Answers

Answer: Energy can not be lost, rather it can be converted into other forms of energy , so false.

Explanation:

To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is not required. Thus, the given statement is false.

What is energy cycle in an ecosystem?

The energy flow in the ecosystem is important to maintain an ecological balance in the ecosystem. The producers in a food chain synthesize food by the process of photosynthesis. A part of this energy is stored within the plant species.

The energy cycle in an ecosystem is based on the flow of energy through the ecosystem. The energy from sunlight is converted by the plants them into the growing new plant materials including the flowers, fruits, branches, trunks, and roots of the plants. Since, the plants can grow by converting solar energy directly into their tissues.

The minimum amount of muscles needed to move a joint is ______.
A. 4
B. 3
C. 2
D. 1

Answers

Answer:

C. 2 one muscle contracts while the other muscle relaxes and becomes longer

Explanation:

hope this helps :))

The minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.

What are Muscles?

Muscles may be defined as the bundles of fibrous tissue in animals including humans which consist of long cells that contract when stimulated and induce movements.

Muscles play numerous roles such as maintaining the overall posture of the body, moving the skeleton, storing nutrients, providing stability, assisting respiration and digestion, etc.

A joint is migrated with the cooperation of two muscles in such a way that one provokes the contraction while the other induces relaxation at the same time. This simultaneous activity of both two muscles is responsible for the proper migration of joints.

Therefore, the minimum amount of muscles needed to move a joint is 2. Thus, the correct option is C.

Explain how your model demonstrated energy transformation from thermal energy to mechanical energy during a volcanic eruption.


(I mixed warm water, vinegar, and baking soda)

Answers

Answer:

Well to begin with, the thermal energy is mostly provided by the energy contained in warm water, when mixed with the other two components the chemical units are modified to form a composite solution that will result in an energy release, this energy release generate a movement, which in this case is the eruptive movement simulating the eruption of a volcano.

Explanation:

By mixing the vinegar (which is an acid) with the baking soda (which is a base), they react and transform into water, sodium acetate (a salt), and carbon dioxide (a gas). Carbon dioxide (CO2) is the gas that causes bubbles to form from the eruption of the volcano and balloons to swell.
