During a science lab the teacher provided Michael with a triple-beam balance, a ruler, and four cube-shaped metals. Based on Michael's calculations and the table below, the conclusion can be BEST made Substances can be identified by their density
what is density?
Density refers to the mass of a unit volume of a material substance. The formula for density is represented by d = M/V, where d is density, M is mass, and V is volume.
It is commonly shown as units of grams per cubic centimeter, it can also be expressed as kilograms per cubic meter .
Density can used to define how different materials interact when mixed together. For example Wood floats in water because it has a lower density, while an anchor sinks because the metal has a higher density.
Density can be applied in pipe design, shipbuilding, helium balloons, weight distribution in the aero plane, and the fact that ice floats on water.

Explanation:
The electron chain produces much more ATP than glycolysis or the Krebs Cycle but it needs them to happen in order to take place. How do the first two steps make the last one possible?
The first two steps of cellular respiration provides the raw materials (NADPH and FADH2) for the third process.
CELLULAR RESPIRATION:
Cellular respiration is the process by which living organisms obtain energy (ATP) by breaking down food molecules in their cells. Cellular respiration occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain. Electron transport chain (ETC) produces the highest amount of ATP (36), however, the products of glycolysis and Kreb cycle are needed for ETC to commence. These products, which are raw materials (electron carriers) for ETC are NADPH and FADH2 molecules. Therefore, the first two steps of cellular respiration provides the raw materials (NADPH and FADH2) for the third process.Learn more at: https://brainly.com/question/24372542?referrer=searchResults

Animals can help plants reproduce in a variety of ways. Which behavior can end up being more harmful than helpful?
A. Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.
B. Iguanas and tortoises eat leaves, fruits, and flowers, relying on each as important
seasonal food sources.
C. Insects like bees and butterflies drink nectar, carrying pollen from one flower to
another.
D. Hummingbirds drink the nectar of flowers, and they will defend their territory in
order to secure their food supply.
Answer:
B
Explanation:
The behavior that can end up being more harmful than helpful when it comes to plant reproduction is iguanas and tortoises eating leaves, fruits, and flowers as important food sources.
When plant tissues or organs are removed, it affects the reproductive potential of such plants. Thus, Iguanas and tortoises feeding on plant tissues and organs is quite detrimental to plants and may offer very little to no benefits.
Birds help disperse seeds by feeding on fruits and dropping the seeds along with their feces. Insects like bees help pollinate flowers and hummingbirds help protect plants from certain predators. All these actions help plant reproduction.

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.
