Answer:

1/4

Explanation:

Incomplete dominance is when the dominant ("R") gene is not completely dominant and cannot fully mask or cover the recessive ("r") gene. This means that it will result in both genes expressing and a mix of traits appearing. In the case of a flower with "R" genes for red and "r" genes for white, the following possibly combinations exist:

RR = all red, no white "r" gene

Rr = pink, as both the "R" and "r" genes are expressed

rr = white, no red "R" gene

The Punnett Square shows that only one of the four phenotypes is RR and red.

Answer:

A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare? They both have the same mass. They are both denser than water.

Explanation:

nun

Answer:

Both the pebble and metal bead of the same mass will be equally accelerated  if they are at the same place, in this case, they are in the same place meaning they will be accelerated at the same speed towards the earth. Thus even if they are in the water they will sink at the same speed and finally will reach the bottom of the cup.

With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.

Answer:

Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease.

With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.

Explanation:

High cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries (atherosclerosis). These deposits (plaques) can reduce blood flow through your arteries, which can cause complications, such as:

Chest pain. If the arteries that supply your heart with blood (coronary arteries) are affected, you might have chest pain (angina) and other symptoms of coronary artery disease.

Heart attack. If plaques tear or rupture, a blood clot can form at the plaque-rupture site — blocking the flow of blood or breaking free and plugging an artery downstream. If blood flow to part of your heart stops, you'll have a heart attack.

Stroke. Similar to a heart attack, a stroke occurs when a blood clot blocks blood flow to part of your brain.

question 9.

Explanation:

Answer:

.0125 moles

Explanation:

Molarity = moles/volume

.05 M = moles/.250L

.0125 = moles

This is a combined gas law problem, according to which

[tex]\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}[/tex]

where P is the pressure of the gas, V is the volume of the gas, and T is the temperature of the gas, and the subscripts 1 and 2 correspond to the initial and final conditions of the gas. In this problem, we are given the initial pressure, volume, and temperature of the gas in the balloon:

P₁ = 1.0 atm

V₁ = 1.8 L

T₁ = 295.15 K (K = °C + 273.15).

Moreover, we are given the final pressure and temperature of the gas in the balloon.

P₂ = 0.86 atm

T₂ = 281.15 K.

What we want to find is the final volume, V₂, which we can obtain by rearranging the combined gas equation to solve for V₂:

[tex]V_2=\frac{P_1V_1T_2}{T_1P_2} = \frac{(1.0 \text{ atm})(1.8 \text{ L})(281.15 \text{ K})}{(295.15 \text{ K})(0.86 \text{ atm})} \\ V_2 = 1.99 \text{ L}[/tex]

This answer has three significant figures. However, the question as written would warrant an answer that comprises one significant figure (as 8 °C has only one sig fig). In that case, the answer would be 2 L. If the answer is to be given to two significant figures, the volume would then be 2.0 L.

Answer:

Molecules in the water move in a circular motion

Explanation:

Because of its circular motion it causes the waves to look like open circles which makes it easy for people to surf on

Water molecules move up and forward, down and back, in an overall circular motion in the wave. Therefore, option A is correct.

Circular motion is defined as the movement of an object while rotating in a circle. Circular motion can be uniform or asymmetric.

The angular rate of rotation and speed are constant in uniform circular motion, but the rate of rotation changes in non-uniform circular motion.

This means that circular motion can occur only if there is a "center seeking" force present; otherwise, things will travel in a straight line.

Within the wave, the water molecules move in a circular motion. Each water particle moves in a complete circle during a single wave period. The circle traced by a water particle on the ocean surface as a wave passes a given point has a diameter equal to the height of the wave.

Thus, option A is correct.

11.75 g H2O

Explanation:

3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3H2O + 3CO2

MM H2O = 18.02 g/mol

MM CaCO3 = 100 g/mol

? g H2O = mass CaCO3 x (1 mol CaCO3/MM CaCO3) x (3 moles H2O/3 moles CaCO3) x (MM H2O / 1 mol H2O) = (65.2/100) x 18.02 = 11.75 g H2O

Explanation:

Bohr model

Answer:

Why ? Because 1 molecule of H2SO4 gives 2 H+ ions per molecule while only one H+ ion is required to neutralize 1 molecule of KOH. So, 1 molecule of H2SO4 can neutralize 2 molecules of KOH. Hence, we would require 525 ml of 0.03 M H2SO4 to neutralize 525 ml of 0.06 M KOH. How will we prepare 525 ml of 0.03 M H2SO4 ?

Explanation:

Now, we have 0.025 M H2SO4 and we do not know how much volume we have.

We will use the standard N1 X V1 = N2 X V2 for this calculation.

N1=0.025 M; V1=unknown; N2=0.03 M and V2=525 ml.

So V1= (0.03 X 525)/(0.025) = 630 ml.

According to the molar concentration, 684 ml of 0.25 M H₂SO₄ can be prepared from 57 mL of a 3.0 M solution of H₂SO₄.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.In case  of 2 solutions,it is calculated as, M₁V₁=M₂V₂ substitution gives V₁=3×57/0.25=684 ml.

Thus, 684 ml of 0.25 M H₂SO₄ can be prepared from 57 mL of a 3.0 M solution of H₂SO₄.
