May I see the answer choices? If so, then I can help. :)
The first step in designing an experiment is the form a testable question.
D. Scientists use all of the above skills.
Answer:
estrogen
Explanation:
Birth control pills contain synthetic hormones which are naturally produced by females. These pills are used to prevent ovulation by maintaining a level hormone balance, so no egg is released. Combination pills contain estrogen and progestin, while progestin-only pills (also known as the minipill) don't contain estrogen. Progestins are synthetic hormones that act to mimic the naturally occurring hormone progesterone. Progestin-only pills are recommended in women who cannot take estrogen.
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters. For example, if one parent contributes a gene for blue eyes (c), and other parent contributes a gene for brown eyes(C), then we write the offspring’s eye color trait as Cc. This combination, of the two genes that determine the trait, is called a genotype. Hope this helped :)
