Answer:

There are 1600 atoms when organism just died.

Explanation:

The statement is incorrect. The correct statement is:

If a sample known to be about 11,460 years old and has 400 carbon 14 atoms. How many atoms are in the sample when organisms just died?

The amount of atoms associated with radioactive isotopes decreases exponentially in time by means of the following formula:

[tex]n(t) = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)

Where:

[tex]n_{o}[/tex] - Initial amount of atoms.

[tex]n(t)[/tex] - Current amount of atoms.

[tex]t[/tex] - Time, measured in years.

[tex]\tau[/tex] - Time constant, measured in years.

In addition, the time constant can be calculated in terms of the half-life of the radioactive isotope ([tex]t_{1/2}[/tex]), measured in years:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)

If we know that [tex]t_{1/2} = 5,730\,yr[/tex], [tex]t = 11,460\,yr[/tex] and [tex]n(11,460\,yr) = 400[/tex], then the initial amount of atoms is:

[tex]n_{o} = \frac{n(t)}{e^{-\frac{t}{\tau} }}[/tex]

[tex]\tau = \frac{5,730\,yr}{\ln 2}[/tex]

[tex]\tau \approx 8,266.643\,yr[/tex]

[tex]n_{o} = \frac{400}{e^{-\frac{11,460\,yr}{8,266.643\,yr} }}[/tex]

[tex]n_{o} \approx 1600[/tex]

There are 1600 atoms when organism just died.

Explanation:

It drops from 9 to 3 individuals to the female population between the ages of 9 and 19.

A population is made up of every organism of a specific species that resides in a specific location. Demography is the statistical study of populations and how they evolve through time.

Population size, or the total number of people, and population density, or the number of people per unit of space or volume, are two crucial indicators of a population. Ecologists use quadrats and the mark-recapture technique to evaluate the size and density of populations.

A population of organisms may be dispersed randomly, uniformly, or clumped. When a population is described as uniform, it is evenly spaced, random indicates uneven spacing, and clumped, it is dispersed in groups.

Therefore, It drops from 9 to 3 individuals to the female population between the ages of 9 and 19.

The most common explanation of the transmission of the Black Death is flea bites. Infected fleas were carried on rodents, and these fleas transmitted the virus to humans.

There are still several different theories about how the Black Death was spread, however. There's a Wiki page called "Theories of the Black Death" that may be helpful.

At the time of the Black Death, bacteria and viruses hadn't been discovered yet. People thought that sickness was transferred through bad smells, which were called "miasma."

The long beaks of the masks were stuffed with strong-smelling herbs, spices, and dried flowers—lavender, roses, peppermint—which were thought to keep away the "evil" smells that were thought to cause disease.

Pretty cool stuff!

Cheetahs have been through a genetic bottleneck; evidence for this is that there is very little genetic variability (Option c).

A genetic bottleneck is a natural process where a population and/or species lost part of this genetic diversity.

Explanation:

Since oceans cover 71% of the Earth’s surface, understanding what the seafloor looks like, and where different processes, such as ocean currents are active, is hugely important. Mapping the seafloor helps to work out things like where different types of fish live, where resources may be, such as rare metals and fossil fuels, and whether there is a risk of underwater landslides happening that might cause a tsunami. Mapping the seafloor is very challenging, because some cannot use the same techniques that some would use on land. To map the deep ocean, there's a tool used called a multibeam echo-sounder, which is attached to a ship or a submarine vessel.

A-They are stored as fat.

Explanation:

In animals, the excess of carbohydrates or glucose is first converted into glycogen (polysaccharide) through the process called glycogenesis. ... When glycogen reservoirs are saturated, excess carbohydrates, as well as proteins, are converted into fats which are then majorly stored in adipose tissues.

What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?

Answer;

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.

Explanation;

-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.

Answer:

Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.

Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.

Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.

Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.

Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.

Therefore, organ and organelles differ in their functioning.
