Answer:

Rotavirus

Explanation:

I assume your answer choices are:

Giardia organisms

Shigella organisms

Rotavirus

Salmonella organisms

A viral pathogen is a pathogen caused by a virus.

Therefore It is not Giardia or Salmonella because both are bacterial pathogens, not viral.

And it is not Shigella because Shigella is uncommon.

Homologous structures are present in many different species that share a common ancestor. the structure are anatomically similar and persist in the different species.

This is evident of divergent evolution because it shows that different animals come from a common ancestor but evolve o become different species from each other.

Answer:

The correct sequence is:III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.

II) Lymphocytes secrete antibodies.

I) Pathogen is destroyed.

V) Only memory cells remain.

Explanation:

Effective resistance against infection is essential for the development and functioning of the mammalian organism, and for it to be effective, multiple defense systems must be available. In order to meet these objectives, the body has developed a complex system of overlapping and interrelated defense mechanisms, which together can destroy or control almost all invaders.III) Antigenic determinants from pathogen bind to antigen receptors on lymphocytes. It consists of the binding of the foreign antigen to the specific receptors existing on the membrane of mature lymphocytes. The B lymphocytes that mediate humoral immunity express antibody molecules on their surface, which bind to foreign proteins, polysaccharides or lipids in their soluble form; T lymphocytes, responsible for cellular immunity, express so-called T cell receptors (TCR), which recognize small sequences of antigenic peptides.

IV) Lymphocytes specific to antigenic determinants from pathogen become numerous.II) Lymphocytes secrete antibodies.

Activation phase: sequence of events that occur in lymphocytes as a result of specific antigen recognition. All lymphocytes undergo two fundamental changes: a) proliferation: expansion of antigen-specific clones and amplification of the protective response, in which the CD4 T lymphocyte, capable of activating CD8 B and T lymphocytes, assumes a preponderant role; b) differentiation: stage in which effector cells and memory cells are formed. The first produce various substances that can interact with the antigen, such as antibodies and lymphokines; the second are partially differentiated lymphocytes, that is, they do not become effector cells.

I) Pathogen is destroyed.

In this phase, the T lymphocytes differentiated into effector cells migrate to the sites of attack, where they carry out their functions of eliminating pathogens, while the B lymphocytes perform them in the peripheral organs themselves.

V) Only memory cells remain.

One of the most important consequences of the adaptive immune response is the establishment of the state of immunological memory, which lies in the ability of the immune system to respond more quickly and efficiently to microorganisms that have previously infected the host and it reflects the preexistence of a clonally expanded population of antigen-specific lymphocytes. We call, therefore, the immune response that the organism gives when it comes into contact for the first time with a foreign agent and from which a series of events derives that include nonspecific innate defense mechanisms and adaptive response mechanisms, if the pathogen manages to survive the first ones.

Answer:

Explanation:

Cell transport refers to the movement of substances across the cell membrane. Probably the most important feature of a cell's phospholipid membranes is that they are selectively permeable. A membrane that is selectively permeable, or semipermeable, has control over what molecules or ions can enter or leave the cell, as shown in Figure below. This feature allows a cell to control the transport of materials, as dictated by the cell's function. The permeability of a membrane is dependent on the organization and characteristics of the membrane lipids and proteins. In this way, cell membranes help maintain a state of homeostasis within cells (and tissues, organs, and organ systems) so that an organism can stay alive and healthy.

A repressible operon is a type of operon in which gene expression is normally active but can be repressed or inhibited in the presence of a specific molecule. This type of operon is commonly found in bacterial cells and is involved in the regulation of metabolic pathways.

In a repressible operon, a repressor protein binds to the operator region of the operon, preventing the transcription of the genes. However, in the presence of a specific molecule, called a corepressor, the repressor protein is able to bind to the operator, inhibiting gene expression. An example of a repressible operon is the trp operon, which is involved in the biosynthesis of the amino acid tryptophan. When tryptophan levels are high, the trp repressor binds to the operator, preventing the transcription of the genes required for tryptophan synthesis.

In summary, a repressible operon is a type of operon that is normally active but can be inhibited in the presence of a specific molecule. It plays an important role in the regulation of metabolic pathways in bacterial cells.

The most probable conclusion about the evolution of legless lizards is option c - They had ancestors with four limbs, but they lost this trait during evolution.

