<span>The correct answer to this question is the following:
The crust’s role in biogeochemical cycles allows it to provide the raw materials necessary for life on earth. The crust actually affects earth in a massive variety of ways, that are impossible for us to understand without the research undertaken by scientists to understand more about its' effects on life.</span>
The answer is C lmk if you have any questions
Answer:
False.
Explanation:
The plants growth, maintenance and metabolism are controlled by the plant hormones and plant secondary metabolites. Five important plant hormones are auxin, gibberelin, cytokinin, ethylene and abscisic acid.
The plant hormones regulates the developmental process like root-shoot initiation, germination, flowering and fruits development. Auxins regulates the root development, gibberellins helps in seed dormancy, ethylene helps in ripening of fruits, cytokinin helps in shoot formation and abscisic acid causes leaf senescence and ageing.
Thus, the given statement is false.
The five major attributes of populations that help ecologists predict population growth or decline are -
1. Population size- This describes the total population in the area. It helps to ascertain if there is any need for population protection or any need for breeding.
2. Population density- It determines that large organisms live in less populated density places whereas it is easy to find groups and mates in a high populated places.
3. Population distribution- A population may have a uniform, random, or clumped distribution pattern
4. Sex ratio- It depicts the number of males to number of females. This will determine if the population will increase or decrease in the near future.
5. Age structure- defines the relative numbers of organisms in each age group. This indicates whether population will grow or shrink overtime.
