MENDEL EXPERIMENT:
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. Therefore, in Mendel's experiments, the difference he discovered in the F1 and F2 generations is as follows: 0% of the F1 generation displayed the recessive phenotype, and 25% of the F2 generation displayed the recessive phenotype.Learn more at: https://brainly.com/question/290081?referrer=searchResults

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.

Qué factores interviene en la manifestación de los genes? (pregunta de indagación)
Toma en cuenta el concepto de gen: El gen es la unidad física básica de la herencia. Los genes se transmiten de los padres a la descendencia y contienen la información necesaria para precisar sus rasgos. Es la unidad molecular de la herencia genética, pues almacena la información genética y permite transmitirla a la descendencia.
Ahora, planteamos nuestra HIPÓTESIS o respuesta probable a nuestra pregunta de indagación. Recordemos que tiene que tener las dos variables en relación de causa – efecto.
VARIABLE INDEPENDIENTE (CAUSA) VARIABLE DEPENDIENTE (EFECTO) INTERVINIENTES
En este caso, la hipótesis podría ser: los genes se manifiestan de acuerdo a mecanismos genéticos y ambientales. En este caso, las variables independientes (causas) podrían estar representadas por interacciones génicas e intergénicas tales como relación de dominancia completa o epistasis (factores genéticos) o bien cambios de temperatura (factores ambientales), los cuales inciden sobre la variable dependiente (grado de expresión génica) y cuyos efectos están representado por el fenotipo del individuo.
La hipótesis es una explicación plausible a un fenómeno observado en el mundo natural, la cual puede ser comprobada (o rechazada) mediante el uso del método científico.La variable independiente o 'causa' puede ser definida como la variable que produce un efecto sobre la variable dependiente, y que no cambia a lo largo del experimento.Por otra parte, una variable dependiente es una variable que cambia a lo largo del experimento de acuerdo a la variable independiente y que el investigador mide para determinar el efecto de la variable independiente.Aprende más sobre este tema en:

When the enzyme is at its most active state and most of the substrate has bound the enzyme, an increase in the concentration of substrate will:____________
Answer:
An increase in the concentration of substrate will Increase enzyme activity.
Explanation:
Increase enzyme activity:
While the enzyme is toward its most active state and most of the substrate has bound the enzyme, an increase in the concentration of substrate will increase enzyme activity. Enzyme activity will progress until all enzymes' existing site is bound by substrates.In higher concentrations the enzyme molecules convert saturated with substrate, therefore there are some free enzyme molecules, so adding more substrate doesn't get many variations.Learn more about Enzyme, refer:

(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
