The purpose of adding hydrogen peroxide to the uninoculated tube is to serve as a negative control. In microbiology, negative controls are used to ensure that any observed results are not due to contamination or external factors.

Hydrogen peroxide is added to the uninoculated tube as a substrate for the enzyme catalase, which is produced by many bacteria. Catalase catalyzes the breakdown of hydrogen peroxide into water and oxygen. If there is no bacterial contamination in the tube, no catalase enzyme will be present, and no reaction will occur.

By including a negative control, any observed reaction in the other tubes containing bacterial samples can be compared to the uninoculated tube. If a reaction occurs in the bacterial tubes but not in the uninoculated tube, it suggests that the observed reaction is due to the presence of catalase-producing bacteria.

This helps confirm the presence of the desired microbial activity in the experiment and rules out any false positive results.

Based on the phenotypes and genotypes of the offspring, it is clear that the purple flower color allele is dominant over the white flower color allele.

The Punnett square is a diagram used to predict the outcome of a cross between two individuals. In this particular case, the Punnett square illustrates a cross for the color of the flower. The genotypes of the parents are represented by the letters P and p, where P represents the dominant allele for purple flower color and p represents the recessive allele for white flower color.
The Punnett square predicts that the offspring will have either a genotype of PP, Pp or pp, with PP representing homozygous dominant for purple flower color, Pp representing heterozygous for purple flower color and pp representing homozygous recessive for white flower color. The phenotypes of the offspring are represented by the physical appearance of the flower.
This is because some of the offspring have purple flowers despite having one copy of the recessive allele (Pp genotype). The parents are therefore likely to be heterozygous (Pp) for flower color, as this would allow for the expression of both purple and white flower colors in the offspring.

Transportation is the movement of substances from one place to another, including water, nutrients, waste material, and excretory products.

In biology, the term "transport" describes the action of moving a particle or ion across a cell barrier or through the circulation. In this respect, there are two different kinds of transportation: passive transportation and active transportation. An area of greater concentration is moved to an area of lower concentration through the process of passive transport, which involves the movement of ions or molecules along a concentration gradient.

Passive movement can be divided into four main categories: diffusion, assisted diffusion, filtration, and osmosis. Ions or molecules travel in opposition to a concentration gradient during active transport.

Solution:

In the oceans, the primary producers are above all algae, which form phytoplankton. Phytoplankton is essential in the production of oxygen. In fact, more than 50 percent of the oxygen on our planet is produced in the sea through photosynthesis triggered by phytoplankton, an autotrophic microorganism that is essential for life on the planet.

Now, if iron is a fundamental nutrient for phytoplankton and scientists are working to make this nutrient more available for this photosynthetic microorganism, which can use carbon dioxide and generate oxygen in exchange, this is because they want to establish a reduction of the greenhouse gas carbon dioxide in the atmosphere.

So that, we can conclude that the correct answer is:

Reduction of the greenhouse gas carbon dioxide in the atmosphere.

Human herpesvirus 4, also known as Epstein-Barr virus (EBV), becomes latent in B lymphocytes. Epstein-Barr virus (EBV) is a human herpesvirus with a double-stranded DNA genome that causes infectious mononucleosis (IM), also known as glandular fever or the "kissing disease." Therefore, option A is the correct answer.

EBV infection also causes a variety of other diseases, including lymphomas and nasopharyngeal carcinoma, particularly in immunocompromised individuals.The Epstein-Barr virus (EBV) is a virus that is part of the herpesvirus family. It primarily infects B lymphocytes, causing infectious mononucleosis. B-lymphocytes are a type of white blood cell, also known as B-cells, that are in charge of generating antibodies to fight infections. Latency is when the virus is in a resting phase within a host cell, waiting for a cue to reactivate and start producing new virus particles.

EBV can remain in a latent state in B lymphocytes for a long period of time, and it can become reactivated, causing new infections or symptoms.

Answer:

RNA is single standard while DNA is double standard

RNA contains the sugar ribose, while DNA contains deoxyribose.

RNA contains uracil, while DNA contains thymine.

RNA can leave the nucleus, while DNA cannot.

Explanation:

RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.

DNA stands for deoxyribonucleic acid which is defined as a double-stranded molecule consisting of a long chain of nucleotides whereas RNA stands for ribonucleic acid which is defined as a single-stranded molecule consisting of a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating but RNA does not replicate on its own.

The base pairing is of DNA is as follows: GC (Guanine pairs with Cytosine) A-T (Adenine pairs with Thymine) while the base pairing of RNA is as follows: GC (Guanine pairs with Cytosine) A-U (Adenine pairs with Uracil). RNA has the sugar ribose while DNA has the sugar deoxyribose. DNA is located in the nucleus of a cell and in the mitochondria while the RNA is found in the cytoplasm, nucleus and in the ribosome.

Thus, RNA is a single-stranded structure while DNA is a double-stranded structure while the former containing the uracil base and the latter containing the thymine base.
