.. Which pair of organisms is most likely to have adaptations in common?
Answer: the 1st one
Explanation:
A grassland predator and prey, such as a cheetah and a zebra. Therefore correct option is (A).
What organisms have common adaptations?The pair of organisms that is most likely to have adaptations in common is a pair of organisms that share similar environmental pressures or ecological niches. Organisms that occupy similar habitats, have similar diets, or face similar challenges are more likely to evolve similar adaptations over time.
For example, predatory animals such as lions, tigers, and leopards have evolved similar adaptations such as sharp claws, powerful jaws, and keen senses to help them catch prey. Similarly, desert-dwelling animals such as camels, kangaroo rats, and fennec foxes have adaptations such as the ability to conserve water, tolerate heat, and dig burrows in sandy soil to survive in their arid environments.

What is the main difference between active and passive sonar
Answer:
There are two kinds of sonar: One is passive sonar, and the other is active sonar. For passive sonar, we don't send sound waves but just receive them. By listening to these special sound waves, animals that communicate with these particular sound waves can be detected. By listening to the sound waves from engines of submarines or ships, we can locate them.
Also, other things that vibrates can be detected by passive sonar. Many threats on the sea are usually detected by passive sonar this way. Since passive sonar does not transmit any thing to the environment, it does no harm to other animals. Active sonar is a little different.
Besides having a receiver, active sonar also transmits sound waves. Active sonar works by transmiting particular sound pulse and measuring the length of time for the sound to be reflected back, then devide the time by 2 to get the time it takes for the sound pulse to reach the object

A scientists observes several fossils in a river bed. Based on these observations, she concludes that invertebrates once dominated that ecosystem. This is an example of inductive reasoning.
True
False
Answer:
False
Explanation:
It is false because inductive reasoning is a reasoning that is not based on observations but it is based on hear say,i.e what people say, what is read or news read e.t.. Therefore it is not observed. But the above us deductive reasoning because this is based on observations, theories e.t.c. it is based on what is seen or observed.
Answer:
True
Explanation:
Inductive reasoning is a method of reasoning in which conclusion are drawn on the premise of the evidence supplied. The evidence are the tools from which conclusions are drawn but not full assurance, of the truth of the conclusion.
It could also involve the individual's experiences and observations together with what are learned from others, this together help synthesize the general truth.
The fossil serves as evidence on which the scientist based her conclusions.

Flow
Explain why countercurrent flow met the goals and why parallel flow did not meet the goals.
Answer:
Fish utilise a counter-current system in order to maximise the amount of oxygen that can extracted from water. Water has a much lower oxygen content than air and as such fish need a much more efficient system that can extract a much higher proportion of oxygen from the surrounding water.
Explanation:
Counter flow created more movment and chaos, it made the molecules bump into each other more often, which makes it more likely that each individual partivle will go out of the pores. whereas parelel flow the particles move neatly along side one another

Order the following steps in the pyruvate dehydrogenase reaction. The answer is scored as ALL OR NOTHING, so all steps must be in the correct order for credit.
a) Pyruvate and thiamine pyrophosphate react form hydroxyethyl-TPP. CO2 is released.
b) The reduced coenzyme bound to PDH is reoxidized using electrons from FAD.
c) An acetyl group is added to a coenzyme bound to PDH, forming acetyl-dihydrolipoamide.
d) The acetyl group is transferred to CoA, forming acetyl-CoA.
e) Electrons from FADH2 are transferred to NAD+ forming NADH and H+.
Answer:
The correct order is:
1.- pyruvate and thiamine pyrophosphate react form hydroxyethyl-TPP, CO2 is released
2.- an acetyl group is added to a coenzyme bound to PDH, forming acetyl-dihydrolipoamide
3.- the acetyl group is transferred to CoA, forming acetyl-CoA
4.- the reduced coenzyme bound to PDH is reoxidized using electrons from FAD
5.- electrons from FADH2 are transferred to NAD+ forming NADH and H+
Explanation:
Pyruvate reacts with thiamine pyrophosphate (TPP) on the complex enzyme pyruvate dehydrogenase (E1). This process cleaves CO2 and generates acetaldehyde bound to TPP or hydroxyethylamine. E2 is Dihydrolipoyl-transacetylase and has Lipoamide attached. In the transfer from E1 to E2, the hydroxyethyl is oxidized to acetyl, at the same time that the disulfide bridge of the lipoamide is reduced to dihydro-lipoamide, although as this is acetylated, the product is acetyl-dihydrolipoamide. Acetyl group of acetyl-lipoamide (thio-acyl bond) is transferred to CoA-SH, to form Acetyl-S-CoA (thio-acyl bond).Acetyl-CoA is released into the mitonchondrial matrix. Lipoamide is reduced as Dihydro-lipoamide. The last reaction is catalyzed by dihydrolipoyl dehydrogenase, where it is reestablished in the disulfide bond of lipoamide to make it reactive again. For this, FAD is used as an intermediate, which is reduced to FADH2 and oxidizes the sulfides (which are then linked again). Finally, FADH2 reacts with NAD, which is reduced to NADH and H+ released, restoring FAD for a new reaction.
Do you think an advanced civilizations may exist in the universe? Why or why not?
Answer:
Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.
The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study.
"To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life]
In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way.
Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last.
Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface.
