RNA viruses can copy themselves which is harder for scientists to give an accurate conclusion to solve them.
Answer:
Natural selection is one of the mechanisms by which an organism evolve. In the natural selection when the trait of an organism allows the organism to grow and reproduce in an environment and nature selects it, it is then passed on to the generations and become permanent.
Artificial selection is also one of the mechanism of evolution in which instead of nature, the selection is made by humans like the breeding experiments on dogs and plant crops.
The artificial selection and natural selection are interlinked as in the artificial selection the trait selected by the humans were also selected by nature like the case of crops, the crossing between desired plants produced results which were useful to the humans but grew and reproduced only when the environment selected it to grow and reproduce.
A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE
B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
<h3>What are Euglenas</h3>
Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.
The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed to grow exponentially for several weeks.
Hence we can conclude that Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

Answer:
D. Patterns of human development are similar to those of other vertebrates.
Explanation:
In the attachment above it is observed that the fetal developmental stages appear similar. The pictures represented different fetus of vertebrates such as man, tortoise, Dog, Chick.
During close observation it is noticed that Patterns of human development are similar to those of other vertebrates.
It is distinctive, widespread, abundant and limited in geologic time. Because most fossil<span>-bearing rocks formed in the ocean, the major </span>index fossils<span> are marine organisms. That being said, certain land organisms are useful in young rocks and in specific regions.</span>
