Answer:
Option 1, Robotic arms used aboard the ISS are now used in delicate surgeries on Earth.
Explanation:
The robotic arm on the international space station is used in conducting surgery. The first space robotic arm was launched in 2001 and its name was “Canadarm 2”. Though the aim of this arm was to construct space station but now a days it is used in imaging the surgical work area and instruments through its camera. The best feature of this hand is that it follows the instruction with high efficiency and precision level.
Hence, option 1 is correct.
Tetraploidy will occur.
<h3><u>Explanation</u>:</h3>
The process of sexual reproduction is very necessary to maintain the genetic setup of the species over the races.
The normal chromosome content of a cell is called diploid state of cell. Its represented by the expression 2n. The cell division that takes place before the gamete formation is called meiosis. This cell division makes the chromosome number of the cells halved. So haploid cells are produced. Its represented by n.
Now as the gametes fuse, both the n becomes 2n and diploid state is regained.
But if the meiosis don't occur in the gametes, the gametes will remain 2n. So after fertilization, it becomes 4n. This state is called tetraploidy.
Answer:
Option A, B, C
Explanation:
The major advantages of multienzyme complex over a metabolic pathway is that it do not require individual pathway for each enzyme activation or inhibition. Instead it responds efficiently to the equilibrium changes of substrate supply and demand as compared to that of enzymes.
It tightly regulates the processes and is also faster than that of the metabolic pathway.
Hence, option A, B and C are correct
