Explanation:
Amphibians are group of animals that live a double life; one in water with gills and the other on land with lungs (at maturity). They include frogs, newts, salamanders etc.
Reptiles ( meaning to creep under shadow of darkness) are group of animals that possess scales. They include snakes, crocodiles, lizards etc.
Reptiles and amphibians are distantly related but share some traits including:
1. They are both poikilothermic (cold-blooded) animals i.e. their body temperature is dependent on that of the environment's.
2. They both lay eggs externally, although that of amphibians is fertilized after being layed
3. They both possess lungs for gaseous exchange, although, amphibians use gills in water.
4. Both reptiles and amphibians belongs to Chordata i.e. they both possess a vertebrae column (backbone)
5. Most reptiles and amphibians make use of the same defensive and attacking traits as a pretty and predator respectively. They employ camouflage, biting and inflating of their body size.
Transport proteins (carrier proteins and channel proteins) allow substances into and out of the cell that cannot pass through the phospholipid bilayer (as they’re either to large, charged or not lipid soluble) by facilitated diffusion.
Specifically channel proteins allow ions into and out of the cell by creating a pore in the membrane in which they can move through with their concentration gradient
Answer:
Option C
Explanation:
Please see the image attached
In this image we can see that the Primate A is waking through the tree by using all its four limbs i.e rear and front limbs. Such primates have Arboreal quadrupedalism. Their hand and feet bend towards the direction of the curve of the support. They have long lever arms which provide gear ratio for grasping and greater leaping distance. However, their feet are also able to grasp.
Option C is correct
Prostaglandin similarity with hormones is in the effect they achieve by binding to the receptors. Their effects are mediated by paracrine or autocrine mechanisms. Another hormone characteristic is the ability to stimulate adenylate cyclase activity, producing cAMP as the second messenger.

On the other hand, prostaglandins differ from hormones in that they are not produced at a specific place but in many different places throughout the body. Also, the metabolic degradation of prostaglandins is very rapid.</span>
