On the average, how much energy is lost from each trophic level? explain why
Answer:
I think it's 10% because some of it turns into heat energy
Explanation:
On average, about 90% of the energy is lost from each tropic level. The remaining 10% is available for the next trophic level.
The tropic level of the organisms is the position of organisms occupied in the food web. When an organism consumes other organisms as its food, the energy stored in the form of chemical energy in the organic molecules is converted into the energy used for cellular respiration.
This conversion is not efficient and the energy is lost in the form of heat. Some of the energy is used for growth and maintenance. While other energy is excreted.
Thus, when an organism consumed organic matter, 90% of the energy is lost and 10% of the energy is involved in the building of body tissues. This 10% of energy is passed to the next level.

Limiting factors are divided into two categories. What are they? Give an example of each.Limiting factors are divided into two categories. What are they? Give an example of each.
Answer:
Limiting factors fall into two broad categories: density-dependent factors and density-independent factors. These names mean just what they say: Density-independent factors have an impact on the population, whether the population is large or small, growing or shrinking.
the density-dependent factor example is:
Density-dependent factor, also called regulating factor, in ecology, any force that affects the size of a population of living things in response to the density of the population (the number of individuals per unit area).
the independent factors example is:
Pollution. Like other density independent factors, pollution is a good example of a density independence.

Provide an example of how a genetic mutation could be positive, then explain how that mutation could cause a change in a population over time.
Answer: Some mutations happen during cell division, when DNA gets duplicated. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others.
Reflection Questions
1. Explain how biological evolution is supported by the fossil record.
2. Why is natural selection a mechanism for biological change?
3. How does chemical evolution explain the origin of life on Earth?
4. Explain why scientific theories, such as biological and chemical evolution, represent the
strongest explanation of the changes observed in the fossil record.
5. How can scientific theories on evolution and the fossil record change over time?
Answer:
1) The word ‘evolution’ was first mentioned in the book ‘The Origin of Species’ in 1859, by Charles Darwin. Darwin put forward the concept of evolution during his journey to the Galapagos Islands.
2)Natural selection is an important mechanism of evolution. It states that the organisms that are able to survive and reproduce with the changing environmental conditions are selected by nature while the ones that cannot survive are eliminated.
3) Evolution mainly deals with the origin of life on earth. The conditions and the forms of life on earth were entirely different from what we see today.
please forgive me I cant answer 4th one..
5)Charles Darwin, an English naturalist of the 19th century made an extensive study of nature for over 20 years.
1. The fossil record provides crucial evidence for biological evolution. Fossils are the preserved remains or traces of past organisms, providing a record of life on Earth over millions of years.
By studying fossils, scientists can observe changes in organisms and their characteristics over time. Fossils show a progression of simpler life forms in older layers to more complex ones in more recent layers.
2. Natural selection is a mechanism for biological change because it leads to the adaptation of populations to their environments over time. It is based on the concept that individuals within a population exhibit variation in traits, and those traits that enhance survival and reproduction are more likely to be passed on to future generations.
Through natural selection, individuals with advantageous traits have higher chances of surviving and reproducing, leading to the increased frequency of those traits in subsequent generations.
3. Chemical evolution, also known as abiogenesis or prebiotic evolution, explains the origin of life on Earth by proposing that life arose from non-living matter through a series of chemical reactions.
According to this theory, in Earth's early conditions, simple organic molecules formed from inorganic compounds through processes like lightning, volcanic activity, and reactions in the atmosphere and oceans.
These molecules then underwent further reactions, leading to the formation of more complex molecules like amino acids and nucleotides, which are the building blocks of proteins and nucleic acids, respectively.
4. Scientific theories such as biological and chemical evolution represent the strongest explanations for the changes observed in the fossil record because they are supported by extensive evidence from multiple scientific disciplines.
These theories have withstood rigorous testing, scrutiny, and peer review over many years. They are based on a large body of evidence, including the fossil record, comparative anatomy, genetics, molecular biology, and observations of natural populations.
5. Scientific theories on evolution and the fossil record can change over time as new evidence is discovered, technologies advance, and scientific understanding improves.
The process of scientific inquiry involves continuous investigation, testing, and refinement of theories based on new data and observations.
As scientists gather more evidence from fossil discoveries, genetic studies, experimental research, and other fields, our understanding of evolution and the fossil record can deepen and evolve.

Genetic recombination would be most closely associated with which process in disease-causing microorganisms?
A.binary fission in fungi
B.sexual reproduction in fungi
C.spore formation in bacteria
D.viral replication in host cells
Genetic recombination is most closely associated with: Choice D: Viral replication in host cells
Definition:
Genetic recombination (otherwise termed genetic reshuffling) is simply the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
In retroviruses, recombination actually occurs at the point during replication when the retrovirus genome is in a DNA form and takes place by the same break-rejoin technique as in cells and DNA viruses.
Recombination can occur both between two related retroviruses and between the retrovirus DNA and the host DNA.

There are several microorganisms all around us, they all come in different shapes and sizes. It might be quite difficult to identify one organism from the other. To solve this problem scientists came up with a method of naming and grouping microorganisms into different categories, this method is known as TAXONOMY.
Taxonomy is the method of classifying different organisms into various groups. The scientist that first came up with this method is known as Carl Linnaeus. The different categories include; kingdom, phylum, class, order, family, genus, species.
Hence scientists group similar organisms together through a process called TAXONOMY.

Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks.
A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.
B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.
C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.
D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.
E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.

What is the difference between Hinduism and Nirvana
Answer:
The most ancient texts of Hinduism such as the Vedas and early Upanishads don't mention the soteriological term Nirvana. This term is found in texts such as the Bhagavad Gita and the Nirvana Upanishad, likely composed in the post-Buddha era. The concept of Nirvana is described differently in Buddhist and Hindu literature. Hinduism has the concept of Atman – the soul, self asserted to exist in every living being, while Buddhism asserts through its anatman doctrine that there is no Atman in any being. Nirvana in Buddhism is "stilling mind, cessation of desires, and action" unto emptiness, states Jeaneane Fowler, while nirvana in post-Buddhist Hindu texts is also "stilling mind but not inaction" and "not emptiness", rather it is the knowledge of true Self (Atman) and the acceptance of its universality and unity with metaphysical Brahman.

make it simple
Answer:
an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Hello there!!
I love protozoa so this should be fun.
1. Protozoans are unicellular beings that live in wet environments.
2. Protozoans have 2 prevalent ways of feeding:
a) the most common is utilized by heterotrophs like amoeba. An amoeba extends its elastic body until it completely surrounds the victim. Then the amoeba simply has to digest its food.
b) The second most common is through cilia. Paramecia use this method. The hair-like cilia in its mouth catch hold of food and push the meal into the paramecium's digestive tract.
3) The only protozoan to have its own family is Euglena.
4) Euglena has its own family because it has chloroplasts (meaning it can undergo photosynthesis) but it can also feed like a heterotroph. Because Euglena exhibits both plant and protozoan qualities, it has its own category.
5) Rotifers move by two spinning wheels of cilia. This type of propulsion makes the rotifer a speedy little protozoan.
