Decomposition of plant and animal matter present in soil is largely due to soil microorganism. True or False

Harman [31]

The question says,'decomposition of plants and animal matter present in the soil is largely due to soil micro organism. The statement is true. The soil microbes function by decomposing the organic matter in the soil to the forms usable to plants. The humus produce by these microbes is largely responsible for soil fertility.

How can organisms be so unique if the nucleotides making up dna are all the same between organisms?

sergejj [24]

Answer:

All organisms are made up of the four nucleotide bases of the DNA. Yet still all organisms are different from one another due to the sequence of the arrangement of these nucleotides. The pattern of arrangement of the nucleotides determines which organisms will be more similar and which will be more different from one another. The pattern of arrangement leads to the formation of genetic code which will differ in organisms. Hence, all organisms are made of the 4 nucleotides but differ due to the pattern of arrangement of the nucleotides.

Answer:

B. Populations of amphibians in a few local areas have declined dramatically in the last few decades

Explanation:

The continuous, low-level extinction of species that has occurred throughout the World and at least six species of frogs have not been seen for one to three decades and also it has recently been discovered that some species of salamander-specific chytrid has gone into extinction

A biologist at World University used Procedure IV to conduct an additional study and found the sequence following below. Using y

Nady [450]

Answer:

Valine-Leucine-Proline-Lysine-Histidine

Explanation:

The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.

N.B: Thymine is replaced by Uracil in the mRNA

For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU

Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)

Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).

GUG specifies Valine amino acid

CUG specifies Leucine amino acid

CCU specifies Proline amino acid

AAG specifies Lysine amino acid

CAU specifies Histidine amino acid
