<span>Metabolism is the
chemical reactions that take place inside a living organism. The reaction
occurs in the cells. Digestion can be
the best association to metabolism. The metabolic system recognizes which
substances can be nutritious or poisonous. In order to complete this process,
water is needed. The chemicals are
dissolved in water and transported. Without water, no reaction can take place.</span>
Metabolism is considered
as the set of life-sustaining chemical reactions within the living organism’s
body cells.
Answer:
D) Heterotrophs can make their own food
The greenhouse effect occurs when rays enter our atmosphere and are reflected from the ground up. They get changed during their voyage through our atmosphere and they change in such a way that they can't leave the atmosphere anymore. Then they stay inside and heat up the planet which causes thing like global warming. That's what the greenhouse effect is.
Answer:
The fill in the blanks are as follows:
a-unicellular prokaryotes that live in dust are Eubacteria.
b-unicellular eukaryotes that live in pond water are Protista.
c-multicellular eukaryotes that live all over the planet and consume food are Anamalia.
d-unicellular prokaryotes that live in volcanic ash and other inhospitable environments are Archaebacteria.
e-multicellular eukaryotes that have cell walls and are heterotrophic are Fungi.
f-multicellular eukaryotes that have cell walls and are autotrophic are Plantae.
Explanation:
By looking for the definitions of the different types of eukoaryotes and prokaryotes, the fill in the blanks are correctly completed.
Answer:tailing at 3' end protects mRNA from attack by 3' exonuclease and 5' capping is useful for recognition of mRNA
Explanation:
The mRNA formed and released from the DNA template is known as primary transcript. In mammalian system, it undergoes intensive modification to become the mature mRNA.
Post transcription processing includes removal of Introns, splicing of exons, poly-A tailing at 3'end and capping at 5' end.
The Poly-A tailing at 3' end occurs in the nucleoplasm, the 3' end is polyadenlated involves with 20-250 nucleotides long. This tail protects mRNA from attack by 3' exonuclease activity
5' end capping end also is done in the nucleus. The cap is useful in recognition of mRNA by the translating machinery.
