The correct answer is: marsupials.
Marsupials are actually defined by their ability to hold the young in the pouches, where they can be well protected. Some examples are Kangaroos and Koalas.
Other answers are wrong: for example, gymnosperms are plants, not animals.
Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
Options were missing from the question so the options are:
A.From the ice cube to the glass.
B. From the lemonade to the glass.
C. From the lemonade to the ice cube.
D. From the ice cube to the lemonade.
Answer: Option C
Explanation:
The main principle of heat transfer is that heat always flows from the hotter body to the colder body.
Here, the hotter body is thermos in which the lemonade was kept and the colder body is cooler in which the ice was kept.
During the mixing of lemonade into ice, the heat will from the hotter body to the colder body which means from lemonade to the ice. This process of heat transfer is unidirectional( hot body to cold body).
Hence, the correct answer is option C.
Diffusion is is like (spreading around), so it wouldn't smell that strong the further away you got... but you would still smell it
Answer: d. None of the above
Sustainable development involves the maintenance of human community with the adequate and judicious use of natural resources so that these resources will be available for future use. Small societies can maintain stability in the long terms by following notion of sustainable development. Smaller societies have a smaller demand for resources. As, lesser the number of individuals lesser will be the demand for resources and these resources will be available for future hence, smaller societies will maintain stability. Smaller societies can be governed by internal controls more effectively than larger societies because members can control the use of resources by creating awareness among themselves and use of resources can be checked upon. Small societies rely more heavily on legislation and military forces because these can ensure that all norms of resource conservation and sustainable development are strictly followed by members of the society.
Therefore, all options are useful for maintaining stability in the society.
