Answer:
yes they increase the rate that the are working normally
Answer:
A. a developing nation
Explanation:
Age pyramids are the age structure diagrams that represent the number and proportion of people at each age in a population. The base of the age pyramids represents the population in pre-reproductive age which is from 0 to 10 years. The overall shape of an age pyramid indicates if the population is increasing, stationary, or shrinking.
The age structure diagram for a developing nation has a broad base that tapers quickly towards the top. This means that a larger percentage of the population is in the pre-reproductive age group and reproductive age group with a smaller percentage of the population in the post-reproductive age. These countries have a great chance of future population growth.
Fact, BRCA genes help with cell division in the breast and prostate regions. Therefore, if they are mutated, the cell division process wouldn't function normally and possibly end up in cancer since the BRCA genes tend to be tumor suppressors (cancer is a malignant tumor).
Answer:
A model in which oak has a positive transition rate to the invasive and the invasive has a positive transition to oak.
Explanation:
An invasive species is the one which is non-native to the given ecosystem. Its growth hampers balanced ecological parameters and disturbs food web as well as normal flora.The overall effect of invasive species is decreasing biodiversity in selected ecosystem. As the ecologist needs to understand effect of this invasive species, firstly it is important to understand the transition of oak tress to invasive form. The transition rate is one of the deciding factor to introduce diversity in ecosystem. Also if the invasive form has the ability to revert back to original oak tress it would restore the original ecosystem. Thus a model in which oak has a positive transition rate to invasive and the invasive has a position transition to oak can be selected for the analysis. In other models, the final trnasition to grass would introduce lot of biodiversity in selected ecosystem which would be of little importance to understand transition rate.
Answer:
Energy storage, cell structure, signalling.
Explanation:
The functions that lipids serves in the body is - storage of energy, cell structure and signalling. Lipid is an efficient source and storage of energy. It helps in absorption and transportation of fat soluble vitamins ( A, D, E ,K). lipids work as a building block of cellular membrane. Lipids also act as a chemical messanger
