Match the surface to its respective albedo score. fresh snow soil ocean (high-angle sun) ocean (low-angle sun) 0.95 arrowRight 0.2 arrowRight 0.9 arrowRight 0.05 arrowRight Reset Next
Answer:
fresh snow → 0.9soil → 0.2ocean (high-angle sun) → 0.05ocean (low-angle sun → 0.95Explanation:
Albedo is the radiation reflected by the earth´s surface to the universe.
Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.
Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.
The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

Musculo que tiene las características tanto de musculo esquelético como de musculo liso. Se encuentra en el corazón y sus contracciones son involuntarias
Answer:
músculo cardíaco
Explanation:
Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.

truffle
Answer:
✅ C. amoeba
just took the test
The organism that is an animal-like protist is the amoeba.
What are amoebas?Amoebas are a group of single-celled organisms belonging to the phylum Amoebozoa. They are classified as protists, which are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi.
Amoebas are characterized by their ability to move and change shape through the use of pseudopodia, which are temporary extensions of their cell membrane. These extensions allow amoebas to engulf and surround their food, typically consisting of bacteria, algae, or other small organisms.
Amoebas are single-celled protists that move using pseudopodia, which are temporary extensions of their cell membrane. They are classified as animal-like because of their ability to move and capture food in a similar manner to animals.

How can an allele frequency
increase?
A. Allele frequencies always stay the
same.
B. Random mating occurs within the
population
quency
C. An allele becomes more common in a
population.
Answer:
C
Explanation:
Natural Selection can cause micro evolution, or a change in allele frequency over time
An allele becomes more common in a population. So, the correct option is (C).
What is an Allele Frequency?Allele frequency is also known as gene frequency. It is defined as the relative frequency of an allele at a particular locus in a population, expressed as a fraction or percentage. It is the fraction of all chromosomes in the population that carry that allele over the total population or sample size.
It forms the basis of many population and medical genetic studies. Many evolutionary forces change allele frequencies where allele frequencies can be used to trace past evolutionary events.
Allele Frequency is expressed as:
[tex]1 = p^2 + 2pq + q^2[/tex]
p and q each represent the allele frequency of different alleles.
Thus, an allele becomes more common in a population. So, the correct option is (C).

Why did heating the water affect the surface? I need help my mother is making me di science and im so confused :( I doubt this is biology..
Changes in the surface temperature heat or cool the air above, which leads to air movement (wind). Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler surfaces.
An essential amino acid can be synthesized in the body if caloric intake is adequate. cannot be synthesized in the body in sufficient quantity to meet body needs. can be formed in the body from nonessential amino acids. can be synthesized in the body if there is a nitrogen source.
Answer:
cannot be synthesized in the body in sufficient quantity to meet body needs.

1.5mm
15mm
4.7mm
5.3mm
Answer:
1.5mm
Explanation:
According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.
This means that the diameter of the field of view of Mary's microscope can be calculated as follows:
Diameter of each pollen × no. of pollen that fit in
= 0.3mm × 5
= 1.5mm
Hence, the diameter of the field of view of Mary's microscope is 1.5mm.

The lipid bilayer membrane of a neuron is impermeable to charged molecules or ions. To enter or exit the neuron, ions must pass through special proteins called ion channels that span the membrane. Ion channels have different configurations: open, closed, and inactive. Some ion channels need to be activated in order to open and allow ions to pass into or out of the cell. Which ion channels are used in the production of electrical signals (Action Potential) in neurons
Answer:
The correct answer is: in neurons, the most used ion channels in the production of action potentials are the channels that allow fo passage of sodium and potassium.
Explanation:
Neurons must be able to transmit and receive signals in order for the nervous system to operate. Because each neuron has a charged cellular membrane (a voltage differential between the interior and the exterior), the charge of this membrane can vary in response to neurotransmitter molecules generated by other neurons as well as external stimuli. The membrane potential is the difference in total charge between the interior and outside of the cell. This membrane potential exists thanks to the state of ion channels that may or may not allow the passage of certain ions.
A substance called a neurotransmitter allows a neuron to accept input from other neurons. The neuron will transmit the signal to downstream neurons if the input is powerful enough. The opening and shutting of voltage-gated ion channels, which produce a transient reversal of the resting membrane potential to form an action potential, are used to transmit a signal within a neuron (in one direction only, from dendrite to axon terminal). The polarity of an action potential changes across the membrane as it travels down the axon. The signal then activates other neurons once it reaches the axon terminal.
The target neuron is depolarized to its threshold potential (-55 mV) by a stimulation from a sensory cell or another neuron, and Na+ channels in the axon hillock open, initiating an action potential. The neuron totally depolarizes to a membrane potential of around +40 mV after the sodium channels open. As Na+ channels open, the action potential moves along the neuron.
The cell's membrane voltage is "reset" to the resting potential after depolarization is complete. The Na+ channels shut, signaling the start of the refractory phase in the neuron. Voltage-gated K+ channels open at the same moment, allowing K+ to escape the cell. The membrane potential returns to a negative state as K+ ions exit the cell. The cell becomes hyperpolarized when K+ diffuses out of it, resulting in a membrane potential that is lower than the cell's usual resting potential. The sodium channels revert to their resting state at this moment, ready to open again if the membrane potential rises over the threshold potential again.

What is a truck's acceleration if the net external force on the truck is 560 N and it has a total of mass of 1000 kg?
Answer:
0.56m/s²
Explanation:
The above is the correct answer.
Force = mass x acceleration = mg
⇒ F = mg
where F = 560 N, m = 1000kg
∴ g = F/m = 560/1000 = 0.56
∴ acceleration, g = 0.56m/s² (answer)
Force is known to be a push or a pull which actually puts a body to motion or brings a body to rest. It has to do with the interaction between bodies.

Which type of white blood cell is activated by antigens that are bound to antibodies?
monocytes
eosinophils
basophils
neutrophils
Answer:
basophils
Explanation:
Basophils are a class of white blood cells known as granulocyte, which also include neutrophils, eosinophils, and mast cells. These cells (basophils) are generated in the bone marrow as other white blood cells. When stimulated, basophils degranulate to release histamine, proteoglycans, and proteolytic enzymes and thus mediate immune responses. This process of degranulation occurs when a specific antigen binds to the IgE receptor on the basophil. Moreover, basophils may also be activated by inflammatory mediators (e.g., complement factors such as C5a and C3a, chemokines, etc).
