How could one determine if two
unidentified organisms share a common
ancestor?

Answers

Answer 1

Answer:

Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.

Explanation:

DNA

They can look at the DNA it's the most common one.

There are 4 pieces of evolution and they are

Fossils , Geography , Embryos / DNA , Anatomy

Fossils: Physical remains of species , Determine age, location,  environment

Deeper layers = older

Geography: Proves species share common  ancestors, depending on where

they live

DNA: BEST evidence because it’s the  MOST ACCURATE

Similarities in the early stages of  development

Similarities in DNA

More similarities = closely related

More differences = not related

Anatomy: Compare body parts of different  species to see how they evolved

3 different structures:

Homologous (same structure,  different function)

Analogous (similar structure,  different organisms)

Vestigial (body parts that no  longer serve a purpose)

All of that are in evolution

When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this
description, in which two ways is energy conserved when people run?
-Heat energy is released from the body to the surroundings.
-Heat energy is taken from the surroundings to the body.
-Chemical energy is converted to mechanical energy that's used for muscle movements.
-Radiant energy is converted to mechanical energy that's used for muscle movements.
-Heat energy is converted to mechanical energy that's used for muscle movements.

Answers

Heat energy is released from the body to the surroundings and Chemical energy is converted to mechanical energy that's used for muscle movements are the  two ways in which energy is conserved when people run.

To do the things you do every day, you need energy. When you eat food, your body can use the chemical energy in the food to move your muscles, allowing you to breathe, walk, run, jump, lift things, and do everything else necessary for survival.

The chemical energy in food is converted into mechanical energy by moving muscles.

Chemical energy in the form of glucose in our food is converted into mechanical energy in the human body during movements such as running or lifting heavy objects. The muscles act as a transducer, converting chemical energy to mechanical energy through muscle contraction.

The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.

Answers

Answer:

According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.

Explanation:

The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.

In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.

What are the locations and end products for the processes of transcription and
translation?

Answers

We know so much about our bodies and how to stay healthy, for example. We also know how to make machines and devices that make life easy for us. Scientists dedicate their lives to knowledge, but even with a lifetime commitment, sometimes scientists fail to find all the answers. One mystery that still remains unsolved is why we yawnwhat makes us yawn and what purpose it serves.Recent studies suggest that we yawn when we get tired as a way to encourage our brains. The theory is that yawning helps cool the brain, allowing it to work more efficiently. According to WebMD's article about these studies, when you yawn, your jaw muscles get stretched, increasing blood flow to your neck, face, and head. Also a deep breath during the yawn forces spinal fluid and blood down from the brain. The cool air then cools down these fluids.Other scientists believe, however, that yawning is a form of communication. This theory attempts to explain why yawning seems to spread from person to person. This kind of behavior is called "contagious yawning" and carries with it a possible social message. Scientists are not yet sure what exactly the message is, but they believe people who have more social empathy are more likely to start yawning when they see someone else yawning.Scientists will continue to investigate the mystery of the yawn. Is it a leftover behavior from before humans had language? Was it a "Hey, I'm sleepy. Let's go to sleep" message? Or is it really just a way to keep our brains cool? While this behavior still is largely a mystery, one thing is certain: you are probably fighting the urge to yawn right about now.Which word from the text best describes scientists' understanding of the yawn?a.

Kennedy's Inaugural Address, 1961In your hands, my fellow citizens, more than in mine, will rest the final success or failure of our course. Since this country was founded, each generation of Americans has been summoned to give testimony to its national loyalty. The graves of young Americans who answered the call to service surround the globe.Now the trumpet summons us againnot as a call to bear arms, though arms we need; not as a call to battle, though embattled we arebut a call to bear the burden of a long twilight struggle, year in and year out, "rejoicing in hope, patient in tribulation"a struggle against the common enemies of man: tyranny, poverty, disease, and war itself.Can we forge against these enemies a grand and global alliance, North and South, East and West, that can assure a more fruitful life for all mankind? Will you join in that historic effort?In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibilityI welcome it. I do not believe that any of us would exchange places with any other people or any other generation. The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve itand the glow from that fire can truly light the world.And so, my fellow Americans: ask not what your country can do for youask what you can do for your country.My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man.Finally, whether you are citizens of America or citizens of the world, ask of us the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on earth God's work must truly be our own.Consider this sentence from the text:The graves of young Americans who answered the call to service surround the globe.What figure of speech is Kennedy using in this sentence, and what does he want to make his listeners feel? He is using irony to suggest sympathy for Americans who have died in battle over the years. He is using hyperbole to make listeners feel inspired by the sacrifices of those who have gone before them. He is using personification to compare live Americans with those who have died fighting for their country. He is using simile to compare audience members with Americans who have fought and died for their country. 9 = -5b - 23What is b? All over the world, animal habitats bump up against human development. Where these two worlds collide, animals almost never fare well. Highways, where humans speed by large tracts of natural habitat like missiles of doom, are especially dangerous for wild creatures. They can also be deadly, not just for individual animals but for entire species. The Florida panther, for example, has such a low population that each time one is killed on a highway, it is a catastrophic loss.There is hope, however, in a new way of helping animals cross through highway areas unharmed. Wildlife overpasses give animals a way to cross highways without risking their lives. These look and work like bridges but are usually covered with grass and trees that make animals like deer feel welcome. The cars drive through a tunnel under the bridges. Fences along the top edges keep the animals safe.These overpasses also connect habitats, so along with deer, the coyotes who hunt them can cross. This allows both species to have a larger range, which also helps their long-term survival. To the animals in these habitats, the overpasses may be like an extra safety net that helps them survive a drought. The bridges are especially important for animals that migrate. For centuries, animals like elk and buffalo migrated on trails that still, now, lead right up to the edges of major highways. With the help of these bridges, migrating animals can still follow their long-used paths unharmed.In some cases, these overpasses benefit humans directly as well. In these cases, the overpasses are part of a green space or park that people use for cycling, backpacking, or jogging. The overpasses give humans access to areas they may not have been able to see but also provide safety for animals.The next time you are traveling on a highway, keep a lookout for a wildlife passage. With attention to how our lives affect the natural world, we can find clever solutions, like wildlife passages, that help animals and improve our lives, too.Extra! Extra!Not all wildlife accommodations for highways are overpasses. In some cases, certain species are so important that underpasses or underground tunnels are built. In Florida, two such underpasses help turtles, snakes, and alligators that often migrate from one body of water to another. Since these creatures do not have much speed, crossing a highway for them is even more deadly than it is for swift animals like deer. Working like a large funnel, these underpasses usually require a barricade or fence alongside the highway that forces animals toward a tunnel. Aquatic turtles especially benefit from these tunnels as they lay eggs in holes dug in dry ground, away from the lake they live in.Which line shows there is hope for wild animals?
