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
4. three species of Darwin's tree finches have been known to inhabit Floreana but no birds singing that song on Floreana have been heard in many years.

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

What absorbs water in the digestive system
Your answer is Small Intestine.
Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
Answer: Small intestine
Either you put small intestine in the wrong place, or you're able to put the same one for multiple questions

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.
Light-dependent and light-independent reactions occur at the same time. True or False
true because they are driven by the ATP made by the light-dependent reactions. Both systems shut down in the dark. The light-independent reactions can last a little longer if there is ATP remaining in the chloroplast.

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.

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.

What is a recessive allele?
Answer:
A type of allele that when present on its own will not affect the individual. Two copies of the allele need to be present for the phenotype to be expressed.
Explanation:
Answer:
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. An allele is a specific variation of a gene, or specific segment of DNA. Different alleles produce slightly different proteins, which function in different ways.

Can someone explain the Punnett square ?
Answer:
so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB. next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.
Explanation:
the main points.
in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.add me and message me if you need more help. we can also zoom to figure it out.

−
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).
