Answer:
B. Puerperium, or fourth trimester of pregnancy
Explanation:
- Puerperium or the fourth trimester of pregnancy is also known as the postpartum period.
- This period starts immediately after the mother gives birth to a child.
- During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
- It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
- This phase is divided int three periods -
1. Immediate puerperium, or the first 24 hours after parturition
2. Early puerperium, which extends until the first week postpartum;
3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.
- This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
Generally, these vacuoles acquire 80% of the cell space. Vacuole is an important organelle present in the cells of plants, animals, protists, fungi and bacteria. Apart from water, vacuoles also contains different kinds of organic/inorganic molecules, solid materials and enzymes.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
Answer:
Dandelions may appear <u>quicker after harsh conditions and reproduce at a faster rate.</u> However, both dandelions and shrubs are considered <u>fast-growing plant species</u> that can be categorized as <u>pioneer species.</u>
Explanation:
Secondary succession refers to the changes that take place in a disturbed habitat. Pioneer plant species are those that <u>colonize new habitats after harsh climate conditions and that tend to reproduce at a fast rate.</u>
According to researcher J.W. Darlling (2008), pioneer herbs and shrubs are species that tend to grow faster in comparison to other species, making them excellent pioneer species.
This occurs thanks to plants that are <u>wind-pollinated</u>, such as dandelions, have a higher chance to appear because, as it is a disturbed environment, there are no insects or other fauna present. In addition, shrubs are <u>persistent species that are able to reproduce fast with limited soil availability</u> but a bit <em>slower</em> in comparison to dandelions.
