Answer:
B. 3. Right-handed coil: 1.left-handed coil
Explanation:
Phenotype is what you see - the visible or observable expression of the results of genes, combined with the environmental influence on an organism's appearance or behavior.
When Nn is crossed with Nn, they will produce offspring with NN, Nn, Nn and nn genotype.
N - Dominant allele
n - recessive allele
The phenotypic ratio of this offspring is 3 right-handed coil and 1 left-handed coil.
A company that makes pain relief medication tests the effectiveness of their own medicine compared to that of three other brands.
Answer: Options B and E are accurate
Explanation:
The three clades deutorostomia, and protostomia are bilaterans. Ecdysozoa is under protostomia. Invertebrates includes organisms without a backlog making the difference from vertebrates. Insects are not part of the lophotrochozoans although they also shed their exoskeleton. All animals share a common ancestor with the sponges and placozoa diverging first from the more complex animals. Lophotrozoa including 5 phylas which are all invertebates including platyhelminthes, rotifera, mollusks, nermatea and annelida.
Fermentation occurs in anaerobic respiration, and produces less energy than in aerobic respiration due to the lack of ETC because oxygen is not present.
Answer:
The correct answer is allopatric speciation.
Explanation:
Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.
So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.
