A change in which no new substance is formed is called a physical change.

Examples: Crushing a can, Melting an ice cube, Boiling water, Breaking glass, Dissolving sugar in water, Shredding paper, and Chopping wood.

All of these examples may involve a change in shape, form, or appearance, but it DOES NOT involve a change in the molecule structure.

Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%

How do protons contribute towards making ATP?...
ivanzaharov [21]

Answer: Protons contribute towards making ATP by producing proton-motive force that provides energy for ATP synthesis.

Explanation: In the respiratory chain, the transfer of electrons from one complex to another is accompanied by pumping of protons out of the matrix. This creates a difference in proton concentration and separation of charge across the mitochondrial inner membrane. The electrochemical energy inherent in this difference in proton concentration called proton-motive force is used to drive ATP synthesis as protons flow back passively into the matrix through a proton pore.
