Ecosystem function relies on the flow of nutrients from one _________ to another in a cycle. Group of answer choices Country Chemical Reservoir Species Altitude
Ecosystem function is highly dependent on the flow of nutrients from one species to another in a cycle.
What is an ecosystem?An ecosystem refers to a biological community that typically consists of both living organisms (biotic factors) and the physical environment (abiotic factors) in which they interact.
What is a species?A species can be defined as a biological classification of related organisms with similar characteristics that are capable of breeding with one another in a cycle.
Generally, the proper functioning of an ecosystem is highly dependent on the flow of nutrients from one species to another in a cycle and as such determines their ability to survive.

How do green plants produce their own food?
Answer:
Photosynthesis
Explanation:
The process by which land plants produce their own food using sunlight and carbon dioxide is known as photosynthesis. The leaves of green plants contain chlorophyll, which absorbs sunlight for producing food. This food is then used by the plant itself as well as other animals, including humans.

Explanation:
dust, dirt and gases are the examples of indoor air pollution whereas carbon dioxide, methane and neon are the gases that make up the remaining 0.1 percent.
What is indoor air pollution?Indoor air pollution is dust, dirt and gases in the air inside home or workplace that could harm to the health of people. It causes lung diseases like asthma, COPD, lung cancer, heart disease and stroke.
Carbon dioxide, methane and neon are the gases that make up the remaining 0.1 percent. This means that these gases are present in very minute concentration in the atmosphere.
So we can conclude that dust, dirt and gases are the examples of indoor air pollution whereas carbon dioxide, methane and neon are the gases that make up the remaining 0.1 percent.

Which of the characteristics describe energy-carrier molecules?
can be coupled to energy-requiring reactions within a cell to help drive the reactions forward
accumulate in large quantities within a cell for long-term storage of energy
are quickly broken down once the molecules release their energy
include molecules, such as ATP, that contain high-energy chemical bonds
are generated when macromolecules, such as proteins, are broken down
Answer:
are quickly broken down once molecules release their energy
Explanation:
The characteristics of energy-carrier molecules are that they are quickly broken down once the molecules release their energy, which isoption. Energy-carrier molecules, like ATP, are quickly broken down into ADP (adenosine diphosphate) and inorganic phosphate (Pi) once they release their energy.
Energy-carrier molecules, such as ATP, store energy in high-energy chemical bonds. When these bonds are broken, energy is released and can be used for cellular processes.Energy-carrier molecules are not typically generated when macromolecules, such as proteins, are broken down. Energy carriers like ATP are produced through cellular respiration, primarily in processes such as glycolysis, the Krebs cycle, and oxidative phosphorylation.

Describe three ecological benefits of preserving rainforest ecosystems discussed in the
lesson
Answer:
Explanation:
Benefits of rainforest ecosystems. 1. Preservation of species. Because they are so biodiverse, healthy rainforest ecosystems are the perfect places to preserve huge numbers of species that would otherwise be endangered.
Rain forest ecosystem have several advantages like preserve species, biodiversity is high etc.
what are the types rainforest ecosystem ?
The major constituents of a rainforest ecosystem are tall evergreen trees, it is formed due to heavy annual rainfall, high temperature, poor quality soil and rich in biodiversity.
There are different types of rain forest such as Tropical rainforests which is present near to the equator, the climate is hot and humid.
Temperate rainforests present in extreme temperate zones, close to coastal areas and the climate is cooler than tropical rainforests.
Third is Flooded forest where dry forest can be flooded by heavy rains or due to tidal river surrounding the forest, climate is highly humid.
Lowland rainforests refers to either tropical or temperate present near to valley. Cloud forests or Montane rainforests is located on the top of mountain top, partially in cloud.
Finally, mangrove forests are also called as mangrove swamps, trees are waterlogged ground.

CSI Miami: Using DNA to Solve a Robbery
The year is 2023. You are a detective for the Miami Dade Police Department. You’re on the scene of a crime where a man single-handedly just robbed a bank. Luckily, being the ingenious detective that you are, you were able to find a little spot of the man’s blood where he cut his arm as he made his escape through a broken window. You take the blood to the lab so tests can be run.
Unfortunately, no one was able to see the face of the man, so there are no suspects yet. Thanks to a study done in 2022, scientists have now figured which genes in DNA code for which characteristics in a person.
On the next page is a strand of the sample of DNA extracted from the blood at the crime scene. Follow the steps below to help you come up with a sketch of the man who perpetrated this crime.
methionine-leucine-proline = Protein that causes DARK SKIN
methionine-leucine-leucine = Protein that causes LIGHT SKIN
valine-proline-proline-lysine = Protein that causes GREEN EYES
proline-leucine-valine-proline = Protein that causes BLUE EYES
proline-lysine-proline-proline = Protein that causes BROWN EYES
lysine-arginine-threonine-valine-serine-serine = BLOND HAIR
lysine-arginine-threonine-valine-serine-cystine = BLACK HAIR
lysine-arginine-threonine-valine-serine-valine = BROWN HAIR
asparagine-isoleucine-arginine = CURLY HAIR
asparagine-asparagine-isoleucine = STRAIGHT HAIR
leucine-arginine-glutamic acid-arginine = BIG NOSE
leucine-asparagine-arginine-glutamic acid = SMALL NOSE
leucine-asparagine-asparagine-glutamic acid = MEDIUM NOSE
proline-tyrosine-tyrosine-(stop) = SMALL EARS
proline-proline-tyrosine-(stop) = MEDIUM EARS
proline-tyrosine-phenylalanine-(stop) = BIG EARS
Step 1: Decode the DNA into mRNA
Step 2: Decode the mRNA into the corresponding amino acids from pg. 211 of your book. Write the amino acids in the order of the codons from the mRNA.
Step 3: On a separate sheet of paper, draw a sketch of what this person might look like based on the traits you came up with.

1) When you performed step 1, what enzyme were you imitating?
2) In step 2, what molecule would have brought the amino acids that the codons asked for?
3) In step 2, what molecule would have helped the amino acids line up and attach to one another?
4) In step 2, what connected the amino acids together?
