Answer:

B. Its innermost energy level.

Explanation:

Carbon has six electrons, four of which are located in its valence shell. Thus, the tetravalent carbon makes four covalent bonds to achieve its chemical stability. These connections are made at your innermost energy level.

It can bond with other carbon atoms, chaining together, to form numerous types of chains. The carbon atom binds to hydrogen and other common elements in organic compounds such as oxygen (O), nitrogen (N), sulfur (S), halogens (Cl, Br, F, I), etc.

The diagram shows three steps in the carbon cycle.
Bumek [7]

Answer:

A. Cellular respiration

C. Photosynthesis

Explanation:

There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.

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.

How many high-phosphoryl-transfer-potential molecules are required to synthesize phosphatidylethanolamine from ethanolamine and
valkas [14]

Answer: 3(three)

Explanation:

In the biosynthesis of phosphatidylethanolamine from ethanolamine and triglyceride, 3 high energy molecules are used in the first and second step.

The first steps occur in the cytosol, where ethanolamine is phosphorlated with ATP to give phosphoethanolamine and ADP by the enzyme ethanolamine kinases, and in the next reaction which is the rate-limiting step, phosphoethanolamine react with cytidine triphosphate (CTP) to form cytidine diphosphoethanolamine. In this reaction two molecules of phosphate group is given off.

The third step occurs in the endoplasmic reticulum CDP-ethanolamine react with diacylglycerol to form phosphatidylethanolamine.

The answer is Three high energy molecules. One molecule of ATP to form phosphorylethanolamine and two molecules of ATP to regenerate CTP from CMP.
