40 was D... right?

Yes!

 

[ijjukittu]

Then the answer is C, isn't it?

it was half-way between the lengths shown! so it was 100% b

 

[ijjukittu]

What about the DNA code guys???? A or B? :O

the one with the amino acids & bases given or that huge question asking which statement was NOT correct??

 

[SincerlyMe]

What did you answer for the question where we were supposed to calculate the volume of blood carrying oxygen in one minute?
I went for D which is 950

 

[TCHS]

I d

I got C which was 325

For the equilibrium question: The answer should be facilitated diffusion, osmosis, and diffusion. Because these occur due to random movement until equilibrium is reached. Active transport, on the other hand, doesnt cause an equilibrium to be reached.

Volume of oxygen to be calculated was 325 cubic cm.

Actual length of the cell Z was 50 micrometers.

The levels of protein structures that would be changed: primary, secondary, and tertiary. Because a change in the primary structure would in turn cause a change in the secondary structure, and that would cause the tertiary structure to be changed too.

Heart failure question: increased bp, fatty deposits in arteries and veins, reduced oxygen supply to cardiac muscle. (options 1, 2, and 3)

Equation of the NPP question: NPP=GPP-respiration.

Ecology question, which specie increases in number? Answer was C.

Increase in which factor increases chances of measles? Ans. was overcrowding.

For the DNA question: i wrote that more than one triplet can code for the same amino acid. This was the only thing shown by the figure.
It ddnt show that its being read in one direction.

C=O: in proteins and glucose. (straight chain glucose not ring structure)

Sucrose is made by condensation between fructose and alpha glucose, option B..

Size of prokaryotes: i wrote A. Not sure about this one though...

Bohr effect question: i chose the option that said decreases efficiency of attachment of oxygen, increases efficiency of release of oxygen.

Can anyone remember any other questions?

 

[babycry]

pressure in veins was b the 1 where skeletal muscles dont contract at rest

the 1 with a graph for pressure of heart the answer was b

the last 1 was d

the type of immunity for dead bacteria was artificial active immunity

the 1 for the plant in solution x and then y, the answer was a

the 1 for gene i chose the 1 where dna has 2 strands, cant remember exactly

 

[ijjukittu]

I d


I got C which was 325

I GOT 325 TOO

After which phase does cytoplasm begin to divide? I chose Anaphase while some of my friends went for Telophase

telophase

 

[ijjukittu]

it was telophase

 

[Jevin Sanoo]

telophase

It's telophase.

telophase..

 

[SincerlyMe]

Ohh, two incorrect answers for me till now !

 

[Alice123]

don worry... u'll do gud....

 

[SincerlyMe]

Another question was about the function that is NOT done by phospholipids in the cell membrane, I chose D

 

[TCHS]

I chose B which was the entry or something of water-soluble molecules, glucose & o2
:/

 

[L-Girl]

are u sure about that?

 

[TCHS]

I'm not sure about it! What did you choose?
