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.

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.

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.

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.

If you are observing worms, ants, and caterpillars, you are studying a biological _________________.
A. community
B. species
C. individual
D. population
E. none of the above
If you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.
What is Biological species?Biological species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
A Community may be defined as a group of individuals belonging to different species living in the same area. A Population may be defined as the number of the same species living in the same area at a particular time.
Here, worms, ants, and caterpillars are organisms of different species with different characteristics such as mode of nutrition, reproduction, and response to the environment.
The biological species are considered as an integral part or component of an ecosystem. The greater the biodiversity in an ecosystem, the greater the stability of the species within that ecosystem.
Therefore, if you are observing worms, ants, and caterpillars, you are studying a biological species. Thus, the correct option is B.

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.
