Answer:

Bone strength is influenced by changes in the structure (size and shape) and composition [cortical (compact) bone, trabecular (sponge-like) bone, amount of cartilage] of the bone. 6 A high peak mass at a young age and the decrease of bone loss at a later age are two ways to reduce osteoporosis risk.

How does the process of natural selection work?
Vedmedyk [2.9K]

Answer:

If I am correct it is when the weaker individuals or mutated individuals are killed of by other predators or by nature. Because they cannot survive this is natural selection because they are killed of by nature. Then if they are weak their species will go extinct, thus they are naturally selected to die and only the strong species remain.

Group the following into the appropriate range of measurement.
Vesna [10]

Answer:

Hydrogen atom & glucose molecule --- atomic.

Herpesvirus, DNA --- ultramicroscopic.

Protozoan, Rickettsia - microscopic.

Roundworm and algae --- macroscopic

Explanation:

1) Hydrogen atom & glucose molecule --- atomic.

The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.

2) Herpesvirus, DNA --- ultramicroscopic.

Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.

3) Protozoan, Rickettsia - microscopic.

Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is ( 10^3  \ \ to  \ \ 10^{10}), which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).

4) Roundworm and algae --- macroscopic

Naked eyes can see macroscopic organisms; for example, several types of circular worms and algae can be seen by them.

Estimating the Age of a Rock Layer
Ganezh [65]

Answer:

Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.

Explanation:

Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
