Answer:
If the boundary between the cold and warm air masses doesn't move, it is called a stationary front. The boundary where a cold air mass meets a cool air mass under a warm air mass is called an occluded front. At a front, the weather is usually unsettled and stormy, and precipitation is common."
Explanation:
Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Answer:
Tissues
Explanation:
Tissues are organized group of cells carrying out specific coordinated functions. They are organizational structures that lies between cells and organs. A group of cells binds together using specialized proteins forming a tissue, furthermore, a group of different tissues are the building blocks for organs and plant structures creating a complete system.
Natural selection is the process in which some organisms that show better adaptation to the environment are more likely to produce an offspring. In the case of the exercise, the answer is:
b. Some tuna live in the Pacific Ocean. They are fast, so they are likely to survive and pass on their genes.
It means that as they are better adapted to that environment due to the fact they are fast swimmers, they are likely not only to survive, but to pass their genes and produce offsprings.
Answer: Base pairs occur when nitrogenous bases make hydrogen bonds with each other.
Explanation: Each base has a specific partner: guanine with cytosine, adenine with thymine (in DNA), The hydrogen bonds are weak allowing it to "unzip"
