Answer:
Inducible
Explanation:
When a gene is expressed only under certain conditions such as the presence of an inducer in the environment to inactivate the repressor, the gene expression is said to be inducible. Here, the presence of substance Y is required as it serves as an inducer by inactivating the repressor protein. When the repressor protein is inactivated, RNA polymerase is able to express the gene. This is an example of inducible gene expression. For example, the presence of lactose is required for the expression of genes of the lac operon.
Fungi lack chloroplasts and are heterotrophic organisms and so require preformed organic compounds as energy sources. With plants: Fungi have a cell wall and vacuoles.
Answer:
They are all the same species
Explanation:
I would say that this is the most logical answer since they are all in the same population. For example, it wouldn't be very logic to have a population of, say, elephants and tigers together. That wouldnt make sence right? Also, if you were to look up the definition of population, it says a particular section, group, or type of people or animals living in an area or country. I hope this helps :)
False, lipid molecules that have the maximum number of hydrogen atoms possible are called SATURATED
1590: Jansen was a Dutch spectacle-maker. He continued to the cell theory because he made the microscope that all future scientists used to see cells. Also, he was the first creator of a compound microscope, the accomplishment is dated around 1590. When he invented the microscope it eventually lead to making other inventions used today
1660: Robert Hooke discovered the cell. When Hooke first saw it he called them cells and the name still stuck. He didn't know the real structure or function of the cell when he first discovered it. This helped scientist bc he discovered the basic unit all the other scientist have to just go deeper into his study
1674: He was a Dutch tradesman and scientist, best known for his work on the development and improvement of the microscope. Anton van Leeuwenhoek is another scientist who saw these cells soon after Hooke did. He made use of a microscope improving lenses that could magnify objects even more.
1838: He proved that all living things are composed of cells and cell products. With the help of schleiden they both concluded that plants are made up of cells. This showed that everything was made up up cells which helped prove what the other scientist had to say
1839: Schleiden found that all plants are composed of cells. He also stated that the different parts of the plant organism are composed of cells.This help scientist know that there are more than one type of cells so they will keep trying to find other cells leading them to more information
1855: He stated that not all plants are made up of cells ,which eventually leads to the creation of the cell theory. This lead to many scientist trying to prove which is right and wrong, leading to many more discoveries to come.
