Earth is the only place in the universe where life is known to exist. The planet's lifeforms are sometimes said to form a "biosphere". This biosphere is generally believed to have begun evolving about 3.5 billion (3.5×109) years ago. The biosphere is divided into a number of biomes, inhabited by broadly similar flora and fauna. On land, biomes are separated primarily by latitude. Terrestrial biomes lying within the Arctic and Antarctic Circles are relatively barren of plant and animal life, while most of the more populous biomes lie near the Equator.

From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air). Earth is the only place where life is known to exist. This biosphere is generally thought to have evolved beginning, through a process of biogenesis or biopoesis, at least some 3.5 billion years ago.

The sum of and interaction between all living beings.The biosphere is the global ecological system integrating all living organisms and their relationships. The interaction with the elements of the lithosphere, hydrosphere, and atmosphere is also included. The biosphere, we know today, has evolved for 3.5 billion years.The biosphere covers most of the planet and stretches from the deep ocean to the highest mountain tops. Microorganisms also live deep beneath the surface of the Earth.The biosphere is divided into different biomes. Each of these consist of species that are related in their ability to cope with a specific climate. Biomes are separated by latitude. Arctic and Antacrtic biomes are vastly different from tropical biomes, for example.Climate change influences the distribution of these biomes and to some extent displaces them.The biosphere is an important reservoir in the carbon cycle and has a very significant impact on climate through release and removal of CO2 from the atmosphere.

Which occurs during translation

RideAnS [48]

Answer:

Translation occurs in a structure called the ribosome, which is a factory for the synthesis of proteins. ... Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.

What is the primary product of light-independent reactions?

Alina [70]

The correct answers are;

A.) High energy sugars

A) ATP

The light-independent (dark) reactions are chemical reactions of photosynthesis which occurs within the stoma in plant chloroplast. These reactions use the products of light-dependent reactions which are ATP and NADPH with some enzymes (such as RuBisCO) to carry out its processes. Carbon dioxide and other compounds are converted to produce high energy sugars (glucose) which is used by the plant.

Glycolysis is the cellular degradation of the simple sugar (glucose) to produce pyruvic acid (also known as pyruvate), and ATP (adenosine triphosphate) is used as an energy source.

The sentence which is true or a fact about the virus is the sentence in letter B. Viruses can reproduce only within other cells. Viruses are intracellular obligate parasites they can not replicate or express the genes with out living host. 
viruses are acellular so they have to rely on host cellular machinery for reproduction. 
viruses doesnot contain any enzymes for reproduction

Compare and contrast the extracellular matrix of animals and the cell wall of plants. Consider their functions and the types of

mario62 [17]

Answer:

The plant cell wall is strengthened by the molecular structure of cellulose. Cellulose is made up of ß-glucose arranged upside down, this arrangement aided hydrogen bonds between the hydrogen ions of the hydroxyl group and oxygen of the of the ring of same betta -glucose.

The aggregation of the hydrogen bonds give bundles of strong tensile strength of cellulose called the microfibrils (of 60-70 celluose molecules).They are held together in bundled called fibers.These is the source of plant cell walls strength.

Collagen is the main extracellur matrix (EM) in animal cells.It is a glycoprotein made up of 25%of body protein of animals.Each collagen molecule is made of helix shaped ,three polypeptide chains, wound around each other to form triple helix.The bonds holding helix together are hydrogen and covalent bonds.

Each triple helix is attached to adjacent collagen molecule, parallel to it. The covalent bonds formed a cross link which held the collagen molecules together forming FIBRILS. This gives flexibility to collagen, while maitaing strong tensile strength. This is what is responsible for the structural strength of cell membrane .

.The EM,is futher reinforced with carbohydrate molecules(proteoglycans) which aided in water movements by osmosis following sodium movements into the matrix.
