Chemical reaction
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. The reactants are usually converted to a new product entirely.
The rate of reaction or speed of reaction for a reactant or product is defined as how fast or slow a reaction takes place.
The reaction is always faster at higher temperature. Chemical reactions typically occur faster at higher temperatures.
Since the reactants is heated, the temperature is also increased which invariably leads to higher temperature.
Therefore, if the reactants are heated the reaction usually happens faster

Carbon dioxide is carried in blood plasma.
Human blood also contains red blood cells and white blood cells.
Explain how the structure of red blood cells and white blood cells is related to their function.
(6 marks)
Answer:
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
Blood is important for regulation of the body’s pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Blood is made of of several components, including red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum.

Paul and Jessica are making a model of an animal cell. What should they show going into and out of the cell in their model?
Answer:
Water, carbon dioxide, and oxygen.
Explanation:
It's kind of like the lungs in your respiratory system! It takes in oxygen and submits carbon dioxide out. However, in this case, the cell membrane decides what can come in and what can't. Water, carbon dioxide, and oxygen are essential for cells which is why the cell membrane allows them to cross. This is what Paul and Jessica should show in their model.

Why is tRNA called Transfer RNA?
A. Because it is responsible for transferring the protein out of the cell.
B. Because it is responsible for transferring the protein-building instructions to the ribosome.
C. Because it is responsible for transferring the right amino acid to the ribosome to create the protein.
Answer:
C
Explanation:
When a tRNA recognizes and binds to its corresponding codon in the ribosome, the tRNA transfers the appropriate amino acid to the end of the growing amino acid chain.
Answer:
C. Because it is responsible for transferring the right amino acid to the ribosome to create the protein.
Explanation:
The tRNA is known as the Transfer RNA because it is responsible for transferring the right amino acid to the ribosome to create the protein.

In the Linnaean system of classification, camels are members of the order Artiodactyla and the family Camilidae. Llamas are also members of
the family Camilidae. Based on this information, are llamas members of the order Artiodactyla?
а No, because every family member is classified into a different order.
b Maybe, because families and orders are separate and unrelated taxa.
с Maybe, because some but not all family members are classified in the same order.
d Yes, because all family members are classified together in the same order.
Answer:
The correct answer is - Yes, because all family members are classified together in the same order.
Explanation:
In the Linnaean system of classification, there are 7 taxa that are kingdom, phylum or division, class, order, family, genus, species. In these taxa, the kingdom is most inclusive and species is least inclusive taxa.
Order is more inclusive than the family which means various organism families make the order. If a family all the members are classified under the same order. Order have different families and each family have a different genus and so on.

6. Plates slide past one another at ________________________ plate boundaries.
Answer: When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed.
Explanation: No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault. The transform fault boundaries connect spreading centers and subduction zones, which are the other elements of the jigsaw puzzle of the Earth’s plates.
Explain the role of the cell cycle in the production of tissues.
Answer:
the cell cycle allows multicellular organisms to grow and divide a single-celled organism to reproduce
The fundamental function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells. The collection of cells gives rise to the synthesis of tissues.
What do you mean by Cell cycle?Cell cycle may be defined as the entire sequence of events happening from the termination of one nuclear division to the beginning of the next. The cell cycle can be divided into two types. They are as follows:
Interphase.M-phase (Division phase).Apart from this, the Cellular division has three main functions. It may include helping in the reproduction of an entire unicellular organism. Helps in the growth and repair of tissues in multicellular animals. Aids in the formation of gametes (eggs and sperm) for sexual reproduction in multicellular animals.
Therefore, the most fundamental function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.
