Sunscreens contain chemical ingredients in their compositions, such as avobenzone, oxybenzone, octocrylene, homosalate, octisalate and octinoxate, which have been linked to health problems such as hormonal disruptions, cancer, as well as liver and kidney changes.

<h3>What is oxybenzone, octocrylene, and homosalate bad for?</h3>

Oxybenzone, octocrylene, and homosalateto protect from UVA also penetrates deep into the skin. The penetration  into the human body can cause several problems in human health such as

  • allergic reactions
  • cell mutation
  • deregulation of hormonal processes,
  • etc.

With this information, we can conclude that Oxybenzone, octocrylene, and homosalateto is considered a hazardous eye irritant and, as an allergen, is also known to cause skin allergies.

Plant ingredients make up the bulk of a bear's diet – every so often as plenty as ninety consistent with cent. However, fish and meat are vital reassets of protein and fat, aleven though maximum non-coastal bears depend upon carrion (along with winter-killed animals

  1. The maximum usually eaten styles of flowers are fleshy roots, fruits, berries, grasses, and forbs. If bears are at the hunt, their prey can consist of fish (particularly salmon), rodents like floor squirrels, carrion, and hoofed animals like moose, elk, caribou, and deer.
  2. They are particularly exact at catching the younger of those hoofed species. Grizzly bears also can goal home animals like farm animals and sheep and reason economically vital losses for a few ranchers.

By the 1900s what type of evidence was being collected at crime scenes to help positively identify suspects by one particularly
guapka [62]

Answer:

By 1900, Fingerprint was the evidence which was collected at crime scenes to help positively identify suspects by one particularly unique trait.  No two people can have the same type of fingerprints. It is a unique characteristic which is even not common among identical twins. Therefore, was considered as an important evidence for identification of suspects and linking them with the scene of offence. In 1904, the city of St.Louis, Missouri used fingerprint evidence for the first time for criminal identification.

4. A polypeptide has the following amino acid sequence: Met-Ser-Pro-Arg-Leu-Glu-Gly In the mutant below, indicate the type of mu
MatroZZZ [7]

Answer:

4. c. Deletion/ frameshift mutation

5. a. Tyr Tyr Asp Ser Gly

6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.

Explanation:

4)

A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.

5)

The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly

6)

The wild type DNA sequence is:

5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'

The mutant i.e. mRNA with the added G will be

5' ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'  

This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.
