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.

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.

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.
