Answer:

B) Some of the product escaped as a vapor from the crucible.

Explanation:

Impurities and magnesium not reacting completely would not lead to less product necessarily. Nitrogen gas getting into the crucible would lead to a larger product mass.

Cell walls are impermeable to transport of most materials required for bacterial nutrition.
mezya [45]

The given statement is False.

The bacterial cells walls are composed of peptidoglycan, also known as murein. It comprises polysaccharide chains cross-linked by unusual peptides, involving D-amino acids. The bacterial cell walls are distinct from cell walls of fungi and plants that are made up of chitin and cellulose, respectively.

The cell walls in bacteria allow small molecules to pass through them freely, however, do not permit large molecules to pass through them, in this manner, it function as a coarse filter.

The main function of the cells wall is to sustain the shape of the cell and inhibit the cell from bursting due to osmotic pressure. The cell wall allows the components to pass, which are essential for bacterial nutrition.

What happens in the process of transcription
dolphi86 [110]
During the process of transcription, a portion of a DNA molecule is used to create a mRNA Molecule. DNA stores genetic information in the nucleus of your cells. When RNA molecules are produced it happens inside the nucleus. The RNA molecule can then leave the nucleus and travel to ribosomes which are located in the cytoplasm and attached to endoplasmic reticulum. The RNA will be used to create proteins molecules.

Systemic fungal infections (e.g. Candida and Cryptococcus) and tuberculosis (Mycobacterium) are on the rise. One of the reasons
miss Akunina [59]

Answer:

a) the molecules can be found in the picture below

b) (i) isocitrate lyase ( isocitrate to glyoxylate)

   (ii) malate synthase (glyoxylate to malate)

c)  Glyoxylate cycle do no exist in animals

Explanation:

b) in the glyoxylate cycle isocitrate lyase helps in conversion of  isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.

c)   Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.
