PLZ HELP
cells and neutrons different
Well, neutrons are normally found with protons in the nucleus of an atom unless hydrogen unless deuterium
Neurons contain DNA.
red blood cells do not.
What is the function of a nerve cell in a multicellular organism?
carry and transmit signals
How are red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism?
They are small because they lack a nucleus.
7th grade Connexus student here are 2 of the answers.
What is the function of a nerve cell in a multicellular organism? ----- carry and transmit signals
How are red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism? ---- they are small because they lack nucleus
How do dendrites help the function of nerve cells ---- They help the neuron receive messages from the axon of another neuron
How might a red blood cell work with a neuron to support the function of a multicellular organism? ---- A neuron may signal when and where oxygen is needed.
How are red blood cells and neurons different? ---- Neurons contain DNA, but red blood cells do not.
I am gonna end it all
How is a neuron like and different from a blood cell?
ok
ok (yes I am schizophrenic)
yeahhh
To determine the differences between red blood cells and neurons, we can analyze each answer choice:
A. Neurons need oxygen, but red blood cells do not.
To determine if this statement is correct, we need to understand the role of oxygen for both red blood cells and neurons. Red blood cells are responsible for carrying oxygen to various tissues and cells in the body. They contain a molecule called hemoglobin that binds to oxygen. On the other hand, neurons are specialized cells involved in transmitting signals in the nervous system. While neurons require oxygen to function properly, red blood cells play a crucial role in delivering oxygen. Therefore, this statement is incorrect.
B. Neurons lack organelles, but red blood cells have organelles.
To evaluate this statement, we need to understand the structure and composition of both neurons and red blood cells. Neurons, being complex cells, contain various organelles such as a nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus, among others. These organelles are essential for the functioning of neurons. In contrast, red blood cells lack a nucleus and other organelles to make space for hemoglobin. Therefore, this statement is incorrect.
C. Neurons contain DNA, but red blood cells do not.
To ascertain if this statement is correct, we can compare the genetic material present in neurons and red blood cells. Neurons, like most cells in the body, contain DNA, which carries the genetic information necessary for cell function and development. Red blood cells, however, do not contain a nucleus and therefore lack DNA. Instead, they rely on the genetic information from the precursor cells in the bone marrow. Hence, this statement is correct.
D. Neurons are all the same size, but red blood cells are different sizes.
To determine the accuracy of this statement, we need to consider the size variations of neurons and red blood cells. Neurons can differ in size and shape based on their location and function in the nervous system. Some neurons can be quite long, extending from the spinal cord to the toes, while others are shorter. In contrast, red blood cells are typically a uniform size and shape, with an average diameter of about 7-8 micrometers. Therefore, this statement is incorrect.
Based on the analysis above, the correct answer is C. Neurons contain DNA, but red blood cells do not.
