Answer: 1. do honeyguides in different areas of the world have a similar symbiosis with humans?
2. how old are the birds when they learn to respond to the humans' calls?
3. could other birds in the region form a similar symbiosis with humans?
Explanation:
Answer:
In C3 photosynthesis, the reactions that require ATP take place in
B) the Calvin cycle alone.
Explanation:
In C3 PLANTS PHOTOSYNTHESIS OCCUR IN TWO STEPS-
1. LIGHT stage , WHICH TAKES PLACE IN LIGHT. In this stage water is split and ATP is released.
2. DARK stage, which takes place in dark. This the stage where calvin cycle takes place which require ATP, i.e energy. In this process sugar is produced with help of carbon dioxide. In this carbon dioxide is accepted by 5- carbon molecule ribulose-1, 5-biphosphate, which result into two molecules of 3- phosphoglycerate. this three carbon compound. hence is called as C3 pathway. hence C3 plants.
Answer:
The phosphorus in all biological tissues can be traced back to phosphorus weathered from rock.
Answer:
Explanation:
Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.
Active transport requires cellular energy and are of two types:
primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Active transport helps in the uptake of glucose in the intestines.
Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.
Cotransport helps in the transport of glucose across the cell membrane.
