Answer:
systems
Explanation: Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems. All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
Organ systems are made up of multiple organs that work together to maintain homeostasis in an animal or multicellular animals. In animals, organ systems are seen, which coordinate to form an organism.
What is an organ system?Multicellular animals are made up of multiple cells, and these cells work together to make a tissue. All the cells in a tissue have a single function, such as epithelial tissue or nervous tissue; these tissues form the organs. An example is the stomach, which is made up of different types of tissue such as longitudinal smooth muscle, circular smooth muscle, etc.
These organs collaborate to form organ systems like the digestive system, which includes the stomach, small intestine, pancreas, liver. Organs such as the stomach digest food in the organ system, and the small intestine aids in the process by allowing it to absorb into the blood along with digestion. Organ systems are interdependent, such as the digestive system, which is dependent on the nervous system, the circulatory system, and so on.
hence Organ systems are made up of multiple organs that work together to maintain homeostasis.

6.what type of survivorship curve would you expect for a plant species in which only a few seeds are produced and most of these survive to produce adult plants?
A plant species that produces few seeds with high survival rates would exhibit a Type I survivorship curve.
A Type I survivorship curve is typically observed in species with high survival rates during early and middle life stages, followed by a sharp decline in survivorship as individuals reach old age. This pattern is commonly associated with species that exhibit parental care and invest significant resources in the survival and well-being of their offspring.
In the case of the plant species you described, where only a few seeds are produced but most of them survive to become adult plants, it suggests that the species has mechanisms in place to ensure the survival and growth of its offspring. This could include factors such as protective seed coverings, nutrient-rich seed reserves, or specific adaptations that enhance seed germination and early growth.
The high survival rate of the seeds leading to the development of adult plants indicates successful reproduction and efficient utilization of resources. This suggests that the species has evolved strategies to maximize the survival and growth of its offspring, resulting in a Type I survivorship curve.
Overall, a Type I survivorship curve in this plant species reflects a life history strategy that prioritizes the survival and successful reproduction of a relatively small number of offspring.

In the vestibule of the inner ear, what are the utricle and saccule function?
The utricle and saccule are two structures in the vestibule of the inner ear, which is responsible for detecting changes in linear acceleration and head position.
Both the utricle and the saccule contain specialised sensory cells called hair cells and are filled with a fluid called endolymph. These hair cells are in charge of detecting the movement of otoliths, which are tiny calcium carbonate crystals located on top of the hair cells.
The utricle and saccule work together to keep the body balanced and oriented by sending information to the brain about the position and movement of the head.

Explain the differences in the answers between the two tables. Why
are there differences? Which is more accurate?
The two tables have different results because the first table is estimating the speeds based on the speedometer, while the second table is using conversion factors to convert the speeds from miles per hour to kilometers per hour.
What is speedometer?A speedometer is a device used to measure the instantaneous speed of a vehicle. It is typically mounted on the dashboard of a car or truck, and displays the speed of the vehicle in either kilometers per hour (KPH) or miles per hour (MPH). The speedometer uses a cable connected to the transmission of the vehicle, which rotates at a speed proportional to the speed of the vehicle. The speedometer then converts this rotational speed into a speed reading. Modern speedometers also feature a digital display which can show a variety of other information, such as fuel level, engine temperature, and trip odometer.
The second table is more accurate since it is using a conversion calculation instead of an estimated speed.

which glands secretes hormones that enable the body to respond to stress?
The adrenal glands secrete hormones that enable the body to respond to stress. Specifically, they release cortisol and adrenaline which trigger the body's fight or flight response.
The endocrine glands known as the adrenal glands (sometimes referred to as suprarenal glands) generate a number of hormones, including adrenaline and the steroids cortisol and aldosterone. Over the kidneys, they are located. Each gland has an inner medulla and an outer cortex that makes steroid hormones. The zona glomerulosa, zona fasciculata, and zona reticularis are the three primary zones that make up the adrenal cortex. Mineralocorticoids, glucocorticoids, and androgens are the three primary classes of steroid hormones that are produced by the adrenal cortex. Blood pressure and electrolyte balance are regulated by mineralocorticoids made in the zona glomerulosa, such as aldosterone.

