In the Galapagos Islands, there were many species of tortoises, woodpeckers and other animals. Why were the animals like the tortoises so different in appearances, when they lived on neighbor islands?
Answer:
The animals were different because there were things the animals need to adapt to in the Galapagos that may have changed their appearance. for example a bird may have a different shaped beak because they started to evolve so they could eat foods that were available to them on the island

B. Lichens begin to cover bare rock.
C. Mosses begin to grow in thin, rocky soil.
D. Trees begin to grow in thick, rich soil.
Answer:
Hello There!!
Explanation:
The answer is=>A. Grasses begin to grow in soil with organic matter.
hope this helps, have a great day!!
~Pinky~
Answer: I do know the answer, I always use the Study Guide, which is incredibly helpful, I will share both my notes, and answer, which is D. Trees begin to grow in thick, rich soil.
Explanation: After a volcanic eruption, a process known as a Ecological Succession happens. Resulting in, lichens, which is the first living species to grow on the rocks. Afterwards, mosses and small annual plants are the second species, these species begin to grow in soil made by the lichens, since after the eruption the lichens release acid that helps break the rock into soil, then the mosses and annual plants reproduce by the help of the wind, and use the soil formed by the previous species. Furthermore, grasses and other long living plants begin to grow in the richer soil. Then, grasses, shrubs, and intolerance trees, such as pine form. Until, the last observed, which is shade-tolerant trees, such as oak and hickory! Have a good day, you’re welcome. P.s. Provided a picture from my source! And the Quiz as I have the same one, if I can! ♡︎

C. It shows the Sun at the center of the solar system.
D. It shows the orbits of the planets as circular.
Answer: Orbital Motion Unit Test
1. A line between a planet and the sun sweeps out two equal areas at different places as it moves along its orbit. Which factor remains constant as this happens?
Answer: The time required to sweep out the areas.
2. Which are features of Copernicus's model of the solar system? Select three correct answers.
Answers: The sun is at the center.
The planets move in perfect circles.
The stars are fixed to an outer sphere.
3. An asteroid approaches Jupiter and is slung around around into a new trajectory across the solar system. Which of the following are possible? Select three correct answers.
Answers: The asteroid spirals into the sun.
The asteroid continues out of the solar system.
The asteroid enters a stable elliptical orbit around the Sun.
4. A satellite orbiting the Earth at an orbital radius r has a velocity v. Which represents the velocity if the satellite is moved to an orbital radius of 5r?
Answer: 1/√5 v
5. Which did Kepler notice about planetary motion that caused him to propose Kepler's first law of orbital motion?
Answer: The distance to the Sun varies.
6. Which statements about the geocentric model are false? Select two correct answers?
Answers: It explains why Mars appears to move backward for a few months approximately every two years.
It shows the Sun at the center of the solar system.
7. The mass of an object doubles. What happens to the gravitational force between it and another object whose mass stays the same, assuming they remain the same distance apart?
Answer: The amount of the gravitational force doubles.
8. What shape is the moon's orbit around Earth?
Answer: An ellipse that is almost circular.
9. Which of the following statements about Newton's theory of universal gravitation are true? Select the three correct answers?
Answers: The theory applies to all objects in the universe.
Gravitational force increases as the distance between objects decreases.
Gravitational force increases as the mass of objects increases.
10. Which form of Kepler's third law can you use to relate the period T and radius r of a planet in our solar system as long as the unit year is used for the period and astronomical unit is used for the radius?
Answer: T²= r³
11. Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the Sun?
Answer: The greater the distance, the slower the orbital velocity
12: For a moon orbiting its planet, rp is the shortest distance between the moon and its planet and ra is the longest distance between the moon and its planet. What is a moon's orbital eccentricity if rp is equal to 0.27ra?
Answer: 0.57
Explanation:
Sorry I didn't do the short answer questions but these are all the correct answers to the science unit test.
The statements about the geocentric model that are false include:
B. It explains why Mars appears to move backward for a few months approximately every two years.C. It shows the Sun at the center of the solar system.The geometric model also refers to geocentrism. It refers to a theory of the solar system that's based on the fact that the Earth is at the center. It's the description of the universe with the Earth at the center.
Therefore, it shows the Earth at the center of the solar system and it shows that the orbits of the planets as circular. It doesn't explain why Mars appears to move backward for a few months approximately every two years. It also doesn't show that the Sun is at the center of the solar system.
In conclusion, the correct options are B and C.

After fertilisation of plants
occurs between the male gamete and the egg cell, the zygote produced undergoes mitosis forming two cells. explain.
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). The zygote stage is followed by cleavage when a cell gets subdivided into further smaller cells.
Explanation:
Fertilization is defined as the fusion of the male gamete (sperm) and the female gamete (egg cell) in plants that develops into a zygote. After fertilization, a series of events occurs in the zygote to develop into a seed.
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). The zygote stage is followed by cleavage when a cell gets subdivided into further smaller cells.
Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the
male minnows all had a moderate number of spots
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were
better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female
minnows in this pond preferred to mate with males that had the most spots,
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
Answer:
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.
