A MA has opened and used part of a new multidose vial. The MA should ______ the vial.

Answers

Answer 1

Answer: I think the MA should write the current date on the vial. It is important for the Ma to write the current date so as to keep track, and in case the MA requires to use it for reference when he/she wants to use it again. It is therefore important for an MA or nurses to label the vial by writing the date of use.

The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cells?endoplasmic reticulum
ribosomes
chloroplasts
lysosomes
peroxisomes
vesicles
large central vacuole
Golgi complex
cytoskeleton
mitochondria
cell wall

Answers

Large central vacuoles, chloroplasts, and cell walls are only found in plant cells.

Large central vacuoles store nutrients and waste products, but they also maintain the plants' structures.

Cell walls also maintain structure and rigidity.

Chloroplasts are used in the process of photosynthesis, which only occurs in plants.

Answer:

large central vacuole and cell wall

A - DNA as the inheritance materials B - RNA as the inheritance materials C - The formation of organic molecules, e.g. nucleic acids, from inorganic precursors

Answers

EXPLANATION:

There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).

Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).

The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.

Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.

A nucleotide is made up of 3 parts:

i) a nitrogenous base

ii) a five-carbon sugar

iii) at least one phosphate group.

Answer and Explanation:

DNA as the inheritance materials

Alfred Hershey and Martha Chase state the DNA as genetic material. DNA, or deoxyribonucleic acid, is the natural substance in humans and all other organisms. Every cell in a person's body contains the same DNA. Chromosomes are made up of nucleic acids and proteins and are called hereditary vehicles. ... DNA (deoxyribose nucleic acid) has been found to contain genetic material in all organisms.

RNA as the inheritance materials

• Wandell Stanley, in 1935 proved RNA as genetic material. RNA in humans does not act as genetic material but plays various other roles such as adapters, enzymes, helps in protein synthesis, etc. RNA functions as a messenger for the information to be transferred. The genetic material of organisms and many viruses is DNA. However, some viruses use an alternative type of nucleic acid, ribonucleic acid (RNA), as genetic material. ... RNA has excellent abilities as a genetic molecule; once has to continue the process of hereditary itself.

Nucleic acids

• First, nucleotide are activated, nucleic acid precursors. As such, they are needed for genome replication and transcription of genetic information into RNA. Second, the adenine nucleotide, ATP, is a universal energy currency. Nucleic acids are formed when nucleotide combine through phosphodiester bonds between 5 'and 3' carbon atoms.

Write a note on RNA polymerase

Answers

Answer:

Ther RNA polymerases (abbreviated as RNAPs or RNA pols), represent a group of conserved enzymes that synthesize RNA from DNA templates

Explanation:

These enzymes are used to synthesize different RNA species such as, amon others, messenger RNA (mRNA), transference RNA (tRNA), noncoding RNAs (ncRNAs), etc. During the gene transcription, the RNA pol is used to produce a mRNA molecule that subsequently is translated into protein

Answer: By definition, RNA polymerase or ribonucleic acid polymerase is a multi-subnunit enzyme that catalyze the process of transcription where an RNA polymer is synthesized from a DNA template.

Explanation:

RNA polymerase are highly conserved in evolution among eukaryotes, bacteria, archea and some viruses. Bacreria and archea has a single RNA. RNA polymerase are considered as molecular motors because of their stepwise movement on DNA. They are also central to biology information flow since they catalyzed templated polymerization reaction.

8. Some saliva was mixed with water and placed in a test-tube labelled A to which some boiled, cooled starch was added. Two other test-tube B and C were prepared as follows: Test-tube B-water and saliva Test-tube C water and starch. The three test-tube placed in water bah at 37°C and allowed to stand in the water for 5 minutes. A few drops were removed from each test-tube with a piece of glass tubing and tested with iodine solution and Benedict's solution. (a) Which of the test-tubes contained a solution that gave an orange precipitate with Benedict's solution? (1 mark)

Answers

Answer:

Explanation:

Solution:

Experiment:

Boiled potato is used here in mashed form and separated into three parts.

Separate them in test tube A, test tube B and test tube C.

In the test tube A, iodine is added.

In the test tube B, iodine is added and then saliva is introduced.

In test tube C, nothing is added and kept as the control set.

Observation:

The test tube A, the iodine solution changes the boiled potato to blue color.

In the test tube B, saliva is introduced and mixed with the sample after adding iodine.

As a result, the color change will be observed when starch will be broken down to simple sugars like maltose.

The blue color starts reducing in the test tube B as the saliva containing the salivary amylase starts acting on the starch.

Test tube C shows no color change.

Inference:

The change in the test tube containing saliva shows the effect of salivary enzymes like salivary amylase on the boiled starch present in potato.
