Examples of digestive enzymes are:
Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin, produced in the stomach.
Trypsin, produced in the pancreas.
Pancreatic lipase, produced in the pancreas.
Deoxyribonuclease and ribonuclease, produced in the pancreas.
One may also ask, what type of molecule are enzymes made from? proteins
One may also ask, what enzymes are found in the Oesophagus?
The esophagus produces no digestive enzymes but does produce mucous for lubrication. The acidic environment in the stomach stops the action of the amylase enzyme. , sucrases, and lactases, which are also present in the brush border of the small intestinal wall. Maltase breaks down maltose into glucose.
How is saliva produced in the mouth?
You make saliva when you chew. Sucking on a hard candy or cough drop helps you make saliva, too. The glands that make saliva are called salivary glands. The salivary glands sit inside each cheek, at the bottom of your mouth, and near your front teeth by the jaw bone.

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.

They then bring the bike inside to a room temperature environment for several hours to warm up and then check the pressure again.

The students wanted to test the air pressure in a plastic bottle of soda by comparing two bottles. They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.
D.
The students wanted to test the air presssure in a plastic bottle of soda by comparing two bottles. They put one in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the pressure of the bottle which was in the freezer had remained the same. The pressure of the gas in the bottle on the counter increased, causing it to push on the sides of the bottle making it harder to squeeze.

Explain how hormones recognize their target cells
Answer:
A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.
In a population of birds, brightly colored males and very dull males survive best. Which type of selection is this, and what is most likely true about the proportion of males of intermediate coloring?
Answer:
Stabilizing selection
Explanation:
Stabilizing selection may be defined as the type of a natural selection where the genetic diversity decreases and the population mean stabilizes on the particular value. It occurs to the individual trait when an extreme of the trait are selected against.
In birds, the bright color males attract more mates for survival but they also attract more predators. Over generation, the highest frequency color is for the intermediate coloring males.

If a specific kind of protein is not continually used by a cell, the gene for that protein is _________________________.
Answer: what are the answer choices?
Explanation:
Answer:
The gene for the protein is turned on and off at different times.
Explanation:
The turning on and off of the gene is described as gene regulation. This process is important because it enables the cells to react quickly to the changes in the environment.
Note that , this process mostly occur at transcription level during gene expression , and help in determining the amount of protein made by a gene.

In a density-dependent population, an increase in which of the following will most likely lead to an increase in population density?
Birthrate
Carrying capacity
Death rate
Emigration
Answer:
birthrate
Explanation:
In a density-dependent population, an increase in birthrate will most likely lead to an increase in population density. So, the correct option is A.
What is population density?Population density is the number of people in a given area of land. It primarily applies to people, yet occasionally it also does to other living things. That is a crucial geographic phrase. The amount of people who live in an area per square kilometer, or even other unit of land area, is referred to as population density.
We must divide the population's number by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area. Square miles or square kilometers should be used as the measure of land area. If we need to calculate the density of a relatively small place, then can use square feet or meters.
Therefore, the correct option is A.

20. Frigatebirds have webbed feet and spend much
of their life flying over the ocean but never land in
the water. What does this fact suggest about the
evolution of these physical and behavioral traits?
Answer:
Evolution changes the abilities of the Frigate birds.
Explanation:
The Frigate birds have webbed feet because they live in the ocean and unable to fly due to its big weight. Before the evolution, the Frigate birds lives in the ocean due to their large body weight but with the passage of time, evolution occurs that leads to formation of flying ability in the bird so now the bird have the old characteristics of their ancestor as well as new abilities in the physical traits of the Frigate birds due to the evolution.
