What is the difference between a cladogram and a phylogenetic tree
Cladograms are concerned with the way organisms are related to common ancestors through shared characteristics.
What is Phylogenetic Tress?Phylogenetic trees compare organisms over evolutionary time and the amount of change that has occurred over time to figure out the relationships.
The species or groups of interest are located at the ends of lines known as the tree's branches in a phylogenetic tree.
As an illustration, the phylogenetic tree below depicts relationships between five species that are located at the endpoints of the branches, A, B, C, D, and E.
Therefore, Cladograms are concerned with the way organisms are related to common ancestors through shared characteristics.

When classifying organisms using a dichotomous key which category is the narrowest or will contain the least number of organisms
Life is classified in many levels from less specific to more specific:
Domain (bacteria, archaea, eukaryotes)
Kingdom
Phylum
Class
Order
Family
Genus
Species
The domains 'contains' the most number of organisms, species contain the least number of organisms.
Answer:
Species
Explanation:
The highest taxonomic category is domain followed by kingdom, phylum, class, order, family, genus and species. Among this, being the highest category, domain includes maximum number of organisms. On the other hand, being the lowest taxonomic category, species would include least number of organisms.
Example: Domain “eukarya” includes all the eukaryotic organisms while species "sapiens" includes only present day human beings.

All living things use nitrogen to
Final answer:
All living things use nitrogen to create amino acids, proteins, and nucleic acids. Nitrogen in the atmosphere is unusable for most organisms until it is fixed by certain microorganisms into compounds like nitrates or ammonia. Plants absorb these compounds and are then consumed by animals, passing the nitrogen through the food chain.
Explanation:
All living things use nitrogen to synthesize important biological molecules necessary for life. Nitrogen is critical for the production of amino acids, which are the building blocks of proteins, as well as nucleic acids such as DNA and RNA. While the atmosphere is approximately 79% molecular nitrogen (N2), this form of nitrogen is largely inaccessible to most organisms because they are unable to break the strong triple bond that N2 molecules possess.
Therefore, the nitrogen must be 'fixed' into a more usable form, such as nitrates or ammonia. This nitrogen fixation is performed by certain microorganisms, including those in the species Rhizobium, which are found in root nodules of legumes, and cyanobacteria present in soil and water environments. Once nitrogen is fixed, plants can absorb it and incorporate it into organic compounds. Herbivores and carnivores then obtain their necessary nitrogen by consuming plant material or other animals.

Scientists often use bacteria when making recombinant DNA since the bacteria can produce the desired protein quickly and in large quantities. They will often insert the foreign gene into a small circular piece of bacterial DNA, which is separate from the main chromosome. What is this piece of DNA called?
A. Clone
B.Plasmid
C.Genome
Option b is correct. The small circular piece of bacterial DNA used for inserting a foreign gene is called a plasmid. It is a vehicle used in molecular cloning for replicating and expressing the inserted gene in bacterial cells.
Scientists often use bacteria to produce recombinant DNA, which in turn is used to create multiple copies of genes or express proteins. When introducing a foreign DNA into bacteria, the DNA fragment is first inserted into a plasmid. A plasmid is a small circular DNA molecule that can replicate independently of the bacterial chromosomal DNA. These plasmids are also known as vectors as they can carry foreign DNA from one organism to another, and, thus, used as a vehicle for gene cloning. Once inserted, the foreign DNA is replicated along with the rest of the bacterial DNA through the division of the bacterial cells.
Answering the student's question, the small circular piece of bacterial DNA, separate from the main chromosome, into which a foreign gene is inserted is called a plasmid. Therefore, the correct option is B. Plasmid.
Explain how the Che molecules allow a bacterium to move towards or away from a chemical source
Ans.
The Che proteins (chemotaxis proteins) are cytoplasmic proteins that play an important role in signal transduction pathways between the repellent or attractant and flagellar motor switch of a bacterium. Bacterial cell membranes contain different chemoreceptors for different attractants and repellents.
When a repellent or attractant binds with a chemoreceptor, stimulation of signal-transduction pathway occurs. It sends a signal to the cytoplasmic domain of receptor, which interacts with Che proteins, present at cytoplasm. The rate of auto-phosphorylation decreases when an attractant binds with receptor, while the rate of auto-phosphorylation increases when an attractant binds with receptor.
Thus, 'the attractant enhances smooth swimming and counterclockwise rotation towards the chemical source, which repellent enhances tumbling clockwise rotation away from a chemical source.'
What are linked genes?
genes on different chromosomes that are inherited together
genes on the same chromosome that sort independently
genes on different chromosomes that always control the same traits
genes on the same chromosome that are inherited together
Question: What are linked genes?
Answer: genes on the same chromosome that are inherited together
Explanation: this is because these genes are not inherited by themselves
question answered by
(jacmorris04)
Linked genes are genes on the same chromosome that are inherited together during cell division because they are located closely together. These genes often lead to unique patterns of inheritance.
Explanation:Linked genes are genes that are located on the same chromosome and thus are likely to be inherited together during the cell division process. This is because they are situated so close to one another on the same chromosome that they do not separate independently, a key tenet of Mendelian genetics. Because of this, linked genes often show genetic traits or phenotypes that violate the principle of independent assortment, leading to unique patterns of inheritance.
For example, in fruit flies, the gene for eye color and the gene for wing size are linked genes. This means that if a parent has red eyes and large wings, their offspring are much more likely to also have red eyes and large wings because these traits are often inherited together due to the close proximity of their respective genes on the chromosome.

