Which statement best describes a characteristic of an ecosystem
Answer:
Infrastructure
Infrastructure is an important characteristic as it influences accessibility to the environment by land managers, and tourists alike. Unfortunately it can also increase the invasive potential introduced species, such as weeds and feral animals as road vehicles are well known to act as vectors for invasion of both weeds and feral animals. On the other hand roads improve access to implement various management programs, and also provide access for land users.

5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.
Answer
The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.
Explanation:
The brain stem, consisting of the pons and medulla, represent the main respiratory center. According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."
This is an example of a homostastic response controlled by both of the organ systems referenced above.

Because the imaginary axis of the earth is inclined to the sun at the equator, the northern and southern hemispheres shine in different ways. When it is summer in the northern hemisphere of our planet, then it is winter in the southern hemisphere
Answer:
Yes.
Explanation:
Yes, when it is summer in the northern hemisphere of earth, then it is winter in the southern hemisphere. This change of season occur due to tilting of earth. The season of northern hemisphere and southern hemisphere are different and opposite to each other because both are present at opposite location on the earth surface. The tilting region experience winter season whereas the other regions experience summer due to direct sunlight.
Describe how organ systems interact to get oxygen to the cells
The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.
What is oxygen in the body?Our bodies require a specific amount of oxygen to function effectively since oxygen is necessary for life. When you breathe (inhale), oxygen enters your body through your mouth or nose and travels through your lungs into your bloodstream.
Oxygen inhaled by the lungs is also carried by your blood. Your body's other cells receive oxygen and nutrition from your circulatory system, which then collects any waste products they produce, including carbon dioxide, and transports them to your kidneys and lungs for elimination.
Therefore, the blood collects food nutrients from the small intestine and transports them to every cell in the body.

Cuanto más fría es la temperatura en un lago, más oxígeno retiene el agua. Daniel se da cuenta de que pesca más peces en un lago que está a menos de 55 grados. Quiere realizar un estudio para capturar la mayor cantidad de peces posible este año. Necesita un poco de ayuda para escribir una pregunta comprobable y una hipótesis. Por favor ayudarlo.
Answer:
- Pregunta ¿la temperatura incide en la cantidad de oxígeno disuelto en el agua del lago?
- Hipótesis: temperaturas más frías están directamente asociadas con un incremento en la cantidad de oxígeno disuelto en el agua del lago
Explanation:
Para poder aplicar el método científico, lo primero que debemos hacer es formular una pregunta sobre algún fenómeno observado en el mundo natural. A continuación debemos formular una explicación posible o 'hipótesis' que permita responder la pregunta que formulamos anteriormente. A partir de la hipótesis podemos diseñar experimentos y/o observaciones empíricas que permitan probar la veracidad de nuestra hipótesis de trabajo. En este caso, por ejemplo, el experimento podría consistir en la medición y posterior comparación del nivel de oxígeno disuelto en el agua del lago durante la temporada de altas temperaturas versus la temporada de bajas temperaturas. Finalmente, los resultados observacionales/experimentales nos permitirán comprobar o rechazar la hipótesis de trabajo (en este caso, nuestra hipótesis es que el nivel de oxígeno disuelto es mayor a bajas temperaturas), obteniendo de este modo una conclusión a partir de nuestro trabajo.

Does the volume increase with trial number, decrease with trial number, or stay about the same? Explain why you think the results are the way there are. There are many possible reasons for the data trend you see. Give some that you think are reasonable.
Hi. You have not informed the experiment that this question refers to and this makes it difficult for your question to be answered. However, I researched your question on the internet and was able to find a question like yours that featured an experiment that assesses the volume of balloons that have been inflated by people's breath.
With the reading of the experiment, we can see that the volume of the balloons remains the same through the number of tests. This is because our lungs tend to express the same amount of air when we blow, just as we tend to breathe the same amount of air in normal situations. This probably happened because all the balloons were filled with air, while the individuals were in the same physical and mental state, that is, they were relaxed and still, which did not change the amount of air they breathed and expelled. This volume of air would be different if the participants in the experiment were exerting some physical effort or were stressed and anxious.
in the gizmo what conditions is the light intensity a limiting factor
The limiting factor was CO2 because when it was decreased or increased, it was still able to increase the oxygen production. I know that CO2 is the limiting factor because it always increases oxygen production.. Challenge: In each of the situations below, use the Gizmo to find the limiting factor.

2. brainstem
3. cerebrum
4. cerebrum
5. brainstem
6. cerebrum
7. cerebellum
Explanation:
The cerebellum is a region of the brain located behind the top part of the brainstem, which coordinates voluntary movements (e.g., posture, balance, coordination, speech). The cerebellum is well known to regulate the balance of the body. The brainstem is a type of automatic control center that connects the cerebrum with the spinal cord. The pons represents a group of nerves that serve as connection between the cerebrum and cerebellum. The pons are located in the brainstem (between the midbrain and the medulla oblongata). The cerebrum is the largest part of the brain and can be divided into right and left hemispheres. These hemispheres communicate with each other by the corpus callosum.

A circular ring of DNA that typically exists in bacteria and that codes for certain traits is known as a/n
Answer is Plasmid.
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.

your answer is like thisPea plants can have yellow seeds or green seeds. Which conclusion about the meaning of Y is correct if the allele combination Yy is for yellow seeds?
Answer:
yellow and dominant
Explanation:
In genetics, complete dominance occurs when a gene variant referred to as 'dominant allele' completely masks the expression of another allele referred to as 'recessive allele' in heterozygous individuals (i.e., individuals carrying one copy of the dominant allele and one copy of the recessive allele) at a specific locus. In this case, the yellow (Y) allele is dominant for the trait of 'color seed' with regard to the recessive (y) allele, which is responsible for the phenotype of green seeds, and therefore heterozygous individuals (Yy) will have yellow seeds.
