Which of the following is a accurate depiction of primary ecological succession?
Answer:
This question lacks options, however, primary succession will be explained for detailed comprehension.
Explanation:
Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.
Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.

What are the similarities and differences between predation and parasitism
plz answer
Answer: Predation Parasitism
Larger and stronger than the prey. Smaller than the host organism.
Metabolic Dependency
There is no such metabolic dependency between the predator and a prey. There is an intimate association involving metabolic dependency on the host.
Progression
Explanation:
A parasite obtains food and shelter from the host whereas a Predator will catch and kill its prey.
An ecosystem has been interrupted by an invasive species. A new grass eating lizard lives in the same ecosystem as a grass eating rabbit. Hawks eat both lizards and rabbits. What would happen to the grass and hawk populations immediately? Why?
There would be more hawks appearing because there is more food (both lizards and rabbits) and grass would lessen because there is another source feeding off of it.
I hope this helped ^^
Answer:
the grass population would decrease and hawk population would increase
Explanation:
what are the different ways fungal spores can be dispersed?
Answer:
Explanation:
The spores of some fungi are dispersed in water or on the surface of water. The chemical composition of the wall of these spores makes them "non-wettable" so they won't sink. The spores are carried along on the surface of the water like little boats. Water in the form of raindrops can disperse spores in a different way. While gravity is not a primary means of spore dispersal, evolutionary adaptations have been required of many fungi to overcome gravitational effects for effective spore dispersal. SPORE DISPERSAL BY WIND Dispersal of fungal spores by wind is by far the most common method for terrestrial fungi.

Which situations would be most likely to engage the anterior cingulate cortex?
Answer:
Which of the following situations would be most likely to engage the anterior cingulate cortex?
A waiter walks over to your table at a restaurant and holds an open menu in front of you.
You walk into the elevator of your apartment building and press the button for your floor.
You enter your classroom and find someone sitting in your usual seat.
A good friend asks you to remind him of your telephone number.
Explanation:
In order to meet the demand of the surrounding environment by adjusting the motor outputs from the brain to the environments ,a part of the emotion control part of the brain( limbic system) called the anterior cingulate cortex is responsible for this.
Anatomically, the limbic system is made up of the primarily the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia and cingulate gyrus.
Based on the this its(anterior cingulate cortex) functions are formation of emotion in the limbic system, and possessing of memory and learning.
it is also a major parts of of pain networks for pain modulation and perception.
Therefore whenever there is change in the environment from the prestored condition in the brain,(e.g the usual seat in the class room occupied above) the anterior cingulate cortex adjust the motor input from the brain to adapt to the new environment to take an action,whih in this case leads to the reclaiming of the seat or any other necessary proactive action.

Answer the following using directional terms specific to the dentition. a Your canine is _______________________________________ relative to your first molar. b Your third molar is __________________________________ relative to your second molar. c The cheek side of the tooth row is the ______________________________ side. d Your lateral incisors are _________________ relative to your central incisors. e The tongue side of the tooth row is the ____________________________________ side. f Where your opposite tooth rows meet (to chew) is the _______________________________ surface.
Answer:
The correct answer is - a. mesial, b. distal c. buccal d. distal e. lingual f. occlusal.
Explanation:
Mesial is the surface near the midline of the face, In dentistry, the canine is mesial to the first molar which means it is the middle of the face. The third molar is distal to the second molar.
Distal is the backside of a particular tooth in dentistry. The cheek side of the tooth known as the facial surface for the front teeth in dentistry. Lateral incisors are distal to the central incisors. Lingual is the part of the tooth near the tongue. The chewing surface of posterior teeth is also known as the occlusal.
When it was time to go outdoors, 3-year-old Casandra said she didn’t want to play and headed for her locker. At the teacher’s gentle insistence, Casandra reluctantly joined the other children on the playground. Tears rolled down her cheeks when the teacher boosted Casandra onto a swing seat and began to push her. The teacher stopped the swing and helped Casandra off. She held her closely for a few minutes and then asked why she was crying. Casandra initially denied that anything was wrong. However, when the teacher persisted, said she "had fallen the night before and hurt her bottom."
The teacher took Casandra inside and asked to see where she had been hurt. When Casandra pulled down her shorts, the teacher noted what appeared to be a large burn with blisters approximately 2 inches in length by 1 inch in width on her left buttock. Several small bruises were also evident along one side of the burn. Again, the teacher quietly asked Casandra how she had been hurt, and once again she replied that she "had fallen."
What actions should Casandra’s teacher take?
Answer:
casandra was scared around others
Explanation:
in the passage i notesed that she went to her locker and started crying
Answer: 1. Casandra's teacher should take her to the nurse and just tell the nurse that she got hurt in the playground 2. The teacher should gather more evidence until she knows that something is going on because she can't prove that something is really happening 3. She shouldn't tell the parent yet because they would probably accuse the teacher of doing it 4. If it was the first time , I would feel bad for the girl and just tell her to be careful but if it kept happening, I would tell the principal and her parents and I would feel angry

Indoor air pollutants can be dangerous because the air pollutants stay in small space rather than circulating throughout the atmosphere. Which of these choices is an example of an indoor air pollutant?
A. Methane gas
B. Vehicle exhaust
C. Building materials
D. Industrial emissions
Indoor air pollutants can be dangerous because the air pollutants stay in small space rather than circulating throughout the atmosphere. Option C is the correct answer.
What is the methane gas ?It is the gas that is produced by the cow dung and the gas is produced by the various chemical reactions in it.
Building materials pollution can be reduced out by many ways. Here are a few examples:
Low-VOC Paints: Volatile Organic Compounds (VOCs) are chemicals found in many paints, which can emit harmful fumes into the air for years after the paint has dried. Low-VOC paints contain fewer or no harmful chemicals, reducing indoor air pollution and improving air quality.
Air-Purifying Plants: Certain indoor plants, such as peace lilies, spider plants, and Boston ferns, can help remove harmful pollutants from the air. These plants absorb pollutants such as formaldehyde, benzene, and xylene, improving indoor air quality.
Green Roofs: Green roofs are roofs covered in vegetation that can help absorb pollutants from the air, reducing air pollution in urban areas. Green roofs also provide insulation, reducing energy costs, and can help mitigate the urban heat island effect.
Therefore ways like these should be adopted.
