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.

what parts of a cell are most likely involved with inherited traits?
Chromosomes are most likely involved with inherited traits.
What are Chromosomes?A chromosome is defined as the long DNA molecule which contains part or all of an organism's genetic material. Most chromosomes consist of very long thin DNA fibers coated with packaging proteins where the most important of these proteins in eukaryotic cells are histones.
These structures are found in the nucleus of cells which contain long pieces of DNA. DNA is the material that holds genes and is the building block of the human body.
Chromosomes also contain proteins which help the DNA stay in the proper shape.
Thus, Chromosomes are most likely involved with inherited traits.

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?
Answer:
English is not my native language so sry if there's any grammaticaly mistake
Explanation:
cuz it changes its shape and forme u got that?!
Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.
What do you mean by Lac repressor?Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.
When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.
Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

whats the difference between starch paste and starch milk(long ish answer pls)
Answer:
Starch Paste is basically a mixture of cellulosic materials added by wheat starch and rice. Starch Milk is just milk with starch in it.
Explanation:
Hope this helps!
Starch paste and starch milk are different in their constituents as starch paste contains a mixture of cellulose which is added to rice or wheat whereas starch milk is just raw starch with fibers in it.
What are starch paste and starch milk?Starch paste is a water-soluble adhesive which is primarily used to bond the sheets of paper. It is widely used in paper industry. It is made from the starch of the grains, potatoes, or other plants that are easily available. Before hardening of this paste, starch paste is a highly viscous, gel-like mixture with high moisture content. The starch paste based adhesives adhere well to the cellulosic materials hence used widely in industries.
The waste product formed from the mashed potatoes smuggling with water i.e., the dewatered potato pulp is known as the starch milk. Starch milk is contaminated by small fiber particles such as potato fragments and all the remaining components of potato juice. The starch milk is therefore also known as the raw starch milk.

What is the role of density changes in a convection cycle
Answer:
Explantion
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks. ... Air from above the ocean is colder and more dens
Convection is the transfer of heat caused by a density difference within a fluid. Water becomes less dense and rises as its temperature rises in the presence of a heat source.
What is convection?Convection is a method of moving heat that is also known as a heat transfer mechanism. When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.
Differential heating causes convection currents. Warmer (less dense) material rises, while cooler (more dense) material sinks.
This movement is responsible for the formation of circulation patterns known as convection currents in the Earth's atmosphere, water, and mantle.
Convection is the heat transfer resulting from variations in density within a fluid. In the presence of a heat source, water becomes less dense and rises in density.
Thus, this is the role of density changes in a convection cycle.
