What happens when an antigen is introduced into an organism?
A. Myeloma cells are activated.
B. Monoclonal antibodies are produced from plasma cells
C. Polyclonal antibodies are produced from plasma cells.
D. Polyclonal antibodies are produced from somatic cells.

Answers

Answer 1

Answer:

B. Monoclonal antibodies are produced from plasma cells

Explanation:

An antigen is a molecule present on the surface of a pathogenic organism and they are capable of generating an immune response by binding to specific antibodies (immunoglobulins) that are secreted by lymphocytes B cells of the immune system. B cells are a type of white blood cell that plays key roles during humoral immunity of the adaptive immune system. When an antigen is introduced into the organism, a specific lineage of B cells proliferate, in a process known as monoclonal expansion.

A) Sarcoidosis
B) Pneumothorax
C) Hypersensitivity pneumonitis
D) adult respiratory distress syndrome

Answers

Answer: Option B.

Pneumothorax

Explanation:

Pneumothorax occurs when air buildup between the chest wall and the lungs thereby leading to increased pressure in the chest and it inturn decrease the amount of blood that flow back to the heart because the blood find it difficult to force it's way into the chest and the heart. This is cause by injury to the chest, lung danage, rupture air blisters and mechanical ventilation.

However, when Psyche has always been helped make immortal, the power of prayer overcomes everything so that the two main characters can indeed be formed forever.

The cell theory was first proposed in 1838. Evidence obtained through additional scientific investigations resulted in the current cell theory. Which statement describes a component of the original cell theory that was removed because of the new scientific knowledge?

Answers

Answer

The correct answer is option D, that is, cell produce through the spontaneous generation.

Rate me please :):)

It is now recognized that life originates from prior life and that cells originate from preexisting cells as a result of experiments and the discovery of the microscope. Thus, option D is correct.

What is original cell theory?

All living things are made up of one or more cells, which is one of the three principles of the cell theory. The fundamental unit of structure and organization in organisms is the cell.

While doing studies on tissues in the late 1830s, zoologist Theodor Schwann and botanist Matthias Schleiden proposed the united cell theory.

The unified cell theory states that each living thing is composed of one or even more cells, every cell is the basis of life, and new cells can be created from existing cells.

Therefore, cell produce through the spontaneous generation.

The amino acid chain which will be formed by the codons "ACU CCA UCG" will be Threonine-Proline-Serine. Thus, the correct option will be B.

What is amino acid chain?

An amino acid can be defined as the fundamental molecule which serves as the building block for protein molecules in the body. There are about twenty different amino acid molecules present inside the body of an organism. A protein molecule consists of one or more chains of amino acid molecules called as polypeptides whose sequence is encoded in a gene.

Different codons are present in the cell which encodes for different amino acids. A codon is a set of three nucleotides which encode amino acid molecules. ACU codon encode for threonine amino acid, CCA encode for Proline amino acid, and UCG encode for Serine amino acid.

Therefore, the correct option will be B.

Answers

Answer:

Many individuals consider that Archaeopteryx would have been the first bird, however, many paleontologists are against it. The findings of many fossils of Archaeopteryx have revealed that though the creature exhibited wings, the majority of its characteristics were of reptile, like the existence of full teeth set. Apart from this, the wings formation of the creature demonstrated that it was not completely capable of flying.  

No matter what, the presence of wings makes them closely associated with the modern time birds. Thus, it can be concluded that Archaeopteryx could be considered as an intermediate between the reptiles and the birds and is a precursor to the modern-day birds' evolution.

A. One population breeds in spring, the other in fall.
B. Males of the two populations have different flight patterns in courtship.
C. When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch.
D. All of the above is correct.
E. None of the above is correct.

Answers

Answer:

The correct option is D: All of the above is correct.

Explanation:

The biological species concept says that species are population groups that, in a real or potential way, can reproduce among each other and that are reproductively isolated from other groups.

Individuals belonging to a species cannot mate with members of other species, and if they do there is not any reproductive success.    

The mechanisms of reproductive isolation might be divided in prezygotic and postzygotic.

Prezygotic or Premating mechanisms:

Ecological or due to habitat isolationSeasonal or temporal. This is the case described in option A "One population breeds in spring, the other in fall". These species are reproductively isolated because they differ in their breeding season.Sexual or ethological. This is the case described in option B "Males of the two populations have different flight patterns in courtship". Males belonging to each species behave differently during courtship. MechanicalGametes incompatibility

Zygotic or Postmating Mechanisms:

Hybrid inviability. This is the case described in option C which states that "When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch". Eggs fail to hatch because the zygote is inviable. Hybrid sterilityHybrid decreased fertility

The volume of gas gathered can be utilized to find out the rate of photosynthesis and whenever coupled by methods for pH observing gadget, an expansion in pH which shows soluble alkaline means that more oxygen yield. Along these lines, this method can be utilized to then again check CO2 levels. The gas syringe is utilized to permit the oxygen gas bubbles to be gathered at the known for evacuation and estimation purposes.

How do you think pollination takes place in flowering plants?

Answers

Answer:

My answer is down below.

Explanation:

Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species take place. After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begins to grow a tube. This tube is called the pollen tube.

Explanation:

insects typically pollinate flowers as they move from plant to plant searching for food. when an instects lands on a flower to feed, pollen grains sticks to its body. As the instects moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs.

The paranasal sinuses are lined with a membrane that creates mucus during allergies or the common cold. Presence of mucus and swelling of the membranes can cause a "sinus headache." If Regina has a cold and she feels the pain of a sinus headache inferior to her eyes, which bone is housing the affected paranasal sinus?

Answers

Answer:

The maxillary sinus, that is, the sinus located in the upper jaw, would be affected.

Explanation:

Sinusitis is a very traditional disease that is associated with headache, discomfort, and increased mucus making.

The causes can be viral or bacterial or even by some inhaled noxa, sinusitis of this type is bilateral, different from sinusitis of dental cause that are usually unilateral.

The paranasal sinuses are the sinuses that pneumatize the head, that is, they generate an internal air current in the bones to be able to heat and disinfect them from those noxas that are inhaled (that is why they are covered by a ciliated mucosa that drags the noxa to the outside and also its structure is pseostratified with mucous cells that secrete mucus enveloping the noxa).

Another function of the paranasal sinuses is to be able to alleviate the weight of the head, since the shell and the bones that remain in the head formation are very heavy, thus generating these cavities filled with air to alleviate the feeling of "heavy head" "When they become inflamed and filled with mucus, they are obliterated or with a reduced space, so the head feels heavier for some people.

The paranasal sinuses are the maxillary sinuses that are in the upper jaw, the sphenoid sinuses that are in the sphenoid, the ethmoid sinuses that are in the ethmoid and the frontal ones that are in the frontal bone that is vulgarly called as the forehead.
