Answer: Turner syndrome (45,X0),
Klinefelter syndrome (47, XXY), and.
Cri du chat syndrome, or the "cry of the cat" syndrome (46, XX or XY, 5p-).
Explanation: I am learning this in college now
The genetic disorders found on chromosome 17 are neurofibromatosis type 1, Smith-Magenis syndrome, acute myeloid leukemia, etc., and these are genetic and caused by mutations in certain genes.
What is the significance of chromosome 17?The number of chromosomes varies by species; in humans, there are 46 chromosomes, 44 of which are autosomes, and one pair of sex chromosomes. When chromosome 17 is mutated, neurofibromatosis type 1 develops, resulting in bone and skin abnormalities as well as cognitive impairment and out of other diseases, one is Charcot-Marie-Tooth disease, where peripheral nerves result in muscle weakness.
Hence, the genetic disorders found on chromosome 17 are neurofibromatosis type 1, Smith-Magenis syndrome, acute myeloid leukemia, etc., and these are genetic and caused by mutations in certain genes.

The first step in the nitrogen cycle is: Soil bacteria act to "fix" atmospheric nitrogen to form ammonia. Plants take in useful nitrogen compounds from the soil ; option C
What is the nitrogen cycle?The nitrogen cycle refers to the processes by which nitrogen is cycled between the living and non-living components of the environment.
The nitrogen cycle is important as it helps provide plants with the useful nitrogen which they require for growth.
There are seven steps in the nitrogen cycle and they are:
nitrogen fixation,assimilation,ammonification,nitrification,denitrification,dissimilatory nitrate reduction to ammonia,anaerobic ammonia oxidationThe first step in the nitrogen cycle is nitrogen fixation which is the process by which atmospheric nitrogen is fixed into the soil by soil bacteria in a useful form required by plants. Therefore, step C occurs first.
In conclusion, the nitrogen cycle is important for plant growth.

Explanation:
In allium, interphase lasts about 15 hours, and mitosis takes up 80 minutes. Assuming that
each stage of mitosis takes the same amount of time, how many hours old is a cell that is just
starting anaphase. (Yes, you'll need to do some math here - show your work or explain your
reasoning)
Answer:
15 hours and 40 minutes
Explanation:
The stages of mitosis are prophase, metaphase, anaphase and telophase. Anaphase is the stage of mitosis after metaphase where replicated chromosomes are segregated to opposite poles of the cell. Anaphase is the third stage after prophase and metaphase, which in this case have the same duration (20 minutes each one). In consequence, a cell that is just starting anaphase is 15 hours and 40 minutes old.
Interphase: 15 hours
Prophase: 20 minutes
Metaphase: 20 minutes
Knowing that interphase lasts 15 hours and each stage of mitosis lasts 20 minutes, we could say that a cell that is starting anaphase is 15 hours and 40 minutes old.
-------------------------------------
Available data:
The interphase lasts 15 hoursMitosis lasts 80 hours in totalEach stage of mitosis takes the same amount of timeNow, from the theoretical framework, we know that the interphase precedes the mitosis event.
We also know that mitosis is complete after four stages:
ProphaseMetaphaseAnaphaseTelophaseSo if the cell of interest is just starting anaphase, it means that it has already gone through the interphase. Then the cell has gone through the 15 hours that the interphase takes.
If mitosis is complete in 80 minutes, and each of the four stages lasts the same, we just need to divide 80 on 4 to get the amount of time each stage takes.
80 minutes / 4stages = 20 minutes/stage ⇒ Each stage takes 20 minutes
to complete.
This cell is just beginning the anaphase, which means it has already gone through prophase and metaphase. Each of them lasted 20 minutes.
So this cell has gone through 15 hours of interphase + 20 minutes of prophase + 20 minutes of metaphase = 15 hours and 40 minutes.
We can say that this cell is 15 hours and 40 minutes old.

-Planting crops in contour strips
-Using shelterbelts to separate crop fields
-Switching from chemical to organic fertilizers
Answer:
planting crops in conotur strips, i just did the assigned reading and it literally says the answer. the other person is wrong
Explanation:
Planting crops in contour strips would be the most helpful strategy for protecting the soil from wind erosion.
• A system of alternating strips of small grains or meadow with strips of row crops on the contour is known as contour stripping.
• The method of contour stripping could minimize soil erosion by up to 75 percent in comparison to planting row crops down and up the slope.
• The strip cropping differentiates fields into narrow, long sections, which assists in monitoring erosion and runoff while growing crops in rotation.
• Contour stripping helps to conserve rainwater and minimize soil erosion.
Thus, the correct statement is planting crops in contour strips.
