HELP !! 5. If you were a paleontologist who studies fossils of very ancient life forms, where would be the best place to look for very old fossils: on land or in the oceans? 6. Imagine that Earth’s magnetic field was fixed in place and the polarity didn’t reverse. What effect would this have on our observations of seafloor basalts? 7. Look at a map of the Atlantic seafloor with magnetic polarity stripes and recreate the history of the Atlantic Ocean basin.
The best answer would be the lands. It is where you can easily dig up and locate old fossils rather in in oceans which needs much effort to do. Hope this helps. Have a nice day.

Active transport performs which function in a cell? A. packages proteins for export from the cell B. distributes enzymes throughout the cytoplasm C. moves substances against a concentration gradient D. equalizes the concentration of water inside and outside the cell
Active transport moves substances against the concentration gradient.
Because the transport it against the gradient, it required energy. Various nutrients like amino acids, monosaccharides like glucose, electrolytes like Na+ are absorbed into the blood from intestine by active transport mechanism only.
When the transport of molecules is along the gradient it is referred as passive transport. However some of the substances are absorbed with the help of a carrier ion or molecule. Such mechanism is called facilitated transport.

Why would skin cells divide faster than liver or kidney cells? Skin cells need more oxygen. Skin cells are smaller. Skin cells go through more wear and tear. Skin cells have extra DNA.
The body only produces what it needs. There is also a greater limitation when it comes to space within our bodies and in organs such as the liver and kidneys. Skin cells reside on the outside of our bodies and because if this, we tend to lose more of them compared to the cells inside our bodies. The epidermis is also the largest organ on our bodies, so cells are not as limited to space when compared to other organs.
A student exposed two plants to only red light and two plants to only green light. which plants should grow faster and why?

Express your opinion about whether or not either the human population or the economic wealth of humans should be a concern. Express your opinion about who should make decisions about how land is used for various human activities such as farming, industry, and recreation. What should be done if people disagree about how to use land? Express your opinion about the need for sustainable development strategies. Are they necessary or not? Explain your point of view. Give examples to support your viewpoint.
1) neither of them are a concern. Even if humans overpopulate the earth, the strong will find a way to survive and Darwin's theory of evolution will determine who deserves to pass on their genes and rule the world. This will result in stronger and stronger humans each generation. Economic wealth is not a concern for similar reasons. The strongest, smartest humans will pass on their genes and their wealth, thus ensuring that only strong, smart humans will survive.
2) People who own the land should decide what to do with it. If there is a disagreement, they can fight about it, and call all their relatives to come back them up in a fight. Whoever survives the fight gets to make the rules.
3)Sustainable develpment strategies are not necessary, becauase God has a plan. We can continue to burn oil, deplete the ozone, and drive giant SUVs because God will provide for us, and then eventually he will take those to heaven who deserve it and let the rest wallow in their hellish filth. >:-)
This is a fun question. Since it's an opinion, it can't be wrong, right? LOL

2) A) transport sugar
3) D) transports fluids throughout the plant.
4) A) epidermal cells

Xylem is a specialized tissue in vascular plants that is primarily responsible for the distribution of water and nutrients from roots to stems and leaves. The xylem also provides mechanical support and storage to the plant.
Phloem is a specialized tissue in vascular plants that is primarily responsible for the distribution of food nutrients such as glucose (sugar) and amino acids from the leaves to various parts of the plant
This element is found in all living things. It is recycled when organisms die. It is transformed from one form to another through photosynthesis and cellular respiration. That element is
Answer: The element is carbon element.
Carbon is the most versatile element on the planet. It is found in all the living things and is recycled when the living beings die.
This element in the form of carbon dioxide is utilized by the plants to synthesize glucose (in which this element is also present) that is used in the form of food for the plants. The reaction for photosynthesis follows the equation:
It is also released by animals in the form of carbon dioxide as a cellular respiration product.
Hence, the element is carbon.
Animals whose bodies do not have a certain shape are considered what? a.bilaterally symmetrical b.asymmetrical c.radially symmetrical d.unilateral
Which one of these is an example of cell division at work? a. A tree grows taller. b. A dog digests food. c. A muscle contracts. d. A plant dies.
The right option is; a. A tree grows tall
A tree grows tall is an example of cell division at work because growth is associated with cell division. Also, cell division in multicellular organisms such as plant involves tissue growth and maintenance. Cell division is a process of reproduction in which a cell divides into two or more cells. In this process, production of new cells involves DNA replication and there are various types of cell division. Prokaryotes (such as bacteria) divide their cell using binary fission, while eukaryotes divide their cell by mitosis or meiosis in some.
