Answer:
78
Explanation:
Chickens have 78 chromosomes. They inherit 39 from each parent, therefore a zygote (which is made up of an egg and a sperm, each a haploid gamete with 39 chromosomes) will have 78 chromosomes.
This is more than humans: we have 46 chromosomes, as we inherit 23 from each parent.
One parent cell and a genetically different cell Two genetically Which statement best describes development of disease-resistant crop plants.
Answer:
50 percent
Explanation:
The efficiency of ramp can be found by using this formula
(Output work/input work)*100.
Amounts of work to lift up = 600j
Amount of work bro take up to same height = 1200j
Efficiency of ramp = (600j/1200j) * 100
= 0.5 x100
= 50 percent
Therefore from the calculations above, the efficiency of this ramp is 50 percent
The type of solution that would cause a bacterium with a weak or damaged cell wall to burst as water moves into the cell is a hypotonic solution.
When a bacteria with a weak cell wall is kept in a hypotonic solution, the concentration of the water outside the cell is large, and within the cell it is low. This concentration gradient of water forces the water from the outside to exert force onto the cell wall. If the cell wall is weak, then the water rushes in bursting the cell.
I think it's the first and second option but I could be wrong because I don't know much about deserts :)
