Answer:
Different mass
Different volume
Same density
Explanation:
Intensive physical properties are those properties of a substance that is not dependent on amount i.e. do not change in response to changes in the amount of the substance. Intensive properties include density, temperature, boiling point etc.
On the other hand, extensive properties are those properties that are dependent on the amount of the substance. For example, mass and volume are extensive properties.
Hence, according to this question, measuring an entire bar of soap and comparing it to a piece of soap, the bar and the piece would have a:
- Different mass ( size dependent)
- Different volume (size dependent)
- Same density (size independent)
A culture medium consisting of agar, human blood, and beef heart is a
B) Complex medium
Answer:
2 chromosomes
Explanation:
The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.
Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.
The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.
Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.
This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.
Answer:
