Answer:
A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein.

Movement caused by warmer fluids rising and cooler fluids sinking is called ______________.
Answer:
Explanation:
convection current
The movement caused by warmer fluids rising and cooler fluids sinking is called convection currents.
What is convection current?The convection currents are the outcome of differential heating. The less dense, that is, lighter warm substances rise, while the denser, that is, heavier cool substance sinks. It is this movement that generates patterns of circulation called convection currents, in water, in the atmosphere, and in the mantle of the Earth.
Thus, convection currents are the answer.

clarify why a diagram of evolution looks more like a bush than a straight line.
Answer:
different horse species could be alive at the same time as others. they all descended from a common ancestor.
Answer: The reason why an evolutionary diagram looks more like a bush than a straight line is the development of new species.
To be more clear - initially we can have one species, and that species will over time start to live in multiple different environments. As the species starts to adapt to the new environment, its appearance and genetics are gradually changing in order for it to have more advantageous traits to survive in the environment. As the time passes, the changes that will emerge in some members will create a new species, and that process will constantly go on, until extinction that is. So we have one species that is an ancestor of multiple new species, thus the family tree, or rather evolutionary diagram, starts to branch out, and as the time passes, it will branch out more and more and take a bush-like looks.

1. Discuss how cells store energy and release energy using ATP. Be specific! Draw the ADP/ATP cycle to help with your explanation
please help,I'm stuck and this is due in a few hours q-q
Answer:
A process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
Explanation:
I actually found this perfect example on the internet. Its the first part to your question.
The hydrolysis of the phosphate bonds in the ATP is used by cells to release energy; whereas the conversion of ADP and phosphate to ATP is used to store energy.
Adenosine thiophosphate (ATP) is the energy coin of the cell.
The hydrolysis of the terminal phosphate bond of ATP is an exergonic reaction that releases energy, which is used by cells to carry out different metabolic functions (e.g. growth, differentiation, reproduction, etc).
When one phosphate group of the ATP molecule is removed by hydrolysis, ATP is converted into ADP and phosphate.
Moreover, during cellular respiration, cells catalyze the formation of phosphate bonds when ADP is combined with phosphate to form ATP.
In conclusion, hydrolysis of the phosphate bonds in the ATP is used by cells to release energy; whereas the conversion of ADP and phosphate to ATP is used to store energy.

A microwave can reheat 1 cup of coffee in 30 seconds. It takes a coffee maker 10 minutes to brew 12 cups of coffee. If
the coffee maker requires 900 watts of power and the microwave requires 1200 watts of power, does it require more
energy to brew 12 cups with the coffee maker or reheat 12 cups of coffee in a microwave?
The coffee maker requires more energy.
The microwave requires more energy.
They require the same amount of energy.
The answer cannot be determined without more information.
Answer:
It takes more energy to reheat coffee in the microwave
Explanation:
1 cup= 30 seconds
12 cups= 30*12= 360 seconds
360/60= 6 minutes
It takes 6 minutes to reheat 12 cups of coffee.
900 watts/10 minutes= 90 watts per minute
1200 watts/6 minutes= 200 watts per minute
Answer:
The coffee-maker requires more energy.
Explanation:
Explanation: At 30 seconds a cup, the microwave will require 6 minutes to reheat the 12 cups of coffee. This is 1/10 of an hour, so the microwave uses 1200/10 = 120 watt-hours of energy. The coffee-maker requires 10 minutes to brew 12 cups of coffee, or 1/6 of an hour. This means it will use 900/6 = 150 watt-hours of energy.

heterogeneous mixture
Explanation:
A heterogeneous mixture contains particles that are not the same, can be separated by physical means, and are not distributed the same throughout the mixture. Trail mix fits this description perfectly.
Trail mix is a heterogeneous mixture, which is in option D, as trail mix is a popular snack that typically consists of a combination of various ingredients, such as dried fruits, nuts, seeds, and sometimes chocolates or candies.
Trail mix is a type of snack that typically consists of a combination of ingredients like dried fruits, nuts, seeds, and sometimes chocolates or candies. These ingredients are intentionally mixed together to provide a variety of flavors, textures, and nutritional elements. Unlike homogeneous mixtures, where the components are uniformly distributed and appear the same throughout, heterogeneous mixtures have visible differences and variations within the mixture. In the case of trail mix, you can see the separation between the various ingredients, and they can be easily distinguished from one another.

Answer:
well, i think the correct answer is
B_ a hindrance
For radio reception, diffraction is hinderance. The phenomenon of waves interacting with particles is known as diffraction.
What is diffraction?
The phenomenon of waves interacting with particles is known as diffraction. This happens when the aperture's or obstacle's size is of the same order of magnitude as the wave's wavelength.
The wave transmitted through an aperture that has a width smaller than its wavelength expands out completely and behaves like a point source of waves.
The small bending of light as it travels around an object's edge is known as diffraction. The ratio of the wavelength of the light to the opening size determines how much bending occurs.
Therefore, For radio reception, diffraction is hinderance. The phenomenon of waves interacting with particles is known as diffraction.

If cells don't work together, what would happen to the organism?
Answer:
If cells do not work together, the organism would die.
Explanation:
Production would likewise be impossible if the Golgi did not generate secretory vesicles, thus organisms would perish quickly if cells did not cooperate.
Because secretion would be impossible, a build-up of substances would ensue, causing other compartments in the cell to malfunction.
Food, germs, and bacteria would not be brought into to the cell to decompose down and cause illness.
