Answer:
Protosomes
Explanation:
Protosome is a multicellular organism whose mouth grows before the anus from a primary embryonic opening which includesphyla mollusk, arthropod or annelid. Protosomes are developed by spiral cleavage during embryo development.
Protosome animals have bilateral symmetry and three germ layers. Some of the examples of protostomes are snails and slugs (mollusk), earthworms (annelids), and spiders, lobsters, barnacles (arthropods).
Hence, the correct answer is Protosomes .
A adaptation is a trait that helps an organism survive and reproduce.
⭐️The answer is⭐️
Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine (Figure 3).
Answer:
The glenoid cavity is where the d. humerus articulates with the scapula.
Explanation:
The scapula is the bone that contains the glenoid cavity. The glenoid cavity is a part of the shoulder. This cavity forms the glenohumeral joint along with the humerus. The Humerus is a long bone of the upper arm, and the scapula articulates with this bone to form a ball and socket joint at the shoulder. These are all bones forming the shoulder girdle and upper extremities.
