Explanation:
A mutation is a sudden change, and in this case, it's in gametes.
If the change happens because of or during meiosis, the mutation is carried and may affect phenotypic change in offspring. This is because the gametes are the buiding blocks for a human being's genetic code. If there is a change in it's genetics, there will be a change in how it looks.
The process of mutation in gametes results in phenotypic changes in offspring by the fact that the gametes are the building blocks of organisms that govern each and every essential function for the survival of living organisms.
What is Mutation?A mutation may be defined as sudden, stable, and inheritable changes in the genetic material of a living organism. An organism that undergoes an event of mutation is known as a mutant. While the agents that cause an event of mutation are known as mutagens.
When a mutation is induced in the gamete cells of living organisms, it may be directly inherited from parents to their offspring the fact that they are the building blocks and functional components of the living organisms. So, they result in alterations in the phenotypic expression of offspring.

2. How can dominance and expression of alleles explain the differences between these fraternal twins?
Answer:
Fraternal twins are from two seperate eggs.
Explanation:
The first part of the question is missing but any difference between fraternal twins can be explained by the fact that two seperate eggs are fertilized during the pregnancy so they have different genomes which leads to having different dominance of different genes and this leads to different expressions of this genes.

A) 20%
B)30%
C)40%
D)60%
A DNA segment, composed of 120 nucleotides, code for a protein molecule is a gene.
A DNA molecule that 30% of its nucleotides are adenine contains 30% guanine nucleotides.
What is a gene?A gene is a region of DNA which contain information for the synthesis of a protein or any other product.
A DNA segment, composed of 120 nucleotides, code for a protein molecule is a gene.
In a DNA molecule, the ratio of adenine nucleotides is equal the ratio of guanime nucleotides due to base pairing.

What is the function of mitochondria in muscle fibers?
Answer:
During strenuous exercise, the rate of energy use in skeletal muscles can increase by more than 100-fold almost instantly. To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell's “power plants,” convert nutrients into the molecule ATP, which stores energy.

Identify the statement below that is NOT a principle of evolution.
O Populations evolve, individuals do not
O Negative adaptations will become more common in a population
O Variations occur naturally within a population
O Adaptations help individuals compete successfully for survival
B) negative adaptations will become more common in a population
negative adaptations will become more common in a population.
What is Evolution?According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognizable differences are the result of changes made by subsequent generations.
More than 2 million species of organisms already in existence have been recognized and documented; many more are still undiscovered, with estimates ranging from 10 million to 30 million.
The amazing variability in size, form, and mode of existence, from tiny bacteria with a diameter of less than a millionth of a millimeter to majestic sequoias with a height of 100 meters, is as astonishing as the figures.
Therefore, negative adaptations will become more common in a population.

Which structure pumps out excess water and wastes?
Answer:
The contractile vacuole pumps out excess water and wastes.
Cells have a particular organelle that pumps out excess water and other wastes from the cell. Contractile vacuole serves this purpose.
The protozoan cell contains an organelle or subcellular structure called the Contractile Vacuole. It is a spherical, transparent, translucent, pulsating single-cell organelle. Previously, it was referred to as a pulsatile or pulsating vacuole. It is encased in a unit membrane, floats in the cytoplasm, and is filled with watery fluid. It is a vacuole that constricts and expels water from the cell, as its name suggests. It frequently stretches and shrinks. While water is expelled from the contractile vacuole as it expands, the contractile vacuole contracts, causing water to collect inside the organelle. The contractile vacuole is the protozoan unicellular organism's kidney. It shows the rhythmic systolic and diastolic movements.
Therefore, Contractile vacuole pumps out excess water & wastes.

why does the detergent and protease enzymes are needed in order to collect pure samples of dna
Answer:
Explanation:
Detergent enzyme used because The positively charged sodium ions in the salt help protect the negatively charged phosphate groups that run along the backbone of the DNA. A detergent is then added. The detergent breaks down the lipids in the cell membrane and nuclei. DNA is released as these membranes are disrupted.
Proteases catalyze the breakdown of contaminating proteins present in the solution to its component amino acids. It also degrades any nucleases and/or enzymes that may be present in the sample. This is of vital importance since these chemical compounds can attack and destroy the nucleic acids in your sample.

Answer: Echidnas: With a keen sense of smell, an echidna uses its long, hairless snout to search for food, detect danger and locate other echidnas. Termites are the preferred food, which is why the animal is often called the 'spiny anteater'. After finding food, an echidna catches the prey with its long, sticky tongue
