Answer:
Open circulatory system
Explanation:
An open circulatory system, found in arthropods, pumps blood into a cavity called a hemocoel where it surrounds the organs and then returns to the heart(s) through ostia (openings). The blood found in arthropods, a mix of blood and interstitial fluid, is called hemolymph.Arthropods have an open circulatory system. In an open circulatory system, blood isn't transported in the body through veins and arteries; it flows freely within body cavities and makes direct contact with the organism's internal tissues and organs! Most arthropods that live in the water have gills.

Please I beg you help me. Compare solids,liquids, and gases on the molecular level
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Answer:
The compression of solids is difficult, liquids are nearly incompressible but gases can be easily compressed.
Explanation:
molecular arrangements of solids is regular and close, but liquids have irregular and sparse molecular arrangement. Gases too also have more random and sparse arrangements of molecules.
humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacteria than once killed how does the theory of evolution explain this antibiotic mutated the bacteria which allowed resistance develop
Answer:
Changes in genetic makeup occurs with the passage of time.
Explanation:
Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
What are the major sources of evidence for evolution how does each support the theory of evolution?
Answer:
DNA is one of the major sources might be wrong tho
Explanation:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Which two viral characteristics provide evidence to support the
argument that viruses are more similar to living components than to
nonliving components of an ecosystem?
Living Characteristics of Viruses Nonliving Characteristics of Viruses They reproduce at a fantastic rate but only in living host cells. They can mutate. They are acellular that is they contain no cytoplasm or cellular organelles. They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery.
If a molecule is to large or polar and cannot easily diffuse into the cell, it is
considered to be
to the membrane.
permeable
impermeable
hydrophilic
phospholipid
Answer:
hydrophilic
Explanation:
Large polar or ionic molecules, which are hydrophilic, cannot easily cross the phospholipid bilayer. Charged atoms or molecules of any size cannot cross the cell membrane via simple diffusion as the charges are repelled by the hydrophobic tails in the interior of the phospholipid bilayer.

why are vitamins important to enzymes and what this relationship is called?
The activity of some enzymes requires vitamins. This is because vitamin derivatives contribute to the biochemical mechanisms of these enzymes. These vitamin derivatives belong to a class of molecules known as cofactors, which are organic molecules (called coenzymes) or metallic ions, that assist in the catalytic activity of an enzyme.
Why do you think it would be important to know that both sides of the heart receive blood at the same time? Giving Brainliest
Explanation:
The right side of your heart receives blood from the body and pumps it to the lungs. The left side of the heart does the exact opposite: It receives blood from the lungs and pumps it out to the body. If your body didn't do it simultaneously, then blood would overflow your lungs.

Which of these energy transformations is taking place in the chimpmunk when its cells use the plants sugars to carry out cell processes?
Answer:
This question lacks options, the options are:
A. chemical energy -> kinetic energy
B. kinetic energy -> solar energy
C. solar energy -> chemical energy
D. kinetic energy -> nuclear energy
The correct answer is A.
Explanation:
All living organisms need energy to carry out certain processes in their body. This energy is obtained in form of ATP (chemical energy) when their food molecules is broken down via a process called CELLULAR RESPIRATION.
This chemical energy (ATP) is needed to perform cellular processes in the body. According to this question, a chipmunk (animal) will utilize the energy it derives (ATP) from breaking down plant sugars to carry out its cell processes. This means that it will transform CHEMICAL ENERGY → KINETIC ENERGY.
Note that, kinetic energy is the energy due to motion in the Chipmunk.
A specific location in America has closed down several fossil fuel units and set up geothermal plants. In your own words, explain how this would affect the economy of the location. (5 points)
Answer:
The economy of the location would be affected in the following ways:
1. Setting up geothermal plants would create more Jobs as expertise in various fields would be required to render their services.
2. Setting up geothermal plants would increase more revenue generation for the government in taxes.
3. Setting up geothermal plants would attract the development of the location as more people would tend to live there, there would also be improved road networks, housing, e.t.c.
4. Closing down fossil fuel units would eradicate environmental pollution in terms of oil spillage and stop the reduction that has been ravaging agricultural activities due to contamination of water bodies and land as a result of the fossil fuel.
Explanation:
Geothermal power plants are expensive but renewable sources of electricity that use steam or hot water pumped to the Earth's surface from beneath the earth's crust to spin a turbine producing electricity.

How does bursting of animal cells take place
Answer:
Swelling and bursting of cells is also known as lysing. This happens when the concentration of solutes inside the cell is greater than the concentration of solutes outside the cell. It has to do with diffusion and osmosis. A high solute concentration relates to a lower water concentration. Since molecules like to diffuse from areas of high concentration to areas of low concentration, water will rush into the cell where the water concentration is lower causing it to swell and lyse.
Explanation:
How is upwelling important for marine organisms?
Answer:
Because the deep water brought to the surface is often rich in nutrients, coastal upwelling supports the growth of seaweed and plankton. These, in turn, provide food for fish, marine mammals, and birds. Upwelling generates some of the world's most fertile ecosystems.
Explanation:
Answer:
Upwelling is very important for marine organisms because these nutrients fertilize surface waters, encouraging the growth of plant life. Upwelling plays an important role in the movement of marine animals.
