Answer:
The first box would be the pH will decrease, and the acidity will increase, and for the second box, the pH will increase, and the acidity will go down.
Explanation:
As the hydronium concentration increases, the pH decreases, and therefore if the hydromnium concentration decreases, the pH will increase. pH is sort of backwards, as the level increases, the acidity will go down, and as it decreases, the acidity will go up.
when the concentration decreases, the pH level increases, therefore causing it to become more basic/alkaline (acidity decreases)

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
Answers
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.

Which statement is true about oxygen and nutrient levels of rivers? TIMED TEST
Your answer:
Fast moving mountain streams which flow over rocks and waterfalls are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Fast moving mountain streams are high in nutrients. Organisms have adaptations to hold on in fast moving water, resulting in a large diversity organism.
Slow moving flood plain rivers are high in oxygen due to the amount of surface area of the water that is exposed to the air.
Slow moving flood plain rivers are low in nutrients. These rivers move too slow for plant growth and other organisms to survive.

Explanation:
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.
Answers
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.
What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?
Answers
Answer:
Please mark as brainliest!!!
Explanation:
Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.
It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.

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 )
Answers
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.

what are the steps for the respiratory system?
Answers
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?
Answers
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.

A food chain in an ecosystem flows from green algae, to freshwater snails, to small fish, and finally to large fish.
Answers
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.
The producers represent the second trophic level.
