The leaves of a plant fold inward when touched as a way to defend themselves from potential harm. What kind of response do the leaves demonstrate?

Answers

Answer 1

Answer:

Nactic response

Explanation:

The thigmonasty is a kind of response shown by a plant towards touch and vibration stimuli. It is generally produce in response to changes in plants that occur due to turgor pressure within a cell. The plants generally show this kind of response so as to decrease their surface area so that they can be protected by the grazing herbivores. Also some insectivorous plants like Venus fly trap use it to trap insects when they come in contact of the plant.

On the basis of the above explanation, The leaves of a plant fold inward when touched as a way to defend themselves from potential harm is the example of A. nastic response.

Suppose there was a bird that always sat on a horse’s back and ate the insects that would bite the horse. What term would describe the relationship between the bird and the horse?

Answers

Answer: Mutualism

Explanation: The definition of mutualism states " interaction between two or more species where each species has a benefit". The bird is getting food from the insects and the horse is getting the insects removed. Both are benefited.

The relationship between the bird and the horse where the bird eats insects on the horse's back is known as commensalism.

The term that describes the relationship between a bird that sits on a horse's back and eats insects that would bite the horse is commensalism. This is a type of symbiotic relationship where one species, the bird, benefits by getting food, while the other species, the horse, is neither harmed nor helped significantly. Examples of commensalism include cattle egrets that feed on insects disturbed by grazing mammals and spiders that build webs on trees for housing without affecting the tree.

Why is genetic diversity important in a species?

Answers

Final answer:

Genetic diversity is important in a species because it provides the raw material for adaptation and increases the species' potential to survive and evolve in changing environmental conditions. Genetic diversity helps a species to diversify its adaptability to the environment.

Explanation:

Genetic diversity is important in a species because it provides the raw material for adaptation. The future potential for adaptation in a species depends on the genetic diversity held in the genomes of individuals in the population. A species with high genetic diversity is more capable of adapting to changing environmental conditions, while a species with low genetic diversity may be at higher risk of extinction.

Sustained muscle contraction without relaxation between successive stimuli is called

Answers

Answer:

Sustained muscle contraction without relaxation between successive stimuli is called Tetanus

Explanation:

Tetanus is a bacterial infectian that is characterized by sustained muscle contraction without relaxation between successive stimuli. It usually starts with spams in some muscles. The responsible bacteria is called Clostridium tetani. It can be prevented with vaccination. There are different treatment procedures regarding the symptoms you may have.

Final answer:

The state of a muscle continuing to contract without relaxation between stimuli, maintaining a constantly high tension, is referred to as complete tetanus. This occurs when the stimulus frequency is so high that the relaxation phase disappears, causing the contractions to become continuous.

Explanation:

Sustained muscle contraction without relaxation between successive stimuli is referred to as complete tetanus. Tetanus occurs when the frequency of motor neuron signaling increases to a point where the muscular contraction becomes continuous, eliminating the relaxation phase that usually occurs between contractions. This state of perpetual contraction arises when the stimulus frequency is so high it prevents any relaxation between subsequent muscle twitches. As a result in continuous contraction, the muscle is in a state of complete tetanus, a state in which the tension within the muscle is about three to four times greater than that of a single twitch.

A related concept is wave summation, which is the condition that arises when a second twitch occurs before the muscle has completely relaxed from the first twitch. This leads to a stronger second contraction. A series of rapidly occurring stimuli can evoke summed contractions, leading to incomplete tetanus. If these stimuli continue at a fast enough pace, the relaxation phases may disappear entirely, resulting in complete tetanus.

The process of muscle contraction, including twitches and tetanus, is based on the interaction between actin and myosin in the muscle fibers. The strength of a muscle's contraction is determined by the amount of overlap between these two proteins in the sarcomere, which is the basic unit of a muscle fiber.

Compare the surface area to volume ratios of the three spheres representing cells. Which of the three cells if any has the greatest surface area to volume ratio

Answers

Answer:

The cell with radius 1

Explanation:

The cell with radius 1 has the greatest surface area to volume ratio.

Final answer:

The spherical cell with a surface area-to-volume ratio of approximately 1.2 is more efficient at exchanging nutrients and wastes compared to the cubed cell, which has a ratio of approximately 0.86, due to having a higher surface area relative to its volume.

Explanation:

To determine which cell exchanges nutrients and wastes with its environment more efficiently, we compare the surface area-to-volume ratios of a spherical cell to a cubed cell. A spherical cell with a diameter of 5 µm (meaning a radius of 2.5 µm) has a surface area of 4π(2.5µm)2 and a volume of (4/3)π(2.5µm)3. Calculating these, we find a surface area of approximately 78.54 µm2 and a volume of approximately 65.45 µm3, resulting in a surface area-to-volume ratio of roughly 1.2.

