Answer:
The correct answer is option c) "It is necessary to have a completely functioning pentose phosphate pathway for a tissue to synthesize ribose phosphates".
Explanation:
While the pentose phosphate pathway is the most common way at which a tissue synthesize ribose phosphate, it is false to affirm that it is necessary for ribose phosphate synthesis. Tissues have alternatives to the pentose phosphate pathway to synthesize ribose phosphate. For instance, the nucleotide salvage or the salvage pathway allows tissues to synthesize ribose phosphate from intermediates in the degradative pathway for nucleotides.
Options for the question have not been given. They are as follows:
A. a lack of urban health care capacity
B. cultural disregard for women and women's health
C. prudence's family medical history
D. a lack of previous medical problems
Answer:
C. prudence's family medical history
Explanation:
Sociological factors include the factors related to human society. These factors stem from the way a society functions and effects the people which are a part of it. The way the society is structured and developed, impacts the people.
Prudence died during childbirth. There can be many sociological causes of her death like low status of women or poor medical facilities in her society. However, her family medical history will not be considered a sociological factor. Family medical history also depends on other factors like genetic composition of the family which is not a sociological factor.
The walls of xylem cells are lignified (strengthened with a substance called lignin ). This allows the xylem to withstand pressure changes as water moves through the plant.
The cell membrane is flexible because of the presence of oil like substances called phospholipids, which gives it a fluid nature. While as the cell walls are rigid because of the presence of the thick layers of the substances like cellulose in plants, chitin in fungi and peptidoglycon in bacteria.
A variation is a reference to the differences or deviations, such as the structure and form, as for crossing over is the exchange of genetic material between the non-sister chromatids of the homologous chromosomes during meiosis.
