Answer:
M.E = 5880 J
Explanation:
Given data:
Mass = 60 Kg
Height = 10 m
Mechanical energy = ?
Solution:
Formula:
M.E = K.F + P.E
K.E = 1/2 × mv²
P.E = mgh
Diver is not moving so K.E will be zero.
M.E = mgh
M.E = 60 kg × 9.8 m/s² × 10 m
M.E = 5880 J ( j= kg m²/s²)
The population of fish would slowly begin to die out as the deeper the water the less dissolved gasses there are.
Answer:
Explanation:
A cross between plants with round seeds (RR) and plants with wrinkled seeds (rr). If both parents are homozygous, having one type of gamete each, i.e. R from round seed parent and r from wrinkled seed parent (RR X rr).
R R
r Rr Rr
r Rr Rr
All the offspring of generation would be round with genetic constitution Rr. They will be heterozygous plants having two different alleles.
If both parents has heterozygous round seeds with genotype Rr. So, we have Rr × Rr. The gametes produced from each of the parents are of two types, R and r.
R r
R RR Rr
r Rr rr
The generation has a genotypic ratio of 1 RR : 2 Rr : 1 rr. The phenotypic ratio is 3 round : 1 wrinkled.
