Answer:
a. You record the air temperature every day for a week.
Explanation:
Recording air temperature every day for a week can be classified as making an observation.
Observation is a part of the scientific method. It is a basically a way of collecting data.
- During observation, our senses can be used or instruments.
- Depending on the nature of the study, specialized instruments helps to bridge the limitations of our senses.
- A good scientist is a keen observer.
- Making a record of air temperature usually by using a thermometer is a way of carrying out observation.
When you record air temperature, you are making an observation.
The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.
DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.
DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.
DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.
The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.
Number 1 is B and number 2 is C.
Answer:
C: If crossed with another heterozygous plant, the majority of progeny will have the dominant flower color.
Explanation:
Assuming the gene is represented an allele A, purple colour can be AA or Aa while white colour will be aa.
If a heterozygous plant Aa is crossed with another heterozygous Aa, the genotype of the progeny will be AA, Aa, Aa and aa.
Since allele A is dominant over a, it thus means that the phenotype of the progeny will be 3 purple and 1 white flowered plant.
<em>Hence, the majority of the progeny will have the dominant (75%) flower colour.</em>
The correct option is C.
