Answer:
false
Explanation:
not everyone has radial symmetry
The biological basis for assigning all human beings into a singe species is that there so many, even tons of living organisms living on earth. These organisms differ in their external and internal organs and so to differentiate them from them, they are being classified into kingdoms then classes then phylums then family.
Answer:
Statement B is false.
Explanation:
PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.
At the level of polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.
Thus, the correct answer is - option B.
Answer:
A - Stigma
B - Anther
C - Filament
D - Style
E - Ovary
F - Petal
Explanation:
The above are the correct answers of the image drawn in the attachment.
These are parts of a flower.
A - Stigma: It is the head of the pistil. It contains a sticky substance that catches pollen grains from other pollinators.
B - Anther: This is the head of the stamen. It produces pollen grain.
C - Filament: It is a long slender part of the flower. It attaches the anther to the flower.
D - Style: It actually holds the stigma.
E - Ovary: It holds the ovule. Found at the base of the pistil.
F - Petal: It attracts pollinators to the flower.
