Which model can be used to trace genetic inheritance

1 answer:

5 0

To tract genetic inheritance ( phenotype or genotype) from one generation to another generation, PEDIGREE CHART is used. Pedigree Chart is a diagram shows the occurrence and appearance of a particular genes of an individual organism from its ancestor down to the generations it follows. Relationship in a pedigree is shown as a series of linear graph. Parents are connected to a horizontal lines while vertical lines will lead to the offspring.

What is the rate of a reaction if the value of kis 0.1, [A] is 1 M, and [B] is 2 M?

mel-nik [20]

Answer:

D. 0.4 (mol/L)/S

Explanation:

You simply have to plug in the given values into the rate law.

Rate = k[A][B]

Rate = (0.1)(1)²(2)²

Rate = (0.1)(1)²(4)²

Rate = 0.4

Acetic acid is a weak acid with a pKa of 4.76. What is the concentration of acetic acid in a buffer solution of 0.2M at pH 4.9.

masya89 [10]

Answer:

0.084 M

Explanation:

Using the Henderson-Hasselbalch equation for a buffer ( a buffer is solution contain a weak acid and it conjugate base; the solution resist change in pH)

pH = pKa + log ( base/acid)

4.9 - 4.76 =log ( base / acid)

10^0.14 = ( base / acid)

1.38 = (base / acid)

since there is 0.2 M in the buffer solution

the concentration of acid = $\frac{1}{(1+1.38)}$ × 0.2 = 0.084 M

When body temperature rises during physical activity, which thermoregulatory response is stimulated?

navik [9.2K]

Answer: Heat dissipation mechanism

Explanation: Heat dissipation mechanism is a thermoregulatory response in humans whereby the hypothalamus of the brain initiates certain processes to reduce the high body temperature. Eg, sweating is initiated which helps cool down the body temperature, also superficial arteries are dilated, thereby leading to flushing and decreasing heatloss into the air. And metabolic heat production is also reduced.

What is the mass of a sample of alcohol (specific heat = 2.4 J/gC), if it requires 4780 J of heat to raise the temperature by 5.

insens350 [35]

The mass of a sample of alcohol is found to be = m = 367 g

Hence, it is found out that by raising the temperature of the given product, the mass of alcohol would be 367 g.

Explanation:

The Energy of the sample given is q = 4780

We are required to find the mass of alcohol m = ?

Given that,

The specific heat given is represented by = c = 2.4 J/gC

The temperature given is ΔT = 5.43° C
