Base your answer on the pedigree chart below and on your knowledge of biology. The pedigree chart represents the inheritance of color blindness through three generations. Mary and Steve are expecting another child. What is the probability that the new baby will be colorblind

Answers

Answer 1

Answer:

1/2 or 50%

Explanation:

The probability would be 1/2 or 50%.

Color blindness is generally an X-linked recessive traits. Since males only have one X chromosome, they are either affected or not affected but females with two X chromosomes can be a carrier in addition to being affected or unaffected.

Also, males usually get their X chromosomes from their mothers while the two X chromosomes in females are contributed by each parents.

Let the allele for colour blindness be b.

Genotype of Steve would be [tex]X^bY[/tex]

Since, they produced a male child with color blindness, Mary is a carrier with the genotype: [tex]X^BX^b[/tex]

[tex]X^bY[/tex] x [tex]X^BX^b[/tex]

progeny: X^BX^b (carrier female), X^bX^b (affected female), X^BY (unaffected male), and X^bY (affected male)

Probability of producing color blind children = 2/4 = 1/2

Hence, the probability of their new born baby being color blind remains 1/2 or 50%

Coal contains carbon and other elements. Carbon dioxide forms when coal burns in the presence of oxygen. Which of these is the best evidence that a chemical reaction occurs when coal burns? Select one: A new substance is produced. Coal is made up of more than one element The shape of the coal changes. Oxygen is present.

Answers

Answer:

a new substance is produced

Explanation:

i just took my test and got this question right

The best evidence that a chemical reaction occurs when coal burns is a new substance is produced. The correct option is A.

What is coal?

Coal is a carbon containing fossil fuel, which is formed when the organic matter is decomposed inside the earth with heat and pressure by the earth crust. It is the most used fossil fuel.

Carbon dioxide is a gas produce when these fossils fuel burned. It is a green house gas and increase the warmth of the earth when produced. It is taken by plants to make their food.

When coal burns, it produces carbon dioxide which is a gas and coal is a solid, so here the chemical reaction is happening which is producing a new substance.

Thus, the correct option is A. A new substance is produced.

(a) The original value of the reaction quotient, Qc, for the reaction of H2(g) and I2(g) to form HI(g) (before any reactions take place and before equilibrium is established), was 5.56. On the following graph, plot the points representing the initial concentrations of all three gases. Label each point with the formula of the gas.

Answers

Answer:

Here's what I get

Explanation:

Assume the initial concentrations of H₂ and I₂ are 0.030 and 0.015 mol·L⁻¹, respectively.

We must calculate the initial concentration of HI.

1. We will need a chemical equation with concentrations, so let's gather all the information in one place.

H₂ + I₂ ⇌ 2HI

I/mol·L⁻¹: 0.30 0.15 x

2. Calculate the concentration of HI

[tex]Q_{\text{c}} = \dfrac{\text{[HI]}^{2}} {\text{[H$_{2}$][I$_{2}$]}} =\dfrac{x^{2}}{0.30 \times 0.15} = 5.56\\\\x^{2} = 0.30 \times 0.15 \times 5.56 = 0.250\\x = \sqrt{0.250} = \textbf{0.50 mol/L}\\\text{The initial concentration of HI is $\large \boxed{\textbf{0.50 mol/L}}$}[/tex]

3. Plot the initial points

The graph below shows the initial concentrations plotted on the vertical axis.

The initial concentration of the HI at the time 0 sec, has been 0.05 mol/L.

The balanced chemical equation for the reaction has been:

[tex]\rm H_2\;+\;I_2\;\rightarrow\;2\;HI[/tex]

The given initial concentration of hydrogen has been 0.030M, and the given concentration of iodine has been 0.015 M.

The reaction quotient for the following reaction has been:

Reaction quotient = [tex]\rm \dfrac{[HI]^2}{[H_2]\;[I_2]}[/tex]

The concentration of HI for the reaction quotient 5.56 has been:

5.56 = [tex]\rm \dfrac{[HI]^2}{[0.030]\;[0.015]}[/tex]

[tex]\rm [HI]^2[/tex] = 0.0025 M

HI = 0.05 mol/L or 0.05 M.

The concentration of the HI at the initial concentration has been 0.05 mol/L.

The graph attached has been plotted as the concentration as the function of time.

The initial concentration of hydrogen, iodine, and hydrogen iodide have been plotted as the function of time.

Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

Using sense organs to get information about the outside world and direct an appropriate body response

Answers

Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

Explanation: homoestasis is the process by which the body keep it's internal environment constant, regardless of change in the external environment. The human body has a normal range in which it's system operates and it uses homoestasis to keep these at constant.

Homeostasis could be positive or negative. It usually involves a sensor which detects the changes in the body and passes the information to the control center, a control center which receive information from the sensor and sends signals to the effectors and the effector which acts on the information sent by the control center to effect normalcy.

In this case, when a person eats food,he gets glucose. Blood sugar most be kept at constant so the endocrine system release the hormone insulin. Insulin helps to convert glucose to glycogen, which is the form it can be stored in the liver

When the blood sugar levels is low, the brain which is the control center causes glucagon to be released . This hormone converts glycogen to glucose

Answer:

Answer:Releasing insulin to decrease blood sugar and releasing glucagon to increase blood sugar

The pressure of a 70.0L sample of gas is 600 mm Hg at 20.0C. If the temperature drops to 15.0C and the volume expands to 90.0L, what will the pressure of the gas be?

Answers

Answer:

458.7 mmHg

Explanation:

Step 1:

Data obtained from the question. This includes:

Initial volume (V1) = 70L

Initial pressure (P1) = 600 mmHg

Initial temperature (T1) = 20°C

Final temperature (T2) = 15°C

Final volume (V2) = 90L

Final pressure (P2) =...?

Step 2:

Conversion of celsius temperature to Kelvin temperature.

This is illustrated below:

T(K) = T (°C) + 273

Initial temperature (T1) = 20°C

Initial temperature (T1) = 20°C + 273 = 293K

Final temperature (T2) = 15°C

Final temperature (T2) = 15°C + 273 = 288K

Step 3:

Determination of the new pressure of the gas.

The new pressure of the gas can be obtained by using the general gas equation as shown below:

P1V1/T1 = P2V2/T2

600 x 70/293 = P2 x 90/288

Cross multiply to express in linear form

P2 x 90 x 293 = 600 x 70 x 288

Divide both side by 90 x 293

P2 = (600 x 70 x 288) / (90 x 293)

P2 = 458.7 mmHg

Therefore, the new pressure of the gas is 458.7 mmHg

Grinding a seltzer tablet into powder increases the rate of reaction due to an increase of which factor?
Temperature
Surface area
Reactants
Concentration

Answers

Answer:

Surface area

Explanation:

The rate of a chemical reaction is increased when the surface area of a solid reactant is increased. This can be done by cutting the substance into small pieces, or by grinding it into a powder. If the surface area of a reactant is increased, it implies more particles are exposed to the other reactant.

When a seltzer tablet is ground into powder, the idea is to expose more of its surface to the other reactant. Since rate reaction depends on effective collision between reactants, more exposed particles implies a greater degree of collision between reactants and a faster rate of reaction.

Answer:

Salt bridge

Explanation:

Salt bridge is used in an electrolytic cell to transfer electrons from the anode to the cathode.

Salt bridge are used because they do not interfere with the constituents of the cell I.e the anode (+very electrode) and cathode(-ve electrode).

Examples of salt bridges are AgNO₃, KCl etc.

Salt bridge can be described as a tool used to link the oxidation half cell and reduction half cell in an electrolytic set-up or galvanic cell.
