1.Earth is the only planet known where intelligent life exist.

2.It lies in the circumstellar habitable zone (CHZ). CHZ is defined in the image given below.

3. Earth has a unique magnetic field which protects the earth from the harmful solar winds. These solar winds played a role in transforming venus into hell.

4. Earth has Van Allen radiation belts which protects it from cosmic rays.

5. Our large neighbour Jupiter protects is from many comets and asteroids that come from the keiper belt and Oort cloud.

6. Earth's atmosphere is favorable to support life on earth. This atmosphere consists of different gases in adequate amount. If the percentage of gases would differ then life on earth may face serious consequences.

<h2><u>A</u><u>nswer:</u></h2>

<u>Translation:</u> process of protein formation is called translation .

In the process of translation, a cell reads information from a molecule called a messenger RNA  and uses this information to build a protein.  Translation involves “decoding” a messenger RNA  and using its information to build a polypeptide, or chain of amino acids .

Translation involve three major steps

• Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.

• Elongation ("middle"): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a poly peptide chain.

•Termination ("end"): in the last stage of translation, the finished polypeptide is released to go and do its job in the cell.

<u>Organelles involve in translation:</u>

Ribosomes: main process of translation occour at ribosomes.

Rough endoplasmic reticulum: ribosomes are located on rough endoplasmicreticulum .it bound proteins in the vesicles.Vesicles containing proteins are budded off into cytoplasm and move toward golgi apparatus for further modification .

Golgi apparatus: synthesisezed proteins are not functional . In golgi apperatus they are further modefied and processed and stored for a short time and then released toward destination.

Marta_Voda [28]

Answer:

The forces on a thrown ball after it leaves the thrower's hand are the force of gravity and possibly the force of air resistance.

Explanation:

The force of gravity at the surface of the Earth is the gravitational acceleration at that location (9.8 meters per second per second) times the mass of the ball.
