how are genes chromosomes and heredity related to one another?
Answer:
These two copies of the gene contained in your chromosomes influence the way your cells work. The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways. These are called inheritance patterns.

cause u have too look wiseltyA student is investigating gas production of water plants of various sizes. She predicts that larger plants produce more oxygen. She places a test tube and funnel upside down over a water plant submerged in water. The test tube collects gas the plant produces when in sunlight. A diagram of her setup is shown below.
In this experiment, what is the independent variable?
A.The number of gas bubbles
B. The varying size of the plants
C. The test tube used to collect gas
D. The temperature of water in the beaker
Answer: The test tube used to collect gas (C)
Explanation: If you illuminate a plant (I presume you are using an aquatic/water plant) it will produce oxygen. You can put the plant under a funnel and collect the bubbles in an upturned test tube. If the gas is collected fresh, it will relight a glowing splint. However, if the gas takes more than 24 hours to collect, or if you leave it for several hours before testing it, you may not relight a glowing splint.

What experiment conducted by andre jagendorf with isolated thylakoid membranes proved that possibles solutions?A. Blue and red light, but not green, caused photosynthetic production of oxygenB. The ATP synthase complex functioned as a molecular rotary engineC. Molecular oxygen (O2) is derived from water, not CO2D. ATP and NADPH are the direct products of the light reactions, not sugar.E. ATP synthesis could be energized by a proton gradient.
Answer:
The correct answer is option E, that is, synthesis of ATP could be mediated by a proton gradient.
Explanation:
Andre Jagendorf inserted chloroplasts for many hours within a buffer of pH 4 and then instantaneously mixed that with the buffer of pH 8. He came to known that in the stroma, a change in pH was witnessed, that is, it moved to 8 while in the thylakoid space there was no change, that is, the pH remained at 4. He then isolated the thylakoid and put it in the dark, he noticed that it produced ATP. This proves the hypothesis of Peter Mitchell that the production of ATP is mediated by proton-motive force.

How does cellular respiration happen?
Answer:
Explanation:
Hello there! Cellular respiration is the process in which the body breaks down sugar, glucose, within the body. When this glucose is broken down it will be transformed into ATP, Adenosine triphosphate, the energy used within almost all bodily processes. Although the means by which the body breaks down this sugar is rather complex it would be easiest to understand the chemical reactions that make up the process.
one of the many chemical reactions in cellular respiration is as follows:
C6H12O6+6O2⟶6CO2+6H2O+Energy
In the reaction above we see a sugar, C6H12O6, reacting with carbon dioxide. When these two products completely react they will produce water, H2O, carbon dioxide, CO2, and ATP, labeled as energy.
Hope this helps!

A certain wastewater treatment plant uses aerobic bacteria, anaerobic bacteria and archaebacteria during secondary treatment of sewage. Unfortunately, during a bad bluzard the sludge digester froze, killing the microbes inside. What is likely to result? a) Floc levels will diminish b) Solid material will not be effectively fitered out c) Methane production will go down d) Floc will not be effectivelyftered out
Answer:
The correct option is C
Explanation:
Anaerobic bacteria used in sewage treatment helps to reduce the volume/amount of sludge in the sewage thereby producing methane gas from it. Some companies produce there own (not for sale) methane gas (as an alternate source of energy) through this process. Thus, a decrease in the amount of this bacteria (perhaps through death as described in the question) will lead to a decreased production of methane gas.

3. What atoms are parts of the process of photosynthesis?
Answer
Photosynthesis involves three elements: carbon, hydrogen, and oxygen. You have seen that the products of photosynthesis are oxygen and glucose. Their chemical formulas are shown below.
Answer:
carbon, hydrogen, and oxygen
Explanation:
In photosynthesis, the energy from the sun eventually gets converted into chemical energy in the form of ATP and sugar that the plant can use directly to fuel its biological processes. Which of the following correctly describes how plants use glucose after it is produced?
Answers:
Glucose enters the mitochondria for production of ATP.
Solar energy breaks apart glucose forming pyruvate.
The energy in glucose is never used by the plant.
Glucose is broken down into its components ATP and H ions.
Answer:
Glucose enters the mitochondria for production of ATP.
Explanation:
Photosynthesis is the process through which solar energy is used to make glucose.
To generate chemical energy for cellular processes, glucose is broken down through cellular respiration in the mitochondria. This generates large amounts of ATP, which acts a source of energy to power reactions in the cell.
Excess glucose is stored as starch in plant cells

Examine a two-gene cross in which a mutation in HERC2 is epistatic to the OCA2 gene. In a cross between a blue-eyed OOhh woman and a blue-eyed ooHH man, what eye color will the progeny have?
a. 9 brown eyes: 7 blue eyes
b. 3 brown eyes: 1 blue eyes
c. All blue eyes
d. All brown eyes
In recessive epistasis, the epistatic gene -HERC2- in h0m0zyg0us recessive state inhibits the expression of the hypostatic gene -OCA2-. In the example, the F1 is heter0zyg0us for both genes. Option D. All brown eyes.
Epistasis
When talking about epistasis, we are referring to an interruption.
These are interactions between genes located in different loci in the same chromosome.
An epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.
When the epistatic gene is recessive, the interaction is known as recessive epistasis.

F1) 100% of the progeny will be heter0zyg0us for both genes, expressing brown eye color.
Among the progeny, neither of the genes is in h0m0zyg0us recessive estate, meaning that the expression of brown eyes is possible.
The eye color among the progeny is expected to be 100% brown eyes. Option D.
