People struggled to believe that some of Hooke's images were real because they were so strange and remarkable! Hooke noticed tiny boxlike spaces in cork under his microscope, which he depicted and characterized as cells. Plant cells have been discovered by him!
Answer:
They face vary of things such as asexual reproduction
Explanation:
Answer:
It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.
We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.
We should give the awareness to the general public related to decrease the recreational fishing impact.
Commercial fishing must be ban until we reaches the sustainable level of fish.
There must be place international limits to every country related to limited number of fish they can take.
Answer:
In the n=1 energy level, the atom has 2 electrons
Explanation:
Electrons orbit the nucleus of an atom in multiple rings (energy levels). The first ring of the electron can only hold 2 electrons. After that, electrons are added to the second ring. Excluding the first ring, all other rings can hold a maximum of 8 electrons.
For example, Oxygen is an atom with 6 electrons. The first energy level contains 2 electrons, and the second energy level contains 4 electrons. The second energy level has room for up to 4 more electrons.
In your example of an atom with 15 electrons, there would be 2 electrons in the first ring, 8 electrons in the second ring, and 5 electrons in the third and final ring.
To summarize, all atoms have a first energy level containing 2 electrons, and all other energy levels can contain 8 electrons. This is true no matter the number of electrons.
