In this case, the scientific method can be used to confirm weight loss in 75% of cases by a preclinical assay.

A research question is a given question that can be solved by using the scientific method (e.g., can this drug be used to loss weight?).

A hypothesis is a given explanation of an observation from a question of the real world (in this case, the target drug is effective 75% of cases).

The experimental procedure, in this case, may involve taking two sample populations and supplying the target drug to one to observe if is statistically associated with weight loss.

In conclusion, in this case, the scientific method can be used to confirm weight loss in 75% of cases by a preclinical assay.

In the hierarchy of organisms, the ecosystem level is the first that includes abiotic factors. The correct option is B.

The systemic classification of organisms into levels, such as the Linnaean taxonomy, is referred to as biological hierarchy (a biological classification set up by Carl Linnaeus).

It arranges living things into kingdoms, phyla, classes, orders, families, genus, and species in order of decreasing complexity. The eight levels of the present taxonomic hierarchy, from lowest to highest, are as follows: species, genus, family, order, class, phylum, kingdom, and domain.

A multicellular organism's body is organized at many levels, beginning with the cell. Organs are formed from tissues, which are composed of cells. Organs are arranged into organ systems, and then an organism is formed.

Therefore, the correct option is B. abiotic factors.

An engine cut-off lanyard helps to reduce the risk of striking a person in the water with a propeller. The correct answer is option 2.

A propeller is a device with rotating blades that is used to propel a vehicle through a fluid, such as air or water. In the context of boating, a propeller is a rotating device that is attached to an engine and used to propel a boat through the water.

An engine cut-off lanyard is a safety device that is attached to the operator of a boat and to the engine's kill switch. If the operator is thrown from the boat, the lanyard will pull the kill switch, stopping the engine and preventing the propeller from causing injury to the operator or others in the water.

Therefore, an engine cut-off lanyard is an important safety feature that can help prevent accidents and injuries on the water. Option 2 is the correct answer.

Explanation:

Extinction occurs due to the climate change in the polar regions of the earth.

Climate change causes melting of ice caps in colder regions where polar bears live. This change has made it harder for polar bears to successfully hunt seals. This situation will lead to extinction of polar bears in this location because they can't get their food which leads to their death.

So we can conclude that extinction occurs due to the climate change in the polar regions of the earth.
