Which of the following would be least likely to be part of an ionic bond?- calcium
- Carbon
- lithium
- Bromine

Answers

Answer 1
Answer:

Answer:

Carbon is least likely to be part of an ionic bond.

Explanation:

  • Ionic bond is formed by the process of transformation of electron between two atoms.
  • In ionic bonds the charges of cations and anions are balanced.
  • For the atom of carbon to form an ionic bond it must transfer 4 electron or gain 4 electron from another atom, this is not likely to occur in the chemical reaction.
  • Hence carbon atom shares 4 electron so that it can have the configuration of noble gas.

What cell don't have any membrane bound organelles but they do have a nucleus A. Dna
B. Prokaryotic
C. Nucleus

Answers

Prokaryotic cell don't have any membrane bound organelles but they do have a nucleus. Thus, the correct option is B.

What is prokaryotic cell?

Prokaryotic cells are defined as the cell which single-celled, non bound organelle microorganisms known to be the earliest on earth. Prokaryotes comprises bacteria and archaea.

The photosynthetic prokaryotes comprises cyanobacteria that perform photosynthesis. A prokaryotic cell comprises of a single membrane and hence, all the reactions occur within the cytoplasm. The below diagram shows a prokaryotic cell.

Neurons are the building blocks of the nervous system. They process and transmit signals. In a neuron, the nucleus is found inside the cellbody.

What is nervous system?

Neurons are the nervous system's fundamental structural and functional units. They are the most important components in the signal transmission process. Neuronal function is essential for the nervoussystem to function properly. The following are key components of neurons.

  • Dendrites- Dendrites are responsible for signalreception.
  • The nucleus and cytoplasm are found in the cell body, which is where the signal from dendrites is integrated. It is the cell's metabolic core.
  • Axon- The long-tailed structure of neurons that is myelinated in the CNS by oligodendrocytes and in the PNS by Schwann cells. It conveys the electrical impulse from the cell body to the outside world.
  • The knob-like structure at the end of the axon contains different neurotransmitters and VGIC (voltage-gated ion channels). They're in charge of converting electrical signals into chemical signals at the synapse.
  • The gap between twoneurons is known as a synapse. It is in charge of the signal's unidirectional travel.

Thus, we can conclude that in a neuron, the nucleusis found inside the cell body .

the nucleus is found inside the cell body (soma). around the cell body (soma) there are some roots which are the dendrites which is what brings electrical signal to the cell body (soma) and the axons take away information from the cell body
