Which statement describes an atomic nucleus? - Brainly.com
An atomic nucleus is a positively charged core of an atom, containing protons and neutrons. The correct statement that describes an atomic nucleus is: An atomic nucleus contains most of the atom's mass.
[FREE] Where are proteins made in the cell? A. Nucleus B. Ribosomes C ...
Ribosomes can either be free-floating in the cytoplasm or associated with the rough endoplasmic reticulum (RER). The former synthesize proteins that are destined for the nucleus, chloroplasts, or mitochondria, while the latter primarily produces proteins that are secreted from the cell or integrated into the cell membrane.
[FREE] Which is a product of nuclear fusion? A. A nucleus that has a ...
A nucleus that has a greater mass number than the starting materials. This accurately reflects that the process of nuclear fusion results in a heavier nucleus being formed from lighter nuclei.
What is an atomic nucleus? - Brainly.com
The atomic nucleus is the central part of an atom, made up of protons and neutrons. It determines the element and plays a crucial role in atomic mass and stability. The number of protons in the nucleus is key to identifying the element on the periodic table.
Which argument best explains the charge of an atomic nucleus?
The atomic nucleus is positively charged because it is made up of protons, which have a positive charge. Neutrons are neutral and do not contribute to the nucleus's charge. Electrons are negatively charged but exist outside the nucleus and thus do not affect its overall charge.
What is the main difference between the plum pudding model and the ...
In contrast, the nucleus model visualizes the atom more like a small solar system, where the sun represents the dense nucleus, and the planets represent the electrons orbiting around it. Rutherford's gold foil experiment provided key evidence against the plum pudding model.
[FREE] Which of these does not have a nucleus? A. Salmonella B. Amoeba ...
Instead of a nucleus, their genetic material (DNA) is located in a region called the nucleoid, which is not membrane-bound. B. Amoeba - Amoebas are eukaryotic organisms, which means they do have a true nucleus that is enclosed within a membrane.
The atomic number of the isotope - Brainly.com
Therefore, the nucleus of the isotope 238U contains 92 protons and 146 neutrons. It's important to note that in a neutral atom, the number of electrons is equal to the number of protons. Hence, there would also be 92 electrons, but option B specifically asks about the nucleus only, which contains protons and neutrons, not electrons.
The diagram shows four different locations in an atom.
In scientific discussions about atomic structure, it is widely accepted that protons and neutrons reside in the nucleus and account for the majority of an atom's mass, while electrons, which are found outside the nucleus, contribute negligible mass compared to protons and neutrons.
Which of the following is found in all cells? - Brainly.com
Nucleus - This is also found in eukaryotic cells, serving as the control center of the cell. Ribosomes - These are the only organelles present in all cell types, including prokaryotic cells (such as bacteria) and eukaryotic cells.
