A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true?
A.
The trait for spore color is determined by exactly one gene.
B.
The trait for spore color is determined by more than one gene.
C.
The allele for black spores is dominant over that for white spores.
D.
The allele for white spores is dominant over that for black spores.
Answer:
C.
Explanation:
Since there are more of an outcome of black spores it would make sense that this trait is dominant.
White spores seem to be recessive in this case too.
I also suspect the parents are both heterozygous. They both carry one trait for black and one for white.
Hopefully this is correct. Have a great day.

You are called to investigate a lake in your home town, where the residents fear that a broken pipe from the local sewage treatment plant has turned the formerly pristine lake eutrophic. You test the water and find very low levels of oxygen. What stage of euthrophication is this lake in?
Answer:
The correct answer is - The decomposers decompose dead algae and plants which take up most of the oxygen.
Explanation:
Eutrophication is taken place when there is a high amount of nutrients, minerals are present in a waterbody which allow algae to grow rapidly and cause depletion of oxygen due to the decomposition of dead organisms. There are the following stages in the eutrophication process:
- rapid growth of Algae and other plants
- due to algal bloom, the sunlight is blocked, and plants and organism start dying.
- The decomposers take up most of the oxygen by decomposition
- The animals start dying without oxygen

Which two changes would increase the density of ocean water?
A. Increasing the amount of light that enters it
B. Decreasing its salinity
C. Increasing the amount of water that evaporates from it
I D. Decreasing its temperature
Answer:
The answer is simply D.
Explanation:
One factor that does affect density is the temperature. In general, most substances become less dense as temperature increases and more dense as temperature decreases.
The amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options C and D are both true for this statement.
What is the effect of temperature on density?
The ocean water has more salts and minerals dissolved in it, so it is denser than normal fresh water. Some factors further decrease or increase the density of the ocean water. When the temperature drops, the water cools and ice forms. The ice is denser than the water, so it will sit below it.
As the temperature rises, the water evaporates, increasing salinity because more salts are present in the ocean water than in the water itself. The concentration of salt in the ocean determines the salinity of the ocean, and it can increase the density of ocean water when the concentration of salt is higher.
Hence, the amount of water that evaporates from the ocean and the temperature are the two factors that influence its density. So options c and d are both true for this statement.

The nitrogen cycle describes how nitrogen is converted between different forms. Describe the nitrogen cycle process by completing the sentences.
1.Atmospheric Nitrogen (N_2) is converted to NH3 in a process catalyzed by __________.
2. NH_4+ is _________ to NO_2- and then NO_3- in a process called ___________.
Atmospheric nitrogen is __________ to NH_4+ as a result of ____________.
Nitrate is converted to N_2 in a process called ______________.
Nitrite conversion to NH_4+ is catalyzed by ______________.
Answer:
1. Nitrogenase
2. converted, nitrification
3. Decayed, ammonification
4. Denitrification
5. nitrite reductase
Explanation:
The nitrogen cycle refers to the series of processes that adds and removes nitrogen from the soil or atmosphere. The series of processes involved in nitrogen cycle are being described in this question as follows:
- Atmospheric Nitrogen (N2) is converted to NH3 (ammonia) in a process catalyzed by the enzyme NITROGENASE in a process called nitrogen-fixation.
- NH4+ (ammonium ion) is converted to NO2- (nitrite) and then NO3- (nitrate) in a process called NITRIFICATION.
- Atmospheric nitrogen (N2) is decomposed or broken down to NH4+ (ammonium ions) as a result of a process called AMMONIFICATION.
- Nitrate is converted to atmospheric nitrogen (N2) in a process called DENITRIFICATION.
- Nitrite conversion to ammonium ion (NH4+) is catalyzed by an enzyme called NITRITE REDUCTASE
Osmosis which is a form of passive transport
Answer:
represents the flow of water through its concentration gradient, through a semi-permeable membrane.
Explanation:
This means that water flows from where it is in a higher concentration to a place where it is in a lower concentration to try to equalize the concentrations of both solutions.
Osmosis is an example of diffusion when molecules tend to be evenly distributed in space.
How do moose use a learned behavior to protect themselves
Answer:
They roll in a pool of muddy water to avoid fly bites
Explanation:
Moose is the largest species of deer and inhabits the northern regions of Europe (Scandinavia), Siberia, Canada, and a large subspecies - the great moose - inhabits Alaska.
The moose is one of the first domesticated domestic animals. It was domesticated a long time ago - it is believed that it was about 4-5 thousand years ago, maybe even earlier.

how are the processes of photos sentences and saw your respiration opposites of one another
Answer:
This question is not well structured. Based on understanding, the correct structure should be: How are the processes of photosynthesis and respiration opposites of one another?
They are opposite because photosynthesis uses the products of cellular respiration and vice versa.
Explanation:
Photosynthesis and cellular respiration are both metabolic processes that occurs within the cells of living organisms. Photosynthesis is the process where green plants synthesize food (sugar) in the presence of sunlight using carbon dioxide (CO2) and water (H2O). The general equation is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
On the other hand, respiration is the process whereby cells of living organisms synthesize usable energy (ATP) for use by breaking down glucose (C6H12O6) in the presence of oxygen. The equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Based on the observation of the reactants and products of each process, it can be realized that the PRODUCTS of one process is the REACTANTS of the other. In other words, photosynthesis makes use of CO2 and water as REACTANTS, which are the PRODUCTS of respiration while cellular respiration uses glucose and oxygen as REACTANTS, which are PRODUCTS of photosynthesis.

how energy is recycled in an ecosystem. how our atmosphere maintains its temperature. the importance of decomposers in an ecosystem. the one-way flow of energy in an ecosystem.
Answer:
The flow of energy in ecosystems is unidirectional or one-way.
Explanation:
Energy is the ability to do work. Energy flows in one direction in an ecosystem and is not recycled. This is because during the transfer of energy from one level to another, energy is lost. Most of the energy received from the sun by producers, plants, is lost as heat to the surroundings. The rest energy is converted by plants to produce food in the form of chemical energy.
Primary consumers feed on plants and secondary consumers feed on the primary consumers and so on up to quaternary consumers. However, at each level of energy transfer, some energy is lost as heat during respiration, some as unused or undigested materials, while some others are used for each organisms metabolic activities. About 90% of energy in a trophic is used at that trophic level. Therefore, only about 10% as much energy is available to organisms at each successive trophic level. Therefore, energy is not recycled in ecosystems.
Earth's atmosphere maintains its temperature by means of the earth's energy balance. This refers to how incoming from the sun and outgoing energy from the earth are in balance, thereby keeping earth's temperature constant.
Decomposers, are organisms such as bacteria, fungi, and small animals such as ants and worms that eat and decompose dead and waste organic matter and which recycle nutrients back into food chains making them available for plants use. Therefore, decomposers are an essential components of all ecosystems.
