Get twenty people, from various genders and ages, to be your testees. Create a random test that has both analytical and logical problems, and get the 'testees' (I have no idea if this is a word or not) to do the test before and after spending time outdoors.
An independent variable is how much time they spend outside, and the dependent is how well they function afterwards. (I think).
The constant is what stays the same, so most likely the tests in this case (if taking my example)
I don't really know what you mean by control, though...
This is what I would've done if it was my homework assignment, I'd suggest looking over my answers to see if they're accurate or not. Hope I helped, and good luck.
What organism? If its plants, they give oxygen during the day and carbon dioxide in the night. While animals give carbon dioxide but take oxygen from the air. These carbon dioxide gas and oxygen gas go to the atmosphere and affect the carbon cycle and oxygen cycle.
Here is the cycle if you want to know more
Plants (give out oxygen) -> Animals (Use oxygen) + (given our carbon dioxide) -> plants (take oxygen)
and so on
1) Plant and animal cells are both categorized the same as prokaryotes or eukaryotes based on the presence of a particular membrane-bound organelle – the nucleus, bounded by the nuclear membrane.
Explanation:
Prokaryotic cells are distinctive by the lack of a definitive nuclear structure or nucleus. Eukaryotic cells have a definitive nucleus with a nucleolus and DNA strands and stores the genetic information or the genes which are encased inside the nuclear envelope or membrane. Prokaryotic cells have their DNA in their cytoplasm since they lack a nucleus.
2) The organelles/structures that are found only within plant cells are chloroplasts and central vacuole.
Chloroplasts are exclusively found only in plants. The chloroplasts contain the chlorophyll, the green pigment which helps the plants to absorb solar or light energy trapped from the sun to carry out photosynthesis.
The central vacuole, the largest organelle, membrane-enclosed sac filled with fluid called cell sap. The central vacuole provides basic support and structure, maintain cell pressure, store reserve food and waste materials, and contains enzymes which aid various cellular activities.
The answer is condensation and evaporation.
Answer:
Lack of ability to adapt to changes in the envrionment
Explanation:
Asexual reproduction produces offspring that are genetically identical to the parent and no DNA is mixed, so they would not be able to adapt because there would be no genetic variation.
