b. it points from south to north.
c. it forms loops inside the magnet.
d. There is no field within the magnet.
Answers
The statement that describes the magnetic field inside a bar magnet is it points from south to north. The direction of the magnetic field lines outside is north pole to south pole.
What do you mean by the magnetic field?The magnetic field may be defined as the area around a magnet where a magnetic force is experienced.
The direction of the magnetic field is taken from the outward of the north pole and into the south pole of the magnet. The magnetic field lines begin near the north pole and extended towards the south pole of the magnet.
Therefore, the statement that describes the magnetic field inside a bar magnet is it points from north to south.

Answer: carbon
Explanation:
Carbon is the common “ building block” because of its ability to to bond to 4 different elements at the same time.
The atom that can form a number and variety of molecules because it can bond to 4 other atoms at the same time to make carbohydrates, lipids, nucleic acids and proteins is called carbon.
Carbon atom is the central element that contributes to the formation of biological macro molecules.
Examples of these biological macro molecules that are essential for life are carbohydrates, lipids, nucleic acids and proteins.
Carbon atom is considered a very important atom that can form the number and variety of biological molecules because:
each carbon atom can form four chemical bonds with other atoms,this is because it has sp³, sp², or sp hybridization in its compounds.it forms bond in all these dimensions and make molecules with complicated shapes.Learn more here:

Describe one of the three types of volcanoes we discussed today
Answers
Answer: Shield, Cinder Cone, and Composite volcano.
Explanation: A shield volcano is a volcano that is formed with lava is very runny and spreads to a wide area and then cools to form a shield volcano. These are common at Hawaii.

A forest fire took over this forest ecosystem, burning a majority of the trees in the area. How would this forest fire impact different two different consumer populations in this ecosystem?
Answers
Answer:
Herbivore and carnivores.
Explanation:
This forest fire greatly affected two consumer populations such as herbivores and carnivores because herbivores has no food available due to forest fire. The unavailability of food for the herbivores leads to the decrease in herbivore population that also adversely affected the population of carnivore ( those organisms that feed on herbivores) so both are affected from the forest fire.

Is Selective Breeding and Artificial Selection essentially the same thing? Explain why?
PLEASE GIVE OUT AN EXPLANATION BECAUSE I CANNOT ANSWER MY QUESTION WITHOUT AN EXPLAINTION !!!!
Answers
Answer:
Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding. Natural selection is a natural process. Artificial selection is an artificial or human-made process.
Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. ... Selective breeding can be used to produce tastier fruits and vegetables, crops with greater resistance to pests, and larger animals that can be used for meat.
Explanation:
Hope it is helpful.....
Answer:
Selective breeding and artificial breeding are essentially the same thing because both terms mean to cause changes in animals and plants. Selective breeding and artificial breeding both occur when humans intervene with the natural selection process.
