TT and Tt are possible genotypes of a tall pea plant as the resulting phenotype of both possible genotypes result in a tall pea plant.
<span>The trilobites seen in this image was once found widespread in the ocean. Something Changed To Limit and finally abolish their success. What do scientists use this example as proof of ? The answers are A. life changes over time and B. Vesitigial organisms once had a function in ancient times.The trilobites first appeared in the Cambrian period and though they entered a decline int the Devonian period, some of them survived until Permian time or for a period of 270 million years. They were divided into 3 segments and were early examples of arthropods. They tended to live on or near the bottom of the oceans and were scavengers in part and as well as living on the ocean floor some swam and fed on plankton. </span>
Answer:
Explanation:
The energy driving the movement of molecules during passive transport comes from differences in the concentration of the molecules on either side of the membrane with the molecules tending to move from the side of higher concentration to the side of lower concentration because of their net thermal movement.
Because there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done
How is energy used to move?
Molecules do not stop moving once they reach equilibrium. Passive Transport (no energy needed). The movement of particles from an area of high concentration to low concentration. Particles pass right through the cell membrane. the (passive) movement of large particles or substances across the cell membrane through protein channels.
I hope it helps you!
Characteristics that are always present in living organisms are _____. Answer. Living organisms are feeding, moving, breathing, excreting, growing, reproducing, and are sensitive.
Answer:
The process illustrated in the diagram is the non light dependent reactions of photosynthesis termed as Calvin Cycle.
Explanation:
- Two molecules of 3-phosphoglycerate (3-PGA) are produced or released from step one to step two of Calvin cycle.
- The source of energy that helps to start step one are ATP and NADPH, mainly derived from the light dependent reaction.
- The oxygen molecule thus formed by splitting of water is release to the nature as oxygen, which living organisms utilizes in respiration.
- Carbon dioxide comes from the atmosphere to start the process.
- Light reactions occurs in the thylakoid membranes of the plant organelles namely chloroplasts.
- Non-light dependent reaction or Calvin cycle takes place in the stroma chloroplasts.
