Answer:
Restoring force is a force which acts to bring a body to its equilibrium position. The restoring force is a function only of position of the mass or particle, and it is always directed back toward the equilibrium position. Therefore the restoring force of air particles should be displaced in the direction of the force and according to Newton 3rd law of motion, once the force is removed, restoring force of elasticity returns the displaced particle to a resting state .
Answer:
A. Lancelet
B. All chordates
Explanation:
A. Dorsal nerve chord is the only <u>unique feature</u> among all members of <u>phylum chordata</u> (mainly found in subphylum Vertebrata). In the given list, only lacelet is the Chordate whereas <u>snail belongs to phylum Mollusca</u>, <u>grasshopper belongs to Arthropda</u>, and <u>jellyfish belongs to Cnidaria</u>. Dorsal nerve cord runs along the length of organism's body.
B. <u>Gill slits</u> are <u>opening structures</u> to gills through which water passes from pharynx/throat to exterior. Their main purpose is to help filter the food particles available in surrounding water. Although they are typical for amphibians and fishes, chordates also possess gill slits at embryonic stages.
A change in the morphology of the leaves generated can frequently be used to detect when an apical meristem transition from the juvenile to the mature vegetative phase.
<h3><u>Apical meristem: What is it?</u></h3>
The growth zone within the tips of new shoots and leaves as well as the root tips of plants is known as the apical meristem. One of three meristem types, or tissues that can differentiate into distinct cell types, is the apical meristem. Plant growth takes place in the meristem tissue.
Apical growth is defined as taking place at the top and bottom of the plant. While lateral meristems are found between branches, intercalary meristems grow in girth like those of woody plants. The apical meristem is essential for expanding both the roots' and leaves' access to light energy and nutrients. For plants to succeed, they need to grow in both of these directions.
