Answer: a) relies on the uptake of an external signal molecule from the cell
Explanation: Signal transduction is known as the transmitting of any signal of a molecule from exterior of cell to interior of cell.This technique is termed as critical is taken care of successful transmission of signal effectively and positive result and reception is done by the cell surface receptors.It is also known as cell signalling. Thus,option(a) is the correct option of all.
Answer: True because In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
Answer:
This is technology.
Explanation:
Generally both science and technology are instrumental to emergence of developed humanity and the environment.Why science is concerned with the emergence of knowledge,the manoeuvre and the practical application of the knowledge for innovations to change and improve the world around is called Technology.
The application of technology for improvement of humanity has wide application.From Healthcare in genetic engineering,Biomedical sciences, telemedcine,robotic surgery,to Agriculture to boost food production,cloning of crops and animals and production of pest and herbicide resistant products.
In construction for roads,and building of houses,fitted with AC and FAN for maximum comfort
Besides the application in field of engineering for power generation in petroleum, communication, entertainment,printing,warfare and transportation are few of other means where technology has improved humanity
<span><em>Whether living or non living:</em>
<em>When you put a sample of tissue under a microscope, if u can see a cell membrane, and can identify some cell structures like nucleus, mitochondria, vacuoles etc. , it was living, if not, its a non living thing.</em></span>
<span><em>However some cells don't have a nucleus( eg. prokaryotic cells), but all cells have a cell membrane or some sort of protective covering to contain the cell's insides. </em></span>
<span><em>To check if your specimen maybe-once living, maybe-still living "something", is living, get a look at it through an electron microscope - thats the best microscope ever- and see if the mitochondria's making any ATP( adenosine triphosphate, source of energy for most organisms), if it does, its living. If not, no</em></span><em>n living. :)</em>
Idk but some people prefer Starbucks as it tastes better
