The cells in this part of a plant form long, vertical tubes. What is the most
Soloha48 [4]

Answer:

The cells present in the stem are part of the xylem and phloem conductive tissues. They are characterized by being elongated and in tubular form because they transport the substances, the xylem transports  water and  inorganic mineral sales that the root absorbs from the soil. The phloem is responsible for transporting substances synthesized in photosynthesis.

Its tubular and elongated shape facilitates the transport of these substances

Kepler's second law using Mercury , which has an orbital period of about 0.24 and a semimajor axis of about 0.387 . Explain your
krok68 [10]

As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

<h3>What is Kepler's second law?</h3>

Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.

This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.

From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.

T \propto a^{3/2}

T = ka^{3/2}\\\\k = \frac{T}{a^{3/2}}

From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

Cyanide was used for treating cancer What might be the rationale behind this treatment?
enyata [817]

Answer:

   Cyanide is considered a specific neurotoxin and is often associated with high levels of cellular calcium and inhibition of antioxidants, leading to the formation of reactive oxygen species (ROS) and consequent lipid peroxidation.  But cyanide toxicity is mainly due to the iron (Fe (III) or Fe3 +) iron binding of the mitochondrial cytochrome oxidase enzyme of the electron transport chain. This enzyme mediates the transfer of electrons to molecular oxygen . By blocking this enzyme, the cell is unable to use oxygen and uses an anaerobic metabolism reducing pyruvate to lactic acid (lactic fermentation), which results in tissue anoxia and the rapid development of lactic acidosis. There is also a change in cell metabolism as there is a depletion in energy production.  So it causes cell death. This would be the mechanism to kill cancer cells. Although, cyanide cant be use to treat cancer because it kills all the cells (leading to death) and not only the cancer cells.

 Explanation:

   Some researchers founded that cyanide poison may have the role of being a powerful cancer fighter. It believes that they can relate the enzyme to cancer by looking for antibodies that can recognize a protein found only in certain cancers. The method would produce an agent that could potentially kill cancer cells and leave undamaged tissue healthy.

 As for the deadly nature of cyanide, scientists say the amount produced by this technique iwould be sufficient only to kill the cancer target cell by a combined enzyme and antibody molecule.  And a natural enzyme produced in the human liver could detoxify any cyanide that could escape the tumor. Although, cyanide is a drug that, even if ingest a small amount, could lead to death. Some studies are going on, but until now, theres no safety of taking cyanide to treat cancer cells.
