Answer:
1. Meiosis 1.
2. Meiosis 2.
3. End.
4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.
B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
C. Meiosis.

Explanation:
Read the excerpt from The Riddle of the Rosetta Stone, by James Cross Giblin.
Another, more complete copy of the same decree that appeared on the Stone was found on a slab at Philae in 1848. Fuller translations of the hieroglyphic text soon followed. A Latin version came out in 1851, a French one in 1867, and an English one in 1871. But many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone.
Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone?
Answer:
many of the hieroglyphs on this slab were missing
Explanation:
The detail from the excerpt that develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone is "many of the hieroglyphs on this slab were missing."
From the available excerpt, it was written that despite many translations of the original text, including the fuller version, the French translation, the Latin version, and the English version, "many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone."
Answer:
Biodervasity.
Explanation:
The term refers to the variety of life on earth.It demonstrates the extent of variation at different levels of species,genetic and ecosystem in a community of organisms.
It not equal in its distribution on earth;but rather varies with the type of ecosystem available and the distribution of biotic and abiotic factors in the ecosystem. For example;
It is highest in the Tropics,due to the species richness and diversity of the region. However, it varies in other ecosystem based on species diversity peculiar to parts of the region .e.g it is highest in the marine ecosystem along the coast of abundant temperature for primary producers.
