In a particular human family, John and his mother both have brachydactyly (a rare autosomal dominant allele causing short finger
Luba_88 [7]

Answer:

Brachydactyly and Huntington are phenotypic diseases that develop when a person has one or two dominant alleles for these traits.

John's father has the Huntington disease, but not brachydactyly so his genotype is Hh/bb.

John's mother is a healthy women with brachydactyly, so her's genotype is probably hh/BB or hh/Bb.

You want to test which size of soccer (football) ball is easiest to juggle with your feet. You test a size 3, size 4 and a size
Semenov [28]

Answer:

<u>independent variable:</u> size of soccer ball

<u>dependent variable</u>: period of time the balls stay in the air

<u>control variable</u>: parts of the body used to juggle the ball

Explanation:

The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.

The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.

The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.

Hence, in the illustration;

<u>independent variable</u>: size of soccer ball

<u>dependent variable</u>: period of time the balls stay in the air

<u>control variable</u>: parts of the body used to juggle the ball

Why does it make metabolic sense for the same hormone signal to stimulate glycogenolysis and inhibit glycolysis in the liver whi
Debora [2.8K]

This is because if the two  metabolic processes were to be  active at at the same time;  

Two molecules of<u> ATPs</u> and <u>Guanosine triphophate </u>(sometimes used for  energy transport) <u>will be expended per each cycle, with no  compensatory rate  of replacements present  at the moment in the cell,this  affects cell metabolism for energy availability</u>

<u>2</u> Both<u> Glycolysis and Gluconeogensis </u>are both<u> exergonic processes  in cells. </u> The  heat energy liberated from these Calorinogenic effects  will be higher than what the natural thermodynamic barrier of cells can withstand. Consequently;  the heat will raise temperature of the cells affecting metabolic activities of hormones and enzymes which are (proteins) ,and easily denature by high temperatures.    

However, in muscles cells,gluconeogeneis is a compensasory process of Glycolysis. This because during active exercise with high metabolic demand in muscles cells, glucose is rapidly metabolise  to to pyruvate,(but not at the rate that the Citric acid  cycle can  metabolise) for Lactic acid production by muscles cells for energy production.  Pyruvate must be broken down rapidly so that NAD+ will be available for  Glycolysis to continue. Therefore  to sustain Glycolysis at this rate  continuous supply of glucose is supplied  from Gluconeogenesis.
