Tissue cultures (samples of cancer cells) are taken from cancer patients, and the cells are then grown in a laboratory. What is the purpose of growing cancer cells in a laboratory?
The purpose of growing cancer cells in a laboratory is to test medicinal treatments before giving them to patients.
Cancer cells are cells that grow and divide at a rapid and unregulated pace. Although cancer cells are regularly created in the body, the disease known as cancer only occurs when immune cells (particularly natural killer cells) fail to recognize and/or destroy them.
The correct answer between all the choices given is the first choice or letter A. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
The answer is to test medicinal treatments before giving them to patients .

Explanation:
list the organelles found in plant cells, in amoeba, and common to both.
Answer:
Amoeba are unicellular eukaryotes found in aquatic environments. The organelle that is found in amoeba are nucleus, contractile vacuole and food vacuole and organelle found in plant cells are nucleus, endoplasmic reticulum, Golgi apparatus, vacuole, chloroplast, mitochondria, peroxisomes.
The organelles that are common in amoeba and plant cells are nucleus and vacuole. Both plant and amoeba have a membrane-bound nucleus in which their genetic material is packed.
The role of the vacuole in plant cell and amoeba is that it maintains the proper osmotic pressure in the cell and prevent cell from bursting. It also helps in the collection of waste material and its disposal.
Major factors that determine a population's growth rate
Final answer:
The population growth rate is influenced by birth rates, death rates, immigration, and emigration. The equation to calculate growth rate is growth rate = birth rate – death rate. Economic growth is also related to population growth, as labor demands affect GDP and standards of living.
Explanation:
Major Factors Determining Population Growth Rate
The growth rate of a population is primarily determined by four key factors: birth rates, death rates, immigration, and emigration. If the birth rate exceeds the death rate, the population increases. Conversely, if the death rate is higher than the birth rate, the population size will start to decline. When birth and death rates are equal, the population size remains constant. Additionally, populations gain individuals through immigration and lose individuals through emigration.
Furthermore, population growth can be calculated using a simple formula: growth rate = birth rate – death rate. This equation highlights the importance of fertility rates, life expectancy, and net immigration levels, which are also considered by demographers when studying population characteristics. Populations do not always grow continually; growth depends on various factors, including the average age of individuals within the population, local economic conditions, and availability of resources such as food, moisture, and oxygen.
When discussing population growth and economic growth, the labor market and population size are crucial since they influence the Gross Domestic Product (GDP) and, consequently, the standard of living. As the economy grows, more labor or increased labor productivity is necessary to meet consumer demands. Countries with smaller, well-managed populations often enjoy higher standards of living than overpopulated ones. Thus, population growth rates have a direct impact on economies locally and globally.
1) Which of the following brain regions is indicated by the arrow?
A. Amygdala
B. Hypothalamus
C. Hippocampus
D. Pons
2) What is the primary function of the brain region indicated by the arrow?
A. Memory formation
B. Sleeping, waking and dreaming
C. Problem solving
D. Regulation of body temperature
E. Emotional response
The pons is a mass of nerve fibers located at the base of the brain in an area known as the brainstem. It is the largest part of the brainstem and connects the two halves of the cerebellum.
The brain region indicated in the figure is the PONS (Option D).The pons is located below the midbrain and above the medulla oblongata (i.e., the medulla).The main functions of the pons include sleeping, waking and dreaming (Option B).The pons plays a fundamental role during rapid eye movement sleep (REM), which is a unique phase of sleep characterized by the random rapid movement of the eyes.The pons regulates the functions carried out by the cranial nerves and carries information related to motor function, including walking.In conclusion, the brain region indicated in the Figure is the pons, whereas the main functions of the pons include sleeping, waking and dreaming.

The _____ law of thermodynamics states that energy can't be created or destroyed. Two natural sources of energy on Earth are the _____.
A. first, Sun and core of Earth
B. second, Sun and rock
C. second, Sun and biosphere
D. third, core of Earth and hydrosphere
Answer:
Option A, first, Sun and core of Earth
Explanation:
According to first law of thermodynamics,
An energy can never be created nor destroyed, it can only be converted from one form to other and therefore the first law of thermodynamics is known as law of conservation of energy.
There are only few energy sources for planet earth – Solar energy, gravity, rotation of earth and radioactive energy
Solar energy is the prominent source of energy that drives several natural process like winds, hydrologic cycle, biosphere ecological cycle , and also derives the overall climate system . While the earth core causes gravitational force which is very essential for several natural process like rotation, tides, etc.
