It is true that r-related species have a short life span and an early reproduction cycle. R-related species also known as r-strategist have a short and simple life span. Due to their simple life span, their nutrient exchange rate with the environment is rapid. Unlike K-selected species, they have the ability to reproduce at a young age. They reproduce a large number of off-springs, but many of their off-springs tend to die before attainment of their reproductive age.
Answer:
texture
Explanation:
Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.
- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.
- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't
- Metals are malleable i.e. can be beaten into sheets.
Texture is not a property used to classify metals and metalloids.
Sexual means something physical and sexual reproduction is the creation of an offspring.
