The benefit of reduced gametophytes in seed plants is that they obtain nutrients from the sporophytes. Gametophytes are tiny and can develop from spores that are kept within the parental sporophyte's sporangia. This setup shields the growing gametophyte from environmental stress, allowing it to absorb nutrients from the sporophyte.
Answer:
The Trypanosoma most closely resembles green algae.
Explanation:
Trypanosoma exhibits structural similarities to green algae, which is unicellular. The primary similarity between Trypanosoma and green algae lies in their flagella, both utilizing them for movement from one location to another. Both are unicellular organisms where a single cell manages all life processes.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
Answer:
1. Habitat: Histosols are found in grasslands, swamps, and marshes, while aridosols are prevalent in arid environments like deserts.
2. Appearance: Due to their richness in organic matter, Histosols are darker, while the lower organic matter content in aridosols gives them a lighter hue.
3. Water retention: Histosols can retain water more effectively than aridosols.
4. Decomposition speed: Histosols also show a higher rate of decomposition compared to aridosols.
Answer:
The ovarian cycle manages the preparation of endocrine tissue, and the release of eggs within the female body.
The ovarian cycle consists of a follicular phase. Gradual increases of FSH and LH stimulatethe growth of follicles on the surface of the ovary. This progression ensures that the egg is ready for ovulation. As the follicles mature, they beginto emit estrogens and maintain low levels of progesterone. Progesterone secures the endometriumto help facilitate pregnancy. The ovum takes about seven days to journey through the Fallopian tube and implant in the uterus. At this stage, the cells number around 30-60 and are identified as the morula. If pregnancy does not occur, the lining will be shed. Estrogen levels rise after roughly five days, leading the menstrual cycle into the proliferative phase. The endometrium initiates regrowth to replace the weakened blood vessels and glands from the previous cycle.
