Explanation:
Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding will be presented. Finally, a description of artificial oxygen carriers will be presented. Most of these topics are covered in standard textbooks [6,10,54,113] and monographs on oxygen transport [112].
The flow of genetic information in molecular biology follows the following path, A) DNA is translated into protein B) DNA is transcribed into RNA which is translated into protein C) DNA is translated into RNA which is transcribed into protein D) RNA is transcribed into protein
Answer:
The Correct answer is DNA is transcribed into RNA which is translated into protein
Explanation:
The genetic information is unidirectional, from DNA to proteins. First, DNA is transcribed into an intermediary RNA molecule is known as transcription (TC), a further messenger RNA molecule (mRNA) is translated into a corresponding sequence of amino acids (translation). This concept of information flow is known as the central dogma of molecular biology.

In the following scenarios, identify the independent variable, and the dependent variable.
1. Endurance in high altitude mountain climbers with and without the use of supplemental O2.
a. Independent Variable:
b. Dependent Variable:
2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable:
b. Dependent Variable:
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable:
b. Dependent Variable:
Suggest a control group for each of the following experiments.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group:
5. Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group:
The independent variable produces an effect on the dependent variable, while the control variable produce no change on the results. In the exposed situations, the independent variables are supplemental O₂, low carbohydrate diets, hours spent studying biology. The dependent variables are Endurance of climbers, Weight loss, grades earned on exams. And the control variable might be time.
--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
1. Endurance in high altitude mountain climbers with and without the use of supplemental O2.
a. Independent Variable: supplemental O2
b. Dependent Variable: Endurance in mountain climbers
The endurance of climbers will depend on the use of supplemental O₂. If they use supplemental oxygen, they will have more resistance than if they do not use it. Supplemental Oxygen is influencing the climbers´ endurance.
2. Weight loss in subjects eating low carbohydrate diets.
a. Independent Variable: low carbohydrate diets
b. Dependent Variable: Weight loss
Having a low carbohydrate diet will lead the subjects to lose weight. Any change in the quantity of the carbohydrate will affect the individuals' weight.
3. The number of hours spent studying biology each week and grades earned on biology exams.
a. Independent Variable: hours spent studying biology
b. Dependent Variable: grades earned on exams
The more hours students spend studying, the higher grades they get on biology exams. The grades depend on the number of hours used to study and are proportional to this variable.
4. Cancer rates in students who smoke cigarettes are closely monitored over a 5-year period.
Control Group: Time → Five years
Time is constant in all the study groups. Independently of the number of cigarettes smoked, or the frequency in which subjects smoke, all the groups will be analyzed for 5 years, and this time-lapse is constant.
5.Weightlifters are given 400 mg of creatine phosphate every day for 90 days. At the end of the 90-day period each participant is evaluated for improvements in strength.
Control Group: Time → 90 days
Time is constant in all the study groups. Independently of the creatine phosphate mg provided to weightlifters, individuals will be analyzed for 90 days, and this time-lapse is constant.

Compare types of models. Which model of the human digestive system is most detailed?
A. Photograph of digestive system
B. Dissected pig
C. Artist drawing
D. 2D computer-generated model
The model of the Human digestive system that is most detailed is ( B ) : Dissected Pig
Pigs and Human have similar internal organs and the locations of each organ in both mammals are similar as well, therefore from the options the closest model that is most detailed as regards to the Human digestive system is a dissected pig.
A photograph of the digestive system does not provide a detailed model, also an artist drawing cannot provide as much detail as needed. A 2d computer-generated model will only present the digestive system in 2 dimensions hence it is not detailed enough as well.
Hence the most detailed model is a Dissected pig model.

What is the most common way sandstone is weathered?
Answer:
Hope desripction Helps! - Akito
Explanation:
Weathering and erosion are most rapid in areas of high relief, such as volcanic arcs, areas of continental rifting, and orogenic belts. Eroded sand is transported by rivers or by the wind from its source areas to depositional environments where tectonics has created accommodation space for sediments to accumulate.
Image result for What is the most common way sandstone is weathered?
Weathering and Transport of Sand
The grains of sand in a sandstone are usually particles of mineral, rock, or organic material that have been reduced to "sand" size by weathering and transported to their depositional site by the action of moving water, wind, or ice.

Gregor Mendel is regarded as the father of genetics due to his immense contributions to inheritance. Gregor Mendel worked with pea plants where he studied several traits in the plant. Mendel crossed two parents that are true breeding for a particular trait. The first filial generation (F1) were all dominant i.e. 0% recessive while the second filial generation (F2) were 3 dominant and 1 recessive i.e. 25% recessive.
