Answer:
one with the fewest number of genetic differences in the nucleotide sequence.
Explanation:
A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.

Individual "A" produces 10 offspring, 8 of whom survive to adulthood. Individual "B" (a member of the same population) produces 15 offspring, 7 which survive to adulthood. Based on the concept of natural selection, individual "A" has the higher fitness.a) trueb) false
In natural selection when more offspring is survived is a sign of higher fitness of the particular population, hence given statement is true.
What is natural selection?Most qualities are inherited, there are more children generated than can survive, and offspring with more advantageous features will survive and have more offspring than those with less advantageous traits leading to the inevitable process of natural selection.
Since there are only so many resources available, more creatures are born than can live those who are better at obtaining food.
Mating or evading predators will have a higher chance of thriving, procreating, and passing on their DNA.
Therefore an individual in the population has offspring to survive more in number.

Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible? (1 point)
O Metals have low electronegativity, so they are conductive because they pass charges easily.
OTwo metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
O The bonds can shift because valence electrons are held loosely and move freely.
O An attraction between a positive charge and a negative charge is created.
The correct answer is; Metals have low electronegativity, so they are conductive because they pass charges easily.
Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.
A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.
This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.

E. intoxication caused by a focal C. tetani infection.
Answer:
The correct answer is E. intoxication caused by a focal C. tetani infection.
Explanation:
Clostridium tetani bacteria are found in the soil, in the feces and in the mouths of animals. The disease is acquired when wounds become infected by the bacteria. The spores become active and spread throughout the body producing a poison called tetanus toxin. This toxin blocks the nerve signals from the spinal cord to the muscles and can cause generalized severe muscle spasms (lockjaw) exacerbated by external stimuli or muscle spasms in areas adjacent to the wound.

what are the structural adaptation of whales and dolphins (compare them please)
Answer:
Whales and dolphins are mammals and have lungs instead of gills for breathing. They have blowholes at the tops of their heads that function like nostrils; they need to put their heads above water every so often to breathe. Both dolphins and whales have hair instead of scales, another quality that is specific to mammals. The animals have live births instead of laying eggs, and baby dolphins and whales nurse from their mothers. Whale and dolphin births take place near the surface of the water, so the young animals can easily take their first breath.
Both whales and dolphins rely on the sounds they make for survival, even though the sounds are utilized differently by each animal. For instance, whales make high-pitched groans and whistles to communicate with one another to warn against danger or navigate during migration
Answer:
COMPARISON AND CONTRAST OF WHALES AND DOLPHINS
Both dolphins and whales belong to the cetacean family and are marine animals that reside in the ocean. Some scientists even assert that dolphins are a type of whale, as the two animals have a number of shared characteristics. However, there are distinct differences between whales and dolphins as well that will teach you more about the physical appearance of these marine creatures and how they survive in their environment.
If the percent concentration is greater in the fluid outside a cell than inside a cell, how will the water
flow?
This means the solution would be___________
Which tube(s) did this happen to?
Answer:
The water will flow from the inside of the cell to the fluid outside the cell. This means that the solution would be hypertonic.
It will happen to the tubes that have a higher concentration of solutes in the fluid outside cells than inside the cells.
Explanation:
When a cell is in a hypotonic solution, it means that the concentration of solute in the solution is higher than the one in the cell. As a natural reaction, the cell tries to balance this difference. To do this, the water that is inside the cell flows to the outside. As a result, the concentration between the inside and the outside of the cell becomes equal or more equitable. Besides, the cell shrinks due to the loss of water.
