The main difference between a prokaryotic cell and a eukaryotic cell is that the prokaryotic cell have no true nucleus instead its genetic material is just suspended in its cytoplasm termed as nucleoid. The nucleus when viewed under the microscope is a membrane bound which is easily distingushable compared to the nucleoid.
Another distinguishing feature is that prokaryotic cells are usually smaller than eukaryotic cells.
<em>Your answer is </em><u><em>microbe</em></u><em>, but also known as </em><u><em>microorganism</em></u><em>.</em>
<em>A microbe is any living organism that spends its life at a size too tiny to be seen with the naked eye. Microbes include bacteria and archaebacteria, protists, some fungi and even some very tiny animals that are too small to be seen without the aid of a microscope. Viruses and the recently discovered prions are also considered microbes.</em>
<em>The term microbe is short for microorganism, which means small organism. To help people understand the different types of microbes, they are grouped or classified in various ways. Microbes are extremely diverse and represent all the great kingdoms of life, including the animals, plants, fungi, protists and bacteria (see the tree below). In fact, in terms of numbers, most of the diversity of life on Earth is represented by microbes.</em>
Answer:
Although there are no options but this investigation is a COMPARATIVE investigation
Explanation:
Scientific investigations aims at satisfying a curiosity or a way of explaining natural phenomena. There are three types of investigations viz: descriptive, comparative and experimental investigations.
Comparative investigation is a type of investigation that involves collecting data on different organisms, locations etc for the sole purpose of comparing. It aims at confirming if there is a relationship between i.e. similarities/differences. In this question, two species of squirrels are being observed for their similarities and differences i.e. the aim of the investigation is COMPARISON. Hence, it is an example of comparative investigation
Answer:
They have the ability to contract
Explanation:
Muscle cells are characterized by their *ability to contract* whereas nerve cells help to transmit impulses.
The basic component of all muscle cell is the myofibrils *,a minute, threadlike structure composed of protein. Each muscle cell contains several myofibrils, which are composed of regularly arranged myofilaments of two types, thick and thin.
The cell divides and the chromosomes are reduced by half the amount which is also called cell reproduction
