The xylem is the structure of the plant that is
responsible for transporting water from the ground up to the different parts of
the plant. It is composed water, inorganic ions, and a number of organic chemicals.
<span>
Xylem tissue is found throughout the plant
because not only does it transport water, but it also transports the nutrients
that the plant needs for different processes. Aside from being responsible for
the transportation of materials, the xylem is also used to replace water that
was lost during photosynthesis and transpiration. </span>
Sunlight, hope this helps :)
Stages of follicular development include in ovulation:
Primordial follicle
Primary follicle
Secondary follicle
Vesicular follicle
Ruptured follicle
Corpus luteum
Corpus albicans
The follicular phase (i.e., follicle formation) starts on day one of a typical 28-day cycle, which is marked by the beginning of menstruation, and lasts until today (i.e., ovulation). At this point, the antral follicle is FSH-dependent and starts to compete for the hormone with other growing follicles.
- Before an ovarian follicle releases its ovum, it goes through a number of unique phases. A limited number of primordial follicles emerge in the fetal ovary throughout the course of the first five months of development. The oocytes in these follicles are enclosed in a single layer of squamous follicular cells.
- There are only a certain number of primordial follicles that are stimulated to form at the beginning of each menstrual cycle. The early primary follicle, which has a core oocyte surrounded by a single layer of cuboidal-shaped follicular cells, is the earliest evident histological stage.
- When a follicular antrum is seen within the granulosa layer, secondary follicles can be distinguished from primary follicles. Hyaluronan and proteoglycan-rich fluid is found in the antrum.

Answer:
<em> A nick is created between G and A in GAATTC when using Eco R1 site while a nick is generated between G and G in GGATCC when Bam H1 is used. The difference in the nicks created is the main reason you observe two bands when you digest the circular plasmid with a mixture of both</em>
Explanation:
Circular plasmid containing : 9 kb of DNA
Eco R1 and Bam H1 are known as restriction sites in DNA ( i.e. special sequences found in a DNA ) hence they can be specifically cleaved by the restriction enzymes enabling the insertion of a gene. that is why you will get a same result when you digest the Plasmid with either Eco R1 or Bam H1
