If the dominant allele is t and the recessive allele ("non-taster") is n, than tn and tt are the genotypes of a "taster". tn is heterozygous and tt is dominant homozygous. nn is the genotype of a "non-taster" and it is recessive homozygous.
Since the somatic cell count of a roundworm is four, the gamete count would be two. gamete count is half of somatic.
Answer:
Option B: Molecule 2
Explanation:
'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')
The number of each molecule is as follows:
Molecule 1 - Inside: 3, Outside: 5
Molecule 2 - Inside: 2, Outside: 3
Molecule 3 - Inside: 1, Outside: 5
Molecule 4 - Inside: 7, Outside: 4
Therefore the correct option is option b. 2
This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.
Hope this helped!
Well theory isnt proven. It means you have a strong idea about the subject your talking about. So if a scientist finds evidence that suggests something against the theory then it can be changed.
Light energy is absorbed by a chlorophyll molecule and the photon is passed along a pathway to other chlorophyll molecules. The energy culminates in a molecule of chlorophyll found in the reaction center.
