Propane, a renewable resource, is used in some heating systems.
Answers
Answer:
B is true
i took the test
Oil is a renewable energy resource. It is processed to make jet fuel. Thus, the correct option is B.
What are renewable energy resources?Renewable energy is the energy which is derived from natural sources which are replenished at a higher rate than they are being consumed. Sunlight and wind are the two such sources of energy which are constantly being replenished from the planet. Renewable energy sources are present in plentiful amounts and are found all around us.
Jet fuels are the energy fuels which are typically made by the blending and refining of various crude oils such as petroleum distillation products including naphtha, gasoline, or kerosene in order to meet the specific military or commercial specifications required.
Therefore, the correct option is B.

Answers
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well.

As part of a forensic analysis, you have been asked to determine an individual's ancestry using skeletal indicators. The metric measurements you collect indicate that the individual is of European ancestry, but you see several nonmetric traits in the cranium that are typically found in individuals of Asian ancestry. Why might the two methods give different results
Answers
Answer:
Due to difference in the methods that is used for analysis.
Explanation:
The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

Binding of the lac repressor protein to the lac operator is regulated allosterically. This means that the presence of a specific small molecule that binds to the lac repressor controls whether the repressor can bind to the lac operator, and therefore whether the operon is turned on or off. Can you sort the following conditions based on whether they are associated with the lac operon being turned ON or turned OFF?
a. Allolactose is absent
b. Allolactose is present
c. RNA polymerase cannot transcribe the operan genes
d. The lac repressor protein cannot bind to the lac operator
Answers
Answer:
a. OFF
b. ON
c. OFF
d. ON
Explanation:
Allosteric regulation is a process by which a particular molecule activates or inhibits an enzyme, by binding to a site different from the active site of the enzyme. Allolactose is a disaccharide that binds to the allosteric site of the lac repressor protein, triggering a conformational change in the protein that prevents the binding of this repressor to DNA. Moreover, RNA polymerase (RNA pol) is an enzyme required for the process of transcription, and therefore when this enzyme cannot bind to operon genes the lac operon is being turned OFF. Finally, the lac operator is a nucleotide sequence where RNA pol binds, and the lac repressor binds to the lac operator in order to block the transcription of the lac operon.

Answers
Answer:

hopefully this helps.
Infections are one particular type of disease. An infection is a disease caused by a living organism (a germ), which is living in the body of the affected person. The germ may be a bacterium, virus, fungus or parasite.
Like all diseases, infections vary in how severe they and whether they need treatment. The common cold is a virus infection; colds are not dangerous unless a person is already sick or very weak. Tuberculosis is a bacterial infection, which can be very difficult to treat and causes many deaths every year.
All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.

a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.
Answers
Answer: b
Explanation:
Camels ears are lined with fur to keep out sand and other blowing matter
The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.
What camels are adaptations for heat and dehydration?Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.
Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.
Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.
