why scientists use the word dominant

Answers

Answer:

Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.

Answer:

Scientists use the word dominant for certain traits because they are more likely to show up. There are two different types of alleles for traits: dominant and recessive. Capital letters mean dominant and lowercase mean recessive. Scientists also use the word dominant for certain traits when certain traits stand out and are more prone to show up in offspring.

Which of the following properties of an unknown substance would allow it to be classified as a mixture? The unknown substance

Answers

Answer:

D. has different properties when sampled in different areas.

Explanation:

The general property of a mixture says that each substance or component in a mixture has its individual or different property which can be separated on the basis of different methods.

Such as a mixture of oil and water is a heterogeneous mixture and have different properties or different densities, which helps them to be sampled in different areas.

Hence, the correct answer is "D".

Can someone find the independent variable and the dependent variable ?

Answers

Independent Variable here is ”Speed”, since the independent variable is defined as (what's the scientist changes or what changes on its own)... And in here, both cars were traveling at 60 mph ’at a certain point, so, one of them might speed up or stay behind/lower it's speed from the other, depending on it's driver’.

Dependent Variable here is ”Distance”, since the dependant variable is defined as (what s being studied/measured).

What NaClNaCl concentration results when 259 mL259 mL of a 0.850 M0.850 M NaClNaCl solution is mixed with 567 mL567 mL of a 0.240 M0.240 M NaClNaCl solution?

Answers

Answer:

0.431M

Explanation:

To find the concentration of NaCl we need to know how many moles comes from each solution. Then, we need to sum the total volume in liters and, as molarity (Unit of concentration) is the ratio between moles and volume we can determine concentration.

Moles from first solution:

259mL = 0.259L * (0.850mol / L) = 0.22015 moles of NaCl

Moles from second solution:

567mL = 0.567L * (0.240mol / L) = 0.13608 moles of NaCl

Total moles:

0.22015 + 0.13608 = 0.35623 moles of NaCl

Total volume:

259mL + 567mL = 826mL = 0.826L

Thus, molarity of the mixture is:

0.3562 moles NaCl / 0.826

1. 1,010 L
2. 1,007.0 L
3. 1,007 L
4. 1,000 L

Answers

Answer:

The sum of given measurements is 1007 L.

Explanation:

The given measurements are 28 L, 42 L, 6 L, and 931 L.

We need to find the total of these measurements.

Total = 28 L + 42 L + 6 L + 931 L

It can be written as

Total = ( 28 +42+6+931)

One simplification we get Total = 1007 L

Explanation:

The statements which are true about volume are;

Measures the amount of space occupied by an object.

Equals the displacement of an object in water.

Discussion:

The volume of an object is a measure of the space it occupies. On this basis is the definition of matter as an object that occupies space.

Additionally, when an object is immersed in water; it's volume equals the volume occupied by the water displaced by it.

The ideas of Aristotle and Democritus were on a similar basis to the alchemists.

Explanation:

Aristotle believed that all matter was made from four elements: earth, air, fire, and water. Democritus was the first person to realize that if something was cut in half continuously it can never be broken down completely. Democritus called the units that could not be broken down atoms. Early alchemists believed and based their works on the notion that atoms could be rearranged into making new elements. All three of their ideas more or less work with atoms and elements.
