What processes found at a divergent boundary will help form the following rocks?
Answer:
B
Explanation:
What is a divergent boundary:
In plate tectonics, a divergent boundary is a linear feature that exists between 2 tectonic plates moving away from each other.
They can produce rifts, which become rift valleys.
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that magma rises to fill.
Sedimentary rocks form due to deposition, and accumulation
Metamorphic rocks form in a transformation of existing rock to new rock in a process called metamorphism.
Igneous rocks form through the cooling and solidification of magma or lava.
When the filled gaps of magma cool off, it will produce igneous rocks.
Coffee trees grown in the shade of taller forest trees produce fewer coffee beans than trees grown on cleared forestland. However, unlike coffee grown in full sun, shade-grown coffee preserves some habitat for forest birds and other organisms. What is one advantage of growing coffee in the shade?
A. It harms the environment.
B. It provides farmers with greater profits.
C. It costs more than other growing methods.
D. It helps maintain forest biodiversity.
Answer:
d
Explanation:
provides animals with homes letting them breed
It helps maintain forest biodiversity. Therefore, option (D) is correct.
One advantage of growing coffee in the shade is that it helps maintain forest biodiversity. By growing coffee trees in the shade of taller forest trees, farmers preserve some habitat for forest birds and other organisms, which can help to maintain the overall biodiversity of the forest ecosystem.
This is particularly important in regions where forests are being cleared for agricultural purposes, as it can help to mitigate the negative impact on the environment.
While shade-grown coffee may produce fewer coffee beans than trees grown on cleared forestland or in full sun, it provides important ecological benefits that are not captured by purely economic considerations

The oxidase test is another biochemical test used to distinguish aerobic versus anaerobic metabolism in microbes. Research the oxidase test and describe how it is performed. Include examples of oxidase-positive and oxidase-negative microbes in your answer.
Oxidase test is a biochemical test that is used to identify organisms that produce the enzyme oxidase.
Oxidase test is used to distinguish aerobic from anaerobic metabolism in microbes.
Aerobic metabolism is the use of oxygen to generate energy from a food source while anaerobic metabolism is the generation of energy with the absence of oxygen.
The procedure of oxidase test includes:
Place a piece of filter paper in a clean petri dish and add 2 or 3 drops of freshly prepared oxidase reagent.Using a piece of stick or glass rod (not anoxidized wire loop), remove a colony of the test organism and smear it on the filter paper.Look for the development of a blue-purplecolour within a few seconds as shown in colourBlue purple colour signifies oxidase positive organisms which includes Pseudomonas aeruginosa

How does the high specific heat of water help maintain the temperature of earth?
A By heating and cooling more slowly than land or air
B. By heating and cooling faster than land or air
с.
By heating faster but cooling more slowly than land or air
The high specific heat of water help maintain the temperature of the Earth by heating and cooling more slowly than land or air. Thus, the correct option is A.
What is the specific heat of water?The specific heat of an object is the amount of heat which is required to increase or raise the temperature of unit mass of that particular substance through one degree celsius. Specific heat is represented by the symbol 'c'. Its unit in SI system is Joule /(kg °C) and in CGS is cal / (gm °C).
The high specific heat of water helps in regulating the rate at which air changes its temperature, which is why the temperature of the planet change between different seasons is gradual rather than sudden, especially the geographical locations near the ocean.
Therefore, the correct option is A.

birds have feathers, reptiles have scales
only the birds lay eggs on land; the reptiles can only lay their eggs in water
the reptiles have a series of internal air sacs that allow a very efficient extraction of oxygen
birds are endothermic, while reptiles are generally ectothermic
1 pts
Answer:
birds have feathers, reptiles have scales
birds are endothermic, while reptiles are generally ectothermic
Explanation:
The main difference between birds and reptiles is that birds have feathers on their body while on the other hand, reptiles ahve dry skin and have scales. Reptiles are ectotherms, while birds are endotherms. An ectotherm relies on its external environment to regulate the temperature of its body whereas Endotherms are able to regulate their body temperatures by producing heat within the body.

write paragraph about digestion of food in brief
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
according to wikipedia!
Digestion is nothing but breaking down of substances into simpler forms, which the body can use. We eat many things and they have very complex compounds, our body cannot use these compounds. So, different parts of our digestive system breaks down different compounds to simpler forms, so that our body can use it for different functions.

Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity
Complete question:
Receptors trigger one of two effector pathways resulting in changes in neuronal activity. These changes will, ultimately, effect gene expression. Which effector pathway is characterized by ion flux through transmitter-activated channels resulting in an altered membrane potential and neuronal activity?
A. Slow effector pathways
B. Modulated effector pathways
C. Rapid effector pathways
D. NMDA glutamate receptor pathways
Answer:
D. NMDA glutamate receptor pathways
Explanation:
The NMDA glutamatergic receptor is a cationic channel receptor modulated by a ligand that allows the transport of Na+, K+, and Ca2+. Under certain situations, it exhibits particular permeability to Ca2+. The receptor has different regions that are susceptible to modulation by endogenous and exogenous agents. The receptor can be found at most excitatory synapses, where it responds to the neurotransmitter glutamate. During synapsis, the presynaptic membrane releases L-glutamate, which is received by NMDA glutamatergic receptor. The receptor plays a regulatory role because activates signaling cascades that depend on calcium.
These receptors are involved in normal synaptic transmission, in a diverse physiological phenomenon, and might be responsible for neurodegenerative processes.
The NMDA glutamergic receptor is characterized by ion flux through transmitter-activated channels resulting in membrane potential.
What are transmitter-activated channels?Transmitter-activated channels are channels through cell membranes which are activated by binding of transmitters.
An example of a transmitter-activated channels is the NMDA glutamergic receptor.
The NMDA glutamergic receptor is a ligand-gated cationic channel that allows calcium, potassium and sodium ions through it.

Which of the following is a skin sensory receptor for touch?
A) Pacinian corpuscle
B) Meissner's corpuscle
C) Ruffini body
D) free nerve ending
Meissner's corpuscle is a skin sensory receptor for touch.
Meissner corpuscles are responsible for the sense of touch or light pressure, that is, they are very sensitive to the movement of objects on the skin and to very low vibrations.
About Meissner corpuscles:
• They are located on the lips and fingertips and are very sensitive.
• Meissner corpuscles act when there is a soft and light touch, and when vibrations are less than 50 hertz.
• These receptors can be altered when there is the presence of diseases where both thermal and tactile sensitivity are altered.
Therefore, we can conclude that Meissner corpuscles detect fine touch, that is, they are receptors on the skin that are sensitive to low-frequency vibration.
