K

- reducing agent (most likely form

by losing an electron)

C

l

2

- oxidising agent (most likely to form 2

C

−

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).

Answer:

The answer is C they are members of the same species.

A) it isn't correct because they are both the same species which means the same scientific name

B) wasn't even close to being correct, Archaea is part of Prokaryotes which doesn't have a nucleus and they reproduce asexually meaning only one which is making their own offspring that we call clones

D) isn't correct because genus is the same as species

Hope this is correct :)

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.

Answer: D. Iron rusts

Explanation: Rust is made from different chemicals in the air that come in contact with said metal. That could be acidic rain for example. Water freezing is only changing temperature. Sugar dissolving is breaking down molecules. Salt and pepper mixed in a dish is a physical change (also that's just plain evil to some people but that isn't the point). Your answer will be D.

Answer:

Genes are segments of deoxyribonuceleic acid (DNA) that contains the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contains a person’s genes. Genes are contained in chromosomes, which are in the cell nulecus.

Explanation:

Answer:

quick answer

Explanation:

Both genes and chromosomes are inherited from our parents. Genes are like the instruction manual that put us together. They determine our biological predisposition. Chromosomes are the structures that contain our genes, but unlike genes they also determine gender. Chromosomes are made up of two tightly-wound sister chromatids.

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! :)

The object that is used in relative dating is Index Fossil. Thus, option C is correct.

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.

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.

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.

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.
