what happens to most of the energy as we move up trophic levels
Answers
As we move up trophic levels in an ecosystem, most of the energy is lost.
Energy transfer between trophic levels follows the fundamental ecological principle known as the 10% rule or the 10% law of energy transfer. According to this rule, only approximately 10% of the energy available at one trophic level is transferred to the next trophic level.
The primary reason for this energy loss is that energy is expended and lost as heat during various biological processes, such as metabolism, respiration, and movement, at each trophic level. Additionally, not all consumed energy is efficiently converted into biomass; some is used for growth and reproduction, while some is excreted as waste.
This energy loss has important ecological implications. It limits the number of trophic levels that can be sustained in an ecosystem and explains why there are generally fewer individuals and biomass at higher trophic levels. It also underscores the significance of primary producers (such as plants) in capturing and converting sunlight energy into chemical energy at the base of the food chain.

Where are the high tides if the moon is in first quarter?
Answers
The first and third halves of the moon, when the moon seems to be "half full," are when neap tides occur.
When tides are at their peak, where is the moon?Every month, at perigee, when the moon is closest to Earth, tidal-generating forces are stronger than usual, resulting in tide ranges that are higher than typical. When the moon is at its furthest distance from Earth, or apogee, about two weeks later, the lunar tide-raising effect is weaker and the tidal ranges are smaller than usual.
How does a first quarter moon affect things?The Moon is facing the Earth and Sun at a 90-degree angle during this phase. The Moon appears to be partially lighted and partially in shadow. We observe what appears to be the right half during the first quarter.

Blood vessels are connected to nerve fibers which are regulated by the
nervous system. When innervated they respond by doing what?
Answers
Answer:
When blood vessels are innervated they respond by contracting and relaxing their muscle wall, as a result of the activity of the autonomic nervous system.
Explanation:
The nerves that are responsible for the innervation of the blood vessels are called nervi vasorum, and are composed of nerve fibers of the sympathetic and parasympathetic nervous systems.
The innervation of the blood vessels specifically acts on the muscular wall of the vessel, so it contracts or relaxes depending on the activity of the nervous system:
Sympathetic nervous system stimulates vascular contraction.Parasympathetic nervous system makes the vascular smooth muscle relax.The action of the autonomic nervous system has an effect on blood pressure, being a determinant of normal or pathological behavior of the arteries.

Answers
Answer:
A. They can outcompete native species.
Explanation:
Remember that ALL species need an ecosystem they can easily adapt in to survive, especially invasive ones. Adaptation is a heritable trait that helps organisms adjust to new changes in their environment.
Invasive species can compete with native organisms for resources, cause extinctions, reduce biodiversity, and disrupt ecosystem processes. They can also threaten, or even prevent human use of the resources in the ecosystem.
In order for an invasive species to be successful in their new environment, they need to be able to reproduce and grow rapidly to take over quickly.

Answers
Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.
Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.
STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.
What is the difference between Carbonia and Insularia Peppered moths?
Answers
Carbonia and Insularia Peppered moths are two distinct forms or subspecies of the peppered moth (Biston betularia). The main difference between these forms lies in their geographic distribution and coloration.
Carbonia Peppered Moth: Carbonia is a form of peppered moth that is predominantly found in industrial areas where pollution and soot are prevalent.
These moths have dark or melanic coloration, which provides them with camouflage against the darkened tree trunks that were common in industrialized regions. The dark coloration of Carbonia moths helped them evade predators and increased their survival rates in polluted environments.
Insularia Peppered Moth: Insularia is another form of peppered moth that is primarily found in non-polluted or rural areas.
These moths have lighter or speckled coloration, which allows them to blend in with lichen-covered tree trunks that are common in unpolluted habitats.
The light coloration of Insularia moths provided them with camouflage against their natural background, reducing predation risk.
The difference in coloration between Carbonia and Insularia Peppered moths is an example of industrial melanism, where moth populations adapted to their changing environment due to human industrial activities.

