Don has a mutation in his genes. Neither of his parents have Don's mutation. Don's mutation is present in all of his cells. Where did this mutation first occur?
a) in any of don's cells. the mutation then spread
b) we cannot know. more information needed
c) in the sperm or egg cells of his parents
d) in don's sperm cells. the mutation then spread
Neither of his parents have Don's mutation. Don's mutation is present in all of his cells. Both of the parents may have had the recessive gene and passed it on to the child, don.
What are the 4 types of mutation?Germline mutations occur in gametes. Somatic modification occur in other body .Chromosomal modification are changeovers that alter chromosome structure.Point mutations Frameshift mutationsThus, option "C" is correct, in the sperm or egg cells of his parents.

Deserts typically have average daytime temperatures of around 100°F, while the average daytime temperature in tropical
rain forests is around 85°F. However, the average monthly temperatures in the desert are lower than the average
monthly temperatures in a rain forest. Explain the reason for this difference.
Answer:e
Explanation:it its different because when a desert ends up cooling down than you have to deal with cold temperatures sorry if i spelled that wrong also rainforest keep that heat in because of the trees so the desert doesn"t have any trees not enough to keep the heat in so the heat gets out and the temperatures end up cooling down hence why the rainforest has a higher temp.

Do you think an international orbiting space station is a good idea? Why or why not?
Answer:
Yes it is (we already have one)
An international orbiting space station would be a great idea! We could use the space station as a refueling point for passing spaceships. This could helps us achieve things such as space exploration, mars/moon colony, or even contact with other unearthly organisms. This could also allow us to conduct space research.
No it isn't
An international orbiting space station is a horrible idea! The first thing to think about is the money. This would put the entire area in stasis as we try to raise money for the space station. We also need contact with the humans/robots in space! Building a space station would confuse other nations as to what we plan to do with said space station. This could cause a war of some sort.
Write an argument for or against the following statement. The energy humans use in cars originally came from the Sun.
Answer in paragraph form using 5-7 complete sentences.
NO LINKS!!!!!!
do the energy humans use in their cars actually originate from the sun? they do! most products like oil, gas, and coal actually come from the sun. the reason why i say this is because all those things are natural which means they came from photosynthesis. according to the site (Where Does the Energy in Fossil Fuels Come From? http://techalive.mtu.edu) "So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!"
Explanation:
True. All of the energy in coal, gas, and oil was first stored by the sun through photosynthesis. Hence, in a certain sense, solar power is used by gasoline-powered vehicles, coal-fired power plants, and residences heated with natural gas.
What is Energy?In order to accomplish work and to produce heat and light, energy must be transferred to the a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
Energy is the ability to do tasks. It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc. Moreover, there is heat and work, which is energy being transferred from one object to another. Energy is always assigned based on its nature once it has been transmitted. Hence, heat transmitted may manifest as thermal energy while work performed may result in mechanical energy.
Thus, all of the energy in coal, gas, and oil was first stored by the sun through photosynthesis. Hence, in a certain sense, solar power is used by gasoline-powered vehicles, coal-fired power plants, and residences heated with natural gas.

Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed.
this is for the Absorption and Radiation by Land and Water
Answer:
What I recommend doing to writing the perfect lab report is to think of it as a story. Begin stating the facts and such things. Then include your preliminary observations. End it with describing the results and explining why they are important. If you want a good grade, I recommend also tying it all back to the lesson your teacher was teaching you to begin with. You dont have to be a genius to write an amazing report, just state things from your observations and the lesson.

Hello.
Your answer is: Helping people is one of your passions, so you wake up early and volunteer two Saturdays a month at a local soup kitchen.
Explanation:
Intrinsic motivation is an act of doing something without any kind of external award. Helping people and not expecting anything back is considered Intrisic motivation, thus giving us the answer above.
Helping people is one of your passions, so you wake up early and volunteer two Saturdays a month at a local soup kitchen is an example of intrinsic motivation. The correct option is B.
One of your loves is helping people, so you get up early to assist at a neighbourhood soup kitchen twice a month.
In this instance, the drive to volunteer is an innate desire to assist others. It is motivated by a sense of purpose, personal values, and interests.
Without any outside benefits or incentives affecting their choice, the person gets fulfilment and joy in making a contribution to a cause they actually care about.
This exemplifies intrinsic motivation, which is fueled by internal forces rather than rewards or pressures from the outside world.
Thus, the correct option is B.

describe how the bones, muscles, and sensory organs all work together.
The bones, muscles, and sensory organs are grouped to all work together around a common goal: movement.
How the bones, muscles, and sensory organs work together?Sensory organs capture the information, the bones form the skeleton and the muscles that work harmoniously are inserted into the bones through the tendons, allowing the movement of the joints.
They all work together to support the body, keep it in shape and allow it to perform coordinated movements, thanks to the coordination exerted by the nervous system.
Therefore, we can conclude that the bones, muscles, and sensory organs are grouped to all work together around a common goal: movement.

If a person has brown hair, what genotypes might they have?
Answer:
Genotype is the genetic makeup of an individual. Phenotype is the physical appearance of brown hair.
Hello, I Am BrotherEye
Answer:
Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.
Explanation:
Your genotype codes for your phenotype — the trait we can actually see. For example, if the blue-eyed parent passed down a blue allele, and the brown-eyed parent passed down a brown allele, the child's genotype will be blue-brown, and his or her phenotype will be brown.
