In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark than cones.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

The different forms matter can take are referred to as states or countries.
Answer:
Three States of Matter
Learning Objective
Describe the three states of matter
Key Points
Matter can exist in one of three main states: solid, liquid, or gas
The states of matterThis diagram shows the nomenclature for the different phase transitions.
Solids
A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.
In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. For example, iron has a body-centered cubic structure at temperatures below 912 °C and a face-centered cubic structure between 912 and 1394 °C. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure.
A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing. A solid can also change directly into a gas through a process called sublimation.
Liquids
A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid (water is a well-known exception to this rule). The highest temperature at which a particular liquid can exist is called its critical temperature.
A liquid can be converted to a gas through heating at constant pressure to the substance’s boiling point or through reduction of pressure at constant temperature. This process of a liquid changing to a gas is called evaporation.
Gases
Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small (or zero, for an ideal gas), and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.
A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid).
A supercritical fluid (SCF) is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.
Phase Changes –What does a phase change look like at the molecular level? This video takes a look at the molecular structure of solids, liquids, and gases and examines how the kinetic energy of the particles changes. The video also discusses melting, vaporization, condensation, and freezing.

Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of knowns that were tested. Revise the experimental design by proposing ways to modify the experiment to increase your certainty in the identity of the unknowns
Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is : The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test color, malleability, melting points, and to test how shiny or dull it is. I would propose these to increase the certainty in the identity of the metals. Btw, please mark me brainliest.
Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".
The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
The ligand that activates the g-protein linked receptor is:
Answer:
When a ligand binds to the GPCR it causes a conformational change in the GPCR, which allows it to act as a guanine nucleotide exchange factor (GEF). The GPCR can then activate an associated G protein by exchanging the GDP bound to the G protein for a GTP.

If the environment gets cold, humans will often respond involuntarily by shivering in order to:
a. keep body temperature the same as the external temperature
b. increase body temperature
C. decrease body temperature
d. regulate blood pressure
Answer:
increases body temperature
Explanation:
this is because when you shiver your blood vessels contract which then increases your body temperature
If the environment gets cold, humans will often respond involuntarily by shivering in order to increase body temperature. So, the correct option is B.
What do you mean by Environment?An environment may be defined as anything that is present in the surroundings of living entities that is either biotic or abiotic.
The process of shivering causes the blood vessels to contract and relax at a rapid rate to maintain homeostasis. The signals of rapid contractions are sent by the hypothalamus through nerve impulses.
Therefore, the correct option for this question is B.

which is not involved with an inflammatory Response
A. Fever - increased temperature
B. Slowed blood flow
C. White blood cells move to the area of infected
D. inflammation in area
This is an inflammatory reaction to an infection in the body. Option D is correct.
What is the inflammatory response?When tissues are harmed by toxins, germs, trauma, heat, or any other cause, the inflammatory response (inflammation) ensues. A fever is induced by the body's attempt to destroy any infections with heat.
Histamine, bradykinin, and prostaglandins are among the substances released by injured cells. Because of these substances, blood vessels leak fluid into the tissues, producing swelling.
White blood cells migrate to the affected location to destroy any germs. Because white blood cells are primarily intended to aid in the killing of infections, sending white blood cells to destroy the pathogen is an inflammatory reaction.
Finally, inflammation results from the body's attempt to cleanse the contaminated region of microorganisms. Similar to the label “inflammatory,” the body will frequently create inflammation in an attempt to cleanse the body of any undesirable infections.
Therefore, option D is correct.

PLEASE ANSWER ASAP.
Explain what friction, corollas, and a low pressure gradient does to an air parcel. IF YOU CAN PLEASE GIVE A SHORT ANSWER.
Answer:
sorry big answer Answer with Explanation:
Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.
Air parcel - refers to a body of air that is "imaginary."
Pressure gradient - the change in pressure across a given distance.
Pressure gradient force - the net force that is being directed from high pressure to low pressure.
When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.
However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.
Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."
When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.
