Answer: The full explanation below.
Explanation: The advantage of Relative dating is it can tell if a rock is older or younger that a certain object where the age is also not certain making it easier to tell when the other object was from, however it dose not give an exact age of the rock. Absolute dating is different because it gives you the exact age of the rock, but does not aid in find the age of any artifacts that can be found around it. Hope this helps! :D
Absolute dating establishes the exact age of a historical relic, whereas relative dating determines the order of age of several samples. Absolute dating is therefore a quantitative measurement, whereas relative dating is a qualitative measurement.
What is dating?To date ancient events, geologists commonly use radiometric dating methods, which are based on the natural radioactive decay of certain elements such as potassium and carbon.
Relative dating is used to order geological events and the rocks they leave behind. The limitation of relative dating of fossils is that it does not provide the absolute age of the preserved fossils.
Absolute dating methods take physical properties of an object and use them to calculate its age.
Despite the fact that scientists exercise extreme caution when dating objects, recent studies show that they still make mistakes.
Because of incorrect setup, the dates used with this method are incorrect. The dates may not be consistent over long periods of time.
Thus, above mentioned are some advantages as well as disadvantages of two types of radiometric dating.

PLEASE HELP I HAVE 20 MINS LEFT. After performing an investigation, a scientist produced results that did not support the hypothesis. Another scientist does the same experiment and her results do support the hypothesis. What should the scientists'
next steps be to make sure any claim made regarding these investigations is valid?
Change the hypothesis to match the results.
Choose data from both investigations that supports the desired outcome.
Publish the results so the public can decide which investigation is correct
Compare and discuss the results with other scientists to determine future research plans,
Answer:
okay so im not a 100 percent sure but i belive it is compare and disscusse the results with other sintist to determin future reserch plans if it is not that then it is publish the result
Explanation:
Answer:
The last one.
Explanation:
Not every investigation gets the same results, she cant say the other scientist is wrong, because without comparing results she cant look for stuff that supports ''the desire outcome'' therefore the correct answer is D, she should compare and discuss the results with the other scientist that worked on the same topic, and determine research with both results to explore what's wrong or what's missing. Hope that helps!
A man, whose father had normal fingers, has inherited syndactyly, an autosomal dominant trait. He is married to a normal woman. What is the probability of producing an offspring that has webbed fingers or toes
Answer:
The correct answer is - 50 % or 1/2 chances.
Explanation:
As it is given that the father of the man with syndactyly had normal father which is only possible if he had two recessive alleles as it is an autosomal dominant condition, therefore, it also means the mother of man must have one or two dominant alleles for the disease and one is passes to the man, so the man is heterozygous for the diseases gene.
Man - Ss married to a normal woman which means she has both recessive alleles that is ss.
S s
s Ss ss
s Ss ss

Which organelle is X?
What substance is found at Y?
Answer:
Organelle X is the nucleous.
Y is where you can find Cytoplasm
Explanation:
Which of the following substances is the most acidic?
a substance that has a pH of 7
a substance that has a pH of 2
a substance that has a pH of 8
a substance that has a pH of 5
pH=-lg[H+]
from the formula of the pH you can deduct that the lower the pH the more hydrogen protons are released. The easier it is for a compound to release protons the more acidic it is. Therefore the correct answer is a substance that has a pH of 2
The substance with the lowest pH would be highly acidic. Therefore, the substance with pH 2 is the most acidic.
A pH scale is useful to express the concentration of hydronium ions on a logarithmic scale. The negative logarithm (with base 10) of the activity of the hydrogen ion (H+) is used to determine the pH of acids and bases.
The substance with pH 7 has a neutral pH according to the pH scale.
A substance with pH 8 is slightly basic, while a substance with pH 5 is slightly acidic.
Therefore, a substance with pH 2 is most acidic is the correct answer.

En la meiosis, el entrecruzamiento (recombinación génica entre cromosomas) o crossing over ocurre durante la: *
Answer:
Profase I
Explanation:
La Profase I es la primera etapa de la meiosis en la cual el material genético se condensa para formar los cromosomas y se desarrolla el huso acromático (huso meiótico). El entrecruzamiento, también conocido como sobrecruzamiento o crossing-over (por su nombre en inglés), es un proceso que consiste en el intercambio de material genético entre cromátidas no hermanas de cromosomas homólogos. El entrecruzamiento se produce durante la Profase I, es decir, durante el período inicial del primer ciclo celular meiótico (meiosis I). El sobrecruzamiento tiene una importancia fudamental desde el punta de vista evolutivo ya que este fenómeno incrementa la diversidad genética de las gametas obtenidas mediante este proceso.
2. What is a feature of transcription? Both strands of a DNA molecule act as a template for mRNA. Nucleoside triphosphates become nucleotides by losing three phosphates. RNA polymerase binds to the promoter region. The sense strand acts as a template for mRNA.
Answer:
RNA polymerase binds to the promoter region
Explanation:
The correct answer would be that the RNA polymerase binds to the promoter region.
Transcription is a process during which mRNA is synthesized using the anticoding strand of the DNA as the template. The process is initiated when an enzyme known as the transcription factor binds to the TATA element within the promoter region - a region that signifies the beginning of a gene. This enables the RNA polymerase enzyme to also bind to the promoter leading to the formation of the initiation complex.
The RNA polymerase functions as a copier of the DNA nucleotides to RNA nucleotides during the elongation process of transcription.

Explanation:
hope this helps! good luck!
Helen is studying the growth of two different types of plants. Sunlight is an independent variable as it varies and the number of new leaves is the dependent variable. Thus, Option A is correct.
What are the independent and dependent variables?The Independent variable is the variable that is changed in a scientific experiment. Temperature is an example of an independent variable.
The dependent variable depends on other variables. The amount of leaves that grow on the tree is determined by how much sun the plant is receiving. The amount of sunlight may vary, therefore, it is the independent variable and the number of new leaves is the dependent variable.
The amount of shade that is given is the independent variable. The intensity of sunlight may change day by day. The amount of leaves that grow on each plant is the dependent variable. Therefore, Option A is correct.

Use the drop-down menus to select the storm that causes each environmental hazard.
Flash flood
Storm surge
Is the answer b
Explanation:
And d
Environmental hazard such as flash flood is due to thunderstorms and storm surge is due to the hurricanes in nature.
What is an environmental hazard?The majority of environmental hazards such as flash flooding is brought about by the thunderstorms that move slowly, move over the same region repeatedly over time, or bring heavy rainfall from the hurricanes and tropical storms.
On the rare occasions, ice or floating debris may build up near a natural or the artificial obstacle and impede the movement of water. The unexpected increase in the water level caused by a storm's winds is known as storm surge (environmental hazard).
Storm surges and the powerful waves can cause major significant property damage and the fatalities near the shore line.
Therefore, the storm surges and the flash flood are environmental hazards.
