Drag each of the following organs to the appropriate organ system. Labels can be used more than once if the organ is a major par

Sergio039 [100]

Answer:

Nervous-brain as the components of the central nervous system,together with the spinal cord.

Digestive-Stomach as the components of the upper digestive or alimentary canal.It is for temporary storage and digestion of foods.

Small intestine where final digestion and absorption takes place

Respiratory-Lungs.-paired in mammals is for exchange of gases.

-Trachea as part of the upper respiratory system,conducts airways to the lungs

Reproductive-Ovary female reproductive organ for ova production

Urinary-Ureter for conducting urine to the bladder from the kidney to penis and orifice in females to the exterior.

Cardiovascular( the heart and the blood vessels)- heart the pumping organ into the blood vessels.

Endocrine-Thyroid gland for secretions of thyroid hormones -T3 and T4.

Pancreas for insulin and glucagon productions,and helps in digestion,

Integumentary-Skin,for protection of the body.

Lymphatic-Spleen.This forms the lymphatic system for formation of un reabsorbed tissue fluids the lymph.

Skeletal-Bones for support and rigidity of the body,by attaching to the bones,

Muscular system-muscles for stability of the body in mammals.

How are cancer therapies tailored to nucleotide synthesis -explain using the example of fluorouracil and methotrexate.

nika2105 [10]

Answer:

By preventing the synthesis of DNA halting cell growth.

Explanation:

Fluorouracil and methotraxate prevent the synthesis of the neucleoside Thymidine thus preventing DNA replication and elongation. Methotraxate has a structure analogous to Folic acid which is important for thymidine synthesis. Thus, it acts as a competitive inhibitor on dihdrofolate reductase an enzyme that is essential for tetrahydrofolate formation, a folic acid derivative.

Fluorouracil acts by inhibiting thymidylate synthase which catalyses an essential step in Thymidine synthesis.

In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly.

musickatia [10]

In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.

<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>

Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.

The following components could be found in a normal prokaryotic cell:

The membrane enclosing and guarding the cell is known as the cell wall.

All of the cell's internal components, excluding the nucleus, are called cytoplasm.

Some prokaryotic cells have filaments made of proteins called flagella and pili.

A nucleoid is a cell structure that resembles a nucleus and contains genetic material.

A plasmid is a little DNA molecule with independent reproduction.

<h3>Eukaryotes</h3>

Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.
