What is the weather like at a front boundary?
lukranit [14]

Answer:

Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.

What are the 3 types of substitution mutations?.
loris [4]

Base substitutions, deletions, and insertions are the three different forms of DNA mutations.

A mutation is a long-lasting alteration to the DNA's nucleotide sequence that can occur during replication and/or recombination. Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.

Different Mutations

Base substitutions, deletions, and insertions are the three different forms of DNA mutations.

1. Base Replacements

Point mutations are single nucleotide replacements; you may recall the point mutation Glu ——-> Val is the culprit of sickle cell anemia. There are two types of point mutations, the most prevalent of which are.

A population has 1000 individuals. A PCR analysis of the genotypes of a gene associated with Lactase persistence are: LL = 450 L
ss7ja [257]

Answer:

L allele: 0.575 (or 57.5%)

l allele: 0.425 (or 42.5 %)

Explanation:

Homo-zygous individuals have two copies of the same allele (i.e., either L alelle or l allele), while heterozygous individuals carry both alleles at a time (i.e., one L allele and one l allele). In consequence:

- Frequency of the L allele: [(450 x 2) + 250] / 2000 = 0.575

- Frequency of the l allele: [(300 x 2) + 250] / 2000 = 0.425

Pode esterilizar plásticos na estufa?<br> Pode esterilizar vidros na autoclave?
maria [59]
No coloque ningún plástico en el horno, incluidas las cestas o bandejas de plástico para sostener la cristalería. Las esporas de las bacterias son muy resistentes al calor y no se eliminan por ebullición a presión atmosférica. En el aula, se puede usar una enlatadora a presión para esterilizar líquidos.
