The answer is C. Nucleotide
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
Answer:
Tolerance to heat, light and parasite.
Explanation:
Characteristics of tolerance to heat, light and parasite are the three reasons that might use a higher percentage of Nguni on the sector of livestock farmers in South Africa in 2003. The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.
<u>Answer:</u>
If calcium were removed from the tissue then the polarity will be established within the cell but polarity will be lost in the tissue.
<u>Explanation:</u>
- Cell polarity is the cellular components like cytoplasm, plasma membranes and other various cell organelles in the asymmetric order.
- The coordinated arrangement of this cell polarity in tissue plane is called as planar cell polarity (PCP).
- Calcium is the major component in the tissues that helps in formation of bones and other parts of body, if it is removed then the polarity will not be seen in the tissue, but in the cell the polarity will be established.
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.