During the process of evolution, legless lizards have lost their limbs over a long period of time. Their ancestors were originally quadrupedal lizards, but through natural selection and adaptation, the legless form became more advantageous. Legless lizards have a greater ability to burrow underground, which provides them with benefits such as protection and access to prey. As a result, the trait for limblessness became desirable and advantageous in their environment.

Over time, lizards with shorter limbs or no limbs at all were more likely to survive and reproduce, passing on the trait for limblessness to their offspring. This gradual process of natural selection and inheritance led to the evolution of legless lizards as a distinct group with specialized adaptations for their burrowing lifestyle.

Energy is  necessary for a bond to form in a chemical compound. Therefore, option (C) is correct.

Bond formation in a chemical molecule requires energy. The formation of chemical bonds is the result of electron sharing or transfer between atoms or molecules. Electrostatic repulsion between charged particles makes this process energy-intensive.

Heat, light, and electricity are all examples of kinds of energy that may be delivered. Atoms or molecules can undergo chemical reactions—the building of new bonds and the development of a stable compound—when given the appropriate amount of energy.

The antagonist is the quadriceps. The quadriceps contract to extend the knee during the contact and recovery phase, while the hamstrings lengthen to allow movement.

Is the hamstring stretch antagonistic or agonistic?

When the knee extends, the hamstrings stretch, as well as the antagonists of this activity. When the knee bends, the hamstrings become the agonist muscle, and the quadriceps now become the antagonist.

The three hamstring muscles are as follows: Biceps femoris, located on the outside of your body. This hamstring's function is to flex your knee, extend your thigh at your hip, and rotate your lower leg from side to side when your knee is bent.

Therefore, In complex movements, muscles that are antagonists to the hamstrings are the quadriceps.

The parasitic anaerobic amoebozoan Entamoeba histolytica belongs to the genus Entamoeba. E. histolytica, which mostly infects humans and other primates and causes amoebiasis, is thought to infect between 35 and 50 million individuals globally. It is believed that E. histolytica infections cause more than 55,000 fatalities annually. Prior to the discovery that at least 90% of these illnesses were caused by a second species, E. dispar, it was believed that 10% of the world's population was affected. Although animals like dogs and cats can briefly contract the disease, it is not believed that they significantly contribute to its spread.

The skeleton(hipbones) starts off with more separate bones and fuses them along the life span to allow for complete development of underlying organs and for flexibility needed during the birth of the developing foetus. This flexibility is the advantage of the unfused bone before birth.

Skeleton is defined as the hard structures that makes up the musculoskeletal system specific f the body which provides support and ability for movement.

During the development of the foetus, not all the bones of the body are fused especially the bones of the skull and the bones of the hip. This leads to the total number of bones in a baby being 300 bones and that of an adult is 206.

After birth, the bones of an infant undergoes ossification. That is to say that the skull and hip bones which where separate before birth fuses together and forms a stronger structure.

Answer:

The correct answer is B. "Melanocytes and muscle cells express different genes."

Although all cells in an organism (such as a human) contain the same DNA, different cell types express different sets of genes. Gene expression is the process by which specific genes are activated to produce a needed protein. In this case, the gene responsible for melanin production is expressed in melanocytes, but not in muscle cells.

This does not mean that muscle cells have destroyed the gene for melanin (as stated in option C) or that melanocytes contain different genes from muscle cells (as stated in option D). All cells within an organism contain the same genes, but not all genes are expressed in every cell. The process of gene expression is regulated by the cell to ensure that each cell type functions properly.

Option A is also incorrect because all cells, including both muscle cells and melanocytes, rely on both DNA (for storing genetic information) and RNA (for transmitting that information and producing proteins). DNA is transcribed into RNA, which is then translated into proteins. This process occurs in all cells.

The statement explains the difference between skin melanocytes and muscle cells is - melanocytes and muscle cells express different genes. So option b  is correct.

Melanocytes are dark, dendritic-shaped, highly differentiated cells that secrete melanin, a pigment found in melanosomes, which is the primary function of melanocytes.

Melanocytes are a type of cell derived from the neural crest. They form a synapse with keratinocytes through their dendrites in the epidermis. Melanocytes play an important part in skin pigmentation and their role in the generation and distribution of melanin has been extensively studied.
