Answer:
the second one is the right answer
The second evolutionary tree (2) is showing a different evolutionary history from the other trees.
What is an evolutionary tree?An evolutionary tree is a diagram/graphic used in biology to show evolutionary relationships between taxa.
The taxa located at the tree can be different species, genera, orders, etc.An evolutionary tree is monophyletic when all descendants originated from the same ancestor.In conclusion, the second evolutionary tree is showing a different evolutionary history from the other trees.

Place a single word into each sentence to make it correct, then place each sentence into a logical paragraph order. Blood leaving the chambers Waste products will then be ____________ by the tubules.
Answer:
Blood goes to lungs for the removal of carbondioxide and loading of oxygen whereas kidney filters the blood and sent the waste to urinary bladder.
Explanation:
Blood leaving the chambers and this blood goes to the lungs through pulmonary artery that carries deoxygenated blood. In the lungs, carbondioxide gas is removed from this blood and oxygen is added to the blood. This oxygenated blood goes to the heart through pulmonary vein and the heart pump this blood to all parts of the body. Waste products that is produced during metabolism in the liver will then be transported to the kidney for filtration by the tubules. After filtration the waste products are sent to the urinary bladder through ureters.

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.

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.

2. What does the atomic model teach you about the ability of scientists to
study things that cannot be directly observed?
Answer:
The atomic model is our understanding of how the atom is structured. At one point in history, people believed that any substance was simply made of that substance and would retain that property no matter how small a quantity it was reduced to. Later, some argued that all matter was made of tiny particles called atoms. While this is correct, later researchers found that even the atoms were made of smaller particles called electron, protons, and neutrons. More recently, scientists have discovered quarks, tiny particles that makeup protons and neutrons.

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).

What determines the direction of gas movement?
Answer: The direction of gas movement is determined by partial pressure differences. 2) At the arterial end of the pulmonary capillaries, O2 diffuses from the alveoli into the blood, while CO2 diffuses from the blood into the alveoli.
Explanation:
→ Oxygen and carbon dioxide diffuse across a respiratory membrane.
Factors determining gas movement:
The concentration gradient of the gases and the partial pressure of the gases.The differences in concentration on either side of the cell membrane.→ In diffusion of gases:
The amount of surface area available for diffusion.The distance the gas particles must travel.The higher the concentration gradient across the gas-exchanging surface, the faster the rate of diffusion across it.Learn more:

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.
