How would you calculate density for a cubic solid ?

Biology

You are given the mass of the metal block, but you must calculate its volume using the measurements of the given dimensions. For a rectangular solid, volume = length x width x height; therefore, the volume of the block is (3 cm)(5 cm)(4 cm) or 60 cubic centimeters. The density is 14 g/60 cc or 0.23 g/cc.

First find the volume. The expression for regular shape like cubic solid is v=length x width x height
Then find the mass of the cube by using a scale. Finally use the expression to find the density.
D= mass divided by volume (D= mass/volume )

When you listen to your favorite music, what is the order in which the sound approaches and enters your nervous system and is in
kvasek [131]
In the ear, the sound waves enter through the auditory canal and hit the eardrum (tympanic membrane). The eardrum amplifies the sound and the waves move on to the middle ear, where three bones called the ossicles (malleus, incus, and stapes) amplify the sound further and vibrate. Then, the sound waves go to the cochlea where tiny hairs and other receptors turn the sound waves into a nerve impulse. This impulse is sent to the brain via the auditory nerve and interpreted by the brain.

If genetic drift is occurring you will be able to predict which allele will become more prevalent.
Blizzard [7]

Answer:

b. False

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. As happens at random, it is impossible to predict which allele will be prevalent in a population suffering from genetic drift.

Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent.

Thus limiting the genetic content of a particular group, restricted to the prevailing individuals. It is up to them, integration into another population, if an adaptation is maintained, or over time, from geographic and later reproductive isolation, constitution of a new species (principle of the founding species).

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals.

During evolution, a hypothesis concerning the decimation of dinosaurs, which occurred around 66 million years ago, establishes not only the end of these animals, but of various life forms (including plants), due to a huge asteroid that would have reached planet, raising a dense cloud of dust resulting from the collision, compromising photosynthetic processes (dependent on solar energy), as well as the respiration and nutrition of organisms.
