As you walk to your classes, your muscle cells are typically conducting _____.
Carbon dioxide concentrations in soil are ________ than (as) in the atmosphere because ________.
Do nerve cells, blood cells, and skin cells all have the same DNA? Explain Reasoning. Please help! :)
The DNA between nerve cells, blood cells, and skin cells would be because all of the cells in our bodies start from a single fertilized egg. As cells divide and grow, different genes are expressed, resulting in different cell types. Those cells then produce a variety of proteins specific to the cells they form resulting in most of our chemistry.
he _____ is the division of the autonomic nervous system associated with rest, repair, and energy storage. a. parasympathetic nervous system b. sympathetic nervous system c. somatic nervous system d. endocrine system
Answer: Option A) parasympathetic nervous system
The autonomic nervous system consists of two parts namely
- the sympathetic nervous system SNS, and
- the parasympathetic nervous system PNS
The PNS stimulates the same organs as SNS, but its action is opposite to SNS.
And it acts to return the body to a normal state, thus it is associated with actions such as:
- slowing heart beat
- dilates arteries,
- lowering blood pressure
- stimulating saliva secretion etc
All these actions of the PNS bring about rest, repair, and energy storage.
In an ecological pyramid, what happens to energy, biomass and number of species as you move up?
As you move up each trophic level energy decreases, trophic levels need energy to sustain it and hence it which means more resources, which decreases the number of organisms.
Organ of the endocrine system behind the stomach from the point where it crosses the portal vein to the point where it enters the splenorenal ligamnet
This would be the pancreas
Suggest a reason why the veins of a bodybuilder "pop out" more than a person who does not lift weights. why don't we see arteries "pop out"? 4. why do you think arteries, veins and nerves always travel together? provide an example that illustrates your reasoning.
an animal cell on the left and plant cell on the right which two cell parts are most likely found in both types of cells
Plant cells and animal cells are both eukaryotic hence, they have many similar organelles. Common organelles are:
Cell membrane: the structure that separates a cell from exterior environment.
Nucleus: structure where hereditary material is present.
Ribosome: structure where proteins are made.
Endoplasmic Reticulum: associate in protein production
Golgi complex: structure where proteins are modified and packaged.
Vacuole: acts as a storage house for a cell
Cytoplasm: fluid in which all the organelles float.
