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

option C!!

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.

This is based on what is likely, not so much that the above are known to be oxidising or reducing agents.

The most likely option to be reduced when combined with Al(s) is Fe (iron). Therefore option C is correct.

Reduction refers to the gain of electrons by a chemical species. In this case, we are considering the reduction of ions when combined with solid aluminum (Al(s)).

Aluminum (Al) is more reactive than iron (Fe) in terms of its electrochemical properties. When aluminum reacts with certain metal ions, it tends to displace those ions and undergo oxidation itself. This process is known as a displacement or redox reaction.

Fe (iron) is less reactive than aluminum and can be displaced by aluminum in certain redox reactions. Therefore, it is the most likely option to be reduced when combined with Al(s).

What is osmoregulation?

Answers

Answer:

adalah penghijauwan kota

Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis.[1] The higher the osmotic pressure of a solution, the more water tends to move into it. Pressure must be exerted on the hypertonic side of a selectively permeable membrane to prevent diffusion of water by osmosis from the side containing pure water.

Organisms in aquatic and terrestrial environments must maintain the right concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic if allowed to accumulate in the blood) through organs such as the skin and the kidneys.

a. monohybrid cross for two unlinked traits
b. a monohybrid cross for two closely linked traits
c. a dihybrid cross for two unlinked traits
d. a dihybrid cross for two closely linked traits​

Answers

Answer:

C

Explanation:

The F2 offspring of a cross would follow the ratio of 9:3:3:1 only if the cross is a dihybrid for two unlinked traits.

There is nothing like a monohybrid cross for two traits. A cross involving two traits is a dihybrid cross. Hence, options a and b are out of the equation.

A dihybrid cross for two closely linked traits would produce F2 offspring in another ratio that is different from 9:3:3:1 depending on the linkage map.

Hence, the correct option is C.

Equations for help:
K= C + 273
C= 5/9 (F - 32)
F= (C * 9/5) + 32

Answers

Answer:

9) 75.2°F is less that 82°F so the water is not warm enough for Emma to swim in.

10)Since, 102.2°F is greater than 100°F, Stephen can't go to school today.

Explanation:

9) First, we want to find out 24°C converted to Fahrenheit

           What we want to find                   Equation

                   24°C = ?°F                         F= (C * 9/5) + 32

Second, we have to input our number into our equation

                                    F = (24 × 9/5) +32

Next, we have to use the PEMDAS strategy (ask in the comments if you don't understand!)

       24 × 9/5 =

      24 × 9 = 216                           216÷5 = 43.2

      1   ×   5 = 5

Now, we can't forget to add 32!

43.2 + 32 = 75.2°F

24°C = 75.2°F

75.2°F is less that 82°F so the water is not warm enough for Emma to swim in.

10) For this problem, I'm going to just show the math, so if you have any questions feel free to ask in the comments!

Step 1) 312 = C + 273

           -273        -273

Step 2) 39 = C or C = 39

Step 3) F = (39 × 9/5) + 32

Step 4) F = (351/5) + 32

Step 5) F = 70.2 + 32

Step 6) F = 102.2

Since, 102.2°F is greater than 100°F, Stephen can't go to school today.(and should think about getting a regular thermometer ;)

Answer:

Determining a substance's physical or chemical identity. What are the two main requirements for identification? The adoption of testing procedures that give characteristic results for specific standard materials and the number and type of tests needed to identify a substance to exclude all other substances.

Answer:

Here's a better answer. I know its late though.

Explanation:

There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.

In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.

Next up, the fossil record provides evidence that supports common ancestry and evolution.  The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.

NesbitIt all began with Effie's getting something in her eye. It hurt very much indeed, and it felt something like a red-hot sparkonly it seemed to have legs as well, and wings like a fly. Effie rubbed and criednot real crying, but the kind your eye does all by itself without your being miserable inside your mindand then she went to her father to have the thing in her eye taken out. Effie's father was a doctor, so of course he knew how to take things out of eyes.When he had gotten the thing out, he said: "This is very curious." Effie had often got things in her eye before, and her father had always seemed to think it was naturalrather tiresome and naughty perhaps, but still natural. He had never before thought it curious.Effie stood holding her handkerchief to her eye, and said: "I don't believe it's out." People always say this when they have had something in their eyes."Oh, yesit's out," said the doctor. "Here it is, on the brush. This is very interesting."Effie had never heard her father say that about anything that she had any share in. She said: "What?"The doctor carried the brush very carefully across the room, and held the point of it under his microscopethen he twisted the brass screws of the microscope, and looked through the top with one eye."Dear me," he said. "Dear, dear me! Four well-developed limbs; a long caudal appendage; five toes, unequal in lengths, almost like one of the Lacertidae, yet there are traces of wings." The creature under his eye wriggled a little in the castor oil, and he went on: "Yes; a bat-like wing. A new specimen, undoubtedly. Effie, run round to the professor and ask him to be kind enough to step in for a few minutes.""You might give me sixpence, Daddy," said Effie, "because I did bring you the new specimen. I took great care of it inside my eye, and my eye does hurt."The doctor was so pleased with the new specimen that he gave Effie a shilling, and presently the professor stepped round. He stayed to lunch, and he and the doctor quarreled very happily all the afternoon about the name and the family of the thing that had come out of Effie's eye.But at teatime another thing happened. Effie's brother Harry fished something out of his tea, which he thought at first was an earwig. He was just getting ready to drop it on the floor, and end its life in the usual way, when it shook itself in the spoonspread two wet wings, and flopped onto the tablecloth. There it sat, stroking itself with its feet and stretching its wings, and Harry said: "Why, it's a tiny newt!"The professor leaned forward before the doctor could say a word. "I'll give you half a crown for it, Harry, my lad," he said, speaking very fast; and then he picked it up carefully on his handkerchief."It is a new specimen," he said, "and finer than yours, Doctor."It was a tiny lizard, about half an inch longwith scales and wings.So now the doctor and the professor each had a specimen, and they were both very pleased. But before long these specimens began to seem less valuable. For the next morning, when the knife-boy was cleaning the doctor's boots, he suddenly dropped the brushes and the boot and the blacking, and screamed out that he was burnt.And from inside the boot came crawling a lizard as big as a kitten, with large, shiny wings."Why," said Effie, "I know what it is. It is a dragon like the one St. George killed."And Effie was right. That afternoon Towser was bitten in the garden by a dragon about the size of a rabbit, which he had tried to chase, and the next morning all the papers were full of the wonderful "winged lizards" that were appearing all over the country. The papers would not call them dragons, because, of course, no one believes in dragons nowadaysand at any rate the papers were not going to be so silly as to believe in fairy stories. At first there were only a few, but in a week or two the country was simply running alive with dragons of all sizes, and in the air you could sometimes see them as thick as a swarm of bees. They all looked alike except as to size. They were green with scales, and they had four legs and a long tail and great wings like bats' wings, only the wings were a pale, half-transparent yellow, like the gear-boxes on bicycles.What words best describe the tone set by the narrator in the opening lines?
