Evolution
What is evolution?
The change in heritable traits over generations
What is Newton's first law?
An object in place will stay in place and an object in motion will stay in motion unless a force is acted upon it.
What happens when 2 same magnetic poles are near each other?
They repel and push each other away
What is a punnet square and what do they represent?
A Punnett square is a visual tool used in genetics to predict the possible genotypes of offspring resulting from a cross between two parents
What year did tik tok come out?
September 2016
What do you know if two fossils have similar structures?
If two fossils have similar structures we know that they have a common ancestor
If 50N is being applied to the left and 25N is being applied to the right what is the overall force?
The overall force being applied is 25N
50N - 25N = 25N
What do magnetic field lines tell us about the magnetic force?
It tells us the direction and strength of the force at the given point
Y represents dominant yellow flower, y represents recessive yellow flower. P if dominant pink flower, p is recessive pink flower. The two alles are YY and Pp.
Is there any possibility that the flower will be yellow?
Yes because these is a 50% chance that the alleles will be a Dominant Yellow and a recessive pink.
What was the most used fidget in 2020?
Pop its
What is a Paleontologist?
A scientist who studies fossils in order to understand the ancient history of life on Earth
If two forces are being applied to an object that are not of the same strength what type of force would that be?
The force being applied would be an unbalanced force.
If there is Iron in between a north pole and south pole will they attract or repel? (Draw the magnetic field lines)
The iron will attract both the north and south pole together.
The two allele combinations are BB and Gg for eye color B is brown dominant b is brown recessive G is green dominant and g is green recessive create a punnett square that matches and writes the percentage for each combination.
Combinations:
BG, BG, Bg, Bg,
50% BG and 50% Bg
What made Lebron James famous? (Not the meme)
LeBron James achieved immense fame due to his exceptional basketball talent
What are evolutionary trees?
Evolutionary trees, or phylogenetic trees, are diagrams that show the relationships between different species.
A soccer ball already had a force of 50N applied to its left and then a soccer player applied a force of 60N to the left. What is the force being applied and in what direction.
The total force being applied on the soccer ball is 110N to the left.
There are 3 magnets 2 north poles facing a south pole. In the end will all 3 magnets repel or attract.
In the end they would attract, the two north poles would repel but their combined repulsion will be less than than the attraction between the north and south pole
The two alleles combinations are rr and Bb for hair color. R is red recessive, B is black dominant, b is black recessive. Create a punnet square that matches, write the percentage, and what does that tell you about the offspring’s hair color.
Combinations:
Br, Br, br, br,
50% Br and 50% br
The Punnett square shows that all offspring will have the genotype Br, meaning they will all have black hair. The predicted percentage is 100% black hair
True or false: Bananas are radioactive
True
What does an evolutionary tree tell you about the changes in a species?
Evolutionary tress illustrate how species change and evolved from common ancestors.
What is the definition of each Law of Newton?
First Law-
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.
Second Law-
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Third Law-
For every action, there is an equal and opposite reaction.
What is electromagnetism and give an example
the interaction of electric currents or fields and magnetic fields.
The two allele combinations are DD and Gg for hair color D is brown dominant d is brown recessive G is black dominant and g is black recessive create a punnett square that matches and writes the percentage for each combination.
The Punnett square shows that all offspring will have brown hair. The possible genotypes are
DG 50%
Dg 50%
What was the most trending movie in 2023?
Spider-man: Across the spider verse