which type of chemical bond holds the atoms together within a molecule of water
Final answer:
Within a water molecule, atoms are held together by covalent bonds, where the oxygen and hydrogen atoms share electrons. This bond is crucial for the molecule's structure, distinguishing it from hydrogen bonds, which form between different water molecules.
Explanation:
The type of chemical bond that holds the atoms together within a molecule of water is the covalent bond. Covalent bonds are a form of chemical bond where atoms share electrons to achieve a more stable electron configuration. In a water molecule, this bond occurs between the oxygen atom and each hydrogen atom. The shared electrons spend more time closer to the oxygen atom due to its higher electronegativity, creating a partial negative charge near the oxygen and a partial positive charge near the hydrogen atoms. This uneven distribution of charge within the molecule contributes to the formation of hydrogen bonds between adjacent water molecules, but it is important to distinguish that the covalent bond is what holds the atoms together within a single water molecule, while hydrogen bonds are intermolecular forces that occur between water molecules.
The specific type of chemical bond that holds the atoms together within a molecule of water is a covalent bond.
In a water molecule (H₂O), there are two covalent bonds formed between the oxygen (O) atom and the two hydrogen (H) atoms. Covalent bonds involve the sharing of electrons between atoms to achieve a more stable electron configuration. In the case of water, oxygen has six electrons in its outer shell and needs two more to complete its octet. Each hydrogen contributes one electron, forming a shared pair of electrons with the oxygen atom. The sharing of electrons in covalent bonds allows each atom to attain a more stable state by filling its outer electron shell. In water, this results in a bent or V-shaped molecular geometry. It's important to note that the electrons are not transferred from one atom to another, as in ionic bonds, but are shared between the atoms. The strength of covalent bonds is determined by the sharing of electrons, with single, double, or triple bonds representing different levels of electron sharing.
In summary, within a molecule of water, the atoms (oxygen and hydrogen) are held together by covalent bonds, where electrons are shared to achieve a more stable configuration for each atom.
QUESTION
What specific type of chemical bond is responsible for holding the atoms together within a molecule of water?
What are the three forms of nitrogen found in an aquarium and their formulas?
Answer:- The three forms of nitrogen in an aquarium are
1. Nitrate NO3-
2Nitrite NO2-
3. Ammonia NH3
Explanation:
The waste products produced by fishes is broken down into ammonia which is highly toxic for the fishes present in the aquarium.The nitrogen cycle takes place in the aquarium to convert this toxic ammonia into lesser toxic forms.This nitrogen cycle proceeds to convert ammonia into nitrite and then nitrite into nitrate. This means the cycle is ammonia——>nitrite——> nitrate.This conversion takes place with the help of several bacteria which establish a colony in the filter bed of the aquarium in the presence of ammonia .Then these bacteria help to finally convert ammonia to nitirite and then to nitrate.The bacteria that convert ammonia to nitrite are oxygen loving bacteria called as Nitrosomonas. The nitrite so formed is less toxic as compared to ammonia.The conversion of nitrite to nitrate takes place by the bacterial species called as Nitrobacter . The nitrate thus formed is harmless for the aquarium fishes at low levels.Thus, in this nitrogen cycle we can see that there are three different forms in which nitrogen is present- ammonia, nitrate and nitrite.

1. A
2. B
3. A
I am pretty sure this is correct
The two processes that are most responsible for the decrease in the height of the Appalachian Mountains include weathering and erosion.
The statement that explains why earthquakes occur more frequently in California than in Massachusetts is due to the fact that California is located on the boundary of two crustal plates, but Massachusetts is not.
The feature that forms when an oceanic plate has been moving over a hot spot for millions of years is that volcanoes form as lava erupts through the oceanic plate.
It should be noted that erosion and weathering reduce the height of rocks and this can lead to a decrease in the height of the Appalachian Mountains.
In conclusion, the correct options are A, B, and A.

Enzymes are very sensitive to temperature and pH.
An enzyme will not function well or at all if it is at the wrong temperature or pH level. However, there is no set range for all enzymes; every enzyme is different and has their own range. For example, the pH levels under which stomach enzymes work best would be vastly different from the pH levels under which intestinal enzymes work.
