Answer:
All the offspring will have genotype RrEe and will be right handed and have attached earlobes
Explanation:
Let the dominant allele for right hand trait be "R" and the recessive left hand trait allele is "r"
Allele for attached earlobes trait is "E" and free earlobes trait is "e"
Genotype of woman who is right handed and has free earlobes - RRee
Genotype of man who is left handed with attached ear lobe - rrEE
The genotype of offspring would be RrEe
All the offspring will have genotype RrEe and will be right handed and have attached earlobes

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

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.

Are the dark peppered moths and light peppered moths the same species? Why or why not?
Answer: No, the light-colored form of the peppered moth has different genes from the dark form.
Explanation: Pre-Industrial Revolution: light winged moths were camouflaged, dark winged moths stood out and were easy prey. How did numbers of each compare?
Industrial Revolution: smoke spewed into the atmosphere and coated the environment with soot. How did this affect numbers of each moth?
Post-Industrial Revolution: cleaner and greener environment. What has happened to the moths now?

Following a volcanic eruption, which event is usually the last one to be
observed?
A. Grasses begin to grow in soil with organic matter
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! ♡︎

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.
for my science class
Answer: the energy of the light is un changed as it passes from one media to another. when the visible light in air enters a medium such as glass, the velocity of light decreases to 75%of the velocity in air and in other materials the decrease can be even more substantial ..for air the velocity is 99.97% of the speed in vacuum.

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.

Which of the following statements about water policy is true?
a. Blackwater is cheaper and easier to process than greywater.
b. Desalination has no known negative impacts on the environment.
C. The water reclamation process is used to remove solids and impurities, but does not return
water to a potable state.
d. Water conservation efforts have been wholly ineffective.
e. The Safe Drinking Water Act limits the amount of pollution introduced into waterways.
Answer:
I believe it's C
Explanation:
Safe Drinking Water Act limits the amount of pollution introduced into waterways. Therefore, the correct statement is option E.
What is water policy?Water policy involves the set of laws, regulations, and strategies to govern the use, management, and distribution of water resources. Water policy takes decisions related to water supply, its quality, sanitation, etc.
The Safe Drinking Water Act is a federal law to protect the quality of public drinking water in United States. This act reduces the amount of pollutants added into waterways to protect human health. Environmental Protection Agency (EPA) is required by the law to set national drinking water standards for public water systems.
Blackwater is the wastewater from toilets and is expensive to process than greywater which is wastewater from sinks. However, desalination have also negative impacts on the environment.
Therefore, Safe Drinking Water Act is the water policy that limits the amount of pollution introduced into waterways.
