What happens when two species occupy the exact same niche
A. One will cause a primary disturbance
B. They will both increase in population
C. They will help each other
D. Only one will survive
Answer: D. Only one will survive
Explanation:
An ecological niche can be define as the functional role an organism plays in an ecosystem so as to survive. Like, the mode of nutrition, type of habitat chosen for survival and season chosen for breeding are the examples of ecological niche.
If two species occupy the same ecological niche, the species which is more superior over the other will receive all the resources. The species which is inferior will decline and extinct according to the competitive exclusion principle. Hence, only one species will survive.
Which idea did Linnaeus contribute to the theory of evolution?
All living things inherit acquired characteristics.
Humans tend to reproduce at a faster rate than the food supply.
The goal of organisms is to adapt and to strive for perfection.
Organisms can be classified based on similar traits.
Organisms can be classified based on similar traits.
Explanation;Carolus Linnaeus is considered the Father of Taxonomy because he developed a way to name and organize species that we still use today. Taxonomy is the science that focuses on naming, identifying and classifying or grouping organisms.One of his contributions was the development of a hierarchical system of classification of nature.Linnaeus contributed the idea that D. organisms can be classified based on similar traits.
Linnaeus, a Swedish botanist and taxonomist, made significant contributions to the theory of evolution by introducing the hierarchical system of classification known as taxonomy. He developed a system for naming and organizing living organisms based on their shared characteristics, which laid the foundation for modern biological classification. Linnaeus classified organisms into a hierarchical structure of kingdoms, classes, orders, genera, and species, based on their morphological similarities.
This classification system was instrumental in organizing the diversity of life on Earth and provided a framework for understanding evolutionary relationships among species. By grouping organisms with similar traits into categories, Linnaeus implicitly acknowledged the concept of common ancestry and the idea that organisms share a degree of relatedness due to their evolutionary history. His work paved the way for future researchers, such as Charles Darwin, to build upon the idea of common descent and develop the theory of evolution by natural selection.
Therefore, Linnaeus' contribution to the theory of evolution was his establishment of a systematic method for classifying organisms based on their shared traits, which provided evidence for the interconnectedness of life and the concept of descent with modification.
The correct option is D) Organisms can be classified based on similar traits.
What does the plasma membrane of a phagocyte attach to on a microorganism? what does the plasma membrane of a phagocyte attach to on a microorganism? pseudopods glycoproteins lysosomes phagosomes?
The plasma membrane of a phagocyte attach to on a microorganism is called the glycoproteins. The glycoproteins’ functions are to identify, adhere to and communicate with the cell, among other functions. This only happens when these glycoproteins are already located in the cell membrane. Sugar molecules are attached to these glycoproteins which are actually proteins. Gathered into short chains which are called the oligosaccharides, these sugar molecules are all found in this area. The glycoproteins are used by the cells which are embedded in the plasma membrane to get the oligosaccharides on the outside of the cell. These glycoproteins normally are attached to the polypeptide side-chains.

Explain why animal cells cannot capture energy from sunlight and use it to make food
Plants and other organisms convert sunlight, water, and carbon dioxide into food (sugar). Photosynthesis requires chlorophyll. Animal cells lack chlorophyll and cannot photosynthesis.
Why can't animal cells make their own food?The primary transformation of the light energy from the sun into the form of chemical energy that may be utilized by living things takes place in organelles called chloroplasts.
In contrast to plant cells, animal cells do not have chloroplasts, which are organelles that are able to harness natural energy sources such as solar radiation and convert simple chemicals into more complex ones. Chloroplasts have the ability to take in sunlight and make use of it, together with water and carbon dioxide gas, in the process of producing food.
Therefore, animal cells cannot synthesize food from sunlight due to lack of chloroplast.

If renewable energy resources can be replaced, why do we need to conserve them?
Mismanagement will deplete resources. Renewable resources remain longer if used wisely and properly. Conserving resources reduces waste.
What is renewable energy resources?Energy that comes from a source that does not deplete over time is referred to as renewable energy. They are natural, they can regenerate themselves, and their carbon footprint is typically very small or nonexistent. Wind power, solar power, bioenergy (organic matter burned as a fuel), and hydroelectric power, including tidal power, are all examples of renewable energy sources. Tidal power is also a form of hydroelectric power.
If the available resources are managed irresponsibly, then most of them will be depleted. However, the lifespan of renewable resources is significantly extended by careful and effective application of such resources. People are able to reduce their waste and better manage natural resources if they practice conservation.

Which of these beakers contains a solution? Explain the answer. In the beaker that has been determined to contain a solution, identify the solute and the solvent.
Answer:
Solution may be defined as the mixture of two or more different substances. The two main different components of the solution are the solute and solvent in the mixture.
Solute may be defined as the substance that dissolved in the solvent. So, the salt and oil is the solute as they are dissolved in the solution. Solvent may be defined as the substance in which the solute is dissolved. So, water is a solvent in which the oil and salt is dissolved to make a solution.

