Since forces cause a change in motion or state of a body, friction is a force which opposes motion of an object over another.
What is frictional force?Frictional force or friction is the force that opposes the relative motion of one object over another at their surface of contact.
The two types of friction are:
static friction andkinetic frictionRough surfaces experience the greatest friction while smooty surfaces experience the least friction.
Hence, friction can be reduced by lubrication or polishing.
Based on the property of forces and friction:
Force is defined as a push or pull that starts, stops or changes the direction of a moving object.Friction is a force that opposes motion between two surfaces sticking or touching together.A sandy floor has the greatest frictional force among these surface.Friction is a force that opposes motion. It acts in the opposite direction of a moving object. Friction is a force that occurs when surfaces touch each other. Rolling friction is produced when an object rolls over a surface is produced.Rolling friction is produced when an object is rolled on a surface. Round objects like a Ball produces rolling friction.Riding a bicycle and using of wheelbarrow (kariton) are examples of rolling frictionA soccer ball rolling on the ground is an example of rolling friction.Sliding friction occurs between moving objects and a liquid or between an object moving in the air.Static Friction occurs when there is more force needed to travel an object in a surface than rolling Friction.A train going around its tracks is rolling frictionSliding friction opposes the sliding of objects over a surface.Mucus produced by snails, help them move along the ground because Mucus reduces friction.Therefore, it can be concluded that generally, friction opposes motion of an object over another.

Explanation:
Identify the independent variable in the experiment represented in Figure 3B. Justify the use of hair from individuals unaffected with FT as the control in the experiment represented in Figures 3A and 3B. Based on the data in Figure 3B, describe the FT effect of the disorder on the proportion of hairs in the growth phase. Based on Figure 2, if individuals 3 and 4 have another child, calculate the probability that the child will be affected
Based on the experimental data, the independent variable is the protein fibroblast growth factor-5, FGF5 which is unaffected by hair growth.
What is FT?Familial trichomegaly, FT, is a genetic disorder which results in abnormally long eyes in affected individuals.
FT is caused by a mutation in the genes that coded for the protein fibroblast growth factor-5, FGF5.
In research, the independent variable is unaffected by changes in another variable, butis changed and controlled by the researcher.
Based in the experiments, the independent variable is the protein fibroblast growth factor-5, FGF5.
Therefore, the independent variable is the protein fibroblast growth factor-5, FGF5 which is unaffected by hair growth.

2. could chromosome 3 be homologous with chromosome 1? Explain why.
3. could chromosome 4 be homologous with chromosome 1? Explain why.
4. could chromosome 5 be homologous with chromosome 1? Explain why.
Chromosome 1, 2 and 5 are homologous chromosomes whereas Chromosome 3 and 4 are different.
Which Chromosome is homologous to each other?Chromosome 2 is homologous with chromosome 1 because of the presence of similar gene on both sides. Chromosome 3 is not homologous with chromosome 1 because both chromosomes have one different gene.
Chromosome 4 is not homologous with chromosome 1 due to difference in the whole shape of both chromosomes from one another. Chromosome 5 is homologous with chromosome 1 due to the presence of same size and genes.

What is one possible result of a mutation within a start codon? A stop codon?
The result of a mutation within a start codon is the non-start of the protein translation, whereas a mutation in the stop codon will long the length of the protein.
What are transcription and translation?Transcription refers to the process by which a fragment of DNA is used as a template to create an RNA molecule, usually a messenger RNA.
Subsequently, this mRNA sequence can be used to create a protein by a process called translation.
The triplets of nucleotides (codons) in the mRNA are read by the ribosomes during translation, thereby a mutation in the start codon would produce a nonfunctional mRNA.
Moreover, a mutation in the stop codon will long the length of the resulting protein sequence.

During _____, the homologous chromosome pairs independently align themselves at the equator of the cell.
Answer:
Prophase I
Explanation:
During prophase I, homologous chromosomes pair up and exchange sections of DNA.
During prophase I, the homologous chromosome pairs independently align themselves at the equator of the cell.
What happens in prophase I?DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis. The paired chromosomes are called bivalents, and the formation of chiasmata caused by genetic recombination becomes apparent.
Moreover, during prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.
Therefore, during prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. Prophase is the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures.
