Both the pellet (mitochondrial MDH) and the supernatant (cytoplasmic MDH) contain MDH.

Separation has been achieved. One does not need to separate each fraction to separate two cell fractions from each other.

Adding additional steps before and after the mitochondrial step will increase the purity, but based on the description to isolate the two enzymes, the job is done. Tell your partner to keep both fractions.

A compact, sterile dosage form with an ovoid or rod shape that is essentially pure steroid hormones compressed; it is designed for subcutaneous implantation in bodily tissues and acts as a depot for the hormone's prolonged, gradual release.

A man and woman have five children. what is the probability of this couple having four unaffected (either hbahba or hbahbs ) and
vlada-n [284]

The probability of the couple having four unaffected and one affected child if both parents are carriers will be A. 0.40.

<h3>How to calculate the probability?</h3>

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Unaffected = ¾; affected = ¼

The probability of this couple having four unaffected (either HbAHbA or HbAHbS ) and one affected = n!/a!b! (s^a) (t^b)

n= Total no. of progeny = 5

a = No. of unaffected = 4

b = No. of affected = 1

s = probability of unaffected = 3/4

t = probability of affected = 1/4

Therefore, the probability of the couple having four unaffected and one affected child if both parents are carriers will be:.

= 5! / 4!1! (3/4^4) (1/4^1)

= 120/24 (0.32) (0.25)

= 0.4 = 40%

Therefore, the probability is 0.4.

almond37 [142]

The properties of water that are at work to provide these protections are:

  • High heat capacity  
  • the high heat of vaporization

<h3>What is High heat capacity?</h3>

This refers to the situation where a substance can absorb a lot of heat before registering a change in temperature

Hence, we can see that The properties of water that are at work to provide these protections are:

  • High heat capacity  
  • the high heat of vaporization

This is because they regulate the temperature of the water that the fish experience and does not lose their habitat to evaporation
