Flower diameter in sunflowers is a quantitative trait. A plant with 6-cm flowers, from a highly inbred strain, is crossed to a plant with 30-cm flowers, also from a highly inbred strain. The F1 have 18-cm flowers. F1 × F1 crosses yield F2 plants with flowers ranging from 6 to 30 cm in diameter, in approximately 4-cm intervals (6, 10, 14, 18, 22, 26, 30). An 18-cm F1 plant is crossed to a 6-cm plant. What is the probability of an offspring with one additive allele, if all genes that influence this trait are unlinked?a. 1/3b. 1/4c. 1/6d. 3/8e. 1/16

DCCD (dicyclohexylcarbodiimide) inhibits oxidative phosphorylation when the substrate is mitochondrial NADH. DCCD is a drug that binds to ATP synthase and blocks proton transport through the ion channel. A) Explain what the consequences are of DCCD on cellular energy production. B) Suggest at least one other cellular effect of DCCD, and prepare an explanation of this effect.
Answer:
A) Decreases cellular energy production
B) DCCD also affects K+ transport
Explanation:
A) Consequences are of DCCD on cellular energy production: Decreases cellular energy production
ATP-synthase pump is composed of two subunits: F1 catalytic subunit that synthesizes ATP, and F0 proton pumping subunits, that transport H+ through the membrane. F1 subunit might act independently of F0 to produce ATP, but this molecule can not be released without H+ gradient, which generates a movement necessary for ATP release from the catalytic center.
When any of the parts composing F0 react with DCCD, the subunit can not transport H+ through the membrane. DCCD inhibits the enzyme activity by blocking the protons´ flow.
As DCCD blocks the protons´ flow, and the protons´ flow is necessary to release the ATP molecule from the F1 subunit, no other ADP + Pi can enter to F1 subunit, and the production of ATP stops.
B) Other cellular effects of DCCD
There seem to be other effects of DCCD on cell activity, some of which are still under study. To name a few:
Diimide from DCCD seems to stimulate cytochrome b reduction and inhibits its reoxidation by ferricyanide. When exposing the cell to high concentrations of DCCD for a long time, might occur an alteration in the electron transporting chainInhibition of ubiquinol-cytochrome c reductase activity when exposing the cell to high concentrations of DCCD.Inhibition of K+ transport, associated with the inhibition of H+ transport.Concerning the effect of DCCD on the K+ transport, DCCD stops the extrusion of H+ and the consequent intrusion of K+.
DCCD strongly inhibits the simultaneous flow of H+ and K+. First, it inhibits H+ flow, acidification of the environment stops, but at this point, K+ keeps moving through the membrane. Once the H+ flow has ceased, the K+ flow slowly decreases until it finally stops moving. There is a lag time in the DCCD effect on K+ flow to the instantaneous effect on H+ flow.

Describe how protists are helpful and harmful to humans and other organisms
( put this in a paragraph please)
Also describe how fungi are helpful and harmful to humans and other organisms. ( put this in a paragraph also please)
Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

The energy flow in a food web typically starts with primary producers, such as plants, algae, and some bacteria, which convert sunlight or chemical energy into organic matter through photosynthesis or chemosynthesis.
For every higher level, only 10% of the energy of the lower level is transferred.

Which gas has recently increased in the mesosphere, creating a rise in water vapor which has led to the formation of high-altitude clouds that are visible at night?
A) Ozone
B)Methane
C)Carbon Dioxide
D)Hydrogen
Answer:
I'm not 100% sure but I'm positive the answer was or is Methane, correct me if I'm wrong!
Methane levels in the mesosphere have lately risen, causing an increase in liquid water, that has resulted in the production of high-altitude storms visible at night.
So, option B) is correct.
Define Mesosphere.The mesosphere is the third layer of the atmosphere, located directly above the stratospheric and under the thermosphere. Temperature falls as altitude climbs in the mesosphere.
Methane levels in the mesosphere have lately risen, causing an increase in liquid water, that has resulted in the production of high-altitude storms visible at night.
Methane is a chemical molecule that has the formula [tex]CH_{4}[/tex].

What is the meaning of pathophysiology
Diabetes can result in inadequate blood flow, nerve damage, and severe foot issues. One method to help prevent it is by controlling your blood sugar.
What is Diabetes?A collection of illnesses known as diabetes mellitus alter how the body requires blood sugar. The cells that comprise the tissues and muscles rely heavily on glucose as a source of energy.
Each form of diabetes has a different primary etiology. Yet, diabetes can result in an excess of blood sugar regardless of the type you have. Serious health issues can result from an excess of sugar in the blood. Diabetes can result in inadequate blood flow, nerve damage, and severe foot issues. Diabetes that is not controlled can result in amputations, mainly of the legs, foot, or toes. One method to help prevent it is by controlling your blood sugar.
Therefore, diabetes can result in inadequate blood flow, nerve damage, and severe foot issues.

How can poor nutrition lead to a change in trait expression?
Answer: Poor nutrition won't provide healthy amounts of energy to the body. The lack of nutritional vitamins that the body needs can lead to a change in hormonal signals, stimuli, and metabolites.
Hope this helps :)
In the overall health management, nutrition plays a very recognizable function, however, the role of genetics in nutritional impact is yet to be understood completely.
• Genetic variability in relation to nutrition may be partly accountable for differences among the individuals in metabolism, absorption of food, enzyme digestion, excretion, storage, and others.
• Nutrigenetics and nutrigenomics are the two areas of study regarding genetics and nutrition that looks for the effect of genetic variations on dietary responses, and the function nutrients perform in bioactive food compounds and expression of the gene.
• The three prime factors in nutrigenomics and nutrigenetics are ethnic diversity, malnutrition, and availability of food.
• In the existence of chronic malnutrition, the genomic stability and gene expression can be influenced, with genome stability sometimes resulting in mutations of gene sequences and mutations at the levels of chromosomes.
Thus, poor nutrition can result in the change in the expression of trait.
