Answer:

1. D.) Structural Data

2. C.) Overproduction

Explanation:

1. Structural Data was used to determine the similarities between the two species.

2. In biological terms, overproduction means that a generation had more offspring than can be supported by the environment. In this case, its a stronger hatchling beating out the waker hatchlings.

Pls help me !!!! Is for chemistry
Sphinxa [80]

Answer:

Explanation:

1) Molarity of the solution is (0.50/0.75)x1 = 0.66666 Mol/L

2) Molar mass of NaCl is 23+35 = 58g

Molarity = (0.5/58)/0.075 = 0.115 Mol/L

3) Molar mass of Li_{2}SO_{4} = 7x2 + 32 + 16x2 = 78g

Molarity = (734/78)/0.875 = 10.754 Mol/L

5) Molar mass of   Pb(C_{2}H_{3}O_{2})_{4}

= 207.2 + ((12x2) + (1x3) + (16x2))x4

= 207.2 + (24+3+32)x4 = 443.2g

Molarity = (0.0672/443.2)/0.1335 = 0.001135 Mol/L

6) Both are the same.

Solution 1 Molarity = 1.0/1.0 = 1 Mol/L

Solution 2 Molarity = 1.0/1.0 = 1 Mol/L

Molarities of the solutions are the same.

Which phrase describes conduction?
Akimi4 [234]

Answer:

Transfer of heat between two objects that are touching.

Explanation:

Conduction is the process by which heat is transferred from one object to another object that is touching and has different temperatures.

Eg: We can use a hot water pack to warm our back. Or While cooking we can feel the conduction process when heat process from the bottom of the pan to the top of the pan
