Assume that a 100 base pair DNA ladder contains 45 cytosines. How many guanines are there?
Answers
Answer:
45 guanines
Explanation:
In a DNA strand, each nitrogen base only pairs with one other specific base.
Adenine pairs with thymine, and cytosine pairs with guanine.
This means that the amount of adenine is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine.
So, if the DNA ladder has 45 cytosines, there will be 45 guanines.

por que un globo con aire se agranda al sol y se achica en la heladera
Answers
Answer: El globo congelado se contrajo porque la energía cinética promedio de las moléculas de gas en un globo disminuye cuando la temperatura disminuye. Esto hace que las moléculas se muevan más lentamente y tengan colisiones menos frecuentes y más débiles con la pared interior del globo, lo que hace que el globo se encoja un poco.

O oxygen
O water
O ATP
Answers
Answer:
glucose
Explanation:
I had a test with this, and it was glucose.
Glucose is a reactant of both cellular respiration and dehydration synthesis
WHAT IS CELLULAR RESPIRATION?
Cellular respiration is the process by which living organisms obtain energy from organic sources. Cellular respiration combines glucose and oxygen as reactants to form carbon dioxide (CO2), water (H2O), and energy.WHAT IS DEHYDRATION SYNTHESIS?
Dehydration synthesis is a reaction whereby two smaller molecules come together to form a larger molecule with the loss of water. An example of dehydration synthesis reaction is the formation of starch from the reaction of glucose molecules with the loss of water.Therefore, glucose is a reactant of both cellular respiration and dehydration synthesis.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.
Which of the following actions would help the skater reach the top of the other side of the half pipe?
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.
Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.
Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.
Answers
The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.
The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.
As the heat energy is lost to the surrounding environment, the skateboard loses velocity.
Bending down by the skateboarder will provide additional energy to make up for the lost energy.
Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.

What is the function of a chloroplast? A. Gamete production B. Cellular respiration C. Fermentation D. Photosynthesis
Answers
Answer:
So i had these notes from a couple of days ago and I’d like to help u out
Explanation:
Photosynthesis
Carbon dioxide enters through the leaf which contains small pours called stomata. The carbon dioxide then enters the cells of the leaf.
Inside the cell carbon dioxide diffuses into the chloroplasts. Where photosynthesis takes place
Chloroplasts use energy from sunlight to transform carbon dioxide and water into sugar and oxygen.
The light reactions
Inside chloroplasts there are these flat membranous sacs called thylakoids.
Thylakoids are the place were light energy is converted into chemical energy in the first phase of photosynthesis the light reactions.
Photosystems
Photosystems are large complexes of proteins and chlorophyll (capture light energy)
Electron transport chain
This chain connects the two photosystems.
Electron carrier
These shuttle (transport that is mainly between 2 things going back and forth) electrons from one photosystem to another
Photosystem
One of the photosystems are used to absorb energy which then excites the electrons that then enter the electron transport chain. These electrons are replaced with electrons stripped from water creating oxygen as a byproduct.
The electrons on the chain
The energised electrons are flowing down the electron transport chain releasing energy that is used to pump hydrogen ions
Hydrogen ions
An atom or molecule that has a net electrical charge due to the loss of one loss or one gained electron.
The electrons on the chain
As the hydrogen ions get pumped out they are then absorbed into the thylakoids
In the photosystem on the right light energy excites electrons and this time the electrons are captured by an electron carrier molecule also known as NADPH
The high concentration of hydrogen ions inside the thylakoid powers ATP synthase producing ATPS the light reactions in the thylakoid have produced two products, ATP and NADPH.
Those two products then power the production of sugar in the Calvin cycle
THE CALVIN CYCLE (C3 Cycle)
The Calvin cycle takes place outside the thylakoids in the stroma (the thick fluid of the chloroplast).
At the beginning of the cycle
carbon dioxide molecules combine with molecules called rubp the resulting molecules go through a series of reactions powered by ATP and NADPH from the light reactions sugar molecules known as g3ps are produced.
G3ps
Most of the g3ps molecules are rearranged back into rubp’s that begin the calving cycle again.
The important product
Then some of the left over g3ps is the remaining g3p sugar, some g3ps are used to build glucose which can then combine into starch or even cellulose
Bits of left over g3ps are also able to break down by cellular respiration, which uses oxygen in the plants own mitochondria, this generates ATPS that can power other work of the plant.
The left overs
Excess oxygen diffuses out of the leaf through the pores while more carbon dioxide goes into the leaf pores.

C. release of neurotransmitters
D. exchange of ions
Answers
Answer:
Exchange of ions.
Explanation:
Release of neurotransmitters activity produces an action potential in nerve cells.
A depolarisation current causes an outburst of electrical activity, which is known as the electromotive force.
This indicates that the resting prospective moves toward 0 mV as a result of some activity (a stimulus).
A cell fires a nerve impulse when the depolarization reaches around -55 mV.