A client rescued from a burning building has partial- and full-thickness burns over 40% of the body. which initial physiologic change will the nurse expect?
Why does an action potential only move in one direction?
Action potentials move in one direction due to the refractory period, which inactivates sodium channels in the previous axon segment, preventing backward propagation. This ensures the signal moves from the cell body to the presynaptic terminal continuously. The all-or-nothing nature of action potentials also supports this unidirectional movement.
Action potentials only move in one direction—from the cell body to the presynaptic terminal—due to the refractory period, which prevents them from moving backward down the axon. This period occurs because after an action potential passes through a segment of the axon, the voltage-gated sodium channels in that segment become inactivated and cannot reopen immediately. As the action potential moves from one Node of Ranvier to the next, the downstream segments are depolarized while the upstream segments remain in a refractory state, ensuring that the action potential can only move forward toward axon segments with closed sodium channels ready for rising phase depolarization.This mechanism is supported by the all-or-nothing nature of action potentials, where each depolarization opens the next set of sodium channels, propagating the signal unidirectionally and with full strength down the axon.Treatment of irritable bowel syndrome usually includes making dietary changes and _____.
What types of cells do not undergo mitosis
Cells that do not undergo mitosis include mature differentiated cells like neurons and cardiac muscle cells, and reproductive cells or gametes that reproduce via meiosis.
Explanation:The type of cells that do not undergo mitosis include most mature differentiated cells such as neurons and cardiac muscle cells. These cells are considered to be in the permanent phase or G0 phase, where they are metabolically active but do not divide.
Also, cells that reproduce through a different process known as meiosis do not undergo mitosis. These cells include the reproductive cells or gametes (sperm and egg cells) in both animals and plants.
While most cells in the body do undergo mitosis for growth and repair, these specified cells do not.
In biology, not all cells undergo mitosis. Cells that do not undergo mitosis are called permanent or non-dividing cells. Examples of non-dividing cells include nerve cells, muscle cells, and red blood cells. These cells have specific functions and do not typically reproduce or divide.

Academic learning occurs most effectively in a cycle of four steps:
After a subtotal gastrectomy, a client has a nasogastric (ng) tube to continuous low suction. three hours after the surgery, the client complains of nausea and abdominal pain. the client's abdomen appears distended. the nurse should first:
The appropriate action that nurse should do first is to take note of the signs that can be a suspect of nasogastric tube blockage and that it is needed to instill about 30 ml of air in which will reestablish the patency. Next step is to also take note that the opioids used can increase nausea and abdominal detention and that it decreases peristalsis. The nurse should tell the client and notify them that there will be no stool for several days and that because of the surgery in which is also expected that there are no bowel sounds to be produced.
Final answer:
When a client post subtotal gastrectomy with an NG tube complains of nausea and abdominal distension, the nurse should first check the patency of the NG tube to ensure it's not blocked or kinked. Clearing the obstruction or adjusting the tube may relieve symptoms. If unsuccessful, the medical team should be notified.
Explanation:
The first step a nurse should take when a client complains of nausea and abdominal pain, with an appearance of a distended abdomen post subtotal gastrectomy with an NG tube set to continuous low suction, is to check the patency of the NG tube. A blocked or kinked NG tube can prevent the proper evacuation of stomach contents, leading to increased pressure in the stomach and intestines, which may cause the symptoms described. Ensuring the NG tube is functioning correctly can relieve the client's discomfort and prevent further complications.
If, upon inspection, the NG tube is confirmed to be blocked or malfunctioning, the nurse should attempt to clear the obstruction or readjust the positioning of the tube. If these efforts are unsuccessful, it's essential to notify the surgical or medical team immediately for further assessment and intervention. Early detection and management of postoperative complications such as tube obstruction can significantly improve patient outcomes.

__________ fats or lipids form animal body fat that is used for stored energy and insulation.
a.Hydrogenated
b.Reconstituted
c.Saturated
d.Unsaturated
Answer:
C
Explanation:
Saturated fats are usually solid at room temperature. This is why the fats in the body of animals are solid (the white mass under the skin and surrounding organs like the liver and heart). Saturated fats have such properties because their carbon chains have very few to no double bonds. Therefore their chains have no kinks that interrupt hydrogen bonding between adjacent chains. This helps the chains to stick tightly together increasing the boiling and melting point of these fats/lipids.
Plants, on the other hand, usually have unsaturated fats/lipids.
The answer is C.) Saturated

A bursting forth of blood from the stomach is known as
A bursting forth of blood from the stomach is commonly related to a severe peptic ulcer that has caused gastrointestinal bleeding, often leading to hematemesis, which is the vomiting of blood.
A bursting forth of blood from the stomach is often related to a condition known as a peptic ulcer. This ulcer is a sore in the lining of the stomach, which can sometimes become severe enough to expose blood vessels and lead to bleeding, also known as gastrointestinal bleeding. Factors contributing to ulcer formation include the destruction of the gastric epithelium, leading to acid reaching the stomach wall. Furthermore, ulcers can be formed due to a variety of other reasons such as Helicobacter pylori infection, chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs), or stress.
Emesis, or vomiting, can occur as a body's response to this condition, expelling blood along with stomach contents. Alarmingly, a severe ulcer can expose the wall of stomach vessels causing bleeding that can pose a threat to one's health. This loss of blood can result in what is known as a hematemesis, which is vomiting of blood that may appear as bright red or have a coffee-ground appearance due to partial digestion by acidic digestive juices.
Acute symptoms leading to these severe complications can be a burning sensation or pain in the upper abdomen, often worsening at night and improving with eating, as well as gastroesophageal reflux disease (GERD) which involves heartburn.
