Using the results of his experiments with pea plant crosses, Gregor Mendel discovered: A) the principles of dominance, segregation, and independent assortment.

In this famous experiment, Mendel cross- pollinated pea plants based on their different features to make important discoveries on how traits are inherited between the generations.

Mendel crossed the pure lines of pea plants. Dominant traits, like purple flower color, appeared in first-generation hybrids (F1), whereas recessive traits, like white flower color were masked. But recessive traits reappeared in second-generation (F2) pea plants in ratio of 3:1 (dominant to recessive).

The experiment allowed Mendel to conclude on two laws of Inheritance; that are Law of Segregation and Law of Independent Assortment.

Answer: Duplication of chromosome can cause multiple genes to work in an uncontrolled manner.

Explanation:

There are numerous genes that are encoded by the chromosome. The duplication in the chromosome can cause multiple genes to go out of control that can cause patterning of the body and head which can influence the wing patterning or pigmentation. For example in Down's syndrome the three copies of chromosome number 21 are formed which is the trisomy of chromosome number 21 which can cause developmental issues in humans symptoms are flattened face, short neck, small ears, and others.

The researcher who conducted an investigation on a blood disease carried by birds found out that the organism is unicellular and has a nucleus, cell wall, and the ability to produce spores. Based on this information, the organism belongs to the Kingdom Fungi.

The kingdom Fungi consists of unicellular and multicellular organisms that lack chlorophyll and reproduce asexually and sexually by forming spores. They are heterotrophic organisms, which means they depend on other organisms for their food. Fungi cells have a cell wall made up of chitin, which provides strength and rigidity to the cell wall. The cytoplasm of the fungal cells contains many specialized organelles, including nuclei, ribosomes, mitochondria, and Golgi bodies that carry out various metabolic activities.

The researcher's findings suggest that the organism is a unicellular fungus with a nucleus, cell wall, and the ability to produce spores. Spores play a crucial role in the fungal life cycle, as they allow the organism to reproduce and spread to new habitats. These spores can be transported by wind, water, or other organisms to colonize new areas.

Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.

3 answer is actually true i guess.

Explanation:

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

How is DNA replicated?:

Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

What triggers replication?

A schematic shows a double-stranded DNA molecule undergoing the replication process. The left side of the molecule is double-stranded. In the middle of the molecule, a globular yellow structure, representing the protein helicase, is bound to the ends of several nitrogenous bases on the lower strand. To the right of the helicase protein, the double helix has opened and the top strand has separated from the bottom. At right, a short segment of the newly replicated double-stranded DNA molecule is visible.

Helicase (yellow) unwinds the double helix.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands. As the helicase moves along the DNA molecule, it continues breaking these hydrogen bonds and separating the two polynucleotide chains.

A schematic shows a double-stranded DNA molecule undergoing the replication process. At right, the double helix has opened and the top strand has separated from the bottom. A globular yellow structure, representing the protein helicase, is bound to the ends of several nitrogenous bases on the lower strand. A red globular molecule, representing the enzyme primase, is bound to the lower DNA strand to the right of helicase.

While helicase and the initiator protein (not shown) separate the two polynucleotide chains, primase (red) assembles a primer. This primer permits the next step in the replication process.

Meanwhile, as the helicase separates the strands, another enzyme called primase briefly attaches to each strand and assembles a foundation at which replication can begin. This foundation is a short stretch of nucleotides called a prime

The oxygen pulls the electrons more than the hydrogens

The shortest DNA strand in the DNA sample from the Gel Electrophoresis lab activity on the Learn. Genetics website is approximately 1500 base pairs (bp) in size. So, option D is correct.

During the Gel Electrophoresis lab activity, DNA samples of different sizes were loaded onto the gel. Gel Electrophoresis separates DNA fragments based on their size, with smaller fragments moving faster and traveling farther on the gel. By comparing the migration distance of the DNA sample to known DNA markers of known sizes, we can estimate the size of the DNA fragment. In this case, the shortest DNA fragment observed in the activity corresponds to approximately 1500 base pairs (bp) in size.
