The model shows a carbon cycle in an ecosystem.
Which process decreases the amount of atmospheric carbon dioxide?
A animal respiration
B factory emissions
C photosynthesis
D plant respiration
Answer:
C. Photosynthesis
Explanation:
A. Animal Respiration increases the ammount of carbon dioxide because the animals are exhaling the carbon dioxide.
B. Factory Emissions release carbon dioxide because of the fossil fuels that are being burned.
D. Plant respiration increases the amount of carbon dioxide because, as much as they do take in carbon dioxide, they also release carbon dioxide.
C. Photosynthesis is the only available answer because the plants are turning the carbon dioxide into oxygen within the process.

Assume that one of the disinfectant/antiseptics tested using the disc method had a clear zone of inhibition and to your surprise, you discover minute growth near the disc. What would explain this phenomenon
The presence of the minute growth near the disc signifies that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances.
What are zones of inhibition?The sensitivity testing in a microbiology laboratory is done to determine the effect of antibiotics on various bacteria organisms
The zone of inhibition when a disk method is used signifies the area of media where bacteria are unable to grow, due to presence of a drug that impedes their growth.
If there are presence of minute growth near the disc, it means that the bacterial innoculum contains mutant microorganisms that are able to grow in the presence of toxic substances such as disinfectants.
If these mutant bacteria organisms are not cleared by the disk method, it means that they cannot be killed by the disinfectant/antiseptics that is being tested.

A situation where the bones are connected exclusively by ligaments, cords, or bands of fibrous tissue is a ________. gomphosis syndesmosis suture synchondrosis
Gomphoses are fibrous joints whose bones are joined by fibrous tissue, ligaments, cords, or bands.
What is gomphosis?They are unions that are verified by multiple collagen fibers, which extend between the two joint surfaces and constitute the periodontium.
These joints without mobility, characterized by the presence of fibrous tissue, are the articulation of the dental roots with the alveolar cavity in which they are housed.
Therefore, we can conclude that gomphoses are fibrous joints whose bones are joined by fibrous tissue, ligaments, cords, or bands..

During the process of protein synthesis, which could cause the wrong amino acids to bond together and form an incorrect protein?
Answer:
missense mutation
Explanation:
What happens when the wrong amino acid is placed during protein synthesis? A missense mutation is a mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.

A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of _______ energy for the stream ecosystem
A leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem
Flow of energy in the food chainMost of the energy that enters an ecosystem comes from solar radiation. The producing organisms that carry out photosynthesis absorb solar energy and fix it in chemical energy. When consumers feed on producers, part of that energy goes to these organisms, which, by serving as food for other living beings, also pass on part of their energy to them. This, therefore, flows, in a unidirectional direction, passing from a lower level to a higher one.
With this information, we can conclude that a leaf from a deciduous forest that falls into a large stream and is consumed by insects would be a source of primary energy for the stream ecosystem

Explain how an adaptation can enable an organism to survive a long-term environmental change. Describe and example to support your answer
Answer:
survival of the fittest
Some die, some survive. Those that survive to reproduce pass along their genes. Some survive by good luck. Others survive because they happen to have some quality that gives them a better chance to tolerate the environmental changes. Assuming those qualities are heritable, they’ll become more common in the genes of the surviving population. Eventually they’ll predominate. The population will have adapted to the changes.
With the exception of very primitive organisms, living animals have various senses including those familiar to us as sight, sound, touch, taste, and smell. Certain organisms have senses that we do not share. For instance, the class of snakes we call “pit vipers” have a specific organ that senses heat from prey animals, even in total darkness.
Bats use echolocation, bouncing high-pitched sound waves off of obstacles and prey alike. So do dolphins.
Many insects have the ability to smell only a few molecules of pheromones from potential mate
I took the question differently than everyone else, but it sounded to me like the OP was asking for examples of HOW organisms adapt, not two organisms that adapted.
Adaptation often begins with environmental monitoring systems. Lets say antibiotics are taken by a patient and a small amount gets in the area of a pathogen who is testing its environment. The pathogen detects the threat and begins to construct a genomic edit that can counter it. Unfortunately for us, cells are still more skilled with biochemistry than humans.
If you mean like to adapt in an instant, we humans release adrenaline to overcome stress and it actually makes us more prone to overcome stress. Another example its σ32 is the heat shock sigma factor in Escherichia coli, which it helps the bacteria to survive in a “heat shock”.
When we look at evolution, we often look at bacteria or animals that aren't really related to us, like the dinosaurs and how they evolved into avian animals.
There are two examples in human history that are great for this question.
Humans
Yup. People have made adaptations to the environment. Well, at least the environment that we create for ourselves.
