A teacher sprinkles some iron shaving on a clear tray. She places two magnets in the shaving with the north ends facing each other. Based on the cause and effect relationship between the magnets, which phenomenon is the teacher modeling for her students?

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:

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.

The energy within the Sun is generated by the process of nuclear fusion. The layers of the Sun from inward to outward are:

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.

Answer:

The Reproductive System

Explanation:

In living things, the reproductive system is responsible for producing children. It is a group of hormones, tissues and organs that cooperate to promote the conception and development of new ones.

Men have a variety of reproductive organs, including the testes, epididymis, vas deferens, prostate, etc. Sperm production and distribution are facilitated by these structures. In women, the reproductive system includes the uterus, fallopian tubes, cervix, and vagina, among other structures.

These organs play an important role in the development of the egg during pregnancy, fertilization, implantation of the fertilized egg, and the growth and development of the fetus. Additionally, the reproductive system contains hormones that control reproduction, such as testosterone in males and estrogen and progesterone in females.

Scientists must collect accurate information that allows them to make evolutionary connections among organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.

Explanation:

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.

Explanation:

Answer:

uwuExplanation:

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.
