Amino acids are (relatively) small molecules with a similar chemical structure. All of them have 2 carbon atoms connected to a nitrogen atom. This similar structure allows them to combine in long chains to make macromolecules called proteins.
How many different amino acids are there?
A. 4
B. 20
C. 5
D. Thousands
Answer:
The correct answer is 20...
Explanation:
The name of these 20 common amino acids is as follows: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalaine, proline, serine, threonine, tryptophan, tyrosine, and valine. Alanine.
Although their is 20 altogether their is only 9 main essential ones:
The 9 essential amino acids are leucine, iso-leucine, valine (all BCAAs), lysine, histidine, phenylalanine, methionine, threonine, and tryptophan. Essentials amino acids are important because they serve as the "building blocks" for muscle protein. They are also are what makes a protein a "complete" protein.

Explanation:
what changes were most likely caused by a shift in earth's continents?
Answer:
The earth’s crust is broken into separate pieces called tectonic plates (Fig. 7.14). Recall that the crust is the solid, rocky, outer shell of the planet. It is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. Both types of crust rest atop solid, upper mantle material. The upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.
Each tectonic plate is free-floating and can move independently. Earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. The term fault is used to describe the boundary between tectonic plates. Most of the earthquakes and volcanoes around the Pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. The motion of plates can be described in four general patterns:
<p><strong>Fig 7.15.</strong> Diagram of the motion of plates</p>
Collision: when two continental plates are shoved together
Subduction: when one plate plunges beneath another (Fig. 7.15)
Spreading: when two plates are pushed apart (Fig. 7.15)
Transform faulting: when two plates slide past each othe

tại sao lại có sấm sét
Khi hai đám mây tích điện trái dấu lại gần nhau, hiệu điện thế giữa chúng có thể lên tới hàng triệu vôn. Giữa hai đám mây có hiện tượng phóng tia lửa điện và ta trông thấy một tia chớp. Vài giây sau ta mới nghe thấy tiếng nổ, đó là sấm (do vận tốc ánh sáng nhanh hơn vận tốc của tiếng động nên ta trông thấy tia chớp trước). Khi đám mây dông tích điện đi gần mặt đất tới những khu vực trống trải, gặp một vật có độ cao như cây cối, người cầm cuốc xẻng… thì sẽ có hiện tượng phóng tia lửa điện giữa đám mây và mặt đất. Đó là hiện tượng sấm sét.

Answer:
i) Rusting occurs the least in tubes 2 and 3 because either of air and water which are necessary for rusting is absent in the two tubes respectively.
ii) Rusting occurs most in tube 1 because both air and water which are necessary for rusting are present.
Explanation:
Rusting is a chemical change which involves a redox reaction. During the process of rusting, metallic iron is oxidized to hydrated iron (iii) oxide by oxygen present in air.
For rusting to take place effectively, each of these three factors mist be available: metallic iron, oxygen and water.
In the figure above, the iron nails in the three tester tubes will rust to different extents based on the availability of the three factors.
In test tube 1, the iron nails will rust the most because all the three factors: metallic iron, oxygen present in air, and water are abundantly present.
In test tube 2, the iron nails will rust the least or not at all because boiling of water removes dissolved oxygen from water and the oil layer above the boiled water prevents entry of oxygen from air. Thus, the nail do not rust because one of the three factors for rusting to take place, in this instance, oxygen is absent.
In test tube 3, the iron nails rusts the least or not at all as well because moisture or water is absent. Calcium chloride, a drying agent removes all the moisture from inside the tube. Hence, even though air is present, rusting do not occur as there is no moisture or water present.

Which phrase describes the relative age of a rock?
Answer:
Uses the law of superposition to determine which rock is older or younger.
Explanation:
Relative age refers to the age of the rock when compared to other rocks. The law of superposition was developed by Nicholas Steno. In this process, you determine which rock layer is older or younger in terms of the sequence they were laid out or layers were formed. This law states that the lower the layer, the older the rock layer is as compared to those on top of it.

Label the following topographic map. Click on a label below the map to select it, and then click on the appropriate box on the map to place the label. (Increments for contour lines is 50 feet).
Choices:
River Flow East
Depression
2650 feet
Sleep Area
Based on the information, it can be inferred that the concepts are organized from left to right as follows: Depression, Sleep area, River Flow East, and 2650 feet.
How to identify the correct space for each concept?To locate each concept in the correct space we must know how to read a topographic map. In this case, the depression would be the first concept because in the shaded area the contour lines are shown very close, this is generally related to a depression area in which the slope is very pronounced.
On the other hand, the sleeping area is at the top of the mountain at the bottom of the image because a flat region is shown on the top of the mountain.
Additionally, the blue line through the topographic map represents a river so this could be labeled River Flow East. Finally, the contour line that is at 2650 feet high would be the last space considering that each line represents an increase (or decrease) of 50 feet.

What word is used to describe plant cells placed in a hypotonic solution?
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

Answer:
B
Explanation:
Organisms produced by sexual reproduction have two parents and are genetically similar to both but not identical to either. it produces variation in the offspring. the species can adapt to new environments due to variation, which gives them a survival advantage.
