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

state two functions of the onjective lens on a microscope
Answer:
please give me brainlist and follow
Explanation:
In microscopy, the objective lenses are the optical elements closest to the specimen. The objective lens gathers light from the specimen, which is focused to produce the real image that is seen on the ocular lens. Objective lenses are the most complex part of the microscope due to their multi-element design.

What is Water Pollution?Water Pollution is the contamination of the water bodies by human activities causing water unusable for drinking, cooking, etc. It contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and making toxic to humans or the environment.
Types of Water Pollution
1. Groundwater pollution
2. Surface water Pollution
3. Ocean water pollution
4. Point source pollution
5. Non-point source
It is mainly caused by
1. Industrial waste
2. Oils leak and spills
3. Global warming
4. Agriculture
It can be controlled by not using chemical fertilizers in the agricultural field, use the minimum amount of detergents or bleach near water bodies.
So, there are three methods of point pollution control are
1. To use less toxic or non-toxic chemicals
2. To use public transport and avoid personal vehicle

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.

which type of traits are responsible for evolution?
Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

D. Trees begin to grow in thick, rich soil.
Answer:
Hello There!!

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!
