<h2>Region between 2 and 3</h2>
Explanation:
Muscles consists of two protein filaments:a thick filament which is made up of protein myosin whereas a thin filament is made up of protein actin
- During contraction,thin filaments slide past the thick filament resulting in shortening of sarcomere
- Myosin thick filaments grab on to the actin filaments by forming cross bridges
- The thick filaments pull the thin filaments past them making the sarcomere shorter
- The region between points 2 and 3 includes the area of overlap between thin and thick filaments
Answer:
Explanation:
Vertebrates are members of the kingdom Animalia and the phylum Chordata ((Figure)). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development. The deuterostomes, whose name translates as “second mouth,” consist of two major phyla: Echinodermata and Chordata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
Deuterostome phylogeny. All chordates are deuterostomes possessing a notochord at some stage of their life
Answer:
Bill should classify the organism as a bird.
Explanation:
It would be right for Bill to classify the newly discovered organism as a bird. This is because the birds are a category of animals which have feathers as well as hollow bones. As for the flying criteria, not all birds belonging to this category can fly. For example, ostrich and kiwi cannot fly but yet still belong to the category of birds, Hence, this newly found organism can be classified into birds as it has feathers and hollow bones.
Because during summer they don't like to be around urban areas and housing, they are always in coniferous forests; You might see them close to your house but only if they are struggling when the food is scarce, they usually migrate from Canada to grounds to winter widely across central and Southeastern U.S. which includes Florida; but on summer they prefer to stay in deep and damp coniferous forests.
