Atoms are not changed in a reaction. They are just ____________________
Answer:
rearranged
Explanation:
Atoms are the most basic unit of matter that makes up elements. Atoms are made up of electrons orbiting a nucleus comprising protons and neutrons.
The atomic number, is defined as the number of protons in an atom, while the atomic mass, is the number of protons and neutrons.
In reaction, atoms are not created or destroyed, the atoms simply become rearranged in new formats; molecules are two or more atoms bonded together. Different molecules can join together to form compounds.
Because most nerve cells do not typically undergo mitosis, they are generally not capable of which of the following
Answer options:
producing enzymes generating more nerve cells performing cellular respiration transporting ions against a concentration gradientAnswer:
generating more nerve cells
Explanation:
Mitosis is a type of cell division that creates new cells for growth, regeneration, and repair of tissues in an organism.
The cells produced are identical daughter cells.
However, their inability to perform cell division does not affect their ability to perform other process like enzymes, respiration, and ion transport.

If blue crabs dropped out of the food chain, would you expect to see a decline in any other organisms of the Bay? which organisms?
Answer:
Any organism that eats the blue crab will decline.
Explanation:
If blue crabs dropped out of the food chain, I would expect to see a decline in eels, drums, spots, Atlantic croakers, striped bass, sea trout, and catfish because crabs are an important food source for these organisms. Some sharks, cownose rays, Kemp’s riddley, and loggerhead sea turtles also eat on blue crabs at different stages of life.

Which situation would affect an organism's niche in a positive way?
Answer:
hope it helps
Explanation:
Niche construction is the process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism's environment or encompass when an organism actively moves from one habitat to another to experience a different environment.
Abundant abiotic factors would affect an organism's niche in a positive way.
What is a niche?The functional role that an organism plays within an ecosystem is defined by its niche.The biotic variables, which include living features such as animals, plants, and fungus, as well as abiotic factors, influence the niche (also known as the "ecological niche"). Abiotic factors include non-living elements like sunshine, water availability, and weather, as well as resources like food and other nutrients.learn more about niche here:
