A population of rabbits lives on one side of a wide river. Another population of rabbits lives on the opposite side of the river. They cannot cross the river. If speciation occurred as a result of the river, what kind of speciation was this? ___________

Answers

Answer 1

Answer:

Allopatric speciation

Explanation:

The kind of speciation that occurs when 2 populations of rabbits separated by water become different species is allopatric speciation.

Allopatric speciation occurs when two populations of the same organisms become physically separated and each population ends up developing unique characteristics that make them distinct species. This is as opposed to sympatric speciation in which a new species just spontaneously emerge from the existing population without any being separated from the population.

Other forms of speciations include parapatric speciation which occurs as a result of the spreading out of a population over a large geographical area and peripatric speciation which occurs as a result of the breaking off of a small group from a large group of organism.

In the illustration, the two populations of rabbits are separated physically by the river. Hence, the speciation that will occur if each population goes ahead to form a new species would be allopatric speciation.

The marine biologist from the nursery is planning to develop a large number of new coral polyps with large stinging tentacles. Identify the type of reproduction the marine biologist should use to develop the new coral and explain why this type of reproduction is preferable.

Answers

Answer:

Sexual reproduction.

Explanation:

Sexual type of reproduction used by the marine biologist in order to develop the new coral because variations in an organisms only be done with sexual reproduction. For producing new type of coral, the type of corals should be fused together in order to gain the desire characters in the organisms. So if the marine biologist want coral polyps with large stinging tentacles, sexual reproduction is the only way. From asexual reproduction, the offspring produce identical to parents so that's why we can't use asexual reproduction.

blood enters on the left side of the heart through the_____ and enters the left atrium. Then passes through the_____ to enter the left ventricle 

Answers

Blood enters on the left side of the heart through the pulmonary veins and enters the left atrium. Then passes to the mitral(bicuspid valve) to enter the left ventricle.

Blood is a fluid component of the circulatory system that is very vital for transporting oxygen and nutrients in the body system. It comprises cells suspended in plasma.

The correct answers for the blanks are:

Blank 1: Pulmonary veins

Blank 2: Bicuspid valve

The blanks can be explained as:

The left side of the heart has an atrium that gets the oxygenated blood from the lungs through the pulmonary veins.

Oxygenated blood from the left atrium flows to the left ventricle.

Blood from the left ventricle flows to the aorta that distributes the oxygenated blood to the body parts.

As a star goes through this cycle their _____ changes.

A - luminosity
B - brightness
C - all of these
D - temperature

Answers

Answer:

option C. all of these.

Explanation:

The main sequence period is when a star will experience the majority of its life. Helium is currently being created via nuclear fusion from hydrogen. Thus, option C is correct.

What is a complete cycle of a particular star?

The main sequence phase, which our Sun is in, will be entered by the star if it is large enough to fuse hydrogen atoms into helium.

The mass of a star determines its life span. The life cycle of an object decreases with increasing mass.

The amount of substance present in a star's nebula, the enormous cloud of gas and dust from which it emerged, determines the star's mass.

The temperature and pressure rise when the material compresses, just as they do during formation. The freshly created heat briefly overcomes the effect of gravity, pushing the star's outer layers outward.

Therefore, As a star goes through this cycle their luminosity, brightness, temperature changes.

Cytokinesis, Interphase, Mitosis

Mitosis, Cytokinesis, Interphase

Interphase, Mitosis, Cytokinesis

Answers

Answer:

my best guess would be

Interphase, Mitosis, Cytokinesis

Explanation:

Interphase - stage where the cell prepares for Mitosis. During this stage the cell grows and replicates DNA.

Mitosis - part where the chromosomes are separated and are separated into 2 nuclei.

Cytokinesis - part where cells officially splits into two daughter cells.

Cell cycles are events that involve various series of steps for the cell to grow. It follows the order of interphase, mitosis, and cytokinesis. Thus, option D is correct.

What is the cell cycle?

The cell cycle is an important part of the growth and cell division of the eukaryotic cell. It includes interphase comprising the G₁, S (synthesis/replication), and G₂ phase, mitotic phase, followed by cytokinesis and G₀ phase.

The cell spends the majority of its time in interphase where the genetic material undergoes preparations and gets duplicated for the further process. In mitotic division the actual division of the organelles and the nucleic acid takes place.

Mitosis is followed by cytokinesis where the cytoplasm of the cell gets separated to form two daughter cells after the telophase stage. The cell then undergoes the G₀ phase which is the quiescent stage of the cell division where no cell division occurs.

Therefore, option D. interphase, mitosis, and cytokinesis are the correct order of the cell cycle.

In the days since she and her family had sailed away from Germany and the refugee camp, Liisi had spent many hours staring out at the ocean waves from the deck. Somehow, in the back of her mind, she had always believed they would return home to Estonia after the war. Yet, every time she had mentioned this to her parents, they just frowned and changed the subject. After they had escaped the Russians and fled to Germany, there had been no real home for them except the cramped apartment in the little German town of Geislingen where the U.S. Army housed Estonian refugees. Liisi had made good friends thereher Girl Scout troop of five had been inseparablebut now they were all scattered to the winds. Two of the girls had stayed in Germany, and the other two were going to Canada. Here she was all alone sailing to America. Feeling mighty lonely, Liisi reached into the inside pocket of her coat and pulled out a photograph. On it was her Girl Scout troop, all dressed in traditional Estonian costumes for a dance they had organized at the refugee camp. The dress Liisi wore was too small, as she had worn it back in Tallinn when she was younger. Liisi ran her thumb over the image of herself and closed her eyes as she remembered. "Liisi, hold still while I button your dress!" Her mother scolded. But Liisi was so eager to join the other kids in Tallinn's town square, she could not stop moving. At 10, she was just old enough to join in the folk dances as the city celebrated JaanipevJohn's Day, or Midsummer's Eve. The June 23 festival always made her giddy with delight, and as her mother finally released her, she gave her a swift hug and flew out the door. The square was just a few blocks away, and Liisi could hear the cheers of the crowd as she raced down the cobblestone streets. As she rounded the last corner and entered the square, the dancing had already begun. She was so glad she had paid attention when her mom taught her the traditional steps. Making her way to the front of the crowd, Liisi's school friends waved to her. She caught up to them just as the band started playing, and they arranged themselves in a line for the next dance. At that moment, Liisi could not imagine ever living anywhere else. The wind had picked up, and the ocean spray woke Liisi from her reverie. A tear had made its way down her cheek, and she wiped it away before replacing the photo in her pocket. "That was then," she told herself sternly and pushed those other thoughts away. Then, she turned her back to the ocean as if to leave her entire past behind her and went to find her parents.1Select the correct answer.How does Liisi's cultural background affect her perception of the photograph?A.
