He could race multiple cars with different weight added on them and do multiple races (just to be sure) and see if his theory was correct, if not he should right down what he has learned from his experience! :D

-You'll never learn if u don't try ;)

JulijaS [17]

<u>Answer:</u>

<em>Decrease in burning of fossil fuels will affect carbon cycle the most. </em>

<u>Explanation:</u>

Carbon compounds circulate within the biosphere as part of carbon cycle.  In terrestrial ecosystems Plants acquire carbon dioxide through photosynthesis and in aquatic ecosystems plankton absorb carbon dioxide.  

Dead plants bodies deposited underground for a large number of years get converted to fossil fuels and the burning of these fossil fuels releases carbon dioxide into the atmosphere.

Carbon dioxide is also released into the atmosphere through processes like respiration and decomposition of dead organic matter. If burning of fossil fuels is decreased it will be the carbon cycle which will be affected the most.

The interaction between which protein and ion initiates muscle coupling?
labwork [276]

Answer:

Troponin and calcium ions.

Explanation:

Troponin is a component of thin filament along with tropomyosin and actin. It is a protein complex to which calcium binds and start the production of muscular force.

Calcium also playing a very important role in muscle contractions, it binds with troponin and helping to move tropomyosin.

When calcium ion attached to troponin, then conformational changes occurs in troponin shape and moves which allow tropomyosin going away from its inhibitory position from the myosin-binding sites on actin. After this, the energized myosin head starts binding to the actin molecules and starts the cross bridge cycle, which helping in shortening the muscle's fiber.

Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to
lozanna [386]
Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. this is an example of how the environment can influence on gene expression.  
<span>
Light has an important role in gene expression in plants by producing a number of light-induced changes. One of the examples of the light effects is that chlorophyll and the proteins required for assembling the photosynthetic apparatus are synthesized together with the enzymes needed for carbon fixation. Gene expression influenced by light includes the regulation at the level of transcription or, alternatively regulation of translation.</span>

Mammals do not produce digestive enzyme B. However, sheep and cattle are two types of mammals that contain microorganisms in the
Pepsi [2]

Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.

Explanation:

Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:

- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.

- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.

Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).

Why is the concept of using the information in DNA to make proteins considered the central dogma of biology
serg [7]

Answer:

"The central dogma of molecular biology explains the flow of genetic information, from DNA to RNA, to make a functional product, a protein. The central dogma suggests that DNA contains the information needed to make all of our proteins, and that RNA is a messenger that carries this information to the ribosomes."
