Answer:
1.a sequence of sugars, phosphates, and nitrogenous organic bases: Nucleic acid
2.a complex molecule containing the genetic code: DNA
3.a nucleic acid that participates in the synthesis of proteins: RNA
Explanation:
Nucleic acids are the biomolecules that are composed of a sequence of nucleotides. Each nucleotide has a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acid called DNA and RNA. DNA differs from RNA with respect to the pentose sugar and the presence of a thymine base. The sequence of the template DNA strand serves as a genetic code.
It is copied into the nucleotide sequence of mRNA during the process of transcription. The molecules of mRNA serve as a template for the synthesis of proteins when their nucleotide sequence is read in the form of genetic triplets.
Answer:
-The size of sheep olfactory bulb is two to three time larger than humans olfactory bulb.
-Sheep has strong sense of smell that helps the sheep to acquire food.
Explanation:
- The size of the sheep brain is much smaller than humans but sheep has well developed olfactory bulb than humans. The human brain is more circular in shape whereas sheep brain is more extended.
- The well developed olfactory bulb in sheep helps the sheep to find the food. Sheep has strong sense of smell due to large olfactory bulb. Sheep can easily find the location of food located farway from it as the sheep has strong sense of smell.
Answer:
The correct answer is B: Cohesion
Explanation:
<u>Cohesion</u> is the ability of water molecules to be strongly bonded together. This happens due to the polarity of water molecules. Since water is made up of two positive hydrogen ions that combine with one negative oxygen ion to form a hydrogen bond. Hence, the molecular structure of water enables hydrogen irons to attract oxygen ions that create a strong polar bond between water molecules.
Answer: Option A.
Electrons,carbon and energy.
Explanation:
Chemorganoheterotrophs are organisms that uses organic substrates to produce carbon needed for their growth and development. They derive their energy from oxidation and reduction of organic substances. The use the reduced carbon produced by autrotophs as as source of electrons, carbon and energy. Example is fungi that uses carbon as electron donor and source for carbon and energy.
