Answer:
Based on the cladogram, which two species share the most recent common ancestor?
lizard and owl
Explanation:
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
Answer:
The correct answer is b. All round seeds
Explanation:
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
Answer: D. None of the above
Explanation:
Heredity can be defined as a biological process that involves the passing on of characters or traits from parents to their offsprings genetically. These traits can be physical for example, height, colour of eyes or mental for example, intelligence.
