Organisms that utilize inorganic molecules (such as hydrogen sulfide), carbon dioxide and water to form organic molecules in the
GarryVolchara [31]

Answer: b. chemoautotrophs

Explanation: chemoautotrophs are organisms that obtain energy, molecules, water by the oxidation of electron donors in their environments. Chemoautotrophs are able to synthesize their own organic molecules from inorganic sources. They are different from phototrophs who requires sunlight to make their own food

Compare the roles of the phospholipid bilayer in passive and active transport.
morpeh [17]

Answer:

Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.

Explanation:

Molecules can move in 2 ways: passive and active.

The only difference is the energy that is needed to do the movement.

In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.

How does replication of the lagging strand of DNA compare with replication of the leading strand?
Natali5045456 [20]

Answer: The correct answer is- B) Okazaki fragments are made on the lagging strand but not on the leading strand.

DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called DNA polymerase.

The strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. DNA is synthesised in 5' to 3' direction.

Leading strand ( whose template strand is 3' to 5') is synthesized in continuous manner as DNA polymerase moves along the direction of replication folk.

Whereas lagging strand ( whose template strand is 5' to 3') is synthesized in a discontinuous manner as it requires multiple primers to synthesise the DNA. It generates small fragments of DNA called okazaki fragments.
