WITH GUARANTEED ACCURATE

ANSWERS

Taxonomy - correct answer ✔✔The classification of organisms Aristotle - correct answer ✔✔Who was the first to classify organism as either plants or animals Linnaeus - correct answer ✔✔The father of taxonomy. He used kingdom, phylum, class, offer and species to classify organisms. Fossil record - correct answer ✔✔Scientist will determine the amount of radioactive decay in a fossil to "date" the specimen. Anatomy - correct answer ✔✔Scientists compare the bone structure of organisms to see if they are related. Embryonic development - correct answer ✔✔Scientists compare organism in early development to see if there is a relationship between. Biochemistry - correct answer ✔✔Scientists compare molecules in living things to see how closely related they are DNA - correct answer ✔✔scientist can squire DNA in living things to help compare organisms and classify them. Ex humans DNA is 98% similar to chimpanzees Nomenclature - correct answer ✔✔Genus name then species name. The genus name is always capitalized. Lytic cycle - correct answer ✔✔Attachment, entry, replication, assembly, lysis and release.

Chemoautotroph - correct answer ✔✔Make their own food using chemicals Photosynthesis - correct answer ✔✔Make their own food using sunlight Parasite - correct answer ✔✔Obtain food from another organism Saprophyte - correct answer ✔✔Obtain food from decaying material Cocci - correct answer ✔✔Round shaped body type of bacteria Bacilli - correct answer ✔✔Rod shaped body type of bacteria Spirlli - correct answer ✔✔Spiral shaped body type of bacteria Prokaryotic - correct answer ✔✔Basic cells with no nucleus or organelles Eukaryotic - correct answer ✔✔Has cells with DNA and a distinct nucleus Virus - correct answer ✔✔A piece of genetic lateral surround by a protective coat. These are not considered living. Kingdom bacteria - correct answer ✔✔Cell type: procaryotic Cell wall: yes Body form: unicellular Nutrition: photo/chemo/absorp (Herero) Nervous system: no Reproduction: asexual Locomotion: some Ex: bacteria

Kingdom Archea - correct answer ✔✔Cell type:Prokaryotic, cell wall: some Body type:unicellular and multi Nutrition: heterotroph Nervous system: No Reproduction:asexual, locomotion: some Kingdom Protista - correct answer ✔✔Cell type: eukaryotic Cell wall: yes Body form: multicellular Nutrition: heterotroph Nervous system: none Reproduction: sexual and asexual Locomotion: present Ex: algae Kingdom fungi - correct answer ✔✔Cell type: eukaryotic Cell wall: yes Body form: multicellular Nutrition: absorption Nervous system: no Reproduction: Sexual and asexual Locomotion: no Ex: mold, yeast, mushroom Plante - correct answer ✔✔Cell type: eukaryotic Cell wall: yes Body form: multicellular Nutrition: photosynthesis Nervous system:no

Reproduction: sexual and asexual Locomotion:no Ex: moss, fern, flowering plants Kingdom animalia - correct answer ✔✔Cell type: eukaryotic Cell wall: no Body form: multicellular Nutrition: Nervous system: yes Reproduction: sexual Locomotion: yes Ex: sponge, jellyfish, worm, human Vascular plants - correct answer ✔✔Tissue in these plants to provide support and Aids in transport. Has true roots, stems and leaves Non vascular plants - correct answer ✔✔These plants Rely on diffusion for transport. Lack true roots, steams and leaves Bryophyta - correct answer ✔✔Non vascular Depends on water Dominate generation Gametophyte Depends on water to move sperm & eggs Ex: mossss Fern and Cellies - correct answer ✔✔Vascular Depends on water Dominate generation

Sporophyte Sperm used dee or water to fertilize Ex: fermion club Gymnosperms - correct answer ✔✔Vascular Doesn't need water Sporophyte Sperm is inside pollen, moved by wind Ex: for & pine trees Angiosperms - correct answer ✔✔Vascular No water needed Sporophyte Seed is protected by coat Ex: flowering,apple trees, roses, grass

• They are the most successful plant

• animals and insects hell pollinate them •brightly coloured flowers attract insects •smell of nectar attracts insects
• seed coat protects seeds Binary fission - correct answer ✔✔ASEXUAL 1.Parent fell gets bigger and makes a copy of its DNA

2. The cell stretches and two DNA pieces move to opposite sides
3. A septum forms between the two pieces of DNA
4. It separates and two new daughter cells are made Conjunction - correct answer ✔✔SEXUAL
5. Two parents form a pili

2. DNA is exchanged
3. The result is a genetically different daughter cell Invertebrates - correct answer ✔✔•Lacking a backbone •Roughly 97% of the animal kingdom Vertebrates - correct answer ✔✔•Having a backbone or spinal column •Roughly 3% of the animal kingdom Archae bacteria - correct answer ✔✔Unique bacteria that live in extreme environments Asymmetric - correct answer ✔✔Irregular shape. A organism cannot cut into two matching halves. Radical - correct answer ✔✔A line can be drawn anywhere through the central axis of a organism from top to bottom or front to rear. This cut divided it in half Bilateral - correct answer ✔✔There is only ONE line that divides the body in half. Mirror images of each other Porifera - correct answer ✔✔The phylum in which organisms that have bodies full of pores allowing water to circulate through them EX: sponges Cnidaria - correct answer ✔✔The phylum in which Organisms that have tentacles with stinging abilities EX: jellyfish Platyhelminthes - correct answer ✔✔The phylum in which the organisms are relatively simple bilaterian, unsegmented, soft-bodied invertebrate EX: Flatworm

Annelida - correct answer ✔✔The phylum in which the organisms can live in a variety of habitats like water Ex: leech, earthworm Mollusk - correct answer ✔✔The largest marine phylum. They are highly diverse in anatomy, size and behaviour. Ex: sea snail, squid Arthropoda - correct answer ✔✔The most successful phylum because they have a exoskeleton, a segmented body, a advanced sensory system (compound eyes) and jointed appendages.They can live in variety of habitats and can fly EX: insects Germ layers - correct answer ✔✔an inner layer called endoderm, and an outer layer, called ectoderm. Coelom - correct answer ✔✔The body cavity that holds the internal organs of higher invertebrates and vertebrates Capsid - correct answer ✔✔Protein coat outside of a virus Vascular tissues - correct answer ✔✔The purpose of this structure is to transport water and dissolved substances. Organisms who don't have this depends on diffusion for transport
