Absolute Dating. The nuclear decay of radioactive isotopes is a process that behaves in a clock-like fashion and is thus a useful took for determining the absolute age of rocks. Radioactive decay is the process by which a "parent" isotope changes into a "Daughter" isotope.
Answer:
Explanation: It is a region of the earth that is extremely biological diverse and also
Under many threat due to habitat loss , clamate change or extensive species for guarding these region is important because host animals are there which is not found anywhere on earth
The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.
Explanation:
Given that:
Dominant trait is Y (yellow seed color)
recessive trait is y (green seeds color)
cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.
Punnet square shows that:
Y Y
y Yy Yy
y Yy Yy
All the plants produced will be tall phenotype.
The yellow seed plant plants will be heterozygous i.e Yy
the phenotype ratio is 4:0
The genotype ratio is 4:0
The genotype of the offspring is Yy
phenotype is yellow colored seed plant.
Answer:
Budding cells formed by the Saccharomyces are through "Cytokinensis"
Explanation:
Cytokinensis helps the budding cells of the Saccharomyces to get splitted over two new cells. These buds raise, throughout its cell cycle and afterwards leaves its mother cell while mitosis been completed. Budding of the yeast makes up an perfect model for the creature to study the meiosis. Diploid yeast can be prepared by making it undergo through meiosis in absence of nitrogen which will lead to the generation of an ascus along with 4 haploid cells. Due to this the property of the meiotic products can also be studied.
