Dimensions of Health and Illness01:21

Dimensions of Health and Illness

9.1K
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Brick Sizes01:21

Brick Sizes

181
Brick sizing plays a crucial role in construction, influencing both the aesthetics and structural integrity of buildings. Bricks are defined by three dimensions: width, thickness, and length. They are commonly designed to fit modular measurements, typically in multiples of 4 inches or 8 inches in width, to facilitate uniform construction and compatibility with other building materials.
Modular bricks are the most common type and are sized to include the mortar joint, which is essential for...

Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.9K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Estimation of the Physical Quantities01:05

Estimation of the Physical Quantities

6.6K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

Cell Size01:22

Cell Size

122.0K
Cell sizes vary widely among and within organisms. Bacterial cells range between 1-10 micrometers (μm)and are considerably smaller than most eukaryotic cells. The smallest bacteria are 0.1 μm in diameter—about a thousand times smaller than eukaryotic cells, which typically range from 10-100 μm.
Surface Area
Cells can take in nutrients and water via diffusion through the plasma membrane itself or through specific channels in the membrane. The area of the membrane surrounding...

Gene-Environment Interactions01:20

Gene-Environment Interactions

758
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

Area of Science:

  • Comparative biology
  • Developmental biology
  • Physiology

Background:

  • Organism size spans over twenty orders of magnitude.
  • Individual size within species is influenced by environmental conditions.

Purpose of the Study:

  • To identify conserved laws and mechanisms governing organism size.
  • To explore the relevance of size regulation to fundamental biological processes and medical conditions.

Main Methods:

  • Comparative analysis of growth patterns across diverse species (e.g., drosophila, salamander, mouse).
  • Investigation of environmental influences on individual size variation.

Main Results:

  • Emergence of universal laws and conserved mechanisms related to organism growth.
  • Identification of shared principles underlying size control in different organisms.

Conclusions:

  • Understanding organism size regulation provides insights into fundamental growth processes.
