Answer:
Organelle
Explanation:
The general name given to membrane bound structures eukaryotic cell that perform specific function for necessary cell survival.
The answer is d.
Meiosis is a kind of cell division that produces daughter cells that are genetically different to parent cells and contains half number of chromosomes comparing to parent cells.
At the beginning, the parent cell duplicates its chromosomes just like mitosis. The cell divides and leads to 2 genetically identical daughter cells.
This is where mitosis ends. But in meiosis, the 2 cells produced divides again, but without duplicating it's chromosomes. Therefore, this leads to 4 daughter cells at the end, each with halved number of chromosomes.
When a cell has a halved number of chromosomes, it's said to be haploid.
This is usually common in gametes so that biodiversity can be achieved.
Therefore, the answer to this is d.
humans cannot impact one of Earth's systems without impacting the others because Earth's systems are interconnected. They interact with each other, moving matter from one system to the other. Changes to the atmosphere brought about by human activity eventually lead to changes in the biosphere and hydrosphere.
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.
