In sheep white wool (W) is dominant over black wool (w). What genotypic ratio is expected from a cross between a heterozygous sheep with white wool, and a sheep with black wool?
Answer:
W w
w Ww ww
w Ww ww
Explanation:
the white sheep has Ww and the black has a ww since white is a dominate and heterozygous implies it has 2 versions of a gene not 2 copies of the same one so there would be a 50% chance of a white sheep with a copy of the black wool trate and a chance 50% of a black sheep
Answer:
25 and 75 percent

Identify the processes that occur during the electron transport chain.
Select all that apply.
Protons are moved across a membrane against their concentration gradient.
Carbon dioxide is released.
Oxygen is produced as a waste product.
Electrons are removed from the carrier molecules NADH and FADH2.
Answer:
Electrons are removed from Nadh and Fadh2
Explanation:
they are removed to make more ATP.
The electron transport chain (ETC) is the last step of cellular respiration, which occurs in the mitochondria.
During ETC:Protons are moved across a membrane against their concentration gradient.Electrons are removed from the carrier molecules NADH and FADH2.The ETC is a series of redox reactions that involve the transference of electrons from donors to acceptors, which is coupled to the transference of protons across the inner membrane of mitochondria.The objective of the ETC is to synthesize ATP (the energy coin of the cell) by using the electrochemical proton gradient across the inner mitochondrial membrane.NADH and FADH2 are the reduced forms of Nicotinamide adenine dinucleotide and Flavin adenine dinucleotide, respectively.In conclusion, during the electron transport chain, 1-protons are moved across a membrane against their concentration gradient, and 2-electrons are removed from the carrier molecules NADH and FADH2.

Some marshes and swamps eventually become homes to communities that include mature trees. What is this process called?
Answer: Commensalism
Explanation:
This process is called commensalism. Commensalism is considering a long-term biological process and interaction with members of one species in this case marshes and swamps and in this process, they will gain benefits while those other species benefits are not harmed, in this case, mature trees.
Marshes and swamps will become a community that is including other species but they will not be harmful to it.

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line to figure out how many kilometers a plate moved from the spreading boundary in a set number of years. Convert that rate to the distance a point moves in just one year, rounding your answer to the nearest millimeter.
Complete question:
Look at the Figure in the attached files to see the line of km per million years
Answer:
R = 16mm/y
Explanation:
Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)
R = d/t
To calculate it in millimeters per year we need to convert it:
1 km = 1000 m
1 m = 100 cm
1cm = 10mm
1 km = 1,000,000 mm
The problem states that in 150 million years, there is a distance of 2400 km.
if 1 km ------- 1,000,000 mm
2400 km-------X = 2400,000,000 mm
If 1 million years -------1,000,000 years
150 my----X = 150,000,000 years
R = d/t
R = 2400,000,000 mm/150,000,000 y.
R = 16mm/y

Jupiter's moon Europa is unique. Underneath its crust, which is made ofice, a layer of liquid water. This bound layer
likely contains more water than there is on Earth. The liquid layer causes Europa to be extremely tectonically active, with
new crust being formed constantly. How does this level of tectonic activity on Kuropa likely reduce the number of Wale
impact craters?
Answer:
As new crust forms on the surface of Europa, it erases visible impact craters. For instance, along fault lines, some areas of the crust expand while other areas melt and get absorbed into the moon’s interior.

An elephant has 56 chromosomes. Which statement about a zygote of an elephant Is true?
OA The zygote has 28 chromosomes, mostly inherited from the father.
OB. The zygote has 56 chromosomes, all inherited from the mother.
OC. The zygote has 28 chromosomes, all inherited from the mother.
OD. The zygote has 56 chromosomes, 28 inherited from the mother and 28 from the father.
OE. The zygote has 28 chromosomes, 14 inherited from the mother and 14 from the father.
Answer:
D. Because you get the same number of chromosomes from both parents
Explanation:
An elephant has 56 chromosomes, so the zygote has 56 chromosomes, 28 inherited from the mother and 28 from the father, which is in option D. Option D is the correct answer.
What is the zygote?The gametes get half of the chromosomes from the parent cell by the process of meiosis, and the male produces the sperm cell and the female produces the ovum as the gametes. The zygote is formed by the union of the male and female gametes, and the zygote inherits half of its genetic content from the father and half from the mother.In the elephant, there are 56 chromosomes in the parents, and each gamete will form 28 chromosomes, but the zygote will form 56 chromosomes.
Hence, An elephant has 56 chromosomes, so the zygote has 56 chromosomes, 28 inherited from the mother and 28 from the father, which is in option D. Option D is the correct answer.

Write a short essay about Mining Methods and Their Impacts ( 1 page). The essay must include a definition and detailed information about Strip Mining and Subsurface mining.
Answer:
Mining Methods can strip the land of their natural resources and can subsurface later. If it is used wisely, it can extract the natural sources and can be distributed out. The method can be used in different ways depending on the location and environment. Depending on the mining methods it can either deplete or replenish the land. Minerals that are gone can be replenished depending on which ones were eliminated.
Such materials like gold, coal, and zinc can be mined. Methods such as stripping these materials can be extracted from the earth. Therefore; methods like digging, dredging, and coal mining. Once all the materials are surfaced they can extract other objects after they extract all of the rest. Surface out other items such as metal and nonmetallic items from the land.
Strip mining the open surface of oil, ore, and iron. It can also strip the surface and eliminate wasteful sources such as dirt. Other wasteful sources that are acid-related can be gone. Acids and fungus in the air can be eliminated using the proper technology. Certain technology can be used to extract the proper resources.
Other methods such as underground digging and extracting materials can eliminate other stuff depending on where it came from. The biggest error in this way is that it can cause the materials to be completely depleted. They can surface items such as rings using a magnet. Furthermore, they can surface other materials that are made of metal. Finally, these people can mine other items like steel.
In conclusion, these items can come in many shapes and sizes. Mold can be depleted from certain items if it is found in damp areas. Drier areas however can have certain fungus such as bread mosts and yeast. If the items are all extracted with a certain technique then they can resort to their next option. Finally, they can use all of the aforementioned mining techniques to thrive off of the land and reach their desired impact.
