Answer:
Option B, they negate each other
Explanation:
Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.
Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.
Option B
Answer: Haploid number
In normal humans, sex cells contain the diploid number of chromosomes
Explanation;
Human somatic cells or body cells are diploid such that they contain two sets of 23 chromosomes which gives a total of 23 chromosomes. Examples of somatic cells in the body that are diploid include, epithelial cells, somatic cells, liver cells, blood cells, nerve cells, etc.
However, mature sex cells are haploid, which means they have one set of 23 chromosomes which means they have 23 chromosomes. Sex cells are the results of meiosis type of cell division in which a diploid cell divides to form four daughter cells that are haploid.
Answer:
Aluminum
Explanation:
The density of Aluminum is 2.7 g/cm3
We know the volume and mass of the unknown metal, as density is mass/volume: 81g/30cm3 = 2.7 g/cm3 which is the density of Aluminum :)
Answer:
D
Explanation:
Carbon is expelled not used for producing sugars or any of that
