The lab setup shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail.

In this setup, which tubes contain at least one organism carrying on cellular respiration?
A) Tubes 1 and 2 only.
B) Tubes 2 and 4 only.
C) Tubes 3 and 4 only.
D) Tubes 2, 3, and 4 only.

Answers

Answer 1

Answer:

I would assume D

Explanation:

Tube 1 doesn't contain an organism so it can't be that one. Both a snail and a plant are considered an organism, and cellular respiration occurs in almost any organism's cells

Answer 2

Answer: D) tubes 2, 3, and 4, only

Explanation:

I got this question on a test and got it right:)

Erwin Chargaff is considered one of the pioneering scientists in the field of molecular biology. In one of his studies, Chargaff observed that a sample of human DNA contained approximately 30% adenine (A). Based on DNA structure, what are the expected percentages of the other nitrogenous bases in the sample?

Answers

10% thymine, 40% cytosine

20% thymine, 30% cytosine

30% thymine, 20% cytosine

40% thymine, 10% cytosine#

Answer:

30% thymine, 20% cytosine

Explanation:

In a typical DNA double helix pyrimidine; Cytosine and thymine always pair with Purine ;Adenine and Guanine. This pairing ensure that the double helix of DNA is maintained by the presence of Hydrogen between these organic bases.

For correct pairing all adenine must pair with thymine,and all Cytosine with guanine.Therefore for this to occur if 30 % of adenine is present,the composition and number of thymine(30%) must be available.If this percentage is not available the pairing will not occur.

Like wise 20% Cytosine must be present because ,then same amount of Guanine molecule 20% in the DNA molecule. must be present Thus Guanine percentage is 20%.

This give a total of 100(60+40)

This based on the Erwin Chargaff stoichiometric ratio of 1:1 .This states that the percentage of adenine =thymine,and that of Guanine=Cytosine,in the DNA of living cells should be equal. Thus; [A]+[G]=[C]+[T]=1:1

Describe the resulting cells of meiosis

Answers

Answer:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

100 POINTS!!!!!!!!!!! ( I NEED FAST ANSWERS ) Why do we use uranium for nuclear energy?

Answers

Answer:

Uranium is the fuel most widely used by nuclear plants for nuclear fission. ... Nuclear power plants use a certain kind of uranium, referred to as U-235, for fuel because its atoms are easily split apart. Although uranium is about 100 times more common than silver, U-235 is relatively rare.

Explanation:

i looked it up

Answer:

In a nuclear reactor the uranium fuel is assembled in such a way that a controlled fission chain reaction can be achieved. The heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.

A fish is swimming around the 720-meter perimeter of her pond. If she swims 10 laps in 120 minutes, what is her average speed in m/min?

Answers

Answer:

The average speed of the fish is:

60 m/min

Explanation:

You must take into account that the fish swims 10 laps, so you must multiply the perimeter by 10 to obtain the total meters swam:

720 m * 10 = 7200 meters.

Now, you just must divide the total meters swam by the number of minutes that the fish took to do this, so:

7200 m / 120 min = 60 m/min

Remember, ever you do an exercise like this, you must check the units, I mean, the units that the exercise wants to be the same you use, in this case, the average speed of the fish is 60 m/min.

Option B: Molecule 2

Explanation:

'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')

The number of each molecule is as follows:

Molecule 1 - Inside: 3, Outside: 5

Molecule 2 - Inside: 2, Outside: 3

Molecule 3 - Inside: 1, Outside: 5

Molecule 4 - Inside: 7, Outside: 4

Therefore the correct option is option b. 2

This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.
