Answer:
The correct answer is - C. sqoop.
Explanation:
The Sqoop is tool created to changing or transfer in between a relational database and Hadoop HDFS servers. This tool import the data from the hadhoop to relational system and then export relational system to hadoop file system. It is command line interface application tool that helps in importing and exporting.
Thus, the correct answer is - option C
Answer:
The options
a) fraternal twins
b) identical twins
c) brothers and sisters
d) parents and children
The CORRECT ANSWER IS b)
b) identical twins
Explanation:
Identical twins both acquire identical genetic material. Therefore, if intelligence is basically controlled by heredity, you would foresee identical twins to possess the biggest correlation between IQ scores since they share 100 percent of the same genes
Answer:
(B) Energy transfer between trophic levels is almost always less than 20% efficient.
Explanation:
The ultimate source of energy on the Earth is the Sun. The energy coming from the Sun is captured by green plants by the photosynthesis. During photosynthesis sun energy is fixed into chemical energy (carbohydrate). So, in an ecosystem energy flow is unidirectional (from sun to the green plants). The fixed chemical energy from green plants is transferred to the herbivores then to carnivores through food. When one organism eats another organisms, only 10 % of the energy present in the organism is transferred as a food for the next organism and a large amount of energy is lost as heat into the environment. Thus, energy keeps on decreasing when stored energy moves from producers to top consumers. Thus, less than 20% energy transfer limits the trophic levels in most of the ecosystem.
Answer:
C
Explanation:
A)
DNA directs the synthesis of RNA.
B)
DNA splits into two strands of RNA.
C)
A strand of DNA is used as a template for the formation of RNA.
D)
Two strands of RNA are formed by copying each of the strands of DNA.
The correct answer would be that <u>a strand of DNA is used as a template for the formation of RNA.</u>
<em>Transcription is a process during which RNA is synthesized using DNA as a template. The coding strand of the DNA is utilized as a template for the formation of messenger RNA. During this process, the double helix structure of the DNA is unwound by an enzyme and the coding strand is bound by a short DNA strand at the beginning of a gene while another enzyme adds RNA nucleotide bases to elongate the short strand.</em>
The correct option is C.
Answer:
smooth endoplasmic reticulum
Explanation:
Smooth endoplasmic reticulum differs from the rough endoplasmic reticulum in not having ribosomes on its surface. The smooth endoplasmic reticulum (SER) extends from the rough ER and forms a network of membrane tubules. The function of the smooth ER is to serve as a site for the synthesis of lipids, fatty acids, and steroids such as estrogens and testosterone.
Enzymes for the synthesis of these diverse biomolecules are present in smooth ER. The smooth ER present in the muscle cells is called the sarcoplasmic reticulum. It stores the calcium ions which are released into the sarcoplasm of muscle cells during muscle contraction.
