Vlad [161]

Answer:

  1. <u>The hours are the independent variable.</u>
  2. <u>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .</u>
  3. <u>The domain is 0 to 30 </u>
  4. <u>The range is 0 to 330 </u>

Explanation:

<em>The hours are the independent variable and  should be plotted on the x-axis .</em>

<em>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked )  and should be plotted on the y-axis </em>

<em>--------------- </em>

<em>Let +W+ = wages/wk earned </em>

<em></em>

<em>Let +h+ = hours/wk worked </em>

<em>The equation is: </em>

<em>+W+=+11h+ </em>

<em>The domain is 0 to 30 </em>

<em>( no hrs worked to 30 hrs worked ) </em>

<em>The range is 0 to 330 </em>

<em>( no wages eared to +11%2A30+=+330+ earned )</em>

13. Dihybrid Cross
Ksju [112]

Answer:

There is 56 percent chance that the offspring will be red and tall

Explanation:

A punnet square can be described as a diagram which is used to check the outcomes of a cross.  A monohybrid cross is a cross in which a single trait is studied. A dihybrid cross is a cross in which two traits are studied and the results of an offspring having two traits are predicted.

As we see, red is dominant over white and tall is dominant over short, the results of the punnet square show that there is a 56% chance for red and tall offsprings.

9 divided by 16 and multiplied by 100 gives 56.2.

You have a large bottle of 2% saline solution in the lab (2% NaCl, which is sodium chloride). You need 5 ml of 0.1% saline for a
zvonat [6]

Answer:

volume of 2% saline (V₁) = 0.25ml

volume of water = 4.75ml

Explanation:

The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:

C₁V₁ = C₂V₂

where:

C₁ = initial concentration = 2%

V₁ = initial volume = ?

C₂ = final concentration = 0.1%

V₂ = final volume = 5ml

C₁V₁ = C₂V₂

calculating for V₁

∴ V₁ = (C₂V₂) ÷ C₁

= (0.1% × 5) ÷ 2%

V₁ = 0.25ml

Now, let us calculate the volume of water needed:

V₁ + Volume of water = V₂ (volume of 0.1% NaCl)

0.25 + volume of water = 5

volume of water = 5 - 0.25

volume of water = 4.75ml

Trace the flow of energy through a typical food chain (describing "what eats what"), including the original source of that energ
tester [92]

Answer:

The answer is given below:

Explanation:

A food chain consists of producers and different consumers. Producers are the organisms which produces food using sun energy. Consumes directly eats plants or eat other animals to fulfill their energy needs. So, in any ecosystem energy flows through food chain in unidirectionl manner.

Sun is the ultimate source of energy. The producers uses solar energy to make chemical energy (glucose) through photosyntheis. The cosumers use this chemical enegy through food by eating plants. Some animals eat other animals to get energy. The chemical energy stored as ATP (an energy currency).

gregori [183]

Answer: Increased reproductive success of individuals with the ability to survive in a variety of water temperatures

Explanation: Natural selection establishes that the conditions of an environment favor or hinder (select) the reproduction of organisms according to their characteristics. Natural selection was proposed by Darwin as a means to explain biological evolution.

The trait subject to selection must be inheritable.

There must be variability of the trait among the individuals of a population.

The variability of the trait must give rise to differences in the survival or success of the player, making certain characteristics of the new appearance can be extended in the population.

The accumulation of these changes over generations would produce all evolutionary phenomena.
