What is the best explanation for species diversifying to fill each new niche? A. The plants chose the niche that they "liked" best. B. Ln each niche, the fittest plants were able to leave more offspring than other plants. C. Successive generations of plants adapted to each new niche. D. Only some plants could get nutrients from the soils.
Answer:
C. Successive generations of plants adapted to each new niche.
Explanation:
The process by which species with diverse ecological and morphological variations specialized for various niches arise from a common ancestor is known as adaptive radiation.
Due to variety in habitat and diet, species diversify in order to fill the various niches within the same environment. For example, in the Finches observed by Darwin in the Galapagos islands, adaptive radiation is seen in how their beaks have changed in size and structure so that they now became adapted to different diets. Some species eat mostly animals such as insects, whereas others became adapted to feeding on seeds or plants.
In the case of the plants, adaptive radiation would also play a role in how the species diversified to fill each new niche.

10 Points! Please help! What would a sample adaptation for a plant and animal be for a persistent drought, river changing course, and air pollution?
Answer:
ok i said for the first box: they need little water and for animals: they are reptiles or like a lot of sun. for the next 2 im stuck!!!
Explanation:
Adaptation is the process of adjustment to new conditions in order to survive and thrive.
What is adaptation?Adaptation is the process of adjustment to new conditions in order to survive and thrive. Here are some possible adaptations that plants and animals could develop in response to persistent drought, river changing course, and air pollution:
Persistent drought:
A plant could develop a deep taproot system that can reach water sources deeper underground.An animal could develop the ability to conserve water, such as through the production of highly concentrated urine or feces.River changing course:
A plant could develop the ability to disperse seeds over longer distances, allowing it to establish itself in new areas as the river changes course.An animal could develop the ability to swim or navigate through new waterways created by the changing river course.Air pollution:
A plant could develop leaves that are better adapted to filtering out pollutants, such as thicker and hairier leaves or specialized pores that can trap and remove pollutants.An animal could develop stronger lungs or respiratory systems that can filter out pollutants, or the ability to move to areas with cleaner air.These are just a few examples of the types of adaptations that plants and animals could develop in response to these challenges. In reality, the specific adaptations that evolve will depend on a variety of factors, including the specific species, the severity and duration of the challenge, and the available resources and genetic variability.

A cell membrane is more flexible than a brick wall. Why might many cells benefit from a flexible cell membrane? and A building has different types of openings, such as windows and doors. Do you think a cell also has different types of openings? Give an explanation for your answer. I NEED HELP NOW I HAVE TO SUBMIT
Answer:
plant: This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
animal :This human cheek cell is a good example of a typical animal cell. It has a prominent nucleus and a flexible cell membrane which gives the cell its irregular, soft-looking shape.
Like most eukaryotic cells, this cell is very large compared to prokaryotic cells. For scale, notice the pair of dark blue bacteria cells sticking to the right edge of the cheek cell. The bacteria are only a fraction of the size of the nucleus, but their tiny size is typical for bacteria.
A cell membrane's flexibility aids in the selective passage of substances across it. Endocytosis, a mechanism that enables amoeba to take in food particles from the environment, is made possible by the flexibility of the membrane.
What make cell membrane to be flexible?The majority of natural phospholipids' fatty acids include one or more double bonds, which cause the hydrocarbon chains to twist and are challenging to pack together.
The interior of the membrane can displace freely due to the prolonged hydrocarbon chains of the fatty acids, getting the membrane itself negotiable and supple.
Key fatty acids include arachidonic and docosahexaenoic acids. Due to its four double bonds, arachidonic acid's proportion in phospholipid tails can be slightly increased to improve membrane flexibility.
Therefore, cell flexibility is important for cell to function.

What is tectonic plates?
Earth’s tectonic plates are part of the planet’s crust which correctly describes Earth’s tectonic plates. Huge fragments of the upper mantle and crust make form tectonic plates. Both continental and oceanic crust make up their composition. Mid-ocean ridges and the significant faults that delineate the plate boundaries are subject to earthquake activity.
Our globe would look drastically different if it weren't for plate tectonics. We have a stable climate, mineral and oil deposits, and oceans with a chemical balance that supports life thanks to the continuous recycling of the Earth's crust.
The tectonic plates, which have a thickness of about 100 km, are made up of this crustal layer of the globe. These plates, which continue to float on the warm and thick mantle, collided to create the mountains.
Therefore, The arrows on either side of the fault represent the relative movement of the two tectonic plates. The type of boundary is represented in the diagram is convergent. Thus, option B is correct.
