Question

some help me with these please!!!
--------------------------------
all 7 questions...

Answer 1

Ello !!

here is your answer !!!

1 ) a small intestine absorb the digested food through finger like a structure that is called " Villi "

" Villi " it is finger like projection that absorb the essential component from a small intestine for example a water, food proteins , vitamins

==============================

2) stomata :-

stomata is an closing and opening which help in process like transpiration and gaseous exchange .

here is daigram to show the opening and closing of stomata.

stomata help in process like transpiration .
as well as gaseous exchange.

transpiration is process of loss of water is known as transpiration.

stomata help in gaseous exchange like exchange of gas carbon dioxide and oxygen.

===============================

3 ) following are the process that show respiration in the presence of oxygen or in absence of oxygen.

1 ) aerobic respiration :-

the respiration that take place in presence of oxygen is known as aerobic respiration.

here in this case glucose converted into carbon dioxide water and energy

here is equation that show aerobic respiration.

Glucose + pyuravate ==> Co2 + H20 + 38 ATP ( energy )

mitochondria is a site of aerobic respiration.

=============================

anaerobic respiration :-

the respiration that take place in absence of oxygen is known as anaerobic respiration.

here in the case of yeast

Glucose + pyuravate ==> C2H5OH + CO2 + 2 ( ATP ).

in this process there is formation of ethanol. or alcohol.

in the case of human being following are the respiration that take place ( anerobic )

Glucose + pyuravate ==> lactic acid +. Co2 + 2 ATP (energy ) .

* I have don't remember the formula of lactic acid.

here in this case there is formation of lactic acid and this cause cramps in human being then there is insufficient supply of oxygen.

=================================

4 ) inhalation means:-

the process of breathing in is known as inhalation.

there is inhalation of oxygen by human beings.

inhalation does not take place in formation of energy.

2 ) exhalation:-
the process of breathing out is known as exhalation.

generally there is exheletion of carbon dioxide water molecule with energy.

================================

5 ) following are the list that occur during the process of photosynthesis.

1 ) absorption of Sunlight by photosynthesis pigment.

2 ) breakdown of water that is photolysis .

3 ) conversion of light energy into chemical energy.
that is get from the Sun.

4) there is reduction of carbon dioxide to carbohydrate.

===========================
6 ) the ascent of SAP or upward movement help in transportation of water to upward

there is creation of osmotic pressure or root pressure.

when the transpiration occurs from leaves there is osmotic pressure created so that there is pull of water from the root of plant to get water to upper part of plant.

===============================

7) as we know that through the heart blood flow toys so that is known as double circulation.

firstly oxygenated blood is a started from left auricle and then goes to left Atrium

after going to left Atrium it goes to the heart and true heart it is pumped out throughout the body and there is IT Gate deoxygenated

after getting deoxygenated it is carried out by viens .

from left atrium. it goes into right ventricle and then right Atrium ( deoxygenated ) .

as you know that human beings are mammals so it require continuous energy for maintaining the body temperature so there is requirement of double circulation.

hope it helps you dear !! !



thanks !!!
