9. Which of the following is the example of the action of the autonomous nervous system? A. Kicking a ball B. Swinging of arms C
stellarik [79]

Movement of food in the small intestine. Thus, option "D" is correct.

<h3>What is the autonomous nervous system? </h3>

ANS is divided in two opposite systems: sympathetic and parasympathetic:

Parasympathetic nervous system: characterized by the tag "rest and digest" it decreases the heart rate, blood pressure, and breath. It increases the gastrointestinal motricity, letting the organism resting (this happen after a meal).

Sympathetic nervous system: characterized by the tag "fight or flight" it increases the heart rate, blood pressure, and breath. It decreases gastrointestinal motricity, letting the organism focus on its environment (this happen when we are in danger).

Thus, option "D" is correct.

An increase in the concentration of greenhouse gases, like carbon dioxide, in the atmosphere can increase the temperature on Ear
mart [117]

Answer:

Global warming intensifies water cycle

Explanation:

Global warming can dramatically intensify the water cycle because this phenomenon is associated with an increase in temperature, thereby a higher amount of water is evaporated into the air and a higher amount of ice is melted at the poles. Warmer atmospheric air will have a higher amount of water vapor, increasing the frequency and intensity of rainstorms. In consequence, global warming can significantly increase the probability of flooding in coastal communities.

Tasting involves many different cell-signaling processes that ultimately generate nerve signals transduced by membrane depolariz
vovikov84 [41]

Answer:

B.  Sodium ions directly enter the cells, indicating the signal is transduced by an ion channel.

D. Sweet utilizes the GPCR signaling pathway, activating phospholipase C.

Explanation:

The taste received by the taste buds is processed through different channels

a) The Sweet, bitter, and umami tastes  are transduced by the GPCR (G-protein-coupled receptors) signaling pathway

b) Sour taste reaches the taste bud through the acidification of acid-sensitive membrane proteins with in the taste cell

c) The epithelial sodium channels in the renal tissues directly takes up the salty taste

Hence, option B and D are correct

Compared to small cells large cells have more trouble
Talja [164]

large cells have more suface area so it will take the fluids and molecules entering a longer time. So they will have trouble moving needed materials in and waste products out. Hope this helped have a great day! :)
