based on your cladogram: 1 what would be the symplesiomorphy for the clade that includes squid and birds? 2 what would be the synapomorphy that distinguised lizards and salamanders?
Answers
1. The symplesiomorphy for the clade including squid and birds is the possession of a beak-like structure.
2. The synapomorphy distinguishing lizards and salamanders is the presence of legs.
1. The symplesiomorphy for the clade that includes squid and birds would be the possession of a beak-like structure. Both squid and birds have evolved independently to develop beak-like structures, but this characteristic can be traced back to their common ancestor. While the beak structures serve different functions in each group, the presence of a beak-like structure is a shared primitive trait inherited from their common ancestor.
2. The synapomorphy that distinguishes lizards and salamanders is the presence of legs. Both lizards and salamanders belong to the class Reptilia, but they represent different orders. Despite the vast diversity within reptiles, lizards and salamanders share a common derived trait of having four legs. This characteristic sets them apart from other reptilian groups like snakes and turtles, which have either lost or modified their limbs over time. The presence of four legs in lizards and salamanders is a synapomorphy, indicating their shared evolutionary history and close relationship within the reptilian clade.

if dna was loaded at the top of a gel but the positive and negative poles were accidentally reversed, what would happen? a. all of the dna molecules would move towards the top of the gel. b. all of the dna molecules would move towards the bottom of the gel. c. small dna molecules would move towards the top of the gel and large dna molecules would move towards the bottom of the gel. d. small dna molecules would move towards the bottom of the gel and large dna molecules would move towards the top of the gel.
Answers
All of the DNA molecules would move to the top of the gel if DNA was loaded at the bottom of a gel but the positive and negative poles were accidentally switched. So option A is the right answer.
DNA fragments of different lengths can be distinguished using electrophoresis. When an electric current is applied to the gel, DNA will migrate toward the positively charged electrode because it is negatively charged. Because shorter DNA strands move through the gel more quickly than longer ones, the DNA fragments are arranged in size order. Due to their negative charges, DNA and RNA are drawn toward the positively charged end of the gel.
Therefore, if DNA were placed at the top of the gel but the positive and negative poles were accidentally switched, we can say that all DNA molecules would move to the top of the gel.

Answers
The link between adenosine diphosphate (ADP) and adenosine triphosphate (ATP) is best explained by the fact that when energy is added, ADP interacts with a phosphate group to form ATP. The right Option is (c).
The mitochondria of cells are thought of as the powerhouse since ATP is produced there. As seen in the reaction below, ATP is produced when ADP reacts with an inorganic phosphate and an energy source to generate ADP;
Pi + energy + ATP + H2O = ADP + inorganic phosphate
One adenine, one sugar, and two phosphates make up the biological molecule known as adenosine diphosphate (ADP). Its most crucial function is the creation of ATP, the most vital energy molecule in living cells, when it is coupled with a phosphate molecule. An enzyme called ATP synthase produces ATP during oxidative phosphorylation. Specifically, protons travel through the protein and cause a conformational change once a proton gradient is established. ADP and inorganic phosphate are then combined by ATP synthase to form an ATP molecule.

A substitution mutation occurred and changed the 5th base in the DNA from a C to a T. Write the sequence of RNA codons that would result from this kind of mutation. **Separate each codon with a space. TACACGCAATTACCAGGGTAGCCATTGATT
Answers
The sequence of RNA codons resulting from the substitution mutation that changed the 5th base in the DNA from a C to a T is AUGUGCGUUAUCCAGGGUAGCCAAUUGA.
In DNA, the base C (cytosine) pairs with G (guanine), while in RNA, the base C pairs with G. However, due to the substitution mutation, the original C is replaced by a T (thymine) in the DNA sequence.
In RNA, thymine is replaced by uracil (U). Therefore, the RNA codons corresponding to the mutated DNA sequence can be derived by replacing each T with U and maintaining the sequence order.
The original DNA sequence TACACGCAATTACCAGGGTAGCCATTGATT would have the corresponding RNA codons AUGUGCGUUAUCCAGGGUAGCCAAUUGA. Each codon consists of three bases and represents a specific amino acid or a start or stop signal in the translation process of protein synthesis.

All of the following functions occur in the stomach in the presence of protein, EXCEPT: (a) G-cells secrete gastrin (b) Chief cells secrete pepsin (c) enteric neuron is activated (d) All the answers are true (e) Parietal cells secrete H natio
Answers
Regarding functions occurring in the stomach in the presence of protein: All the answers are true, option d is correct.
G-cells secrete gastrin: Gastrin is a hormone that stimulates the release of gastric acid and enhances gastric motility, which aids in protein digestion.
Chief cells secrete pepsin: Pepsin is an enzyme released by chief cells that breaks down proteins into smaller peptides, facilitating their digestion.
Enteric neuron is activated: The enteric nervous system controls various digestive functions, including the regulation of gastric acid secretion and muscle contractions in the stomach. In the presence of protein, the enteric neurons are activated to coordinate these processes.
Parietal cells secrete HCl: Parietal cells are responsible for secreting hydrochloric acid (HCl) into the stomach. HCl creates an acidic environment that helps activate pepsin and facilitates protein digestion, option d is correct.

Answers
If the climate in a tropical area suddenly becomes arid, the plants that reproduce ase-xually would be at risk of drying out and dying.
This is because asexual reduplication doesn't involve the exchange of inheritable material, and so the shops aren't suitable to acclimate to the new environment and come more tolerant of the thirsty climate. Without the exchange of inheritable material, the shops can not evolve to come more resistant to extreme conditions.

Which blow toward the low-pressure areas of the westerlies?a jet streamsb trade windsc horse latitudesd polar easterlies
Answers
The correct answer to the question is the polar easterlies. The westerlies refer to the prevailing winds that blow from west to east in the mid-latitudes of both hemispheres.
These winds are caused by the Earth's rotation and the unequal heating of the atmosphere at different latitudes. In the mid-latitudes, there are often areas of low pressure, and the westerlies blow toward these areas, bringing weather systems with them. The polar easterlies, on the other hand, are winds that blow from the east to the west near the poles. They are caused by the cold, dense air sinking at the poles and flowing toward the equator. The polar easterlies meet the westerlies at around 60 degrees latitude, creating a boundary known as the polar front.

Answers
The researcher who conducted an investigation on a blood disease carried by birds found out that the organism is unicellular and has a nucleus, cell wall, and the ability to produce spores. Based on this information, the organism belongs to the Kingdom Fungi.
The kingdom Fungi consists of unicellular and multicellular organisms that lack chlorophyll and reproduce asexually and sexually by forming spores. They are heterotrophic organisms, which means they depend on other organisms for their food. Fungi cells have a cell wall made up of chitin, which provides strength and rigidity to the cell wall. The cytoplasm of the fungal cells contains many specialized organelles, including nuclei, ribosomes, mitochondria, and Golgi bodies that carry out various metabolic activities.
The researcher's findings suggest that the organism is a unicellular fungus with a nucleus, cell wall, and the ability to produce spores. Spores play a crucial role in the fungal life cycle, as they allow the organism to reproduce and spread to new habitats. These spores can be transported by wind, water, or other organisms to colonize new areas.