Goats were introduced to a number of the Galapagos Islands several centuries ago to provide food for people who were colonizing the area. Because there were previously no large grazing mammals on the islands, the domestic goats had a large negative effect on native plants and animals. Since their introduction they have drastically altered and reduced the amount of vegetation available and even driven some native species close to extinction. Question 14 options:
The goats have used up most of their food
The goat population has stopped reproducing
Competition among the goats inhibits further population growth
Abiotic environmental factors inhibit further population growth
Other species use up most of the resources
On the island of Northern Isabela, the goat population grew rapidly for about 30 years, but began to level off at a population size of approximately 100,000 individuals (see graph below). Which ONE of the following statements provides a good explanation as to why the curve below levels off?
The curve below levels off because competition among the goats inhibits further population growth.
As the goat population increased, the available resources such as vegetation decreased, leading to increased competition for food among the goats. This limited the population's ability to grow further, causing it to level off at approximately 100,000 individuals.
As the goat population on the island of Northern Isabela grew rapidly, it reached a point where the available resources, such as food and space, became limited. With a high population density, competition among the goats for these limited resources intensified. This increased competition for food and other essential resources would eventually lead to a decrease in individual fitness, reduced reproductive success, and increased mortality rates among the goats.
As the competition intensifies, it becomes more challenging for the goat population to sustain further growth. The limited availability of resources would act as a limiting factor, preventing the population from continuing to increase at the same rate. This results in a leveling off of the population size, as seen in the graph.
This phenomenon of population growth reaching a plateau due to resource limitations and competition is commonly observed in ecological systems and is known as the carrying capacity of the environment. The carrying capacity represents the maximum population size that a particular habitat or ecosystem can sustainably support.

If you modified the tail of chlorophyll to be polar, which of the following would you expect to happen to light energy?
a. Light would not be absorbed by chlorophyll
b. Light would be absorbed and the electron would remain in an excited state since the chlorophyll would not interact with the membrane reaction center
c. Photosynthesis could still occur because the porphyrin ring is what captures light
d. Light would be absorbed but the energy would be lost as fluorescence/heat since the chlorophyll would not interact with the membrane reaction center
In two paragraphs explain why D is correct and why the others are not?
If the tail of chlorophyll were modified to be polar, D: light would still be absorbed but the energy would be lost as fluorescence or heat since the chlorophyll would not interact with the membrane reaction center.
This is because the tail of the chlorophyll molecule is responsible for anchoring it to the membrane and allowing it to interact with the reaction center. If the tail were polar, it would not be able to properly interact with the hydrophobic membrane and would therefore not be able to transfer the absorbed energy to the reaction center.
Option A is incorrect because light would still be absorbed by the porphyrin ring of the chlorophyll molecule. Option B is incorrect because the electron would not remain in an excited state, but rather the energy would be lost as fluorescence or heat. Option C is incorrect because while the porphyrin ring is responsible for capturing light, the tail is necessary for transferring the absorbed energy to the reaction center for photosynthesis to occur. Without the proper interaction between the tail and the reaction center, photosynthesis cannot occur.

how are these models (the SIM and the diagram) similar and how are they different?
These models (the SIM as well as the diagram) are similar because they both depict the fate of energy storage molecules during photosynthesis. However, they also differ since the SIM model shows the products and reactants (time 1, time 2) in the producer cell, whereas, the diagram illustrates the overall reaction during photosynthesis.
The SIM model shows that carbon dioxide and water (reactants) are present within the chloroplast (Time 1) in a producer cell. It also shows the products formed during the process of photosynthesis, i.e. Energy Storage Molecules (ESM) and oxygen, within the chloroplast (Time 2) in the producer cell.
The diagram, on the other hand, illustrates the overall reaction that occurs during photosynthesis as well as the rearrangement of atoms during this reaction. It represents the reaction for photosynthesis which can be also written as:

describe how muscles of respiration change their activity between inhalation and exhalation
The muscles of respiration change their activity between inhalation and exhalation by altering the volume of the thoracic cavity.
The muscles of respiration change their activity between inhalation and exhalation by altering the volume of the thoracic cavity. During inhalation, the diaphragm and external intercostal muscles contract, causing the thoracic cavity to expand and the lungs to fill with air. The accessory muscles, such as the sternocleidomastoid and scalene muscles, also assist in this process. During exhalation, the diaphragm and external intercostal muscles relax, and the elastic recoil of the lungs and thoracic cage forces air out of the lungs. The internal intercostal muscles and abdominal muscles may also contract to increase the pressure in the thoracic cavity, further aiding in the exhalation process. The coordination of these muscles ensures efficient ventilation of the lungs and delivery of oxygen to the body's tissues.
