It seems that you have provided a series of statements about the genotypes of different individuals at two genetic loci, the b locus and the d locus. Each genetic locus can have two alleles, and the combination of alleles present in an individual's genotype determines their physical and behavioral traits.
What is genotype?Genotype refers to the genetic makeup of an individual, specifically the set of alleles that an individual carries for a particular trait or traits. An allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same location on a chromosome. Each individual has two copies of each gene, one inherited from each parent, and thus can have two copies of the same allele or two different alleles.
Here,
Based on the information provided, we can make some observations: At the b locus, both parents were bb. This means that both parents had two copies of the recessive b allele, and all of their offspring will inherit one b allele from each parent, resulting in a genotype of bb.
At the d locus, one parent was dd and the other was dd. This means that both parents had two copies of the recessive d allele, and all of their offspring will inherit one d allele from each parent, resulting in a genotype of dd.
At the b locus, one parent was bb and the other parent could have had any genotype (bb, Bb, or BB). This means that one parent had two copies of the recessive b allele (bb), and the other parent could have had two copies of the recessive b allele (bb), one copy of the recessive b allele and one copy of the dominant B allele (Bb), or two copies of the dominant B allele (BB). The genotype of the offspring will depend on the genotype of the other parent.
At the d locus, both parents were dd. This means that both parents had two copies of the recessive d allele, and all of their offspring will inherit one d allele from each parent, resulting in a genotype of dd.
The other statements simply repeat some of the information provided earlier, so we can make the same observations as above.
It's worth noting that we can't make any predictions about the physical or behavioral traits of the individuals based solely on their genotypes at these two loci, since we don't know which genes are associated with which traits.

that Rosalind Franklin was absolutely robbed of the Nobel Prize
Rosalind Franklin was an important and influential scientist who made significant contributions to the field of molecular biology.
The idea that she was "robbed" of the Nobel Prize is not entirely true. Her work on X-ray crystallography helped determine the structure of DNA, but was not the only factor in her discovery. Up to three Nobel Prizes have been awarded to James Watson, Francis Crick and Maurice Wilkins for their contributions to the discovery of the structure of DNA.
It's important to recognize that the scientific community is collaborative and no one person can be responsible for discoveries. Franklin's work was certainly worthwhile, but she wasn't the only scientist working on the problem. Watson, Crick, and Wilkins all made important contributions to the discovery of DNA structure. Furthermore, Franklin's premature death in 1958 prevented her from winning the Nobel Prize, even if she did.
Ultimately, although Franklin's contribution to the discovery of her DNA structure was significant, it would be inaccurate to say that she was "robbed" of the Nobel Prize. She said the prize was given to the scientist who led to her discovery, but unfortunately Franklin didn't live to win the prize, even though she did. It is important to recognize the contributions of all the scientists involved in the discovery, rather than just evaluating one scientist.

put the following in order. beginning with the lungs and including all valves, identify the path that blood flows into the heart, out to the body, and returned to the heart.
The order is: lungs → right atrium → tricuspid valve → right ventricle → pulmonary valve → pulmonary artery → lungs (for gas exchange) → pulmonary veins → left atrium → mitral valve → left ventricle → aortic valve → aorta → body → superior and inferior vena cava → right atrium.
What is blood flows?
Blood flow refers to the movement of blood through the circulatory system, which includes the heart, blood vessels, and the organs and tissues that receive blood. Blood flow is critical for the proper functioning of the body, as it delivers oxygen and nutrients to cells and removes waste products like carbon dioxide. Blood flows as a result of the pumping action of the heart, which creates pressure that drives the movement of blood through the arteries, capillaries, and veins.
Blood flows into the heart, out to the body, and returned to the heart:
Blood enters the right atrium of the heart from the body via the superior and inferior vena cava.The right atrium contracts, pumping blood through the tricuspid valve into the right ventricle.The right ventricle contracts, pumping blood through the pulmonary valve into the pulmonary artery.The pulmonary artery carries the blood to the lungs, where it picks up oxygen and releases carbon dioxide.Oxygenated blood returns to the heart via the pulmonary veins, entering the left atrium.The left atrium contracts, pumping blood through the mitral valve into the left ventricle.The left ventricle contracts, pumping blood through the aortic valve into the aorta.The aorta carries the oxygenated blood to the rest of the body, delivering nutrients and oxygen to cells and tissues.Deoxygenated blood returns to the heart via the superior and inferior vena cava, and the cycle starts again.So the order is: lungs → right atrium → tricuspid valve → right ventricle → pulmonary valve → pulmonary artery → lungs (for gas exchange) → pulmonary veins → left atrium → mitral valve → left ventricle → aortic valve → aorta → body → superior and inferior vena cava → right atrium.

The activity of the promoter that controls the expression of the lac operon is regulated by two different proteins. One of the proteins prevents the RNA polymerase from transcribing, the other enhances the binding of RNA polymerase to the promoter.

what is the difference in number of chromosomes and process used to make the cell between liver and sperm?
Answer:
Explanation:
The liver and sperm are two very different types of cells, with different numbers of chromosomes and processes used to make them.
The liver is a type of somatic cell, which means it is a non-reproductive cell that makes up the tissues and organs of the body. Somatic cells in humans have 46 chromosomes, which come in 23 pairs. Each pair contains two similar but not identical chromosomes, with one inherited from each parent. The process of making somatic cells is called mitosis, which is a type of cell division that produces two identical daughter cells from one parent cell. Mitosis is responsible for growth, repair, and maintenance of the body's tissues and organs.
On the other hand, sperm is a type of germ cell, which is a reproductive cell used for sexual reproduction. Germ cells have half the number of chromosomes as somatic cells, because they must combine with a partner's germ cell during fertilization to create a new organism with the full complement of chromosomes. In humans, sperm cells have 23 chromosomes and are haploid. The process of making germ cells is called meiosis, which is a type of cell division that produces four daughter cells, each with half the number of chromosomes as the parent cell. Meiosis is responsible for the production of sperm and eggs, and is essential for sexual reproduction.
So, in summary, the liver and sperm differ in the number of chromosomes and the process used to make the cells. Liver cells are somatic cells with 46 chromosomes produced by mitosis, while sperm cells are haploid germ cells with 23 chromosomes produced by meiosis.
