Explanation:
A.moves from higher concentration to lower concentration
Answer: They use enzymes.
Explanation:
Cells employ enzymes to drive and speed up their chemical reactions without being used up themselves. They are the only macromolecular biological catalysts that can start a reaction using the smallest available heat energy, thus overcoming the issue of needing high activation energy. Enzymes work by converting specific substrates to required product by binding them to their active site.
Answer:
The probability that their first child will have long fingers is 20%
Explanation:
<u>Available data</u>:
- long fingers are inherited with 80% penetrance
- L represents the dominant allele for short fingers
- l represents the recessive allele for long fingers
Cross) Two people heterozygous for long fingers mate
Ll x Ll
Gametes) 1/2 L 1/2l 1/2L 1/2l
Punnet Square)

F1) 25% or 1/4 LL
50% or 1/2 Ll
25% or 1/4 ll
Long fingers are inherited with 80% penetrance, which means that 80% is the proportion of the population that expresses the phenotype long fingers. Hence, the probability that the first child in this cross will have long fingers is:
100% ------- 80%
25% -------- X = 20%
