Answer: chromatin condenses into chromosomes and can be best observed in prophase.
Explanation: chromosomes can’t be visualised by a light microscope except during cell division (mitosis or meiosis). The individual chromosomes become visible as the chromatin is wound tightly and are most clealry seen in late prophase.
The correct answer is - a front.
On this image, the lines are representing a front, and since the signs are marked with blue color, it means that it is a cold front. The fronts are advancing masses of air. In this case, we have a cold front, thus we have advancing cold air masses in the western part of the US, and in the Great Lakes region and the northeastern part of the country. This means that these areas will be affected by colder air masses, that will bring in higher air pressure, colder weather, and cold winds from the direction from which these cold fronts are coming.
The carrying capacity for a species in an ecosystem is primarily determined by the resources in the ecosystem.
<u>Explanation:</u>
The availability of food, raw materials, water and other resources in that ecosystem are those factors that is used for the determination of the carrying capacity. The factors such as nature, the levels of wastage accumulation, removal of very important things from the system also determines the carrying capacity. a system's carrying capacity may involve matters such as available supplies of food, water, raw materials, and/or other similar resources.
The main components that determines the carrying capacity of an ecosystem are food and other resources, provided, the humans must not disturb the ecosystem for their self survival. The resources limitations and their availability determines this factor to a greater extent.
