What is the purpose of the structure of a spirillum?
Answer:
The purpose of the structure of a spirillum is to obtain more flexibility, which will facilitate its movement.
Explanation:
Spirillum bacteria are a phylum, the Spirochaetes. And its name is probably because of the spiral shape its body structure has. Due to this body structure, these bacteria have greater flexibility and can move with greater ease and agility. The movement they perform is circulatory wave (usually around the body itself).

what occurs when external vibration match an objects natural frequency.
Resonance occurs when external vibrations match an object's natural frequency, leading to maximal oscillation amplitude. Forced vibrations at this frequency can lead to greater energy transfer and potentially damage the object or structure.
When external vibrations match an object's natural frequency, a phenomenon known as resonance occurs. Resonance in a vibrating system leads to maximal amplitude of the system's oscillations proportionate to the driving force. For example, if a finger is moving up and down at the natural frequency of a paddle ball on an elastic band, the ball will resonate, leading to increasingly larger oscillations.
In a resonating system, the energy from the external force is transferred more efficiently, which can cause larger amplitude oscillations. This is significant as it can lead to dramatic effects, such as a glass shattering when a singer hits the right note, or a bridge collapsing under the influence of steady winds.
Forced Vibrations and Resonance
Forced vibration occurs when an object is made to oscillate by an external force. If this force happens to match the object's natural frequency, the phenomenon of resonance is observed. This can lead to increased amplitude of oscillations, which can sometimes cause physical damage to the structure or object, especially if the resonance continues for a significant period.

The carrying capacity for a species represents the maximum number of _____ an ecosystem can support.
births
new members
deaths
individuals
Answer: The correct answer for the blank is-
individuals.
Carrying capacity for a particular species can be described as the maximum number of organisms/ individuals in a population that can be supported by an ecosystem.
It varies from species to species in a habitat and is guided by several factors ( such as availability of food resources, social requirements, shelter for the species)
There is an increase in the average size of population below carrying capacity ( as resources are abundant) while population size tends to decline ( due to depletion of resources) above carrying capacity
An instructor says that this disease has been nearly eradicated in developed countries. which disease is probably being discussed?
Nowadays, different countries are constantly emerging and expanding their liabilities which may include the field of medicine. The disease that is being discussed by the instructor that is considered nearly eradicated is probably the measles. This disease is caused by Paramyxovirus which is a major respiratory pathogen among infants and young children. Measles is also known as “rubeola virus”, an acute, highly respiratory symptoms and a maculopapular rash that affects the mouth, head, body and extremities. It begins with the appearance of Koplik spots which may end up to some complications like symptomatic encephalitis and subacute sclerosing panencephalitis(SSPE). In order to prevent this type of disease MMR(Measles, Mumps & Rubella) Vaccine is needed. According to some of the reports, it is still common to some of the countries, but WHO campaigns to eradicate the disease worldwide by the year 2020.
Green plants produce their own food during photosynthesis. which of these statements about photosynthesis is true?
A. Water is one product of photosynthesis.
B. Oxygen is one product of photosynthesis.
C. Chlorophy11 is one product of photosynthesis
D. Carbon dioxide is one product of photosynthesis
Answer:
B.
Explanation:
Water is one of the reactants in photosynthesis. It is split into electrons, oxygen, and Hydrogen ions in first reaction of photosynthesis called photolysis of water. Therefore water is not a product.
Carbondioxide is another reactant of photosynthesis that is reduced in the light independent stage of photsynthesis by H+ from photolysis to give Glucose.This reduction takes place in the Calvin cycle, in the presence of enzyme rubisco and substrate ribulose bisphosphate, The product is 2 molecules of 3C-glycerate phosphate, which later oxidized with hydrolysis of ATP, to form 2-Triose phosphate. The latter is converted to glucose, Amino Acids, or fatty acids.
The Pigments for trapping energy in sunlight in the leaf chloroplast is called chlorophyll.It contains photosystems I and II. It is excited with the impact of sunlight absorbed by the photo systems I and II, and the electron is pick up by electron acceptors. The electron is transferred in cascade of reactions which ends with the primary pigments of photosystem I absorbing electron from photosystem II. The primary pigment replaced the lost electron with electron from photolysis of water above.
Oxygen is the by-product of photosyntheis, it is produced when water is split in Photolysis of water.Oxygen is a by-product because it is not needed in subsequent stages of photosynthesis to give the end products.it is given off for cellular respiration in mammals.Therefore this is the correct answer.
The Calvin cycle and the Krebs cycle are referred to as cycles of chemical reactions because they
occur inside organelles.
start over continually.
are part of the carbon cycle.

