Mitosis unfolds through a sequence of stages marked by specific events in the cell.
a. True
b. False
Answers
Answer:
a. True
Explanation:
Mitosis is a cellular process where a cell divides into two identical daughter cells. Mitosis is divided into five sequential stages: prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into chromosomes, and mitotic spindle fibers start to form from tubulin subunits. Subsequently, during prometaphase, the nuclear membrane disintegrates and spindle fibers attach to the kinetochores of the chromosomes (centromeres). During metaphase, duplicated chromosomes line up along the cell's equator (i.e., the metaphase plate). Subsequently, during anaphase, the kinetochores move toward the cell's poles and sister chromatids separate. Finally, during telophase, kinetochore microtubules of the mitotic spindle disassemble, chromosomes arrive at the poles, the nuclei form at each pole and the chromosomes uncoil.

David comes into the emergency room late at night with a cut that will not stop bleeding. His mother, Rose, is worried that he has a bleeding disorder, just like his grandfather. The lab is closed, so the doctor cannot order a specialized coagulation test. However, the hospital does have a sample of blood from a classic hemophiliac. What is the simplest test the doctor could perform using David's blood to determine if it is missing factor VIII activity
Answers
Answer:
The doctor can mix a blood sample from the hemophiliac patient with David's blood.
Explanation:
This test is called Mixture Test and is performed quickly when there is no time to do more detailed and accurate tests. In the mixture text, two blood samples are mixed, where one is from a patient with hemophilia. when mixing the two samples, the doctor observes whether there were coagulation inhibitors in the patient's blood, and can then draw conclusions about the presence of hemophilia in the patient.

Imagine that you discover a new operon, called the hfc operon. This operon includes a series of structural genes: hfc A, hfc B, and hfc C. Each of these structural genes encodes an enzyme. These enzymes are involved in a metabolic pathway that results in the production of Molecule X. The gene hfc q, which is found outside of the operon, encodes Protein Q. When Molecule X binds to Protein Q, Protein Q binds to the operator of the hfc operon. When Protein Q binds to the operator, the structural genes of the operon are not transcribed. In the absence of Molecule X, Protein Q cannot bind to the operator, and the structural genes of the operon are transcribed.

Answer:
Harm to downstream fisheries, due to sedimentation of waterways from increased soil erosion.
Explanation:
Deforestation is the reduction of forest area in a given territory, both because of nature or man-made causes. It results in the loss of habitats for many animal and plant species, the destruction of natural peoples' habitats and livelihoods, and increases soil erosion and large floods in valleys. Often, a previously forested area becomes waste land.

A directional flow of electric charge
Answers
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart. Actually, electrons would go in the reverse direction across the cables.
What is electric current ?A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated.
The cell phone, trains, ships, refrigerator, and the motors in appliances like food processors all run on electricity. To be useful, electric energy must be converted into other forms of energy like heat, light, or mechanical.
Conventionally, a positive charge would go in the same direction as an electric current. As a result, the battery's positive terminal receives less current in the external circuit than its negative counterpart.

Case 2: In Ghana, cowpea is a legume plant that is a significant source of nutrition for people in this country. Attempts are being made to improve the yield and hardiness of this plant through a national crop improvement program. What has complicated this effort is the existence of several different collections of cowpea seeds. (Oppong-Konadu E, Akromah I, and Adu-Dapaah O. 2005. African Crop Science Journal 13:117-123) 1. How would you use protein analysis via SDS-polyacrylamide gel electrophoresis to sort through these collections so that duplicates could be eliminated and the remaining specimens could be sorted into subgroups that could then be further studied for properties of value in crop improvement
Answers
Answer:
It is expected that accessions/lines that exhibit the same bands in SDS-PAGE are phylogenetically similar (or even identical, duplicated, accessions) and therefore they can be removed when developing a core collection of germplasm. Subsequently, the accessions of the core collection can be clustered into subgroups (subpopulations) based on the distances observed between lines, reflected by different protein band patterns observed in SDS-PAGE. It is expected that these subpopulations adequately contain the genetic diversity of the core collection (useful in breeding programs).
Explanation:
SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is a technique widely used in molecular biology to separate proteins based on their molecular weights. In crop improvement programs, this information can result useful to identify accession lines and develop core collections. A core collection is a limited set of lines or accessions/varieties obtained from a large germplasm collection that is expected to contain the genetic diversity of crop species. In this case, cowpea lines that exhibit the same bands in SDS - PAGE are expected to be phylogenetically similar (or even identical/duplicated accessions), thereby these lines can be removed in order to conserve one accession in the core collection. Subsequently, the remaining lines can be classified by a phenogram based on distance measures clustered by UPGMA (unweighted pair group method with arithmetic mean). This cluster analysis enables the construction of a phylogenetic tree from a distance matrix based on protein patterns in SDS-PAGE, thereby obtaining subpopulations (clusters) which will be useful in breeding programs.

Which of the following best explains the evolutionary basis of human skin color? two parents who are heterozygous for each of the alleles have a greater probability of having a child with medium skin than one with very light or very dark skin in a diverse population, the distribution of the trait will be a bell curve, so most people will fall in the middle the inheritance of the alleles from each parent is completely random but in a population there may be natural selective pressure from the environment to favor different levels of expression multiple genes and multiple alleles each have an additive effect on how intensely the trait is expressed.
Answers
Answer:
From the given Options, Option C is correct.
the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression
Explanation:
The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.
The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option C.
