2. Discuss why a four chambered heart is more efficient than a two chambered heart in delivering oxygenated blood to the various body parts. What evolutionary changes in the lifestyles of organisms selected for the evolution of the four chambered heart?

Answers

As organisms became more active, a four-chambered heart was selected for because of its ability to separate oxygenated and deoxygenated blood.

Why is a four-chambered more efficient in oxygen delivery than a two-chambered heart?

A four-chambered heart is a heart consisting of four chambers, namely;

upper ventricle lower ventricle upper atrium and lower atrium

A four-chambered heart is more efficient in oxygen delivery than a two-chambered heart because it does not allow for mixing of oxygenated and deoxygenated blood.

A more active lifestyle by organisms and larger body size selected for a four-chambered heart in organisms.

Therefore, the efficiency of a four-chambered heart is in it's ability to separate oxygenated and deoxygenated blood.

Answers

The plant is made up of root and shoot structures that contain parts that enable the plant to grow and manufacture its food.

The structure and function of plants

The structure of plants is made up of tissues such as:

phloemstomaxylemguard cellsdermalground andvascular.

The three characteristics that all species being to the plant kingdom have in common are:

They are non-motile,

They make their food hence are called autographs; and

Their cell walls are made sturdy by a material called cellulose

The tropical plants have more stomata than the desert plants. This helps the desert plants to reduce water loss.

Some defects occur when there is damage to the vascular tissues such as the xylem( plant will not be able to transport water from the soil through roots to leaves) and phloem (nutrients produced during photosynthesis will not be able to reach every part of the plant body).

The dermal tissue of plants and the human skin performs protective roles to the underlying tissue organs.

A plant won't be able to survive because it won't absorb water and nutrients from the soil and transport it upwards to all the parts of the plant.

Flowering reproduction in plants takes place through the following steps:

Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.

Flowers benefit other organisms in our environment by creating more carbon dioxide-absorbing and oxygen-radiating plants.

The flowers contain male reproductive organs called stamens and female reproductive organs called pistils.

The process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.

Most flowers are bright in color because they are like advertisement signs for pollinators.

A female mosquito can produce 50-500 offspring in a two-week period of time. This rapid reproduction can also result in fast
evolution for this small insect species. For example, pesticide resistance occurs rapidly in insects, including mosquitos. Insecticides
that were once effective at eradicating mosquito populations are no longer effective. Which component of natural selection is

A)
Mosquitoes pass only advantageous traits on to their offspring during
reproduction. This ensures increased survival and reproduction.
B)
Mosquitos produce more offspring than can survive in their lifetime.
Offspring are varied genetically, with differential survival and reproduction.
Mosquitoes that learn to avoid pesticide exposure can pass that

Legend has it that a Philadelphia seamstress named Betsy Ross was hired by George Washington himself to create this flag. There is no evidence that this legend is true, and no one knows for certain who made the first flag, which had 13 stars and 13 stripes. However, we know for a fact that the first flag to have 50 starsthe one we have todaywas designed by a high school student. In 1958, Bob Heft was a 17-year-old student at Lancaster High School in Ohio. At that time, the United States had only 48 states but was on the verge of accepting two more: Alaska and Hawaii. The U.S. flag at the time had six neat rows of eight stars each. What would be the best way to add two more stars while keeping the arrangement neat and orderly? This was the question that Bobs history teacher posed to the class. The teacher gave the students an assignment: design a flag with 50 stars. Bob spent hours in the attic of his house, cutting up a 48-star flag and rearranging the stars until they fit just right. He was pleased with his solution to the problem, but his teacher found it less than perfect and gave him a B minus. Outraged, Bob told his teacher that he was going to send his design to his member of Congress, Walter Moeller. His teacher replied that if Bobs design was accepted as the new flag, he would be more than happy to change the grade to an A. A year later, Bob had graduated and was working as a draftsman when he received a call at work. He never would have imagined a call from President Eisenhowerbut that's who it was! Now that Alaska and Hawaii had been admitted as states, Congressman Moeller had succeeded in having Bob's design chosen as the new U.S. flag. Bob Heft was invited to Washington, D.C., for a ceremony during which his design was officially adopted as the new flag of the United States.Which statement best describes the authors viewpoint toward Bob Heft in A Flag with 50 Stars?Bob should not have contacted a member of Congress about a trivial matter.Bob was not a very good student at Lancaster High School.Bob should not have spent so much time on his project.Bob's grade did not reflect the outcome of the story.
