Explanation

 A glycosidic bond is a covalent bond that connects two monosaccharides, forming disaccharides or polysaccharides. 

Ester bond: Ester bonds are found in lipids, not carbohydrates.

Phosphodiester bond: Phosphodiester bonds are found in nucleic acids (like DNA and RNA), not carbohydrates. 

Peptide bond: Peptide bonds are found in proteins, not carbohydrates. 

Explanation

Monosaccharides are the building blocks of disaccharides (such as sucrose, lactose, and maltose) and polysaccharides (such as cellulose and starch).

A glycosidic bond is a covalent bond that connects two monosaccharides to form a disaccharide or polysaccharide. 

Explanation

Chlorophyll a primarily absorbs light in the blue-violet and red regions of the visible light spectrum, with peak absorption around 430–470 nanometers (nm and 660–670 nm, respectively.

The molecule shows poor absorption in the green region, which is why plants typically appear green.

Explanation

The central metal atom in chlorophyll is Magnesium. 

Chlorophyll, the green pigment in plants, has a magnesium atom at its core, which is crucial for its function in photosynthesis. 

Explanation

The functional group in chlorophyll is a porphyrin ring with a central magnesium ion (Mg²⁺).

This large ring structure, specifically a chlorin ring, which is a reduced porphyrin,

It is responsible for absorbing light energy during the process of photosynthesis. 

Explanation

Yesterday was Friday.

Therefore, today is Saturday (the day after Friday).

Tomorrow will be Sunday (the day after Saturday).

The day after tomorrow will be Monday: (the day after Sunday).

Explanation

According to Coulomb’s Law, force is inversely proportional to the square of distance: F∝ 1/r².

So, if distance is doubled, force becomes 1/(2)² = 1/2.

Explanation

If both force and displacement are doubled, work and energy become four times their original value

This is because work is the product of force and displacement, so if each is multiplied by two, the result is multiplied by 2x2, or four. 

Explanation

- The electron transport chain (ETC) is embedded in the inner mitochondrial membrane.  

- The folds of the inner membrane are called cristae, which increase surface area.  

- ETC is the final stage of aerobic respiration, producing the most ATP.

Explanation

After implantation, the primary hormone secreted is progesterone. 

When a fertilized egg implants in the uterine lining, the trophoblast cells of the embryo secrete a hormone called human chorionic gonadotropin (hCG).

hCG signals the corpus luteum (the structure that produces progesterone before ovulation) to continue producing progesterone,

This is crucial for maintaining the pregnancy.

Progesterone levels rise significantly after implantation.
