Answer:
Addition used for 'either or' events , Multiplication used for 'and' events
Explanation:
Addition is used when Probability is of 'one event <u>or</u> other event'
Multiplication is used when Probability is of 'one event & other event'
Ex : Probability of A winning = 0.4
Probability of B winning = 0.3
Probability (A or B winning) = 0.4 + 0.3 = 0.7
Probability (A & B winning) = 0.4 x 0.3 = 0.12
Answer:
Humans release carbon dioxide (CO2) into the atmosphere through cellular respiration. This CO2 is used by plants during photosynthesis. During photosynthesis, plants release oxygen (O2) into the atmosphere. The oxygen is used by animals in order to carry out cellular respiration.
Explanation:
I put all I know into that so it should be right but if it isn't then I'm sorry
Answer:
The organism will pass on the traits to their offspring. If the offspring also has an increased chance of survival it will have a higher chance of passing on the traits. Over a long period of time the entire population can inherit this trait.
Explanation:
According to the theory of natural selection organisms with beneficial traits are more likely to survive to the reproductive stage and pass on the beneficial gene to their offspring. <em>Natural selection selects beneficial traits.</em>
Carbon dioxide is the compound in photosynthesis, I'm pretty sure
Answer:
The correct answer would be - 50%.
Explanation:
Hemophilia is a sex-linked recessive disorder that takes place in males more than in females as females have two X chromosomes so if one is affected other still able to make clotting factors but in males, there are only one x chromosome.
If a hemophilic man XhY marries with a carrier women XHXh then the chances of their son for normal blooding would be :
Gametes:
Male: Xh and Y
Female: XH and Xh
Then cross:
Xh Y
XH XHXh XHY
(carrier daughter) (normal son)
Xh XhXh XhY
(hemophilic daughter) (hemophilic son)
Thus, the chances of normal son is 50% among sons
