. Limb bones within unrelated animals that have the same basic structures are considereda. vestigial structures.
b. homologous structures.
c. embryological.
d. analogous structures.

Answers

When you have unrelated animals in biology which have limbs that have the same basic structure we consider these things to be homologus. As the first poster noted, an example is a wing of a bird or a hand of a human. When we're talking about analogous structures, we're talking about things which perform the same function yet don't have the same structure. 

DNA functions as a sort of recipe for the proteins that make an organism what it is and make it work. It doesn't make proteins directly but directs a series of steps that result in proteins. Which sequence below correctly follows how this works?

Answers

Answer:

This question lacks options but the sequence follows this pattern: DNA ---> RNA ----> Protein

Explanation:

DNA is the stored form of the genetic material in living cells. It contains the genetic information needed by an organism to function. However, this information needs to be decoded and expressed. The cell does this by employing two major processes: transcription and translation. Transcription is the process whereby the information in the DNA is used to synthesize a RNA molecule.

The RNA molecule is specifically called a messenger RNA (mRNA) which is formed by copying the information in the nucleotide sequence of the DNA into it using complementary base pairing. The next process after the mRNA has been synthesized is to use the mRNA as a template to direct the synthesis of amino acids, which are building blocks of proteins. The mRNA sequence is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid.

The sequence of the mRNA is read in the ribosome (organnelles of Protein synthesis). Each CODON read means the addition of one amino acid to the polypeptide chain. The order of the amino acid sequence determines the PROTEIN that is formed.

In a nutshell, the order of sequence in the DNA is used to synthesize a mRNA. The order of sequence in the mRNA is used to synthesize an amino acid sequence. The order of amino acid sequence determines the PROTEIN. Hence, DNA does not make proteins directly but is a recipe for its production.

Compare Organisms that do not have ventilation system to ones that have one

Answers

Organisms that have ventilation systems will draw in air (orwater) that is rich in oxygen and will draw out air that has carbon dioxide. Thisis essential for a multicellular organism to thrive because carbon dioxide isharmful for an organism since carbon dioxide (CO2) is a waste product. Such isthe system that contain veins, capillaries and arteries. On the other hand, organismsthat don’t have ventilation system, can survive without it because they aresingle-celled and the path for the nutrients and needed oxygen is so short thatthey can efficiently exchange gases at the surface.

Which of the following accurately describes a step within transcription?A. DNA polymerase uses one strand of RNA as a template to put together nucleotides.
B. The RNA strand is produced within the cytoplasm.
C. The DNA strand is used as a template for which a complementary RNA strand can be produced.
D. The RNA strand forms a template by which DNA can be built

Answers

The answer is C. The DNA strand is used as a template for which a complementary RNA strand can be produced. Transcription is a molecular process in which RNA is produced using DNA as a template. Namely, one strand of DNA is used as a template for which a complementary RNA strand is produced. This is the first step in gene expression.
C) The RNA strand can be produced.
