Question 1 (True/False Worth 1 points)
(01.02 LC)
Sustainable practices refer to the practices, services, and guidelines we develop to protect ourselves within our environment.
True
False
Answer: True
Explanation:
Sustainable practices refer to the practices, services, and guidelines that are developed in order to protect ourselves within our environment.
Sustainable practices support human, ecological, economic and human health. With sustainability, it's agreed that there are finite resources and they should be used conservatively and maintained for future generations.
The statement is true.
Answer:
False; I did the quiz and I answered "True" and got it incorrect
If new genetic variation in the experimental populations arose solely by spontaneous mutations, then the most effective process for subsequently increasing the prevalence of the beneficial mutations in the population over the course of generations is
Answer:
binary fission
Explanation:
Binary fission is the main type of reproduction of prokaryotic organisms. In binary fission, the prokaryotic cell first duplicates its DNA and then divides into two cells, each one receiving one complete DNA molecule. Since binary fission is a type of asexual reproduction, this process increases the prevalence of beneficial mutations in a bacterial population. Moreover, transduction refers to the process by which a virus transfers genetic information from one bacterium to another bacterium. Conjugation is also a sexual mode of transfer of DNA from a donor (F+) to a recipient (F−) bacterial cell by direct cell-to-cell contact. Finally, transformation refers to the transfer of genetic material by which bacteria take up exogenous DNA from the environment and integrate it in their genomes.
In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:
Answer:
Nothing
Explanation:
A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.

•Differentiate between virus and viroids.
Viruses (Virus particles or virions) are usually units consisting of nucleic acids and coat proteins called capsids.
Viroids consist only of RNA, i.e. they contain no protein at all. Except for a few cases, viruses are not surrounded by a membrane.

Why is avian influenza (H5 N1) rarely transmitted from poultry to humans? Why is it is often lethal
in humans? Why is it rarely spread from person to person?
Answer:
Lacks the right key to unlock many cells.
Explanation:
Avian influenza (H5 N1) rarely transmitted from poultry to humans because it lacks the right key to unlock many cells in the upper respiratory tract so due to this action the virus is rarely transmitted to humans. Sometimes it is lethal to humans due to absence of antibodies for this type of virus. It is rarely spread from person to person due to inability to enters the other human body.

6. The first tree used to divide the dinosaur into two separate groups are the structure of their hips. What are the two groups and what do the group names mean?
The two groups are Tyrannosaurus Ornithomimus and Tyrannosaurus Coelophysis which are different from one another in shape and body structure.
The word Ornithomimus means ''bird mimic,” because it resembles the bird i.e. they are toothless and had beaklike jaws while on the other hand, Coelophysis means 'hollow form' and the specie has hollow limb bones that makes Coelophysis is a lightly body dinosaur that make it a fast hunter.

For example, when people began chopping down trees and making settlements in South America, fire ants started to move north in search for new homes. Eventually, they've became a huge problem to North America due to North America having no natural predators capable of eating these violent ants.
Answer:
Por ejemplo, cuando la gente comenzó a talar árboles y hacer asentamientos en América del Sur, las hormigas rojas comenzaron a moverse hacia el norte en busca de nuevos hogares. Con el tiempo, se han convertido en un gran problema para América del Norte debido a que América del Norte no tiene depredadores naturales capaces de comerse estas violentas hormigas.

You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)
Answer:
Nuclear lamins will no longer disassemble during mitosis
Explanation:
The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.
On your first research mission you make an amazing discovery by finding a new species living in the hostile environment of the Sahara desert. After observing it carefully you determine that it is not an autotroph, it is multicellular, and it does not contain any chitin. What is the best classification for it
Answer:
Animalia
Explanation:
A multicellular organism is an organism composed of two or more cells. Multicellular organisms include animals (i.e., organisms from kingdom Animalia), plants, and most fungi. Moreover, an autotroph is a living organism that can produce its own food by using materials from inorganic sources (e.g., water, carbon dioxide, etc); whereas a heterotroph is an organism that cannot produce its own food and thereby needs to eat other organisms, like plants or animals, to survive. Multicellular autotrophs are typically plants; whereas multicellular heterotrophs include all animals, fungi and some parasitic plants. Finally, chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is found in the cell wall of fungi, as well as in the exoskeleton of some animal groups such as, for example, insects, crustaceans, etc.

Individuals with a mutation in the gene for apolipoprotein B-100 produce very low levels of this protein, which is a component of LDL. How would accumulation of fat in the liver be affected and would this result in hypercholesterolemia or hypercholesterolemia
Answer:
Fats would accumulate in the liver and the individual would show hypocholesterolemia
Explanation:
Familial hypercholesterolemia is a genetic disorder caused by a reduction and/or defect in the low-density lipoprotein (LDL) receptor. Moreover, apolipoprotein B is the unique protein component of LDL, which plays a critical role in lipid metabolism by binding the LDL receptor. Familial defective apolipoprotein B-100 refers to an inherited disorder associated with mutations of the apolipoprotein B-100 that leads to moderate or severe cases of hypercholesterolemia. Mutations in apolipoprotein B-100 are associated with a reduction in the binding capacity of LDL to the LDL receptor, thereby leading to hypercholesterolemia.
