The answer would be B) Nitrogen Trioxide
We have that there are 5 main tissue types in most vertebrates: epithelial, connective, nervous and muscle tissue. It is clear that muscle tissue helps the movement of various parts of the body and it is not dound in the skin. Also, interstitial tissue is the name with which we refer to extracellular fluids like blood plasma and thus this is wrong too (sweat is not a type of tissue). Nervous tissue is also deep under the skin. Connective tissue is the tissue that connects other types of tissues with the bones etc.; for example there is conenctive tissue in the brain. Finally, the correct answer is epithelial; they form the outermost layers of our cell structure and they serve to protect the rest of the tissue as well as provide us with sensations from the outside.
The correct answers to these questions are the following:
1) By analyzing enclosures with different colors on the ground that can either favour or hinder the success of the populations.
2) Independent variable: number of generations.
3) Null hypothesis: different colors have no effect on the fitness of the populations.
4) It is a consequence of directional selection. Directional selection is a type of natural selection where the frequency of a trait is modified to benefit a phenotype in response to a change in the environmental conditions.
Answer:
a gas used during photosynthesi
Explanation:
The chemical equation of photosynthesis is 6CO2 + 6H2O=C6H12O6 + 6O2
O there is oxygen and it is a gas. This is because during photosynthesis, carbondioxide react with water in the presence of light energy and chlorophyll to produce glucose and oxygen. The oxygen produced is a gas and it is use during respiration of animals.
