The highlighted structure is called Olfactory bulb and it is proportionally smaller in human compared to the similar structure in the sheep brain.

The neuronal component of the vertebrate forebrain responsible for olfaction, or the sense of smell, is known as the olfactory bulb (Latin: bulbus olfactorius). It delivers olfactory data to the amygdala, orbitofrontal cortex (OFC), and hippocampus for further processing, where it plays a role in emotion, memory, and learning. The main olfactory bulb and the accessory olfactory bulb are two separate components that make up the bulb.

The statement that best describes antigenic variation of a parasite is: a) Parasites can change their antigens or create novel antigens.

Antigenic variation refers to the ability of parasites to change their antigens or create new ones. This process is essential for the survival and evasion of the immune system by the parasite. By altering their antigens, parasites can avoid detection and clearance by the host's immune response.

Parasites have evolved sophisticated mechanisms to undergo antigenic variation. They can modify the surface proteins or switch between different antigenic variants. This variation can occur through genetic recombination, gene duplication, or mutation, allowing the parasite to constantly present a different antigenic profile to the immune system.

The ability of parasites to change their antigens or generate novel antigens poses a significant challenge in the development of effective vaccines and treatments. Since the antigens expressed by the parasite can change over time, the immune system may struggle to mount a targeted and long-lasting immune response.

Understanding antigenic variation is crucial in the study of parasitic infections and the development of strategies to control and treat them. By targeting conserved antigens or finding ways to disrupt the antigenic variation mechanisms, researchers aim to develop interventions that can effectively combat parasitic diseases.

Answer:

The primary mechanism by which a cell gets rid of excess carbon dioxide (CO2) is through a process called respiration or cellular respiration. In cellular respiration, cells break down glucose and other organic molecules in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate), along with carbon dioxide and water as byproducts.

Once carbon dioxide is generated during cellular respiration, it diffuses out of the cell and into the surrounding tissues and fluids. From there, it enters the bloodstream and is transported to the lungs. In the lungs, carbon dioxide is exchanged for oxygen through the process of gas exchange during breathing. Oxygen is taken up by the red blood cells, while carbon dioxide is released into the air as we exhale.

In summary, cells eliminate excess carbon dioxide by releasing it into the bloodstream, where it eventually reaches the lungs for exhalation.

The main measure that must be taken to alleviate this situation is the proper disposal of garbage in the community in which Dino lives.

Explanation:

Inadequate disposal of garbage can cause a series of very serious illnesses and accidents to the entire community, which reinforces the need for all residents of a community to promote the proper disposal of waste. This is not happening in the community where Dino and his family live.

The inadequate disposal of garbage can contaminate the water and food of the community, causing diarrhea in Dino. This garbage also caused the accumulation of standing water, allowing the dengue mosquito to develop and infect his sister. In addition, garbage has created a suitable environment for maleficent microorganisms, such as the bacteria that causes tuberculosis.

Angiotensin-converting enzyme is found only in the kidneys and converts angiotensinogen to angiotensin is False.

Angiotensin-converting enzyme (ACE) is found in various organs including the kidneys, lungs, and blood vessels, and converts angiotensin I to angiotensin II.

Angiotensin-converting enzyme (ACE) is not found only in the kidneys. ACE is an enzyme that is widely distributed throughout the body, including various tissues and organs, not just the kidneys.ACE plays a crucial role in the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure, fluid balance, and electrolyte levels in the body. One of the important functions of ACE is the conversion of angiotensin I to angiotensin II.

While the kidneys do contain a significant amount of ACE, it is also present in other tissues such as the lungs, heart, blood vessels, and the gastrointestinal tract. In fact, the lungs are known to have a particularly high concentration of ACE.The widespread distribution of ACE allows for the local production of angiotensin II in different tissues, contributing to the regulation of various physiological processes beyond just kidney function.

Angiotensin-converting enzyme (ACE) is not exclusively found in the kidneys. It is present in multiple tissues and organs throughout the body, serving important roles in the renin-angiotensin-aldosterone system and regulating various physiological processes beyond kidney function.

Answer: Primary producer > primary consumer > secondary consumer > tertionary consumer.

Explanation: Primary producers(plants) get their energy from the sun then when a primary consumer (organism that eats plants; herbivores) eats the primary producer it collects that energy with it. Then when the primary producer is eaten by the secondary producer( carnivores that eat smaller animals; such as wolves,crow,hawks etc.). The tertionary consumer eats the secondary consumer.(tertionary consumers are larger carnivores) therefore energy gets passed down the line all the way to the tertionary consumer.

Answer: The energy flow is unidirectional in nature.

Explanation: When these herbivores are ingested by carnivores of the first order (secondary consumers) further degradation will occur. Finally, when tertiary consumers consume the carnivores, energy will again be degraded. Moreover, in a food chain, the energy flow follows the 10 percent law.

Pyrethroid insecticides prevent the voltage-gated sodium channels of insects from inactivating. Neurons that were exposed to pyrethroids would hyperpolarize.

Pyrethroid insecticides are a group of synthetic chemicals that mimic the structure and activity of natural pyrethrins found in chrysanthemum flowers. These insecticides act on the voltage-gated sodium channels of insects, preventing them from inactivating. This leads to a prolonged opening of the sodium channels, causing an influx of sodium ions into the neurons.

When neurons are exposed to pyrethroids, they hyperpolarize. Hyperpolarization is the process where the membrane potential of a neuron becomes more negative, moving further away from the threshold for generating an action potential. The continuous influx of sodium ions due to the prolonged opening of the sodium channels causes an excessive depolarization of the neuronal membrane, which in turn results in the hyperpolarization of the neuron.

This hyperpolarization prevents the neurons from firing action potentials properly, disrupting the normal communication between nerve cells. Consequently, this disruption affects the insect's nervous system, causing paralysis and eventually leading to the insect's death. Pyrethroid insecticides are commonly used for controlling various pests, as they are highly effective and have low toxicity to mammals.
