What causes sweating during running in order to maintain homeostasis? Jenny is running for more than an hour on a pleasant sunny morning. Her body is sweating to maintain homeostasis, which is caused by the action of a/an (blank)

Answers

Increased body temperature did this on plato

Answer:

The correct answer would be "increased body temperature".

The homeostasis refers to the ability of the body to maintain a stable internal environment irrespective of the change in the external environment.

For example, running causes an increase in body temperature as heat or energy, carbon dioxide, and water are produced by cellular respiration. This increase in body temperature activates the sweating of the body.

The sweating with the help of evaporation reduces the elevated body temperature to the normal range.

Thus, homeostasis of body temperature is maintained.

How might a substrate of the citric acid cycle block respiration when it is present in great excess

Answers

The substrate of the citric acid cycle which can block respiration when it is present in excess is MALONATE. Malonate inhibits respiration by competing with succinate dehydrogenase for its acitve site. Malonate binds to the active site without reacting, thus competing with succinate. This disrupts the cellular respiration in the cell.

Mice eat corn. Hawks eat mice. Which term describes hawks in this food chain?

Answers

Answer:

The hawk is a secondary consumer.

Explanation:

The primary producers or the producers are the plants, which can synthesize their own food with the help of sunlight. The consumers are the organism, which depend on other organism for their food requirement they cannot synthesize their own food. The primary consumers are the organism who feed on plant products. The secondary consumers are the organisms who feed on primary consumers. the tertiary consumers are the organism who feed on secondary consumers.

In this case, the mice is primary consumer and the hawk is secondary consumer, as the mice feed on plant product and hawk feed on mice.

Structures that have different functions in different species but develop from the same embryonic tissues are called _______________ structures.

Answers

structures that have diverse develop shapes yet create from the same embryonic tissues are called homologous structures. 

Structures that have diverse develop shapes yet create from the same embryonic tissues are called homologous structures.

What is Homologous structure?

Physical characteristics found in species with a shared origin are known as homologous structures, although these characteristics have entirely different biological purposes.

Divergent evolution leads to homologies. Divergent evolution is the process through which living things that shared an ancestor develop and acquire distinctions, frequently giving rise to new species.

Analogous structures, on the other hand, are comparable physical characteristics in creatures that do not have a common ancestor. Instead, because they serve the same purpose, these structures are connected to one another.

Therefore, Structures that have diverse develop shapes yet create from the same embryonic tissues are called homologous structures.

​Approximately what percentage of the body's energy needs at rest is supplied by fat

Answers

Final answer:

Around 60% to 70% of the body's energy at rest comes from fat. Our metabolism is designed to extract energy from a mix of macronutrients and at rest, the body shifts towards using more energy from fat.

Explanation:

Approximately 60% to 70% of the body's energy needs at rest are supplied by fat. Our bodies are designed to extract energy from a mix of macronutrients including fats, proteins, and carbohydrates. When we are at rest, the metabolism shifts towards using a higher proportion of energy from fat. This shift occurs because fat, although it takes more oxygen to metabolize than carbohydrates, provides a more dense supply of energy. However, the exact percentage can vary based on several factors like diet, physical activity level, and genetics.

The most important and most effective way to control pests in a food establishment is to _______.

Answers

The most important and most effective way to control pests in a food establishment is to implement Integrated Pest Management (IPM). This is an ongoing cycle of inspecting, identifying, analyzing, and treating pests in the establishment.

FURTHER EXPLANATION

There are several steps in implementing the IPM.

1. The first step is to look at the entire establishment and identify areas where pests come through.

2. Once the areas where pests may enter and exit the establishment are identified, an action plan to ensure that pests are unable to pass through are put in place such as covering holes or entry points. Keeping the areas clean and sanitized and observing proper waste disposal are also key practices to help prevent infestation.

3. The kind of pests should also be identified and monitored to be able make an appropriate treatment plan based on their behavior. The correct selection of pest control treatment is necessary to ensure that the treatment is specific to the kind of pests that are found on the site. Also, an analysis of why these pests are found on site must be conducted so that further preventive measures may be put in place.

4. When planning and implementing pest control measures start with non-chemical methods first like baiting and trapping pests. Only when these methods fail should chemical control methods be used and only with doses specifically needed for the identified and targeted pests.

