R

Would someone clarify what the answer to the new organism question was? I wrote Bacteria and Virus but some of my friends said that the question said the organism was made up of cells, meaning it could not be a bacterium.

Ur ans is ryt . Dont worry

how can insulin secretion be varied but concentration in blood be constant..? seriously...that is common sense. I have checked on wikiepdia as well, insulin concentration and secretion rate are both varied

i wrote vaied and varied cox when insuline is secreated it depends on concentration of glucose and in blood it is less or more too

 

[Talha Irfan]

are you guys serious? Oestrogen and progestrone were clearly shown.......it was FSH (A)

Look at this graph bro, remember the graph, all three curves were similar except oestrogen, the red one is estradiol, a type of oestrogen

i seriously didnt knew the fuctions except LH and oestrogen ko select kiya tuka correct

 

[anamta]

Cuticle: impervious non cellular layer that prevents water loss. Insulin: secretion varies, amount in blood constant. Excretionco2: only muscles and diffusion. Hormone: oestrogen. 5: B. 6: can be bacteria, can't be virus

no it can't be becteria, they asked for a group of cells but becteria is unicellular organism so i guess it was C( it can be fungus and it can't be a becteria)

 

[Talha Irfan]

38) purple yellow CO2 concentration
39) Lungs - A one before volume starts increasing
40) how body loses heat? skeletal activity no, others two sweat and vasodilataion yes

 

[Talha Irfan]

no it can't be becteria, they asked for a group of cells but becteria is unicellular organism so i guess it was C( it can be fungus and it can't be a becteria)

Bacteria is a prokaryotic cellular organism consisting of dna, only virus does not consist of cells (so it could not be virus)

read this out becteria is a unicellular organism

 

[altox876]

What did you do in the question of air temperature is greater than body temperature?

 

[Talha Irfan]

https://en.wikipedia.org/wiki/Unicellular_organism
read this out becteria is a unicellular organism

ikr, so uni-cellular means what ? made of single cell, it said they (plural) are made of cells (plural)

 

[Talha Irfan]

What did you do in the question of air temperature is greater than body temperature?

cross tick tick

 

[altox876]

cross tick tick

I think I am the only one who did cross tick cross

 

[Talha Irfan]

I think I am the only one who did cross tick cross

:'( that was too easy

 

[anamta]

ikr, so uni-cellular means what ? made of single cell, it said they (plural) are made of cells (plural)

yupp! so it wasnt a becteria right ?? and what was the other choice? was it virus?

 

[altox876]

:'( that was too easy

I got confused by the wording of the question. It said the air temperature was higher so I thought that there would be no heat transfer through skin.

 

[Talha Irfan]

yupp! so it wasnt a becteria right ?? and what was the other choice? was it virus?

that's what i am saying it could be bacteria, it could not be virus

:O k don't worry, u got others right
