Answer:
Activator protein binding is thought to cause DNA to loop out, bringing the activator protein into physical proximity with RNA polymerase and the other proteins in the complex that promote the initiation of transcription. Different cell types express characteristic sets of transcriptional regulators.
Answer:
Passive transport is the movement of particulars across the membrane from area of <u>high</u> to an area of <u>low</u> concentration.
Explanation:
Passive transport is a transmembrane cellular transport mechanism characterized by the fact that it does not require energy.
What enables passive transport is the concentration gradient of a particle, which moves across the membrane from a site of high concentration to a site of low concentration.
Two known forms of passive transport are <u>simple diffusion</u> and <u>facilitated diffusion</u>.
Answer:
Tropical birds are often brightly colored and have long bills. They're omnivores that eat seeds, nuts, fruit and insects. Some tropical birds eat small lizards and animals. Parakeets also belong to exotic and tropical birds.
So 1g is 1000mg.
You would need to eat 3500mg worth of a bannana, so divide 323 with 3500..
3500 / 323 which is 10.80.. So you'd need to eat about 11 small bannanas.
Answer:
<em>The answer is plant cells they would be the type of cells you would find a permanent. an animal cell would not have that.</em>
Explanation:
<em>The reason plant is the answer is because plant cells contain a cell wall made of cellulose to strengthen the cell. They also have a permanent vacuole which is filled with cell sap to help keep the cell turgid.</em>
<em>The reason why animal cells don't have a permanent is because Animal cells may have more than one vacuole, and they are smaller than a plant cell's. Vacuoles are used to store materials in the cell that may be used by the cell or wastes that must be moved out of the cell.</em>
