Answer:

A dolphin breathes through a single blowhole on the top surface of its head. The blowhole is covered by a muscular flap, which provides a watertight seal.

A dolphin holds its breath while below water.

The dolphin opens its blowhole and begins to exhale just before reaching the surface of the water. To open the blowhole, the dolphin contracts the muscular flap.

What is a category of ai that attempts to emulate the way the human brain works?
KIM [24]

Category of AI that attempts to emulate the way the human brain works neural network.

A neural network is a biological neural network made up of biological neurons or an artificial neural network used to solve artificial intelligence (AI) problems.

Artificial neural networks model biological neuron connections as weights between nodes. An excitatory link is represented by a positive weight, whereas an inhibitory connection is represented by a negative weight. Each input is given a weight before being added together.

These artificial networks can be applied to adaptive control, predictive modelling, and other tasks where a dataset can be utilised to train them.

If a cytosine base is substituted for by a thymine base in a DNA segment during DNA replication, the sequence could code for the wrong amino acid during translation.

The change in the sequence of DNA is known as mutation.

When a base substitution occurs in the sequence of a DNA during replication, the genetic information in the region where the substitution occurred becomes compromised.

During transcription, the process of encoding genetic information on DNA into RNA, the base substituted is also transcribed along. If cytosine is substituted by thymine, adenine is transcribed instead of guanine.

During the translation of the genetic codes, the wrong amino acids might end up being translated due to the substituted base, leading to a faulty protein.
