Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

How do environmental factors and heredity affect personal health?
Thanks
Answer:
Heredity: all the traits and properties that are passed along biologically from both parents to child. To some degree this determines your general level of health. You inherit physical traits such as the color of your hair and eyes, shape of your nose and ears, as well as your body type and size.

A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow. The question can be Is flower color polygenic?
What is True breeding plant?A true breeding is a kind of breeding wherein the parents would produce offspring that would carry the same phenotype. This means that the parents are homozygous for every trait.
An example of true breeding is that of the Aberdeen Angus cattle. The cattle have been black for many generations, which is an indication that such trait passed on from many generations remains pure.
With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue flowers will produce only seeds that will grow into plants that have blue flowers.
Therefore, A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding red flower of the same species. All of the F, offspring are yellow. The question can be Is flower color polygenic?

When boiling water in a kettle, the top may move slightly if it is not tight. What evidence explains why this happens?
Answer:
Usually, the hottest is at the bottom, if the kettle is on top of a heating ... Also, there's a factor that's not so important for kettles, but otherwise can be ... When a phase change (like liquid to gas) occurs, it normally begins at a location that ... a slight disturbance (like putting in a spoon or some sugar, or moving it ..
Explanation:
Answer:
Since the water is boiling, and a lid is on there is a major amount of thermal energy just waiting to go somewhere, not to mention it takes the form of steam which much escape somehow, likely causing a very faint movement on the top of the kettle.

5. If the weather in Richmond, Virginia, changed to very cold (snow on the ground 8 months of each year) over the next few years, what change might occur?
a. The cold weather would cause a mutation in squirrels which causes their fur to be white.
b. If a mutation occurred which caused white fur to develop, such white squirrels would have a better chance to survive and produce more offspring with the characteristic.
c. Evolution would definitely occur resulting in white squirrels.
Answer:
A.
Explanation:
Because, they would have to adapt to their surroundings to survive and the white fur is a little thicker and help them blend in better form predators
b. If a mutation occurred which caused white fur to develop, such white squirrels would have a better chance to survive and produce more offspring with the characteristic.
What is natural selection?If a mutation occurred in a squirrel that caused it to have white fur, and if this trait helped the squirrel survive and reproduce more effectively in a cold, snowy environment, then it is possible that the trait could become more common in the population over time. This is known as natural selection.
However, it is important to note that whether or not a particular trait will become more common in a population depends on many factors, including the environment, the competition for resources, and the presence of predators.

What is it called when NADP+ becomes NADPH?
Answer:
This process is called phosphorylation(addition of phosphate) and since the energy comes from photons, this process is termed as photophosphorylation. Yes, the same NADPH donates its hydrogen to combine with CO2 to form glucose (C6H12O6) to become NADP again.
Explanation:
Answer:
The two reactions use carrier molecules to transport the energy from one to the other. ... The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.

Which of the following is true of active transport?
A In active transport, the cell does not have to do any work as nature moves the materials across the cell membrane.
B The energy used by the cell is in the form of the ADP molecule
C In active transport, the cell must push or pump the molecules from areas of high concentration to areas of low concentration.
D Molecules called pumps function to control active transport.
Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
When do land breezes develop? Which way does wind move during a land breeze?
Answer:
A low-pressure zone forms above the land surface from the rapid loss of heat. A high-pressure zone forms as the cooler land cools the air immediately above the surface. Winds aloft flow from the ocean to the land. Winds at the surface flow from high to low pressure, creating a land breeze

Why is the birth of modern science (c.1500-1700) important to how we understand knowledge and disciplinary divisions today
The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The birth of modern science (c.1500-1700) was important to how we understand the knowledge and disciplinary divisions today because the scientific method was established to get proper validation to the things in nature that in the past were attributed only to dive concepts expressed by the Church.
That old fashion way of thinking, validated by the church during the dark ages of Medieval Times, only created fear and fostered ignorance in people.
The advent of modern science changed this thing, basing its theories and answers on proper research that could be proven. That is how the human mind expanded and grew. No more myths and distorted religious beliefs that were so wrong.

Match each type of stress with its description.
stress caused by rocks pulling apart
compression
stress caused by rocks being pushed in
opposite directions
tension
stress caused by rocks pushing together
shearing
Correct!
Answer:Shearing: stress caused by rocks being pushed in opposite direction
Tension: street caused by rocks pulling apart
Compression: stress caused by rocks pushing together
Explanation:
Matching the description with each type of stress associated with rocks, we have:
1. Tension: street caused by rocks pulling apart.
2. Shearing: stress caused by rocks being pushed in opposite direction.
3. Compression: stress caused by rocks pushing together.
A rock can be defined as a solid naturally occurring landform that is made up of minerals.
In Geology, stress can be defined as a force that acts on a rock per unit area.
Generally, there are four (4) main types of of stress associated with rocks and these include:
1. Tension: it is a stress typically caused by rocks pulling apart, which makes them to either increase in length or break apart.
2. Shearing: it is a stress typically caused by rocks being pushed in opposite direction due to the effect of parallel forces.
3. Compression: this is a stress that is caused by rocks pushing together, which makes them to either fold or fracture (break).
4. Confining stress: it is a stress typically caused by rocks being pushed down by the weight of any material above it.
