Answer:

Glomar Challenger studies about the "age of rocks in various places in the ocean" in 1968

Explanation:

Glomar Challenger was a "deep sea research vessel" for marine geology and oceanography studies.

The vessel set out in 1968 on a "Deep Sea Drilling Program" in the Atlantic Ocean.

Samples were collected from various drilling locations and the study and analysis of these samples enabled the study of plate tectonics.

These samples also provided more information related to the rocks in oceans.

The vessel drilled cores containing rock salt, gypsum, anhydrite and several other evaporating minerals.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptat
expeople1 [14]

Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.  

In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.  

These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.

Translation ends when
Y_Kistochka [10]

<span>Translation

</span>Remember that transcription happens in the nucleus as it changes from DNA to mRNA.  In translation,
    the mRNA first has to leave the nucleus and go into the cytoplasm of the cell.  The process of translation actually occurs in the cell’s ribosomes.

<span>
</span>The process of translation uses the genetic code on the mRNA strand to direct the construction (making) of a protein molecule. <span>
</span>1.  A ribosome attaches to an mRNA molecule in the cytoplasm.<span>
</span>2.  As each codon passes through the ribosome, tRNA molecules bring the matching amino acids into the ribosome.  Each tRNA has a set of 3 unpaired nitrogenous bases called an anticodon which matches up with the codon coming through the ribosome.  So one end of a tRNA has an anticodon and the other end carries the amino acid which is how the code is translated.<span>
</span>3.  The ribosome and the rRNA molecules it contains attach the amino acids together as they are being translated.  The protein chain will keep growing until the ribosome reaches the stop codon on the mRNA.  At that point, translation is done and the ribosome lets go.


Hope this helps!!!

Natural selection is the process by which favorable traits tend to increase in frequency over time.
Nana76 [90]

Answer: The statement is true

Explanation:

Natural selection, as its name implies refers to the choice of certain favorable traits such as resistance to diseases, bigger fruit size etc above lesser favorable traits such as easy susceptibility to diseases, small fruit size etc.

Hence, nature allows the traits that will help living organisms survive best in their environment to be passed down to new offsprings while it eliminates all other traits.

Thus, the statement is true
