The inability of a cell to take in or produce sugars prevents the synthesis of carbohydrates and nucleic acids.
Answer:
a. Anabolic pathways synthesize molecules, necessitate energy, and are endergonic.
Explanation:
Anabolic pathway refers to the metabolic processes that synthesize intricate molecules from simpler ones, generally through condensation (where monomers are linked covalently, generating water as a by-product). It demands energy for forming new bonds, which indicates that it is endergonic.
Conversely, the catabolic pathway pertains to metabolic reactions that dismantle complex moleculesinto simpler components, typically through hydrolysis (where water is utilized to sever bonds within the polymer). It liberates energy during the bond-breaking process, this indicates it is exergonic.
Based on this information we can ascertain that the correct answer is a. Anabolic pathways synthesize molecules, necessitate energy, and are endergonic.

During step 3, chromosomes switch genetic information.
Clarification:
Meiosis is a form of cell division occurring in gamete formation. This process consists of two main stages - meiosis I and meiosis II.
Within meiosis I, events such as crossing over and independent assortment occur, leading to the exchange of genetic traits between pairs of homologous chromosomes and the division of these chromosome pairs. Therefore, the two cells generated from meiosis I will be genetically distinct. Step 3 illustrates the crossing over that happens during prophase 1 of meiosis I. Consequently, this results in genetic variation among offspring.
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.
During photosynthesis, the surplus food generated by the plant is stored within the ground tissue.
