Selective breeding is also called artificial selection, it is technique that involves choosing parents based upon desired traits or develop particular phenotypic traits. It is used in improving the racing abilities of horses, such that if two fast horses were mated, the offspring may inherit the characteristics that lead to the ability to run fast.
Answer:
<u>thermometer</u>
Explanation:
<em>A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.</em>
Answer:
PEPTIDE BOND.
Explanation:
Amino acids can link with each other through a peptide bond to form a protein or polypeptide .
this is a condensation reaction that involves the elimination of water molecule.i.e a H2O molecule is produced in this reaction.
the peptide linkage occurs when the OH group of acidic side of one amino acid reacts with the H-atom of the other amino acid and C-N link to form a bond called a PEPTIDE BOND.
Answer:
The answer is C.
Explanation:
The example process given in the question is describing the creating of a cDNA Library. cDNA or Complimentary DNA is copy of the DNA that is taken from a messenger RNA (mRNA), which is what is done with the reverse transcriptase. And the process described as cloning the resulting DNA into plasmids is the part where the library is created. The resulting DNA is put into host organisms and stored there for further investigation or use.
I hope this answer helps.
Answer:
They remain in an environment,even as more competitive species arrive
Explanation:
Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.
Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:
- They facilitate environmental change, making an environment more habitable for other species.
- They tolerate a wide range of environmental conditions.
- They are capable of colonizing a barren environment, as in primary succession.
However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.
