Minerals in a rock becoming powdery and rusty is a chemical reaction, thus is Chemical Weathering.
Answer:
a. Liver cell
Explanation:
Meiosis is a reductional division that produces haploid cells from diploid existing cells. Male and female gametes such as sperms and egg cells are haploid. Sperms are produced by meiosis in spermatogonia. The egg cell is produced by meiosis in oogonium. The liver cell is a diploid cell and is produced by mitosis. Mitosis maintains the DNA content and genetic information of the parent cells into the daughter cells.
An individual’s behavior characteristics, emotional expression, and intensity that is established from birth is known as temperament.
Answer:
250 nm
Explanation:
Data provided in the question:
Length of the bacteria cell = 2.5 micrometers (µm)
Now,
We know that,
1 m = 10⁶ µm
or
1 µm = 10⁻⁶ m
also,
1 m = 10⁹ nm
or
10⁻⁹ m = 1 nm
Therefore according to the above results we get,
2.5 micrometers (µm) = 2.5 × 10⁻⁶ m
and,
2.5 × 10⁻⁶ m = ( 2.5 × 10⁻⁶ ) × 10⁹ nm
= 2.5 × 10³
= 250 nm
