Organism (a) is a common ancestor of all chordates.
Descendants of organism (d) have limbs with digits. birds and ray-finned fishes have a notochord and jaws.
rays and frogs have vertebrae. organism (c) is a common ancestor of lampreys and lungfishes?
The correct options are;
Mammals and turtles are more closely related than are lungfishes and sharks.
Descendants of organism (d) have legs.
Rays and frogs have a vertebral column.
-Birds and ray-finned fishes have a notochord and jaws
Explanation:
This is because phylogenetic tree is a branching diagram that entails different evolutionary relationships that occur between organisms or biological species having common decent or ancestors and showing similar and differences in their genetic characteristics or traits. It shows how species evolved from their ancestors.

Which of the following is not one of Mendel's Laws?
a) Law of Conservation of Mass
b) Law of Segregation
c) Law of Dominance
d) Law of Independent Assortment
Answers
Answer:
A
Explanation:
Law of conservation of mass was discovered by Lavoisier
Law of Conservation of Mass is not one of Mendel's Laws. Therefore, the correct option is A.
What are Mendel's Laws?Gregor Mendel's research with pea plants in the 19th century led him to reveal three fundamental laws of inheritance, known as Mendel's laws. There are three laws:
1. Law of Segregation: Each individual has two alleles for each trait, and this law indicates that these alleles separate (separate) during the development of gametes, or reproductive cells. This indicates that only one allele per trait is present in each gamete.
2. According to the law of independent assortment, the inheritance of one trait is independent of the inheritance of another. In other words, the segregation of alleles for one trait is independent of the segregation of alleles for the other trait.
3. The law of dominance states that when two different alleles are present in an individual, the dominant allele will dominate the recessive allele in terms of expression. Only when both alleles are recessive will the recessive allele be expressed.
Therefore, the correct option is A.

Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful. Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?
this is for biology test pleasee someone help
Answers
Answer: Same Genus but different species
Explanation: took the test and came back
The statement which correctly describes the relationship between the two populations of tree frogs is same genus but different species.
What are the characteristics of genus?A genus is a class or group of something. In biology, it's a taxonomic group covering more than one species. This is a term used by biologists to classify more than one species under a larger umbrella.
A species is defined as a group of organisms made up of similar individuals capable of interbreeding or exchanging genes. Genus: A genus is a taxonomic classification that includes closely related species.
Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family.

Place a single word into each sentence to make it correct, then place each sentence into a logical paragraph order. Blood leaving the chambers Waste products will then be ____________ by the tubules.
Answers
Answer:
Blood goes to lungs for the removal of carbondioxide and loading of oxygen whereas kidney filters the blood and sent the waste to urinary bladder.
Explanation:
Blood leaving the chambers and this blood goes to the lungs through pulmonary artery that carries deoxygenated blood. In the lungs, carbondioxide gas is removed from this blood and oxygen is added to the blood. This oxygenated blood goes to the heart through pulmonary vein and the heart pump this blood to all parts of the body. Waste products that is produced during metabolism in the liver will then be transported to the kidney for filtration by the tubules. After filtration the waste products are sent to the urinary bladder through ureters.

What determines the direction of gas movement?
Answers
Answer: The direction of gas movement is determined by partial pressure differences. 2) At the arterial end of the pulmonary capillaries, O2 diffuses from the alveoli into the blood, while CO2 diffuses from the blood into the alveoli.
Explanation:
→ Oxygen and carbon dioxide diffuse across a respiratory membrane.
Factors determining gas movement:
The concentration gradient of the gases and the partial pressure of the gases.The differences in concentration on either side of the cell membrane.→ In diffusion of gases:
The amount of surface area available for diffusion.The distance the gas particles must travel.The higher the concentration gradient across the gas-exchanging surface, the faster the rate of diffusion across it.Learn more:

2. What does the atomic model teach you about the ability of scientists to
study things that cannot be directly observed?
Answers
Answer:
The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.

freely moving electrons, while Van der Waals forces cause an
attraction between nonpolar molecules.
B. Covalent bonds form when there is an attraction between
nonpolar molecules, while Van der Waals forces cause two atoms

C. Covalent bonds occur when two atoms share valence electrons,
while Van der Waals forces cause an attraction between positive
Answers
Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).
Answer:
Covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between nonpolar molecules.
