Rainforests are habitats for many plants and animals. However, habitat fragmentation is occurring because of human activity. When a rainforest is fragmented, a large area is divided into small patches that are isolated from each other. Species living in these patches are more likely to become extinct as a result of overcrowding and competition.

Which of the following is the best way to minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem?
A.
constructing boundaries and fences around each habitat patch
B.
building natural green pathways across the original habitat to join all the patches together
C.
building concrete roads across the original habitat to join all of the patches together
D.
introducing new species that compete with the existing species in each habitat patch

Answers

Building natural green pathways across the original habitat to join all the patches together. Option B

What is rain forest?

A rainforest is characterized by towering, largely evergreen trees and heavy rainfall. Some rainforests have existed in their current form for at least 70 million years, making them the oldest existing ecosystems on Earth.

Hence we can see that the best way to  minimize the effects of habitat fragmentation on the biodiversity of a rainforest ecosystem is building natural green pathways across the original habitat to join all the patches together.

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.

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.

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.

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.

Answers

Answer:

In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.

Explanation:

The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.

The correct options in the blanks are DNA, mRNA, Protein, mRNA, and DNA respectively.

What is gene expression?

It is the process by which cells produce protein from DNA molecules. DNA produces RNA which contains codes to produce amino acids.

Explanation:

This test is called Mixture Test and is performed quickly when there is no time to do more detailed and accurate tests.
