Monocots

1. Embryo has single cotyledon

2. Flower parts in multiples of threes

3.Major leaf veins are parallel.

4. Roots are adventitious

5. Stem vascular bundles scattered

6. Pollen with single furrow or pore.

7. Secondary growth absent.

Dicots

1. Embryo with two cotyledon

2. Flower parts are in multiples of four or five.

3. Major leaf veins reticulated.

4. Roots develop from radicle.

5. Stem vascular bundles are in a ring.

 6. Pollen with three furrows or pores.

7. Secondary growth often present.

In a monocot, the vascular system is intertwined and scattered throughout the stem of the plant. In a dicot, the vascular system is arranged in rings rather than throughout the plant.

3. mRNA

4. Transcription

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

9. Translation

10. anti-codons

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific  tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.

Igoryamba

Answer:

Increase with a stimulant and decrease with a depressant

Explanation:

Stimulants and depressants are observed using various organisms. The way a stimulant works is by increasing the dopamine levels in the body. This in turn causes increased heart rate as would be seen in the chick embryo heart. On the other hand a depressant would lower dopamine levels. This would reduce the neurotransmitter and cause the heart rate to slow down.

Which is the difference between an antibiotic and an antiviral?
jeyben [28]

Answer:

There are no options in this question, the options are as follows:

A. Antibiotics build up immunity, and antivirals increase white blood cells.

B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.

C. Antibiotics are in liquid form, and antivirals are in mist form.

D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.

The answer is D

Explanation:

Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.

According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.
