Answer: <span>A) Slow to repopulate
------
Genetic variation is an advantage of sexual reproduction. It increases survival and the ability to adapt in a species. Species with genetic variation can respond better to environment changes, since the genetic variability allows some to be immune to disease or adapt better to a change, and live to reproduce.
Slow to repopulate is a disadvantage because the species cannot recover quickly after a large disaster. It also means they cannot adapt as quickly to an environmental change.</span>

The blood vessels will thicken and make it difficult for blood to pass through because of the presence of white blood cells and plaque along the cell walls.</span>
Answer:
- An element is a pure substance that cannot be broken down into a simpler form.
- All elements are listed on the periodic table of elements.
- An element symbol begins with a capital letter; if there is a second or even third letter, it is a lowercase letter
Explanation:
An element is one of the two types of pure substances i.e. substances that cannot be broken down into simpler forms. Elements are made up of only one type of atom e.g. Fe, Cl2 (two chlorine atoms).
All known or discovered chemical elements are represented on the periodic table. In an order of increasing atomic number, elements are arranged from left to right on the periodic table.
The symbol of an element begins with a first letter written in capital letters while the subsequent letters can be written in lower cases. For example, Fe, Cu, Hg, Zn etc.
