Answer:
actively pump water back into their cells to counter its loss due to osmosis
Explanation:
- When an organism actively regulates the osmotic pressure of the bodily fluids present in the body in order to maintain homeostasis in the body then this is termed as osmoregulation.
- Since, the Great salt lake in Utah has a lot of salt in it, the water content in the surroundings of the brine shrimp is much less and hence, the water will move out of the brine shrimp's body as osmosis causes the movement of the water from higher concentration of water to lower concentration of water.
- However, movement of water out from shrimp's body would cause it to desiccate and hence, it must have an actively pumping system that pumps the water back into their cells in order to compensate for the water lost due to osmosis.
Answer: The correct option is D.
All of the above.
Explanation:
This is because complex organisms developed from cyanobacteria and release of oxygen. Cyanobacteria is a blue green algae and first organism that photosynthesized. It uses carbondioxide and water in the presence of the chlorophyll present and light energy to produce carbohydrates and oxygen. The oxygen released into the atmosphere brought about respiration and development of ozone.
This great oxidation event changed the Earth and life on Earth too.
The range of ratio which can be used to indicate that a gene was not expressed in the cancerous tissue but was expressed in the healthy tissue is 0.5 - 0.0625.
Microarray is a technique that is used to measure the differences between the cancer cells and the normal cells. The method measures the amount of mRNA for genes that are present in a sample and compare the results between healthy and cancerous cells. A value of less than 1 indicates that the genes from the microarray are more active in normal cells.
<h3><u>Answer;</u></h3>
Nodes of Ranvier
<h3><u>Explanation;</u></h3>
- Nodes of Ranvier are the spaces between the myelin coating on the neuron's axon.
- Nodes of Ranvier have space exposed to conduct electricity with the environment to propagate the signal down the axon.
- At the nodes of Ranvier, electricity can be conducted within the cell's environment, and the electrical signal will be propagated down the axon.
