describe the benefits and drawbacks of experiments in a laboratory compared with experiments in a natural setting
Answer:
Experimental set up in the lab.are under the control of the scientist,therefore they can manoeuvre the the surrounding conditions to suit the experimental set up for best results. In addition the lab.environment does not involve the complex interactions or reaction between the set up and the lab. environments, compare to the natural environment.
Natural experimental set up gives accurate results from the interaction of the organisms(e.g animals) under investigation in the natural environments,thus the results obtained are natural interaction of the organisms based on the environmental factors the organism are exposed to.However, the number of organisms are usually large,and therefore great effort is needed to determine the actual cause and effects of the factors affecting the organisms under investigations in this natural environments.

A. One of the late symptoms of MN is excessive edema, or build up of fluid within the interstitial space of tissue. Explain how loss of circulating blood protein (hypoalbuminemia) would cause edema with respect to hydrostatic and colloid osmotic pressure within capillary beds throughout the body.
Answer:
Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.
The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.
Explanation:
Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.
The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.
The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.
Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.

A forest fire destroys an area. A small population of trees and a large population of birds are both affected. Which type of
limiting factor causes this?
Odensity dependent
Odensity independent
O population dependent
population independent
Answer:
density independent
Explanation:
In Ecology, a limiting factor refers to an environmental condition that hinders the growth and distribution of organisms in an ECOSYSTEM. A limiting factor hinders or hampers the productivity of an organism in its habitat.
There are two major types of limiting factors that affect organisms in their ecosystem viz: density dependent and density independent limiting factors. Density independent factor limits the size of a population independently of how dense the ecosystem's population is. This means that density independent factor affects a population irrespective of its size. Example of density independent factor are natural disasters e.g earthquake, hurricane, forest fire as mentioned in the question.
In this question, both populations of trees and birds are affected irrespective of the size of the ecosystem's population.

The arrangement of the polar and nonpolar parts of phospholipids in the cell membrane has what type of an effect on the function of the cell membrane?
Group of answer choices
It helps to control what substances move in and out of the cell.
It makes the cell membrane more rigid.
It helps the cell to keep its shape.
It helps keep proteins out of the cell.
Answer:
It helps to control what substances move in and out of the cell.
Explanation:
Phospholipid bilayers are critical components of cell membranes. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. However, an important function of the cell membrane is to allow selective passage of certain substances into and out of cells. This is accomplished by the embedding of various protein molecules in and through the lipid bilayer. These proteins form channels through which certain specific ions and molecules are able to move. Many membrane proteins also contain attached carbohydrates on the outside of the lipid bilayer, allowing it to form hydrogen bonds with water.

Put the steps of transcription in order
The complementary RNA nucleotides are added.
RNA polymerase binds to the promoter.
DNA strands are unwound and separated
Answer:
1. RNA polymerase binds to the promoter.
2. DNA strands are unwound and separated
3. The complementary RNA nucleotides are added.
Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.
DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added. These are the steps of transcription in order.
What is transcription?Transcription is the process by which RNA molecules are synthesized from DNA templates. The first step in transcription is the unwinding and separation of the DNA double helix by an enzyme called RNA polymerase.
The enzyme binds to the DNA template strand separating the two strands and DNA template strand is further used for RNA synthesis, while the other strand is the non-template or coding strand. RNA polymerase then binds to the promoter region of the DNA template strand which is located at the start site of transcription.
After the binding, a complementary RNA starts synthesizing using the DNA template strand by adding complementary RNA nucleotides. As the RNA polymerase moves along the DNA template strand, RNA molecule starts growing which is complementary to the DNA template strand. This step is followed by elongation and termination of growing RNA molecule.
Therefore, transcription steps include DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added.
