Which fact about those structures best supports one aspect of theory of evolution?

The fact that the bone structures are similar supports the concept that birds evolved from mammals.
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
The fact that the bone structures are completely different supports the concept that those organisms shared a common ancestor.

Answers

Answer 1

Answer:

The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.

Explanation:

Answer 2

The similarity of the wings of bats, legs of alligators, and arms of humans in structure is an indication that animals shared a common ancestor according to the evolution theory.

Homologous organs are organs found in different organisms that are similar in structure but different in functionality.

The fact that these organs are similar to each other in morphological structure points to the fact that they might have evolved from the same ancestor according to evolutionists.

The wings of bats, legs of alligators, and arms of humans are all based on the same pentadactyl (five-digit) structure. However, a bat uses its wing to fly, alligators use their legs to crawl, while humans use their arms for a variety of purposes.

The homologous organ is one of the pieces of evidence used to support the evolution theory.

A scientist studies the DNA in corresponding genes of a platypus, a

beaver, and a duck. The DNA from which two species are most likely to be most

similar? Explain your answer.

Answers

Answer:

platypus and a duck has similar DNA.

Explanation:

There are certain similarities which are present between duck and platypus such as structure of beak or mouth, webbed feet and laying eggs in order to continue its generation. These three characteristic make the platypus and duck similar to each other. There is also one major difference is present which is that the platypus is the only mammal which lay eggs and feed baby with their own milk. Its tail structure is also different from duck.

The DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

Sequence homo-logy refers to the level of similarity between nucleotide (DNA) sequences due to shared ancestry in the evolutionary history of life.

The species that share a more recent ancestor exhibit a higher level of sequence homo-logy than unrelated species.

In this case, the linear order of nucleotides in DNA from platypus and beaver are most likely to be most similar because they are mammals, while ducks are birds.

In conclusion, the DNA from platypus and beaver are most likely to be most similar because these species share a more recent ancestor.

2. It releases the oxygen needed by plants for photosynthesis.
3. It converts sugars to usable energy that all organisms need.
4. It helps animals digest the sugars when they eat plants.

Answers

Answer:

1. Producers create energy for other organisms to consume.

2. It converts sugars to usable energy that all organisms need

Explanation:

All living organisms require energy, which they obtain by feeding on one another in an ecosystem. The series of feeding steps involved is called FOOD CHAIN. Food chain always starts with an organism called PRODUCER, which is an autotroph i.e. capable of producing its own food by using light energy from sunlight e.g plants. All other organisms in the food chain are directly or indirectly dependent on plants to get energy. This is because plants and other autotrophs create the energy that is being transferred as the food chain progresses.

2. Cellular respiration is an important phenomenon for all living organism because it is the metabolic process by which they obtain the usable energy by their cells i.e. ATP. Food molecules in form of sugar (glucose) eaten by organisms are broken down in the presence of oxygen (aerobic) to yield ATP molecules, which is the energy currency of every living cell. This energy is used to perform the organism's life activities.

In the United States, the moon’s pull is strongest during which season?
1. spring
2. summer
3. fall
4. winter

Answers

Answer: Spring

Explanation:

Gravitational pull is affected by mass and distance. Since the moon’s mass does not change, the moon’s distance between Earth and the moon is the main consideration for the strength of lunar gravity. The moon’s pull on Earth waxes and wanes as the moon follows its elliptical orbit around the Earth, the distance between the two celestial objects increases and decreases. When they are nearest to each other, the moon is in the point of its orbit called the perigee, and its pull on Earth is the strongest.

On Earth, the moon’s gravity primarily is manifested as high and low tides, as the water bulges toward the moon. The effects of lunar gravity are felt the most at the constantly changing spot on Earth that is directly beneath the moon, called the sub-lunar point. At most times of the year, the moon has a greater pull on Earth than the sun does, but this changes during the times of year when the Earth’s orbit brings it closer to the sun. At these times, the sun’s gravitational pull causes spring tides, and when these coincide with the moon’s orbital perigee around the Earth, they are called perigean spring tides.

Earth exerts a gravitational pull on the moon 80 times stronger than the moon’s pull on the Earth. Over a very long time, the moon’s rotations created fiction with the Earth’s tugging back, until the moon’s orbit and rotational locked with Earth. This is called "tidal locking," and it explains why the same side of the moon always faces the Earth.

Clear cutting can cause secondary succession. So, the correct option is A.

What is Secondary succession?

When a place is disturbed but not severely enough to completely clear it of all vegetation and soil, secondary succession happens. Secondary succession can be started by a variety of disturbances, including fire, flooding, high winds, and human activities (such as logging of forests).

After the primary succession has indeed been disrupted as well as some animals and plants are still there, the secondary succession occurs. For the reasons listed below, the secondary succession is typically quicker than the primary succession.

There is already earth in place.The soil may still contain seeds, roots, and subsurface vegetative organs.

Define natural selection and give Example with detailed explanations.

Answers

Answer:

Natural selection is when animals who are able to survive in their environment flourish, and those animals who aren't die out.

Explanation:

Lets say there were two rival animals, we can call them plantoids 1 and 2. These plantoids were both trying to out-survive each other. The problem is birds loved to eat them, so through evolution plantoids 1 began producing toxins, so when chewed on the bird would be poisoned. For awhile this worked, and the plantoids without it were dying off. Then plantoids 2 created a thorn on their heads, and were able to blend well. This worked well, and sadly for plantoids 1 the birds were able to eat them. The birds went through natural selection and those who were immune to the poison survived. Now these two plantoids are two completely different species, and they were once the same. In the end plantoids 2 survived because they were more adapted to the setting they lived in.

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end of anaphase. Before cytokinesis has begun? Hint: first of all, state the number of chromosomes. Then explain why you think so.

Answers

Answer:

20 chromosomes

Explanation:

Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.

In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.

Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
