A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny.

In this set of examples the answer is:

D) The lamprey does not have a vertical column

Lampreys have a notochord that remains throughout life, but they have primitive vertebrae made of cartilage. Lampreys have vertebral arches, but nothing resembling the vertebral bodies found in all higher vertebrates. Even the arches are discontinuous, consisting of separate pieces of arch-shaped cartilage around the spinal cord in most parts of the body, changing to long strips of cartilage above and below in the tail region.

Stells [14]

The two main types of plants are vascular and nonvascular. Vascular plants are also knonwn as tracheophyte. They have vascular tissues -- xylem and phloem. Plants that are seed-bearing are vascular plants. On the other hand, nonvascular plants, or also known as bryophytes, are small, simple plants without a vascular system.

Describe how protein is synthesized from a strand of DNA to a polypeptide chain Please included the following terms in your resp

____ [38]

Answer:

Protein synthesis consists of a series of steps ranging from the transcription of DNA to messenger RNA (mRNA), to the coupling of this to transfer RNA (tRNA) and ribosomes to produce polypeptide chains by the addition of amino acids.

Explanation:

DNA is a molecule present in the nucleus of the cell, formed by a double complementary strand that is linked by specific sequences of nitrogenous base pairs. This sequential order contains the organized genetic information of a species.

The first step in protein synthesis occurs in the nucleus, through the transcription of DNA into mRNA, in which a single strand of mRNA is formed from the sequence of nitrogenous bases, with the help of the enzyme RNA polymerase. This transcription also includes the synthesis of tRNA and ribosomal RNA. Transcription occurs in the 5' → 3' direction of the DNA strand.
Once the different RNA molecules have been synthesized, the next step occurs in the cell's cytoplasm, with the binding of the mRNA to the minor subunit of the ribosome. In the sequence of nitrogenous bases in mRNA, a triplet of bases is called a codon -the base of the genetic code- each of which will encode a specific amino acid.
To the complex formed by mRNA and minor subunit of the ribosome a tRNA is coupled, which contains the anticodon that determines this coupling, in addition to the amino acid it encodes. This is the moment when the major subunit of the ribosome is attached and protein synthesis begins.

Each of the amino acids will be linked to others by peptide bonds -following the sequence of codons in the RNA- until synthesis stops with the appearance of the stop codons.
