To survive, an organism must be able to maintain stable internal conditions in a changing environment. This process is called homeostasis. The Human Homeostasis Gizmo™ allows you to explore how the human body stays at a nearly constant temperature in different conditions. Notice the Air temp. and Body temp. thermometers representing the air temperature and body temperature.
1. What is the initial air temperature?
2. What is the initial body temperature?
3. Next to each factor listed below, write "increase," "decrease," or "same" based on how you expect that factor to affect body temperature.
A. Raising air temperature: __same____Sweating: __decrease___.
B. Lowering air temperature: ___increase___Shivering: __increase___.
C. Adding clothing: __increase_____Exercising: ___increase_____.
Answer:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
Explanation:
The question is incomplete, it is necessary to look for a software related to this homework.
Homeostasis is a property of organisms that consists in their capacity to maintain a stable internal condition by compensating for changes in their environment through the regulated exchange of matter and energy with the exterior. It is a a dynamic equilibrium controlled by a mechanism of feedback that constitute the self-regulating mechanisms. Examples of homeostasis are temperature regulation and the balance between acidity and alkalinity (pH)
The Human Homeostasis Gizmo™ is a software that allows you to explore how the human body stays at a nearly constant temperature in different conditions. To use it, you have to set the air temperature at 0 °C (32 °F) and the body temperature at 37 °C (99 °F), and click Play. After a simulation of 1 hour, then click Pause and gather the information. Then, do the same cprocedure to test the effect of other factors and Click Reset between each trial. To determine the effect of different factors on body temperature, you have to compare the final body temperature to the final body temperature while there is no specific movement or change.
Then:
1. Initial air temperature: 0 °C (32 °F)
2. Initial body temperature: 37 °C (99 °F)
3. The expected effect of different factors on body temperature are:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Adding clothing: Increase
D. Exercising: Increase
This is for a logical reason, anything you do to heat it or generate heat, will increase the temperature. And anything you do to generate cold, will lower the temperature.
The effect of different factors on body temperature according to Gizmo:
A. Raising air temperature: Increase
B. Lowering air temperature: Decrease
C. Click Add to a sweatshirt, hat, pants, and parka. Then, adding clothing:
Maintained
D. Set the Exercise level to 70%, then exercising: Increase
When the temperature increases, it is because you are able to record the results from the software and you see temperature goes from 99 °F to 100 °F. When the temperature decreases. it is because it goes from 99 °F to 97 °F. When it is maintained, there is no change.
Some students looked at pond water with a microscope. They saw prokaryotic and eukaryotic
organisms. The diagram shows one of the many organisms they saw.
Which best explains what type of organism this is? LT
(2 Points)
Answer:
C. Eukaryotic because it has a nucleus
Explanation:
All living organism have been classified into a wide category called DOMAIN, which consists of Eukarya, Prokarya, and Archaea. Living organisms are classified into each of these domains mostly based on whether or not they possess NUCLEUS in their cells.
Domain Eukarya known as Eukaryotes are made up of organisms that possess a membrane-bound NUCLEUS in their cell. According to this question, some students looked at pond water with a microscope and saw both prokaryotic and eukaryotic organisms. The organism displayed in the attached image is EUKARYOTIC simply because it has a NUCLEUS.

Describe how the color of a person's eyes is determined.
Answer:
Variations in a person's chromosomes decide eye colour.
Explanation:
At rest the lens of the eye will be more round when the ciliary muscles are contracted true or false
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.

In a semi-conservative model of DNA replication, which of the following is true?
Answer:
According to the semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. ... Each subsequent round of replication would then produce double helices with greater amounts of new DNA.
The semiconservative model, after one round of replication, every new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA. Each subsequent round of replication would then produce double helices with greater amounts of new DNA.
Why do they call it semi-conservative?This ]method is known as semi-conservative replication because two copies of the original DNA molecule are made, each copy conserving (replicating) the details from one half of the original DNA molecule.
Each copy has one actual strand and one newly-synthesized strand.
Thus, new DNA double helix would be a hybrid that consisted of one strand of old DNA bound to one strand of newly synthesized DNA.

