Answer: 3. The half- life of the isotope must be long enough to capture the age of the rock. and
4. their should be more than one unstable isotope.
In radioactive dating proces, the parent isotope is in unstable state which undergoes decay process to give stable daughter isotopes. Half-life is the amount of time it takes for half of the parent isotopes to decay. The rock dating requires a long lived parent isotope so that it can capture the exact rock age.
One rock when get decayed in the daughter isotope other will be available identify the age.
Answer:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b: Progeny ratio= 1: 1: 1: 1
c: 1/4
Explanation:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.
Gametes formed by female parent: All gametes with "bn" alleles.
c. The probability that the offspring will have a genotype of Bbnn=
Bb x bb= 1/2 Bb: 1/2 bb
Nn x nn= 1/2 Nn: 1/2 nn
Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.
A conversational plan with two habitat preserves, measuring a total of 20 square kilometers combined will preserve more species because this cause segregation of species based on their adaptability towards a safer and secure environment. For example if a lion and deer try to live in the same conservation area, then it’s obvious that the life of deer is always at risk. But in cases of segregated preserved areas both herbivorous and carnivorous animals can live separately. Also if there is special inclination of one species towards other then also these two species can live separately.
Segregation also enhances the diversity in the sense that it could lead to a new ecosystem with a new ecological balance within it. Conservation biologists focus on these areas as they claim that where the greatest number of unique species can be found and protected with in the large number of reserve areas with the least amount of effort
Not really sure about the human part but I know that most captive born predators die if they are released most likely because they have no wildlife instincts
