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.

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.

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.

Which sentences describe the differences between photosynthesis and cellular respiration?

Check all that apply.

Cellular respiration uses oxygen as a reactant and photosynthesis does not.

x Cellular respiration produces glucose and photosynthesis does not.

Cellular respiration produces excess ATP and photosynthesis does not.

x Cellular respiration stores energy from the Sun in glucose molecules and photosynthesis does not.

Cellular respiration is performed by consumers and photosynthesis is not.

Cellular respiration releases energy from glucose molecules and photosynthesis does not.

Explanation:

The differences between photosynthesis and cellular respiration include the use of oxygen as 1) a reactant in cellular respiration,5)  the role of consumers in cellular respiration, and 6) the release of energy from glucose in cellular respiration.

The differences between photosynthesis and cellular respiration are fundamental to understanding how life processes energy. The correct sentences that describe these differences are:

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose, while releasing oxygen as a byproduct. In contrast, cellular respiration is the process by which living organisms, including both producers like plants and consumers like animals, release energy stored in glucose to produce ATP, which is used for cellular work, and this process requires oxygen while producing carbon dioxide and water as byproducts.

Answer:

A. Both organisms benefit in cooperation, but only one benefits in predation and competition.

In terms of competition, cooperation, and predation Between the two organisms, the third statement is best described. Cooperation benefits both organisms; predation benefits only one, and competition benefits neither.

There are many organisms living in a single ecosystem. These organisms show different relationships, such as prey-predator relationships, mutualism, cooperation, etc.

Mutualism is a positive association in which both organisms benefit. In a cooperation relationship, individuals cooperate with each other to live and for other necessary things such as predation, etc.

Some animals are in a prey-predator relationship in which one organism is killed and another gets the food out of it. In this case, the prey suffers  while the predator benefits. In competition both the involving partner face negative impact of competition. The competition is not beneficial for anyone as both of them are affected by it, and it happens for the territory, etc.

Hence, the third statement is correct, because both organisms benefit from cooperation, while only one benefits from predation and neither from competition.

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.

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.

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).

A homozygous dominant brown mouse (BB) crosses with a heterozygous brown mouse (Bb)

What percentage might be homozygous recessive (bb)?

If we draw a Punnett Square, we get BB, BB, Bb, and Bb.

Answer: 0% We don't have homozygous recessive. 50% is homozygous dominant and the other 50% is heterozygous.

There will be no homozygous recessive offspring. Hence, 0% of offspring will be homozygous recessive.

When at a particular gene locus two identical alleles are present then it is known as a homozygous condition. In this condition, characters are either dominant (BB) or recessive (bb).

When at a particular gene locus two different alleles are present then it is known as a heterozygous condition. In this condition, the recessive allele is suppressed by the dominant allele. Therefore character is always dominant (Bb).

When a homozygous dominant brown mouse (BB) is crossed with the heterozygous brown mouse (Bb), then in next-generation, 50% homozygous dominant brown mouse (BB) is produced and 50% heterozygous brown mouse (Bb).  The cross is attached in the image below.

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.

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.

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.

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.

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.

Answer:

The cell with radius 1

Explanation:

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

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.

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.

They accurately compare the current atmosphere with the previous one, by assessing the amount of atmospheric gases present today, with the amount of atmospheric gases trapped in ice cores that they believe are millennial, that is, they have existed for thousands of years ago.

Explanation:

As we know, it is difficult to compare current characteristics of the planet earth with characteristics that the planet had in the past, thousands of years ago. This is because the ancient characteristics on earth are not fully available to be analyzed, since most of them have been modified over time.

To do this, scientists need to find factors that may have existed thousands of years ago and assess whether these factors have any account of the characteristics of the earth. In the case of atmospheric characteristics, it is common for scientists to compare the current atmosphere with the atmosphere of thousands of years ago, with the assessment of the amount of atmospheric gases trapped in ancient ice cores, with the amount of atmospheric gases present in the atmosphere today.

Scientists compare ancient and contemporary atmospheric compositions through indirect methods, such as analyzing ice cores, tree rings, glacier sizes, pollen counts, and ocean sediments, as well as the chemistry of variously-aged minerals. These factors indicate changes in the atmosphere over time.

Scientists compare the atmospheric composition of today with that of thousands of years ago through various indirect methods of measurement. For example, they analyze ice cores, tree rings, glacier sizes, pollen counts, and ocean sediments. These physical attributes are impacted by changes in the atmosphere and therefore, show patterns overtime.

When an ice core or tree is examined, each layer represents a year and the trapped gases represent the atmosphere during that year. This allows scientists to reconstruct atmospheric composition over thousands of years.

Furthermore, the chemistry of minerals that formed at different times can indicate the amount of, for example, atmospheric oxygen. It's important to note that alterations in Earth's orbit around the sun and the activity of the sun itself also provide insights about the history of Earth's atmospheric composition.
