Anthropologists occasionally apply their work to real-world problems but most of the time they conduct academic research directed at their academic peers. True or false?.
The correct answer for this question is True.
The term "anthropology" literally means "the science of humanity." Many disciplines, from anatomists to historians to psychologists, could claim the same lofty title. However, there is something about the anthropological study of "everything human" that distinguishes anthropologists and, in my opinion, gives us the primary right to the phrase "we study people."
Applied anthropology is the application of the discipline to address academic research and facilitate change. This is also known as anthropological practice. Academic peers, on the other hand, is primarily concerned with teaching the subject of anthropology and contributing to the field's overall knowledge base.

Frank wants to determine how the type of container, that holds a liquid, affects the evaporation rate of the liquid. Which of the following describes the best type of scientific investigation for finding the answer to this question?
Group of answer choices
An experiment in which the shape the container is made of is changed, but all other variables are kept the same.
An experiment that varies the temperature of the liquid, but keeps all other variables the same.
Observations of how long it takes rainwater, that forms puddles in various outdoor locations, to evaporate.
Observations in which measurements are taken of the water level in the same cup after evaporation has occurred.
An experiment in which the shape the container is made of is changed, but all other variables are kept the same is best type of scientific investigation for finding evaporation rate.
It is implied by the term "surface phenomena" that evaporation only takes place at the liquid's surface. In order to separate from the liquid and enter the atmosphere as a gas during evaporation, the liquid's surface-located molecules must overcome the forces of attraction between molecules.
The impact of evaporative cooling on permeable pavements depends in large part on the evaporation rate. It is influenced by an intricate web of variables, including size, structure, moisture content, air void content, relative humidity, water temperature, and temperature of the air.
The best kind of scientific experiment for determining evaporation rate is one in which the material the container is constructed of is changed but all other factors are left constant.

In the front of the thigh, there is a collection of muscles known as the quadriceps femoris. The vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris are the four distinct muscles that make up the quadriceps, which in Latin means "four headed."
The femur bone serves as the origin of each vastus muscle, which attaches to the patella, or kneecap. The rectus femoris, which also connects to the kneecap, partially encloses the three vastus muscles. The rectus femoris, in contrast to the vastus muscles, enters into the hip bone.

Synthesizing cell walls with mycolic acids requires a great deal of energy. do you expect acid-fast bacteria to grow fast or slow compared to other bacteria?
They move much more slowly because producing this layer requires a lot of energy, which diverts energy from growth and reproduction.
Mycolic acid synthesis is what?Major and distinct long-chain fatty acids known as mycolic acids are crucial parts of the cell membrane of Mycobacterium TB. They are essential components of mycobacterial pathogenicity and play a critical role in the architecture and impermeability of the cell wall, which contribute to the organisms' inherent resistance to the majority of antibiotics. The eukaryotic-like multifunctional enzyme FAS I and the acyl carrier protein (ACP)-dependent FAS II systems, which are made up of a number of distinct mono-functional proteins and each catalyze one reaction in the route, are needed for the biosynthesis of mycolic acid precursors. The mycobacterial FAS II synthase is unable to produce new medium-chain fatty acids from acetyl-coenzyme A, in contrast to other bacteria's FAS II synthases. Instead, it elongates medium-chain fatty acids that had already been produced by FAS I to form meromycolic acids.Learn more about the mycolic acid with the help of the given link:

Subject is environmental science
The unit used in a pyramid of number is (d) individuals.
Pyramid of number is a type of graphical representation that shows how many number of organisms are present in each trophic level. This pyramid cannot have a constant shape as the the population of each species belonging to a specific trophic level changes from one ecosystem to another. Hence the pyramid can be of three types bases on shape: upright, inverted or partly upright.
Individual is one single organism of any species. Since the pyramid of number counts the total number of organisms in each trophic level, therefore individual is the correct unit for it.

Which tree species are shade-tolerant and considered competitors in their respective ecosystems?
From northern to southern geographic regions, trees have different tolerances for shade, such as sugar maple and ash in the eastern United States.
When young, most maples, oaks, and eastern white pines can tolerate greater shade, but as they get older, they become less tolerant.
Shade toleranceShade tolerance refers to a tree species' capacity to establish itself, develop, and survive in conditions of low light intensity, duration, and quality. When there is little light available, tolerant plants can thrive relatively well. Intolerant species cannot thrive in low light conditions, but thrive in conditions that are nearly as bright as full sunshine. Other species are more adaptable and are viewed as being more intermediate between environments with greater shade and full sunlight. Tolerant trees proliferate in forests and create understories beneath the canopies of more tolerant trees or even in their own shadow. Only in the open or in areas with significant canopy gaps can intolerant trees effectively propagate.Hence, sugar maple and ash are two examples of shade tolerant species.

What do host cells do?A live cell that houses and provides sustenance for an alien creature is called a host cell. Two organisms are considered to be in a symbiotic relationship when they coexist and have a tight, sustained biological interaction.

Instead of its regular output, an infected cell generates more viral protein and genetic material. an organism or cell that has contracted a virus or another kind of microbe. A virus is a tiny, contagious particle that can only multiply when it infects a host cell. In essence, viruses reprogram the host cell to become a virus factory as they "commandeer" it and use its resources to produce other viruses.

A measure of the ability of a drug, once bound to the receptor, to produce a measurable physiologic effect is know as: intrinsic activity.
A drug's physiologic processes are affected by two factors, which are affinity and intrinsic activity:
A drug's affinity is a measurement of how tightly it binds to a receptor.The ability of a medication to produce an impact activating stimuli and alter cellular activity after binding to a receptor is measured by its intrinsic activity.Drugs can differ in their affinity and intrinsic activity. Agonists have intrinsic activity, which is the capacity to have a measurable impact, as well as affinity, which is the capacity to bind to the receptor.
