Answer:

1. What is the relationship between body shape and the habitat where they are most commonly found?

2. What is the difference between toads having a thicker skin than frogs?  

Explanation:

<u>Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics</u>. Among their main differences are:

  • The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth.
  • Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body.
  • Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs.
  • Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.
  • Most toads are poisonous. In contrast in frogs, not all species are poisonous.

Given these observations, two questions that may arise could be:

1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.

2. What is the difference between toads having a thicker skin than frogs?  Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.

LIST AT LEAST THREE EXAMPLES OF HOW MICROBIAL PHOTOTROPHS ARE IMPORTANT CLINICALLY AND ENVIRONMENTALLY
zaharov [31]
Cyanobacteria are primitive organisms where chloroplasts are believed to be originated. These phototrophic organisms benefit the environmental and the clinical aspects because of their unique physiology. For instance, they contribute to energy attainment from sunlight which helps other organisms gain energy when this is consumed. Another is the contribution to biogeochemical cycles. And lastly, how these can aid in many medical discoveries and treatments.
