Calcium-41 has a half-life of 80,000 years. At the end of 240,000 years,
how much Calcium-41 would remain in a sample initially containing 60
micrograms? *
A 7.5 micrograms
B 60 micrograms
C 15 micrograms
D 30 micrograms
If the half-life is 80,000 years, then 240,000 years would be equivalent to three half-lives. In other words, the initial amount of the radioactive calcium-41 would have been reduced in half three times over. Mathematically, this can expressed as
calcium-41 remaining = initial mass of calcium-41 × (0.5)³.
Since we are given the initial mass of calcium-41, the amount of calcium-41 remaining after 240,000 years would be:
60 μg × (0.5)³ = 7.5 μg, or 7.5 micrograms.

Which type of mutation often has the least effect on organisms' traits (and may have no effect at all)? Nondisjunction Substitution Insertion Deletion
Answer:
The correct answer is - substitution.
Explanation:
Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the DNA or RNA of an organism's genome.
In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.

If you assume that the high projection is correct, what is one way the larger
human population can ensure it has enough food?
The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops. Therefore, the correct option is option B.
What is population?The term "population" is frequently used to describe the total number of people living in a particular location. To estimate the number of the residents within a certain territory, governments conduct censuses. The phrase has particular use in the domains of ecology and genetics and is also used to refer to plants, animals, and microbes.
An region with a sexual populace is one in which interbreeding between any two individuals therein is both conceivable and more likely than cross-breeding between individuals from other places. The one way the larger human population can ensure it has enough food is by finding more efficient ways of growing crops.
Therefore, the correct option is option B.

Upwelling currents are caused by:
1.temperature differences between water masses
2.salinity differences between water masses
3.pressure differences between water masses
4.Ekman spiral
Answer:
its the ekman spiral not pressure differences between water masses
Explanation:
Upwelling. Along some coasts, the Ekman spiral causes an upwelling of deeper water to replace the water that has moved offshore. The colder, deeper water is richer in nutrients. These upwelling areas contain some of the richest fishing grounds in the world.

Answer:
D: Electrical energy is transformed to chemical energy.
Explanation:
1. Where and how is energy created in the sun's interior? Starting from
the center, what are the interior layers that this energy travels through?
HELPPP ASAP!!!!!!
The energy within the Sun is generated by the process of nuclear fusion. The layers of the Sun from inward to outward are:
The coreThe radiative zoneThe convection zoneThe Solar's interior:The energy within the Sun is generated by a process called nuclear fusion. During the process, the high temperature and pressure inside the core of the Sun make nuclei separate from their electrons. The fusion of hydrogen nuclei takes place to produce the helium atom.
Radiant energy is discharged during the process of fusion. The energy of the Sun that is generated in the core, moves outwards. First, the energy travels through the radiative zone, in which particles of light, that is, photons carry the energy.
It takes millions of years for the energy to move to the next layer, that is, the convection zone. In this zone, the transferring of energy takes place more briskly. The bubbling effect is witnessed on the Sun's surface and is known as granulation.
Thus, the energy in the Sun's interior is generated by the process of nuclear fusion, and the energy moves from the core to the radiative zone, and eventually to the convection zone.

To make ethanol for use in _______, yeast is provided with sugars that have come from crops such as maize.
Answer: To make ethanol for use in BIOETHANOL( a biofuel), yeast is provided with sugars that have come from crops such as maize.
Explanation:
Ethanol Fermentation is defined as the process whereby sugar( fructose, sucrose or glucose) are broken down by the action of microorganism such as yeast to give of ethanol(alcohol) and carbondioxide as by products.
In the use of ethanol as a biofuel, there are different sources where sugar products can be gotten from, but the main sources of sugar required to produce ethanol come from energy crops. These crops are grown specifically for energy use and include corn, maize and wheat crops.
BIOETHANOL is a renewable source of fuel that can be produced through the yeast fermentation of sugar gotten from crops such as maize. Although ethanol can be used in wine and beer production, sugar sources are usually gotten from grape fruits and barley.

How does particle size affect the porosity of an aquifer?u
Answer:
Porosity is influenced by the differences in sizes of the particles in the rock layer. ... This rock layer has high porosity because smaller particles are not present to fill the empty space between particles. So, there is more open space between particles.

Charles has developed a new advertisement that can be used online. He tests how well it draws people's attention by closely
monitoring the eye movement of 1,000 test subjects as the new ad appears on their computer screens!
Charles finds that 97% of the test subjects' eyes were drawn toward the ad when it appeared. By comparison, only 50% of the test
subjects' eyes were drawn toward a box of plain text when it appeared instead. He concludes that the new ads are better at
attracting people's attention than old ads.
What is wrong with Charles' experiment?
Answer:
He did not compare the new ads to old ads.
