Weather is short-term changes in the atmosphere, such as changes in temperature, air pressure, humidity, wind, and precipitation. Climate is the average weather pattern of an area over a long period. •The differences between weather and climate can be summarized as follows: Weather Climate •Weather patterns are caused by the flow of the atmosphere. In the temperate zones, weather conditions usually move from west to east. •The seasons—summer, winter, spring, and fall—are cycles of ...

Basal Metabolic rate energy to maintain life-sustainging activities (i.e. heart rate temperature etc.) for a specific period of time at rest Resting Energy Expenditure amount of energy that an individual needs to consume over a 24 hour period to maintain all of it's internal working activities at rest Kilocalories the unit in which energy is measured Nutrient elements necessary for normal function of body processes Nutrient density the amount of nutrients relative to ...

Tachyphylaxis is a rapid decrease in drug effectiveness with repeated use. An example is the diminished response to nitroglycerin in angina treatment. CCS drugs (cell-cycle specific) Anticancer drugs that are: --> Phase-specific --> Higher selective toxicity. --> More likely to be in-cycle --> Attack only cells that are actively growing and dividing CCNS drugs (cell-cycle non-specific) --> Anticancer drugs that can sterilize tumor cells regardless of whether they are cyc...

A car with speed v and an identical car with speed 2v both travel the same circular section of an unbanked road. If the frictional force required to keep the faster car on the road without skidding is F, then the frictional force required to keep the slower car on the road without skidding is E) F/4 We have an expert-written solution to this problem! A 50.0 N box is at rest on a horizontal surface. The coefficient of static friction between the box and the surface is 0.50, and the coeffic...

What is the process called by which a single fertilized egg develops into a multicellular organism with specialized tissues and organs? Embryogenesis What role does the notochord play in early vertebrate development? It induces the formation of the neural tube by signaling to the overlying ectoderm. How does gastrulation contribute to the development of the three germ layers? Gastrulation reorganizes the blastula into a three-layered structure, forming the ectoderm, mesoderm, and endoderm. ...

DEVELOPMENTAL PSYCHOLOGY QUESTIONS AND ANSWERS FOR A STUDENTS. What is the primary focus of developmental psychology? The study of how people grow and change throughout their lifespan, including physical, cognitive, emotional, and social development. Who is considered the father of developmental psychology? Jean Piaget. What is the main idea behind Piaget’s theory of cognitive development? Children progress through distinct stages of cognitive growth, each characterized by specific abi...

What are the primary reproductive organs in males, and what are their functions? The primary reproductive organs in males are the testes. They produce sperm (spermatogenesis) and secrete male sex hormones, primarily testosterone. Where are the testes located, and why is this location important? The testes are located in the scrotum, outside the abdominal cavity. This location keeps the testes cooler than the rest of the body, which is essential for proper sperm production and maturation. Wha...

CELL BIOLOGY (CELLULAR BIOLOGY OR CYTOLOGY) Cell biology (cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. What is the basic unit of life in all living organisms? The cell. What is the primary function of the cell membrane? To regulate the entry and exit of substances in and out of the cell. What is the role of the nucleus in a eukaryotic cell? It stores genetic material (DNA) and controls cellular activities. What is the ...

COMMON SEXUALLY TRANSMITTED INFECTIONS Q&As 100% What is a sexually transmitted infection (STI)? An STI is an infection passed from one person to another through sexual contact, including vaginal, anal, and oral sex. How are sexually transmitted infections caused? STIs are caused by bacteria, viruses, or parasites, including pathogens like Chlamydia trachomatis, Neisseria gonorrhoeae, and human papillomavirus (HPV). What are common symptoms of sexually transmitted infections? Symptoms may ...

What is the primary driver of global atmospheric circulation? The uneven heating of the Earth’s surface by the Sun. What causes the Coriolis effect to influence wind patterns? The rotation of the Earth. Why do high-pressure systems often bring clear skies? High-pressure systems cause air to sink, preventing cloud formation. What is the difference between weather and climate? Weather refers to short-term atmospheric conditions, while climate describes long-term patterns over a region. H...
