Answer:
R-factor.
Explanation:
Insulation can be defined as the process in which physical objects (materials) oppose the flow of current by providing a least resistance path or the opposition to the conduction of heat energy.
R-factor is an abbreviation for thermal resistance. The R-factor is the most commonly used measurement for providing all of the informations about the insulating properties of an insulator. Therefore, the measurement used for insulation is called the R-factor.
Most manufacturers specify the R-factor on the label of an insulating material.
Generally, the higher the R-factor of an insulating material the better it is for insulation.
Hence, the ability of a material to prevent the flow of heat or electricity (current) is largely dependent on its R-factor.

enzymes work by ___
a. changing the ph of the solution
b. transforming products
c. making bubbles
d. lowering the activation energy
Answer:
Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily. Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without.
In peas, axial flowers are dominant over terminal flowers. What phenotypic ratios would you expect in offspring from a cross between a known heterozygous axial-flowered plant and one whose flowers are terminal?
Answer:
Phenotype:
2/4 = 1/2 = 50% axial-flowered plant (Aa)2/4 = 1/2 = 50% terminal-flowered plant (aa)Phenotypic ratio 1:1
Half of the progeny will be axial-flowered plants (Aa) while the other half will be terminal-flowered plants (aa)

In flies, Red eyes are dominant to white. If a true-breeding red-eye fly bred with a true breeding white-eye fly, the offspring will be:
Answer and Explanation:
Available data:
Red eyes are dominant to whiteDominant allele RRecessive allele rCross: true-breeding red-eye fly bred with a true breeding white-eye fly
Parentals) RR x rr
Phenotypes) Red-eyed White-eyed
Gametes) R R r r
Punnett square) R R
r Rr Rr
r Rr Rr
F1) 4/4 = 100% of the progeny will be heterozygous for the trait expressing red eyes, Rr
---------------------------------------------------------------------------------------------------------
In Drosophila melanogaster, the fruit fly, the gene for the eye color is X-linked. So in this species:
- X⁺ expresses red eyes ----- > + is the dominant allele for red color
- X⁻ expresses white eyes ----> - is the recessive allele for white color
Option 1: true-breeding red-eyed females and white-eyed male
Parentals) X⁺ X⁺ x X⁻Y
Phenotypes) Red-eyed female White-eyed male
Gametes) X⁺ X⁺ X⁻ Y
Punnett square) X⁺ X⁺
X⁻ X⁺X⁻ X⁺X⁻
Y X⁺Y X⁺Y
F1) 4/4 = 100% of the progeny will express red eyes
50% of individuals are red-eyed males, X⁺Y
50% of individuals are red-eyed heterozygous females, X⁺X⁻
Option 2: true-breeding white-eyed females and red-eyed male
Parentals) X⁻ X⁻ x X⁺Y
Phenotypes) Red-eyed female White-eyed male
Gametes) X⁻ X⁻ X⁺ Y
Punnett square) X⁻ X⁻
X⁺ X⁺X⁻ X⁺X⁻
Y X⁻Y X⁻Y
F1) 2/4 = 50% of the progeny will be females expressing red eyes, X⁺X⁻
2/4 = 50% of the progeny will be white-eyed males, X⁻Y

Describe what happens during interphase. Be sure to include all three parts of interphase.
Answer:
Interphase is divided into three subphases which are G1 phase, S phase and G2 phase.
Explanation:
During G1 and G2 phases, the cell grows by producing proteins and cytoplasmic organelles. Cell growth and cell differentiation occur. In the S phase, synthesis of DNA occurs. The chromosomes are duplicated and DNA has replicated to form two identical sister chromatids joined together by centromere. During interphase, the chromosomes are not visible but appear as thread-like structures, chromatin. In general. Interphase is the phase where the cell prepares for cell division. It involves synthesis of protein and organelles, growth, replication of DNA, cell differentiation and energy storage.
A couple has three children, two without sickle cell anemia and one with sickle cell anemia. The mother has sickle cell anemia as well, while the father does not.
Make and defend a claim as to how this couple could have children with and without sickle cell anemia.
Answer:
Explanation:
The sickle cell allele is recessive. Hence, in order for any child of the couple to have sickle cell anemia, such a child will have to inherit an affected allele each from the two parents. This means that both the father and the mother must have affected alleles in their genotypes. In other words, two sickle cell alleles are required for the abnormality to manifest.
Let us assume that the sickle cell allele is represented by S and the normal allele is represented by A.
Now, it is established that the mother has sickle cell anemia, her genotype would be SS. The father does not have sickle cell, his genotype can either be AA or AS.
Assuming the genotype of the father is AA:
SS x AA
AS AS AS AS
All the children would be normal in this case.
Assuming that the genotype of the father is AS
SS x AS
AS SS AS SS
50% of the children would have sickle cell while the remaining 50% would be normal.
Therefore, in order to produce children with sickle cell, the father has to be AS, otherwise, he has to be AA.

How does temperature affect enzyme activity and why?
Answer:
The increase in temperature in a hot environment will cause the enzymes to denature (deform), the substrate will no longer be able to fit into the enzyme
However, in a cold environment the enzymes abd subtrate will be a lot more slower but they will still work.

In the given scenario, image B represent the relative directions of plate movement at this type of plate boundary. The correct option is B.
What is plate boundary?A plate boundary is a three-dimensional surface or zone where the velocity (speed or direction) of one lithospheric plate in relation to the next lithospheric plate changes significantly.
Divergent, convergent, and transformal plate borders are where the majority of seismic activity takes place. Sometimes the plates get hooked when they pass each other, creating pressure.
At the margin of the lithospheric plates, plate boundaries can be classified as convergent, divergent, or conservative.
Image B depicts the relative directions of plate movement at this particular type of plate boundary in the scenario.
Thus, the correct option is B.

Why is the cell cycle so tightly controlled in multicellular organisms?
Answer:
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.
All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences.
What is cell cycle?Cell cycle has been as the defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one has G1 phase in which the size of the cell increases, S phase synthesis of DNA takes place and the third step has G2 phase in which all cell ready to divide.
Cell has been defined as the base of the life as it has the structural as well as functional unit of life. Cell has been made up of pre existing cells and the cell contain various part cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

A. Insulin that can be used by humans
B. Human genes for enzymes that can be inserted into humans
C. The bacterial gene for insulin that can be inserted into humans
D. Enzymes necessary to treat human diseases
Organisms whose genetic material has been modified are called Genetically modified organisms. The bacteria can be used for the production of Insulin that can be used by humans.
What are GMOs and transgenes?Genetically modified organisms are altered and modified living things like animals, plants, a microorganisms that are modified by the methods of genetic engineering and recombinant DNA technology.
The genetic material that is modified and inserted in the host for the expression of the gene of interest is called a transgene. The genetically modified gene can be inserted in bacteria, plants and animals.
In the diagram gene for the production of human insulin is inserted in the bacterial DNA so the insulin produced can be used for the treatment of diabetic human patients.
