When you do an experiment and come up with something that works, you are making inferences. Thus, the correct option for this question is D.
An experiment may be defined as a complete methodology that is carried out under a controlled environment in order to discover an unknown effect or law, test or establish a hypothesis, or illustrate a known law.
An inference may be defined as a conclusion that is remarkably based on observations. They are important in order to find the exact demonstration of the experiment on a specific topic to deduce a conclusion.
Without inference, one must treat what they hear or read in a very literal sense. But inferences make a more accurate and valid conclusion.
Therefore, when you do an experiment and come up with something that works, you are making inferences. Thus, the correct option for this question is D.

Answer: alleles
Explanation:
Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.

Any that you know would help!
A
commensalism
B
mutualism
C
parasitism
D
predation
Answer:
Option B. mutualism
Explanation: Mutualism is a symbiotic association in which both the organisms gets benefits from one another. Bees helps in the pollination by transferring pollen grains from one plant to another and in return the flowers provide food in the form of nectar to the bees and in this way both the organism gets benefited. So the relationship which is present between flower and bees
is Mutualism.
The type of DNA in each cell controls the rate of the cell cycle and the specific type of cells
formed
The size of the cell determines the number of cells that will be produced from each cycle.
Internal and external signals regulate the progression of the cell cycle at various critical
checkpoints
Hormones signal the start of the cell cycle, and DNA determines how the cell differentiates.
Answer:
The correct answer is internal and external signals regulate the progression of the cell cycle at various critical check points.
Explanation:
The cyclic event that helps to prepare the cell for division is termed as cell cycle.Cell cycle are regulated by various internal and external factors which regulates the passage of cell through various critical check point.
For example Maturation promoting factor helps in the progression of frog egg oocytes cells from G2 to M phase.
G1 cyclin CDK helps in the passage of cell from G1 to S phase.