Which statement correctly identifies one advantage and one disadvantage of relying on trains for
transportation?
Your answer:
Trains are inexpensive to build, but require too much open land.
O Trains are convenient and comfortable, but have a limited range.
Trains can damage habitats from pollution, but can be easily rerouted.
Trains can reduce congestion, but typically increase overall fossil fuel use.
Trains can have inconvenient schedules, but produce less pollution than cars do.
Answer:
The correct answer is - Trains can have inconvenient schedules, but produce less pollution than cars do.
Explanation:
Trains are expensive to build and also required land for making routes and stations and platforms for passengers but that can be reimbursed by fare in a longer time period.
Trains also produce pollution but in comparison to cars these are way less contribute to the pollution, However, these are not convenient as they start and reach at a specific time and also sometimes not comfortable like cars.
Four scientists observed an area of land that had been cleared of all trees and bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted?
Answer:
The ecosystem is adversely affected.
Explanation:
The ecosystem is adversely affected due to clearing of all trees and bird population is also adversely affected because these trees are the source of habitat for these birds. When there is large number of birds in an ecosystem so the bird population automatically increases due to the presence of more habitat for the birds so if all the trees are removed so very little population of birds left in that ecosystem and this action leads to great disturbance in the ecosystem.

Use the information gathered in the A Three Point Test Cross animation to answer the question. Genes H and K are linked and are known to be 3.5 m.u. apart on the same chromosome. What is the recombination frequency between H and K
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, crossing over or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/loci located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/loci (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.

Ian is an 18-year-old gymnast training at a private gym with many other male and female gymnasts. he is competing at an advanced level and is likely to make the next Olympic team. Lately, he has found that some of his balance and strength moves on the rings and parallel bars have become more difficult. He has gone through a bit of a growth spurt and gained approximately 5 pounds over the last year. He suspects the weight gain is causing his performance difficulties. He decides to try a weight-loss program that will help him lose weight before his next big competition in 6 weeks. He is not sure how many calories to consume and therefore arbitrarily decides to eat 1,500 calories per day.
1. Which assessments are required to determine whether Ian needs to lose weight?
2. What type of diet and exercise plan would you recommend for Ian?
3. What additional concerns do you have for Ian's health and sport performance?
Answer:
Explanation:
(1.)
Assessments needed to reduce Ian’s body weight:
A weight-loss program should allow the loss of weight should be fat loss, and the increase of weight should be body muscle mass. Weight reduction should be accompanied by an acceptable exercise regimen (both strength and conditioning). A well-balanced diet with sufficient energy (calories), carbohydrates, protein, and fat should be part of every weight-loss regimen. Excessive exercise resulted in weight loss. Using anorexic medications, laxatives, insulin, diet tablets, stimulants, diuretics, dietary products, or any lawful or illicit drugs and/or nicotine should be banned at all levels.
(2)
type of Diet:
Every day, Ian must eat three meals and just a snack. A fiber-rich cereal with skim milk and fresh fruit can be a better way to start the day.
After that, have a bologna sandwich on the whole bread with fruit or a big vegetable-rich salad together with a small turkey sandwich in addition to a cup of skim milk for lunch.
Poultry hen should be served with potatoes (baked), mixed vegetables, and skim milk for dinner. An early workout snack of a small butter muffin or yogurt combined with cereal should also be included.
Exercise Plan:
i) Bodyweight fat recovery can be supported by proper and secure aerobic activity.
ii) The right kind of aerobic exercise is extremely beneficial for weight loss.
3. Gymnastics is a visually appealing discipline that necessitates speed, strength, and coordination. Most high-level gymnasts eat less than the recommended amount of calories and certain nutrients for their age and training load, according to dietary tests. Young gymnasts, in particular, must absorb enough energy and nutrients to satisfy the demands of growth, exercise, performance, and tissue conservation. Poor energy supply, disordered eating habits, and eating disorders are all factors that can damage a gymnast's long and short-term health. Some gymnasts cross the line into extreme, treatable eating disorders by dieting and using infective weight-loss strategies.
In light of these considerations, Ian should pay attention to his health and diet. Ian should limit his consumption of added sugar intake and increase his fiber intake to help him achieve his body fat targets. Gymnasts can consume at least 1.4–1.8 grams of carbohydrates each pound (3–4 g/kg) per day. Increased protein consumption helps to reduce the amount of muscle lost over a weight-loss cycle. Per day, gymnasts can eat 0.8–1.2 g/lb (1.8–2.7 g/kg) of protein.
Ian would be able to shed weight and prevent an eating disorder in this manner.

which is more common grass or humans?
Answer:
Grass
Explanation:
Cause most human food comes from grasses, directly as grain or indirectly as feed for meat and dairy producing animals.
people- estimate that humans have modified >50% of Earth's land surface.
The grass family, Poaceae, is one of the largest plant families, and, to humans, perhaps the most important, as it includes agricultural grains such as wheat, rice, maize (corn), and sugar cane. The Poaceae comprise about 600 genera and perhaps ten thousand species. It is estimated that grasslands cover about 20 percent of the earth's land area.
so the answer is humans
