QUESTION 8 Why transport system in animals is more complicated than plants?​

Answers

Answer:

The transport system in animals is more complex than in plants due to several reasons:

Specialized Circulatory System: Animals have a well-developed circulatory system, which includes a heart, blood vessels, and blood. This system is responsible for transporting oxygen, nutrients, hormones, and other vital substances throughout the body. In contrast, plants primarily rely on passive transport mechanisms, such as diffusion and osmosis, to move water, minerals, and nutrients through their tissues.

Active Movement: Animals can move from one location to another, which requires a more efficient and rapid transport system. They need to distribute oxygen and nutrients to their cells to support energy production and remove waste products like carbon dioxide. The complexity of animal bodies, including tissues, organs, and systems, necessitates a specialized transport system to deliver essential substances to all parts of the organism.

Increased Metabolic Demands: Animals typically have higher metabolic rates compared to plants. This increased metabolic activity generates more waste products that need to be eliminated. Animals also require a continuous supply of oxygen for respiration, which necessitates an efficient transport system to deliver oxygen to their tissues. Additionally, animals need to regulate their body temperature, which requires the distribution of heat throughout the body.

Specialized Organs and Tissues: Animals have specialized organs and tissues that perform specific functions, such as the lungs for gas exchange, the digestive system for nutrient absorption, and the kidneys for waste removal. These organs require a well-developed transport system to supply them with the necessary substances and remove waste products efficiently.

Rapid Response to Environmental Changes: Animals often need to respond quickly to changes in their environment, such as predators, prey, or changing resource availability. A complex transport system allows for rapid circulation of signals, hormones, and nutrients to enable swift responses to external stimuli.

Blood Cell Specialization: Animals have specialized blood cells, such as red blood cells for oxygen transport and white blood cells for immune response. These cells require a circulatory system to transport them to the appropriate sites within the body, where they perform their functions.

Describe the roles of the pituitary gland and blood vessels in coordinating growth in an organism

Answers

Answer:

The hormones are released into the bloodstream by the pituitary gland and then travel through the blood vessels until they reach the various organs they have an effect on.

Explanation:

for example, stimulates the thyroid gland to increase or reduce the production of thyroid hormones, depending on how much is needed.

Answer:

The pituitary gland is responsible for producing and secreting various hormones that regulate growth in an organism. One of the primary hormones involved in this process is called growth hormone, which stimulates the growth and division of cells throughout the body. This hormone is regulated by other hormones and growth factors, which are produced in response to signals from the brain and other organs.

To ensure that these hormones reach their target tissues and organs, the body relies on a network of blood vessels. These vessels carry the hormones and other signaling molecules to their destinations, allowing them to interact with the cells and tissues that need them. Blood vessels also play a key role in delivering nutrients and other essential molecules to the cells involved in growth and development.

Overall, the pituitary gland and blood vessels work together to coordinate growth in an organism. The pituitary gland produces and releases the hormones that initiate and regulate this process, while blood vessels transport these hormones and other essential molecules throughout the body to ensure that growth occurs in an orderly and coordinated manner.

Different kinds of substances have different properties. Compare and contrast the electrical properties of salts, metals, and acids.

Answers

Salts, metals, and acids are three different types of substances exhibiting unique electrical properties.

Thus, salts are ionic compounds and exhibit electrical properties as they have both positively charged ions and negatively charged ions. They can dissociate in solution into their constituent ions to conduct electricity, but they can not conduct electricity in the solid state.

Like salts, metals also conduct electricity due to their free-moving electrons. They have high electrical conductivity and are used in electrical wiring and other applications. Acids release hydrogen ions when dissolved in water which allows them to conduct electricity because the hydrogen ions move freely and carry an electrical charge when acids are dissolved in water, thereby, exhibiting electrical properties.

To move charges there needs to be a motive or

Answers

To move charges, there needs to be a motive or a driving force that facilitates the flow of electric charges through a conductor. This motive can be provided by various factors and mechanisms.

One of the primary motives for the movement of charges is the presence of an electric field. An electric field exerts a force on charged particles, causing them to move in a particular direction. This force can be generated by applying a voltage difference across a conductor, creating an electric potential difference. The charges will naturally move from an area of higher potential to an area of lower potential, driven by the electric field.

