Answer:
Epideral Cells
Explanation:
The parts of a typical leaf include the upper and lower epidermis, the mesophyll, the vascular bundle(s) (veins), and the stomata. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there.
Turn the amplitude down to almost zero and wait for the waves to hit the screen. Why does the screen darken?
When I reduce the amplitude almost to zero and wait for the waves to hit the screen, my screen darkens because it takes longer for the waves to arrive.
What effect does amplitude have on color?The intensity of the color is determined by the amplitude, or the distance between the wave's midpoint and its peak. The more intense and bright the color, the greater the amplitude of the waveform.
Why doesn't changing the amplitude change the color of the light?If you change the frequency of the light, the color changes, but what if you change the amplitude You simply cannot. Photons make up light. All photons with the same wavelength (color) have the same wavelength.

Formation of enterocelous?
Enterocoelous refers to the condition in which the coelom develops from pouches "pinched" off of the digestive system, whereas Schizocoelous refers to the condition in which the body cavity is formed by the splitting of the mesoderm during embryonic development.
What procedure does the coelom of the enterocoelous and schizocoelous designs follow?Unlike Schizocoelous, where the capsule is created either by breaking the capsule or by pouches "pinched" off of the digestive tract, Enterocoelous is an illness in which the coelom originates from pouches "pinched" off of the digestive system.
A method for how certain animal embryos develop is known as schizocoelous or schizocoelic. When secondary heart cavities coeloms are created by breaking a solid mass of pair with polished nickel hardware embryonic tissue, the schizocoely process takes place.

Which statement is true about the appendicular skeleton of the human body?
Answer:
I am pretty sure it is, The consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton. But I am not positive, I hope this helps!!
Explanation:
Option C, It consists of the bones that form the limbs and the bones that attach the limbs to the axial skeleton.
The part of the vertebrate skeleton that has the bones that hold up the body is the appendicular skeleton, which comprises the elements within the limbs, pelvic and pectoral girdle. It holds the bones that produce and uphold the libms and joins them with the axial skeleton. The appendicular skeleton has 126 bones and helps manipulate the upper limbs.
Two patients are in a hospital. One has retrograde amnesia and the other has anterograde amnesia. Explain one similarity and one difference between the two types of amnesias. Then predict how these two patients will interact with each other.
(i already know what each amnesia means i just mostly need the 'predict how these two patients will interact with each other' because its confusing to me)
Answer:
One similarity between retrograde and anterograde amnesia is that they both involve memory impairment. Retrograde amnesia is the inability to recall memories that occurred before the onset of amnesia, while anterograde amnesia is the inability to form new memories after the onset of amnesia.
One difference between the two types of amnesia is the direction of the memory impairment. Retrograde amnesia affects memories that were already stored before the onset of amnesia, while anterograde amnesia affects the formation of new memories after the onset of amnesia.
Given their different types of amnesia, it's unlikely that the two patients will be able to fully understand each other's memory difficulties. The patient with retrograde amnesia may have difficulty remembering events from their past, while the patient with anterograde amnesia may struggle to form new memories. Depending on the severity of their amnesia, the patients may have trouble communicating with each other and forming new memories together. However, their interactions may still be meaningful and they may form a bond based on their shared experiences of memory impairment.

evolutionary significance of bryophytes
The bryophytes, which include mosses, liverworts, and hornworts, have significant evolutionary significance in the plant kingdom despite their relatively small size and simple structure, they played a crucial role in the colonization of terrestrial environments and the subsequent evolution of higher plants.
Here are some key evolutionary significance of bryophytes:
Adaptation to land: Bryophytes are considered some of the earliest land plants.
They were the first plants to transition from aquatic to terrestrial habitats, paving the way for the colonization of land by other plant groups.
They developed strategies to overcome challenges such as desiccation, limited nutrients, and anchorage to the soil.
Moisture retention: Bryophytes have adaptations that enable them to retain moisture.
They possess specialized structures, such as rhizoids and mucilage, that help absorb and retain water.
This ability to retain water and survive in relatively dry environments was an important adaptation for the conquest of land.
Soil formation: Bryophytes, especially mosses, contribute to soil formation.
They can grow on bare rocks and soil, where their rhizoids aid in weathering and breaking down substrates.
Their decomposed remains also contribute organic matter to the soil, enriching its fertility.
Habitat creation: Bryophytes provide habitat and microenvironments for other organisms.
Their dense mats or cushions create shelter, moisture, and temperature buffering for a variety of organisms, including insects, small invertebrates, and microorganisms.
They contribute to the overall biodiversity and ecosystem functioning.
Reproductive strategies: Bryophytes have unique reproductive strategies. They produce spores that can disperse and colonize new habitats.
Their reproductive structures, such as gametophores and sporophytes, exhibit various adaptations that allowed for successful reproduction in terrestrial environments.
Ecological indicators: Bryophytes are sensitive to environmental changes, making them valuable ecological indicators.
Their presence, abundance, and diversity can indicate environmental conditions such as air quality, moisture levels, and habitat disturbance.
Monitoring bryophytes can provide insights into the health and integrity of ecosystems.
Overall, bryophytes played a crucial role in the evolution and colonization of land by plants.
Their adaptations, ecological roles, and evolutionary history make them important subjects of study for understanding plant evolution, ecosystem dynamics, and the colonization of terrestrial environments.

Which factors changed throughout the experiment? Check all that apply
In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.
The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.
The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.
As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.
