How does one determine the number of protons, neutrons, electrons in an atom
KengaRu [80]

Remember that the number of electrons are equal to the number of protons, and to find the number of protons you have to look and see the atomic mass of the atom is equal to the number of protons, and to find the number of neutrons you have too subtract the atomic mass to the atomic number.

Example:

You want to find out how many protons, neutrons, and electrons are in Platinum:

  • Atomic number is equal to the number of protons:
  • 78 = 78
  • So platinum has 78 protons and electrons.
  • Subtract atomic mass to atomic number:
  • 195 - 78 = 117 (forgetting about the decimals)

So platinum has "78 protons, and electrons, and has 117 neutrons."

Hope this helps!

The article Bananas Under Attack claims that scientists need to research how banana genes might be manipulated by humans so that
Anastaziya [24]

Answer:

Explanation:

Gert Kema, a professor of tropical plant pathology at Wageningen University and a banana expert, led the study. "Black sigatoka has significant social, environmental and economic implications around the world. Thanks to the DNA sequencing of Pseudocercospora, we gain deeper insight into the interaction between the fungus and  banana plants. It can provide us with clues to increase the sustainability of banana cultivation and make it better for the environment, the locals, and the economy. For example, the findings show production and It provides us with the opportunity to develop  banana plants that are suitable for export and  resistant to black sigatoka. ”

This new understanding of the DNA of  black sigatoka also provides new information for more effective development. increase. And hopefully a crop protection product that is less harmful to the environment. This can reduce the amount of spray and improve the quality of life for those who work in  plantations and those who live nearby.

The substance that typically provides rigidity to fungal cell walls, and is also found in the external skeletons of insects and
enyata [817]

Answer:

Chitin

Explanation:

Chitin is a natural biopolymer that is made of the N-acetylglucosamine, modified glucose.

Chitin is an important polymer mainly for the fungi and the arthropod insects as it is present in the cell wall of the fungi and the exoskeleton of the insects.

The chitin provides a protective function to this organism that the digestive enzymes cannot degrade this chitin but only the symbiotic bacteria can digest eat therefore they are sometimes avoided to be eaten.

Thus, chitin is the correct answer.
