Extinction of species reduces the number of different species in ecosystems, hence lowering the diversity of living things.
Answer:
D. the nucleus contains the protons and neutrons which takes up most of the mass of the atom
Explanation:
Answer:
Global Warming is simply the long-term rise in temperature of the Earth's core, which inevitably would effect the climate systems of the Earth.
The Green House Effect is the natural process that warms the Earths surface.
Explanation:
The Green House Effect--> When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back into space and the rest is absorbed and re-radiated by the greenhouse gases.
<u>Answer</u>:
The organic chemicals that helps cell membranes to conserve the internal fluids are phospholipids.
<u>Explanation</u>:
Phospholipids are used to form plasma membrane of the cell. Plasma membrane surrounds the cell contents like various cell organelles, nucleus, ribosomes and proteins. A phospholipid molecules is made up if a polar head containing a phosphate group and the two non-polar tails made of long chains of hydrocarbon of fatty acids.
The another name for plasma membrane is phospholipid bilayer. The polar head is hydrophilic that interactes with polar environment while facing outside the bilayer while the non-polar tail is hydrophobic in nature which makes the internal hydrophobic region of cell membrane which faces inside the bilayer.
A transference RNA (tRNA) is an adapter molecule that decodes a codon messenger RNA (mRNA) during the synthesis of a polypeptide chain. These molecules (tRNAs) play a fundamental role during translation.
- If a tRNA had an AGC anticodon it could attach a codon having the sequence UCG.
- During translation, tRNAs act at specific sites in a ribosome to synthesize a polypeptide chain (i.e., a protein) from an mRNA sequence.
- The anticodon of the tRNA binds by base complementary to a triplet of nucleotides or 'codon' in the messenger RNA (mRNA) during protein synthesis (i.e., translation).
- According to the base complementarity rules, in RNA, Adenine always pairs with Uracile (Thymine in DNA), whereas Guanine always pairs with Cytosine.
