The right answer is leftover radiation from the big bang.

Cosmic Microwave Background (CMB) is the name given to a very homogeneous electromagnetic radiation observed in all directions of the sky and whose peak emission is located in the field of microwaves (microwaves). . Anticipated in 1948 and discovered by chance in 1964, the CMB allows the scientific community to separate the various cosmological models, in particular by abandoning models based on the perfect cosmological principle and by prioritizing models based on the idea of Big Bang, which predict the emission of such thermal radiation at the time of the primordial Universe.

According to the standard model of cosmology, this fossil radiation was emitted approximately 380,000 years after the Big Bang, when the observable Universe was at the same time much smaller, dense and hot. It was then diluted and cooled by the expansion of the Universe and now has a very low average temperature, of the order of 3 Kelvin (K). The CMB is a very studied physical phenomenon since its discovery for two reasons: it corresponds to the oldest electromagnetic image that it is possible to obtain from the Universe and it presents tiny variations of temperature and intensity according to the observed direction, detailed anisotropies since the beginning of the 1990s which allow gathering a lot of information on the structure, the age and the evolution of the Universe.

Woven bone Select one: a. has its collagen fibers randomly oriented. b. has a porous appearance. c. is organized into thin sheet

kogti [31]

Answer: A . Has its collagen fibers randomly orientated.

Explanation:

In the microscopic anatomy of the bone, an osteon (basic microscope unit of the bone) can be arranged into two categories; woven bone or lamellar bone.

As the name suggests woven bone is characterized by the random orientation of the collagen fibers . These collagen fibers haphazardly form to give the visual appearance of an intertwined (woven) network of collagen fibers.

Due to the randomness of the collagen fibers orientation woven bone is thus mechanically weaker than lamellar bone. Woven bone is formed/produced when osteoblasts produce osteoids rapidly within the bone matrix thus woven bone has the ability to form quickly as needed.

Woven bone is thus immature bone or pathologic bone with no stress orientation, it has a high percentage of osteocytes per unit volume and a high rate of turnover.

Having blood glucose levels that are too high or too low is very dangerous. Having a blood glucose level that is too high results in high blood pressure. Having a low blood glucose level causes hypoglycemia. Hypoglycemia causes symptoms like dizziness, fatigue, exessive sweating, and shaking.

A good way for an adolescent to build and protect her bones is to:

muminat

The best way for adolescent to build and protect his or her bones is to ingest food products that are rich in calcium for it is known to make bones stronger. Another way is to be able to do exercise as a daily routine so that the bones are exercised every day to prevent bone disease, this will stenghten the bones and make them more stronger.