In addition to electric fields, other motives for charge movement can include electromagnetic induction, where a changing magnetic field induces a current in a conductor, and chemical reactions, such as in batteries or fuel cells, where the conversion of chemical energy into electrical energy creates a motive for charge flow.

Ultimately, the motive for moving charges is provided by the presence of a force or potential difference that can overcome any resistances or obstacles in the conductor, allowing the charges to move and establish an electric current.

Predict what would happen if a pika and a kangaroo rat switched environments.

Answers

If a pika and a kangaroo rat switched environments, they might not survive for long due to their unique adaptations to their particular environments.

A pika's adaptation to its habitat includes growing thick fur in winter to conserve heat. In contrast, the desert environment where the kangaroo rat lives is very hot and dry; therefore, its oily fur helps to conserve moisture rather than heat. The pika's thick fur would make it too hot in the desert environment, whereas the kangaroo rat's oily fur would not be sufficient to conserve moisture in the colder environment.

Additionally, pikas get their water from consuming snow whereas kangaroo rats get water from seeds. In a colder environment, snow is readily available, but in the desert, there is no snow. The kangaroo rats might not be able to survive in colder environments if they do not have access to water, and the pika might not be able to survive in the desert without access to snow.

Therefore, it is likely that the adaptations that allowed the pika and the kangaroo rat to survive in their respective environments would make it difficult for them to survive if they were to switch habitats.

4. A piece of potato is placed in an open container of 0.22M sucrose solution. After a few minutes, you measure the mass of the potato again and no mass change has occurred. What is the solute potential the potato cells if the temperature is 27°C?​

Answers

The solute potential of the potato cells in the given scenario is approximately -6.572 atm·L/mol at a temperature of 27°C.

To determine the solute potential of the potato cells in the given scenario, we need to use the formula for solute potential:

Ψ = -iCRT

Where:

Ψ is the solute potential

i is the ionization constant (which depends on the number of particles into which the solute dissociates)

C is the molar concentration of the solution

R is the ideal gas constant

T is the temperature in Kelvin

First, let's convert the temperature from Celsius to Kelvin:

T(K) = T(°C) + 273.15

T(K) = 27°C + 273.15 = 300.15 K

Since sucrose does not ionize in solution, i = 1.

The concentration of the sucrose solution is given as 0.22 M.

The ideal gas constant, R, is approximately 0.0831 L·atm/(mol·K).

Plugging in the values into the formula:

Ψ = -1 * (0.22 M) * (0.0831 L·atm/(mol·K)) * (300.15 K)

Calculating this equation gives us the solute potential of the potato cells.

Ψ = -1 * (0.22) * (0.0831) * (300.15) = -6.572 atm·L/mol

Therefore, the solute potential of the potato cells in the given scenario is approximately -6.572 atm·L/mol at a temperature of 27°C.

In a woodland, the bark on most of the trees was dark gray. Over time, a population of moths that lived in the woodland gradually changed from light gray to dark gray.

Which ,begin emphasis,best,end emphasis, describes how this change in the moth population was the result of natural selection?

Answers

In the given scenario, where the bark on most trees in a woodland was dark gray, and the population of moths that lived in the woodland gradually changed from light gray to dark gray over time, natural selection best explains how this change in the moth population was the result of natural selection.

Natural selection is the mechanism of evolution where the traits that help organisms survive and reproduce become more common in a population over time. The best explanation of how this change in the moth population was the result of natural selection is provided as follows: Initially, the moth population was light gray, and the tree bark was dark gray.

This meant that the light gray moths were easily seen by predators on the dark gray bark, whereas the dark gray moths could blend in with the dark bark, making them difficult to see by predators. As a result, the light gray moths were more vulnerable to predation, whereas the dark gray moths had better survival rates.

This difference in survival rates led to a higher proportion of dark gray moths in the population over time. This change in the moth population from light gray to dark gray was due to natural selection because it involved the differential survival and reproduction of individuals with certain traits.

The dark gray moths had a higher fitness (i.e., ability to survive and reproduce) than the light gray moths, and this led to the gradual increase in the frequency of the dark gray trait in the population. Therefore, this scenario is a classic example of how natural selection can lead to the evolution of populations over time.

In conclusion, the change in the moth population from light gray to dark gray in the woodland was the result of natural selection because it involved the differential survival and reproduction of individuals with certain traits. The dark gray moths had a higher fitness than the light gray moths, and this led to the gradual increase in the frequency of the dark gray trait in the population over time.
