Hi there! This question is a bit confusing.
Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge.
Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.
Your answer would be "Secondary cells are rechargable"
Have a great rest of your day!
Answer:
Diffusion is a passive process
Answer:
0.095
Explanation:
Phenylkentonuria is a disease caused by a recessive allele.
The frequency of the recessive allele + the frequency of the dominant allele equals 1.
The frequency of the recessive allele is q = 0.05
The frequency of the dominant allele then is p = 1 - q = 0.95
If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .
2pq=2× 0.05 × 0.95
2pq=0.095
The heterozygote frequency in the population is 0.095
The compost provides more nutrients for the seeds to feed on
