Answer:
Semi-conservative DNA replication:
The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.
Conservative model of DNA replication:
The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.
The semi-conservative mode of DNA replication is found in the living organism.
Answer:
Let the interbred alleles be represente dy the letters A and B for two genes. Gene A will exist in two alleles, that will icnlude A and g while Gene B exists in two alleles, B and r.
The uppercase alleles are dominant to the lowercase alleles. The interbred long-shaped squash is AABB (aabb) and the true-breeding disk-shaped is ggrr AABB.The F1 offspring are AaBb.
The outcome of interbred of the F1 plants and genotypes and phenotype sof F2 for:
1) the disk-shaped phenotype, an offspring must inherit at least one dominant allele from both genes.
1 ggrr+ 2 Agrr+ 2 ggrB+ 4 AgBr = 9 disk-shaped offspring
2) To get the round phenotype, an offspring must inherit at least one dominant allele for one of the two genes but must be homozygous recessive for only one of the two genes.
1 ggrr+ 1 ggBB+ 2 AArB+ 2 gABB = 6 round-shaped offspring
3) To get the long phenotype, an offspring must inherit all recessive alleles:
1 AABB= 1 long-shaped offspring
Hence, the phenotype and genotype of F2 is is 9 disk-shaped offspring and 1 ggrr+ 2 Agrr+ 2 ggrB+ 4 AgBr; 6 round-shaped offspring and 1 ggrr+ 1 ggBB+ 2 AArB+ 2 gABB; and 1 long-shaped offspring and 1 ggrr+ 1 ggBB+ 2 AArB+ 2 gABB respectively.
Answer: Solution 2 because the single substrate easily get transformed into products at the active site of any of the 100 enzymes.
Explanation:
Since Solution 1 has 1 enzyme to 100 substrate while Solution 2 has 100 enzyme to 1 substrate, catalysis of the single substrate to product will be greater in Solution 2 as the enzyme will compete to quickly transform the single substrate in its active site unlike solution 1 will 100 substrates taking more time.
Answer:
Producers get energy from the sun
Primary Consumers get energy from producers
Secondary Consumers get energy from Primary Consumers
Tertiary Consumers get energy from Secondary Consumers
