Olivia says global warming can't be real because a blizzard in her town last winter lasted four days. How would you explain to O

livia that her assumption is incorrect?
A.) Global warming melts polar ice, resulting in colder winters.

B.) Global warming causes air to be moister, resulting in more frequent blizzards.

C.) Global warming has mysterious effects, but we should trust scientists when they say it is happening.

D.) Global warming changes the elevations of some places, so places that were low elevation and rarely had blizzards are now high elevation where blizzards occur.

4 A reaction that needs water,<br> macromolecules are broken down<br> ( biochemistry )
LenKa [72]

Answer:

Hydrolysis

Explanation:

Hydrolysis is a reaction that needs water to breakdown macromolecules into simpler units.

Macromolecules are giant polymers made up of several repeating monomeric units.

  • These units are too complex for the body to digest and derive nutritional benefits from them.
  • During hydrolysis, the complex is broken down into monomers.
  • The monomeric units are absorbable and useful for the body.

Is it possible to have a knockout mutant plant that shows no visible phenotype that is different from the wild-type plant?
joja [24]

Answer:

Molecular genetic approaches to the study of plant metabolism can be traced back to the isolation of the first cDNA encoding a plant enzyme (Bedbrook et al., 1980), the use of the Agrobacterium Ti plasmid to introduce foreign DNA into plant cells (Hernalsteens et al., 1980) and the establishment of routine plant transformation systems (Bevan, 1984; Horsch et al., 1985). It became possible to express foreign genes in plants and potentially to overexpress plant genes using cDNAs linked to strong promoters, with the aim of modifying metabolism. However, the discovery of the antisense phenomenon of plant gene silencing (van der Krol et al., 1988; Smith et al., 1988), and subsequently co‐suppression (Napoli et al., 1990; van der Krol et al., 1990), provided the most powerful and widely‐used methods for investigating the roles of specific enzymes in metabolism and plant growth. The antisense or co‐supression of gene expression, collectively known as post‐transcriptional gene silencing (PTGS), has been particularly versatile and powerful in studies of plant metabolism. With such molecular tools in place, plant metabolism became accessible to investigation and manipulation through genetic modification and dramatic progress was made in subsequent years (Stitt and Sonnewald, 1995; Herbers and Sonnewald, 1996), particularly in studies of solanaceous species (Frommer and Sonnewald, 1995).

Increased numbers of CAG repeats in the exon of a gene is associated with certain diseases. In a specific gene, the existing CAG
Oksanka [162]

Answer:

The correct answer is - option b. to generate a protein with a run of consecutive glutamines.

Explanation:

The initiation code AUG is the code for methionine and as well as the initiation code for the particular protein or peptide chain. In this protein, there is a repeat of CAG is increased with the initiation code so, even though they are in zero reading frame they code for their amino acid which is glutamine.

So. an increased number of CAG repeats will result in a protein with the a run of consecutive glutamines.

How did the Mafia gain the interest and scrutiny of the public?
mihalych1998 [28]

Mafia gain the interest and scrutiny of the public through their unique and fearful actions.

Mafia gain the interest and scrutiny of the public by threatening people in the society as well as killing some of them. The main aim of Mafia is to earn money so they perform many actions in order to gain money from the public such as extortion, kidnapping etc.

The person who gives money to Mafia is safe but that person who refuses to pay money to Mafia will gain the punishment of death so we can say that in this way Mafia gain the interest of the public.
