Answer:
gametes are reproductive cells such as sperm and eggs. as gametes are produced the number of chromosomes must be reduced by half.
Explanation: why? the zygote must contain genetic information from mother and from father cells so the gametes must contain half of the chromosomes found in normal body cells.
Answer:
Specific heat capacity of metal is 2.6 J/g°C.
Explanation:
Heat lost by metal = Heat gained by water
ΔT = ΔT
where: is the mass of metal, is the specific heat capacity of metal, ΔT is the change in temperature of metal and is the mass of water, is the specific capacity of water and ΔT is the change in temperature of water.
32.8 x x (100.5 - 30.2) = 138.2 x 4.2 x (30.2 - 20.0)
32.8 x x 70.3 = 138.2 x 4.2 x 10.2
x 2305.84 = 5920.488
=
= 2.56761
= 2.6 J/g°C
The specific heat capacity of the metal is 2.6 J/g°C.
Answer:
a. Natural selection
Explanation:
The pesticide killed off all of the pest that weren't immune to it and the pests that were immune reproduced with each other creating offspring that were immune to it as well and so on this is a example of natural selection.
