Unlike semicircular canals , the otolith organs are quite sensitive to shear forces, which are forces parallel to the macular plane.

The otolith organs, specifically the utricle and saccule, are structures in the inner ear responsible for detecting linear acceleration and changes in head position relative to gravity. They contain tiny calcium carbonate crystals called otoliths, which are embedded in a gelatinous matrix. When the head moves or changes position, the otoliths shift and exert pressure on hair cells located within the maculae of the utricle and saccule.

Shear forces are forces that act parallel to a surface or plane. In the context of the otolith organs, shear forces are created when the head undergoes linear acceleration or changes in position. These shear forces cause the otoliths to move or slide within the gelatinous matrix, leading to deflection of the hair cells and the generation of nerve impulses. This allows the brain to perceive changes in head position and linear acceleration.

In contrast, the semicircular canals are more sensitive to rotational or angular movements rather than linear acceleration. They detect changes in head rotation and contribute to the sense of balance and spatial orientation. The otolith organs and semicircular canals together form the vestibular system, which plays a crucial role in maintaining balance and coordinating movements.

The production of antibodies inside the lymphocytes starts at the ribosome (organelle) by joining amino acids together, creating peptide bonds, and forming the primary level structure polypeptide. The polypeptide bends and folds tertiary in the Golgi apparatus (organelle), to form the next level of structure. For instance, the secondary level of structure is formed by hydrogen bonds to create alpha helix or beta-pleated formations.

In order for an antibody to be released into the blood, a fully formed antibody will move from rough endoplasmic reticulum (organelle) to another organelle named Golgi apparatus to sort and be processed for shipment out of the cell. Antibodies transport from organelle to organelle and to the plasma membrane in a vesicle, which is made out of fatty acids-phospholipids.

The expected proportions (percentages) for the other 3 bases would be: - Adenine (A): 31.5%, - Thymine (T): 31.5%, - Guanine (G): 16.5%.

If an organism's genome contains 36ytosine, the expected proportions (percentages) for the other 3 bases are:

- Adenine (A): The percentage of adenine (A) is expected to be equal to the percentage of thymine (T) as they pair together in DNA. So, if we assume that the genome has an equal proportion of A and T, then the percentage of A would be 31.5% [(100-36)/2].
- Thymine (T): The percentage of thymine (T) is also expected to be 31.5% [(100-36)/2].
- Guanine (G): The remaining base is guanine (G). To calculate its percentage, we need to subtract the percentages of A, T, and C from 100. So, if we assume that the genome has an equal proportion of all bases, then the percentage of G would be 16.5% [(100-36-31.5-31.5)].

Therefore, the expected proportions (percentages) for the other 3 bases would be:
- Adenine (A): 31.5%
- Thymine (T): 31.5%
- Guanine (G): 16.5%.

By matching the components involved with protein import into the ER with their cellular locations, we get:  

Signal recognition particle: 1. cytosol

Protein translocator: 3. ER membrane

mRNA: 1. cytosol

SRP receptor: 3. ER membrane

Active site of signal peptidase: 2. ER lumen

Several elements are crucial for protein import into the endoplasmic reticulum (ER). A cytosolic protein called the signal recognition particle (SRP) identifies and attaches to the signal peptide on the developing protein as it leaves the ribosome.

The SRP then directs the ribosome-nascent protein-SRP complex to the ER membrane's SRP receptor. The nascent protein is moved more easily over the ER membrane and into the ER lumen thanks to the protein translocator, which is also a component of the ER membrane. The ER lumen contains the signal peptidase active site, which cleaves off the signal peptide. The nascent protein's mRNA can be found in the cytosol as well.

Plant, it has a rectangluar, box shape and is green.

Explanation:

Answer:

The respiratory system and lungs work very closely with the cardiovascular system for the uptake and elimination of gases and the distribution of energy in the body. Oxygen from the air is absorbed into the bloodstream through the lungs. When it reaches the lungs, the function of the cardiovascular system begins, since that is where the non-oxygenated blood is oxygenated and returns to the heart. When in the cardiovascular system, the blood reaches the capillaries in the tissues, oxygen is released, which the cells use to produce energy. These cells release waste products, such as carbon dioxide and water, which are absorbed and transported by the blood.

Explanation:

O2 and CO2 are constantly circulating and passing from one medium to another, so much so that: O2 passes, along with other gases, from the atmosphere to the airways, entering through the nostrils and driving through the larynx, trachea, source bronchi, terminal bronchioles, respiratory bronchioles, alveolar sacs and alveoli. From here, the O2 diffuses through the respiratory membrane towards the pulmonary capillaries, and from these, in a totally different environment from the previous one (liquid instead of air), it circulates throughout the systemic arterial tree towards the tissues; where upon arrival it will enter the cells, crossing their membranes and exchanging with CO2. CO2, for its part, will follow the exact opposite path of O2, until it exits through the nostrils into the atmosphere. Once the inspired air reaches the alveoli, it is ready to perform hematosis, which is carried out thanks to the pressure gradient, of O2 and CO2, which exists between the alveolus and the pulmonary capillary. In such a way that O2 diffuses, in favor of a gradient, towards the blood and CO2, in the opposite direction, does so towards the alveolus. When O2 passes into the blood, an exchange takes place in the tissues (internal respiration). It dissociates from hemoglobin, diffusing from the intracellular fluid of the erythrocyte into the plasma, and from there it is distributed through the bloodstream to all cells of the body.

Answer: Water, Sunlight, and Soil

Explanation: Water is needed for any life to exist in a ecosystem, sunlight lets plants create their food and thus feed the rest of the food web, and soil is also needed for plants to take root and grow to feed others.

Photosynthesis occurs in two stages, light-dependent reactions and light-independent reactions. Water and sunlight enter light-dependent reaction. Oxygen exits light-dependent reaction. Carbon dioxyde enters Calvin cycle. Glucose exits Calvin cycle. ATP and NADPH exit light-dependent reaction and enter calvin cycle. ADP and NADP+ exit  calvin cycle and enter light-dependent reaction.

Photosynthesis is the process through which plants take sunlight to produce organic products. It is composed of two main stages, light-dependent, and light-independent reactions.

During light-dependent reactions,

During light-independent reactions,

Both processes alternate to help the cell conserve energy and matter.

The hormone that is stimulated by stress is adrenocorticotropic hormone (ACTH). So, option C is accurate.

When the body experiences stress, the hypothalamus, a region in the brain, releases a hormone called corticotropin-releasing hormone (CRH). CRH then stimulates the anterior pituitary gland to produce and release adrenocorticotropic hormone (ACTH). ACTH, in turn, acts on the adrenal glands, specifically the adrenal cortex, to stimulate the release of cortisol, a stress hormone.

Cortisol plays a crucial role in the body's response to stress by increasing blood sugar levels, suppressing the immune system, and aiding in the regulation of various physiological processes. It helps the body prepare and adapt to the stressor.

While other hormones listed in the options, such as thyroid-stimulating hormone (TSH), prolactin, and follicle-stimulating hormone (FSH), have important functions in the body, they are not primarily associated with the stress response. Their release is regulated by different mechanisms and stimuli unrelated to stress.
