When was a control used in the investigation of the amphipods and sea butterflies? Why was a control necessary?
pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from their voracious predators.
Why was progress in science interrupted during the dark ages? The Roman Empire fell in the 5th century thus advancements in science came to a halt. As science halted in Europe, where else did it advance? Science advanced in other areas of the world like China, Polynesia, and Arab nations.
what are the small pores called where carbon dioxide come in
Answer:
Stomata
Explanation:
These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed.

which microscope would be best to look at the wings of two different butterflies to determine which is a monarch butterfly and which is a viceroy butterfly?
To determine the difference between a monarch butterfly and a viceroy butterfly, it would be best to use a microscope that has high magnification and resolution, such as a compound light microscope or an electron microscope.
What is a microscope?A microscope is an optical instrument that is used to magnify small objects or details, such as cells or tissues, so that they can be studied or observed more closely. There are various types of microscopes available, including compound light microscopes, scanning electron microscopes, and transmission electron microscopes, which use different principles to produce magnified images of the objects being examined.
A compound light microscope would allow you to see the structures of the wings in detail, while an electron microscope would provide even higher resolution images, but would require the wings to be coated in a thin layer of gold or other metal in order to be viewed. Both of these types of microscopes would allow you to see the fine details of the wings and compare them to determine which is a monarch butterfly and which is a viceroy butterfly.

2. What are the two major subdivisions of the nervous system, and what does each division do?
Answer:
2 Major Subdivisions:
Central Nervous System
Peripheral Nervous System
Explanation:
The central nervous system (CNS) regulates the majority of bodily and mental activities. It is divided into two parts: the brain and the spinal cord. The brain is the core of our ideas, the translator of our surroundings, and the source of control over physical action.
The PNS is the nerve that links the CNS to the rest of the body. The peripheral nervous system's principal job is to link the brain and spinal cord to the rest of the body and the outside world. The peripheral nervous system sends and receives information to and from the central nervous system. This is done by neurons that convey information from sensory receptors in the eyes, ears, skin, nose, and tongue, as well as stretch receptors and nociceptors in muscles, glands, and other internal organs.

Answer the following question number 13 for 20 point
Answer:
All i could fine is metamorphic rocks
Explanation:
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.
Hoped that helped:P
Answer:
D, or hornfels.
Explanation:
Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism. It's not like animal metamorphism.

the 5 physical factors that scientists use to develop ocean and seafloor
zones are
1
2
3
4
5
Answer:
1. Light penetration
2. Distance from shore
3. Depth of water
4. Temperature
5. Amount of nutrients/salt
Explanation:
Oceanographers use various methods to determine vertical and horizontal zones in the ocean. First and foremost are the distance from the land and the depth of the water. These contribute to the other factors, such as temperature and light penetration. They also measure how much salt or nutrients are available at that zone, which plays a role in how much life is discovered in the location.
The photic and mesopelagic zones are mainly grouped by light penetration, while mesopelagic, abyssopelagic, hadalpelagic, benthic, and bathyal zone are categorized by depth and temperature. When looking at the pelagic zone, the neritic and the oceanic sections are differentiated by the distance from the land.

what part does chlorophyll play in photosynthesis?
Answer:
Explanation:
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar

Summary about DNA , Genes , Traits , Chromosomes. (Explain & let me know about all 4 words. Summarize all these words.) Write about how all 4 things work together.
Answer:
Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus. And a trait is a gene-determined characteristic.
DNA ___________ is important because it ensures that when a cell divides, the two resulting cells have the same genetic code. Pleaseee help
Answer: Replication
Explanation: When the cell is preparing to divide it will replicate its DNA so that both of the daughter cells will have a complete set of the DNA. It's like a book of instructions and the cell has to perfectly replicate it so that when it splits into two both of the new cells will have a perfectly made copy of it! Hope this helps :)
Gel electrophoresis allows molecules to migrate along the gel at different rates by using:
Answer:
Agarose gel or Pores in the gel
Explanation:
This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.
So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.

what is the main product or purpose of photosynthesis?
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

best explanation of the role of dna and rna in making proteins?
Answer:
DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.
DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.
What is protein synthesis?
Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously. The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription.
Initiation, elongation, and termination are its three stages. Following processing, the mRNA transports the instructions to a ribosome in the cytoplasm.
The ribosome, which is made up of proteins and rRNA, is where translation happens. The mRNA's instructions are read during translation, and tRNA then transports the appropriate sequence of amino acids to the ribosome. rRNA then facilitates the formation of bonds between the amino acids, resulting in a polypeptide chain.
A polypeptide chain may be further processed to create the finished protein after it has been created.
Therefore, DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

How is the flow of energy within food webs interconnected with the cycling of
matter?
Answer:
Dead producers and consumers and their waste products provide matter and energy to decomposers. Decomposers transform matter back into inorganic forms that can be recycled within the ecosystem. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat.
