The correct answer is option A ,  C and D

The earths material is recycled and this can be visualized from the different chain cycles such as nitrogen cycle, carbon cycle , sulphur cycle, water cycle etc. These basic components which constitute all the matter existing on earth are continuously recycled and reused. Likewise the energy obtained from sun is neither created nor destroyed; it is only converted from one form of energy to the other form. Such as heat energy obtained from sun is converted into kinetic energy when it converts water into water vapor.

The almost pure cellulose obtained from the seed threads of Gossypium (cotton) is tough, fibrous, and completely insoluble in wa
olga55 [171]

Answer:

Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.

Explanation:

Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.

Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer

GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.

Why is milk used as a first-aid remedy for someone who has swallowed a heavy-metal poison?
klio [65]
Human trials have indicated an inverse relationship between blood lead level and calcium intake. While milk isn’t an antidote to let’s say, lead poisoning, the dietary calcium inhibits the lead absorption. This sort of poisoning is incredibly dangerous to the systems of the human body, and the ingredients within the milk help to defend against it. The purpose of the milk is to dilute the ingested poison.

Basophils of the blood help to get defensive leukocytes to the site quickly by releasing an anticoagulant called __________ and
Alex

Answer:

Basophils of the blood help to get defensive leukocytes to the site quickly by releasing an anticoagulant called ___heparin_______ and a vasodilator called _____histamine_____

Explanation:

Basophils are a type of white blood cell containing specific granules that release histamine (vasodilator) and heparin (a substance with anticoagulant action) and azurophilic granules that contain lysosomes. They are important in allergic and anaphylactic processes.

Which of the following statements is correct relative to solar cheilosis (SC)?<br> RSE PDFS
Kay [80]

Answer:

The correct answer is "all of the above".

Explanation:

The missing options of this question are:

A. The major etiologic factor associated with SC is ultraviolet radiation, principally UV-B.

B. Factors predisposing to SC include skin phenotype, age, male sex, outdoor occupation, rural living, and host immune status.

C. AK and SC serve as clinical dose-meters for chronic UVR exposure.

D. All of the above.

The correct answer is option D. "All of the above".

Solar cheilosis (SC) is a type of precancer of the lower lip, induced by ultraviolet light exposure, particularly by the exposure of UV-B from sunlight. However, UV-B exposure is not the only cause of SC, there are different factor that predispose to the development of this disease, including skin phenotype, age, male sex, outdoor occupation, rural living, and host immune status. Particularly because people with an outdoor occupation is  more expose to sunlight and people with an detrimental immunological condition cannot fight SC as easy as a healthy person. According to the scientific article "Epidemiology of actinic keratoses and squamous cell carcinoma" by Salasche SJ., Actinic keratosis (AK) and SC serve as clinical dose-meters for chronic UVR exposure
