The Calvin cycle can be best described as a non light-dependent (since they do not directly require light) reaction of photosynthesis
The Calvin cycle, also known as the dark reactions, bio synthetic phase, light-independent reactions, or photosynthetic carbon reduction (PCR) cycle, is a chain of chemical processes that produces glucose from carbon dioxide and hydrogen-carrier molecules. All photosynthetic eukaryotes as well as many photosynthetic bacteria contain the Calvin cycle. These reactions take place in the stroma, the fluid-filled area of a chloroplast that is not covered by the thylakoid membranes, in plants .
The Calvin cycle generates sugars for usage by the plant using the chemical energy of ATP and the reducing power of NADPH from light-dependent processes.

The results of zajonc's study on cockroaches and social facilitation showed __________.
The results of zajonc's study on cockroaches and social facilitation showed
similar results in humans. This led to his theory of social facilitation.
Moreover, Social facilitation is a phenomenon in which people show increased levels of effort and performance when in the presence of others whether real, perceived, implied, or virtual compared to their level of effort and performance when alone.
In addition, social facilitation is thought to involve three factors, including physiological factors, cognitive factors, and affective factors, which are anxiety and self-presentation. A tendency to perform simple or well-rehearsed tasks better in the presence of others than alone. Social inhibition. The tendency to perform complex or difficult tasks worse in the presence of others is called social facilitation.

after a meal, both insulin and glucagon are secreted into the blood stream. what is their relationship?
Together with the hormone insulin, glucagon regulates blood sugar levels and helps to maintain target ranges. Insulin is produced to prevent blood sugar levels from increasing too high (hypoglycemia) while glucagon is released to prevent blood sugar levels from falling too low (hyperglycemia).
The pancreatic islets of Langerhans' alpha cells release the peptide hormone known as glucagon. The best-known effect of glucagon is to promote glucose synthesis in the liver and hence maintain appropriate plasma glucose concentrations. Hypoglycemia is physiologically the most powerful secretory stimulation. The metabolism of hepatic lipids and amino acids is also influenced by glucagon, which may lead to an increase in resting energy expenditure.
The INS gene in humans encodes insulin, a peptide hormone generated by beta cells of the pancreatic islets. It is regarded as the body's primary anabolic hormone.

Scientific researchers discovered agents that behaved like bacteria causing diseases such as rabies and hoof-and-mouth, but were much smaller. It became the general view that viruses were biologically "alive." This perception changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function. It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell. Viruses exist in two distinct states. When not in contact with a host cell, the virus remains entirely dormant. During this time there are no biological activities occurring and the virus is nothing more than a static organic particle. Viruses can remain like this for extended periods of time, waiting to come into contact with the appropriate host. When the virus comes into contact with a host, it becomes active, reacts to its environment and/or host and directs its efforts toward self-replication. The viral goal now is to produce more viruses to attack host cells.
The characteristics of life: many are listed in the passage describing viruses. One important piece of evidence arguing against life for viruses is implied by the passage; not stated directly. Viruses are not living, because, as implied by the passage, they
A. Lack a nucleus
B. Have no DNA
C. Are not cellular
D. Do not reproduce
According to the given passage, viruses are not living because they (C) do not have a cellular organization.
Viruses lack a cellular organization which is a basic feature of all living organisms. A virus is a nucleoprotein, with the genetic material enclosed by a protein coat. The genetic material could be either DNA or RNA. The genetic material is responsible for causing infection in the host.
Viruses are inactive outside their specific host cell. They are non-cellular organisms. They possess an inert crystalline structure outside the living host cell. The protein coat of a virus, i.e. capsid, serves as a protective covering for the genetic material.

what is the effect energy is transferred through the circulation of heated molecules?
Kinetic energy is the energy that is transferred through the circulation of heated molecules.
What is the effect of the transfer of heat energy?If two bodies at different temperatures are conducted together, energy is transferred i.e. heat flows from the hotter body to the colder. The effect of this transfer of energy normally, but not always, is an increase in the temperature of the colder body and a reduction in the temperature of the hotter body. This is called conduction and is a very effective method of heat transfer in metals. However, air conducts heat poorly. Heat transfer is defined as the process in which the molecules are moved from a region of higher temperature to a lower temperature.
So we can conclude that Conduction is the transfer of heat energy from one matter to another or within a substance.

O D. pathway that involves taking in heat from the environment at each step.
In both photosynthesis and cellular respiration, the energy is ultimately derived from the Sun is a one-way process. Option C.
The plant captures mild strength and releases oxygen, that is finally ate up in cell respiration. Thus, the sun is the final supply in each the reaction. The strength is in the long run derived from the sun; this method is usually termed as a one-manner method.
Photosynthetic cells contain chlorophyll and different mild-touchy pigments that seize sun strength. In the presence of carbon dioxide, such cells are capable of convert this sun strength into strength-wealthy natural molecules, inclusive of glucose.
Through the method of cell respiration, the strength in meals is transformed into strength that may be utilized by the body's cells. During cell respiration, glucose and oxygen are transformed into carbon dioxide and water, and the strength is transferred to ATP.

when an action potential reaches the end of an axon, the depolarization causes what ionic movement in the presynaptic cell?
Where the potential of the cell is higher than the resting potential, this results in the inward flow or influx of sodium ions or cations. When the action potential peaks, the sodium channels shut while the outflow of potassium happens.
Neurotransmitters are used by neurons to communicate. Neurotransmitters are released by the action potential as it develops inside the cell and assists in the transmission of impulses from one neuron to another.
The permeability of the voltage gated ion channels, as well as the existence of the myelin sheath, are in an appropriate state. Once the action potential is set off, the neuron's depolarization (2) causes sodium channels to open, allowing sodium ions to enter the cell and creating a net positive charge in the neuron in comparison to the extracellular fluid.

The answer is a) 3,5,1,4,6,2. Muscle contraction is defined as the muscle response to a stimulus that involves the interaction of the contractile proteins actin and myosin in the presence of calcium.
The correct sequence of muscle contractions is:
3. Calcium ions are released from the sarcoplasmic reticulum
5. Calcium ions binding to Troponin
1. Myosin Bridges Bind Actin
4. The myosin head pivots towards the center of the sarcomere
6. Myosin heads bind to ATP molecules and are detached from actin filaments
2. Free myosin head cleaves ATP.
The movement of muscle shortening occurs when the myosin head attaches to actin and actin is pulled inward. This action requires energy provided by ATP. Myosin binds to actin at the binding site of the globular actin protein. Myosin has another binding site for ATP where enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy.
