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.
Answers
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.
Answer:
B. The trait for spore color is determined by more than one gene.

Answer: The history of science is also a history of people resisting new discoveries that conflict with conventional wisdom.
Explanation: When Galileo promoted Copernicus’ theory that the Earth revolves around the sun – counter to church doctrine about the Earth being the center of the universe – he wound up condemned by the Roman Inquisition in 1633. Charles Darwin’s theory of evolution – that new species develop as a result of natural selection on inherited traits – ran into opposition because it contradicted long-held scientific, political and religious beliefs. Alfred Wegener’s 1912 proposal that Earth’s continents move relative to each other – the theory of continental drift – was rejected for decades, in part because scientists held fast to the traditional theories they’d spent careers developing.

Answers
The complete question is as follows:
Regarding the General Adaptation Syndrome, a short term response to stress in which glycogen is broken down to glucose is characteristic of the stage. 1) Alarm reaction 2) Stage of resistance 3) Stage of exhaustion
Answer:
The General Adaptation Syndrome or GAS explains the pattern of responses that body experinces in response to prompted by a stressor. There are three phases of this syndrome:-
1. Alarm reaction:
Sympathetic system and Hypothalamopituitary axis activated by the stress result in reaction by body.
2. Stage of resistance:
The hormone that is releases continusoly in this stage by the zona fasciculata layer of adrenal cortex is cortisol to maintain arousal.
3. Stage of exhaustion:
In abscence of enough blood sugar or glucose in the body, the body initiates breakdown of the glycogen (stored sugar in muscles mosty) with the help of hormone known as glucagon to covert it to glucose so that it can be used by the cellular respiration.

In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.
How is the respiratory and circulatory system of amphibians?Amphibians have three structures for breathing:
The lungsThe mucous membranes of the pharynx and mouthand The skin.The lungs are made up of two bags with no internal division. When still in the larval stage, they breathe through gills.
How does the circulatory system of amphibians work?Amphibians have a dual circulation, meaning the blood passes through the heart twice to complete the cycle. The blood reaches the heart, travels towards the lungs, returns to the heart and only then is carried to the body.
Whit this information, we can conclude that In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.

What is the material that allows plants to capture energy from the sun? How many different types of this material are there? (site 1)
Answers
Answer: The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. This is the process called Photosynthesis, by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.
Explanation:
During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food). The photosynthesis process occurs in all plants and algae, as well as in some bacteria species.

For the Hill Reaction, you used DCIP dye at a concentration of 1x10-4 M. Our lab technicians have stock solution at a concentration of 100mM. Explain how you would make 100mL of the DCIP for you to use in a Hill Reaction lab.
Answers
Answer:
by diluting the DCIP dye stock solution 1000 times. It can be done by diluting 0.1 ml of the DCIP dye stock solution with 99.9 ml of distilled water
Explanation:
1 millimolar (mM) = 0.001 M
1.0 × 10⁻⁴ Molar (M) = 0.0001 M = 0.1 mM
Stock solution = 100 mM = 0.1 M
100 mM DCIP dye solution diluited 1000 times >> 0.1 mM = 1 x 10⁻⁴ M

Answers
Bacteriophage and E.coli are alike in the sense that they both lack membrane-bound organelles.
What are bacteriophage?Viruses that infect bacteria are called bacteriophage. The words bacteriophage mean "bacteria eater". Bacteriophages take over the machinery of host cells to produce copies of themselves and then destroy the host cell in the process.
Bacteriophages are composed of a supercoiled nucleic acid which is surrounded by a protein capsid.
A bacteriophage adheres to the surface the susceptible bacteria and injects its genetic material. This way they occupy the genetic machinery of the host and produce several copies of their own nucleic acid and also the protein capsid to surround it.
The result is the lysis of bacterial cell and release of thousands of bacteriophage viruses which are capable of infecting more bacteria in the same manner.
Bacteriophage are acellular structures lacking any membrane bound cell organelles. E.coli is a kind of prokaryotic bacteria which also lack membrane bound organelles.
Therefore, the correct option is D.

Do you believe that all of our actions can be attributed to the nervous system? Does your memory of an event trigger your responses? Why or why not?
Answers
Answer:
The nervous system is made up of all the nerve cells in your body. It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain. Metabolic processes are also controlled by the nervous system.
