A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?
Answer:
1.49 m/s; 5.367 × 10⁶ m/hr
Explanation:
Calculations: (This was my thought process, sorry)
386400 km ÷ 72 hr ≈ 5367
5367 × 1000 = 5.367 × 10⁶
5.367 × 10⁶ ÷ 3600 ≈ 1.49 m/s
About 5367 km/hr or 5.367 × 10⁶ m/hr or 2.592 × 10⁵ m/s

Purple flower color (P) is dominant over white flower color (p) in pea plants. A heterozygous pea plant with purple flowers is crossed with another heterozygous pea plant with purple flowers.
What will be the phenotypes, and probabilities of their offspring?
Question 11 options:
75% purple and 25% white
100% purple
100% white
50% purple and 50% white
Answer:
75% purple and 25% white
Explanation:
When a punnett square is drawn to predict the phenotypes of the pea plants offspring:
- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)
- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)

How are rivers made ?
Answer:
Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land - meandering - or going around objects such as hills or large rocks.
Explanation:
Hope this helps!
Answer:
A river is created when water moves from higher elevation to lower elevation. It usually goes downhill, and can join with other rivers. The river ends when it flows into an ocean.

• How is that code represented?
• What has the project revealed about the differences between humans and bananas?
• What questions does the Human Genome Project raise for you?
• What are outliers, and what is their value in understanding disease?
• How can a genetic mutation be advantageous?
• How is the knowledge of mutations being used to combat the HIV virus?
In this activity, students learn about the Human Genome Project. They do an interactive Web activity which simulates the process scientists use to determine the sequence of chromosomal DNA bases. Then they learn how two teams of scientists raced to decode the human genome. Next they explore a stretch of sequenced DNA on the Web to learn about the function of different sections of DNA code. They learn how knowledge of the human genome is being applied to medicine. They also learn about genetic variation among humans and between humans and other species. Finally, they assess what they have learned about the Human Genome Project by playing a game of Jeopardy.
Objectives
Learn about the purpose and work of the Human Genome Project
Describe the process of sequencing human DNA
Understand the functions of different stretches of code on a chromosome

Multiple Choice
Which of the following is typical of aerobic respiration?
decreases a plant’s weight
contains two stages, glycolysis and fermentation
produces methane as a byproduct
produces little energy
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".

Go Deep! Look at the Parent Chromsomes and Key pictured below. Would it be possible for these parents to have a daughter with Hemophilia?
Answer: No, the daughter will be a carrier only.
Explanation: Hemophilia is a sex-linked recessive disorder. The recessive gene is carried on the X chromossome. Males have only one X chromossome, while females have 2. So, for a male individual to have hemophilia, it only needs the recessive gene to be on the X chromossome. In a female, the disorder is expressed when both X chromossomes has the recessive gene.
In the Parent Chromossomes picture shown, the father's X chromossome doesn't have the gene for hemophilia and the mother is heterozygous for the trait, i.e., she carries the recessive gene.
A daughter will inherit an X chromossome from the father and an X chromossome from the mother.
In this family, the daughter will inherit the X with dominant gene H for the father and has a possibility of inheriting another dominant gene H or recessive gene h from the mother.
For the daughter to be hemophiliac, she has to inherit 2 recessive genes. Since in either case she won't, she only inherits 1 recessive gene, the daughter will be a carrier for the trait, not have the disease.
If mice with white coats are dominant to those with brown
coats, what is the genotype of a heterozygous mouse?
Explanation:

Explain the connection between nitrogen-fixing bacteria and the use of
fertilizer.
Answer:
They contain symbiotic rhizobia bacteria within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil
The water we drink now was the same water the dinosaurs drank. Discuss how the water cycle makes this statement accurate. Include different parts of the water cycle and what processes help move the water through each part.
Answer:
This is what I got for the answer, I do not know if this is right though.
Yes. The water on our Earth today is the same water that’s been here for nearly 5 billion years. Only a tiny bit of it has escaped out into space. As far as we know, new water hasn’t formed either.
That means there’s a very high chance the water in your glass is what thirsty dinosaurs were gulping about 65 million years ago.
It’s possible that you could drink the same water as a stegosaurus or a T-Rex because of the way water circulates around our planet. A dinosaur, you, and I are actually part of this water cycle, too.
As water on the surface of lakes, oceans, and rivers warms up, it travels into the sky as very tiny droplets, or vapor. When the water vapor gets colder, it turns back to liquid to help form clouds.
When the liquid gets so heavy it can’t stay in the atmosphere anymore, it falls, or “precipitates,” as rain, snow, sleet, hail, or, my favorite, graupel. Once the precipitation reaches the ground or lands in lakes, oceans, and rivers, the cycle continues.
You, a dinosaur, and I drink water, and eat foods that contain this water, too. It’s so refreshing to lap it up from my bowl. We get rid of some water as fluids or gases, such as the ones we let out when we breathe.investigates the water beneath Earth’s surface. He’s a geologist with Washington State University’s School of the Environment.
He said water also moves in ways we don’t always think about. Scientists have found water trapped in minerals deep within the Earth’s mantle and crust, he explained. This water is even older than dinosaurs. It doesn’t look like liquid water that’s in your glass, but it still made of the same stuff.
“We’ve realized there is a lot of water down there,” Keller said. “There’s as much water chemically speaking, more or less, as there is in the oceans. It’s just in a different form.”
Another place we find water from dinosaur days is in organic matter. When the dinosaurs died, their bodies broke down to become part of the Earth. Over time, some of this organic matter became shale, coal, and oil we use for fuel.
The water dinosaurs drank is in more than just the water we drink, minerals, and organic matter. It’s also what we use to shower, cook, and water plants for food.
Right now, Keller is visiting with fellow scientists at the Global Institute for Water Security in Saskatchewan, Canada. They are curious about how we’ll take care of our water for the future.
“Life as we know it – every cell in every plant and animal — is mostly water. To say it requires water is an understatement,” Keller said.
The water in your glass may be the same water dinosaurs drank, but it’s also the same water that’s going to keep life on our planet in the years to come.
Explain how the nervous system works within your body as you go throughout the day. From waking, eating, going to school, extracurricular activities, and finally bed; state how the different parts of the nervous system work together to complete these tasks.”
Answer:
when you wake up the nervous system remembers to get dressed for school as well as eating the brain remembers to pick up a fork or spoon to eat, going to school the brain will remember what time the bus will come and when to go to the bus, doing extracurricular activities the brain will tell your arm to throw a football or kick a soccer ball, when going to bed the nervous system will tell the nerves in your arms to pull the blanket on top of you and to turn the light off.

If you are studying a gene within DNA and find out that guanine makes up 41% of it, how much is Adenine?
There are four bases found in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine forms a base pair with thymine, and cytosine forms a base pair with guanine. There is a one-to-one relationship in these base pairings (Chargaff’s rule), which means that if you know the percentage of any one of them within a given DNA sample, you can calculate the percentages of the other three. In this case, you're given the percentage of guanine, and you want to find out the percentage of adenine.
Since guanine base-pairs with cytosine and since there must be as much cytosine as there is guanine, 41% of the bases in this gene are cytosine as well. That means that adenine and thymine together make up the remaining 18% (100% − 41% G − 41% C) of the base pairs. If there must be an equivalence in the number of thymine and adenine bases per Chargaff's rule, then half of the remaining base pairs must comprise adenine and the other half comprise thymine. Half of 18% is 9%.
Thus, adenine makes up 9% of the bases in this gene.
