Answer:
a. all purple flowers in the F1 generation.
Explanation:
According to the given information, the allele for purple flower color (lets assume P) is dominant over while the allele of flower color (p). When two pure breeding purple (PP) and white flowered (pp) plants are crossed, the F1 would have all "purple flowered progeny with genotype Pp".
According to the Mendel's law of dominance, the hybrid genotype exhibits the dominant phenotype. Here, the allele "P" is dominant over allele "p". Hence, the genotype "Pp" would exhibit purple flower color and all the F1 progeny would have purple flowers.
All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.
H1
one proton
one electron
zero neutrons
H2
one proton
one electron
one neutron
H3
one proton
one electron
two neutron
D. HEARING is the sense most closely related to balance.
We maintain our balance through the detection of the movement of the fluid in our inner ear by hair cells.
Our inner ear has three semi-circular canals that are full of movable fluid and sensory hairs that are moved when the fluid moves. <span>These tell you which way your head and body is tilted in relation to gravity and give you information about movements and acceleration. Thy are also incidentally partially responsible for sea-sickness when the brain is fed conflicting information about the world from your ears and your eyes, the reason why you should get off your bed and go on deck to look at the horizon so the information matches.</span>
Answer:
The correct answer is option c) "drive-reduction theory".
Explanation:
The drive-reduction theory states that the motivation originates as a response to biological needs or a driver. This theory supports that motivation originates as an external desire to satisfy an emotional or physical deficiency. The statements of the drive-reduction theory are compatible with what the psychologist Dr. Williams believes about motivation. Dr. Williams believes that motivation is produced by an uncomfortable internal state, such as the drive-reduction theory, which states that motivation is produced as a desire to satisfy a deficiency.
