1. Which type of reaction has water in its products?
a. Hydrolysis
b. Dehydration synthesis

2. What type of reaction uses water as a reactant?
a. Hydrolysis
b. Dehydration synthesis

Answers

Answer:

1. b. Dehydration synthesis

2. a. Hydrolysis

Explanation:

Hydrolysis is the process where water is used to break chemical bonds. Dehydration synthesis is the reverse reaction, where a bond is formed resulting in the loss of water from the molecule, so a water molecule is generated as a product.

That means that dehydration synthesis produces water, and hydrolysis uses water.

Answer:

b. Dehydration synthesis gives out water as a product.

a. Hydrolysis reaction uses water as a reactant.

Explanation:

b. Dehydration synthesis can be defined as, formation of larger molecule from small reactant, followed by loss of water from the reaction.

They are also called condensation reactions.

a. Explanation: Hydrolysis, it is the reaction in which compound is interacted with water which results in the degradation of that particular compound.

Hydo means water, lysis means to dissolve or breakdown.

Answers

Answer:

DNA replicates

Explanation:

S phase (Synthesis Phase) During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids, the synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated. Throughout interphase, nuclear DNA remains in a semi-condensed chromatin configuration

What happens to air pressure as the altitude increases?
O It gets lower
o It gets higher
0 It stays the same

Answers

Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

Explanation:

As altitude rises, air pressure drops.

The measurement of 45 N represents the magnitude of force in the photograph.

What is force?

Force is defined as a cause which is capable of changing the motion of an object. It causes an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as a direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object while torque produces change in rotational speed of an object.
