The two major groupings within the animal kingdom are?
The two major groupings within the animal kingdom are invertebrates (animals without a backbone) and vertebrates (animals with a backbone). Invertebrates make up the majority of animal species and include insects, worms, and mollusks, while vertebrates include mammals, birds, reptiles, amphibians, and fish.
What is an example of a major organic compound?
One major organic compound is glucose, which is a simple sugar commonly found in fruits and plants. Glucose is a key source of energy for living organisms and plays a vital role in cellular respiration.
How many major group of pathogenic organisms are there?
six
What reason did approximately 542 million years ago was selected to be the end of Proterozoic eon and the beginning of the Paleozoic era?
The transition from the Proterozoic eon to the Paleozoic era, approximately 542 million years ago, is marked by the appearance of diverse and complex life forms during the Cambrian explosion. This period saw a rapid increase in the diversity of multicellular organisms, including the first representatives of many major animal groups. The significant geological and biological changes, including the development of hard-bodied organisms and the establishment of complex ecosystems, define this boundary and signify a major shift in Earth's biological history.
What are 2 examples of carbohydrates in living organisms?
Two examples of carbohydrates in living organisms are glucose and cellulose. Glucose is a simple sugar that serves as an important energy source, while cellulose is a complex carbohydrate found in plant cell walls providing structural support.
How do protists differ from major groups?
Protists are a diverse group of eukaryotic organisms that do not fit into the plant, animal, or fungi kingdoms. They are unicellular or simple multicellular organisms that can be autotrophic or heterotrophic. Major groups such as plants, animals, and fungi are more complex multicellular organisms with distinct structures and functions.
What are the major grouping of organisms name them from the simplest to the most complex?
"yea yea yea"... "siencie is stupid i mean get over it already we now that is how everyone feels" haha lolzzz hah NOOO!! science is aamzing i mean u find a lot out becasue of it i mean science suckXS!@@!@!@
The three major subdivisions of all organisms?
The three major subdivisions of all organisms are Archaea, Bacteria, and Eukarya. These groups are based on differences in cell structure and biochemistry. Eukarya includes organisms with complex cells, such as plants, animals, fungi, and protists, while Archaea and Bacteria consist of simpler organisms with prokaryotic cells.
What are the different islands of the Philippines?
The 7,107 islands of the Philippines are grouped into three major island groupings: Luzon, Visayas and Mindanao.
Were the any major events in the precambrain period?
During the Precambrian period, Earth's atmosphere and oceans were forming, and the first simple life forms like single-celled organisms appeared. There were no major events like the complex life forms and multicellular organisms evolved later during the Paleozoic era.
What is animal phyla?
Phyla is plural for Phylum. It is used in animal taxonomy and is the category between kingdom and class. Animals in the same phylum have the same degree of developmental similarity. There is a total of 36 animal phyla that all animals fall under and the largest phylum is Arthropoda.
What changes were necessary in earth's atmosphere to allow complex organisms to evolove?
During the few billion years following the appearance of cyanobacteria, oxygen became a major gas in Earth's atmosphere. The ozone layer in the stratosphere also began to develop, shielding Earth from ultraviolet rays. These major changes in the air allowed species of single-celled organisms to evolve into more complex organisms.
What are the two major groups of organisms?
The two major groups of organisms are prokaryotes and eukaryotes. Prokaryotes are simple, unicellular organisms that lack a nucleus, while eukaryotes are more complex organisms with cells that contain a nucleus and other membrane-bound organelles.
What are organisms that carries out photosynthesis called?
We call them photosynthetic organisms. Plants are the major organisms.
The two major groupings within the animal kingdom are?
The two major groupings within the animal kingdom are invertebrates (animals without a backbone) and vertebrates (animals with a backbone). Invertebrates make up the majority of animal species and include insects, worms, and mollusks, while vertebrates include mammals, birds, reptiles, amphibians, and fish.
Major components of an ecosystem?
Are Organisms.
Do T cells have major histocompatibility complex (MHC) molecules?
Yes, T cells have major histocompatibility complex (MHC) molecules.
