Channel protein is a membrane protein that spans the phospholipidbilayer (a strongly non-polar environment).
The nervous sysyem because i looked it up on the internet. search gal stones effect which body system then but a dash .You will find that it says nervous system.
Biogeography is the study of geographical distribution of fossils, various species (plants and animals) and ecosystems throughout geological time and space
Answer:
Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).
Explanation:
Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.
During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.
With respect to the law of conservation of energy, it is necessary to consider:
- In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
- Energy in an isolated system does not vary, unless it comes into contact with another system.
- The amount of energy that is absorbed and obtained is equivalent.
In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.
Regarding other options:
<em> 1. In photosynthesis, it is not </em><u><em>mechanical energy</em></u><em> that is transformed into chemical energy.</em>
<em> 3. </em><u><em>Oxygen is a product of photosynthesis</em></u><em>, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.</em>
<em> 4. It is true that the </em><u><em>sun gives off light energy that is absorbed by plants</em></u><em>, but it does not explain how this energy is transformed into chemical energy.</em>
Answer:
Independent variable: exercise
Dependent variable: grades
Constants: same kind of exercise, same set of students
Yes, there is a control group. The control group are the 10 people that do not exercise
Explanation:
In an experiment, the independent variable is that variable that the experimenter changes or manipulates. In this case, the independent variable is the EXERCISE.
The dependent variable is the variable that responds to changes made to the independent variable or the variable that the experimenter measures. In this case, the dependent variable is the GRADE of the people.
The constant is the variable that the experimenter must keep constant or unchanged throughout the experiment. In this experiment, the constants are the same kind of exercise, same set of people used.
In this experiment, there is a CONTROL GROUP. The control group is the group that does not receive the experimental treatment in the experiment. In this case, The control group are the 10 people that do not exercise
