E) Intermediate numbers of insects had the greatest positive impact on grass growth.

Answers

Answer 1

B) The grass height was the dependent variable.

E) Intermediate numbers of insects had the greatest positive impact on grass growth.

How insects affect the plant growth?

The grass height was the dependent variable because it depends on the nitrogenous waste of insects and presence of water. The numbers of insects had the greatest positive impact on grass growth because they provides nutrients to plant in the form of nitrogenous water so we can conclude that option B and E are the correct options.

What is TRUE about using bullet comparisons to solve crimes?

A. A Chinese detective did this in 1248.
B. Francis Galton did this in 1892.
C. A Scotland Yard investigator did this in the 1830s.
D. Mathieu Orfila said that this would never be accurate.

Answers

Answer:

C. A Scotland Yard investigator did this in the 1830s.

Reason:

In the 1830s, a Scotland Yard detective was among the first to utilize bullet comparisons to capture a culprit.

A Scotland Yard investigator did this in the 1830s. Therefore, option C is correct.

What are bullets?

A bullet is a kinetic projectile that is fired from a gun barrel as part of firearm ammunition. The majority of handgun bullets are formed of a lead-antimony alloy contained in a soft brass or copper-plated soft steel jacket, although they can also be made of copper, lead, steel, polymer, rubber, and even wax.

A softer lead core is enclosed in a tougher jacket made of steel or cupronickel in rifle and machine gun bullets. Bullets that penetrate armor have an inner core made of hardened steel.

Thus, a Scotland-yard investigator did this in the 1830s. This is true about using bullet comparison to solve crimes. Therefore, option C is correct.

Why is the making of metamorphic rock a chemical change? Explain your answer no using 9009le​

Answers

Answer:

The process of creating a metamorphic rock is a chemical change because we are changing one rock into a whole new different type of rock.

Explanation:

Remember a chemical change is changing the core basis of what something is. Common example of a chemical change is burning wood, when you burn wood that wood turns into ash, which means it's no longer wood.

In this case metamorphic rocks are usually formed by intense heat and pressure, which converts the rock into a different type of rock.

To conclude, metamorphic rocks are formed by intense heat and pressure, which converts a rock into a different rock. "The process of creating a metamorphic rock is a chemical change because we are changing one rock into a whole new different type of rock."

What are nonvascular plants?

Nonvascular plants, such as mosses and liverworts, do not have roots, stems, or leaves like vascular plants. Instead, they rely on diffusion and osmosis to transport water and nutrients to different parts of the plant.

They typically grow in moist environments, where water is readily available, and have simple structures that allow them to absorb water through their surfaces. Nonvascular plants do not have xylem vessels or phloem vessels, which are specialized cells that are used by vascular plants to transport water and nutrients from the roots to the leaves and other parts of the plant.
