Match each image with the life function the organism is performing. 1.reproduction
Lorico [155]

Answer:

1. Obtaining energy

2. responding to a stimulus

3. reproduction

4. excretion

Explanation:

1. All living organisms require energy for their life processes. This energy is derived from food. The food we eat contains biomolecules that store energy. The energy stored by these food molecules is released by a process called RESPIRATION. Image 1 shows a cat trying to obtain energy by feeding. The food will eventually be broken down to release energy.

2. Stimulus is any thing (whether internal or external) that causes a change in an organism. In image 2, a man is responding to a sudden change in his back, which is pain.

3. Reproduction is a characteristics of living organisms that involves the production of young ones. Image 3 depicts two cells undergoing fertilization (fusion of nuclei) to produce a new cell. In turn, the cell divides again to form two gametes. The cycle continues like that.

4. Excretion is the removal of waste products from a cell. According to Image 4, the cell allows a food particle in and releases the waste contents out of the cell.

Where do scientists obtain adult stem cells?<br> saliva<br> pancreas<br> skin<br> bone marrow
Alex17521 [72]
<span> Embryonic stem cell research is kind of a dead area now since there is no way to control the differentiation. Most research is being done on adult stem cells to help map and control the differentiation process.

Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.

You could do a much easier report by covering cloning of mice through stem-cell technology. It is happening and helping scientists understand diseases. </span>
