What is the difference between natural and artificial selection?

Difference b/w breathing & respiration ?

breathing is the process of intake and release of gases through the mouth, but respiration is the usage of food by cells to produce CO2 energy and water

Bravo! thanks!

ur welcome

What is the difference between natural and artificial selection?

natural is when 2 livivng organisms mate in their natural habitat, while artificial is the mixing of gametes in laboratories by humans

1) they will get deaminated(the amine group will be removed from the molecule, and the rest well be carbohydrate)
2) Deforestation, smoke from factories
3) less energy lost in walking and exercising
Welcome

oh ok got it

 

[snoonono]

oh ok got it

Good luck :]

 

[NIM]

1) amino acids are used in cells for bulding up proteins as the cells grow, and also for making enzymes. They are never stored, the excess amino acids are broken down by the process of Deaminiation
2) deforestation, co2 released by combustion, by respiration of animals. Less plants to absorb this CO2, thus increasing its concentration in atmosphere.
3) 1.less loss of sweat
2. i dont know

thnx dude...

"Name a salt with ALL the necessary ingredients for a fertilizer."

This isn't in the syllabus, is it? I mean, NPK are there but we have no salt with ALL of them. If any of you have the name, it'd be appreciated

Question: whats NPK???

 

[snoonono]

Question: whats NPK???

first the salt thing isnt in our syllabus, and NPK is a fertililser which has Nitrogen, Potassium, and Phosphorus

 

[NIM]

one more question!!!
Root hairs absorb ions, such as nitrate ions and magnesium ions, from the soil by active transport
Explain how ions are absorbed by active transport into root hairs...D

 

[GetSomeLife]

Question: whats NPK???

Nitrogen, Phosphorous and Potassium. The necessary elements for fertilizers

 

[NIM]

yea iam OMG where do u live ?!?!??!?!

rite now in INDONESIA....
and u

they are big in size so they need energy to pass the semi permeable membrane of the root hair cells

 

[snoonono]

rite now in INDONESIA....
and u

WOW!!!!!!!1 am in Abu dhabi, UAE, ASIA, which variant do u take?

 

[NIM]

WOW!!!!!!!1 am in Abu dhabi, UAE, ASIA, which variant do u take?
