Answer: B. Modern bird species share many genetic similarities.
Explanation:
When organisms are said to have a common ancestor, it means that they share many genetic similarities but are not identical due to evolution and cross-breeding. For instance, siblings may have the same parents but they will not be genetically identical even though they have a lot of similar traits owning to their parents have different traits.
The same is true for birds. They share the genetic characteristics of their common ancestor but as time went on and evolution took place, they changed in some ways and so are no longer genetically identical.

Cell phones are widely used by people all over the world as a medium of communication. When a person makes a call from a cell phone, the cell phone emits electromagnetic waves that are intercepted by a nearby cell phone tower. The cell phone tower then connects the call to the phone of the person being called.
Which of the following processes enables a cell phone to receive communications from a cell phone tower?
A.
Electromagnetic waves diffract around the cell phone's antenna, which allows the waves to be detected by the internal circuits of the phone.
B.
Electromagnetic waves from the tower interfere with the radio waves emitted by the cell phone, producing electric currents in the internal circuits of the phone.
C.
Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.
D.
Electromagnetic waves from the tower are reflected by the cell phone, producing an electromagnetic field that is detected by the internal circuits of the phone.
R
Electromagnetic waves diffract around the cell phones antenna
Answer:
Electromagnetic waves from the tower produce an electric current in the cell phone's internal circuit when intercepted by the phone's antenna.

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.
How can the presence of one species in the same ecosystem assist another?A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.
The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Brighter feathers, however, give male birds a reproductive advantage and assist them attract female birds for mating. Because of this, populations of birds with brighter plumage continue to exist despite having a higher risk of being eaten by a predator.
Which of the following statements best describes why some birds have colorful feathers?They are used to entice prospective partners. Birds may recognize their own species by using colors and patterns. Birds can camouflage themselves against predators by using different colors. When courting, colors are utilized to draw attention (ie: courtship displays).

the blank determines which traits are adaptive during the process of natural selection
The environment determines which traits are adaptive during the process of natural selection.
What is natural selection?Natural selection is the process by which certain traits become more or less common in a population over time based on their effect on the survival and reproduction of the individuals that possess them. The individuals with traits that are better suited to their environment are more likely to survive and reproduce, passing those traits on to their offspring. Over time, this can lead to the evolution of species, as certain traits become more common in the population.
Natural selection is one of the main mechanisms of evolution and is often referred to as "survival of the fittest," although the term "fitness" in this context refers to how well an organism can survive and reproduce in its specific environment, rather than its physical strength or athleticism. Charles Darwin and Alfred Russel Wallace were the first to propose the theory of natural selection, it's based on observations of natural variation within populations, heritability of traits and the fact that more individuals are born than can survive to reproduce.

work from home will have a future impact on urban sprawl?
Answer:
Yes, working from home will have a future impact on urban sprawl. Working from home reduces the need for people to commute to their workplace, which in turn reduces the demand for housing in urban areas. This can lead to a decrease in urban sprawl, as fewer people are commuting to urban areas and thus fewer people are in need of housing. Additionally, with fewer people commuting to urban areas, there will be less traffic congestion, leading to a reduction in air pollution.

Mass wasting is movement of rock and soil down the hill. The rocky hillside slopes can be secured by slope reinforcement. if the slopes are not stabilized, landslide can cause damage.
What do you mean by mass wasting?Mass wasting is the movement of rock and soil down slope under the influence of gravity. Rock falls, slumps, and debris flows are all examples of mass wasting. Often lubricated by rainfall or agitated by seismic activity.
The most common types of mass wasting are slumps, rockslides, debris flows, and earthflow. Slumps are slow and short-distance downslope movements of semi-consolidated earth material on a curved or planar sliding surface.
The most destructive type of mass movement is a landslide, which occurs when rock and soil slide quickly down a steep slope. Some landslides may contain huge masses of rock, while others may contain only a small amount of rock and soil.

Thinking about the types of chemical
bonds, would you rather be in a relationship
that is more similar to an ionic bond or more
similar to a covalent bond? Explain your choice.
Ionic bonds are preferred as they are stronger than covalent bonds.
Why Ionic bonds are stronger than covalent bonds?Ionic bonds result in a stable composite when all of the electrons between the components are transferred. While two elements only share electrons to form a stable molecule in a covalent bond.
Electrostatic force and Van Der Waals force are the forces that keep ions together and covalently linked elements together, respectively.
Cations and anions are created as a result of the complete transfer of electrons in ionic connections. As a result, these ions are attracted to one another strongly by electrostatic forces.
The Van Der Waal's force that exists between two covalently bonded elements is weaker than the electrostatic force because covalently bonded components only share electrons.

In sediments and waterlogged soil, dissolved O2 concentrations are so low that the microorganisms living there must rely on other sources of oxygen for respiration. Some bacteria can extract the oxygen in sulfate ions, reducing the sulfur in them to hydrogen sulfide gas and giving the sediments or soil a distinctive rotten-egg odor. What is the oxidation number of sulfur in these compounds
Answer:
SO₄²⁻ (+6)
H₂S (-2)
Explanation:
To determine the oxidation number of sulfur in a compound, we need to consider that the sum of the oxidation numbers of the elements present is equal to the charge of the compound.
Some bacteria can extract the oxygen in sulfate ions...
SO₄²⁻
1 × ON(S) + 4 × ON(O) = 2-
1 × ON(S) + 4 × -2 = 2-
ON(S): +6
...reducing the sulfur in them to hydrogen sulfide gas...
H₂S
2 × ON(H) + 1 × ON(S) = 0
2 × +1 + 1 × ON(S) = 0
