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.

Solid liquid separation of microbial product in industry using filtration and centrifugation techniques?
Answer:
Filtration.
Explanation:
Filtration can be used to separate solid part from liquid part of microbial product because it is less time consuming. This filtration process can easily separate liquids from solid material by allowing liquids to pass through the small holes and collecting solid on the surface of sieve. centrifugation techniques are used to separate liquids of different densities so it can't separate solid from liquid, it can only be done by filtration process.

Do mutations always lead to evolution?
Yes, because mutations create adaptations that give a competitive advantage.
No, because most mutations lead to death of the organism.
No, because some mutations happen in the body cells, so they are not passed on.
Yes, because there would be no change in populations without mutations.
Answer:
Yes, because mutations create adaptations that give a competitive advantage.

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.

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.

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.
