what is the purpose of this process?
A. to replicate the DNA of an organism before cell division
B. to synthesize amino acids used to unzip strands of DNA and copy the genetic code
C. to translate the genetic code into a specific sequence of amino acids
D. to assemble nucleotides in an mRNA chain along a DNA template
Answer:B
Explanation:
i took it
The main objective of the given process is to translate the genetic code into a particular amino acids sequence.
What is translation in molecular biology?The given diagram signifies the process of translation, that is, the synthesis of protein. In the process, the genetic code carried from the nucleus via the process of transcription, which is producing a complementary sequence of mRNA is converted or translated.
The process of translation completes in three fundamental stages, that is,
InitiationElongationTerminationIt is terminated with ribosomes, that is, a machinery, which constructs peptide chain by combining mRNA with it. The tRNA brings the accurate amino acids to the ribosome to produce peptide chain based on the mRNA code.
Thus, the correct statement is option C.

The table below shows the half-lives of four radioactive materials. Radioactive material Half-lives Bismuth-212 60.5 seconds Sodium-24 15 hours Iodine-131 8.07 days Strontium-90 29 years Which of these materials will decay the slowest to one-fourth of its original amount? Bismuth-212 Sodium-24 Iodine-131 Strontium-90
Answer:
Strontium
Explanation:
The materials that will decay the slowest to one-fourth of its original amount is Strontium-90. The correct option is D.
What are half-lives of radioactive materials?The half-life of a radionuclide is the amount of time it takes for half of its radioactive atoms to decay. A good rule of thumb is that you will have less than 1% of the initial amount of radiation after seven half-lives.
Strontium-90 is considered hazardous waste. Because of its 29-year half-life, it can take hundreds of years to degrade to negligible levels. Water and food contamination may raise the risk of leukemia and bone cancer.
Strontium-90 has a half-life of 29 years (the time it takes for half of the strontium to emit radiation and transform into another substance).
Therefore, the correct option is D. Strontium-90.

Plants are the primary producers in ecosystems on land. The primary producers, who carry out photosynthesis, in aquatic (water) ecosystems are
fish
algae
phytoplankton
Both algae and phytoplankton
Answer:
Both algae and phytoplankton
Explanation:
In the aquatic ecosystems, both algae and phytoplankton are producers and on land, plants are the primary producers.
The primary producers provides food for the whole ecosystem.
During photosynthesis these producers are able to take up inorganic compounds and synthesize organic molecules. They use carbon dioxide and water in the presence of sunlight to produce glucose and oxygen gasThe glucose is the food on which the ecosystem depends on Algae and phytoplankton produces food this way too.A student wanted to study the amount of mold growing on pizza at different temperatures. In the experiment, the student set up four identical p and light conditions are shown in the data table below. Data Table Variables Pan 1 Pan 2 Pan 3 Pan 4 Temperature -10°C 0°C 15°C 30°C Light conditions kept in darkness kept in bright light kept in darkness kept in bright light What was one error made with the four pans of pizza when setting up this experiment? The pizzas were different sizes. The pizzas had different ingredients. The pizzas were at different temperatures. The pizzas received different amounts of light.
Answer:
The pizzas received different amounts of light.
Explanation:
In the experiment, the student sets up four identical p and light conditions, and the growth of the mold depends upon the lights falling on them, so here the error is that the different pizzas receive differing lights that affect the mold growth.
What is the significance of the mold growth on the food?Mold and bacterial growth on food indicate that it is infected, posing health risks from mild to severe. Mold can produce toxic compounds called mycotoxins, which can be harmful to human health when consumed in large quantities, as well as cause economic losses for food as it degrades.
Hence, in the experiment, the student sets up four identical p and light conditions, and the growth of the mold depends upon the lights falling on them, so here the error is that the different pizzas receive differing lights that affect the mold growth.

HELP ASAP PLS!!!! Cystic fibrosis is an inherited genetic disorder that affects the digestive system and the lungs. If a mother carries a recessive allele for a genetic disorder, such as cystic fibrosis, under what circumstances will her children inherit the disorder?
A) The children’s father must also carry the recessive allele.
B) The mother’s father must also carry the recessive allele.
C) The paternal grandfather must also carry the recessive allele.
D) The children must be female like the mother to inherit the disorder.
Answer:
A
Explanation:
For a recessive gene to affect the child they must inherit two recessive alleles because if a dominant allele is inherited than the dominant trait will be the one that is expressed in the child. The only way to get two recessive alleles is to inherit one from both parents so the father must also carry the recessive allele. This means A must be the correct answer.

Complete the following sentence: Oxygen is taken into cells by the process of.....
Oxygen is taken into cells by the process of simple DIFFUSION.
Simple diffusion is a cellular process by which small molecules (e.g., oxygen and carbon dioxide) pass across the plasma membrane and thus can enter and leave the cell.Simple diffusion always occurs in favor of a concentration gradient, i.e., from a region of high concentration to a region of low concentration.For example, oxygen (O2) molecules move from a region of high concentration in the lungs to a region of low concentration in the blood.This process (diffusion) does not require energy to move molecules across biological membranes.In conclusion, oxygen is taken into cells by the process of simple DIFFUSION.