Small, prolific mussels called zebra mussels were first introduced into the Great Lakes by a foreign cargo ship. They became a serious problem because they attached themselves to smooth, hard surfaces, and often clogged water intake pipes. Congress determined that zebra mussels posed a great threat to the economic welfare of the Great Lakes region and passed a statute requiring all Great Lakes water intakes to be coated with a special chemical compound that repels zebra mussels. Studies by biologists at a major state university showed that while the special chemical compound that the federal government has required was effective, it also was toxic to other aquatic life. The biologists recommended that Great Lakes intake pipes be coated with a less toxic and less expensive copper-based paint. On the basis of those studies and the recommendation, three Great Lakes states adopted laws permitting municipal water districts to coat their intake pipes with copper paint.
Can municipalities using copper-based paint on their intake pipes successfully be prosecuted for violating the federal law?
A. No, because the Tenth Amendment prevents Congress from interfering with integral government functions.
B. No, because the municipalities are taking effective steps to combat zebra mussels in compliance with the spirit and purpose of the federal law.
C. Yes, because Congress is in a better position to regulate the entire Great Lakes region than the individual states.
D. Yes, because Congress may adopt laws regulating navigable waters.
Answers
Answer: Yes, because Congress may adopt laws regulating navigable waters.
Explanation:
It should be noted that municipalities using copper-based paint on their intake pipes can successfully be prosecuted for violating the federal law because Congress may adopt laws regulating navigable waters.

It takes Matthew 0.2 seconds more to hear the train whistle on a cold winter day compared to a warm summer.
What is the difference in the time to hear the sound?The difference in the time to hear the sound is calculated as follows:
At 38°C (311 K), the speed of sound = 347 meters per second.
At -4°C (269 K), the speed of sound = 331 meters per second.
The time it takes for Matthew to hear a train whistle is calculated with the equation below:
time = distance/speed
The time it takes for Matthew to hear the whistle on a warm summer day will be:
time = 900 / 347
time = 2.59 seconds
On a cold winter day, the time it takes for Matthew to hear the whistle will be:
time = 900 / 331
time = 2.72 seconds
The difference in time = (2.79 - 2.59) seconds
The difference in time = 0.2 seconds

A- Plants develop polyploidy only through selective breeding.
B- Plants may naturally increase their ploidy levels with each generation.
C- Plants can't survive 3, 4, or 5 times the haploid number of chromosomes,
D- Introducing polyploidy to plants can increase certain desirable traits.
Answers
The conclusion that is MOST STRONGLY supported by the data in the table is "D- Introducing polyploidy to plants can increase certain desirable traits."
option D is correct.
The table shows that introducing polyploidy in plants can increase the size of the leaves, cells, fruits, flowers, and seedless fruits.
Therefore, we can conclude that polyploidy can improve certain desirable traits in plants. This is also supported by the fact that many plants that are grown commercially are polyploid, which is an evidence that introducing polyploidy in plants has its advantages.
Option A is incorrect as polyploidy can be developed naturally.
Option B is not the MOST STRONGLY supported conclusion as it is not always the case that plants will increase their ploidy level with each generation.
Option C is incorrect because many polyploid plants exist and are able to survive with a higher chromosome number.

which organ system is the slow-acting control system of the body?
Answers
Answer:
endocrine system
Hope this helps :) !!!
The Endocrine System is the slow-acting control system of the body. Please find a long answer below:Long Answer:The endocrine system is the slow-acting control system of the body. It is a network of glands and organs in the body that create, store, and secrete hormones into the bloodstream.
These hormones are responsible for regulating various body functions and maintaining homeostasis. The endocrine system is composed of several glands that are located throughout the body. These glands include the pituitary gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, and the ovaries or testes in males and females.Each gland produces a specific set of hormones that perform specific functions in the body. For example, the adrenal gland produces hormones that regulate stress responses and the thyroid gland produces hormones that regulate metabolism. Hormones are released into the bloodstream and travel to different parts of the body where they bind to target cells and initiate a response.
The endocrine system is slower than the nervous system in terms of response time. It can take several seconds to several minutes for the hormones to take effect. However, the effects of the hormones can last for several hours or days.The endocrine system is responsible for a wide range of body functions, including growth and development, metabolism, reproduction, and immune function. Dysfunction of the endocrine system can lead to a variety of health problems, including diabetes, thyroid disorders, and adrenal disorders. In conclusion, the endocrine system is the slow-acting control system of the body that regulates various body functions by producing and secreting hormones into the bloodstream.

The invading nations aimed to devastate the agricultural productivity and food supply of the local population.
Salting the fields was a deliberate act of agricultural sabotage with long-lasting consequences. The process involved spreading large amounts of salt over the farmland, which effectively rendered the soil infertile, inhibiting the growth of crops and making it nearly impossible to cultivate food. This strategy was particularly effective in ancient times when agriculture was the primary means of subsistence.
The devastation caused by salting the fields not only impacted the present generation but also affected future generations as the soil remained barren and required significant efforts to be reclaimed for agricultural use. This tactic was not only meant to suppress immediate resistance but also to instill fear and discourage other potential adversaries from rebelling against the invading nation.
