One possible explanation is that the inoculation was contaminated with another microorganism that is inhibiting the growth of E. coli.

Another possibility is that the sterilization process was not effective and the broth still contains contaminants that are preventing E. coli growth. Additionally, the incubation temperature of 37 degrees Celsius may not be suitable for E. coli and the bacteria are not able to grow and reproduce effectively in this environment. It's also possible that the E. coli strain used in the inoculation is not viable and is unable to grow and multiply in the broth. To resolve this issue, it's important to carefully control the sterilization process and to choose the appropriate temperature and incubation conditions for the bacteria being studied.

Answer:

The correct answer is D

Explanation:

The cells that form from the first few divisions of a fertilized egg cell can develop into any cell in the human body or the placenta is pluripotent cell. The correct option is B.

Stem cells are the raw materials of the body, the cells that give rise to all other cells with specific responsibilities.

Under the right conditions, stem cells divide to form more cells known as daughter cells in the body or in a laboratory.

Stem cells spawn additional cells for the body as it grows and replace damaged or lost specialized cells.

They are able to do this due to two distinct properties: they can divide repeatedly to produce new cells. They can change into the other types of cells that make up the body as they divide.

Pluripotent cells are those that form from the first few divisions of a fertilized egg cell and can develop into any cell in the human body or the placenta.

Thus, the correct option is B.

The trend that is evident is: Initially, there seems to be support for Mel's hypothesis, but the gold data is not consistent with the predicted trend.

Option C is correct.

The data for zinc, nickel, copper, and silver shows that as the density increases, the melting point tends to increase.

From the data we can see , the data for gold does not follow this trend, as its density is lower than silver but its melting point is higher.

Therefore, while there is some initial support for Mel's hypothesis, the inconsistency with gold indicates  that the relationship between density and melting point is not solely determined by density.

Mutations that involve DNA coding to amino acids occur during the process of transcription and translation.

A mutation is a permanent change in the DNA sequence that makes up a gene. Mutations can occur spontaneously, or they can be caused by exposure to certain environmental factors, such as radiation or chemical mutagens. Mutations can be beneficial, harmful, or have no effect on the organism, depending on the nature and location of the change in the DNA sequence.

Mutations can result in the creation of new traits or the loss of existing traits, and they play an important role in evolution. Some mutations can lead to genetic disorders or diseases, while others can have no effect on the organism. Mutations can also be passed down from generation to generation, making them an important factor in the inheritance of traits and the evolution of species.

Answer: Fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, meiosis produces sex cells that will participate in fertilization.

Explanation:

Incomplete questions, options are:

Meiotic cell division occurs as the zygote develops into a gamete, meiosis produce the sex cells that will participate in fertilization, a baby grows into an adult through uncountable meiotic divisions, fertilization occurs, a zygote undergoes mitosis, a baby's cells divide mitotically, mitosis produces gametes.

1. Fertilization occurs: Fertilization is the union of a human egg and sperm (male and female gametes), which usually occurs in the fallopian tube. The result is the formation of a zygote or fertilized egg, which initiates the development of the embryo. In this way, the genetic material of both gametes is also fused.

2. A zygote undergoes mitosis: The zygote is the union of the egg and the sperm. Each gamete contributes 23 chromosomes to form the genetic material of the future organism. The zygote starts to divide throught mitosis. Mitosis is a type of cell division that generates two genetically identical daughter cells and occurs in somatic cells (all cells in the body that are not gametes). Eventually, it divides into two blastomeres, then into 4, then into 8, and so on during the passage of the zygote along the fallopian tube towards the uterus. Subsequent divisions of the 12 cells give rise to the morula. Then, the blastocyst is generated, which is an embryo of between 5-7 days of development and is composed of a large number of cells that begin to differentiate.

3. A baby's cells divide mitotically: An embryo is a living being in the early stages of its development, from fertilization until the organism acquires the morphological characteristics of the species. In the specific case of the human being, the term applies until the eighth week after conception (fertilization). Cell divisions for development occur by mitosis. In this way, the embryo will grow and develop, forming tissues and organs through growth thanks to mitotic divisions.

4. Meiosis produces sex cells that will participate in fertilization: Meiosis is a type of cell division that occurs in the gonads for the production of gametes, whereby a diploid cell undergoes two cell divisions, that generates four haploid cells. Thus sperm and oocytes are produced to eventually fuse during reproduction to form a diploid zygote. Meiosis has certain differences from mitosis, since in this type of cell division, the daughter cells created are all genetically distinct from each other and from the parent cell. This is because a crossing over occurs between non-sister chromatids of homologous chromosomes to exchange genetic material. This ensures that each gamete produced has genetic variability.

If purple-flowered  plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first  generation of offspring should have 100% purple flowers.

Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.

In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.
