A student is measuring the effect of different temperatures on the effect of enzymes in biological systems. What temperature ran
viktelen [127]

Answer:

A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C  

Explanation:

Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).

That automatically eliminates Option B.

I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.

Option D is wrong because it includes no temperatures above body temperature.

Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.

That leaves Option A as the best answer. It includes only one temperature above 40 °C.

natima [27]

Endemism

Endemism is the state of a species being native to a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere.

Explanation:

Endemic species are those that are found in just one region and nowhere else in the world. For example, kangaroos are originally endemic to Australia and are found nowhere else in the world. ... The Tasmanian Tiger is one such animal that was endemic to Australia, Tasmania and New Guinea. But now, it is extinct.

Why does a hormone only act on specific cell types in an organism and not others?
Vilka [71]

Answer:

c) A cell must have the appropriate receptor before it can bind to the hormone.

Hormones are chemical signals that are secreted into the circulatory system acting as regulators within the body, and even though they can reach any part on the body, <em>only certain types of cells are equipped to respond, these cells are known as target cells, when the hormone reaches a cell with an adequate receptors it triggers a signal transduction and then a response.</em>

Therefore the correct answer is c.
