Answer:
Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything
The question is incomplete,below is the complete question.
Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"
You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."
QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?
Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.
Why are viruses not living??
Answer:
Viruses are not living cause they need any host (body or living organism) To perform its function.
Explanation:
Answer:
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own way they can do nothing until they entered a living cell. Without cells viruses will not be able to multiply. Therefore viruses ante not living things.
how do i explain this?
Answer:
Oxygen debt is a physiological phenomenon in which a person consume oxygen at fater rate that it replaced by new oxygen molecules.
As shown in the graph, oxygen debt occurs just after the end of exercise because oxygen is consumed at faster rate during exercise that leads to increased respiration and body attempts to replace the used oxygen.
To overcome the problem of oxygen debt, a person should take rest that allows the body to replenish its oxygen supply.

Una planta de flores púrpura se cruza con una planta de flores blancas, obteniéndose una descendencia en la segunda generación filial de 50 % heterocigotas, 25% homocigotas dominantes y 25% homocigotas recesivas. (el color púrpura domina sobre el blanco) Diga: ¿Qué genotipos y fenotipos tienen los padres para que se cumpla esta proporción en la segunda generación? ¿A qué la ley que corresponde? ¿Por qué los padres presentan ese genotipo y cuál es el fenotipo que expresan la segunda generación filial? Explique. Demuestre con cruces
Answer:
Los padres son homocigotas y la F1 estará formada por individuos heterocigotas
Explanation:
El cruzamiento entre un ejemplar homocigota dominante P (flores púrpura) y un homocigota recesivo p (flores blancas) para un rasgo determinado por un sólo un gen con dominancia completa producirá una generación filial F1 100% heterocigota. Por su parte, cuando cuando estos individuios cuyo genotipo es Pp se cruzan entre sí, los genotipos esperados en la F2 serán 1 (PP, homocigota dominante): 2 (Pp, heterocigota): 1 (pp, homocigota recesivo). Esta aserción corresponde a la segunda ley de Mendel, la cual es conocida como la Ley de Segregación Independiente.

1. Haemophilia.Colour blindness, thalassaemia, night blindness
2. Gene. Chromosome. Allele, Ovule
3. Diffusion. Imbibition. Osmosis, Oxidation
4. Seed shape. Seed colour. Flower position. Inflorescence
Answer:
1. night blindness
2. Ovule
3. Oxidation
4. Inflorescence
Explanation:
1. Night blindness is odd among haemophilia, colour blindness, thalassaemia because night blindness is not an inheriditary disorder while other three are inheriditary diorder.
2. Ovule is odd among gene, chromosome, allele, ovule because ovule develops into a seed when fertilized and is not a part of genetic material DNA while the other three are part of genetic material.
3. Oxidation is odd among diffusion, imbibition, and osmosis because other belongs to the method of conduction of water and minerals by plants.
4. Inflorescence is odd among seed shape, seed colour and flower position because inflorescence is a group pf flower is flower axis while other belongs to a characteristic of a single or individual flower.
Hence, the correct answer is:
1. night blindness
2. Ovule
3. Oxidation
4. Inflorescence

In 1998, scientists discovered that the expansion of the universe has been accelerating.
What force is causing this phenomena?
dark energy
Hubble's law
the Doppler effect
background radiation
Answer:
Option A (dark energy) is the right answer.
Explanation:
A hypothetical supplier of power that creates a force that contradicts gravity, which is assumed to have been the catalyst of accelerated universe development. Hypothetically, dark energy counteracts the kinetic energy including its beginning of the globe, meaning that perhaps the multiverse does not have intrinsic curvature, although observational measurements presently indicate.Some other three choices have no relation to the particular situation. Thus option A would be the right solution.

please help me. I been stuck on this question for a long time :(
Answer:
Explanation:
1. Climate change is caused by changes in the earth's atmosphere in the amounts of greenhouse gases released into the air. Some scientists believe that 100% of global warming is due to humans. The largest contribution comes from burning fossil fuels because it releases carbon dioxide gas to the air, which is done by humans. Other factors that contribute to climate change include:
>Deforestation- clearing out trees affects wildlife, ecosystems, whether patterns. Forests cover 30% of the lands mass and clearing them leaves many animals without homes.
>Waste from factories- they release tonnes of toxic fumes into the air.
> Agriculture and farming- this is a surprising contributing factor to global warming. Animals produce a greenhouse gas called methane and when livestock are grazed at a large scale, the amount of methane produced is a big contributor to global warming.
Some fertilizers release nitrous oxide, which is another greenhouse gas.
2. The effects of global warming include:
>Melting glaciers- this leaves many animals without homes and it also causes a rise in sea levels which causes flooding. (that's 3 effects)
>Worsening droughts- this leaves many humans to die as they have no food or water.
>Increasing tornadoes

Why are NADH and FADH2 necessities in the electron transport chain?(1 point)
They power the electron transport chain.
They power the electron transport chain.
They remove electrons from the electron transport chain.
They remove electrons from the electron transport chain.
They move down the electron transport chain.
They move down the electron transport chain.
They move electrons to the electron transport chain.
NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.
More about the electron transport chain can be found here: https://brainly.com/question/13975046
Answer:
The correct answer is They move electrons to the electron transport chain.
