Can someone explain the Punnett square ?
Answers
Answer:
so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB. next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.
Explanation:
the main points.
in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.add me and message me if you need more help. we can also zoom to figure it out.
Is nature or nurture more important
Answers
Answer:
Yes
Explanation:
cus
it keeps us alive
Nature can go from describing events out of our control, innate feelings, to describing the area we are raised in. Nature can go a long way with raising kids, in comes the theory’s of the “murder gene.” The aforementioned gene is a theory on the “murderous” behaviors in children sociopaths, or psychopaths. This theory exists because of some unexplainable behaviors the children have that were not taught, like hurting animals and lack of empathy.
In a more lose interpretation of Nature it can mean the area children are raised in. Like the different between a trailer park and a mansion. But generally Nature refers to innate, uncontrollable, behaviors.
On the other hand Nurture refers to the actual raising of the child. Referring back to the “murder gene” the question is if you could reverse the effects of the gene in children based on how you raise them. Nurture is also an argument for how kind you should be to your child as they are growing.
Personally I think Nurture is more important, but in all actuality a good balance is best.

A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate
Answers
Answer:
120 joule.
Explanation:
Given
For the stone X
Mass (m) = 2 kg
Height (h) = 2 m
Acceleration due to gravity (g) = 10 m/s²
Then we have the formula to calculate the potential energy
P.E 1 = mgh
= 2 * 10*2
= 40 joule
Now for Stone Y
mass (m) = 4 kg
height (h) = 4 m
acceleration due to gravity (g) = 10 m/s²
Now
P. E2 = mgh
= 4 * 10* 4
= 160 joule
Now the difference between their potential energy is
= P. E2 - P. E 1
= 160-40
= 120 joule

which of the following is an object used in relative dating
A-Carbon 14
B-Daughter Isotope
C-Index Fossil
D-Parent Isotope
i know for sure it’s not A
Answers
Using index fossils for age estimates of rock layers is not a new idea. For example..
1) if you have a fossil trilobite and it was found in the Wheeler Formation.
2) Ammonites were common during the Mesozoic Era. They were not found after the Cretaceous period
The object that is used in relative dating is Index Fossil. Thus, option C is correct.
What is Fossil records?
Fossil records are described as the position of found fossils all through the surface or the layers of the earth. The older the fossils are, the deeper it is found. Fossil records are also considered to be gathered information about the total number of the discovered fossils and the data obtained from them.
Fossil records are important guides to determine how life existed before. If you are to assemble a fossil, you will be able to see and tell the evolutionary changes that happened over the past years. Fossil records are evidences pointing out that life before is totally different from now.
Index fossils are fossils that are common yet were only present for a brief time. By comparing a rock layer to other rock layers, index fossils enable scientists to determine the relative age of a rock layer. Organisms that are still alive today yet have undergone little alteration over millions of years are known as living fossils.
Therefore, The object that is used in relative dating is Index Fossil. Thus, option C is correct.

Cathy's favorite salad dressing is a liquid with particles of salt, pepper, and garlic. When comparing a spoonful of salad dressing to a cell, what would the liquid be equivalent to? What would the particles be equivalent to?
Answers
Answer:
Liquid equivalent to "cytoplasm" and the particles equivalent to "organelles".
Explanation:
While comparing a liquid salad dressing to a cell, the liquid will be equivalent to "cytoplasm" because cytoplasm is a thick solution present in each cell that made up of water, salts, and proteins.
The particles would be equivalent to "organelles" because as particles float in liquid salad adding flavours to the salad likewise organelles are present in a cell floating in the cytoplasm that performs a specific function.
Hence, the correct answer is " liquid will be equivalent to "cytoplasm" and the particles will be equal to "organelles".