In contrast, a cube-shaped cell with a side length of 7µm has a surface area of 6 x (7µm)2 and a volume of (7µm)3. The resulting surface area is 294 µm2, and the volume is 343 µm3, leading to a surface area-to-volume ratio of approximately 0.86.

Therefore, the spherical cell has a higher surface area-to-volume ratio and is more efficient in terms of exchanging nutrients and wastes compared to the cubed cell. This is because a larger surface area-to-volume ratio allows for more surface area per unit of volume for diffusion to occur.

A Since starch and cellulose are composed of identical monomers, the cellular environment where they are located controls their function. B The monomers of cellulose are connected by covalent bonds, making it idea for structural support. C The monomers of starch are connected by ionic bonds, making it ideal for energy storage for plants.

Answers

Answer: The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties.

Explanation:

Starch and Cellulose flare both polysaccharides which are constructed from the same monomer called glucose. The functions they provide in plants are different which includes the following:

- STARCH is used by plants for energy storage because unlike Cellulose, it's formed from glucose units( oriented in the same direction) connected by alpha linkages which can form compact structures that can easily be broken down.

- Cellulose provides structural support for plant cell wall because unlike Starch, it's formed from glucose units( which rotates 180 degrees around the axis of the polymer backbone chain) connected by beta linkages. This pattern gives Cellulose it's rigid features as is allows for hydrogen bonding between two molecules of Cellulose.

Therefore the statement that best describes why starch and cellulose provide different functions in plants is that (The differences in the assembly and organization of the monomers of these two polymers result in different chemical properties).

If the producer has 40,000 kcal of energy and the primary consumer 4000 1 point
kcal, how much energy was passed on? *

Answers

10% energy was passed on if the producer has 40,000 kcal of energy and the primary consumer 4000 Kcal.

The right answer is option 2.

Explanation:

The producer is the initiator of food chain in a food chain and pyramid.

The amount of energy transferred or pass on to the other level or higher level is 10%. The 90% percent energy is being consumed by organism of the trophic level in carrying out metabolic processes, reproduction etc.

The heat gets dissipated only a small amount reaches the other trophic level.

This logic is also called 10% rule of energy transfer.

So, the producer has 40,000 Kcal of energy

primary consumer comes just after producer as it is a herbivore.

so,

[tex]\frac{10}{100}[/tex] x 40000

= 4000 Kcal

Thus 10% of the energy is passed on.

The following question is based on information from Frank M. Frey, "Opposing Natural Selection from Herbivores and Pathogens May Maintain Floral-Color Variation in Claytonia virginica (Portulacaceae)," Evolution58(11), 2004: 2426-37.

Claytonia virginica is a woodland spring herb with flowers that vary from white, to pale pink, to bright pink. Slugs prefer to eat pink-flowering over white-flowering plants (due to chemical differences between the two), and plants experiencing severe herbivory are more likely to die. The bees that pollinate this plant also prefer pink to white flowers, so that Claytoniawith pink flowers have greater relative fruit set than Claytoniawith white flowers. A researcher observes that the percentage of different flower colors remains stable in the study population from year to year. Given no other information, if the researcher removes all slugs from the study population, what do you expect to happen to the distribution of flower colors in the population over time?

a)the percentage of white flowers should increase over time

b)the distribution of flower colors should not change

c)the distribution of flower colors should randomly fluctuate over time.

d)the percentage of pink flowers should increase over time.

Answers

Answer:

The correct answer is option d)"the percentage of pink flowers should increase over time".

Explanation:

In this study it is stated that two factors affect the flower coloration of Claytonia virginica: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.

_________ is an organ of the alimentary canal?

Answers

Answer:

Small intestine

Explanation:

The given question has not provided the options neither they are found anywhere therefore it can be assumed that the examiner is asking the most important organ of the alimentary canal.

The alimentary canal is the hollow tube-like structure formed inside the human which are associated with the digestion of the food material. The main organs of the alimentary canals are the oesophagus, stomach and the intestine.

The intestine is the main organ of the canal as it is associated with the digestion of the complex biomolecules and the absorption of these nutrients.

Thus, the small intestine is the correct answer.

The alimentary canal, part of the digestive system, includes the mouth, pharynx, oesophagus, stomach, small intestine, and large intestine. Its primary role is to nourish the body by processing food and facilitating nutrient absorption.

The alimentary canal is an integral component of the digestive system. Also known as the gastrointestinal (GI) tract or gut, it begins at the mouth and terminates at the anus. The alimentary canal is about 7.62 meters (25 feet) in length during life and extends to about 10.67 meters (35 feet) after death due to the loss of smooth muscle tone. Its primary function is to nourish the body by facilitating the process of digestion and absorption of nutrients. The canal includes several organs modified to suit the body's functional needs, such as the pharynx, oesophagus, stomach, small intestine, and large intestine. It is important to note that food and wastes within the alimentary canal are considered outside the body until absorption occurs, bringing the nutrients into the body's interior.

