A closer cross-section view of a stem revealed continuous rings along the interior of the stem. Which type of stem could it be?

Answers

A stem with continuous rings along the interior is likely to be a woody dicot stem. Each xylem, the number of which increases by one a year, creates a ring. This is, for example, how trees are dated, by counting the number of rings in their trunks.

The answer is B.) Woody dicot

The statement which is not true about observation is as follows:

  • Observations are foolproof and should always be trusted or believed.

Thus, the correct option is A.  

What is Observation?

Observation may be defined as the process of analyzing or monitoring some activities that are performed either by you or others to interpret the outcome.

Some of the observations are not always true, and hence they can not be trusted or believed immediately.

Such observation required the action of modification and then can be observed cautiously with full concentration in order to eliminate some mistakes.

Therefore, the correct option for this question is A.

Explanation:

The function f(x) = 1.50x + 12.50 relates how much Kelsey pays for digital service, f(x), to the number of movies, x, she streams in a month. What is the value and meaning of f(18)?A. $27.00; this is the amount Kelsey pays for 18 months of service

B. $27.00; this is the amount Kelsey pays for 18 movies in 1 month

C. $39.50; this is the amount Kelsey pays for 18 months of service

D. $39.50; this is the amount Kelsey pays for 18 movies in 1 month

Answers

f ( 18 ) = 1,50 * 18 + 12.50 = 27.00 + 12.50 = $39.50,
x - number of movies.
Answer: D ) $39.50; this is the amount Kelsey pays for 18 movies in 1 month

Proximal tubule: The simple cuboidal cells of the proximal tubule are called _______ cells

Answers

Answer:

brush border cells....!!

Final answer:

The simple cuboidal cells of the proximal tubule are referred to as Proximal Convoluted Tubule (PCT) cells.

Explanation:

They have a distinct feature of having prominent microvilli on their luminal surface that forms a brush border.

These microvilli contribute to creating a large surface area which facilitates the maximization of the absorption and secretion of solutes including Na+, Cl¯, glucose, among others - a key function of this portion of the nephron.

These cells are responsible for the active transport of ions across their membranes and hence they possess a high concentration of mitochondria to produce sufficient ATP.

The PCT cells, forming a simple cuboidal epithelium, are active in secretion and absorption of molecules.

They are observed in the lining of the kidney tubules and are critical to the kidney's filtration function.

How does an increase in the annual melt season in Antarctica have a global effect? a. It causes an increase in heat related illness and death. b. It causes the global concentration of carbon dioxide to decrease. c. The water in the melting glaciers can cause sea levels to rise. d. None of the above is true.

Answers

The correct answer is option "C"

The water in the melting glaciers can cause sea levels to rise.

The increase in annual melt season indicates a prolonged melting (hot)  season which is primarily due to the impact of global warming. Global warming is increasing the highest temperature mark in the hot seasons on the planet which is adversely affecting the polar regions of earth. The ice in these Polar Regions has started melting. This ice when converted into liquid form flows through regions to reach sea and oceans and thus causes the rising of sea level

 c. The water in the melting glaciers can cause sea levels to rise.
