Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.

Create a city of your choice and assign each of the major organelles from our guided notes to a part of the city.
Draw your city on a piece of paper. Use your creativity and imagination!
Write your analogy to show the similarity between the cell part and the part of the city. Be sure to explain the reasoning behind your analogies. The cell analogies and functions should be written.
Example- The nucleus controls the cell just like how town hall coordinates a city.
You will create this on a sheet of paper or on a digital document that works best for you.
Make sure to include each organelle, what it does, and what it could represent within a city! Be creative!
Answer:
A cell is like a city
Example
The nucleus controls the cell just like how the town hall coordinates a city.
1) The vacuole is a supply centre just as they are the large groceries in the city.
2) The mitochondrion is the supplier of ATP to the cell, as well as the electric power plant in the city.
3) The Golgi Apparatus is responsible for packaging and modifying proteins as well as distributing chemical messages in the cells just as the post office works in the city.
4) The ribosomes they produce from raw material RNA finished products named proteins as the factories do.
5) The cell wall protects the cell as the fortifications do in the city.
6) The cell Membrane allows the communication of the cell with the environment through the transport of information just like the city limits, through tollbooth or carrier proteins.
7) Lysosomes process cellular material down to simpler and smaller molecules like the city's recycling plant does.
8) The endoplasmic reticulum allows the movement of proteins in the cell as do the roads in the city.
Explanation:
Unfortunately, I do not know the organelles that you present in your guide, however, I give you an example with the most important.
The vacuole is responsible for storing food, liquids and wastes and/or enzymesThe mitochondrion is the energy-producing organelle synthesizing ATPThe Golgi apparatus handles synthesized proteins to transport them to other places in cellsRibosomes are responsible for reading DNA and producing proteins.The cell wall gives structure and protects the cell.The cell membrane regulates transport into and out of the cell.Lysosomes are responsible for degrading intracellular material. The endoplasmic reticulum is a network of membranes that allows the movement of proteins and other molecules.In protein synthesis, proteins are made (as the name suggests).

What are molecules and how are they used in running? Evidence
What is homeostasis and how does homeostasis work to maintain internal stability? Evidence
Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.

How would different climate zones be impacted by climate change?
Answer:
Changes in Earth's climate have different effects in different areas of the world. Some places will warm much more than others, some regions will receive more rainfall, while others are exposed to more frequent droughts. Regional changes in temperature and precipitation are having impacts on people and ecosystems.
Answer:
A new global warming study predicts that many current climate zones will vanish entirely by the year 2100, replaced by climates unknown in today's world. ... Novel climates appear throughout the tropics and subtropics, while the climates now found in tropical mountain ranges and near the poles may vanish

Which weathering process uses a solvent to wear things down
A. Freezing ice
B. plants and animals
C. Moving air
D. Moving water **
I picked D. I need this answer quick!!!! Will give brainliest
Moving water is the weathering process uses a solvent to wear things down. So, the correct option is D.
What is Weathering?Rocks, soils, minerals, wood, and manmade materials all deteriorate due to weathering when they come into touch with water, air gases, and living things.
The natural dissolution of rocks and/or minerals found on the Earth's surface is known as weathering. To disintegrate rocks that are located on the surface, weathering is essential. Moreover, chemical weathering alters the molecular make-up of rocks and/or soils.
Even the most substantial of the boulders are being broken up into smaller pieces by the sun, rain, frost, and wind before they are hauled away. Weathering is the name given to this process.
Thus, the correct option is D.

Although they often live in the same habitat, the American toad breeds earlier in the spring than the Fowler's toad does.
What can be inferred from this information?
a
The American toad will cause the extinction of the Fowler's toad.
b
The two species interbreed throughout the spring season.
c
The two species do not interbreed because of geographic isolation.
d
The two species do not interbreed because of temporal isolation.
The two species do not interbreed because of temporal isolation.
What is temporal isolation?Temporal isolation, in biology, a type of reproductive isolation mechanism among organisms in which the differences in the timing of critical reproductive events prevent members of closely related species, which could otherwise breed with one another, from mating and producing hybrid offspring.
The American toad breeds earlier in the spring than the Fowler's toad does. Therefore, they do not interbreed, even though they often live in the same habitat.

(NO FILES PLEASE) All organisms' cells contain DNA. Every organism's DNA is made of nucleotides. Although, the four species on this phylogenic tree are different, which components of their DNA are the same?
Question 4 options:
(A) sugar deoxyribose and the base thymine.
(B) sugar deoxyribose and the base uracil.
(C) sugar ribose and the base thymine
(D) sugar ribose and the base uracil.
The components of DNA that will be similar in the given organisms will be deoxyribose sugar and base thymine. So the correct answer is option A.
This is because humans, chimpanzees, and gorillas have DNA as their genetic material. And DNA is composed of a phosphate group, a deoxyribose sugar, and the four bases adenine, guanine, cytosine, and thymine.The sugar ribose is not found in the DNA and is known to occur in the RNA. Also base uracil is not found in the DNA.
So ribose sugar and uracil base can never be found in the genome of the organisms which posses DNA as their genetic material.

What does the law of conservation of energy state?
It is important to use as little energy as possible.
Organisms save the energy that they create.
Organisms change energy into mass.
Energy cannot be created or destroyed
Answer:
Energy cannot be created or destroyed
Explanation:
Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
