Most articles pass right through the atom, this means that most of the atom is an empty space.

An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.

Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.

As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

Today's societies are immersed in a world of telecommunications, where most information reaches them through television, mobile devices, and computers, the latter two through the Internet or cellular data. Therefore, one way to make people aware of the three main factors of the ecological footprint caused by humans, namely transportation, housing, and food decisions, is through government educational programs and educational advertisements through telecommunications technologies, that explain the impact of state and inhabitants of each of these state decisions regarding transportation, housing, and food.

These programs must contain topics related to how fossil fuels affect ecosystems through greenhouse gases, how housing construction and the raw material for building construction affect natural habitats by displacing endemic species from their habitat natural, and also how agriculture or intensive fishing damages each of the ecosystems in almost irreversible ways.

We can conclude that the correct answer is:

Answer: Diffusion is the spread of particles from where they are more concentrated to where they are less concentrated

Explanation: When particles(solute) move from their higher concentration to their lower concentration it is called diffusion.

Diffusion is a passive process hence it does not require energy. It only requires a concentration gradient of particles to be present as it occurs along the concentration gradient.

diffusion stabilizes the number, movement & energy of solution on all sides.

The main cause of the seasons is this. The Northern Hemisphere has warm weather when the Earth is tilted toward the sun, and cool weather when the Earth is tilted away from the sun. Thus, option A is correct.

The Earth's axis is currently inclined 23.5 degrees. The Earth rotates on its axis at a fixed tilt as it orbits the Sun. The Northern and Southern Hemispheres are tilted away from the Sun.

At different times of the year as a result of this angle. A hemisphere experiences winter and longer nights as it is tilted away from the Sun.

Therefore, there would be no seasonal cycle If Earth was not tilted.

Scientists have concluded that the magmatic system of Mount St. Helens has evolved from a relatively simple to a more complicated state as the volcano matured based on a thorough chemical examination of the eruptive products from each stage of volcanism.

According to the data, interaction between more mafic (basalt to andesite) and more silicic (dacite) magma batches increased from the earliest to most recent stages of Mount St. Helens volcanism. The volcano's initial eruptive phase mostly comprised of a cluster of domes encircled by an apron of tephra and debris fans of broken volcanic materials. Large portions of a center cluster of dacite domes and surrounding fans were buried by these lava flows, which sparked the cone-building process.

Answer:

the gene for yellow body and the gene for forked bristles

Explanation:

The two genes that will have the highest recombination frequency are the gene for yellow body and the gene for forked bristles.

Gene recombination refers to the exchange of genetic materials between different gene-containing regions (loci) on the same chromosome or between two or more independent chromosomes. A linkage map shows the frequency of recombination between genes.

Generally, on a linkage map, when two loci are close to one another on the same chromosome, the frequency of recombination of the genes would be less than that of two loci that are further apart. In other words, the closer the loci, the lower the frequency of gene recombination and vice versa.

In this case, the distance between the genes for yellow body and tan body is 27.5 map units, yellow body and sable body is 43 map units, yellow body and forked bristles is 56.7 map units. The genes for yellow and forked bristles are the furthest to each other with 66.7 map units and, as such, will have the highest recombination frequency.

Explanation:

If the amount of carbon-14 in the original sample had been 48 grams, 6 gm carbon-14 would have been left after 17,100 years

The amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.

The half-life (t½) of C-14 is 5700 years, which means that after 5700 years half of the sample would have decayed and half would be left as it is.

\(\frac{48}{2} = 24\) mg decays and 24 g remains left.

\(\frac{24}{2} = 12\) mg decays and 12 g remains left.

\(\frac{12}{2} = 6\) mg decays and 6 g remains left.

Thus, after three half-lives or 17100 years, 6 g of C-14 will be left.
