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.

(1) Response to stimuli: Does the entity sense and respond to environmental change?
They just can reproduce when they are in the host
Answer:
Organisms need to detect and respond to changes in their internal and external environment. This is because the conditions inside our body must be carefully controlled for it to function effectively and survive. The control systems that allow organisms to respond to changes are incredibly important.
All control systems include:
Cells called receptors, which detect stimuli (changes in the environment).
The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.
Effectors which bring about responses, and restore optimum levels, such as core body temperature and blood glucose levels. Effectors include muscles and glands, and so responses can include muscle contractions or hormone release

Which phrase describes air pressure?
decreases with denser air
decreases as altitude decreases
equals mass divided by volume
decreases as a result of fewer air particles pushing down
The phrase which best describes air pressure is: decreases as a result of fewer air particles pushing down.
What is pressure?Pressure can be defined as a measure of the force exerted per unit area of an object or physical body. Thus, it is usually measured in Newton per meter square and calculated by using this formula:
[tex]P = \frac{F}{A}[/tex]
Where:
P is the pressure.F is the force.A is the area.The types of pressure.In Science, there are different types of pressure and these include the following:
Hydrostatic pressureOsmotic pressure Filtration pressureAtmospheric (air) pressureIn conclusion, air pressure is also referred to as atmospheric pressure and it generally decreases due to fewer air particles pushing down on the surface of planet Earth.

Observations are things that can be directly seen and talked about. Inferences are things that you believe correlate with each other. For instance, the dog wagging its tail must be happy because it is a guess, not a fact. An example of an observation is The girl is wearing a blue shirt with white straps because you can directly see it.
