Answer:
All their descendants will be heterozygous for the skin color, Bb, expressing blue skin.
Explanation:
<u>Available data</u>:
- Smurfette has light blue skin
- Her family is a "true bred" or "purebred" line.
- She married a boy who has light yellow skin
- blue skin is the dominant trait expressed by the B allele
- yellow skin is a recessive trait, expressed by the b allele
Cross: Smurfette x Husband
Parentals) BB x bb
Gametes) B B b b
Phenotypes) blue skin yellow skin

F1) 100% of the progeny will be heterozygous for the skin color, Bb
100% of the progeny will be blue-skinned.
Note: Although the progeny is blue-skinned, they are not true-bred anymore.
Answer: a. penetration strategy
Explanation:
Penetration strategy is one of the marketing strategy to promote the business and enhance the sales. The goods and services are sold at low price initially to promote the production of more goods or merchandise at low cost and allowing the authority to obtain high profit percentage.

An object only becomes part of culture after meaning have been given to it. A rock in a field has no meaning until it is used as a tool or to build a fence.
Lysosomes are vital because they help break down different waste in your body like food
Slow reproduction process is a disadvantage of sexual reproduction. So option A is correct.
Sexual reproduction is much slower than asexual form of reproduction and the meiosis process is much longer and complex than mitosis. The process of sexual reproduction depends on the fertilization and zygote formation which are time consuming processes. This longer duration of reproduction process leads to lesser number of individuals in the population. In this case there may be instances of producing only one organism per year and if by chance no offspring is produced for certain number of years can lead to extinction of the species.
