Mendel discovered about the principles of heredity: A) Individuals get one factor for a trait from each parent and C) A dominant factor can hide the expression of a recessive factor when both are present.
What are Mendel's discoveries revolutionized the field of genetics?Gregor Mendel uncovered the basic principles of inheritance through his study on pea plants. He concluded that genes are inherited from each parent as separate, paired units. Mendel observed how parental genes separated and if they showed up as dominant or recessive qualities in the children. He was aware of the mathematical patterns passed down from one generation to the following.
Mendel's Laws of Heredity are typically expressed as follows:
1) The Law of Segregation: A gene pair determines each inherited trait. So that each sex cell only contains one of a pair of parental genes, parental genes are arbitrarily distributed to the sex cells. Therefore, when sex cells combine to form offspring during fertilisation, they receive one genetic allele from each parent.
2) The Law of Independent Assortment: Different qualities' genes are grouped independently of one another so that inheriting one trait does not affect inheriting another.
3) The Law of Dominance states that an organism with two possible gene variants will express the dominant form.

Explanation:
The rock cycle works by the rocks moving around. Weathering and erosin makes sediment or something like sand, that sand is put under a lot of pressure until it becomes a solid mass. After that heat and more pressure are added to the rock to make it metamorphic. after that it is heated again until it becomes magma. the ignious rock is made by the cooling of the lava( its lava when it gose above ground). Then the whole cycle repeats.

When a car suddenly stops at a red light, a book lying on the car seat slides forward. Why does the book continue to move forward?
A: The car moves in reverse more rapidly than the book.
B: The friction of braking transfers energy to the book
C: The book’s inertia causes it to continue moving
Answers
Answer:
C
Explanation:
The answer is c because Newton’s third law states “ for every action there is an equal and opposite reaction.” Since the car quit moving the book did not stay at rest because there was a reaction.
Answer:
C
Explanation:
Newton's 1st law of motions states : " Intertia: A objects resistance to change. More mass= more intertia. Less mass= Less intertia.
it ALSO states that an object at rest will stay at rest, until an outside forces acts upon the object, forming an unbalanced force.
The car stopping suddenly is the outside force, and the book sliding forward is the intertia to change.

An astronaut floating in space throws a wrench forward with the force of 10 N.
How much force does the wrench apply to the astronaut?
A. greater than 10 N
B. less than 10 N
C. zero; the wrench does not apply a force
D. exactly 10 N
Answers
The wrench applies greater than 10 N force to the astronaut. The correct option is A.
What is Newton's third law of motion?Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When the astronaut throws the wrench forward with a force of 10 N, the wrench will apply an equal and opposite force of 10 N to the astronaut in the opposite direction.
Here other options are,
Option B. Less than 10 N is not true because the force applied by the wrench to the astronaut is equal and opposite to the force applied by the astronaut to the wrench, which is 10 N.
Option C. zero; the wrench does not apply a force is not true because the wrench is exerting a force on the astronaut in the opposite direction to the direction in which the wrench is thrown.
Option D. exactly 10 N is not true because the force applied by the wrench to the astronaut is equal and opposite to the force applied by the astronaut to the wrench, which is 10 N, and the two forces act in opposite directions.
Therefore, the force applied by the wrench to the astronaut is greater than 10 N.

Sickle cell anemia is a recessive trait (aa) which causes a red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen to the body. Individuals with the genotype AA have normal red blood cells. Those individuals who are heterozygous for the trait usually have no symptoms of sickle cell disease, but carry the sickle cell trait and can pass it on to their offspring. However, those individuals who carry the sickle cell trait have some protective advantage against malaria, making this a common genotype in malaria prone areas. The graph illustrates the frequencies of two genotypes, AA and Aa, over many generations. Select ALL the conclusions you can draw from the graph provided.
A) There appears to be random mating between genotypes.
B) There is no selective advantage for one genotype over another.

A cyclist turns a corner with a radius of 50m at a speed of 10m/s. The cyclist's acceleration is 2 m/s².
What is acceleration?The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.
a = v²/r
a = (10m/s)² / 50m

you went to move a 41 kg bookcase to a different place in the living room. if you push with a force of 65 N and the bookcase accelerates at 0.12 m/s2 what is the coefficient of kinetic friction between the bookcase and the carpet?
Answers
Answer:
the force of friction = fk = (uk)n = 402(uk)
the net force acting to accelerate bookcase = ma = (41)(0.12) = 4.9 N
the {assumed horizontal} push force = 65 N
so
65 - fk = 4.9
fk = 65 - 4.9 = 60 N
