The mutation mentioned here is a dominant negative.
Define mutation.
A mutation is a change in our DNA sequence that can be brought on by environmental factors like UV light and cigarette smoke or mistakes made when the DNA is copied.
When a mutant receptor prevents the function of the wild-type (WT) version of the receptor, the condition is known as a dominant-negative (DN) mutation.
A DN mutation generally results in a mutant polypeptide whose activity is reduced in comparison to the co-expressed wild-type protein. Dominant-negative mutations are known as antimorphs, indicating that they have the opposite impact of the gene from which they were produced, according to an early genetic study.
Oncogenes are examples of DN mutations that arise spontaneously. When only one copy of the gene is functioning, haploinsufficiency is frequently used to compare negative dominance . Since it directly affects the phenotypic diversity in this situation, the expression level of this gene is significant. Trisomy 21, which is brought on by errors in the genes producing transcription factors and other key proteins, is a classic example of a condition brought on by haploinsufficiency.

B cells have B cell receptors (BCRs) on their surface, which they use to bind to a specific protein. Once B cells bind to this protein, called an antigen, they release antibodies that attach to the antigen and prevent it from harming the body. The antigen receptor on most T cells, the α:β T-cell receptor, is composed of two protein chains, the α T-cell receptor and the β T-cell receptor, and resembles in many respects a single immunoglobulin Fab fragment. T cell receptors are always membrane bound. The membrane-bound immunoglobulin on the surface of B cells serves as the cell's receptor for the antigen and is known as the B cell receptor (BCR).

at the end of tca cycle, glucose is converted to the final product, co2, and all the energy are released in the form of atp/gtp.
The end products of the TCA (tricarboxylic acid) cycle include 6 NADH, 2 ATP and 2FADH2.
The tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or the citric acid cycle, is a series of eight-step processes, where the acetyl group of acetyl-CoA is oxidized to form two molecules of CO2 and in the process an ATP is produced. High energy reduced compounds, NADH and FADH2 are also produced. Two molecules of acetyl-CoA are produced from each molecule of glucose, so two rounds of the Krebs cycle are required, resulting in four CO2, six NADH, two FADH2 and two ATP. The tricarboxylic acid cycle (TCA cycle) is the second stage of cellular respiration, the three-step process by which living cells break down organic fuel molecules in the presence of oxygen to grow and divide the energy obtained after harvesting.

which is more resistant to fatigue, cardiac or skeletal muscle? what is the anatomical basis for this difference and why is it important?
Cardiac muscle cells contain many mitochondria that provide the necessary energy for the cell in the form of adenosine triphosphate (ATP), making them highly resistant to fatigue.
Because cardiac muscle has more mitochondria than skeletal muscle, it is resistant to fatigue. It is up to 35 percent mitochondria, compared to just 1-2 percent in skeletal muscle. Mitochondria are necessary for the generation of ATP, which supplies cells with energy. The rapid, involuntary contraction and relaxation of the heart muscle are vital to pumping blood throughout the cardiovascular system. To achieve this, the structure of the heart muscle has distinct characteristics that allow it to contract in a coordinated manner and resist fatigue. This is mainly because the heart is made of cardiac muscle, which consists of special cells called cardiomyocytes.

The three main areas of investigation accompanying a new fossil find are impression fossils, trace fossils, and replacement fossils. Fossils are the remains or traces of ancient life that have been preserved by natural processes.
Impression fossils preserve the prints or impressions of extinct plants or animals. The plant or animal makes an impression when it touches down in mud, silt, or sand. It eventually vanishes, yet the effect endures. The mud, silt, or sand becomes rock and a fossilized impression is left behind. Trace fossils document the behavior of extinct creatures. In the soft mud, silt, or sand, these animals leave their prints or scats, which leave impressions. The soil preserves a sign of the animal when it solidifies into rock, just way impression fossils do. Replacement fossils are exact copies of objects that were once alive, like trees and aquatic life. These living things become imprisoned, perish, and are covered with water that is mineral-rich. The organic components decompose and are replaced by silica, a hard mineral. The minerals fill in the gaps and produce a substitute or duplicate fossil of the live object.

This is the case of complete dominance.
What is complete dominance?
When one allele, or "version," of a gene completely obscures another, complete dominance occurs. Being "dominant" over the trait which is not expressed refers to the trait that is expressed. The majority of organisms are diploid, which means that each gene is received twice, once from each parent. An organism may possess a gene that has undergone a harmful mutation and be able to function since it possesses a healthy copy of the gene due to the protective effect of having two copies of each gene. Due to the fact that most organisms, including you, have two copies of each gene, scientists use the terms "dominant" and "recessive" genes to describe which one manifests as a specific characteristic.
In this the a1 and b1 act as a dominant allele , which add to the color and a2 and b2 are recessive one , which are completely masked by the other one . So it adds 0 unit to color .

As a result, three different animal groups—arthropods, cephalopod molluscs, and vertebrates—developed very complex brains.
What is bilateria?The majority of animal phyla belong to the big group known as the Bilateria, which is distinguished by cephalization. These are able to move by contracting their muscles, and their body plans feature a front end that is the first part of the body to be stimulated as the animal moves forward. As a result, many of the body's sense organs, including those that can detect light, chemicals, and gravity, have developed in the front end. Additionally, a group of nerve cells that can process the data from these sense organs frequently exists. In some phyla, this group of nerve cells forms a brain, whereas in others, it forms one or more ganglia.

which joint is highlighted? which joint is highlighted? sternoclavicular sternal end acromioclavicular acromion
Joint which is highlighted is : acromioclavicular. The acromioclavicular joint is formed by the cap of the shoulder and the collar bone and is held together by strong ligaments.
What is the function of acromioclavicular (AC) joint ?The AC joint is a plane type synovial joint, which allows only gliding movement under normal physiological conditions. It attaches the scapula to the thorax, hence it allows an additional range of motion to the scapula and helps in arm movement such as shoulder abduction and flexion.
AC joint inflammation causes pain on the top of the shoulder and also at the point where the collarbone meets the highest point of the shoulder blade . Pain may spread to the lower part of the side of the neck or ear.
