Answer: mode of reproduction

Explanation: Phylum pteridophyte are vascular plants this means they are plants that possess xylem and phloem tissues. Phylum pteridophyte reproduce and disperse by spores. The dominant phase in pteridophyte is sporophyte.

Phylum bryophyte lack true roots and they are non-vascular plants (no xylem and phloem tissues). They reproduce via gamates, the dominant reproductive phase in bryophyte is gametophyte.

How do the sequence and composition of amino acids in a protein influence how a protein folds up
Fynjy0 [20]

Answer:

See the explanation below, please.

Explanation:

The amino acid sequence of a protein will determine the interactions inside and with the environment (that is, it will influence the conformations that are adopted at physiological temperature: the degrees of freedom). Example: the proline amino acid (Pro) has a cyclic structure, which implies a limitation in the random movement of the polypeptide chain.

In proteins, the primary structure determines the sequence of the amino acid sequence of the polypeptide chain (amount of amino acids present and their order by means of peptide bonds).

You decide to study two species of birds, both of which form monogamous pairs (one male and one female). In species 1, you find
TEA [102]

In two species of birds, both of which form monogamous pair(one male and one female), In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighboring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2. we would expect that female of species 2 would have sperm from multiple males in their reproductive tracts.

  • This is because the species 2 are having many eggs.
  • These eggs were formed due to fertilization with multiple male bird partners.
  • As a result we can expect eggs with different genotypes.

Thus from the above points we can conclude that two species of birds, both of which form monogamous pairs, female of species 2 would have sperm from multiple males in their reproductive tracts
