Two centrioles are found in mitosis
Answer:
The weakest part of a long developing and adolescent bone is called growth cartilage (epiphyseal plate)
Explanation:
Both children's bones and adults' bones are at risk of injury. However, in the case of bones in a child, they are subject to an injury known as a growth cartilage fracture or epiphyseal plate. These growth cartilages are areas that are in full development in the vicinity of long bones. Its function is to help establish the length and shape of the bone in the process of maturation. The growth of a long bone happens from the end next to the growth cartilage. In adulthood, these growth cartilages are strengthened forming the bone.
Answer:
a) All males will have dark wings, all females will have light wings. See attachment
b) Males - 50:50 dark:light, females, 100% dark wings
Explanation:
The ZW sex determination system is different from the XY sex determination system. Females are ZW, whereas males are ZZ (in contrast to XY system where females have two of the same chromosome [XX] and males have two different ones [XY]).
a) The potential genotypes of the F1 are shown in attachment. This shows that all males will have dark wings (Ll) (all heterozygous) and all females will have light wings (l) (all will inherit l allele from father)
b) The potential genotypes of the F2 are shown in attachment. This shows that 50% of the males will have light wings (Ll), and 50% will have dark wings (ll). All of the females will have dark wings (L).
An exchange reaction occurs between compounds that, when written as a molecular equation, appear to involve the exchange of parts between the two reactants. An exchange reaction will occur when ions in solution form insoluble products, weak electrolytes, or non electrolytes.
