Answer:
The first clear recognition of enzymes came in 1833 when scientists discovered that an alcohol precipitate of malt extract contained a thermolabile substance that converted starch into sugar. They called the substance diastase. We now know that this was an enzyme that we call amylase.

Answer:
The theory of natural selection was proposed by Charles Darwin, which states the mechanism of biological evolution by explaining <u>adaptation and speciation.</u> There was five observation of the theory of natural selection.
1) The population produces more offspring than there are adults, in each generation.
2) The population does not continue to grow in size.
3) Food and many other resources are limited.
These three observations interfere that individuals compete for resources within a population.
4) Individuals within all populations vary.
5) Many variations are heritable.
He also assumed from these two observations that individuals inherit some characteristics that give a better chance of surviving and reproducing.
These observations and interpretations helped him to propose the theory of natural selection. The theory tells the <u>heritable characteristics in a population change over time</u> <u>become more adapted in generation after generations.</u>
Answer:
Out of, shrink
Explanation:
Water would move outside the cell due to osmosis. Osmosis is the movement of a solvent, water, in this case through a membrane from a region of high concetration to a region with less concentration .
The water molecules would move through the semi-pearmeable membrane from the region of high concentration (the bag) to a region with less concentration (the cup), thus, <u>equalizing the water concentration inside and outside the bag</u>. Since there is a higher concentration of salt outside, water will move out of the bag to equalize the concentration.
The result of this water movement would be an incurred bag or cell, hence, the cell would shrink.
Lazzaro Spallanzani's experiment is a good example of creativity, because he designed the experiment and found a new way to explore gastric juices. So...
Lazzaro Spallanzani, an Italian biologist and physicologist, was the first scientist to dissect animals for digestion trials.
He used the animals as models for humans digestive system, designed the experiment, and was the first to interpret the process of digestion.
I hope that helped ^_^
Explanation:
Bb x Bb
1BB, 2Bb, and 1 bb
Let B=black fur allele(dominant) and b=white fur allele(recessive),
¾ of the rabbit will be black while ¼ will be white.
Hence,
¾×100%=75%
¼×100%=25%
