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>
Answer:
Binary Fission
Explanation:
Single-celled organisms reproduce using binary fission. For example, bacteria are single-celled organisms. They reproduce using binary fission. Binary fission is the process of an organism splitting itself into two parts, with the parent's DNA in the new part.
Good Luck!
The other name for unicellular organisms that dominated Earth up to the Precambrian time is called D. prokaryotes. Eukaryotes are different from prokaryotes such that prokaryotes are unicellular while eukaryotes are multicellular
Phenylalanine hydroxylase (PHA) performs an enzymatic function during the conversion of phenylalanine, to tyrosine. Existing naturally in several types of foods, for instance, breast milk, PKU is an essential α-amino acid and one of the plethora of amino acids used in the formation of proteins. Phenylalanine exists in three forms; L-phenylalanine, D-phenylalanine (mirror image of L-phenylalanine), and DL-phenylalanine which is a typic combination of D and L-phenylalanine, and unlike D and L- phenylalanine, is not found in foods. On the other hand, tyrosine, apart from being a derivative of phenylalanine, is a non-essential amino acid that forms part of the list of amino acids utile during the constitution of proteins. Ordinarily, lack of PAH leads to the accumulation of phenylalanine (the phenylalanine is not converted to tyrosine) leading to the development of a disease called Phenylketonuria (PKU).
Hope this helps!
