<h3> $\pink{\bigstar}$ Additional Information:-</h3>

A Synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells. Synapses are the key to the brain's function.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

The term synapse was first introduced in 1897 by Michael Foster in his "Textbook of Physiology" and derived from the Greek synapsis, meaning "conjunction."

Fill in the blanks: The original organism is called the _____________, and new organisms are called the _____________.

NARA [144]

Answer:

The original organism is called the parent (ancestor) , and new organisms are called the offspring.

Explanation:

Reproduction is one of the characteristics of life. Every living organism tends to give rise to another organism. The organism which gives rise to another organism is termed as the parent. The organism which is born is known as the offspring.

There are two basic methods of reproduction. An organism can give rise to another organism by the method of asexual or sexual reproduction.

During asexual reproduction, identical copies of the parent organism are made. During sexual reproduction, two organisms reproduce to produce non-identical offsprings.

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?

Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.
