Answer: a line connecting her mother and father, a colored circle representing Jenna, and two empty circles representing her sisters

Explanation: Jenna's red hair can be determined by incomplete dominance.

Incomplete dominance is a condition where neither of the alleles responsible for a trait is dominant.

In incomplete dominance, one allele for a specific trait is not completely expressed over its paired allele. So, if an organism is heterozygous for a trait, it shows a third phenotype.

From the point of view of energy use why is recycling better?
scoray [572]
When recycling we are reusing old stuff we get rid of and making it better like for example when you recycle plastic that plastic can turn into a toy for a kid or recycling an old rusty metal that can turn into a bed or a new table. Recycling is really good for the environment because you are changing something old into something new. 

Hope this helped :)

which molecules are produced in glycolysis and used in fermentation? a. acetyl-coa and nadh b. lactate, atp, and c. glucose, atp
tangare [24]

c. Glucose and ATP are produced in glycolysis and used in fermentation.

Glycolysis is the process of breaking down glucose to produce energy. It generates two pyruvate molecules, ATP, NADH, and water. The process occurs in a cell's cytoplasm and does not require oxygen. It can be found in aerobic and anaerobic organisms.

Glycolysis is a cytoplasmic pathway that converts glucose into two three-carbon compounds while producing energy. Phosphorylation traps glucose with the help of the enzyme hexokinase.

Fermentation is a metabolic process that involves the action of enzymes to produce chemical changes in organic substrates. It is narrowly defined in biochemistry as the extraction of energy from carbohydrates in the absence of oxygen. Fermentation is an ancient method of food preservation. The method is still used today to make wine, cheese, sauerkraut, yogurt, and kombucha.
