Someone expressing a recessive hair color has _______.
A-1 dominant and 1 recessive allele for hair color
B-2 dominant alleles for hair color
C-2 recessive alleles for hair color
Answer: The answer would be C
Explanation: This is because in order to express a recessive trait one must have no dominant alleles or otherwise the dominant would win out and be expressed instead. For example, if a person had 1 allele for brown hair and 1 for red the brown would win and the same would happen if they had 2 brown hair alleles. Whereas if a person had two alleles for red hair and none for brown, only then would the red trait be expressed. Hope this helped!

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1.Nitrification happens when soil organisms change over ammonium into nitrate. Much of the cover between the carbon cycle and the nitrogen cycle happens within the soil, in forms conducted by soil organisms. Organisms break down supplements, construct modern compounds for their possess development, and inevitably pass on.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like vitality particles, fats and proteins, in the long run cycling its way back into the environment. Nitrogen is basically found within the air as well and enters the environments as supplements for plants. Water, nitrogen and carbon cycles. Carbon moves from the air and back by means of creatures and plants. Nitrogen moves from the environment and back by means of living beings. Water moves on, over, or underneath the surface of the Soil.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice disintegrate and shape the arrive. Volcanic movement and seismic tremors change the scene in a sensational and frequently savage way. And on a much longer timescale, the development of earth's plates gradually reconfigures seas and landmasses. Each one of these forms plays a part within the Cold and Antarctica.
People affect the physical environment in numerous ways: overpopulation, contamination, burning fossil powers, and deforestation. Changes like these have activated climate alter, soil disintegration, destitute discuss quality, and undrinkable water. Earth's surface is the as it were territory accessible to the human race. Understanding the forms by which that environment has been made and persistently changed is critical to decide the causes of natural degradation.

During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. Which statement best describes the motion of the plates along these boundaries that causes the earthquakes?
Answer:
Although you have not put the answer options, the movement of the plates in the situation shown above occurs with the approach of their continental plates that collide and bend due to the impact.
Explanation:
The converging movement of the plates indicates that two plates are moving towards each other until they collide. When these two plates are continental, the movement is called continental-continental convergent.
As the two continental plates have the same density, the impact between the two causes them to bend and not sink into each other.
Answer:
D) the plates smash together with no subduction

The cause of humanity's increased water consumption is an increased population. What is the effect?
Option are not provided in the question. The complete question is as following:
The cause of humanity's increased water consumption is an increased population. What is the effect?
A. less potable water, a growing threat to biodiversity
B. more potable water, a growing threat to biodiversity
C. less potable water, a decreased threat to biodiversity
D. more potable water, a decreased threat to biodiversity
Answer:
A. less potable water, a growing threat to biodiversity
Explanation:
The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .
Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.
Freshwater or portable water play very important role to control flood and erosion.
So, decrease in portable water result into decrease in biodiversity.
Hence, the correct option is A. less potable water, a growing threat to biodiversity .

A student is given five samples and told they are lysine (an amino acid), lactose (a disaccharide), insulin (a protein hormone), RNA and fat. The samples are in test tubes marked 1-5, but the student doesn't know which compound is in which tube. The student is instructed to identify the contents of each tube. Base on these data, identify what is in each tube. In her first test, she tries to hydrolyze a portion of the contents of each tube. Hydrolysis occurs in all tubes except tube 3. In the next test, she finds that tubes 1, 2, and 3 are positive for nitrogen but only tube 2 gives a positive result for the presence of sulfur. In the next test the student shows that the compound in tube 1 contains a high percentage of phosphate. In the final test the student shows that compound 5 is hydrophobic. Base on these data, identify what is in each tube. 1 2 3 4 5 A. lactose B. RNA C. lysine D. fat
Answer:
1. RNA 2. Insulin 3. Lysine 4. Lactose 5. Fat
Explanation:
RNA contains both nitrogen and phosphate hence it is the substance in tube 1.
Insulin being a protein contains sulfur hence it is the substance in tube 2.
Lysine does not hydrolyse hence it is the substance in tube 3.
Fat is hydrophobic hence it is the substance in tube 5.
Since lactose does hydrolyse and because the rest have been identified, it must be the substance in tube 4.
Based on these data, each tube is identified as:
tube 1: RNAtube 2: Insulintube 3: Lysinetube 4: Lactosetube 5: Fat1. first testHydrolysis doesn't occur in lysine so, the 3rd tube contains lysine.
2. second testNitrogen is present in Insulin(in amino acids), RNA(in nucleotides), and Lysine. Insulin consists of two polypeptide chains (A and B) which are joined by sulfur bonds. So, 2nd tube contains insulin.
3. third testIn RNA, nucleotides are present which consists of phosphate groups. Adjacent nucleotides are joined together by phosphodiester bonds. So, 1st tube contains RNA
5. 4th testFatty acids are Hydrophobic due to the presence of long hydrocarbon chains. So, 5th tube contains Fat.
