What does the measurement 45 N represent in the photograph?

Answers

Answer:

The magnitude(size) of a force

Explanation:

Apex

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.

Explain the process of DNA isolation.

Answers

Answer:

Lysis, precipitation and purification

Explanation:

DNA isolation is a molecular biology technique based on the extraction of DNA and subsequent purification to remove inhibitors that may hamper the process of amplification. DNA isolation consists of three steps:

1- Lysis: it consists of the mechanical disruption of the cell, where the nucleus is broken to release DNA. During this process, it is required to use enzymes and detergents such as Proteinase K

2- Precipitation: during this process, the DNA is precipitated by using alcohol and salt.  

3- Purification: this process removes the impurities from DNA. Extraction is carried out by washing DNA with ethanol and water.

Which of the following occurs just before the cell enters the G2 stage of
the cell cycle? *
O The nuclear membrane disintegrates.
O DNA replicates
O Centrioles form
O The nucleolus divides

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

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.

The trigonometry book says: sin^2(t) + cos^2(t) = 1 Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times: 1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle 2. Convert the angle from degrees to radians, say Rangle 3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and 4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle).
