Benny uses a compass to navigate his way through the woods when he
is carnping. The needle on the compass reacts to Earth's magnetic field
by always pointing north. Which part of Earth is responsible for creating
its magnetic field?
A. Cilist
B. inner core
C. mantle
D. outer core

Answers

Answer 1

Answer

Outer Core

Because of the weight of the melting moving metal creates energy

Answer 2

Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.

What role of outer core of earth in magnetic field?

Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.

The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.

The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.

Therefore, Because of the weight of the melting, moving metal creates energy.

expounded by Charles Darwin and is now believed to be the main process that brings about evolution

True
False

Answers

True

The process is called natural selection and was first explored by Charles Darwin in the 19th century.

NATURAL SELECTION is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. This concept was first developed by Darwin (both statements are TRUE).

Darwin referred to evolution as the process of 'descent with modification'.

The main mechanism by which organisms evolve to adapt to their environments is natural selection.

The theory of evolution by natural selection was developed by Darwin and it is now widely accepted as the main cause of evolution.

According to Darwin, species change (evolve) over time, thereby giving rise to new species that share a common ancestor.

In conclusion, NATURAL SELECTION is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of evolution by natural selection was first developed by Darwin (both statements are TRUE).

Santos and Lüderitz are the same distance from the equator, and both cities are near the ocean. The air temperature in Lüderitz is colder than the air temperature in Santos. What causes the air temperature in these places to be different? Explain what causes the difference as completely as you can.

Answers

Answer:

The Ocean Currents.

Explanation:

if you look at a current map, you'll see warm currents near Sanots and cold ones near Lüderitz. Therefore, the air in Sanots is a lot warmer and the air in Lüderitz is colder.

The phenomenon of the ocean current is responsible for this deviation of air temperature between two places.

What do you mean by Air temperature?

Air temperature may be defined as the temperature of the surrounding air of organisms including humans.

The ocean water captures the heat from the sunlight and increases the temperature of the ocean. This heat is then entranced through ocean circulation and increases the temperature of the air as well as the atmosphere.

The air temperature in Luderitz is colder because the ocean of this region receives less sunlight in low intensity which results in less heat captured by the ocean and makes the air a little bit colder than that of Santos oceans.

Therefore, it is well described above.

In a DNA molecule, the number of adenine bases equals the number
of thymine bases because thymine on one strand bonds to adenine
on the other strand.
True or false

Answers

The answer to the problem is true

It is TRUE that in a DNA molecule, the number of adenine bases equals the number of thymine bases because thymine on one strand bonds to adenine on the other strand.

DNA COMPOSITION:

DNA is composed of nucleotides subunits. There are four nucleotides present in the DNA molecule namely: Adenine, Cytosine, Guanine and Thymine.

Adenine and Thymine hydrogen bond together while Cytosine and Guanine hydrogen bond together i.e. A-T, G-C.

According to Chargaff rule, the amount of adenine bases equals the amount of thymine bases while the amount of guanine bases equals the amount of cytosine bases.

This is because adenine on one strand of DNA bonds to thymine on the other strand of DNA, hence, they must be in the same amount.

How does natural selection lead to the evolution of a species?

Answers

Answer:

One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

Explanation:

When a species evolves, it can get more repellent and tougher to what kills them off. For exp, if a animal can’t survive due to a carried disease, it will eventually evolve to be stronger against it.

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

The circulatory and respiratory system work together to provide oxygen and remove carbondioxide gas.

How circulatory and respiratory system work together?

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in to bring oxygen and out of the lungs to remove carbondioxde gas from the body. Blood moves into the lungs to bring carbondioxide gas and to load oxygen with the help of pumping of heart.

So we can conclude that circulatory and respiratory system work together to provide oxygen and remove carbondioxide gas.
