Which Best Describes The Bacteria Discovered By The Scientist Dr Lange? Lange discovers a colony of bacteria living in an extremely acidic environment. While observing the colony, she finds that the bacteria are autotrophs. Which best describes the bacteria discovered by the scientist? They are probably archaebacteria Which characteristic describes all bacteria quizlet? – They
Why Is Protista No Longer A Kingdom? Protista polyphyletic: some protists are more closely related to plants, fungi or animals than they are to other protists; it was too diverse, so it no longer a single kingdom. Why are protists no longer classified in their own kingdom? Explanation: Because Protist has many organisms that are
Which Of The Following States That All Organisms Are Composed Of Cells? The unified cell theory states that all living things are composed of one or more cells. Cells are the basic unit of life. Another part of the cell theory is that all cells come from pre existing cells. What are all living cells
What Is The Role Of DNA Replication? DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. What is
What Is The Difference In Protein Synthesis Between Eukaryotes And Prokaryotes? In eukaryotes, protein synthesis occurs in the cytoplasm. In prokaryotes, protein synthesis begins even before the transcription of mRNA molecule is completed. … Therefore mRNA processing is not required. The primary mRNA transcript in eukaryotes undergoes processing and splicing to change into a functional
Do Protists Only Have RNA? As previously mentioned, all protists have a true nucleus. The nucleus is like the central command center of the cell and contains crucial genetic information (DNA and RNA) needed for growth and reproduction. It is enveloped safely in a nuclear membrane and suspended within a jelly-like substance called cytoplasm. Do
Are Protists Animals Plants Or Fungi? Many diverse organisms including algae, amoebas, ciliates (such as paramecium Why are protists not plants animals or fungi? Multicellular protists like seaweed have neither highly specialized tissues nor organs, which distinguishes them from true plants or other eukaryotes. Many protists do not have much in common with each other;
Are Protists Eukaryotic? Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes. Why are protists considered eukaryotes? Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very
Are Prokaryotes Older Than Eukaryotes? Prokaryotes have existed on Earth since at least 3.8 billion years ago. Eukaryotes are organisms with a nucleus. The oldest evidence of eukaryotes is from 2.7 billion years ago. What came first prokaryotes or eukaryotes? The first, simplest life forms were prokaryotes—organisms, like bacteria, that don’t have a nucleus. Prokaryotes
Do Prokaryotes Have A Nucleus Yes Or No? Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes. Do prokaryotic and eukaryotic cells have a nucleus? The primary distinction
