Answer:
A. The rice genes didn't make the right type of vitamin A.
Explanation:
Regular white rice does not have the gene to produce beta carotene. The human body converts the beta carotene into vitamin A.
To increase the nutritional value of rice, the gene for beta carotene from daffodil flowers was inserted into the cells of endosperm of rice.
This allowed these cells of the genetically engineered rice varieties to produce beta carotene. Production of beta carotene imparted golden color to the rice grain and hence, the name.
Answer:
Explanation:
a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density.
<h2>Specialists and Generalists </h2>
Explanation:
Niche is the role played by an organism that how it lives in an environment
Specialists
- Species that have narrow niches are called specialists and this type of niche is called realized niche
- It is narrow because of the presence of ecological barriers and is the space where a species actually lives
Generalists
- Species that have broad niche are called generalists and this type of niche is called fundamental niche
- It is larger than the realized niche due to absence of ecological barriers
- It represents all the environmental conditions where a species is able to live or can live
I'm pretty sure:
a) pepsin optimal pH: 3 and lipase optimal pH:8
b) No, because the stomach needs to be acidic and have an acidic pH but lipase is considered alkaline because its optimal pH is between 8-14 meaning it's an alkaline.
Not sure if this is any help but I hope it helped a little bit! :)
