The chance that a child will have normal skin pigmentation is 3/4. The chance that a child will be albino is 1/4. If the child is normal, the chance that it is a carrier (heterozygous) for the albinism allele is 1/2.

Albinism is caused by a recessive allele, meaning that a person must inherit two copies of the allele in order to display the phenotype. If two heterozygous parents (one dominant allele and one recessive allele) have children, there is a 3/4 chance that the child will inherit the dominant allele and have normal skin pigmentation, and a 1/4 chance that the child will inherit the recessive allele and be albino. If the child has normal skin pigmentation, it is equally likely to have inherited either one dominant allele and one recessive allele or two dominant alleles.

In cellular respiration, oxygen is not broken down to form carbon dioxide and water.

Cellular respiration is the process by which cells convert nutrients into usable energy in the form of ATP (adenosine triphosphate). It involves a series of metabolic reactions that occur within the mitochondria of cells. The process can be divided into three stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation.

During glycolysis, glucose is broken down into pyruvate, which then enters the citric acid cycle. In the citric acid cycle, pyruvate is further broken down, and carbon dioxide is produced. Finally, oxidative phosphorylation uses electron transport chains to generate ATP. Cellular respiration is essential for the survival and functioning of all living organisms.

Muscle cells, also known as muscle fibers, undergo several adaptations that enable them to carry out their functions, which include contractions, generating force, and producing movement. Some of these adaptations include:

1. Hypertrophy: an increase in the size of the muscle fibers, which allows for a greater ability to generate force.

2. Increased number of myofibrils: the contractile units within muscle fibers, which increases the overall contractile ability of the muscle.

3. Increased levels of sarcoplasmic and myofibrillar proteins: these proteins are involved in the contraction process, and their increased levels lead to improved muscle function.

4. Increased levels of enzymes and energy-rich molecules: these help to support the high metabolic demands of muscle contraction.

5. Increased number of mitochondria: the powerhouses of the cell, which help to supply energy to the muscle fibers.

6. Increased capillarization: the development of a greater network of blood vessels, which helps to supply the muscle with oxygen and nutrients, and to remove waste products.

According to the Endosymbiotic theory, Option A) The engulfed cell provided the host cell with adenosine triphosphate (ATP), was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food.

The prevailing evolutionary explanation of the creation of eukaryotic cells from prokaryotic creatures is symbiogenesis (endosymbiotic theory or serial endosymbiotic theory). According to the idea, mitochondria, plastids like chloroplasts, and perhaps other organelles of eukaryotic cells are descended from formerly free-living prokaryotes (more closely related to Bacteria than Archaea) taken one within the other in endosymbiosis. Mitochondria appear to be connected to Rickettsiales bacteria phylogenetically, whilst chloroplasts are thought to be related to cyanobacteria.
