What happens in the stomach?
Answer The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

4. Compare the two examples of changes in beetle populations. Which of the two scenarios is an example of evolution? Defend your answer with an explanation.
Answer:
The second scenario, "Beetles of a different color", is an example of evolution.
Explanation:
Since evolution is defined as a change in gene frequency overtime, over generations, it is in the second example that we see such a phenomenon taking place. Brown beetles have become more common as opposed to the green beetle population that were the ancestors in this case.

Which cells are biconcave in shape and have no nucleus?
Answer:
It simply allows the red blood cell to have more hemoglobin. The more hemoglobin you have, the more oxygen molecules you can carry. Therefore, it allows RBC to transfer more oxygen. Lack of nucleus in RBC also allows the cell to have an unique bi concave shape that helps with diffusion.

Was it beneficial or harmful for the Chthamalus barnacle to add the Balanus barnacle? Explain.
Answer:
It was it harmful for the Chthamalus barnacle to add the Balanus barnacle.
Explanation:
The principle of competitive exclusion says that two different species that share the same niche can not live in the same place. If these species have the same requirements, they can not coexist. Two species can not coexist indefinitely on the bases of the same limited resource.
When two competing species coexist, this is because of niche partitioning or niche differentiation. If there is not any differentiation between them, the dominant species displaces the weak species.
In the exposed example, Chthalamus can live in the upper intertidal zone, where Balanus can not live because they can not tolerate desiccation. Balanus live in the lower intertidal zone, where Chthalamus can not live because of its vulnerability to predation. But these two species compete for the middle intertidal zone, where they can both live. Balanus excludes Chthalamus because the first species is much bigger and grows faster than the second one. So the middle intertidal zone is only inhabited by Balanus.
The area occupied by Chthalamus is smaller in the presence of Balanus. In the absence of Balanus, Chthalamus can live in a bigger area, occupying the middle intertidal zone.

Beer is a legal and regulated drug. It is produced and sold by commercial companies, and it is heavily advertised. Beer can lead to alcoholism and cause injuries through DUI accidents. Cocaine is an illegal and highly addictive drug. It is produced and sold by criminal organizations, and it is not advertised. Cocaine can lead to addiction, and possession is a crime punishable by law.
Cigarettes are legal but heavily regulated drugs. They are produced and sold by commercial companies, but they are subject to strict regulations about where they can be used. Cigarettes can lead to lung cancer and other health problems. Antacids are over-the-counter drugs. They are sold in pharmacies and grocery stores, and they are not regulated by the government. Antacids are used to treat heartburn and other acid-related problems.

why/how is biodiversity essential to the health of an ecosystem
Answer:
Biodiversity is the amount of variety of life on Earth.
Explanation:
Biodiversity boosts ecosystem productivity where each species, no matter how small, it has an important role to play.
For example,
a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.
Because it provides a wide variety of ecological services essential to both ecosystem function and human well-being, biodiversity is important to the health of an ecosystem.
What is Biodiversity?The term "biodiversity" describes the range of living things in an ecosystem, such as plants, animals, fungi, and microorganisms, as well as the genetic diversity found within each species.
Here are some justifications for why ecosystem health depends on biodiversity:
1. Nutrient Cycle: The ability of an ecosystem to cycle nutrients depends on biodiversity.
2. Temperature control: By absorbing carbon dioxide and generating oxygen through photosynthesis, biodiversity helps regulate temperature.
3. Soil health: Biodiversity is essential for the preservation of healthy soil.
4. Controlling pests and diseases in ecosystems: Biodiversity can help in managing pests and diseases.
5. Benefits to the Economy: Humans benefit economically from biodiversity in a number of ways, including access to food, medicine, and other natural resources.
Therefore, biodiversity is important for the health of ecosystems, and its loss can have serious detrimental effects on both ecosystem functioning and human well-being.

Calculate if 1000 units of energy are available at the producer level of the energy pyramid about how many units are available for first level consumers? Second level consumers? Third level of consumers?
Answer:
first level consumers?- abou 100 units
Second level consumers- about 10 units
Third level of consumers- about 1 unit
Explanation:
Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.
A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.
However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.
Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.
Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?
Answer:
The question lacks options, the options are:
A. The green trait is the dominant trait.
B. The offspring will inherit one gene from each parent.
C. The offspring will have both green and yellow seeds.
D. Each offspring will have a unique set of alleles.
The answer is optionB
Explanation:
This question describes a monohybrid cross i.e. involving a single gene coding for seed colour in pea plant. One allele codes for green seeds and the other for yellow seeds.
Based on the question, a plant that has the same alleles for yellow seeds is crossed with another plant that has same alleles for green seeds. The offsprings produced will have two different alleles i.e. heterozygous, contributed by each parent.
Hence, the offsprings will inherit one form of the gene from each parent.

Which strategy do geologists use to locate the center of an earthquake? A. They only analyze local data. B. They collect data from seismographs. C. They measure arrival times of surface waves. D. They draw squares on maps for measurements.
Answer:
the answer is (B) "They collect data from seismographs."
Explanation:
i got a 100 on the Quiz "Earthquakes"
The strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.
What is an Earthquake?An earthquake may be defined as an activity that involves the unanticipated and brutal shaking of the ground, generally causing huge destruction, as an outcome of movements within the earth's crust or volcanic action.
Geologists utilize an instrument that is known as a seismograph that measures the strength of an earthquake. With the help of this instrument, they find the center of an earthquake on the basis of the highest strength.
Therefore, the strategy that geologists use to locate the center of an earthquake is they collect data from seismographs. Thus, the correct option is B.
