Answer:
Some serious diseases like anthrax is also caused in animals by the microbes. Microbes also cause diseases of plants like blights in potatoes, sugarcanes, oranges etc. They also reduce the yield. Microbes grow on food products and render them unfit for consumption.
Explanation:
Answer:
The atomic numbers of both are 54 while the mass numbers are 131 and 133 respectively.
Explanation:
- The number of protons = Atomic number. So, if the atom has 54 protons and it remained unchanged, then the two types of atoms of this element both have atomic numbers of 54.
- On the other hand, mass number is the sum of protons and neutrons
So, if type 1 has protons = 54 and neutrons = 77: mass number = 54 + 77 = 131
if Type 2 has protons = 54 and neutrons = 79: mass number = 54 + 77 = 133
(Since the possibility of atoms of the same element to have different mass numbers but the same atomic number is called isotopy). The two types of atoms with mass numbers 131 and 133 described are isotopes.
Answer:
Its B I just took the test and got a 100%
Explanation:
Heterogeneous Mixtures aren't uniform and are separated in the mixture. They are usually more easily able to be separated. An example is milk and cereal. The cereal isn't uniform because the milk and cereal still are separated and have their own identities. (You can easily just remove cereal from milk using a strainer)
Homogeneous Mixtures are uniform in composition and the multiple elements have become one solution. These mixtures are hard to separate into their components. An example is tap water because it contains water as well as various minerals that can only be separated by performing chemical reactions.
Answer:
The defect of vision suffered by the person is Myopia
Explanation:
The person can't see farther objects but is able to read a book which is placed closely to the eyes, using these observations the person is suffering from MYOPIA(nearsightedness) in which observer see close objects clearly but farther objects appear blurred.
The light entering the eye isn't correctly bent, the eyeball becomes big , or the eye lens become too converging, which converges the light ray in front of the cornea
This defect can be cured by using concave lenses.
