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.

1.- Prophase

2.- Metaphase

3.- A

4.- centrosomes

5.- Interphase

6.- D, A, C, F, E, B

7.- Animal cells, because plant cells have a cell wall that is a rigid structure that can be divided but gives support to the plant cell and in this picture, the cells do not this structure.

8.- Interphase

What can you determine about mechanical energy from this graph?​
Pachacha [2.7K]

Answer:

What can be determined from the graph includes;

a) The Mechanical Energy M.E. = 1.0

b) The initial K.E. =  1.0, The initial P.E. = 0

c) The period for the kinetic energy = The period for the potential energy = 0.25

d) The frequency of oscillation of the kinetic and potential energy = 4 Hz

e) The object starts with its maximum velocity

Explanation:

The equation between kinetic energy, K.E., potential energy, P.E. and total mechanical energy, M.E. is given as follows;

M.E. = K.E. + P.E. = Constant

From the graph, we  have;

a) M.E. = K.E. + P.E. = 1.0

b) At time t = 0,

The initial K.E. = M.E. = 1.0, P.E. = 0

At time t = 0.125,

P.E. = M.E. = 1.0, K.E. = 0

c) The period for the kinetic energy, K.E. = The period for the potential energy, P.E. = 0.25

d) The frequency of oscillation of K.E. and P.E. = 1/T = 1/0.25 = 4 Hz

e) The object starts in motion with maximum velocity at time t = 0.

Rickets in a condition in which the bones are soft. Children with rickets develop deformed bones. A lack of vitamin D, calcium,
cupoosta [38]

Individuals that will have the rickets condition are individuals that possess this dominant allele on the X chromosome.

<h3 /><h3>What is rickets?</h3>

The condition known as rickets causes the bone of children to be soft and flaky. It stems from insufficiency in vitamin D, calcium, and phosphorous. Scientific studies have shown that the deficiency is caused by a dominant allele on the X chromosome.

Even though the question is incomplete, we know that the individuals that will have the rickets condition are individuals that possess this dominant allele on the X chromosome.
