What are the application of lentiviral vectors

?


Viral vectors are tools commonly used by molecular biologists to deliver genetic material into cells. This process can be performed inside a living organism (in vivo) or in cell culture (in vitro).

How has photosynthesis developed in different types of plants?
Evgesh-ka [11]

Explanation:

Plants have been using light in this primal way for a large chunk of Earth's existence. But just how did they gain the ability to photosynthesize? The short answer is they stole it, about a billion and a half years ago, when single-celled organisms called protists engulfed photosynthesizing bacteria.

Assuming that both parents are heterozygous for the gene that causes the disease, what is the probability that the second child
LiRa [457]
The independent assortment of genes is a principle of Mendel and of genetics. Since humans are diploid organisms (they have 2 copies of their genetic information), we have that each gamete carries one of the two available alleles for each feature. These gametes are created in equal proportions.

We have that both parents are heterozygous for a feature, lets say H. Thus, their genotype is Hh. Hence, the child will get with probability 50%=1/2 H from the father and 50%=1/2 h from the father; same from the mother. By doing a Punnett square, we get that there is 1/4 chance that the child is HH, 1/2 chance that it is Hh and 1/4 that is hh. Since the disease is recessive (so both alleles are needed), we have that the chance that the kid has the disease is 1/4.

Why does external fertilization typically occur much more often in aquatic animals than in terrestrial animals? _____ Select one
mestny [16]

Answer:

The correct answer is option c. "The gametes must be kept wet to avoid desiccation".

Explanation:

External fertilization is an adaption were species reproduce sexually, but there is no direct contact between the female and the male species, because the egg is fertilized outside the female's body. This adaptation occurs more often in aquatic animals because the gametes must be kept wet to avoid desiccation and allow fertilization, which occurs much more easily on aquatic environments.

Fermentation is an anaerobic biochemical pathway with truly one simple intent.
larisa86 [58]

Answer:

We are losing Earth's greatest biological treasures just as we are beginning to appreciate their true value. Rainforests once covered 14% of the earth's land surface; now they cover a mere 6% and experts estimate that the last remaining rainforests could be consumed in less than 40 years.

One and one-half acres of rainforest are lost every second with tragic consequences for both developing and industrial countries.

Rainforests are being destroyed because the value of rainforest land is perceived as only the value of its timber by short-sighted governments, multi-national logging companies, and land owners.

Nearly half of the world's species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century due to rainforest deforestation.

Experts estimates that we are losing 137 plant, animal and insect species every single day due to rainforest deforestation. That equates to 50,000 species a year. As the rainforest species disappear, so do many possible cures for life-threatening diseases. Currently, 121 prescription drugs sold worldwide come from plant-derived sources. While 25% of Western pharmaceuticals are derived from rainforest ingredients, less that 1% of these tropical trees and plants have been tested by scientists.

Most rainforests are cleared by chainsaws, bulldozers and fires for its timber value and then are followed by farming and ranching operations, even by world giants like Mitsubishi Corporation, Georgia Pacific, Texaco and Unocal.

There were an estimated ten million Indians living in the Amazonian Rainforest five centuries ago. Today there are less than 200,000.

In Brazil alone, European colonists have destroyed more than 90 indigenous tribes since the 1900's. With them have gone centuries of accumulated knowledge of the medicinal value of rainforest species. As their homelands continue to be destroyed by deforestation, rainforest peoples are also disappearing.

Most medicine men and shamans remaining in the Rainforests today are 70 years old or more. Each time a rainforest medicine man dies, it is as if a library has burned down.

When a medicine man dies without passing his arts on to the next generation, the tribe and the world loses thousands of years of irreplaceable knowledge about medicinal plants.

Patent fingerprints, or visible fingerprints, are left on a smooth surface when blood, ink, or some other liquid comes in contac
lana [24]

Answer:

Answer is option A (True).

Explanation:

The fingerprint pattern of an individual is unique as no two individuals have the same pattern and it remains unchanged. So fingerprints are considered as one of the main types of physical evidence that can be recovered from a crime scene for identification purposes.

The three types of fingerprint impressions are;

Patent fingerprints or visible fingerprints - They are visible prints that are left on a smooth surface of another object when foreign substances such as blood, ink, or some other liquid present on the skin of a finger come in contact with the surface. These prints are easily identifiable and are visible with the naked eye without any technological enhancements.

Plastic prints - They are visible, three-dimensional prints that are left on soft surfaces such as freshly painted surfaces or materials like wax, gum, clay, soap, etc when a finger comes in contact with that surface resulting in an indentation. These prints are easily observable and no enhancement is required.

Latent prints - They are invisible fingerprint impressions that are left on a surface as a result of the perspiration, moisture or oil found in the ridges of fingers. Since they are not visible to the naked eye, enhancement is required upon their collection.
