Answer:
A balance between Osteoblasts and osteoclasts maintain bone tissue.

Answer:
A) tortoiseshell female; black male
Explanation:
Females have two X chromosomes and males have an X and a Y chromosome.
<u>The possible genotypes and phenotypes are</u>:
- XᵒXᵒ: black female
- XᵒY: black male
- XᴼXᴼ: orange female
- XᴼY: orange male
- XᵒXᴼ: tortoiseshell female
<u>Cross of a black female and an orange male</u>
<h3>XᵒXᵒ x XᴼY</h3>
The female only produces Xᵒ gametes. The male produces Xᴼ and Y.
The possible offspring therefore is: XᵒXᴼ (tortoiseshell females) and XᵒY (black males). The answer is A.
Nonmetals take electrons from the metals they are attracted to in order to become stable.
Answer:
Lack of diversity = higher chance of extinction
high levels of diversity = higher chance of survival
Explanation:
The probable reasons behind the extinction of some Caminalcules are:
The ratio of males and females were not equal so that there were natural fight between male Caminalcules to get a female. This was one of the cause for lowering the population leading to extinction.
The excessive short-life of these Caminalcules was one of the main reason for their extinction as it is more difficult to real organisms because there would be an inherent bias against observing these species in fossil aseemblegs.
5. The two vestigial structures of Caminalcules were ear muscles and tail bones.
