Which of the following terms describes the tendency of plant stems and flowers to turn toward sunlight?


geotropism

chemotropism

gravitropism

phototropism

Answer:

The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. ... When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode.

Explanation:

A national rainforest in Puerto Rico is MOST closely associated with ecotourism. The correct answer is c).

Ecotourism is a form of tourism that is focused on responsible travel to natural areas that conserves the environment and improves the well-being of local people. The goal of ecotourism is to educate visitors about the natural and cultural heritage of a particular area and to promote conservation efforts.

A national rainforest in Puerto Rico would be an ideal location for ecotourism because it offers visitors the opportunity to explore a unique and diverse ecosystem while also supporting conservation efforts and providing economic benefits to local communities. In contrast, a water park, hunting grounds, cruise ship, or jet ski rental shop may not be focused on responsible travel or conservation efforts and may have negative impacts on the environment and local communities.

Therefore, the correct answer is c) A national rainforest in Puerto Rico.

Answer:

Energy in an ecosystem: is part of an open system, is recycled and reused, is transferred through the food chain and is lost as heat.

The best way to test the hypothesis that the number of coils has a cause-and-effect relationship with the strength of magnetic devices is by using one nail and testing more of a variety of coil numbers. So the correct option is option D.

In addition, the greater the number of turns of the wire composing the coil, the more intense the magnetic field is produced. The reason for this is that the magnetic field created by each turn of the wire superposes the center of the previous turn.

The strength of an electromagnet is determined by the number of rotations in the coil. For example, if rotations in a coil are doubled, then the strength of the electromagnet is also doubled.

Peccaries eat cacti with a smaller number of spines, and wasp larvae eat cacti with a greater number of spines best accounts for the different frequency distributions in the graph.

Therefore option B is correct.

A herbivore is  described as an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet.

The frequency distributions of the cactus populations in the presence and absence of the two herbivores indicates  that the presence of the herbivores which affects the distribution of spine numbers.

In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide. ... This carbon can then be ingested and stored in animals that eat the plants. When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals.

When animals die, their bodies degrade into the soil, encasing the carbon in layers that eventually transform into rock or minerals. hence option b is correct.

Stone including limestone and its minerals is created when sediment and shell layers are bonded together over time.

Gases like carbon dioxide are among the forms of carbon that are stored in the atmosphere. Animals that consume the plants can then absorb and store this carbon.

When animals die, their bodies degrade into silt, encasing the carbon in layers that eventually transform into rock or minerals. Some of this silt may eventually turn into fossil fuels like coal, oil, or natural gas, which when burned, release carbon back into the atmosphere.

Therefore, when an animal dies to decompose into the soil which becomes rocks through carbon from living organisms moves into rocks, hence option b is correct.

Answer:

Upwelling

Explanation:

Upwelling is the process through which cold water gets to ascends from the bottom, providing nutrients to the superficial stratum.

Upwelling is an ascending displacement of marine currents. The phenomenon can also occur in lakes or freshwater dams.

Wind blowing over the coast can cause surface water to move out to sea. This motion is complemented by a slow ascension of cold water coming from the bottom forward to the coast. This currents movement is known as upwelling.

Upwelling water is extremely cold and rich in nutrients, which result from remineralization, by bacterial action, of organic matter that accumulates in the deepest stratum of the water body.

The contact of minerals with photosynthesizing organisms in superficial layers produces a significantly high primary productivity.

Answer:

Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don't just eat nature's waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals.

Explanation:

To systematically investigate the yellowing of the plant's leaves, you can follow these steps:

1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.

2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"

3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.

4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.

5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.

6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.

By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.

Hope it helps!!! :)

A systematic method to ask the right questions, make educated guesses, conduct scientific experiments, and arrive at a conclusion is to follow the scientific method as follows:

A hypothesis could be; The yellowing of the plant's leaves is a result of reduced exposure to sunlight.

The yellowing of leaves in a potted plant kept away from sunlight is primarily due to a process called chlorosis which is the loss or reduction of chlorophyll in plant tissues.

When a potted plant is kept away from sunlight or receives insufficient light, the plant is unable to carry out photosynthesis. Consequently, the chlorophyll content in the leaves decreases, and they start to lose their green color.

Answer:

YES

Explanation:

Glycogenolysis can still occur during exercise even if a person is administered a drug that blocks the Beta receptors for norepinephrine. This is because glycogenolysis is mainly regulated by the hormones epinephrine and glucagon, which are released from the adrenal glands and do not require norepinephrine for activation. Therefore, blocking the Beta receptors for norepinephrine has no effect on glycogenolysis.
