Ecological and ethological approaches to the study of behaviour. The natural history approach of Darwin and his predecessors gradually evolved into the twin sciences of animal ecology, the study of the interactions between an animal and its environment, and ethology, the biological study of animal behaviour.
Answer:
1/3 of black F2 progeny will be homozygous.
Explanation:
Here, BB = black coat color = true breeding dominant black strain
bb = white coat color = true breeding recessive white strain
When true breeding black and white guinea pigs are mated to give F1 progeny:
BB X bb = Bb ( all black guinea pigs )
When two of the F1 guinea pigs are mated to give F2 progeny:
Bb X Bb = BB, Bb, Bb, bb
F2 progeny has 3/4 progeny as black (BB and Bb) . Out of them 1/3 are homozygous and 2/3 are heterozygous.
Hence, 1/3 of black F2 progeny will be homozygous.
Answer:
Explanation:
In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.
mitochondria has two membrane,
It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.
The folds also enables a large surface area that makes chemical process to occur in an efficient way.
