how can homeostasis be studied indirectly?

Franz Uri Boas (July 9, 1858 – December 21, 1942) was a German-born American anthropologist and a pioneer of modern anthropology who has been called the “Father of American Anthropology”.

How does the bone remodel itself?

The remodeling cycle consists of three consecutive phases: resorption, during which osteoclasts digest old bone; reversal, when mononuclear cells appear on the bone surface; and formation, when osteoblasts lay down new bone until the resorbed bone is completely replaced.

Why doesn’t the periosteum cover the articular cartilage?

The periosteum doesn’t cover the portion of bones that contains articular cartilage, which is the cartilage found in joints that keeps the bones from rubbing together. … It is not as tightly packed and contains cells that help in bone growth and repair.

Where within the epiphyseal plate are the dividing cartilage cells located?

Near the outer end of each epiphyseal plate is the active zone dividing the cartilage cells.

What forms Embryonically from?

Embryonic/fetal development proceeds from rostral (nose and mouth area) to caudal (posterior). The skull and vertebral column are produced by intramembranous ossification. As development proceeds down the body axis, the long bones of the arms and legs are produced by endochondral ossification.

What is epiphyseal fusion?

Epiphyseal fusion in primates is a process that occurs in a regular sequence spanning a period of years and thus provides biological anthropologists with a useful marker of maturity that can be used to assess age and stage of development.

What are the inactive bone cells that help to maintain the ECM?

Relatively inactive bone cells that help to maintain the ECM are: osteoblasts.

What is a cline in anthropology quizlet?

Terms in this set (29)

Cline is a gradual change in characteristics from one population to another. Specific traits following a geographical continuum are called a cline. No races only clines.

What is Wolff’s law quizlet?

Wolff’s law. States that bone in a healthy person or animal will adapt to the loads under which it is placed. Hormonal controls. determine whether and when remodeling occurs in response to changing blood calcium levels, but mechanical stress determines where it occurs. You just studied 11 terms!

Why do microsatellites mark a key discovery in DNA research?

Why do microsatellites mark a key discovery in DNA research? … They are highly individualized repetitive stretches of nuclear DNA. In his work on pea plants, Mendel found that plant height was inherited independently of the type. or color of the seed coat.

What did scientists learn by studying the pelvis of Ardipithecus?

The pelvis, reconstructed from a crushed specimen, is said to show adaptations that combine tree-climbing and bipedal activity. The discoverers argue that the ‘Ardi’ skeleton reflects a human-African ape common ancestor that was not chimpanzee-like.

What did the discovery of Ardi suggest about the kind of habitat in which Bipedality evolved?

What evidence suggests that Ardi could climb well? that bipedality evolved in a grassland environment, but fossil evidence suggests that it evolved while our ancient ancestors were living in a woodland habitat and still spending time in trees.

How do scientists know how old the Ardi fossil is?

How do scientists know how old the Ardi fossil is? The Ardi fossil was found in sediment that was sandwiched between volcanic deposits that dated to 4.4 million years ago. You just studied 7 terms!

In what geographical region would you expect to find lemurs in natural habitats?

Lemurs are primates found only on the African island of Madagascar and some tiny neighboring islands. Because of its geographic isolation, Madagascar is home to many amazing animals found nowhere else on Earth.

In which of the following primate groups would you expect to find a y 5 molar pattern?

In addition, the lower molar teeth of apes and humans have five cusps, or raised points, on their grinding surfaces. This is known as a Y-5 pattern because the area between the cusps roughly is in the shape of the letter Y. Monkeys only have four cusps on their lower molars.

Where did the first Platyrrhine primates to reach South America most likely migrate from?

Monkeys originated in Africa and the first group known to have reached South America are thought to have migrated there up to 40 million years ago, when the land masses were probably between 1500 and 2000 kilometres apart, around a quarter of the distance now.

Which characteristic of life is associated with homeostasis?

They keep things relatively stable on the inside regardless of the conditions around them. The process of maintaining a stable internal environment is called homeostasis. Human beings, for example, maintain a stable internal body temperature.

How can organisms control and respond to the changes in the environment for survival?

The control systems that allow organisms to respond to changes are incredibly important. Cells called receptors , which detect stimuli (changes in the environment). The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the body.

What are the adaptations that contribute to the diversity of mammals and enable them to live in a variety of habitats?

Species of mammals have developed varying adaptations in response to the different environments in which they live. Mammals in cold climates have insulating layers—a thick coat of fur, or a thick layer of fat (blubber)—that help retain body heat and keep the animal’s body temperature constant.
