Answer:
(B) resemble structures formed by bacterial communities that are found today in some shallow marine bays.
Explanation:
Extant stromatolites represent real "living fossils" for they are decendents of ancient forms that are associated with one of the first living forms on earth. Particularly, stromatolites are real bacteria communities where the autotrophic organism of the community are represented by cyanobacteria, which live along with heterotrophic bacteria. This clearly indicates that fossilized stromatolites points to bacteria (prokaryotes) as the first living things on earth (dated with not less than 3.5 billion year old)
Nowadays, stromatolites with cyanobacteria allows to reconstruct and understand fossilized forms. These current structures live in shallow marines ambients (e.g. Australia) but also in continental salt flats (e.g. Argentina) where few others bacteria can survive to these extreme conditions (high light exposure and salt concentration).
Answer:
Input- Carbon dioxide, Water, Sunlight.
Output- Oxygen and glucose
Plants take in carbon dioxide through pores in their leaves. They take in water through their roots and the leaves capture the sunlight by using chlorophyll.
Explanation:
Answer:
Top to bottom: 5, 3, 2, 4, 1
Explanation:
I'll take a shot! Here I go!
5 (Sun) = top; we get all our energy from the sun
Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis
Then 2; we're talking about herbivores that eat plants, right?
Then 4; these are probably~ carnivores
Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem
Have a great day!
I found this info if this is what you need link http://www.answers.com/Q/What_are_the_functional_groups_of_amino_acids
Two functional groups are found in all amino acids. These functional groups are the
amino group
(-NH2) and the
carboxyl group
(-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.
Function of amino acids?
Heat and Energy, Growth, To defend against disease, and to Repair bodily cells are the functions of amino acids/ proteins.
Amino acids contain a carboxyl group?
Yes, amino acids contain: 1) an amino group (-NH 2 ) 2) a central carbon and variable side group 3) a carboxyl group (-COOH)
What is the function of amino acids?
Amino acids are nitrogen-containing molecules that serve vitalfunctions in your body. Twenty-two amino acids occur in nature, and20 of these are incorporated into proteins and other moleculeswithin the cells and tissues of plants and animals. According toscientists at the University of Arizona, your body can synthesize10 of the amino acids you need, while the other 10 must be acquiredfrom your diet. Amino acids that cannot be produced within yourcells are called essential amino acids. http://www.livestrong.com/article/426255-what-is-the-function-of-amino-acids-in-the-human-body/
What is the amino group on an amino acid?
The amino group is present at one end of the amino acid and is represented by the chemical formula NH 3 The region on the amino acid that contains the amino group is called the amino terminal
Amino acid function?
Amino acids are basically known as the building blocks of protein.The function of an amino acid is primarily to build proteins.
Explanation:
animals have specific parts of the body adapted to survival in a certain environment among them are webbed feet,sharp claws, whiskers, sharp teeth,long beaks,wings and hooves and in most aquatic animals swimming is a must.
