Answer:
The correct answer is- Nirenberg and Heinrich, 1961.
Explanation:
Experiments by Marshall Nirenberg and Heinrich Matthaei in 1961, began to decipher genetic codes and state about the 64 triplet codons in the genetic code by using mRNA from DNA to translate into specific amino acids in our biological system.
Their experiment helps to decode or crack the code of DNA by establishing the first codon out of 64 triplet codes which are UUU codes for phenylalanine. In the future, the same approach is used to find other amino acids.

Why do cells need to replicate their DNA?
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
DNA is the genetic material, which is found in every living cell. The DNA is made up of a pentose sugar, nitrogenous base, and phosphate backbone.
DNA is a genetic material that transmits the information from parent cell to daughter cell using DNA replication.
DNA replication is an essential process in which the daughter cells inherit information from the parent cell.
Cell division is a process through which a DNA copies its genetic material and delivers it to the newly forming daughter cells.
The genetic information in the daughter cell must contain the same set of rules and instructions to carry out the vital processes. The information is present in the original copied form of DNA from the parent.
Thus, DNA replication is necessary for the continuity of life and similar genetic information presents the daughter cells.

The body of a lichen actually consists of two organisms. An alga and a fungus. The green alga provides food for the fungus through photosynthesis, while the fungus protects the alga and keeps it moist. This type of relationship is known as:
•Symbiosis
•Parasitism
•Decomposition
•Predator-prey
Answer:
symbiosis
Explanation:
it's symbiosis because the fungus and alga are on the body of the lichen, and is providing benefits for one another. This could easily be misinterpreted as parasitism, but that would be when an organism is inside the host and is providing harm rather than goods.

What does mitosis produce?
Four cells with the same number of chromosomes as the parent cell.
Two cells with the same number of chromosomes as the parent cell
Four cells with half the chromosomes of the parent cell.
Two cells with half the chromosomes of the parent cell.
Answer:
Two cells with the SAME number of chromosomes as the parent cell.
Explanation:
Mitosis produces ONE exact copy of a cell's chromosomes (thus, only two cells)
Meiosis produces FOUR half chromosomal cells (sex cells/gametes).

Answer:
The foxes would have brown fur all year long.
Explanation:
The foxes would have brown fur all year because the change in the environment will not occur. If the change not occur in the climatic conditions, then the foxes did not change the colour of the fur so the brown colour remains for all year long. The colour of fur changes when the change in climate occurs so if there is no change in the climate so change occur in fur colour of foxes.

Delta and Alpha are the same distance from the equator, and they are both near the ocean. Using the information in the map, how does the air temperature of Delta compare to the air temperature of Alpha? Why?
The image of this question is missing, so i have attached it.
Answer:
Explained below.
Explanation:
From the image attached, we can deduce that;
- The air temperature of Delta will be warmer than Alpha.
- The reason is because the wind will push ocean water that's turning and following the coasts and thereby making energy to be transferred from the ocean to the air at Delta and also from the air to the ocean at Alpha.
Answer:
I am doing the same test as you, so it is D. warmer than Alpha. The winds push ocean water that turns and follows the coasts. A lot of energy is transferred from the ocean to the air at Delta, and only a little energy is transferred from the ocean to the air at Alpha.

Divergent boundary is the type of boundary or zone depicted in the image.
What is divergent boundary?In plate tectonics, a diverging boundary, also known as a divergent plate boundary, is a linear structure that exists between two moving tectonic plates.Rifts are formed by divergent boundaries within continents and develop into rift valleys over time.A diverging border is formed when two tectonic plates diverge.Earthquakes frequently occur along these boundaries as magma (molten rock) rises from the Earth's mantle to the surface and solidifies to form new oceanic crust. Divergent is the movement of two plates away from each other. Molten mantle rock erupts along the opening, forming new crust. The earthquakes that occur along these zones, known as spreading centers, are small.To learn more about divergent boundary, refer to:

Explain why the use of the term “theory” in science is different from the use of the word “theory” in everyday language.
Answer:
In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature supported by facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena".

La respuesta correcta para esta pregunta abierta es la siguiente.
Las situaciones más comunes en las que los estudiantes usan el teléfono celular de la manera incorrecta son las siguientes.
-Se la pasan perdiendo el tiempo jugando sus juegos de video.
-Se la pasan viendo videos de sus series favoritas.
-Se la pasan escuchando música.
-Se la pasan ch*teando gran parte del tiempo.
-Se la pasan en las redes sociales, entrando a las páginas de los demás.
Todas estas actividades los distraen y no les proporcionan nada productivo. Les quitan el tiempo y no les aportan nada que valga la pena.
Por esa razón, tanto en casa como en la escuela, padres y profesores deben ser muy estrictos en monitorear el uso que los hijos le dan al teléfono celular.

Smallpox is a virus that causes a rash that then turns into painful blisters. The last known case of smallpox was in 1977. What is the best explanation for the eradication of smallpox?
People are exercising more than they used to.
Genetic testing determines who is more prone to smallpox.
There was an increase in antibacterial products.
An effective vaccine was developed.
Answer:
An effective vaccine was developed
Explanation:
(I actually learnt about this is history!)
Smallpox was around 75-100 years before 1977, and people continued to die from it especially when there were severe outbreaks (thousands of people lost their lives). The main technique for vaccination was to make a small cut in the patients arm or wrist, and then to rub a smallpox scab into the open wound (inoculation). However this was not as effective as it sometimes, brought infections into the wound, but the success rate was still pretty high.
Edward Jenner was convinced that there could be a more effective way of vaccinating people against the smallpox. Jenner discovered (from a milk maid!), that those that have been infected with cowpox won't catch small pox, as they are from the same family. Instead of small pox being the vaccine, Jenner used weakened cowpox pus instead. This was much effective as the side effect of having cowpox mild, and the patient made a full recovery.
Jenner put this cowpox vaccine in injections so that an open wound is not needed.
By the 1850's the vaccine was made compulsory, but many were against it: still believing that miasma (foul air) was the cause of the small pox. It was made compulsory or face a fine in the mid 1950's, hence small pox was eradicated by 1977
