It can be inferred that a person who has lost sight in one eye, will come to predominantly use which of the following type of information to perceive depth?I. Binocular vision II. The clarity of objects III. Retinal disparities
The answer is II
The clarity of objects. The clarity of objects will allow the individual to perceive depth.
The clarity is the object for the eyes of a personal
What is the answer to this!?

Which best describes the relationship between two species and a niche?If two species have the same niche, one species will always become extinct. Two species are able to occupy the same niche in the same habitat. Two species cannot occupy the same niche in the same habitat. If two species have the same niche, one species will always move.
If two species have the same niche, one species will always move.
In biology, ecological NICHE refers to how the species of an organism performs in its ecosystem i.e. its role. Niche includes the reproduction, feeding pattern, prey, etc. However, if there are two species occupying the same niche, one species will always move.
One of the species, usually the weak one, will always move because occupying the same niche by two species will inevitably lead to competition, which causes one of the species to go elsewhere when these resources are limited.
If two species have the same niche, one species will always become extinct. This is known as the competitive exclusion principle. Hence option A is correct.
It states that two species cannot occupy the same niche in the same habitat and stably coexist. This is because they will compete for the same resources, and one species will eventually outcompete the other.
The only way for two species to occupy the same niche in the same habitat is if they have some kind of mechanism to prevent competition. For example, two species of birds may have different beak shapes that allow them to eat different types of food. This is known as resource partitioning.
If two species have the same niche and no mechanism to prevent competition, then one species will eventually become extinct. This is because the species that are better adapted to the environment will outcompete the other species and eventually drive it to extinction.
In an experiment investigating the mechanism of protein secretion, researcherstracked the movement of radioactively labeled polypeptides in pancreatic cells. At various times after the labeling, samples of the cells were observed using an electron microscope to determine the location of the radioactively labeled polypeptides. Figure 1 summarizes the results at 5 minutes, 15 minutes, and 30 minutes. The dark dots in the figure represent the radioactively labeled polypeptides. Nucleus Golgi Secretory Vesicles Time 5 min ER 15 min 30 min Figure 1. Radioactively labeled polypeptides Using the experimental results, describe the pathway that secretory proteins take from their synthesis to their release from the cell. (3 Points)
First, the polypeptides are synthesised and folded in the endoplasmic reticulum, which is a series of folded membranes.
Then, the polypeptide is packaged into vesicles and moved into the Golgi apparatus, which are stacks of flattened sacs. At the Golgi apparatus, the polypeptide is modified, forming the final structure of the protein. The proteins are then packaged in to vesicles to be transported to their final destination outside of the cell.
The proteins are delivered outside the cell in vesicles via a process called exocytosis. The vesicles reach the membrane, fuse with the membrane, and are then delivered outside the cell.
One of the major useful functions or roles of bacteria in the ecosystem includes: Group of answer choices production of sugar production of hydrogen peroxide metabolization of sugar decomposition of organic matter
The major role of bacteria in the ecosystem is the decomposition of organic matters.
The breakdown of these organisms and the release of the nutrients back to the environment is what called decomposition. These bacteria found in our ecosystem convert gaseous substances like nitrogen into nitrates or nitrites as a part of their metabolism and the product resulting from this process will be released to the environment.
Answer: Decomposition of organic matter
Decomposition is a biological process that involve the breakdown of complex organic matter into smaller molecules to release minerals forms of nutrients and carbon dioxide. Bacteria help in decomposition by feeding on them and release nutrients. There are two forms of decomposition, the aerobic I.e it occur in the presence of oxygen by the activities of aerobic bacteria or anaerobic decomposition which occur in the absence of oxygen by the activities of anaerobic bacteria.
