Geographical variation refers to differences among populations in genetically based traits across the natural geographic range of a species. ... In the simplest case, we divide these factors into purely genetic versus environmental components to tease apart their relative contributions to observed phenotypic variation.
The first famous natural scientist to determine how plants change with altitude on tall mountains was Alexander Von Humboldt and Aime Bonpland when climbing some very high volcanoes in South America like Chimborazo at well ove 20,000 feet high and they observed that different plants grow at different altitudes as altitude increases so that as the mountain was ascended the new environments of temperature, moisture,etc would become abiotic for the lower plants but acceptable for the higher elevation plants. In these cases in South America, the lower elevations had very warm temperatures and high humidity so would grow tropical plants with probably large leaves like palm trees etc. On the other hand at high elevations the temperature would be significantly decreased and probably humidity decreased too so only rugged plants like say lichens could grow. At intermediate elevations, most likely say pine trees could grow as I know they do at moderate elevations in Honduras for example.
A. is your correct answer
Answer: if they help you break down food
Explanation:
Mutualism is a biological relationship between TWO or more organisms of different species (inter-specie) in which one or more benefits.
A good example is bacteria in the human intestine that helps to break down cellulose contained in food, thus benefitting humans.
The complete question is attached to the answer.
Answer:
The correct hypothesis would be - the food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire.
Explanation:
According to the image, we can find that the normal intestine fluid has the same pH as the pH of claire's Intestine fluid which is suitable for the breaking down of the food or protein in particular. It is also found that there is some amount of protein digested which suggests that there is no mutation in the active site.
According to the graph, claire is able to break down or digest the food completely if 1mg proteases enzyme is used so it proves the enzyme is produced less than normal. On the basis of this information, the correct hypothesis would be -
"The food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire."
