B.
vessels
C. companion cells
Answer: The correct answer is- C) Companion cells.
Phloem tissue is a complex conducting tissue that is present in the vascular plants and responsible for the transport of organic compound such as carbohydrates and proteins from leaves to the rest part of the plant.
The various components of phloem tissue are- Sieve element, Companion cells, phloem parenchyma, phloem fiber.
Companion cells are specialized cells ( present in association of sieve element) that perform various metabolic reactions and responsible for cellular activities. They help in loading and unloading of carbohydrate into sieve element.
Answer:. Biotic limiting factors:
- Alligator: The presence of alligators in the simulation acts as a biotic limiting factor. Alligators are known predators of cricket frogs and can feed on them, thus reducing the cricket frog population.
- Mosquito: Mosquitoes are also considered a biotic limiting factor. They can potentially transmit diseases to cricket frogs or compete with them for resources, affecting their population.
2. Abiotic limiting factors:
- Food: In the lab simulation, food availability serves as an abiotic limiting factor. If cricket frogs do not have access to an adequate food supply, their survival and population growth can be negatively impacted.
- Pollution: Pollution, another abiotic limiting factor, can have detrimental effects on the cricket frog population. Pollution in the air or water can lead to habitat degradation, decreased water quality, and ultimately affect the survival and reproductive capabilities of the frogs.
3. Limiting factor impacting the cricket frog population the most:
- The predator population (alligator): Based on the evidence provided, the alligator population had the greatest impact on the cricket frog population. Alligators are known to be predators of cricket frogs, and their presence in the simulation likely resulted in significant predation and reduction of the cricket frog population.
4. Limiting factor impacting the cricket frog population the least:
- Pollution: From the information given, pollution is identified as an abiotic limiting factor. While pollution can negatively affect the cricket frog population, the evidence provided suggests that the predator population (alligators) had a more significant impact. Therefore, pollution is considered to have impacted the cricket frog population the least.
Explanation:
Operant Conditioning is the process by which clinicians identify the stimuli that lead to pain behaviors and the reinforcers that follow, thereby enabling the development of relevant strategies for pain management.
The process of identifying the events (stimuli) that precede pain behaviors (responses) as well as the consequences that follow (reinforcers) in pain management is called Operant Conditioning. This principle of behavioral psychology, which holds that our behaviors are motivated by the consequences they produce, is often used in behavioral therapy for chronic pain management. By understanding the stimuli that lead to pain behaviors and the consequences that reinforce them, clinicians can help patients develop strategies to mitigate their pain.

Explanation:
A peer review is a process of analysis of the research product by the person other than the one who has conducted the research. Such a person exhibit knowledge of the subject or topic in which the research has been conducted. The reviewer reads the written document related to the research, rectifies the mistakes and gives opinion for the betterment of the research outcome.
