Answer: Firstly it should be noted that, the chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. On this wise, their genomes would be more similar to each other than are the genomes of the five tree finch species. Secondly, they should be limited to the six islands that most recently emerged from the sea.
Thirdly, they should share fewer anatomical homologies with each other than they have shared with the tree finches.
Fourtly, their genomes should be more similar to each other than are the genomes of the five tree finch species.

please help me. I been stuck on this question for a long time :(
Answer:
Explanation:
1. Climate change is caused by changes in the earth's atmosphere in the amounts of greenhouse gases released into the air. Some scientists believe that 100% of global warming is due to humans. The largest contribution comes from burning fossil fuels because it releases carbon dioxide gas to the air, which is done by humans. Other factors that contribute to climate change include:
>Deforestation- clearing out trees affects wildlife, ecosystems, whether patterns. Forests cover 30% of the lands mass and clearing them leaves many animals without homes.
>Waste from factories- they release tonnes of toxic fumes into the air.
> Agriculture and farming- this is a surprising contributing factor to global warming. Animals produce a greenhouse gas called methane and when livestock are grazed at a large scale, the amount of methane produced is a big contributor to global warming.
Some fertilizers release nitrous oxide, which is another greenhouse gas.
2. The effects of global warming include:
>Melting glaciers- this leaves many animals without homes and it also causes a rise in sea levels which causes flooding. (that's 3 effects)
>Worsening droughts- this leaves many humans to die as they have no food or water.
>Increasing tornadoes

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.

2. Which of the following statements is true of persuasive messages?
A. People tune out repetitious messages, so they quickly lose effectiveness.
B. Messages presenting a one-sided argument tend to be more effective than "he said; she said" messages.
C. Messages that offer a remedy for a person's fears tend to be effective.
D. An effective message will reach all audiences, regardless of background.
Answer:
C. Messages that offer a remedy for a person's fears tend to be effective.
Explanation:
The manner in which the message is presented. Presenting two sides of an argument makes the message seem more believable and persuasive than presenting just one side. Such an approach gives the message a sense of being impartial and factual. *Presenting a fear factor also may persuade people. For example, ads for different kinds of medicines present the dangers lurking around us as they offer a remedy.
Repetition. Repeated exposure to stimuli—like ads—is more likely to have favorable effects on attitudes than infrequent exposure. That’s why companies spend lots of money making sure their ads run again and again and why they have their logos and messages on race cars, buses, and billboards. The more often you see or hear a message, the more likely you are to have a positive attitude toward it.
Messages that offer a remedy for a person's fears tend to be effective is true for persuasive message. Therefore, option (C) is correct.
What is a persuasive message?To persuade someone means to move them emotionally or to motivate them to act in a certain way by presenting them with arguments that convince them to accept your viewpoint or act in the way you want them to. A persuasive message can be either spoken or written and is a form of communication that persuades the reader or listener to behave or act in a particular way.
The first step in convincing someone is to motivate them. If persuasion is a process, and the action of your audience (such as purchasing a product or service) is the goal, then motivating them to accept an argument or a series of positions leading to the decision that you want them to adopt is one way to help achieve that goal. If you want them to buy a product or service, for example, this would be an action.

Somatosensory cortex
Answer:
I think, you answer is. somatosensory cortex.Explanation:
Hope it helps you.....Thank you..Somatosensory cortex area of the brain receives information collected from mechanoreceptors. Option D is correct.
The somatosensory cortex is a region of the brain that receives information collected from mechanoreceptors. Mechanoreceptors are sensory receptors that respond to mechanical stimuli, such as touch, pressure, and vibration. The somatosensory cortex is located in the parietal lobe of the brain, and it is divided into two parts: the primary somatosensory cortex and the secondary somatosensory cortex.
The primary somatosensory cortex receives information from the skin, muscles, and joints. The secondary somatosensory cortex integrates this information and allows us to perceive the location, intensity, and quality of touch. The pons is a region of the brainstem that is involved in the coordination of movement and the regulation of sleep. The olfactory lobe is a region of the brain that is involved in the sense of smell. The medulla is a region of the brainstem that is involved in the control of breathing, heart rate, and blood pressure. Option D is correct.

What happens when volcanoes release greenhouse gases into the atmosphere?
Answer:
a. the climate gets warmer...
Explanation:
When volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.
What do you mean by the Greenhouse effect?The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere.
Greenhouse gases like carbon dioxide, Methane, and Nitrous oxide allow the solar radiations to enter but prevent the escape of heat radiations of longer wavelength.
Due to this, the gradual and continuous increase in the average temperature of the earth's surface occurs, a phenomenon known as global warming.
Therefore, when volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.

PLEASE ANSWER QUICKLY Which statement about cell theory is INCORRECT? New cells are spontaneously created from existing cells. All organisms are composed of one or more cells. Cells are the basic unit of life and structure. New cells are created from existing cells.
Answer:
New cells are spontaneously created from existing cells
Explanation:
In the 1830's, three scientists namely: Matthias Schleiden (a botanist), Theodor Schwann (a zoologist) and Rudolf Virchow proposed the Unified cell theory. In this theory, three parts were universally accepted and they are as follows:
1) Cells are the fundamental and basic unit of all life and structure.
2) All living organisms are made up of one or more of these cells.
3) New cells arise from already pre-existing cells.
These three parts are the widely accepted parts of the cell theory. Although, it was once believed that new cells arose from inorganic matter. This theory, called spontaneous generation or abiogenesis was later disapproved.
Therefore, the statement that, "new cells are spontaneously created from existing cells" is not a part of the CELL THEORY.

How are the molecules in photosynthesis and cellular respiration similar? Please include descriptions of the molecules
Answer:
They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
They exhibit the same responses, but they do so in reverse. Carbon dioxide and water are converted during photosynthesis into glucose and oxygen. Carbon dioxide and water are produced during respiration in exchange for glucose and oxygen.
What similarity in photosynthesis and cellular respiration?Energy transformations from one form to another are a part of both respiration and photosynthesis through a sequence of metabolic reactions.
The reactions that are carried out by both processes—which both use and produce ATP—are carried out on membranes and are managed by enzymes.
Light energy is converted by photosynthesis into chemical energy that is stored in glucose, which is then released by cellular respiration to create ATP, the life-sustaining compound.
Therefore, They are similar because they both produce energy, but in two different forms.

Which observation led Mendel to the idea that traits were controlled by more than a single factor? Crossing two purple-flowered pea plants always resulted in a purple-flowered pea plant. Crossing two white-flowered pea plants always resulted in a white-flowered pea plant. A trait that was not seen in the first generation may later reappear in the second generation. A trait that was not seen in the first generation was completely gone and never reappeared.
Answer:
The answer is option C.
Explanation:
Genetic traits are expressed by dominant and recessive genes, which show up in the phenotype according to their presence on the chromosomes.
Observing a trait that was not present in the previous generations suggests that this trait is recessive and did not have the chance to appear in the other generations before. This idea has led Mendel to the idea that traits were not controlled by only a single factor. So the answer is C.
