Answer:
50% long black hair and 50% short hair
Explanation:
Attatched is a screenshot of a punnett square that shows the possibilities of the offspring having long or short hair. In short, the genetics of long black hair only need one big "L", while the genetics of short hair need to have 2 short "l"s. So when we draw the punnett square and combine the genetics, we get 50% have Llbb, and 50% have llbb
Answer:
Explanation:
When enzyme does not work properly it is said to be inactive and this affect its efficiency.
Substrate concentration - Enzyme requires adequate substrate concentration to be effective, when the concentration is high the enzyme activity increases and when it is low it decreases.
Temperature - Enzymes are more active at specific temperature at very high temperature enzyme can be denatured leading to a loss of its activity. Hence, enzyme should be made to work at its optimum.
pH- Enzymes are active at specific pH, when the pH is altered enzymatic activity may be reduced or enzyme become inactive. Hence, pH of enzymes should be maitained.
Answer:
41 minutes
Explanation:
According to this question;
- Roberto spent 90 minutes doing homework
- Roberto spent 2/3 hour reading. Since 1 hour = 60 minutes
2/3 hour = 2/3 × 60 = 40 minutes.
- Roberto spent 540 seconds making his lunch for the next day. Since, 60 seconds = 1 minute
540 seconds = 540/60
= 9 minutes.
The total amount of time Roberto spent reading and making his lunch is = 40 + 9 = 49 minutes.
Therefore, the amount of time Roberto spent doing his homework than reading and making his lunch is (90 - 49) = 41 minutes.
The first stage of cellular respiration is glycolysis. It does not require oxygen. During glycolysis, one glucose molecule is split into two pyruvate molecules, using 2 ATP while producing 4 ATP and 2 NADH molecules.
Answer:
Dopamine is a substance produced in the brain and is responsible for controlling our movements. The cells that produce dopamine are located in an area known as the brainstem, from where dopamine is then secreted into the basal ganglia, an area of the brain that plays an important function in regulating our movements.
