Explanation:
A student is using a terrarium like the one shown here to study the cycling of
water in an ecosystem.
Which observation would be the best evidence of the water cycle?
O A. Condensation
O B. Predation
O C. Moving animals
O D. Dead plants
Answer:
A- condensation
Explanation:
Condensation would be the best evidence of the water cycle in a terrarium ecosystem. Therefore, option (A) is correct.
What is water cycle?The water cycle is the continuous movement of water between the Earth's surface, atmosphere, and underground. It involves several processes, including evaporation, transpiration, condensation, precipitation, and runoff.
In the water cycle, water evaporates from the Earth's surface into the atmosphere, where it cools and condenses into clouds. These clouds can then produce precipitation, such as rain, snow, or sleet, which falls back to the Earth's surface. Some of this precipitation is absorbed by plants or runs off into rivers, streams, and lakes, while the rest seeps into the ground to become groundwater. This groundwater can eventually be released back to the surface through springs, or it can flow into larger bodies of water.
The water cycle is a vital process for the Earth's ecosystems, as it helps to distribute water and nutrients across the planet and support life. Human activities, such as deforestation and pollution, can disrupt the water cycle and have negative impacts on the environment.

Which of these is the best explanation for why the rock on the ocean floor and the rock on the continent are
NOT the same age?
There has been a lot of erosion on the continent and the older rock has been washed away.
There has been a lot of erosion on the ocean floor and the older rock has washed away.
Due to the movement of the plates, the rocks that make up the ocean floor are pulled inside the earth
more often and are much younger.
Answer:The continental crust is less dense so the oceanic crust subducts back to the mantle. This process explains why the younger rocks are found on the ocean floor. 24.
Explanation:
What is the key activating signal in the TNF receptor signaling pathway that occurs downstream of TNF-alpha binding to the extracellular domain
Answer:
TNF-alpha is expressed as a homotrimer that exerts its activities through binding to two types of receptors: TNFR1 and TNFR2, which are transmembrane glycoproteins characterized by having an extracellular domain with 4 cysteine-rich domains (CRD 1-4) , each with 3 cysteinecysteine disulfide bonds.
Explanation:
TNF-alpha (Tumor Necrosis Factor), which has the characteristic of being a paracrine signaling ligand, is a pleiotropic cytokine that functions as a mediator of immune regulation, the inflammatory response and apoptosis in some cell types. Receptors in this family are involved, with some exceptions, in juxtacrine signaling; that is, both the ligand and the receptor are membrane proteins with extracellular domains through which signaling is established. The cellular responses promoted by TNF are initiated by its interaction with two different types of cell receptors, the type I receptor (55 kDa) and the type II receptor (75 kDa). Both types of receptors are part of the TNF receptor family, members of which include Fas antigen (apoptosis inducer, also called Apo-1 or CD95), CD27 (T-cell activation antigen), CD30 (lymphoma marker Hodgkin) and CD40 (B-cell antigen), which share the characteristic of cysteine-rich sequences in their extracellular domains. This family of cytokines generate cellular responses that include differentiation, proliferation, activation of NFκB and cell death, promoting the aggregation of receptor monomers, that is, they have a transmembrane domain that participates in the solubilization of the receptor and a domain of intracellular death that is involved in signal transduction. The binding of TNF to TNF-R1 induces a signaling cascade through its intracellular death domain, which subsequently leads to the activation of complex I (or inflammatory) of NFkB and proceeds to the transcription of anti-apoptotic genes, pro- inflammatory diseases and apoptosis complex II (caspases).

a. The entire Gorongosa park is 4,000 km². Approximately how large (in km) is the portion of
the park that has been studied?
ASAP PLSS
Answer:
800 km²
Explanation:
If the researchers have studied 20% of the 4000 km² park, to find out how much of the park in km they have studied, all you have to do is find 20% of 4000.
4000 x .20 = 800
800 km² is your answer.
If the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].
What do you mean by the researcher?A researcher may be defined as a kind of person who significantly carries out academic or scientific research in order to find some unrevealed data and information.
According to the question,
The total area of Gorongosa park = Gorongosa park is 4,000 km²
The area which is already studied = 20%.
Now, you have to find the area that is already studied in km. So, you have to calculate the 20% of 4,000 km².
The area which is already studied = 4000 × .20 = 800 [tex]km^2[/tex].
Therefore, if the area of the entire Gorongosa park is 4,000 km². Among which, 20% of the park is already studied, it means 800 [tex]km^2[/tex].

The correct answer is "Two identical DNA molecules are made that contain one original strand and one paired strand."
Explanation:
The word "conserve" refers to the action of preserving an element. Moreover, the prefix "semi" refers to partial. In this context, DNA replication can be considered as a semi conservative process because the original DNA is partially preserved. This is explained in "Each of the two daughter molecules made during replication contain one strand from the parent molecule and one new strand" because this excerpt shows how in the process each of the cells resulting has at least 50% of the DNA of the original cell. This implies replication does not lead to a completely new cell as part of the genetic material is kept. According to this, this process can be considered as semiconservative because "Two identical DNA molecules are made that contain one original strand and one paired strand."

ANSWER QUESTION PLZ TYSM!!
Answer:
Difference: Conductors are materials that permit electrons to flow freely from particle to particle. Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.
Similarities: Both conductors and insulators deal with the electric conductivity of a surface or material. Everything is either a conductor or an insulator. It is a conductor if it readily allows electrons to flow across it, when there is a potential voltage differential between two points on the surface.

color rabbit seemed to camouflage the best in the summer habitat and why?
Answer:
The more an animals color matches their surroundings, the more likely it is for survival. White rabbits fur matches the snow, and brown rabbits fur blend with the dirt
Explanation:
The colors that stand escape the many would be red and blue and the one's camouflage is mostly brown, green, and yellow, swinging on its place and surroundings.
What is the Color rabbit?
The prey that is more delicate in color lasts extended. As the duration goes on, the white prey lasts extended than the blue colors as they blend into their surroundings sufficiently.
The green, red, and orange varied practically extinct over the 3 generations because they could be stained easier and could not blend into their surroundings.
The colors were very necessary for how it influenced the people because the more brilliant the color the more predators it's going to seduce and the colors such as green and brown are more camouflage.
The more an animal's color approximates its surroundings, the more possible it is to survive. White rabbit's fur approximates the snow and brown rabbits' fur in combination with the dirt.
