Answer:
With the help of cellular respiration, the mitochondria produced energy-rich compound ATP (adenosine triphosphate).
The ATP molecule holds the energy in the form of its phosphate bonds.
This energy is released by hydrolysis of ATP which results in the formation of ADP (adenosine diphosphate).
Sometimes, the ADP is further hydrolyzed to produce more energy. It results in the production of AMP (adenosine monophosphate).
The energy released from ATP hydrolysis is in the form of heat which is coupled with all the cellular activities like cellular transportation, repair, replication, apoptosis et cetera.

b) A flowering plant possess sensitivity to external stimuli but a fire is not sensitive
c) A flowering plant is able to reproduce but a fire cannot reproduce
d) A flowering plant can respire but a fire do not respire
e) A flowering plant need nutrition to survive but a fire do not need nutrition to survive
f) A flowering plant grow in size and shape but a fire do not show any such growth.

Choose all the answers that apply.
In some plants, pink flowers are dominant over yellow flowers. If Marlo crosses two hybrids _____.
the ratio of pink to yellow flowers will be 3:1
50 percent of the offspring will be hybrids
none of the offspring will have yellow flowers
three-fourths of the offspring will have the same phenotype
half of the offspring will be homozygous for flower color
Answer:
A) option B, two homozygous recessive plants is correct
B) A, B, D and E is correct
Explanation:
A) Given purple flowers are dominant over white flowers
Let P represents allele for purple color of flower while p represents white color of flower.
In order to create all white offspring from a cross, the parents must have homozygous recessive genotype i.e pp
Hence, option B, two homozygous recessive plants is correct.
B) Given pink flowers are dominant over yellow flowers. Let “Y” represents allele for pink flower and “y” represent allele for yellow flower
If two hybrid parents with genotype “Yy” are crossed, then following offspring will b eproduced –
Yy * Yy
YY, Yy, Yy, yy
Out of four , two are hybrid offspring, three genotype i.e YY, Yy, Yy have the same genotype and both YY and yy are homozygous for flower color,
Hence, option A, B, D and E is correct.