5. Proper documentation of the pest control cycle must be prepared for a smooth implementation of the continuous integrated pest management.

The most effective and most important way to control pests in a food establishment is to implement an integrated pest management program.

Further Explanation:

Humans, pests, and rodents prefer to live in a warm environment in cold or wintery days. That’s why pests find their way inside the building and home if they smell any food. Pests like cockroaches, flies, and rodents may cause harmful disease and people get sick frequently. To prevent food from getting contaminated by pests, the manufactures should apply for an integrated pest management program. It mainly consists of different precautionary phrases that are used to prevent pests out of the facilities and to eradicate the pest that is present in the food. A food safety regulator checks and ensures that the food is fit to be consumed. The pathogens that are present in the food can affect the person. This can result in the transmission of the pathogen.

Answers

A team sport has beyond one player on a side or team. Examples are baseball, football, soccer, hockey and basketball are all team sports. An individual sport has only one opponent playing against each other. Wrestling is one example of an individual sport. Golf is an example of individual sport that can have many rivals in the same game and it can have a group of golfers form a team but each player is an individual player. Tennis is also an individual sport when played as "singles" and a team sport when played as "doubles" but can also have teams put together with singles and doubles.Sports in which only one player per team participates at a time, with individual scores counting toward the team score.

Individual team sports involve teams of members with complementary skills working towards shared goals, where they act collaboratively and share rewards

The correct definition for individual team sports is centered around activities where teams are composed of individual members who are committed to a common purpose and goals and utilize their complementary skills to work cohesively towards a collective objective. Unlike in regular groups, where members may be focused on their own areas, a team acts collaboratively, sharing both the tasks and the rewards. Members are dedicated to the mutual vision and are often ready to sacrifice their individual interests for the good of the team. Examples of individual team sports include soccer and basketball, wherein each player contributes actively by cooperating with fellow teammates, such as by passing the ball to allow another to score, thus achieving success or facing defeat together.

Teams are also characterized as being smaller, task-oriented groups, where members are deeply loyal and strive hard in a unified direction. Success in team sports involves clear and inspiring goals, a results-driven structure, competent members, a collaborative climate, high-performance standards, as well as external support, recognition, and accountable leadership.

Inhalation and exhalation move air into and out of the lungs. what happens when you inhale and exhale? drag the labels to the correct locations on the flowchart to identify the steps of inhalation and exhalation.

Answers

When you inhale or breathe in air, your diaphragm will contract or tighten and it will move downward. This will result to an increase in space in your chest cavity where your lungs will expand. The intercostal muscles located between your ribs will also help in the enlargement of the chest cavity. When your lungs expand, air will flow through your nose or mouth. The air will travel through your wind pipe and into your lungs. It will pass through your bronchial tubes and it will eventually reach and enters the alveoli or the air sacs. 

When you exhale or breathe out on the other hand, your diaphragm will relax and it will move upward into your chest cavity. The intercostal muscles will likewise relax resulting to the reduction of space in the chest cavity. When the space in the chest cavity gets smaller, air that is carrying carbon dioxide will be forced out of your lungs and windpipe and it will eventually go out of your nose or mouth.

Imagine that a probe sent to mars brings back a sample that contains a very primitive life-form, which appears similar to bacteria. scientists are able to revive it and begin to grow it in culture. much to their amazement, they discover that the organism has dna and that the dna encodes proteins. however, the dna of these martian microbes contains only two nucleotides. if the martian microbe uses triplet codons, what is the maximum number of different amino acids that it can have in its proteins

Answers

The formula for the maximum number of different amino acids can be calculated using the equation:

Maximum number of different amino acids = [(Number of nucleotides) ^ (Number of codons)] - 1

Where it is given that:

Number of nucleotides = 2

Number of codons = triplet = 3

The -1 in the equation implies that at least one of the codons must be a stop.

 

Therefore substituting to the equation:

Maximum number of different amino acids = (2 ^ 3) – 1

Maximum number of different amino acids = 8 – 1

Maximum number of different amino acids = 7                        (ANSWER)

What do you call the red pigment found in vertebrates that functions in oxygen transport?

