Answer:
The primary succession process can take hundreds of years to happen, even in medium amounts of rain and temperature.
Explanation:
The primary succession occurs when a community of plants begins to sprout in areas that have never been occupied by any type of living being. The primary succession occurs, for example, with the sprouting of vegetables in rocky outcrops. These plant species are known as primary species and although they are able to survive, these environments offer few resources for the development of living things. Generally, it takes hundreds and even thousands of years for primary succession to occur, even in environments with average temperature and precipitation.
Answer: 25% of the offsprings will be heterozygous for both traits
Explanation: A cross between BbFf and bbff will yield 16 offsprings with four different possible genotypes: BbFf, Bbff, bbFf, and bbff. Only BbFf is the genotype that is heterozygous for both traits, and there are four offsprings with BbFf genotype.
Therefore the percentage of the offsprings that are heterozygous for both traits is 4/16 x 100 = 25%
See the punnett square for the details of the dibybrid cross
Genetic alteration refers to altering DNA sequence. Gene alteration forms genetically modified products that modifies the gene sequence. DNA consist of two long chains of nucleotides that are twisted and joined together in hydrogen bonds. These DNA cannot be altered in nature but gene expression can be altered.
RFLP or Restriction Fragment Length Polymorphism exploits the variation of homologous DNA (Deoxyribonucleic Acid) sequences. This technique is frequently used in different types of analysis such as genotyping, paternity tests, forensics, hereditary disease diagnostics, and many others. In diagnosing diseases, PCR is use to find the DNA of pathogens in small amounts to diagnose hundreds of genetic diseases. While in forensic investigations, PCR can give a probably ID from 20 cells.
1.) [Bacteria] are single-celled organisms with no nucleus.
2.) The kingdom [Archaebacteria] is relatively small.
3.) Eubacteria are classified by [shape].
4.) [coccus] are round bacterial cells.
5.) [bacilli] are rod-shaped bacterial cells.
6.) [spirilli] are spiral-shaped bacterial cells.
