Parrotfish are herbivores that are found in coral reefs. To escape predation, a parrotfish will graze with a rabbitfish, which has venomous spines at the end of its pelvic fins. The rabbitfish does not benefit from this relationship. Which type of relationship do the parrotfish and the rabbitfish have in the coral-reef environment? (5 Points) [Control]Commensal [Control]Mutualistic [Control]Predator-prey [Control]Parasit
Answer:
Commensal
Explanation:
Hope this helps
The type of interaction between the parrotfish and rabbitfish in coral reefs is Commensal.
What is Species interaction?The population of one species interacts with the population of other species that live in the same locality is called species interactions.
Here, in this scenario parrotfish are grazing with rabbitfish in order to escape from predation. As rabbitfish have venomous spines at the end of their pelvic pins and protect the organisms of parrotfish from predators. In this interaction, parrotfish get the benefit to escape from predators and survive freely, while rabbit fish doesn't benefit from this interaction, this interaction is called Commensalism.
Therefore, the type of interaction between the parrotfish and rabbitfish in coral reefs is Commensal.

Why are there differences between cell types?
Answer:
There are many different types of cells. For example, in you there are blood cells and skin cells and bone cells and even bacteria. Here we have drawings of bacteria and animal cells. Can you tell which depicts various types of bacteria? However, all cells - whether from bacteria, human, or any other organism - will be one of two general types: prokaryotic or eukaryotic. In fact, all cells other than bacteria will be one type, and bacterial cells will be the other. And it all depends on how the cell stores its DNA.

Isaiah leaves one city at noon. He has to be at another city 186 km away at 3:00 PM. The speed limit the entire way is 65 km/h.
Can he arrive at the second city on time? Explain your reasoning using mathematical evidence.
He will arrive at the second city on time
Using the formula for calculating speed expressed as:
Distance = Speed * time
Given the following parameters
Speed = 65km/hrTime = 3 hours (from noon to 3PM)
Get the distance covered by Isaiah;
Distance = 65 * 3Distance = 195km > 186kmSince the distance covered by Isaiah is greater than the distance from one city to another city, hence he will arrive at the second city on time

Answer: Renewable is the word resource refers to a natural resource, a naturally occurring thing that is useful to humans, such as water, wood, or minerals. Renewable means that a supply of something can be replenished.
Nonrenewable is something that can not be used again
Explanation: I hope this helps :D
Answer:
Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods of time.
Explanation:
ex Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants)
ex. A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource. Fossil fuels such as oil, natural gas, and coal are examples of nonrenewable resources.
Where does the organic material in soil originate?
a. physical weathering
b. chemical weathering
C. decomposing plant and animal matter
d. the atmosphere
Answer:
C. decomposing plant and animal matter
Explanation: Trust me
Most of the organic materials come to the soil from decomposing plants and animal matter, so option C is correct regarding the statement. Microbes decompose dead organisms so that their nutrients go into the soil and are further used by others.
What is the role of decomposers in the ecosystem?Plants require water, carbon dioxide, minerals from the soil, and other resources to produce food in an ecosystem, and heterotrophs such as humans and animals such as goats take these resources from the plants. After these plant and animals die, microbes decay them and release nutrients into the soil, where they can be taken up by plants and other organisms, allowing nutrients to be recycled back into the ecosystem.
Different organic substances and molecules, such as carbon, nitrogen, etc., remain within the soil and further enter the atmosphere in different ways. The organic matter that present in the animal fecal matter enter to the soil too.
Hence Most of the organic materials in the soil come from decomposing plants and animal matter, so option C is correct.

Answer:
Water, sunlight and soil composition are examples of abiotic factors.
Explanation:
Abiotic factors are those found in the environment and are devoid of life, being chemical and physical factors that are part of an ecosystem.
Examples of abiotic factors are water, wind, soil and its components, the degree of humidity or temperature, and are capable of influencing environmental conditions and living beings or biotic factors.
Regarding the other options:
Abiotic factors and populations correspond to living beings —plants and animals, for example— different from abiotic factors.

If a plant of a maple tree has more chloroplasts than the leaf of a tomato plant, then
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, generally speaking, the higher the chloroplasts present in a plant, the higher the rate of photosynthesis that occurs in that plant. This is because chloroplasts are cellular organelles that serve as sites in which photosynthesis occur. They are found in green plants and green algae.
Photosynthesis is the process in which green plants produce there own food by absorbing sunlight from the atmosphere in the presence of carbon dioxide and water. Hence, it can also be said that an increase in the number of chloroplasts will lead to an increase in the amount of food produced by a plant (for itself).
From the description above, it can be said that the plant of a maple tree has a higher rate of photosynthesis and hence produced more food (for itself) than the leaf of a tomato plant.
Chloroplast also contain a green pigment called chlorophyll which is responsible for the green colour in green plants. Hence, an increase in the number of chloroplasts in a plant could indirectly imply greener plant. Hence, the plant of a maple tree could have greener leaf than the leaf of the tomato plant.
