5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.

Answers

Answer

The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.

Explanation:

The brain stem, consisting of the pons and medulla, represent the main respiratory center.   According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."

This is an example of a homostastic response controlled by both of the organ systems referenced above.

Scientists are studying the mating habits of a population of butterfly fish on a Caribbean coral reef. They discover that both the largest and smallest males get the most mates and pass on the largest number of genes to the population's offspring. The largest males get a large number of mates because they can guard the females, preventing most of the smaller males from mating. However, the very smallest males also get a large number of mates because they escape the notice of the larger males and are able to mate with the females quickly. Based on these observations, which selective force appears to be acting on male body size in this population?

Answers

Answer:

The correct answer is - Disruptive selection.

Explanation:

Disruptive selection is a mode of natural selection that exhibits that two extreme values of phenotypic traits of the population are favored by this population than the population with their intermediate values. Disruptive selection occurs when there is a fitness advantage of extreme values of phenotypic traits over more intermediate phenotypes.

In this case, the largest males mates more, due to fact that they can guard the females, than smaller males. The smallest fishes also get a high number of mates as are able to mate with the females quickly without coming to the notice of larger males.

What characteristics of the blood cell helps it to pass freely through blood capillaries

Answers

Answer:

The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.

Answer:

The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.

Explanation:

The hemoglobin in red blood cells contains four iron-binding heme groups.

Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.

Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.

The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.

The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.

Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.

CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.

Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

When and where would you expect to find the highest rate of primary productivity

Answers

Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.

Explanation:

I explained on the top-

The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.  

• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.  

• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.  

• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.  

• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.  

• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.  

These environments are mainly critical for the sustenance of global biological productivity.

Name & describe the six essential activities of the digestive tract.

Answers

Answer:

Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.

Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.

Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.

Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.

Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.

HELP! What evidence indicates that many psychological disorders, such as schizophrenia and developmental
disorders, are biologically and not environmentally based?

Answers

Answer:

Schizophrenia and developmental disorders are traced genetically, and the gene will be found in the biological parents of the person with either schizophrenia or developmental disorders.

Explanation:

Although Schizophrenia can be triggered by environmental factors, or the 'nurture' of childhood development, a person who is not predisposed genetically to schizophrenia will not get the psychological disorder. The same is to be said about developmental disorders such as Autism and ADHD, it is hereditary.

For citation of evidence, I recommend talking about prenatal development, and how toxic substances can alter the development of a fetus, which is proven to lead to some developmental disorders, such as Fetal Alcohol Syndrome.

Answer:

Schizophrenia and developmental disorders are genetically connected, and the gene will be found in either the individual's biological parents or the person suffering from schizophrenia or developmental abnormalities.

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.

Your answer: Here are 3 reasons that go against growing wheat this way.

1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.

2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.

3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.

If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)
