Answer:
The Nucleus
Explanation:
The nucleus is the most important part of a cell. It is the “information” headquarters and is in charge of the cellular activities. It contains the information that will tell the cell what to do, what to make, and when to divide. A nucleus is a small and very powerful part of a cell.
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:
C) phenotypic plasticity
Explanation:
- The ability of an organism to change phenotypically according to environmental conditions is known as <u>Phenotypic plasticity</u>.
Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.
Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.
- Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are <u><em>metabolically versatile</em></u><u><em>. </em></u>They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.
These bacteria are <u>notoriously adaptable</u> and <u>might be found in many different environments</u> (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.
<em>They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine</em>.
A soil can be low in ammonium and potassium ions because of increased acidity of the soil. The acidity is caused by hidrogen (H) and Al (alluminuim) ions. There few causes: acid rain, nitrate leaching, rainfall, decompositions of organic matter (leaves, corps etc) due to microorganism activity.
