The type of inheritance displayed by the illustration is incomplete dominance.
Incomplete dominanceIt is a kind of inheritance in which one of the two alleles of a gene exerts incomplete influence on the other allele.
For example, a cross of white and red flower plants yielding a plant with pink flowers. It means that the dominance of the red or pink allele is incomplete.
The same is applicable to a blue fish mating with a yellow fish to produce green offspring. A blend of the two colors occurred.

How is desalination different from water reclamation? a. desalination is less expensive than water reclamation. b. desalination recharges aquifers. c. desalination provides water suitable for drinking. d. none of the above please select the best answer from the choices provided a b c d
Desalination is different from water reclamation because desalination provides water that is suitable for drinking. Hence, the correct option is C.
What is Desalination?
Desalination is the process of removing salts or other minerals and contaminants from seawater, brackish water, and wastewater effluent and it is an increasingly common solution to obtain fresh water for human consumption and domestic/industrial utilization.
Water reclamation is the process of converting municipal wastewater (sewage) or industrial wastewater into water that can be reused for a variety of purposes. Water reclamation is also known as wastewater reuse, water reuse, or water recycling.
On the other hand, Desalination is an expensive process. Desalination is an artificial process and would not add back to groundwater storage. Desalination provides water suitable for drinking.
Therefore, desalination is different from water reclamation because desalination provides water that is suitable for drinking. Hence, the correct option is C.

Type the correct answer in the box. Express your answer to three significant figures. Calcium nitrate reacts with sodium phosphate to form sodium nitrate and calcium phosphate. Given 96. 1 grams of calcium nitrate, what’s the theoretical yield of calcium phosphate? Use the periodic table and the polyatomic ion resource. The mass of calcium phosphate the reaction can produce is grams.
6.07 grams is the theoretical yield of calcium phosphate (Ca₃(PO₄)₂).
How we calculate mass from moles?Mass of any substance can be calculated by using moles as:
n = W/M, where
W = required mass
M= molar mass
Given chemical reaction is:
3Ca(NO₃)₂ + 2Na₃PO₄ → 6NaNO₃ + Ca₃(PO₄)₂
From the stoichiometry it is clear that:
3 moles of Ca(NO₃)₂ = produce 1 mole of Ca₃(PO₄)₂
Given mass of Ca(NO₃)₂ = 96.1g
Mole of Ca(NO₃)₂ = 96.1g/164g/mol = 0.5859moles
So, 0.5859 moles of Ca(NO₃)₂ = produce 0.5859×1/3 = 0.0196 moles of Ca₃(PO₄)₂
Required mass of Ca₃(PO₄)₂ will be calculated by using moles as:
W = 0.0196mole × 310g/mole = 6.07 grams
Hence, 6.07 grams is the theoretical yield of calcium phosphate.

A gas at a constant pressure occupies 2.24 L at 52 C. If the sample is cooled until it
takes up 1.66 Lwhat is the new temperature?
The new temperature of the gas is -32.15 °C or 240.85 K.
The new temperature of the gas can be calculated using the mathematical representation of Charles's law
Charles's lawCharles's law states that at constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature.
Formula:
V/T = V'/T'................ Equation 1Where:
V = Initial volume of the gasT = Initial temperature of the gasV' = Final Volume of the gasT' = Final temperature of the gas.Make T' The subject of the equation
T' = V'T/V............. Equation 2From the question,
Given:
V = 2.24 LV' = 1.66 LT = 52 °CWe need to convert the initial temperature T above from °C to Kelvin (K) by adding 273.
T = (273+52) = 325 KSubstitute these values into equation 2
T' = (1.66×325)/2.24T' = 539.5/2.24T' = 240.85 K.T' = -32.15 °C.Hence, The new temperature of the gas is -32.15 °C.

The change in enthalpy of the given reaction is 175.91 kJ/mol, which shows that reaction is exothermic.
How we calculate ΔH for the reaction?Change in enthalpy for the overall reaction will be calculated as:
ΔH = Enthalpy (H) of the product - Enthalpy (H) of the reactant
Given chemical reaction is:
NH₃(g) + HCl(g) → NH₄Cl
Heat of enthalpy of NH₃ = -46. 19 kJ/mol
Heat of enthalpy of HCl = -92. 30 kJ/mol
Heat of enthalpy of NH₄Cl = -314. 4 kJ/mol
Enthalpy of the reaction is calculated as:
ΔH = -314. 4 - [-46. 19 + (-92. 30)]
ΔH = -314. 4 - (-138.49)
ΔH = -175.91 kJ/mol

Answer:
Baseball: PE

Basketball: PE
Arrow: KE
Cliff Diver: PE
Swinging Girl: PE
Grasshopper: PE
Bobsled: KE
Slingshot: PE
Explanation:
For a thrown object, KE and PE are in a sort of equilibrium. As the object climbs towards its highest point, it slows down as the initial KE that initiated the movement runs out. At the highest point, it is out of kinetic energy and full of potential energy. Gravity then pulls on the object and causes it to accelerate, thus giving it more KE. The PE at the top of the arc is because at that point, the object has the potential to fall to earth. This is the reasoning behind the baseball, swinging girl, and grasshopper.
This is, in a way, the same reasoning behind the other potential energy cases as well. The basketball, cliff diver, and slingshot are all about to start moving. The first two will be pulled by gravity and the last one will be propelled be the stretchy slingshot material attempting to snap back into place.
All of the KE examples are due to the object or person actively moving towards or around something. This means that they have kinetic energy--the energy of movement!

A boat is at sea, where there are sea currents. The boat uses its engine against the currents and is stationary in the water. If the force generated by the boat to push it forward is 24,000 N, what can be said about the force applied by the current? It is zero.
A: It is zero
B: It is greater than 24,000 N.
C: It is less than 24,000 N and greater than zero.
D: It is exactly 24,000 N.
Answer:
D
Explanation:
according to newtons 3rd law action is accompanied by an equal reaction that is equal in magnitude but opposite in direction so magnitude of force should be same
If the force generated by the boat to push it forward is 24,000 N, force applied by the current is exactly 24,000 N. Therefore, the correct option is option D.
What is force?A force in physics is an effect that changes the velocity of a mass-moving object, causing it to accelerate from rest, for example. It is a vector quantity since it's capable of being a push or a pull and always has magnitude and direction. It is denoted by the letter F and is measured in newtons (N), the SI unit of force.
The net force that an object experiences is equivalent to the pace that its momentum varies over time, according to Newton's second law in its original formulation. This equation suggests that an object's acceleration seems inversely proportional to the total force that it experiences if the item's mass remains constant. If the force generated by the boat to push it forward is 24,000 N, force applied by the current is exactly 24,000 N.
Therefore, the correct option is option D.
