Hundreds of years ago, a volcanic eruption killed many plants and animals on a tropical island. Today, the island looks much as it did before the eruption. Why is this true? Destroyed ecosystems always return to their exact original state. Altered ecosystems only regain stability from the development of grasses. Geographic barriers prevent the migration of animals to island habitats. Destroyed environments can recover through ecological succession.
Answer:
Destroyed environments can recover through ecological succession.
Explanation:
Ecological succession describes a progressive change in the species in an ecological community over time.
This can happen after some disturbance such as a fire, earthquake, or volcanic eruption. It can mean that a e can return to the state it was before the event.

Explanation:
A food chain in an ecosystem flows from green algae, to freshwater snails, to small fish, and finally to large fish.
The primary consumer would is freshwater snails.
Explanation:
Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often get killed by secondary consumers.
Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes.
How does the Golgi Body and Plasma membrane work together ?
Answer/Explanation:
The Golgi body is a system of flattened sacs that is involved in the packaging, modification, and transport of proteins. It is particularly important for proteins that have to be transported outside of the cell.
Proteins from the Golgi that are to leave the cell are transported in vesicles. When they reach the membrane, the vesicles fuse with it and release the proteins outside of the cell

List the six nitrogen bases that would pair with the following sequence of bases in a strand of DNA : T C G A C A
Answer: thymine (T) Cyostine (C) guanine (G) adenine (A)
Explanation:
Guanine (G) is complementary to cytosine (C), and adenine (A) is complementary to thymine (T). Hence, the nitrogenous bases that would form for the DNA bases TCGACA are AGCTGT.
How does base pairing take place in DNA?
A DNA double helix is joined together by the hydrogen bonds that are formed between the nitrogenous bases in the opposite strands. Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) are the nitrogenous bases present in the DNA. Both adenine and guanine are purines. They make bonds with pyrimidine.
Adenine (A) of one DNA strand makes a double bond with Thymine (T) of the opposite DNA strand. The guanine (G) of one DNA strand makes three hydrogen bonds with the cytosine (C ) of the opposite DNA strand. As there are three hydrogen bonds present in guanine and cytosine (GC), they require more energy to break the bond. Adenine and thymine (AT) have two hydrogen bonds, hence they require less energy than GC bonds.
Hence, in a DNA strand, the complementary strand of TCGACA is AGCTGT.

Differentiate between pathogens and vectors
Answer:
A pathogen is an agent that causes disease, such as a virus, bacterium, protozoan, or parasite. A vector is an organism, often an arthropod, that carries a pathogen to its host. So, for example, for malaria the pathogen is a protozoan called Plasmodium, and the.

1. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem.
2. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
3.Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems. (Not from google )
Answer:
1. Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts.
Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.

A. it is found on articular surfaces of bone
Answer:
All of the above, it is not A
Explanation:
why do food chains in an ecosystem rarely contain more then five organisms
Why do food chains in an ecosystem rarely contain more than five organisms? ... Nutrients are lost from the ecosystem when organisms die. The conversion of food into growth by an organism is not very efficient. Energy is recycled by the decomposers back to the producers.
what are the steps for the respiratory system?
Answer:
Other components of the respiratory system conduct air to the lungs, such as the trachea (windpipe) which branches into smaller structures called bronchi. The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation).
Answer:
The primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe.The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled.In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs.Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed.Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the cycle begins again with the next breath.The diaphragm is a dome-shaped muscle below the lungs that controls breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs. Adults normally take 12 to 20 breaths per minute. Strenuous exercise drives the breath rate up to an average of 45 breaths per minute.
What happens to matter and energy in the process of photosynthesis?
Answer:
Matter movement: Carbon dioxide and water enter into the cell. Matter change: Carbon dioxide and water react resulting in glucose and oxygen. Energy change: The light energy of the sun is converted into chemical energy that is stored in the high energy C-C and C-H bonds of glucose.
