Answer:
The plasma membrane maintains homeostasis in the cell by keeping cell contents in and foreign material out, and by providing controlled routes for the transportation of fuel, fluids and waste.
The plasma membrane is very important because it allows a cell to maintain homeostasis by:
Controlling the flow of foreign substances into the cellControlling the movement of materials out of the cell Transporting materials within the cellHomeostasis refers to the inner environment of the cell being maintained such that it can carry out its duties.
The plasma membrane helps with that by first controlling what materials come into the cell to ensure that the inner environment isn't disrupted. It also limits those going out for the same reason.
Substances need to move around in the cell and the membrane handles this as well to ensure that substances get to the part of the cell where they help with maintaining the cell.
In conclusion, the plasma membrane is hugely important to the cell as it maintains homeostasis.

Which statement describes surface features called maria on the moon?
A. High lands and mountainous areas
B. Layers of dust and rock
C. Deep areas of cooled lava
D. Deep, rocky and barren valleys
Answer:
B is the right answer I think.
The statement describes surface features called maria on the moon as the deep areas of cooled lava. Option C is correct.
In reality, maria are vast basins that contain lava flows marked by crater formations, ridges, and faults, as well as straight and winding valleys known as rilles, and are completely dry.
There are roughly 20 major regions of this type, with most of them (including the largest) located on the face of the Moon that is always facing the Earth.
During this time, the moon experienced large-scale collisions with asteroids that cracked the surface of the Moon, resulting in large craters.
Liquid magma beneath the Moon’s surface flowed through the cracks, filling the craters and cooling them. These craters are what we refer to as lunar maria.
Therefore option C is correct.

Question 3
Which statement below is correct?
A. Photosynthesis produces ATP, and cellular respiration requires light
energy
B. Photosynthesis produces carbon dioxide, and cellular respiration
produces sugars.
C. Photosynthesis and cellular respiration occur in both plant and
animal cells.
D. Photosynthesis produces the oxygen required for cellular respiration.
Answer:
B is the correct answer.
A is incorrect because respiration is always occuring in animals and plants, therefore it means it does not require the presence of light. Photosynthesis does produce ATP, though.
Not C because photosynthesis does not occur in animals
Not D because they both are different processes. They don't really depend on each other, though they could occur at the same time.

Which regions of the river in the figure above contain more nutrients than the other regions? Explain.
Answer:
Hello. You don't know what this question refers to, but the regions of the rivers that have more nutrients are those that have a lot of algae and vegetables and few fish and marine animals in general.
Explanation:
The accumulation of nutrients in rivers, mainly nitrogen and phosphorus, stimulates the primary production of this environment, which is represented by the excessive growth of algae and other vegetables, which often end up dominating the entire surface of the river. This is very harmful for aquatic animals as it decreases the oxygen concentration of the river, leading to the death of several animals, especially fish. For this reason, we can say that the areas with the most nutrients in a river will have a large number of algae and a low number of fish.

The ostrich is a bird. However, it has traits that are different from those of the birds we typically see flying around our neighborhoods. Using credible sources, investigate the environment and adaptations of ostriches to explain how they evolved to survive in their environment.
Answer:
The reason for the Ostriches way of being like this with the adaptions of strong legs and increased weight and it being flightless bird are because of the environment they live in where the air is to dangerous and also of the predators that live in their environment. It is flightless and is because of the environment it lives in causing them to have to change and adapt and is the reason why they are not like other birds that can fly and why they have such strong legs instead.
Explanation:hope this helps
Ostriches have evolved unique traits to survive in their environment, which is primarily characterized by vast open spaces and arid landscapes.
Ostriches are native to the African savannas and deserts, where they have adapted to cope with the challenges of their environment. Their long, muscular legs allow them to cover large distances efficiently, making them well-suited for evading predators and finding food and water in the expansive and often unforgiving landscapes they inhabit.
Ostriches have evolved differently from typical flying birds, as their wings have become reduced in size. While they cannot fly, their wings serve as important stabilizers during running and courtship displays. These adaptations are a response to the selective pressures of their environment, where flight is less advantageous compared to running.
