Answer:
Yellow smooth - 9
Yellow wrinkle - 3
Green smooth- 3
Green Wrinkle - 1
Explanation:
Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"
Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"
F1 cross -
true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)
F1 gamete will be RG, RG, rg, rg
F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.
Thus, R is dominant over r and g is dominant over G
F2 Generation –
RrGg x RrGg
Gametes will be RG, Rg, rG, rg
RG Rg rG rg
RG RRGG RRGg RrGG RrGg
Rg RRGg RRgg RrGg Rrgg
rG RrGG RrGg rrGG rrGg
rg RrGg Rrgg rrGg rrgg
R is dominant over r and g is dominant over G
Genotypes are –
RRGG - 1 (Smooth Green)
RRGg-2 (Smooth yellow)
RrGG-2 (Smooth Green)
RrGg-4 (Smooth yellow)
RRgg- 1 (smooth yellow)
Rrgg – 2 (Smooth yellow)
rrGG – 1 (wrinkled Green)
rrGg – 2 (Wrinkled yellow)
rrgg – 1 (wrinkled yellow)
Yellow smooth - 9
Yellow wrinkle - 3
Green smooth- 3
Green Wrinkle - 1
<u>Answer:</u>
<em>A constant is something whose value cannot be changed and is used for comparison purpose. </em>
<u>Explanation:</u>
The controlled variable is a type of variable whose value is kept constant during the experiment to get the desired or expected result. The difference between constant and a control variable is that the constant can never be changed.
However, the value of control variable can be changed but is kept constant with a purpose in an experiment to get the data. The controlled variable in a battery can be the multi meter that should be used for all the batteries.
Answer:
Photosynthesis uses carbon dioxide to make sugar and produces oxygen as a byproduct. Respiration uses oxygen to release energy from stored sugar and produces carbon dioxide as a byproduct. ... However, if the plants are growing, then over a period of 24 hours they will produce more oxygen than they consume.
Answer:
The correct answer is vertebral column and cranium
Explanation:
Vertebrates are the animals that are characterized by having backbone or vertebral column and apart from the vertebral column they also have a bony skull. Skull and vertebral column protect the brain and spinal cord in vertebrates.
Vertebrata is a subphylum under phylum Chordata and clade Craniata so vertebrates have both cranium and vertebral column. In vertebrates, notochord is present in the embryonic stage and is replaced by vertebral column in adults.
Animals that comes under the Vertebrata are fishes, mammals, reptiles, amphibians, and birds. So the correct answer is B and C.
