RNA code.
TCG GGG CTA ATC AAG
The transcribed code for the DNA as complementary to the RNA code is AGC CCC GAU UAG_ UUC . Th the option D is correct.
What is the RNA code?The RNA code is made of four nucleotides that are adenine, guanine, the cytosine, and the uracil. The code makes a unit known as a codon which forms the amino acid. The RNA consists of a code that is kept by the cell DNA and signals the formation and end of the protein synheis.

cual es la diferencia netre los cloroplastos y la cianobacteria si ambos son bacterias fotosinteticas???
Answer:
Encontré esto en un texto de microbiología, tal vez sea útil.
Explanation:
"Las cianobacterias y los cloroplastos de las plantas tienen ambos fotosistemas, mientras que las bacterias fotosintéticas anoxigénicas sólo utilizan uno de los fotosistemas. Ambos fotosistemas son excitados simultáneamente por la energía luminosa. Si la célula requiere tanto ATP como NADPH para la biosíntesis, entonces llevará a cabo una fotofosforilación no cíclica".
Si estoy equivocado, pido disculpas. También lo he sacado de un traductor así que si suena mal también me disculpo por ello.

6. explain the relationship between temperature and pressure. why do you think this occurs?
Answer:
The pressure of a given amount of gas is directly proportional to the temperature at a given amount of volume. When the temperature of a system goes up, the pressure also goes up, and vice versa.
Explanation:
This occurs because of the pressure temperature law. (or also known as the Gay-Lussac's law)
Describe what occurs in each phase of mitosis.
Prophase -
Metaphase -
Anaphase -
Telophase -
Cytokinesis -
( please do not plagiarize )
Answer:
prophase- the first phase of mitosis, in which the chromatin in the cell coils into chromosomes that can be seen
metaphase- the second phase of mitosis, in which the chromosomes that were doubled become attached to the spindle fiber by their centromeres
anaphase- the third phase, where centriomeres are split apart and sister chromatids are pulled to opposite poles of the cell
telophase- the final stage of mitosis, in which sister chromatids are separated and contain identical copies of DNA
cytokinesis- a process the divides the cytoplasm and plasma membrane of a cell, resulting in two identical cells that contain their own DNA, nucleus, nuclear membrane, and plasma membrane

A comparison of the age of the Earth obtained from radioactive dating and the age of the Universe
based on galactic Doppler shifts suggests that?
A) the Earth was formed after the Universe began
B) the Earth is immeasurably older than the Universe
C) the two dating methods contradict one another
D) The Earth is about the same age as the Universe
A comparison of the age of the Earth obtained from radioactive dating and the age of the Universe based on galactic Doppler shifts suggests that the Earth was formed after the Universe began.
Why do geologists use the radiometric age of meteorites as a guide to the age of the solar system?The meteorites have been isolated in the cold vacuum of space since their formation, so they have seen no significant heating since the time of their formation.
What is the age of the Earth accepted by most scientists today?Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.

Imagine the scenario. All of the rocks used for shelter by certain reptiles are removed from a desert ecosystem. How will the removal of the rocks affect the reptiles?
Answer: The reptiles population will decrease
Explanation:
On the removal or rocks from desert ecosystem, the reptiles will not be able to survive and can become extinct.
What is desert ecosystem?Deserts are desolate areas of land with extremely high or low temperatures, little or no rainfall, and little or no vegetative cover.
Deserts are illustrations of terrestrial ecosystems that can be discovered all over the world. Not all deserts are plain, nor do they all have cacti or oases.
One of the most crucial biomes is the desert. Our planet has 15 different types of mineral deposits, 13 of which are found in deserts.
As a result, the desert is vital for mineral resources as well as the local and global economies.
As it is mentioned that the rocks are used for shelter by reptiles, they cannot survive if these shelters are taken away from them. In this case it is possibility that they can go extinct.
Thus, this is the effect that occurs due to removal of the rocks from desert.

Explain how genetic mutations may result in genetic and physical variations differences) within a population.
Answer:
The correct answer is - Mutations produce different versions of genes.
Explanation:
Mutations are the changes in the gene or DNA of an organism that leads to the production of different version of genes and proteins. Mutations result in genetic variation or physical variation within the population as it introduces new alleles in the populations.
Mutations introduce or remove various versions of genes called alleles within a population and increases genetic variation. These changes in the genes are the source for new genetic variation. Genetic or physical variation does not occur without mutations.