Molluscan shells are made of three layers, which one names correctly from the outside?

Answers

Answer:

A molluscan shell is made of three layers arranged from the outside to the inside: A) mantle layer, prismatic layer, periostracum.

Explanation:

Final answer:

The molluscan shell from the outside is made up of the organic layer, the prismatic layer, and the nacreous layer, which is the smooth, iridescent layer inside the shell.

Explanation:

The molluscan shells are composed of three distinct layers, which from the outside are named as follows: the organic layer, the middle prismatic layer, and the inner nacreous layer, also known as the mother-of-pearl. These layers are secreted by the mantle, which is a layer of tissue between the shell and the body of the mollusk. This mantle is responsible for secreting the calcium carbonate that ultimately forms the shell. In particular, the nacreous layer is the smooth, iridescent layer that we often associate with the interior of seashells and the formation of pearls.

Mollusks possess a variety of features, including a radula for feeding, and their body plan typically includes a head with eyes or tentacles, a muscular foot, and the mantle. The radula is present in all groups of mollusks except the bivalves.

Answers

Answer:increased CO2 in the oceans raises the acidity of the water which prevent the formation of calcium carbonate which are used by corals to build their skeleton. When this happened organisms like fishes will not have conducive place for their reproduction.

Explanation:

Final answer:

Increase in atmospheric carbon dioxide can lead to ocean acidification, which interferes with coral calcification, causing coral bleaching and detrimental effects on species diversity within coral reef ecosystems.

Explanation:

Effects of Increased Atmospheric Carbon Dioxide on Coral Reefs

As atmospheric carbon dioxide levels continue to increase, one of the significant changes that could occur in a healthy coral reef ecosystem is ocean acidification. This results from carbon dioxide dissolving in ocean water, which lowers the pH and thus increases acidity. Higher acidity levels interfere with the coral's calcification process, essential for building their calcium carbonate structures. This phenomenon can lead to an effect known as coral bleaching, where corals lose their symbiotic algae, causing them to turn white and often die if the algae loss is prolonged.

Such changes to a coral reef ecosystem can have a profound impact on other organisms within this habitat. Since coral reefs serve as crucial sources of food and shelter for a diverse array of marine life, the decline in reef health can lead to a reduction in species diversity and abundance. Predatory fish and other marine animals may decline as their sources of food diminish, disrupting the entire food web associated with the reef ecosystem.

A population of pigs lives on an island together with burrowing termites. Pigs that have the longest snouts tend to survive more frequently than those with shorter snouts. Over time, most of the pig population is made up of individuals that have very long snouts. This is an example of which type of selection

Answers

Answer:

Directional selection

Explanation:

Natural selection is the process which determines the trait of the organism with which a species can evolve. This process can take place in one of the following ways that are stabilizing selection mode, disruptive selection mode and the directional selection.

When nature selects the species with the extreme trait and only one extreme trait is favoured over other than the population shift towards that particular trait and shows the directional selection.

In the given question, the pigs with longer snouts are favoured more than the pigs with another length of snouts therefore nature selects the pigs with an extreme trait and the population shifts towards that trait. This selection is known as the directional selection.

Thus, directional selection is correct.

Final answer:

The scenario describes an example of directional selection where individuals with traits at one extreme of the phenotype spectrum have an advantage, leading to a change in allele frequency in the population over time.

Explanation:

The situation described is an example of directional selection, a mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. Much like the evolution of the peppered moth observed in eighteenth- and nineteenth-century England. The peppered moth that could better blend with the soot-darkened trees due to the Industrial Revolution had higher survival rates. Similarly, those pigs on the island with longer snouts, because they were probably able to access food better than their short-snouted counterparts, were more likely to survive and reproduce, skewing the frequency of the long snout trait in the pig population over time.

If the grasses contain 10,000 kcal, how much of that will a rabbit consume?

A. 10,000 kcal
B. 1,000 kcal
C.100 kcal
D.10 kcal

Answers

The correct answer is B. 1,000 kcal.

To solve this problem, we need to understand the energy flow in an ecosystem. The energy flow through different trophic levels can be represented by ecological pyramids, with producers (plants) at the base and top carnivores at the top.  

The principle of the ecological pyramid is that only about 10% of the energy is transferred from one trophic level to the next. This is due to the second law of thermodynamics, which states that energy transformations are not 100% efficient and some energy is always lost as heat.

In this scenario, the rabbit is a primary consumer, which means it feeds directly on the producers (grasses). The energy transfer from the grasses (producers) to the rabbit (primary consumer) follows the 10% rule. Therefore, if the grasses contain 10,000 kcal, the rabbit will consume only 10% of that energy.

Calculating 10% of 10,000 kcal:

10% of 10,000 kcal = 0.10 * 10,000 kcal = 1,000 kcal

Thus, the rabbit will consume 1,000 kcal from the grasses. This is why option B is the correct answer.
