On the Galapagos Islands, in the Pacific Ocean, live over a dozen species of small birds that are the same except for their beaks. Each species beak is a different size and shape. Birds with small, narrow beals ate either small seeds or insects. Birds with large beaks ate larger seeds. Based on the information in the passage, explain why there are two different beak sizes on the island. What will most likely happen to the finch population if the large seed plant becomes extinct.
Why would this happen? How can adaptations and natural selection help explain the reasoning for population changes in finches?
Answers
Answer:If the large seed plant becomes extinct the finches with larger beaks will probably die out thus reducing the finch population
2)This will happen as their source of food is gone and thus leaving them to either feed on what there not used to or die
3)im not too sure of this but this is what i think; In Darwin's finches, those that have short beaks turned out to be an adaptation that made them more suited into poking holes in the ground and feed on grubs. Also the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

Answers
Answer:
Explanation:
Energy is absorbed to break bonds. Bond-breaking is an endothermic process. ... Bond-making is an exothermic process. if a reaction is endothermic or exthermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.
In all types of chemical reactions, bonds are broken and reassembled to form new products.
In exothermic, endothermic and all chemical reactions it takes energy to break existing bonds and energy is released when the new bonds are formed.What is a chemical reactions?A chemical reaction is a process in which one or more substances, the reactant are converted into one or more different substances, the product.Substance are either chemical elements or compounds.To know more about chemical reaction here

Do substances that dissolve in water pass through the plasma membrane
Answers
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane

Hello, Connexus friends hopes this helps this is all the review questions + they correct cuz I got 10 out of 10 let me know if you need help!
The first piece of evidence Hubble has discovered is that galaxies are moving away from each other. The second piece of evidence is that the universal temperature has increased dramatically. The third piece of evidence is that cosmic microwave background radiation is found uniformly throughout the universe.
We can arrive at this answer because:
The Big Bang theory claims that the universe and all of its elements arose from a strong explosion.Although it is a debated and questioned theory, Edwin Hubble found evidence that proves its veracity and is accepted by many scientists.Within this evidence, Hubble claims that the universal temperature continues to increase drastically, which causes the galaxies to move away.The Big Bang was generated from a large amount of pressure and temperature, which caused the universe to expand, so Hubble's evidence may be true.Furthermore, Hubble claims that cosmic microwave background radiation is found uniformly throughout the universe and that this is a trace of the Big Bang.

How do you think the scientific method can be used the rate of photosynthesis?
Answers
1) learn that the rate of photosynthesis is influenced by environmental factors that can be quantified
2) understand the equation of photosynthesis and how the structure of a leaf allows for the required gas exchange to occur through the stomata
3) properly design an experiment with one variable, analyze results and report findings to the class
Students will use higher order thinking skills throughout this activity. They will need to use critical thinking to design the experiment and analyze the collected data. They will improve their observing, questioning and communicating skills. The students will need to determine if the question they have chosen to test, is indeed testable. The teacher will guide students to problem solve as they design and modify the experiment to insure only one independent variable is being tested during the experiment.
The students will learn specific concepts during the activity. The students will learn that:
1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis.
2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose. This carbon dioxide will be supplied by sodium bicarbonate dissolved in the water with the plant leaf disks
3) the stomata opening is controlled by the guard cells and that water, carbon dioxide and oxygen all pass through the stoma openings
4) food production for animals and humans on earth is dependent on plants. By increasing the use of carbon dioxide by plants, it may help slow global climate change. In turn, climate change (warmer in some regions, cooler in other regions) may affect various species of plants differently.
