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.

1.What were some characteristics that the finches developed to give them an advantage in surviving?

2.How do you think that the one species of finch evolved into many different species, each with its own advantages?

3. In what ways do these advantages help the finches to survive and reproduce?

4. What might have happened if the finches didn't evolve into many different species?

Answers

Answer:

1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection

3.  Medium ground finches with larger beaks could take advantage of alternate food

The statement which best describes the relationship between DNA and genes is that Genes are segments of DNA. Thus, the correct option for this question is C.

What is DNA?

DNA stands for deoxyribonucleic acid. It may be defined as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.

DNA is responsible for building and maintaining your human structure. While Genes are segments of your DNA, which give you physical characteristics that make you unique. Together, your body has a complete instruction manual that tells your cells how to behave.

Therefore, the statement which best describes the relationship between DNA and genes is that Genes are segments of DNA. Thus, the correct option for this question is C.

16. In which of the following situations are the phenotypes of F2 offspring expected to follow
the ratio of 9:3:3:1?
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.

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.

K

C

2

- oxidising agent (most likely to form 2

C

l

by gaining electrons)

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).

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 ;)

Hope this Helps! :)
