Answer:
Explanation:
Continents are the seven main divisions of land on Earth. A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope.
b. The water cycle is constantly repeating on Earth's surface.
c. Water changes form, but the total amount of water remains the same.
d. The water cycle includes many different steps, and each step involves matter.

RNA or Ribonucleic acid is a molecule similar to DNA. It is single-stranded, has nitrogenous base pairs, and a sugar molecule. The RNA can be categorized into mRNA, tRNA, and rRNA.
The correct sequence of nucleotides in the tRNA will be:
U - U - A
In the nucleotide sequencing, the nitrogenous compounds present in the RNA are adenine, guanine, cytosine, and uracil instead of thymine.
The mRNA is a single messenger molecule, which is made from the transcription of DNA molecule. The further process involves the translation in which ribosomes play a crucial role.
In translation, the polypeptide is synthesized by the information delivered by the mRNA. The information in the mRNA is read in the form of a group of three nucleotides, known as a codon.
The codon is then read by the corresponding anticodon region of the tRNA molecule. It makes the set of the anticodon, which is complementary to the codon.
For instance, the mRNA containing the base pairing of A-A-U, the complementary sequence made by tRNA will be U - U - A.
Therefore, the correct answer is U - U - A.
To know more about mRNA and tRNA, refer to the following link:
Answer:
U-U-A
Explanation:
A mRNA molecule is formed as a result of transcription, which then proceeds to the ribosomes in the cytoplasm to undergo translation. Translation is the process whereby an amino acid sequence (protein) is synthesized using the information in the mRNA molecule/sequence. The mRNA sequence is read in a group of three nucleotide bases called CODON. Each codon specifies an amino acid.
This codon is read by another RNA molecule in the ribosome called tRNA (transfer RNA). tRNA contains another set of three nucleotides called ANTICODON, which is complementary to the CODON and responsible for reading the codon in order to carry the corresponding amino acid to the growing sequence.
According to this question, a portion of a messenger RNA molecule contains the base sequence A-A-U, the complementary anticodon sequence of the tRNA would be U-U-A.

Answer: Line A is the enzyme, and Line B is the no enzyme
Explanation:
The reaction rate of a chemical reaction is greatly impacted by the presence of an enzyme. Enzymes are biological catalysts that speed up the chemical reaction by lowering the activation energy required for the reaction to occur. Without an enzyme, the reaction rate may be slow or even non-existent, whereas with an enzyme, the reaction rate can be significantly increased.
In order to compare the reaction rate with and without an enzyme, a graph can be plotted with time on the x-axis and the amount of product formed on the y-axis. The reaction without the enzyme would have a slower rate of product formation and would result in a lower slope on the graph. On the other hand, the reaction with the enzyme would have a sharper rate of product formation and would result in a steeper slope on the graph.
It is important to note that the reaction rate with an enzyme can only be increased up to a certain point, as the enzyme can become saturated with substrate molecules. At this point, the reaction rate will plateau and adding more substrate will not increase the rate of product formation.
Understanding the role of enzymes in chemical reactions is crucial in fields such as biochemistry and pharmacology, as many drugs and therapies work by targeting specific enzymes in the body. By manipulating the activity of enzymes, scientists can alter the rates of chemical reactions and ultimately impact physiological processes.
Step 2 Cell grows in size and other organelles duplicate.
Step 3 Cell wall or membrane forms.
Step 4 Cells separate into two new cells.
Mitosis is a process cell division, where one cell divides into two identical cells. Mitosis consists of four phases -
1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up.
2. Metaphase: Chromosomes line up at the centre of the cell.
3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.
As can be seen, some steps are similar. And the end products in both cases are new cells. In mitosis, however, new cells are part of a multicellular organism while in binary fission, new cells represent new organisms.
Answer: HERNIATION
Brain HERNIATION represents a displacement of brain tissue under the falx cerebri of through the tentorial notch or incisura of the tentorium cerebelli.
Explanation: Brain herniation is a condition of the brain in which tissues of the brain,blood and cerebrospinal fluid shift from the normal position they are in the skull due to high pressure within the skull as a result of brain tumour,trauma to the brain,stroke or bleeding.
Brain herniation results in cardiac and respiratory arrest,loss of consciousness,high blood pressure and loss of brain stem reflexes example blinking and pupils of the eye reaction to light.
