine if the antibiotic is working,
5. Not administering medication that could worsen the situation.

Template DNA 5' GATTCAGAGA 3'

Complemntary strand 3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

codes of mRNA GAU, UCA, UAG

Explanation:

5' GATTCAGAGA 3' is the example of DNA strand having the sequence.

The DNA strand is leading strand and is in 5' to 3' direction

the complementary DNA strand is formed in 3'to 5' direction as the strand of 5' to 3' acts as a tempelate for complementary strand.

During replication which is semiconservative a new template is formed by adding the nucleotides to the growing strand.

DNA synthesis always takes place in 5' to 3' direction.

5' GATTCAGAGA 3'

3' CTAAGTCTCT 5' Complemntary strand

Transcription is a process in which DNA sequence is transcribed into mRNA which carries codes for amino acids.

The 5' to 3' strand is called sense strand

3' to 5' strand is called antisense strand. mRNA is transcribed from antisense strand and is a copy of sense strand.

so the transcribed DNA strand as mRNA will be shown as:

3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

GAU codes for = Aspartate

UCA codes for = serine

GAG code for = glutamate (when due to mutation GAA will become GAG)

A will not code as it is not in triplets.

Type of nitrogenous base with a double ring found in DNA and RNA:

svet-max [94.6K]

Answer:

The correct answer will be option-B (purine).

Explanation:

Nucleic acid structure is made up of monomer unit called nucleotide. Each nucleotide is composed of a five-carbon sugar, a phosphate group and five types of nitrogenous bases.

The nitrogenous bases are categorized in two forms the purines (adenine and guanine ) and the pyrimidines (cytosine, thymine and uracil). The "purines" contain double rings in their structure due to which they appear larger in size than pyrimidines which are made up of single rings.

Thus, Option-B is the correct answer.

Which event takes place during normal fertilization?

Minchanka [31]

The event which takes place during normal fertilization is zygote formation.

<h3>Which event takes place during fertilization?</h3>

The major event which is characteristic of fertilization is zygote, otherwise termed cell formation in which case, the zygote is capable of undergoing cell division to form a new living cell. The fusion of two gametes necessary for fertilization kick-starts several reactions in the egg.
