The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
Answer:
The correct answer is - scanning electron microscope.
Explanation:
SEM or a scanning electron microscope is that produces an image by an electron beam over the sample surface to scan. The electrons of the beam interact with the sample producing various signals that allow providing information about the composition and topography of the individual sample. The magnification of the SEM is in between 20X to 30000X
Thus, the correct answer is - scanning electron microscope.
Answer:
Gregor Mendel
Explanation:
Genetics as a scientific discipline stemmed from the work of <u>Gregor Mendel </u>in the middle of the 19th century.
The correct answer is B. Modern technology allowed for larger expanses of land to become cultivated, so farming took over many natural areas that were important for wildlife.
Explanation:
In the last decades, the creation of agricultural technology has increased the efficiency of growing crops. This means now, all the process is more efficient, which leads to more products to be sold and an increase in profit. However, the possibility of large scale agriculture has caused more land is used for this purpose. This often implies natural ecosystems such as forests are destroyed and the land of these ecosystems, which is usually rich in minerals, is used for extensive agriculture. This is a negative consequence of agricultural technology as natural areas important for wildlife are taken for human profit.
Prokaryotic: before nucleus, no membrane bound organelles, and single celled microscopic organisms
eukaryotic: true nucleus, has membrane bound organelles, and multi cellular or unicellular organisms
therefore it would be letter <span>B. cell membrane and cytoplasm</span>
