how do scientists use rock layers to date fossils ? USE IN YOUR OWN WORDS.
40 POINTS DONT SKIP !
Answer:
By comparing a fossil to similar rocks and fossils of known ages, relative dating can be used to estimate its age. Absolute dating is a method of determining the precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil itself or, more commonly, the rocks that surround it.

You are trying to determine the mode of inheritance for the mutant curly-winged phenotype in Drosophila. You cross pure-bred wild-type flies with pure-bred mutant (curly-winged) flies and notice that all of F1 has curly wings. You make the scientific hypothesis that the curly-winged phenotype is autosomal dominant to the wild-type wing phenotype. a. If your scientific hypothesis is correct, what ratios would you expect to see in your F2 generation?
Answer:
The correct answer is - In F2 generation we should get a 3:1 ratio of phenotypes. 3 curly dominant, 1 wild type recessive.
Explanation:
In the given case, the cross between pure-bred wild-type flies with pure-bred mutant (curly-winged) flies and it is found that in F1 generation all offsprings are curly wings which means curly wings are dominant over wild-type.
let assume w gene is responsible for wild type and W gene is responsible for the curly wings which is dominant over wild type
W W
w Ww Ww
w Ww Ww
now on self crossing
W w
W Ww Ww
w Ww ww
In f2 generation there are 75% chances of the curly wing and 25% chances of wild type or the ratio of phenotype would be 3:1
Water is transpired through stomata, but carbon dioxide also must pass through stomata into a leaf for photosynthesis to occur. There is evidence that the level of carbon dioxide in the atmosphere has not always been the same over the history of life on Earth. Explain how the presence of a higher or lower concentration of atmospheric carbon dioxide would impact the evolution of stomata density in plants.
Answer:
Escribir en español, por favor.?
During those high-carbon-dioxide times, plants that produce fewer stomata,
when carbon dioxide levels are low, plants need many stomata in order to scrape enough carbon dioxide to survive.
How does carbon dioxide affect water uptake?Plant water use, an increase in atmospheric CO2 means that stomata, or the pores on leaves that exchange gases between the leaf and the atmosphere, do not need to open.
Thus, carbon dioxide levels are low, need many stomata in order to scrape enough carbon dioxide to survive.

Indicate whether each of the following occurs mainly in G1 phase (G), S phase (S), or G2 phase (H) of the cell cycle. Your answer would be a four-letter string composed of letters G, S, and H only, e.g. HGSS. ( ) DNA helicase activation ( ) DNA helicase deposition on DNA at the replication origins ( ) ORC phosphorylation ( ) Licensing of replication origins
Answer:
the answer is S-G-S-G
Explanation:
DNA helicases are enzymes that catalyze the unwinding of the double DNA helix in order to form a replication fork at the origin of replication (i.e., the site where DNA replication starts). DNA replication occurs in a bi-directional manner by two replication forks that move in opposite directions in order to form a replication bubble. The origin of replication is formed during the transition from mitosis to G1 when they are licensed for the subsequent S phase. The origin recognition complex (ORC) is a DNA binding complex that binds to the origin of replication, whose function is to act as a scaffold for the assembly of initiation factors. ORC is phosphorylated during the beginning of the S phase in order to dissociate this complex from chromatin.

In cellular reproduction, ___ ALWAYS occurs in 5’ to 3’ direction
Answer:
DNA replication
Explanation:
DNA replication is the process whereby the genetic material (DNA) duplicates itself into two identical copies. This process must occur prior to any cellular division (meiosis or mitosis) in order to ascertain that each daughter cell gets an even and correct amount of DNA.
The process of DNA replication begins with the unwinding of the double stranded DNA molecule into two single strands of DNA. One strand called leading strand runs from 3'-5' while the other strand runs from 5'-3'. However, DNA replication proceeds in the 5'-3' direction.

how does the structure of simple cuboidal connect to its function
Answer:
Simple cuboidal epithelial tissue is specialized for diffusion and absorption. The reason our kidneys function the way they do is because of the movement of water and salts in and out of the kidney tubules.Likewise, the cuboidal shape of the cells allows greater surface area for absorption to take place.

(Q001) In Lab 2, Exercise 8, you determined the amino acid sequence for the following strand of DNA: A G C A A T C C G T C T T G G T C G T T A G G C A G A A C C That strand has mutated. It is now A G C A A C C C G T C T T G G T C G T T G G G C A G A A C C Use your knowledge of mutation and protein synthesis to answer the following questions. What mutation has occurred
The mutation that has occurred is substitution mutation.
Mutation is defined as the random changes in deoxyribonucleic acid (DNA) that alter genetic information, and so can introduce new characteristics.
Mutation can occur in because of the following reasons stated below:
When exposed to environment saturated with ultraviolet light, it can cause cell mutation; andWhen exposed to certain chemical such as free radicals.A typical example of mutation that occurs in DNA is the substitution mutation.
Protein synthesis is the process used by cells to produce usable specific proteins as directed by the DNA.
The base sequence in DNA determines the sequence of amino acid in peptide.
Substitution mutation occurs when one base is incorrectly replaced in the complementary strand of a DNA.
From the DNA base sequence given,
Cytosine replaced Thymine; andGuanine replaced Adenine.This replacement that occurred will lead to abnormal protein synthesis.

At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started. What does this change demonstrate about the evolution of fishes
Answer:
The correct answer would be - Characteristics can be lost in evolution.
Explanation:
The new evidence helps in developing a new hypothesis. In this case, new evidence proved that the Chondrichthyes diverged after the evolution of bone had started instead of before the evolution started. This process called atavism where an ancestral genetic trait reappears after having lost. This leads to loss of the traits in the evolution
This can take place by knocking the mutation out to overriding the gene by the old gene or overriding the new trait by the old trait during the evolution period.
At one time, Chondrichthyes were thought to have diverged from other vertebrates before the evolution of bone. Now we have concluded that the Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.
What is atavism?
Recurrence in an organism of a trait or character typical of an ancestral form and usually due to genetic recombination. This leads to the loss of the traits in the evolution.
Hence, Chondrichthyes diverged after the evolution of bone had started might be their characteristics lost in evolution according to atavism.

On the colorful map, in general, where is the youngest crust located?
Answer:
The youngest crust (shown in red) is near mid ocean ridges and spreading zones. All three rock types in the earth's crust—igneous, sedimentary, and metamorphic—can also be recycled back to their original molten magma form. This process occurs when oceanic crust is pushed back into the mantle at subduction zones.
