2. All light does share the same wavelength.
3. I would say mostly red and orange(two last one).
There is no keens cycle, but there is the Krebs cycle, which
uses, Glucose, ATP, and makes NADH, and FADH2 <span>
molecules after in the cycle.</span>
Answ
Left - antigen
Top Right - antibody
Bottom right - B cell
Explanation:
Antibodies (top right label) are Y shaped proteins involved in the detection of pathogens. They specifically detect molecules associated with pathogens called antigens (left).
Antibodies are produced by B cells (bottom right) which are a specialised class of immune cells that make up part of the adaptive immune system. B cells are often referred to as white blood cells.
This is an example of a food chain(C).
Note that density is equal to mass divided by volume.: d=m/v.
using this, we can find the answer to 5.a1.; 11.85/15=<u>0.79.g/ml</u>
<u>5.a2.</u> Ethyl alcohol.
5.b1: First subtract to the total mass by the mass of the beaker. 94-30=64g.
5.b2: Using the d=mv formula, 64/40=1.6g/ml
5.b3: The liquid is carbon tetra-chloride
5.c1: The volume is 67-50=17ml.
5.c2: d=m/v 192/17=11.3g So, the solid is lead.
5.c3: Did that :p
Hope this helps! :)
