Answer:
Genetic diversity is important because it could ensure that certain groups of individuals, species, or populations will be able to adapt to certain environmental factors. Thus, genetic variation helps the species in terms of its adaptability, survival, and its evolution
Explanation:
The difference is in their chemical structure. Simple carbohydrates have a simpler molecular form, and as such are super easy to digest and fairly quick form of energy. Sucrose and Fructose are examples of such simple carbohydrates
Complex Carbohydrates, form a larger chain, and come packed with fiber. They have more advanced components that offer better health benefits (fiber) and are digested for more energy. Additionally Complex carbs are used by organisms to store large amounts of backup energy. Examples of such things include Starch (plants) and Glycogen (animals and Humans).
Answer:
-
Periods of light-time
- Temperature
- Substrate/Soil type
Explanation:
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.
.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
