Answer: Enzymes lower the activation energy found in food molecules
Explanation:
Food substances like yam, potatoes, egg etc are all made of chemical elements bounded to one another by chemical bonds such as hydrogen bonds, covalent bonds etc
During digestion, these bonds must be broken for carbohydrates to yield glucose, protein to yield amino acids.
Hence, added enzymes lowers the strength of this bonds i.e activation energy, by placing them into their active sites, which is equipped to cleave specific bonds
Thus, digestive reactions are quicker in the presence of enzymes than otherwise.
Answer:
provide flexibility
Explanation:
According to my research on studies conducted by various medical professionals, I can say that based on the information provided within the question the role of elastic fibers is to provide flexibility. Elastic fibers contain elastin, a protein that acts like rubber and allows them to stretch and recoil like rubber bands, making them very flexible.

Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.

The hormones that stimulate the breakdown of liver glycogen are epinephrine and glucagon. Epinephrine is the one that triggers the glycogen breakdown inside the muscle and also inside the liver. However, the liver is the one that is more active or responsive to the hormone called glucagon than the muscles. A glucagon is a hormone which is a polypeptide hidden by the cells of our pancreas called α cells whenever our blood-sugar is low. This hormone indicates the state of starving.
