The model is in the annex.
The model below states that following the transition, the RNA is in a form known as pre-mRNA where exons and introns may be seen. Splicing is a procedure used to eliminate introns from the RNA molecule since they are not nitrogenous base sequences that can contribute to the creation of proteins. When the introns have been eliminated, the mRNA is prepared for exportation, which involves moving it from the nucleus to the cytoplasm. When the mRNA reaches the cytoplasm, it works with the tRNA, ribosomes, and other molecules to produce a polypeptide chain through a process known as translation, which converts nitrogenous bases into amino acids.The amino acids of the polypeptide chain are arranged in a straight line.

During muscle contraction, all of the following occur EXCEPT
A. Myosin heads bind to actin
B. ATP is hydrolyzed
C. Calcium concentrations in the sarcoplasm decrease
D.Calcium binds to troponin
E. Calcium concentration in the sarcoplasm increase
Answers
During muscle contraction, all of the following occur EXCEPT: C. Calcium concentrations in the sarcoplasm decrease.
The process of muscle contraction is initiated by an action potential that travels down a motor neuron and triggers the release of calcium ions from the sarcoplasmic reticulum (a specialized membrane system) into the sarcoplasm (the cytoplasm of the muscle fiber). The calcium ions then bind to troponin, which causes tropomyosin to move and expose binding sites on the actin filaments.
Myosin heads then bind to actin, forming cross-bridges. ATP is hydrolyzed by the myosin heads to provide energy for the cross-bridge cycle, which results in the sliding of actin filaments over myosin filaments and shortening of the muscle fiber. Calcium ions are actively transported back into the sarcoplasmic reticulum, causing the calcium concentration in the sarcoplasm to decrease, and allowing the actin and myosin filaments to dissociate.
Therefore, the correct answer is C. Calcium concentrations in the sarcoplasm decrease.

Thermodynamics
Heat is thermal energy which is passed on or transferred from one object to another. You may have experienced the many different ways heat can transfer energy; from the rays of the sun, to flow of a breeze.
100% energy in the form of solar radiation
34% reflected from clouds & dust
02% Photosvnines
Wind 1%
Evaporating Water 23%
42% towards heating surface and atmosphere
It takes eight minutes for electromagnetic waves to transfer energy from the sun to the earth. This particular type of energy transfer is known as solar radiation.
As the radiation strikes the earth, molecules within the crust of earth begin to move. As the molecules in the earth begin to collide, the process of conduction begins. If you have ever visited the beach during the warm summer months, you have probably experienced walking on very hot sand. The hot sand is the result of the sun's rays transferring heat through the collision of molecules which is known as conduction. As the land of the earth becomes heated, the molecules in the air above the land are affected. As an air mass becomes warmer, it also becomes less dense and begins to rise. As the density changes and the air mass begin to flow, the process known as convection has begun.

• Identify each phase of thermodynamics, including; conduction and convection
• Describe the movement of the water molecules
Answers
1) The correct answer is c. Radiation. The heat being let off from the bulb is in the form of thermal energy, which is transferred through electromagnetic waves, or radiation.
2) The correct answer is b. Conduction. The energy from the sun is transferred to the black top through radiation, but the heat causes the molecules within the black top to move through conduction, which is the transfer of heat through collisions between molecules.
3) The correct answer is b. Convection. Wind is created by the movement of air masses, which is driven by convection, the transfer of heat through the movement of fluids (in this case, air).
4) The correct answer is a. Waves. Radiation is the transfer of energy through electromagnetic waves, such as visible light, infrared radiation, and ultraviolet radiation.
5) As the Bunsen burner heats the test tube, the water molecules within the test tube begin to move faster and collide with one another, causing the temperature of the water to increase. This is an example of conduction, the transfer of heat through collisions between molecules. As the water near the bottom of the test tube is heated, it becomes less dense and begins to rise, while cooler water from the top of the test tube sinks down to take its place. This is an example of convection, the transfer of heat through the movement of fluids.

Set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks. Each set was watered daily with 50 mL of a 0.1% fertilizer solution. Which statement best explains why the green plants died and the mushrooms survived?
Answers
Answer:
This question lacks options, however, it can be answered based on general understanding.
The green plant died because of absence of LIGHT
Explanation:
Plants (green) are autotrophic organisms i.e. organisms that are capable of synthesizing their own food via a process called PHOTOSYNTHESIS. However, on the other hand, mushrooms (kingdom FUNGI) are heterotrophic organisms i.e. rely on other organisms for energy source and cannot make their own food.
Green plants strictly require light energy from the sun in order to perform the process of photosynthesis. According to this question, a set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks and watered daily with 50 mL of a 0.1% fertilizer solution. The green plants, despite the nutrients and regular watering dies because they were not exposed to LIGHT in order to make their food via photosynthesis. However, since light is not a requirement for mushrooms to obtain food, they will surely survive.
