B and D? or the second and fourth ones
Explanation:
Answer:
In simplest terms, water makes up about 71% of the Earth's surface, while the other 29% consists of continents and islands.
Explanation:
The organelle described above is called the endoplasmic reticulum.
The rough portion of this called the granulated endoplasmic reticulum and the ribosomes attached to it enable it to produce proteins.
The smooth portion of this organelle does not contain ribosomes and it has a role in the synthesis of lipids.
The haploid number of the chromosomes should be 32.
Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc.
Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote.
Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.
