#4 i believe is Atmosphere. Geosphere is actually all the land of the earth
#5 is Lithosphere
#6 is Geosphere
<span>This is a positive feedback. These episodes make the next glacial period even more severe and long-lasting than the one prior. This is due to the reflectance of the surface of the land having a positive relationship with how much energy is absorbed: as the reflectance increases, absorption decreases, and the glacial period increases in severity.</span>
It has to be C. Vascular bundles arranged in a ring. This is my chosen answer because only monocots have fibrous roots, but dicots have one main root called a taproot. Monocots have floral parts in multiples of three, but dicots have four or five. Monocots have parallel veins in leaves but dicots have branching veins. So the answer is C. Vascular bundles arranged in a ring. Hope this helps.
Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:
- The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.
Explanation:
<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .
Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :
- Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
- Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).
