Explanation:
The universe can be explored using visible and invisible forms of light. These dishes (that detect radio waves from outer space) are part of a much bigger telescope in New Mexico. What is its name? A. Viking B. Voyager C. Very Large Array D. International Space Station
There are 28 radio antenna, which are essentially satellite dishes. Only 27 are in operation at any given time, leaving one to sit out for maintenance. Astronomers using this array were able to observe black holes, and also observe the formation of interplanetary disks, among many other applications as well.
The reason why so many dishes are used is to increase the faint signal that is received from such a long distance away (often lightyears away). The 27 dishes are effectively the same as having a single radio dish that is 36 km (22 miles) in diameter. Having such a impossibly massive satellite dish is not feasible, so it's more practical to go with 27 smaller dishes.

How are the lydias ice and lyric cycles different
Answer:
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
Explanation:
A and B are biotic in nature, C, D, and E are abiotic in nature. In an open system, A produces D and E while B could not produce anything rather depend totally on the D and E produced by A. As the number of A increases, it favours the growth of B, the production of D and E also enhances the growth and development of B.
Answer:
A: Plants
B: Consumers
C: Sun
D: Oxygen
E: food
Explanation:
Abiotic factors refer to non-living things int he ecosystem, whereas the biotic factors are the living things in the environment.
A, in this case, is referring to the plants in the ecosystem, the producers. Plants produce D and E, that is, oxygen and food respectively. B are the consumers in the environment, the herbivores in particular that feed on the plants and rely on it as the only food source. C refers to the sun as the source of light energy for the plants.

For diffusion to occur, which condition must be met?
A concentration gradient must exist.
A hypotonic external environment must exist.
A hypertonic external environment must exist.
Dynamic equilibrium must exist.
Answer:
A concentration gradient must exist.
Explanation:
For diffusion to occur, a concentration gradient must exist. Therefore, the correct option is A.
The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.
Without the use of energy, molecules can be transported from an area of high concentration to an area of low concentration through the process of diffusion. Simple diffusion and Complex diffusion are the two types of diffusion. Diffusion was made easier.

a student placed a stack of rocks on a ramp. she added clumps of soil rooted with live grass. using a garden hose, she then applied a steady spray of water that soaked into the soil, making it heavier. what does the students experiment model
Answer: its C
Explanation:
Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.
A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.
In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.
Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.
Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.
Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.
In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.

It is made up of various components such as chemicals like micro molecule that form the macro molecule, at chemical level the structural composition are organized together to make cells
At Cellular level of organization form the tissue and it is complex to cell but simpler to organ which makeup of various together.

what is the composition of gastric juice and their functions?
Answer:
Mostly HCl, Pepsin, Lipase, Water, and other Electrolytes
Explanation:
The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric acid content, and it is rich in enzymes. As noted above, the stomach walls are protected from digestive juices by the membrane on the surface of the epithelial cells bordering the lumen of the stomach; this membrane is rich in lipoproteins, which are resistant to attack by acid. The gastric juice of some mammals (e.g., calves) contains the enzyme rennin, which clumps milk proteins and thus takes them out of solution and makes them more susceptible to the action of a proteolytic enzyme.
Answers:
It is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. It is found in all vertebrates.
Main function is to inactivate microorganisms.
