Answer:
Question 1: A Chordate
Question 2: C Sea Anemones
Question 3: B Lobster
Question 4: A Arachnid
Explanation:
Chordates are all the animals that have vertebrates (backbones)
The phylum Cnidaria includes those that have cnidocytes which are specialized cells for capturing prey. This includes sea anemones, jellyfish, and coral.
Arthropods are those that have an exoskeleton, segmented body, and paired jointed appendages like lobsters and other crustaceans.

Answer:
B. Providing the building instructions for living things
Explanation:
The function of protein macromolecules is that they provide the building instructions for living organims.
- Protein macromolecules are essential for the growth and repair of damaged tissues in the body.
- Each unit is made of covalently bonded amino acids.
- They are derived from protein based meals such as a diary products, beans, etc.
- Most of the works in the cells requires proteins.
Proteins are also polypetides.
I believe in both groups , the sperm swim from antheridia to aronia. Both are tied to water by swimming sperm that require water to reach eggs. Neither of them has pollen, seeds, flowers, or fruits. Seedless vascular plants, however, have xylem and phloem, which bryophytes lack. For seedless vascular plants Cells in diploid sporophyte such as fern from undergo meiosis, releasing haploid spores that germinate and develop into gametophytes. Bryophytes reproduce sexually by forming sperm and egg cells within separate haploid male and female gametophytes.
