what caused seed abundance to decrease from 1975 to 1978
Answer:
The finch population decreased.
Explanation:
When finches eat seeds, some pieces fall onto the ground which grow up to have more seeds. The seeds that survived were too big for a finches tiny beak. Without this cycle in place, seeds had no way to reproduce.
The population of finch gradually decrease from 1975 to 1978 that caused the seed abundance to decrease too.
What is the reason for decrease of seed abundance in 1975 to 1978?During 1975 to 1978, there were no small seeds present for the feeding of finches, this cause the gradual decrease in the number of small beak finches.
Many small beak finches died during this time.
This affects the seed production too, because when birds eat seeds they help them to disperse in many other areas, which increase pollination and increase seed production.
Thus, when the population of finches decrease, the seeds production also decreases during 1975 to 1978.

what are the 4 different bases in dna and how do they pair?
Answer:
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Write a short answer below describing each energy transformation in the diagram which is located
above. For example describe how photosynthesis captures energy in and releases energy out (include
what form of energy). Next describe how cellular respiration captures in and releases energy out (inlcude
in what form.)
Answer:
Photosynthesis: the plant takes in energy from the sun, converts it into glucose (photosynthesis), and releases energy as Oxygen Gas (O2)
Cellular Respiration: Food is taken in by the organism and process in the digestive system going through aerobic processes and is released by Carbon Dioxide (CO2).
Explanation:
You need Carbon Dioxide to start Photosynthesis including water and sunlight, the process inside the plant undergoes the Calvin Cycle, Carbon Fixation, and Reduction. Plants can also go into fermentation engulfing alcohol or lactic acid (when your muscles are sore after you work out). Oxygen gas is released after carbon fixation turning into pyruvate and is no longer needed to continue the process.
You need Oxygen Gas to start Cellular Respiration. Inside the cells, Glycolysis, Pyruvate Oxidation, the Krebs Cycle, and Oxidative Phosphorylation occur. After the reaction, Carbon Dioxide (CO2) is released from the cells as heat.

What does it mean to impregnate xylem a cell wall?
Answer:
The walls of xylem cells are lignified (strengthened with a substance called lignin). This allows the xylem to withstand pressure changes as water moves through the plant.
Explanation:
The xylem transports water and minerals from the roots up the plant stem and into the leaves.
In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.
Vessels:
Lose their end walls so the xylem forms a continuous, hollow tube. Become strengthened by a chemical called lignin. The cells are no longer alive. Lignin gives strength and support to the plant. We call lignified cells wood. Transport in the xylem is a physical process. It does not require energy.

Answer:
artificial selection/selective breeding
Explanation:
The illustration is an example of artificial selection.
By definition, artificial selection is the deliberate perpetuation of some traits in living organisms simply because the traits are desirable. The organisms are selected because of the traits and allowed to breed either naturally or otherwise in order to ensure that these traits appear or are even consolidated in the offspring of the breeding.
The offspring from selective breeding are expected to combine the desirable traits of the two parents and thus, appear better than each of the parents.
Answer:
artifical breeding

A scientist studying the Milky Way galaxy notices a bright light in the sky. What information would she need to prove that the object is a comet and not a star?
Answer:
She would need lots of info, but some examples are,
A. Whether or not the subject is moving
B. Whether or not the subject disappears after a set amount of time
C. Whether or not the subject is near or far, and if it changes in size.
Explanation:
The correct answer is I and II.
A comet is made up of ice, dust, and small rocks or particles. They revolve around the sun and can be considered a member of the solar system. When they pass close to the sun they get heated due to solar radiation and start to release gases that are initially in the condensed phase. This release of gases produces a glowing tail behind the comet. When warmed up they produce a bright coma which can be of the order of several times the diameter of Earth.
