The equation AU = Q - W describes which one of the following?
O A. Second law of thermodynamics
O B. Efficiency of a heat engine
O C. Work done by a gas
O D. First law of thermodynamics
SUBMI

Answers

Answer 1

Answer:

D. First law of thermodynamics

Explanation:

The first law of thermodynamics refers that energy can be tranferred or changed form one form to another but it can neither be destroyed nor be created. hence, it is also known as law of conservation of energy.

The equation  ΔU = Q − W describes the first law of thermodynamics.

Where

U is the internl energy of the system.                                  ΔU is the change in U.                                                          Q refers to the total heat supplied into the system (include both addition and release of energy in the system).               W is the net work done by the system.

Hence, the correct option is D.

Answer 2

Answer:

Option D, First law of thermodynamics

Explanation:

The first law of thermodynamics states the following -

[tex]dU = Q-W[/tex]

where dU  represents the Heat added to the System

Q represents the Change in Internal Energy OR net heat transfer OR sum of all heat transferred into and out of the system

W represents the Work done on the system

The first law of thermodynamics is based on the application of the conservation of energy principle to heat and thermodynamic.  

hence, option D is correct

Answers

Answer:

Explanation:

Short hair (S) is dominant over long hair (s), and black coat color (B) is dominant over albino (b).

A female of a true breeding line with a black coat and long  hair is mated with a short haired albino male (also from a true breeding line)

parents genotype      BBss  x    SSbb

gametes                       Bs     x    Sb

F1 generation geenotype    BbSs

Phenotype- They are all with black coat and short hair

Mating of F1   BbSs  x  BbSs

   Percentage of offspring homozygous for both characters:

  Bb  x   Bb           Ss   x   Ss

 BB Bb Bb bb     SS  Ss Ss ss

 1/4             1/4         1/4       1/4

1/4*1/4 = 1/16 = 0.0625 = 6% for each homozygous characters (BBSS-6% and bbss-6%)

The genotypes of the homozygotes are BBSS and bbss

The phenotype of BBSS is black coat with long hair

The phenotype of bbss is an albino with short hair

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria

Answers

Answer:

A.The bacteria in the culture tube were already dead when you made the plate

Explanation:

Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.

Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.

There can be several interpretation for the absence of bacteria such as:

The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.

Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.

d. The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.

e. The cell expends energy to transport materials into the cytosol.

Answers

Answer:

The correct answer is:

The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.  (d.)

Explanation:

Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.

The various types of endocytosis has a common feature of:

1. invagination of plasma membrane forming pockets around the target particle.

2. the pocket pinches off from original plasma membrane

3. forming a new intracellular vesicle containing the target particle.

The different types of endocytosis includes

a. pinocytosis (cell drinking): takes in extracellular fluids

b. phagocytosis (cell eating): large solid particles are taken in by cells

c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.