Answers

There are actually two red pigments found in certain vertebrates that function in oxygen transport (or storage). Hemoglobin is present in the blood of most vertebrates and binds oxygen molecules, in order to transport them to body tissues in need of oxygen for energy (ATP) production.
Myoglobin, mainly in mammals, is a protein (enzyme) found in red (skeletal) muscle cells, that aids in binding oxygen when it's plentiful being delivered via blood. The purpose is that in high stress, low oxygen situations such as strenuous exercise, the myoglobin releases its bound oxygen to provide it to the starving overworked muscle cells.
**Fun fact: it's the hemoglobin that gives the bright red color of blood when it's bound to oxygen, and the myoglobin of mammal flesh gives it the typical pinkish-red hue that is seen in mammalian meat (veal, steak, ham, venison, bison, etc.). Other non-mammalian animals (fish, birds, frogs, snake, alligator, etc.) tend to have lighter-colored skeletal muscle meat due to the lack of myoglobin, amongst other factors.

What lung values changed (from those of the normal patient) in the spirogram when the patient with emphysema was selected?

Answers

When the patient with emphysema was selected lung values changed (from those of the normal patient) in the spirogram are:

ERV, IRV, RV, FVC, FEV1, FEV1 %

The reason behind the changes of these values are due to the loss or inability of electric recoil. A spirogram (graph like structure obtained by the respiratory movements) is measured by spirometer.

The lung values that changed include the following: ERV < IRV < RV < FVC < FEV1%. Spirogram is used to measure pulmonary function test. It is a test that tests the efficiency of the lungs to exchange carbon dioxide and oxygen gases. The vital capacity of the lung is equal to TV +IRV + ERV and the total capacity is equal to the summation of TV, IRV, ERV and RV.

Which of the following correctly summarizes the development of the fetus during the second trimester?

Answers

During the second trimester, the fetus grows significantly, reaching about 12 inches in length, and begins to move, which the mother can feel. The placenta takes over nutrition, waste management, and hormone production from the corpus luteum, supporting the continued development of all fetal organs until birth.

During the second trimester of pregnancy, several significant developments occur in fetal growth and development. The fetus grows to about 30 cm (12 inches), and the expecting mother often feels the fetus's first movements. This period is marked by the continuous growth of all organs and structures.

Importantly, the placenta becomes the primary site for nutrition and waste management for the fetus, replacing the corpus luteum. The placenta also takes over the production of vital hormones such as estrogen and progesterone. These changes enable the fetus to progress towards further maturation necessary for eventual birth, and the placenta continues to function until delivery.

The correct option is D Specialization, function, and growth.  The second trimester focuses on the development and refinement of body functions.

The second trimester (months 4-6) is a period of rapid specialization for the fetus. Organs and systems that were formed in the first trimester begin to develop specific functions. Many body functions like swallowing, kicking, and hearing start to develop during this time. This signifies the beginning of function. The fetus also experiences significant growth in size and weight during the second trimester.

The other options are less suitable because

A Body functions, reflex development, and skin details: While these are all aspects of fetal development in the second trimester, they are specific examples rather than a comprehensive summary.

B Cell division and tissue specialization: This is a more general description that applies to earlier stages of development as well.

C Gastrulation, neurulation, and rhythmic breathing: These terms refer to processes that occur much earlier in embryonic development, during the first trimester.

If the concentration of blood is 0.5 M, and red blood cells that are bathed in blood neither shrink nor swell and burst, the concentration of cytoplasm of RBCs is 0.5m. An isotonic solution relates to two solutions that have the same water concentration on both sides of a membrane. So, cells in isotonic solution have the same water concentration as the isotonic solution and thus they will neither shrink nor swell and burst. If the concentration of blood is 0.5 M, the concentration of RBC cytoplasm must be the same which is 0.5 M.

- Each word represents an amino acid which will be  built into a protein later
2)Transfer RNA of tRNA
 - The key to deciphering the mRNA
 - The correct tRNA will adhere to the mRNA in a ribosome with an amino acid in tow which will connect to form a polypeptide chain.
3) Ribosomal RNA or rRNA
 -The rRNA kind of facilitates protein synthesis 
 - It is what forms the protein from a polypeptide chain.
 - Also joins the ribosome together ( Ribosomes are made of 2 subunits)
The process is kind of a visual process. For me, I had to kind see it to actually understand. It is a confusing process to understand from just words.
