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.

Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).

Explanation:

Datos disponibles:

Podemos nombrar el alelo dominante para color naranja N, y al alelo recesivo  para color gris n.

Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.

Supongamos que uno de los parentales lleva el genotipo Nn, y el otro parental es nn.

Cruce:

Parental)      Nn    x     nn

Gametas)   N    n       n    n

Fenotipos) Naranja     Gris

Cuadro de Punnett)      N           n

                            n       Nn         nn

                            n       Nn         nn

F1)  2/4 = 1/2 = 50% de la progenie tendrá genotipo heterocigoto, Nn

     2/4 = 1/2 = 50% de la progenie tendrá genotipo homocigota recesivo,    

     nn

     50% de la progenie será color naranja (Nn)

Excessive subtalar pronation may cause lateral knee abduction (varus) and forefoot supination. Hence, a and b are the correct options.

Excessive subtalar pronation refers to an excessive inward rolling motion of the foot at the subtalar joint during the gait cycle. This abnormal movement can lead to various biomechanical changes and potentially cause different issues in the lower extremities.

One of the consequences of excessive subtalar pronation is lateral knee abduction (varus). As the foot excessively pronates, it causes the lower leg and knee to rotate inward, resulting in a misalignment of the knee joint. This misalignment can lead to increased stress on the lateral (outer) side of the knee, potentially causing pain and discomfort.

Another effect of excessive subtalar pronation is forefoot supination. As the foot excessively pronates and rolls inward, the forefoot tends to shift into a supinated position, meaning it rolls outward. This can lead to an uneven distribution of weight and pressure on the foot, potentially causing issues such as arch pain, plantar fasciitis, and instability during walking or running.

It's important to note that excessive subtalar pronation can have varying effects on individuals, and the specific consequences may differ based on factors such as foot structure, muscle imbalances, and activity levels. Proper diagnosis and management, including orthotic devices, footwear modifications, and exercises, can help address these issues and reduce symptoms associated with excessive subtalar pronation.

THE STRESS RESPONSE. Increased concentrations of cortisol, glucagon, and epinephrine serve to increase blood glucose levels and to redirect metabolism so as to increase concentrations of fuel substrates. Finally, there appears to be a tendency towards hypercoagulability, which would likely improve hemostasis.

Explanation:

Dose this help you?

As a result of the general stress response, blood concentrations of epinephrine and cortisol rise.

When the body is under stress, the hormone cortisol, stress and steroid, is released. As a result, the body's sugar level rises, and the extra sugar aids in tissue healing.

Adrenaline is another name for epinephrine. It is a hormone used in medication. When the body experiences an emergency, this is released. When something unexpected happens, like getting stung or bitten by a dog, taking medicine, etc.

They come with charges that include faster heartbeats, higher blood sugar, and improved accuracy.

Therefore, blood concentrations of epinephrine and cortisol increase during the stress response.

While traditionally considered a commensal relationship, the interaction between humans and their microbiome is more appropriately termed a mutualistic relationship.

A mutualistic relationship is a type of symbiotic relationship in which both the host (in this case, the human) and the microbiome benefit from the interaction.

The human microbiome is composed of trillions of microorganisms, including bacteria, viruses, fungi, and archaea, that live on and within the human body. These microorganisms play important roles in human health, such as aiding in digestion, regulating the immune system, and producing essential vitamins and other compounds.

In turn, the human body provides a habitat and nutrients for these microorganisms to thrive. Without the microbiome, the human body would not be able to function properly, and the microbiome would not be able to survive.

Therefore, the interaction between humans and their microbiome is more than just a commensal relationship, where one organism benefits and the other is unaffected. It is a mutually beneficial relationship where both the host and the microbiome depend on each other for survival and well-being.

You are performing a cross of garden pea plants of two different seed textures (round and wrinkled). Round is dominant over wrinkled. If you start with true breeding parents in the P generation, you would most likely see in the F2 generation 750 round 250 wrinkled.

A true-breeding plant is one that produces offspring with the same phenotype when it self-pollinates or crosses with another true-breeding plant for several generations. The true-breeding parents for round and wrinkled seeds would be RR and rr, respectively. All the F1 progeny would be heterozygous Rr, according to the laws of Mendelian inheritance, where R is dominant and r is recessive.

The gametes of the F1 plants will have the alleles R and r. When the F1 plants are self-crossed, four possible genotypes are possible: RR, Rr, rR, and rr. Round and wrinkled seeds will be produced by both RR and Rr genotypes, while only wrinkled seeds will be produced by the rr genotype.Therefore, in the F2 generation, we will get 3 round and 1 wrinkled. 750 Round and 250 wrinkled is the ratio of this generation.

'Chemosynthesis' basically is the process which a bacteria living near a heat vent on the ocean floor use to build carbon-based molecules, such as sugars.

What do you mean by Chemosynthesis?

Chemosynthesis is a process by which some organisms use chemical energy to produce carbohydrates. This process occurs in environments where sunlight is not available, such as deep-sea hydrothermal vents. Organisms such as bacteria and other microbes convert chemicals such as hydrogen sulfide and methane into energy, which they use to produce organic molecules such as glucose.

The bacteria living near hydrothermal vents on the ocean floor use chemosynthesis to build carbon-based molecules, such as sugars, from the hydrogen sulfide and other chemicals that are spewed from the vent. The bacteria use the energy from the chemical reaction to form carbohydrates from the chemical reaction, which are then used as a source of energy for the bacteria. This process is thought to be the first form of energy production for life on Earth, and is seen as an important part of the global carbon cycle.
