Potassium is actively transported into and out of the vacuoles in the guard cells.

There are different kind of potassium transport channels (KAT1, KAT2) that transport K+ inside and outside the vacuole of the guard cell, by the use of ATP (energy) and H+.

Potassium is actively transported into and out of the vacuoles in the guard cells. The sodium-potassium pump is responsible for the process of moving sodium and potassium ions across the cell membrane which is an active transport process involving the hydrolysis of ATP to provide necessary energy required. Accumulation of potassium ions in the guard cells causes turgidity which keeps the stomata open.

An astronomer states that Star P has a lower absolute brightness than Star Q. How would you translate this observation for a non

aleksandr82 [10.1K]

Answer:

Star P is smaller than star Q

Explanation:

Absolute brightness is defined as brightness of a celestial object or star from a Standard distance usually taken as 10 parsecs from Earth. If one star is brighther than the other then there can be two variable playing major role given that they are at same distance –

a) composition of star and

b) Its size.

The larger the star, the more energy it will emit per second and hence more will be its absolute brightness.

Thus, star P is smaller than star Q

The portion of the small intestine that attaches to the cecum is the? appendix. ileum. haustrum. jejunum. duodenum

Rus_ich [418]

The portion of the small intestine that attaches to the cecum is the Ileum.

Hence Option (b) is correct.

With a length of almost 1.8 m(6 feet), the ileum is the section of the small intestine that is the longest.

Compared to the jejunum, it is thicker, more vascular, and has more advanced mucosal folds.

At the ileocecal sphincter, the ileum connects with the cecum, the first segment of the large intestine (or valve).

The small intestine's coiled tube is separated into three sections. These are the duodenum, jejunum, and ileum, arranged proximally (at the stomach) to distally.

The 25.4 cm (10 in) long duodenum, which starts at the pyloric sphincter, is the shortest section.

The jejunum connects the duodenum to the ileum and is roughly 0.9 m (3 feet) long (in life). The jejunum and the ileum, the last section of the small intestine, do not have a distinct boundary.

Hence, The portion of the small intestine that attaches to the cecum is the Ileum.
