Answer:
The mass number is 56
Explanation:
You just add the number of protons and neutrons to find the mass number of a atom.
Answer: Option (a) is the correct answer.
Explanation:
It is known that weight is equal to mass times acceleration due to gravity.
Mathematically, Weight = mass × acceleration due to gravity
Since, it is given that weight is 34 N and it is known value of g is 9.8 m/s.
Therefore, calculate mass of the box as follows.
Weight = mass × acceleration due to gravity
34 N = mass × 9.8 m/s
mass = 3.47 kg
Hence, we can conclude that mass of the box is 3.47 kg.
Answer:
When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed.

If a species is said to be extinct, then that species is reduced to zero. There are none living in existence. The affects to other organisms of its extinction would depend on their value to the ecosystem. Regardless, extinction completely stops evolution of the species extinct.
Answer:
The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid.
Explanation:
what is a virus A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.
