Why do scientists think that cuttlefish
have the biggest brain to body ratio of all
invertebrates (animals without a spine)?
Answer:
Due to its high intelligence.
Explanation:
Scientists think that cuttlefish have the biggest brain to body ratio of all invertebrates that allows it to sense sight, smell, and sound that comes to it in the form of pressure waves. Due to this big brain, cuttlefish are very intelligent so due to its intelligence the scientists thinks that cuttlefish has the biggest brain as compared to other big vertebrates such as octopus.

B. Sugar dissolves in water.
C. Salt and pepper are mixed in a dish.
D. Iron rusts.
Answer:
i think it is d
Explanation:
sorry if wrong
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. Iron rusts.

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
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.

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.

how has selective breeding contributed to a wide variety of dog breeds?
Answer:
In the same way that inbreeding among human populations can increase the frequency of normally rare genes that cause diseases, the selective breeding that created the hundreds of modern dog breeds has put purebred dogs at risk for a large number of health problems, affecting both body and behavior.

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

What is it about these dogs that is true?
(A) They have different scientific names.
(B) They belong to the domain Archaea.
(C) They are members of the same species.
(D) They are different genus
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 :)

NEED HELP WITH THESE 4 QUESTIONS WILL GIVE BRAINLIST!!!
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?
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

K
- reducing agent (most likely form
K

by losing an electron)
C
l
2
- oxidising agent (most likely to form 2

−
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).
