- 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
- [FREE] During protein synthesis, mRNA is transcribed in the A. nucleus . . .
Understanding Protein Synthesis During protein synthesis, mRNA is transcribed in the nucleus of eukaryotic cells This process occurs when the genetic information in DNA is copied to form messenger RNA (mRNA), which will then carry this information to the sites of protein synthesis After transcription, the mRNA exits the nucleus and enters the cytoplasm, where proteins are built by ribosomes
- Which cell components are found in BOTH plant and animal cells?
Nucleus: The nucleus is present in both plant and animal cells It acts as the control center, housing the cell's DNA and managing processes like growth and reproduction Golgi Body (Apparatus): Also found in both plant and animal cells, the Golgi apparatus modifies, sorts, and packages proteins and lipids for storage or transport out of the cell
- The diagram below shows some subatomic particles.
In the context of the diagram described, it shows quarks and their relation to larger particles The large outer circle labeled 'X' most likely represents a nucleus, which is the center of an atom where protons and neutrons are located Understanding the Nucleus: The nucleus is composed of protons (which have a positive charge) and neutrons (which have no charge) Distinction Between Particles
- Which statement accurately describes the structure of the atom?
The structure of an atom consists of protons and neutrons in the nucleus, with electrons orbiting around the nucleus This arrangement highlights the atom's mass distribution and charge interactions Therefore, the correct statement is that protons and neutrons are in the nucleus while electrons are in the surrounding space
- [FREE] Which cell structures are seen in prokaryotic and eukaryotic . . .
In contrast, human cells are eukaryotic and contain organelles such as mitochondria and a nucleus that organizes their DNA The information about cell structures is widely supported by cellular biology literature, which outlines the fundamental differences and similarities between prokaryotic and eukaryotic cells
- [FREE] Select all the following that are present in a eukaryotic cell . . .
Eukaryotic cells possess features such as a nucleus, internal compartments, and mitochondria, which are not present in prokaryotic cells Both types of cells do have a plasma membrane, but it is the organized structure of eukaryotic cells that distinguishes them Therefore, the correct selections are the nucleus, internal compartments, and mitochondria
