Answers
Answer:
Contamination of the control sample (negative control) with DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories to amplify a target DNA fragment using primer pairs and DNA polymerase. In PCR experiments, it is imperative to include both positive and negative controls. The positive control refers to the amplification of a PCR product (amplicon) of known molecular size during PCR reaction in order to ensure the correct molecular weight of the target DNA fragment. The negative control refers to the inclusion of a sample without DNA in order to ensure that no contamination with DNA has occurred in the other samples.

What is the function of the Calvin cycle?
I’m not sure someone helppp!!! Quickly please
Answers
Answer:
its the the first option
Explanation:
This is because plants fix carbon dioxide from the atmosphere through photosynthesis. They produce sugar for food from the CO2.
Answer:It would be A i believe
Explanation: The enzyme RuBisCO is an organic compound that incorporates carbon dioxide. The organic molecule is reduced in stage 2. RuBP, the enzyme that begins the cycle, is regenerated in stage 3 so that it can begin the cycle. In short, fixing six carbon atoms from CO2 requires six turns of the Calvin cycle.
Natural selection is when
decides who survives and who doesn't?
Answers
Answer:
Nature
Explanation:
Natural selection is when nature decides who survives and who doesn't. Therefore, option A is correct.
What is natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others.
For instance, giraffes' long necks have allowed them to consume plants that other animals cannot.
Natural selection happens when people with a particular genotype have a higher chance of surviving, reproducing, and passing on their alleles to the following generation than individuals with a different genotype. Hence, option A is correct.

what happens to the carbon and oxygen from CO2 after it has been removed from the air by the plant via photosynthesis
Answers
Answer:
Plants absorb carbon dioxide from the air and use it to feed themselves in the process called photosynthesis. The carbon dioxide, through tiny pores called stomata, reaches the leaves of the plant. ... The factory emits Oxygen, or O2, into the ambient air until the process is finished.
Explanation:
After the removal of CO2 from air by the plant, then Carbon would be absorbed by plant, Oxygen will be emitted into the air.
Photosynthesis can be regarded as the process which involve the use of sunlight , carbon dioxide and water by plant, so that to oxygen can be created as we as energy in the form of sugar.After the absorption of the CO2 from atmosphere by plant through the stomata, the plant convert it into carbon and oxygen, and the oxygen will be released to the air.Therefore, the process is called Photosynthesis

Answers
Answer:
stabilizing selection
Explanation:
The illustration is an example of stabilizing selection.
Stabilizing selection is an evolutionary mechanism in which the extremes of traits are selected against, leading to an increase in the frequency of such traits in the population.
Laying too many eggs would lead to reduced fitness of the population of the bird as a result of malnutrition while laying too few eggs would lead to a reduction in the population. Reproduction needs to be optimized for maximum fitness.
There are different types of natural selection. One of them is stabilizing selection that favors the intermediate phenotype. The exposed scenario is an example of stabilizing selection.
Balancing selection, also called Stabilizing selection, decreases the frequency of individuals with extreme traits, and favors individual that exhibit medium-range characteristics, that gets to survive. Selective pressure is against h0m0zyg0tes, promoting genetic diversity. Genes expressing extreme characteristics in a h0m0zyg0sis are kept in a heter0zyg0us state, as a favorable adaptation to environmental conditions. In a graph, you will see that
→ The curve gets higher and thinner in the middle of the horizontal axe, indicating an increase in the heter0zyg0us genotype frequency.
→ The tails of the curve that coincides with h0m0zyg0us dominant and recessive genotypes frequencies will be near zero.
In the exposed example,
laying more than four eggs and less than four eggs are extreme phenotypes. laying four eggs is an intermediate favored phenotype.
The intermediate phenotype results in the species' fitness increase, so it is favored by natural selection.
Laying four eggs leads to well-nourished chicks, and all of them get to survive. Parents ensure their reproductive success.
