Yes, natural selection can create different species because over time one species will turn into subspecies and as soon as one subspecies cannot breed with the other subspecies they are no longer the same species. Natural selection creates species through adaption and survival of the fittest, so yes natural selection can create different species.
Answer:
a. Exoskeleton made of chitin
Explanation:
Arthropods are invertebrate animals with articulated locomotor organs, which is the main characteristic of this phylum. The articulated paws allow the animal to perform various movements, very well defined and elaborate. This feature gives these animals not only efficient locomotion, but also aids in their defense and food capture.
They have another striking feature as well, which is the diversely segmented body, but always covered by a chitin cuticle, which represents its exoskeleton. Some have a calcareous shell outside the chitinous exoskeleton, such as crustaceans.
The Dermis is made of dense irregular connective tissue along with nervous tissue and gives the skin its strength and elasticity.
Answer:
850
Explanation:
rate of population increase = birthrate - death rate + immigration - emigration
= 1400 - 600 + 100 - 50 = 850
The probability of two independent events occurring together is the Quotient of the probability of each event occurring separately.
