Answer:
The function of DNA is tied to its structure. ... The sugars and phosphates link the nucleotides together to form each strand of DNA. When two strands of DNA come together, base pairs form between the nucleotides of each strand. Nitrogenous bases pair together in the following way: A-T and C-G.
The correct answer is C. Dilation, strong contractions, and delivery of the baby and the placenta
Explanation:
Labor and delivery is divided into three main stages: the first stage includes the latent phase in which cervical dilation begins (3 to 5 cm) along with mild contractions and the active phase in which strong contractions occur along with complete or almost complete dilation; the second phase is the fetus expulsion or delivery in which the cervix is fully dilated and the baby is born; and the third stage is the delivery or expulsion of the placenta that occurs as the placenta separates from the uterus and is expulsed through mild contractions. Thus, stages of labor and delivery are dilation, strong contractions, and delivery of the baby and the placenta.
Answer:
There are different structural adaptations that can help the organism survive in environment changes.
When the heat turns to cold a bear will hibernate. It's genetics allow the bear to keep itself warm (and of course the area that it hides itself in).
A bird will fly to a new area, where it's still hot.
Other animals, such as wolves will stop shedding and grow thicker and longer fur. This fur will help it stay warm in the winter.
All organisms have their system and each one is unique to the creature.