The Calvin cycle and the Krebs cycle are referred to as cycles of chemical start over continually.
What is Calvin cycle?The Calvin cycle is a set of chemical events that occur in plants as carbon dioxide is reduced or converted into glucose. It is also known as the Calvin-Benson-Bassham (CBB) cycle or the C3 cycle.
The C3 cycle relates to photosynthesis's nighttime adaptation. It is impliedly light-sensitive, and light-dependent processes produce the fundamental energy carriers.
The Calvin cycle, sometimes referred to as the light-independent processes, is the second step in the process of photosynthesis. The Calvin Cycle, also known as the C3 cycle, is the process by which carbon dioxide is converted into carbohydrates. It was discovered by Melvin Calvin.
Therefore, The Calvin cycle and the Krebs cycle are referred to as cycles of chemical start over continually.

Like a panic button, the _____ issues an alert, summoning other parts of the brain that play a role in the experience of fear
Final answer:
The amygdala acts like a panic button in the brain, alerting the hypothalamus and other brain regions involved in the fear response, which includes initiating the fight-or-flight response and releasing stress hormones.
Explanation:
Like a panic button, the amygdala issues an alert, summoning other parts of the brain that play a role in the experience of fear. When you experience anxiety or fright, the amygdala signals the hypothalamus along the medial forebrain bundle, which in turn stimulates the fight-or-flight response. Consequently, the hypothalamus also prompts the release of stress hormones, such as adrenaline and cortisol, through its control of the endocrine system in reaction to amygdala input. These hormones prepare the body to either confront the threat or escape from it.
In addition to the amygdala and hypothalamus, other structures involved in fear response include the locus coeruleus, an area of the brainstem that releases norepinephrine to trigger the fight-or-flight response and has been linked to panic disorder. The fear circuit runs from the central amygdala to the periaqueductal gray in the midbrain, which is sensitive to multiple neurotransmitters and neuromodulators involved in the regulation of fear and the inhibition of these responses by tranquilizers like benzodiazepines.

Throughout most of human history, human population size _____.
Final answer:
Historically, the global human population grew slowly until the Industrial Revolution sparked growth due to advances in sanitation and nutrition. The population boom slowed as developed countries underwent demographic transition, leading to family size decline and lower birth rates. Nonetheless, the global population stands at around 7.5 billion and continues to rise.
Explanation:
Throughout most of human history, the human population size grew very slowly, with fewer than 500 million people on Earth by 1650, a figure that's less than half of India's population in the year 2000. It was not until the Industrial Revolution in the late 1700s and 1800s, that we witnessed a significant increase in population due to improved nutrition and sanitation, which led to lower death rates and increased survival into adulthood.
By the mid-20th century, in developed countries, birth rates declined because children became more of an economic burden than an asset, and families were smaller due to urbanization, agricultural decline, and women pursuing education. This phenomenon is referred to as the demographic transition. Despite the rapid growth that occurred during the industrial period, some countries are now experiencing a population decline. The human population is currently at an all-time high of approximately 7.5 billion and continues to grow, albeit at varying rates across different regions of the world.

what process takes place in meiosis but not in mitosis
Meiosis involves homologous chromosome pairing and crossing over, leading to the formation of genetically diverse haploid gametes, unlike mitosis.
In meiosis, a specialized form of cell division that occurs in sexually-reproducing organisms, two rounds of nuclear division follow a single round of DNA replication. This process results in the formation of four genetically unique haploid cells (gametes), each containing half the number of chromosomes as the original parent cell. The key features of meiosis that do not occur in mitosis are homologous chromosome pairing and crossing over.
During meiosis I, homologous chromosomes pair up and exchange genetic material through crossing over, promoting genetic diversity. In mitosis, no such pairing or crossing over occurs, and the resulting daughter cells are genetically identical to the parent cell, maintaining the same chromosome number. Meiosis plays a crucial role in sexual reproduction, ensuring genetic variation among offspring.

Which physical property do plasmas and gases have in common?
A- They both have charged particles
B-They have the same attractive forces between particle.
C-They have the same space between particles
D-They create magnetic and electric fields
The correct option is A - They both have charged particles.
Plasmas and gases share the property of having charged particles. In the case of gases, some of the particles may be ionized, meaning they have gained or lost electrons and thus carry a charge. However, the majority of particles in a gas are neutral. Plasmas, on the other hand, are composed of a significant number of charged particles, including ions and free electrons, which gives them unique properties such as the ability to conduct electricity and respond strongly to electromagnetic fields.
The other incorrect options are
Option B is incorrect because gases and plasmas do not have the same attractive forces between particles. Gases typically exhibit weak van der Waals forces, while plasmas, due to the presence of charged particles, can experience much stronger electromagnetic forces.
Option C is incorrect because the space between particles in gases and plasmas can vary widely. In a gas, the particles are relatively far apart compared to the condensed states of matter (liquids and solids), while in a plasma, the distance between particles can be even greater due to the repulsion of like charges.
Option D is incorrect because, while plasmas do create magnetic and electric fields due to the movement of charged particles, gases do not inherently create such fields under normal conditions. Only when a gas becomes ionized and turns into a plasma, or when it is placed in an external electric or magnetic field, can it exhibit similar behavior.
