Phloem
The pathway that the viruses would most likely follow on first entering the plant is D. PHLOEM.
The phloem, whose purpose is to transport food from the leaves to the plant, is used as the pathway to spread the virus throughout the plant. The manifestation of aphid transmitted virus is the yellowing, mottling, or curling of leaves and the stunted growth of the plant.

Answer:
The right order is 3, 1, 2.
Explanation:
The most superficial layer is 3, which describes the Cornea. This layer, which is first hit by light, is made of transparent and resistant fabric. It protects the eyeball from trauma and contamination and helps shape the globe and refract light.
Then, the layer described as 1 is the pigmented part that has melanocytes, which may be the uvea that consists of the whole of the iris, choroid membrane and ciliary processes.
Finally, the deepest layer in this question describes the lens, which is a gelatinous biconvex lens. This important structure enables the eye to focus on objects.
Answer:
C. IBIB
D. IBiO
Explanation:
The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.
So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.
However, if a person has blood group O it means that he has genotype IOIO.
So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.
The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.
Similarly, Eric's grandmother Tricia has genotype B which means that she can have genotype both IOIB and IBIB respectively.
Therefore, both C and D are correct options.
The answer is Archaeopteryx.
Archaeopteryx is a bird-like dinosaur. It lived in an archipelago of islands that later formed Europe 150 millions of years ago. It was a raven-size. It had a feather and wing and was able to fly. Despite that, it was more similar to the dinosaurs than the modern birds, with its sharp teeth, claws, and skeleton. Nevertheless, it<span> represents transitional fossil between reptilia and birds.</span>
