Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

Why do you think it's important for scientists to study plate tectonics? Explain.
Studying plate tectonics is important because it helps explain Earth's surface features, predict natural disasters, investigate Earth's history, explore natural resources, and understand global climate patterns. It is a multidisciplinary field that provides valuable insights into the dynamic nature of our planet.
Scientists study plate tectonics for several important reasons. Firstly, understanding plate tectonics helps scientists explain the formation of different features on Earth's surface, such as mountains, valleys, and ocean basins. By studying the movement and interactions of Earth's tectonic plates, scientists can better understand the processes that shape our planet.
Secondly, studying plate tectonics is crucial for predicting and understanding natural disasters. Earthquakes, volcanic eruptions, and tsunamis are all related to tectonic activity. By analyzing plate boundaries and identifying areas prone to seismic activity, scientists can provide early warnings and help communities prepare for potential disasters.
Furthermore, studying plate tectonics is essential for investigating Earth's history. The movement of tectonic plates over millions of years has shaped the continents and influenced the evolution of life on our planet. By examining the distribution of fossils and rock formations, scientists can reconstruct past tectonic events and gain insights into Earth's geological history.
Additionally, understanding plate tectonics is crucial for exploring natural resources. Many valuable minerals and energy resources are formed as a result of tectonic processes. By studying plate boundaries and their associated geological features, scientists can identify potential locations for mining and resource extraction.
Lastly, studying plate tectonics contributes to our understanding of global climate patterns. The movement of tectonic plates affects ocean currents, weather patterns, and the distribution of landmasses. By analyzing these interactions, scientists can better predict and understand climate change.

What are the main characteristic for changing an organism?The kingdom is a smaller taxon than the recently added domain, which is a more expansive taxon. Similarities in outward physical characteristics serve as the foundation for the Linnaeus system.
Gene variants, sometimes known as mutations, can cause genetic differences, or a normal process in which genetic information is rearranged as a cell prepares to divide can also cause genetic variations (known as genetic recombination).
Therefore, Different phenotypes can be introduced into an organism by genetic changes that change gene activity or protein function.

Identify the different organelles found in different cells and list the organelles and structures the characterize each of them.
Answer: Organelle is a sub-unit of cell and it is involved in performing specialized function within the cell. The type of organelles vary from organisms to organisms.
Explanation:
1. Centrioles are the cell organelles in which the spindle fibers are organized to which the chromosomes attach and mitotic division takes place. These are present only in animals and they are absent in plant and fungal cells.
2. Vacuoles are the storage organelles which store excess water, waste metabolites, sugars and other components in them. In plant cells they are of larger size whereas the vacuoles are small in size in case of the animal and fungal cells.
3. The plants cells and fungal cells have cell wall made up of cellulose (plants) and chitin (fungus) respectively. The cell wall is absent in animal cells.
4. The plant cells and fungal cells do not possess cilia and flagella for locomotion whereas animal cells have cilia and flagella.

Specialisation in the knowledge society and its need
Posted by Bernardo Lajus on Mon, 01/07/2013 - 11:54.
Contemporary society is characterized by globalization. The information and the speed with which they reach society amaze anyone who has experienced the 1980s and 1990s. Because of the technology and facilities it brings, the recipients of this information become increasingly demanding, in every way. Demanding with you, with others, with things, with everything, making the world so demanding, to the point that services and information are insufficient, exhausting, poor.
Because of this, the world specializes. The professions have gained new directions, new perspectives. The courses that were previously generic, such as engineering, law, medicine, became insufficient and were gaining tributaries. If before the general practitioners of mechanical engineering and law realized the professional demand, over the years and the evolution of society, it required professionals to become specialists, creating branches and opening possibilities.
Today, specialists, masters and doctors are essential for the rapid development of society, required everywhere. Despite the harm spawned (such as time demanded, or "knowing much about little), specialization in the knowledge society brings inegulable benefits. The creation of new jobs, the deepening of knowledge and the quality of services makes society evolve even more.
Thus, although the human being, in his individuality, is not expanding his way of knowing, but rather reducing himself to specificity, society as a whole plunges into a profound expansion of knowledge, bringing this to everyday life, from the most trivial to the most complex of works, specialization is necessary and beneficial.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer,
75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant
over brown (w). During the summerthe field where they live experiences a drought. The
summer drought lasts for two years, through
many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the
drought?
O A. The rabbit population will consist of 0% white rabbits and 100% brown rabbits.
OB. The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
C. The rabbit population will consist of 95% white rabbits and 5% brown rabbits.
D. The rabbit population will consist of 80% white rabbits and 20% brown rabbits.
Answer:B
Explanation:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits. Therefore, option B is correct.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
The rabbit population will consist of 35% white rabbits and 65% brown rabbits. Therefore, option B is correct.
