A feature of a pedigree that indicate that a certain trait is a dominant trait is that one of the parents always have to have the trait.
There are, however, autosomal dominance and X-linked dominance.
For an autosomal dominant trait:
- Appears equally frequent in both sexes.
- Both sexes transmit the trait.
- Present in all generations.
- When one parent has the trait and the other doesn't, approximately half of the offspring will present the trait.
For a X-linked dominant trait:
- Both male and females can present the trait, but more females usually present it.
- Sons with the trait always have a mother that presents the trait as well.
- Daughters with the trait always have either a mother or father that presents the trait, or both.
- Fathers with the trait always have daughters with the same trait.
B. 7
Nitrogen's atomic number is 7.
*an element's atomic number is both its number of protons and electrons*
*to find an element's amount of neutrons, subtract its atomic number from its atomic weight*
The given statement is false, as Paleolithic people thrived in the groups of 20 to 30 individuals.
At the time of Paleolithic, the hominins gathered together in brief societies, like bands, and survived by fishing and gathering plants, scavenging or hunting wild animals. The Paleolithic era is featured by the application of knapped stone tools, however, tools made up of woods and bones were also used by humans at that time.
Answer:
C) The Calvin cycle requires ATP and NADPH, which require sunlight to be produced
Explanation:
The light-dependent phase of photosynthesis includes the photolysis of water molecules. The released electrons are passed to PSII to PSI via electron carriers and finally to NADP+ to reduce it into NADPH.
Transfer of electrons via electron carriers also generates the proton concentration gradient which in turn drives ATP synthesis. ATP and NADPH formed during light reactions are used in the Calvin cycle as an energy source and electron donor respectively.
Hence, to continue, the Calvin cycle requires the synthesis of ATP and NADPH in the presence of light.
