Answer:
B. Excretory system
Explanation:
<em>Because the excretory system is made to remove urine which consists of waste materials such as excess salts and water. The kidneys are present in it as well. If there is too much water in the body the excretory system will produce urine with higher water concentration so whiteish urine will be produced and if there is a low amount of water in the body the excretory system will produce urine with lower water concentration so yelloish or greenish urine will be produced</em>
Answer: DNA
Explanation:
A chromosome is a thread-like material with a long structure found in the cell nucleus. It mainly contains DNA and proteins. Due to the presence of DNA in chromosomes, it carries several genes.
The total number of chromosomes in human cell is 46: 44 are non-sex chromosomes while 2 are sex chromosomes
Answer: c. are spliced out of the message.
Explanation: Intron are non-coding portion of the DNA sequence. They do not code for any specific amino acid and are spliced or removed before splicing.
Exons are DNA sequence that code for specific amino acid they are usually left after introns are removed and are joined together before translation into amino acid sequence. Intron splicing can lead to splicing some exons which can lead to formation of an entirely new amino acid or protein.
Spliceosome are enzymes for splicing introns.
Answer: Natural Selection
Explanation:
Natural Selection is the process by which the chances of the fittest organism to survive increases and rest of the organisms has less chances of survival.
The diversity of the organisms increases the survival rate of the organism. The natural selection shows that the fittest organism will have a greater probability to survive.
The more stable the organism more will be the probability of the organism to resist the change.
Answer:
A)Ocean floor evidence of sea floor spreading.
Explanation:
evidence pointing to the steps or process of seafloor spreading and effective plate motion This theory was accepted by many scientist because it depended on hard evidence and could describe most of the modern geological structures such as ocean basins,
What is the tectonic theory?
The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.
What is a tectonic plate?
They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking that makes the ground shake During the earthquake and afterward, the plates keep on shaking until they are stuck again!
