Answer:
Due to average population density.
Explanation:
The population density of Canada is the average population density of the whole Canada whereas the population density of city of Montreal refers to the population density of one city only. There are some regions in the country usually in the rural areas where population density is very low while on the other hand, the population density of cities are very high due to more job opportunities so that's why the population density of Canada is lower as compared to the city of Montreal.

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.

What is biological hierarchy?Biological hierarchy refers to the organization of living organisms into a series of levels, each level being more complex than the one below it. The biological hierarchy begins with the smallest unit of life, which is the cell, and progresses upward to include tissues, organs, organ systems, organisms, populations, communities, ecosystems, and ultimately the biosphere.
Each level of the biological hierarchy is characterized by different properties and interactions. For example, cells are the basic unit of life and perform all the essential functions of an organism. Tissues are groups of cells that work together to perform a specific function, such as muscle tissue, which is responsible for movement. Organs are structures made up of tissues that work together to perform a specific function, such as the heart, which pumps blood throughout the body.

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.

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.

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.
