researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a gametophyte generation, but lacks seeds. How should the researcher classify the plant?
pteridophyte
Explanation:As you might guess, Pteridophyte are plants that can move through the air. They do not make new plants by releasing seeds.
Other pteridophyte characteristics include the following:
They exhibit alternation of generations, in which the sporophyte and gametophyte generations are observed.Sporophytes are plants with true roots, stems, and leaves.Sporangia grow in clusters on sporophylls.I hope this helps you

how is dna copied in your own words?
Answer:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
Answer:
website answer... the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
Explanation:
in my own words... the double helix and the separation of dna strands and the priming temlete strand and the assembly of a brand new dna segment

Which mrna sequences would form a structure that is a cue for transcription termination of some genes?
Answer:
First, you must know what the stop codons are: UAA, UAG, and UGA
Whenever this sequence is read, it signals for an end in transcription and amino acids will stop being formed
Thus, 5′−GGCCCUUUUAGGGCCUUUUU−3′ contains a cue for transcription termination as it will stop after the codon "UAG"
Explanation:
Those mRNA sequences that consist of the stop codons like UAA, UGA, and UAG would form a structure that is a cue for transcription termination of some genes.
What do you mean by Transcription?Transcription may be defined as the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Stop codons are responsible for the termination of transcription of almost all the genes. They are necessary for inhibiting the excessive expression of some genes.
Therefore, those mRNA sequences that consist of the stop codons like UAA, UGA, and UAG would form a structure that is a cue for transcription termination of some genes.

Which statement presents a credible and unbiased argument for selecting a particular livestock animal as a human organ donor?
(Please help, this is a practice question btw)
A. A calf is the best candidate, because a cow's gestation period most closely matches a human's (9 months/280 days), and that feels most natural.
B. A lamb is the best candidate, because sheep are less likely to be sold as a meat source and because lambs are inherently cute.
C. A piglet is the best candidate. A pig's gestation period is the briefest, so human hearts could be more quickly grown and transplanted.
D. Livestock candidates should be chosen based on the patient's preference, otherwise there could be organ rejection.
Livestock candidates should be chosen based on the patient's preference as there could be organ rejection is an unbiased argument.
What is an Unbiased argument?This type of argument shows the reader both sides and bids the reader decide.

How does a comparison of bone structures of two animal provide evidence of an evolutionary relationship
Answer: Comparative Anatomy
Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

how are organisms separated
Answer:
prezgotic and postzygotic barriers
Explanation:
according to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by PREZGOTIC AND POSTZGOTIC BARRIERS, which prevent mating or the production of biable, fertile offspring.Answer:
Organisms separate using a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division. Generally, mitosis is immediately followed by the equal division of the cell nuclei and other cell contents into two daughter cells.
