Which reasons are the best for using only the fine-focus knob under high power? Select two. The diaphragm will not open wide eno

ugh by using the fine-focus knob. The stage or objectives move very little when the knob is turned. The objective will not move enough to risk breaking the glass slide. The coarse-focus knob will not turn when the microscope is set for high power

A recessive allele causes phenylketonuria (PKU) when homozygote. If the frequency of the recessive allele is 0.05 in the populat
Radda [10]

Answer:

0.095

Explanation:

Phenylkentonuria is a disease caused by a recessive allele.

The frequency of the recessive allele + the frequency of the dominant allele equals 1.

The frequency of the recessive allele is q = 0.05

The frequency of the dominant allele then is p = 1  - q = 0.95

If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .

2pq=2× 0.05 × 0.95

2pq=0.095

The heterozygote frequency in the population is 0.095

Does the genetic message get altered when the information is conveyed intracellularly under normal conditions? Support your answ
IRINA_888 [86]

Genetic transmission is the mechanism that drive evolution.Asexually reproducing organisms reproducing organisms reproduce using mitosis, while the sexually reproducing organisms reproduce using meiosis.

Both these mechanisms are involved in duplication of DNA which then get passed to offspring and RNA is key component in the duplication of DNA. The genetic information heritable biological information coded in the nucleotide sequence of DNA or RNA.

Genetic material is includes genes and DNA which control the development , maintenance and reproduction of organisms. These messages is passed from generation to generation through inherited units of chemical information. It consist of only two transcription and translation they known as gene expression , during this process of transcription store in gene DNA is passed to similar molecule called RNA in nucleus.
