Answer:

when acid rain is inhaled, it can cause health problems and lung cancers. it's not good for our crops, it works as a poison for our crops when absorbed. acid rain affects our forests and lakes, because animals depend on the water from the rivers. acid rain may even kill the trees and plants that animals depend on for shelter, protections, and food.

Explanation:

it's pretty self-explanatory.

Answer:

The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

Proteins and nucleic acids both play vital roles in the structure and function of cells.
Eva8 [605]

Answer:

Part A: Proteins are made from amino acid monomers. There are 20 different types of amino acids which make up all the proteins of the body. The amino acids are made up of a carbon atom which is joined to an amino group, a carboxyl group and a variant group, known as R. Nucleic acids are made up of 5 carbon sugar, phosphate group and nitrogenous bases.  Hence, nucleic acids are made up of nucleotides.

Part B: Protiens are important molecule which carry out various functions of the body. They are involved in regulation of various body process. Some proteins are involved in the transportation of various molecules. Other type of proteins are involved in various immune functions and hence protect the body. For example, antibodies are proteins which defend the body against pathogens.

Nucleic acids are involved in the storing and expressing of genetic information. They also direct the body for protein synthesis.

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.

Identify the analogous structures
ra1l [238]

Answer: Here you go!

Explanation:

Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside
