Answer:
water and oxygen
Explanation:
The model in the image depicts photosynthesis and cellular respiration processes. Photosynthesis involves the synthesis of glucose and oxygen from carbon dioxide and water while cellular respiration involves the production of carbon dioxide and water from glucose and oxygen. This means that both reactions are opposite of one another.
According to the model, B is the product of cellular respiration in the mitochondrion used by photosynthesis while D is the product of photosynthesis in the chloroplast used by cellular respiration. B is likely water (H2O) while D is likely oxygen based on the provided options.
1. It is passed from the parents to the offspring.
2. Genes that determine each trait are located in chromosomes and are passed from parents to their offspring during reproduction.
3. genes
4. Height in a human being is determined by the sets of chromosomes found on genes obtained from each parent.
5. It creates new daughter cells to replace parent cells
15. 19 chromosomes
Answer:
gravity
Explanation:
Gravity is the cause of glacier motion; the ice slowly flows and changes in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster.
Answer:
incomplete dominance
Explanation:
incomplete dominance is when two different colored traits mix to create a color that is a mix
In step 2: Denaturation of the double-strand occurs.
In step 3: Annealing of the primer to the single strands.
In step 4: Extension or elongation takes place in this step.
Explanation:
In the PCR program an enzyme Taq Polymerase is used because it can withstand high temperature without altering its functions.
PCR is required for the amplification of DNA into multiple copies for experimental purpose. The artificial environment is created to form new DNA molecules from the sample in question.
The first step in replication is the opening of the double helix which is done by temperature treatment in PCR. The temperature would be 90 degrees for some 30 sec to two minutes.
The next step of primer annealing would be done at 52 degrees, this is the primer melting temperature.
The elongation of the DNA strand to be synthesized will take place at 72 degrees as Taq Polymerase can withstand that temperature.
Nearly one million copies of DNA will be made after 30 cycles of PCR.
PCR products can be stored at 4 degrees for some two months.
