Answer:
Due to no jaws, no paired fins and scales on the body.
Explanation:
Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.
How is the earthworm limited by being a skin breather?
Answer:
Earthworms need oxygen just like humans, but they don't have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. ... This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration).

Some sugar that's made is usually take and unhealthy, but other sources can be purely made with no artificial s added to it making it fake.
How does the size of a bacterial cell compare with an animal cell?
Answer:
hope it helped
Explanation:
Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.

Which is not a likely economic tool to address environmental issues?
Emissions fees and taxes
Responsibility for a product from production to disposal
Small business liability relief
Defunding government regulation
Explanation:
Policy-makers have two broad types of instruments available for changing consumption and production habits in society. They can use traditional regulatory approaches (sometimes referred to as command-and-control approaches) that set specific standards across polluters, or they can use economic incentive or market-based policies that rely on market forces to correct for producer and consumer behavior. Incentives are extensively discussed in several EPA reports
Two basic types of traditional regulatory approaches exist. The first, a technology or design standard, mandates specific control technologies or production processes that polluters must use to meet an emissions standard. The second, a performance-based standard, also requires that polluters meet an emissions standard, but allows the polluters to choose any available method to meet that standard. Performance-based standards that are technology-based, for example, do not specify a particular technology, but rather consider what available and affordable technologies can achieve when establishing a limit on emissions. At times, EPA may completely ban or phase out the use or production of a particular product or pollutant, as it has done with chlorofluorocarbons (CFCs) and certain pesticides. Regulations can be uniform or can vary according to size of the polluting entity, production processes, or similar factors. Regulations are often tailored in this manner so that similar regulated entities are treated equally. MARK AS BRAINLIEST IF IT HELPS

3. Explain how the Gulf Stream (a warm ocean current) effects the climate of Northern Europe.
Answer:
These currents transfer heat from the tropics to the polar regions, influencing local and global climate..
The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about 150 times more water than the Amazon River. The current moves along the U.S. East Coast across the Atlantic Ocean towards Europe ...The heat from the Gulf Stream keeps much of Northern Europe significantly warmer than other places equally as far north.
Answer:
The Gulf Stream, located in the north Atlantic Ocean, has an important effect on climate, transportation by sea, and the circulation of nutrients and waste in the ocean. It works together with the North Atlantic Drift to bring warm air from equatorial regions across Europe. This changes Europe’s climate by providing mild temperatures and more rain. As a result, farmers can grow more crops, and fewer freezing temperatures damage goods.

Which pair of structures would provide a positive identification of an animal cell under a microscope?
flagellum, lysosome
nucleus, mitochondrion
ribosome, cell wall
chromatin, chloroplast
flagellum, lysosome: Both of these are found in animal cells, but the real difference is flagellum is ONLY found in animal cells
nucleus, mitochondrion: Both of these are found in Animal cells X
ribosome, cell wall: Cell wall is only in plants X
chromatin, chloroplast: Chloroplast is only found in plant cells X
Explanation:
Firstly cell wall and chloroplasts can only be found in plant cells and will not appear in an animal cell.
Flagellum usually appears in many bacteria (microorganism) and only a few animal cells. Most animal cells do not have flagellum.
However animal cells do have a nucleus which contains important genetic material such as DNA and mitochondrion which creates energy for the cell to use for metabolism inside the cell. (Even though most eukaryote cells have these 2 organelles)
Between the 1st and 2nd options, none of them is exactly correct. But nucleus and mitochondria are more widely found in various types of cells (plants, etc.)
I would choose the 1st option as the best answer here because it is more detailed.
1. Name the two major divisions of the nervous system; list the organs/tissues found in each.
2. Name the two divisions of the peripheral nervous system (PNS), and give the primary function of each.
3. List at least seven stimuli that would trigger sensory receptors.
4a) Choose one stimulus from Q. 3, and describe in a complete sentence how the stimulus would travel to the central nervous system (CNS).
4b) Describe in 1-2 complete sentences how the motor commands from the CNS would travel to the effector target organ or tissue. Tell if the motor command will travel via the somatic or autonomic nervous system; explain why.
2
5. Choose another stimulus from Q. 3 that will initiate a CNS motor response that will travel via the other motor division (SNS/ANS) of the peripheral nervous system (PNS) described in Q. 5. Explain your reasoning.
Answer:
1.Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else.
2.Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.
3.Sensory receptors with corresponding stimuli to which they respond.
Receptor Stimulus
Apmullae of Lorenzini (primarily function as electroreceptors) Electric fields, salinity, and temperature
Baroreceptors Pressure in blood vessels
Chemo receptors Chemical stimuli
Electromagnetic radiation receptors Electromagnetic radiation
Electroreceptors Electrofields
Hydroreceptors Humidity
Infrared receptors Infrared radiation
Magnetoreceptors Magnetic fields
Mechanoreceptors Mechanical stress or strain
Nociceptors Damage or threat of damage to body tissues (leads to pain perception)
Osmoreceptors Osmolarity of fluids
Photoreceptors Visible light
Proprioceptors Sense of position
Thermoreceptors Temperature
Ultraviolet receptors Ultraviolet radiation

DNA:
DNA, also known as deoxyribonucleic acid, is the nucleic acid responsible for storing the genetic material of the cell. The DNA is found in the nucleus of eukaryotic cells or in the cytoplasm of prokaryotic cells. The DNA molecule produces proteins via the process of gene expression. The proteins, which acts as enzyme and hormone, controls cellular processes. Therefore, the conclusion about DNA from the idea that it is a cell's "brain” is that it controls what cells do.Learn more at: https://brainly.com/question/19365715?referrer=searchResults
