processed, shipped out by golgi appratus
Proteins obtained from the ER are further processed and sorted in the Golgi apparatus, or Golgi complex, where they are eventually transported to lysosomes, the plasma membrane, or secretion. As was already mentioned, the Golgi apparatus also produces sphingomyelin and glycolipids. The complex polysaccharides that make up the cell wall are also created in plant cells at the Golgi apparatus. The extensive range of cellular components that go down the secretory pathway are thus processed by the Golgi apparatus.

In the frog embryo, convergent extension elongates the notochord. Explain how the words convergent and extension apply to this process.
Convergence and extension coexist in the frog embryo. In the frog's embryo, united expansion prolongs the notochord.
The notochord's cells converge as a result of moving inward, or toward the center of the embryo. The notochord then extends or elongates due to the cells' subsequent reorganization.
Organogenesis is the process by which the embryo's germ layers create primary organs. In some animals, the germ layer cells have specific functions, and as a result, their future is predestined. However, it is not always the case with all creatures.
The cells of the frog embryo display convergent extension, a type of morphogenic movement or rearrangement. The cells reorient themselves toward the midline and converge due to this type of morphogenic migration.
The notochord extends due to the cells' subsequent self-reorganization by cell lengthening and narrowing.

The production of carbon dioxide during respiration in aerobic tissues lowers the ph in erythrocytes, which in turn ________ the affinity of oxygen binding to hemoglobin.
The production of carbon dioxide during respiration in aerobic tissues lowers the ph in erythrocytes, which in turn decreases the affinity of oxygen binding to hemoglobin.
During internal respiration, carbon dioxide in erythrocytes combines with water to form carbonic acid, which then associates with hydrogen ions and bicarbonate ions. Bicarbonate ions get diffused out of erythrocytes and control the blood ph. Hemoglobin in the RBCs binds with hydrogen ions and reduces the affinity for oxygen. Oxygen then gets diffused out of the RBCs and enters the tissues. The interaction between hemoglobin and hydrogen ions and then its affinity for oxygen is called the Bohr effect.
Internal respiration results in the production of carbon dioxide in aerobic tissues that lowers the oh in erythrocytes through bicarbonate ions. This, in turn, decreases the affinity of oxygen binding to hemoglobin and releases it into the aerobic tissues.

An ecologist studying desert plants performed the following experiment. She staked out two identical plots, containing sagebrush plants and small annual wildflowers. She found the same five wildflower species in roughly equal numbers on both plots. She then enclosed one plot with a fence to keep out kangaroo rats, the most common grain-eaters of the area. After two years, four of the wildflower species were no longer present in the fenced plot, but one species had become much more abundant. The control plot had not changed in species diversity. Using the principles of community ecology, propose a hypothesis to explain her results. What additional evidence would support your hypothesis?
The additional evidence that would support your hypothesis is the place where both living and nonliving things present and interact with each other.
How to illustrate the information?This illustration demonstrates how plant predatory behavior affects the choice of species. The choice of plants in the enclosed area is not influenced by animal predation.
Only other plants will fight for resources in this situation, and one plant had a selection advantage over the other three plant species. The ratio of the four species is the same in the plot that is subject to animal exploitation.
This is probably a result of animals' greater preference for the dominant plant species in the enclosed plot and/or the other three species' anti-animal predation strategies.

The papillary layer of the dermis is most closely associated with which layer of the epidermis?.
Answer:
The papillary layer of the dermis is most closely associated with Stratum Basale layer of the epidermis.
Explanation:
Fibers like collagen and elastin that make up the papillary layer create a loose mesh because this layer is formed of connective tissue of the areolar that is loose. Dermal papillae, which resemble fingers, are formed when this surface of the dermis extends further to stratum basale of something like the epidermis. Columnar basal cells, which are continually dividing and also being forced forward towards the surface, may be found in this layer. Additionally, melanocytes that create melanin (the pigment that gives colour to skin) reside inside the stratum basale.
The various layers of the epidermis regularly regenerate due to epidermal stem cells. . Our hair follicles are constantly renewed because of hair follicle stem cells.

The rate of change faster or slower in that -
Between 1:00 and 6:00 a.m., the rate of change was (37.3 - 9.9)/5 = 5.5 pg/mL/hr. In the short protocol participants, the rate of change occurred more quickly in the first 30 minutes after awakening than it did between 1:00 and 6:00 am.
The morning (6 to 8 am) is when ACTH levels are at their highest, and the evening (late) is when they are at their lowest (6 pm to 11 pm). If they suspect abnormal levels, a doctor may check the ACTH levels in the morning or evening. ACTH and cortisol levels are usually assessed together.The timing of ACTH secretion may be influenced by a person's expectation of waking up at a particular time. 15 healthy participants in their mid-20s had their mean levels of ACTH measured over the course of three nights to evaluate the influence of anticipation.Both the anticipated and actual wake-up times for the experiment in the short protocol are 6 am.

Which technique is dependent upon the release of oxygen from hemoglobin molecules?
fMRI technique is dependent upon the release of oxygen from hemoglobin molecules
fMRI is a powerful tool for studying brain activity, but it is dependent on the release of oxygen from hemoglobin molecules. This means that any condition that affects oxygen release can potentially impact the results of an fMRI scan.
One condition that can affect oxygen release is anemia. Anemia is a condition in which the blood is unable to carry enough oxygen to meet the body's needs. This can lead to a decrease in the amount of oxygen that is released from hemoglobin molecules, and this can in turn lead to less activity being detected by fMRI.
