Thermal stress weathering, or insolation weathering as some of you might call it.
Answer:
C. The cells in these two areas have different functions.
Explanation:
The plant tissues are classified into three major systems: vascular, epidermic, and root systems. The vascular system is formed by tissues referred to as xylem and phloem. The epidermis is composed of superficial tissues that cover plant organs (i.e., leaves, stem, roots, etc). Finally, the root system is formed by tissues whose function is to supply to other plant tissues and store nutrients. Moreover, the plant tissues are also classified into meristematic and permanent tissues. In this case, it is reasonable to suppose that structurally different plant cells that are located at different areas of the plant will have distinct functions.
In animals, an important function of enzymes is to help digest food. Digestive enzymes speed up reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use... hope this helps
Answer:
Active transport occur in the uphill direction where passive transport occur in the downhill direction this is the principle comparison between passive transport and active transport.
Explanation:
Passive transport involves simple transport mechanism such as diffusion,osmosis and facilitated diffusion that help in the transport of molecule across the membrane from high concentration region to the region of low concentration untill equilibrium is reached. No additional energy is required to carry out passive transport. oxygen, carbon dioxide,water, glucose molecule are transported by passive transport mechanism.
Active Transport involves various ion channels which helps in the movement of molecules from low concentration region to the high concentration region .Additional energy in form of ATP is required to stimulate the active transport. Various ions such as Na+,K+, Ca2+, amino acids are transported by active transport.
Answer:
D. Adrenaline
Explanation:
Adrenaline hormone is secreted by adrenal medulla during stressful conditions. The hormone is involved in preparing the body for stressful conditions by intensifying the sympathetic response.
If a person is chased by a dog, the adrenaline hormone is released from the adrenal medulla. The hormone triggers the preganglionic neurons of the sympathetic division of the autonomous nerve system to generate the flight or flight response.
Adrenaline increases the heart rate, blood pressure, and blood flow to skeletal muscles and adipose tissues. The hormone also triggers the dilation of airways and increases the blood levels of glucose and fatty acids.
