If a strand of DNA has 48% cytosine what will the percent be for the other nitrogenous bases?

Answers

Answer:

There are 4 possible nucleotides that occur in two complementary sets. If 24% of the DNA is cytosin, the equal share has to be the complementary guanin. That makes 48% GC that leaves 52% AT, thus 26% are adenine and 26% thymine.

This calculation of course wouldn’t work if you were to look at only one DNA strand, where you’d end up with a vastly underdetermined mathematical system.

There are how many types of nitrogenous bases?

Answers

Answer:

4

Explanation:

There are 4 nitrogenous bases and they are Adenine, Thymine, Cytosine and Guanine (in RNA, Thymine is replaced by Uracil)

Answer:

Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).

Explanation:

DNA is a polynucleotide. Each nucleotide is made up of deoxyribose sugar, a phosphate group and nitrogenous base. In DNA, there are four main kinds of nitrogenous bases. Adenine (A), guanine (G), thymine (T), and cytosine (C) are the four bases of DNA (C). Purine bases are adenine and guanine, whereas pyrimidine bases are thymine and cytosine. Base pairing occurs between complementary bases on two strands of double-stranded DNA. By two and three hydrogen bonds, A and G link with T and C, respectively. In RNA, uracil is present instead of thymine.

What are the 3 types of neurons?


Tq! :)

Answers

Answer:

sensory, motor, and interneurons.

Explanation:

For neurons in the brain, at least, this isn't an easy question to answer. For the spinal cord though, we can say that there are three types of neuronssensory, motor, and interneurons.

Answer:

Afferent "Sensory" Neuron

Interneuron "Associative Neuron"

Efferent "Motor" Neuron

Explanation:

The Afferent Neuron or Sensory Neuron receives information from the sensory receptors and carries the impulse from the sense receptors to the central nervous system. In this example the touch receptors in the skin are relaying information through the Afferent "Sensory" Neuron from the environment to the spinal cord.

The Interneuron or the Associative neuron is the transfer station or the decision making neuron. In the case of the reflex arc the Interneuron would make a decision to respond or not respond based upon the intensity of the stimulus.

The Efferent Neuron of Motor Neuron would then return the impulse back to the muscle or gland that would need to respond.

Determine whether each phrase mainly describes surface ocean currents or deep ocean currents. found near the top of the ocean caused by prevailing winds caused by differences in water density caused by differences in water temperature influenced by rotation of earth found closer to the ocean floor

Answers

Influenced by rotation of Earth

caused by prevailing winds

found near the top of the ocean

The phrases that describe deep Ocean currents are :

caused by differences in water

found closer to the ocean floor

caused by differences in water density

Surface ocean currents are found near the top of the ocean, and they are caused by prevailing winds. The wind creates a force on the surface of the ocean, which causes water to move in the direction of the wind.

What are these currents responsible for ?

These currents are responsible for redistributing heat around the planet, making them an important factor in regulating climate.

Deep ocean currents, on the other hand, are caused by differences in water density and temperature. Cold, dense water sinks to the bottom of the ocean, creating a current that can move across the ocean floor.

This process is known as thermohaline circulation, and it helps to redistribute nutrients and oxygen throughout the ocean, making it an important factor in marine ecosystems.

The rotation of the earth also influences ocean currents. Due to the Coriolis effect, surface currents in the Northern Hemisphere tend to flow clockwise, while currents in the Southern Hemisphere tend to flow counterclockwise. This effect is caused by the rotation of the earth and the resulting centrifugal force.

Finally, currents that are found closer to the ocean floor are deep ocean currents. These currents are slower and less visible than surface currents but can have a significant impact on the ocean's circulation and the Earth's climate.
