<u>Answer:</u>
<em>C. many more generations can be studied using short-lived organisms</em>
<u>Explanation:</u>
<em>Fruit flies are organisms with a shorter lifespan.</em> Their average lifecycle takes about a week to develop from lava to an adult. This <em>characteristic of fruit flies are reason they are used for the genetic investigation. </em>
The <em>genetic characteristics of the organism</em> can be studied over a short time. The accuracy of the study can be increased as there will be more <em>data and statistics related to same experiment. </em>
<em>Long term effect as well as short term effect can be studied easily. </em>
Answer: Signal Transduction
Explanation: A biochemical cascade, also known as a signaling cascade or signaling pathway, is a series of chemical reactions that occur within a biological cell when initiated by a stimulus. This occurs in the second step of cell signaling.
Answer:
natural disasters,emigration and scarcity of food
Explanation: natural disasters: this affect population where by organisms leave there area or habitat for another area due to unfavorable conditions eg. flood, bush fire, storms, earthquake etc. and can also lead to death.
Emigration:this is when organisms leave an area for another either in search of food, breeding purpose this reduses population where by organisms may never return.
scarcity of food:this occur when there is insufficiency or no food in an area which makes organisms leave their habitat for another in search of food and might even lead to death.
Hey there
the answer is
a Archean is a single celled microorganism and has no cell nucleus
and Bacteria <span>constitute a large </span>domain<span> of </span>prokaryotic microorganisms<span>. Typically a few </span>micrometres<span> in length, bacteria have a </span>number of shapes<span>, ranging from </span>spheres<span> to </span>rods<span> and </span><span>spirals</span>
so im going to say D as the answer
Hopes this helps u :)
