andrezito [222]

The most significant limitation to the clinical utility of anthracycline antineoplastic medicines, which include doxorubicin (adriamycin), daunorubicin, or epirubicin, is the danger of cardiotoxicity.

  • Nevertheless, these substances continue to rank among the most popular anticancer medications.
  • Although the oxidative stress-based concept involving intramyocardial formation of reactive oxygen species (ROS) has acquired the most respect, the molecular etiology of anthracycline cardiotoxicity is still quite debatable.
  • Through redox cycling of both their aglycones and anthracycline-iron complexes, anthracyclines may facilitate the generation of ROS.
  • Given the remarkable cardioprotective efficacy of dexrazoxane, this suggested mechanism has gained a lot of traction (ICRF-187).

What is Influenza?

  • It affects the lungs, nose, and throat.
  • High-risk groups include young children, elderly individuals, pregnant women, persons with chronic illnesses, and those with weakened immune systems.
  • Fever, chills, muscle pains, cough, congestion, runny nose, headaches, and exhaustion are some of the symptoms.
  • Rest and fluids are the main treatments for the flu because they allow the body to fight the illness on its own.
  • Anti-inflammatory painkillers sold over-the-counter may aid with symptoms. An yearly flu shot can lessen complications and aid in prevention.

(4.05 MC)What role does intraspecies competition play in natural selection?
jarptica [38.1K]
The correct answer is the first statement.
In intraspecies competition, there is a competition for recourses among the individuals from the same species. This is due to the limited availability of the recourses in the habitat. Only the fittest individuals will be able to gather enough recourses and survive.

Answer:

B. Cellulose

Explanation:

Polysaccharide are substances that contains many units of monomers called MONOSACCHARIDE. They are carbohydrate molecules consisting of very long chains of monosaccharides like glucose, galactose etc.

An example of molecule that forms from strong chains of polysaccharides is CELLULOSE, which consists of long chains of glucose units linked together by B-1,4-glycosidic bonds. Cellulose is the most abundant polysaccharide on Earth found in plant cell walls.

Is the arrangement of vascular bundles in the stem same for all plant species?Explain
blsea [12.9K]

\huge\boxed{\fcolorbox{red}{yellow}{Answer:- }}

No, the arrangement of vascular bundles in the stem same for all plant species.

<h2>☆ <u>In</u><u> </u><u> Monocot </u><u> </u><u>Stems</u></h2>

In monocots, xylem and phloem are organized in vascular bundles scattered throughout the stem. As the plant grows, monocot stems generate new vascular bundles for the new tissue. Monocot stems in general possess a simpler arrangement than that found in dicots.

<h2>☆ <u>In Dicots</u><u> </u><u>Stems</u></h2>

Within the class of plants known as dicots, herbaceous dicots and woody dicots have different arrangements of vascular tissues. In herbaceous dicots (plants, mostly annuals, with soft, non-woody stems), vascular tissue remains in discrete bundles even at maturity. In contrast, when mature woody dicots (plants, mostly perennials, with woody stems) reach maturity, the vascular bundles join together to form continuous rings around the interior of the stem.
