Explanation:
How could one determine if two
unidentified organisms share a common
ancestor?
Answer:
Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.
Explanation:
DNA
They can look at the DNA it's the most common one.
There are 4 pieces of evolution and they are
Fossils , Geography , Embryos / DNA , Anatomy
Fossils: Physical remains of species , Determine age, location, environment
Deeper layers = older
Geography: Proves species share common ancestors, depending on where
they live
DNA: BEST evidence because it’s the MOST ACCURATE
Similarities in the early stages of development
Similarities in DNA
More similarities = closely related
More differences = not related
Anatomy: Compare body parts of different species to see how they evolved
3 different structures:
Homologous (same structure, different function)
Analogous (similar structure, different organisms)
Vestigial (body parts that no longer serve a purpose)
All of that are in evolution

A wave carries from one place to another. Mechanical waves carry energy through
Answer:
Mechanical waves bring energy from one place; the media or space conduct electricity through electromagnetic radiation.
Explanation:
Energy flow is parallel to wave motion. To pass across, the wave needs a source. Electromagnetic radiation bring energy to the surroundings; they conduct electricity via media and room by mechanical waves.

WHAT IS A PUNNET SQUARE?A punnet square is a square diagram that is used to predict the genotypes of a particular cross between two parents using their gametes.
According to this question, a cross involves two parents that are heterozygous for purple flowers. The genotypes of these parent are Ff × Ff.
Therefore, the Punnett square that represents a cross between two parents that are heterozygous for purple flowers are Ff × Ff.

Which best explains the role of plants in the nitrogen cycle?
Answer:
Assimilation
Explanation:
This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. ... When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
is mitosis genetically identical
Answer:
Yes, mitosis is genetically identical.
Explanation:
when mitosis happens, the cells replicate their DNA so when the cell divides in 2, each cell contains the same chain of amino acids so yes the process creates 2 genetically identical cells
What is antibiotic resistance and why should we be

The incidence of cystic fibrosis, a recessive genetic disorder in the Caucasian population of United States, is 1 in every 2,500 individuals. Find the number of heterozygous carriers. (p + q = 1, p2 + 2pq + q2 = 1)
Answer:
The no. of heterozygous carriers = 0.0392
Explanation:
From the given information:
The incidence of this recessive disorder i.e. q² = 1/2500
q² = 0.0004
q = 0.02
From Hardy Weinberg's Equilibrium.
p + q = 1; &
p² + 2pq + q² = 1
∴
p + 0.02 = 1
p = 1 - 0.02
p = 0.98
So, the numbers of heterozygous carrier 2pq is:
= 2 × 0.98 × 0.02
= 0.0392
Describe the process of absolute dating as it relates to igneous rock and the fossil record.
Answer:
Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. ... When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.
Can someone explain the Punnett square ?
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.
