The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.

The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. ... Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

Choose the scientific question. A. Would you like to have a frog as a pet? B. Who is the smartest biologist alive today? C. Whic

TiliK225 [7]

Answer:

The correct option is D) How is the number of frogs in Massachusetts affected by pollution

Explanation:

A scientific question can be described as a question which can be answered through the scientific method of research. Based on the scientific question, a hypothesis can be formulated. For example, for the option D, the hypothesis can be 'if the pollution increases, then the number of frogs decreases.' A hypothesis is a tentative statement which can be tested through experiments. Based on these experiments, results are formulated and conclusions are drawn. The question mentioned in option D can be answered through this method hence, it is the correct option.

Which of these gymnosperms are known to be important in maintaining the balance of carbon in an ecosystem?

CaHeK987 [17]

The correct answer is: [D]:

___________________________________________________

→ " redwood tree forests " .

___________________________________________________

Note: Let us consider the other answer choices.

___________________________________________________

Choice: [A]: "garden flowering plants" ; is incorrect — since these are not generally considered to be part of a true or traditional "ecosystem" ; and especially since "garden flowering plants" are, in fact, "flowering plants" — which means that they are "angiosperms" — Not "gymnosperms ".

→ Rule out: " Choice: [A] " .

__________________________________________________

Choice: [B]: " ferns and liverworts " ; is incorrect — since both ferns — as well as liverworts — are Not "gymnosperms ".

Liverworts are "bryophytes" {which lack true vascular tissue] ; and ferns are "pterophytes" ["seedless vascular plants"].

→ Rule out: " Choice: [B] " .

___________________________________________________

Choice: [C]: " mosses and horsetails "; is incorrect ; since both mosses — as well as horsetails — are Not "gymnosperms ". Mosses are "bryophytes" (see aforementioned) ; and horsetails are "non-seed bearing plants" that spread vegetatively [underground; by asexual reproduction — and Not by seed .].

→ Rule out: " Choice: [C] " .

__________________________________________________

Choice: [D]: " redwood tree forests " ;

— is the only answer choice provided that is a "gymnosperm".

Furthermore, the "redwood tree" is a conifer (i.e. "coniferous; or, "cone-bearing" plant} that reproduces through seeds spread by "cone") — and all "conifers" are a type of "gymnosperm."

Furthermore, "redwood trees" grow large and tall, and redwood forest communities within an ecosystem; due to there size and presence, are: "known to be important in maintaining the balance of carbon in an ecosystem."

__________________________________________________

→ As such, the correct answer is:

__________________________________________________

→ Answer choice: [D]: " redwood tree forests " .

The sensory receptors in the nose and tongue are stimulated by......

mart [117]

Answer:

chemicals

Explanation:

The nose and the tongue are two of the five sensory organs (others being skin, eyes, ears). These organs contain certain cellular structures called SENSORY RECEPTORS, which respond to different stimulus in the environment.

Nose and tongue are two organs that possess a type of sensory receptor called CHEMORECEPTORS. Chemoreceptors are receptors that respond to chemical stimuli. In other words, the receptors in the nose and tongue are stimulated by chemical substances e.g. food chemicals for TONGUE, chemicals in air for NOSE.
