Answer:
D
Explanation:
The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.
(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.
(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.
(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.
(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.

What did you include in your response? Check all of the boxes that apply. The Abert's squirrel is found on the south rim of the grand canyon and surrounding states. The Kaibab squirrel can only be found at the north rim of the canyon. Scientists believe they were separated by plateau erosion that separated the forests of the Grand Canyon, isolating the Kaibab population of squirrels.
Answer:
The completed question is
Two animals that can be found at the Grand Canyon include the Abert’s and Kaibab squirrels. The Abert’s squirrel is found at the south rim of the canyon and in a few surrounding states. The Kaibab squirrel, however, can only be found at the canyon’s north rim, mainly on the Kaibab Plateau. The Kaibab squirrel is not found anywhere else in the world. Scientists believe that the squirrels are actually closely related and have developed separately as a result of geographic isolation. It is possible that the squirrels were separated by plateau erosion that separated the forests and isolated the Kaibab population. Some scientists are studying if the squirrels are now two separate species or if the Kaibab squirrel is simply a subspecies of the Abert’s squirrel. Separate species are unable to reproduce with each other. Which evidence would be used to support the claim that the squirrels are two separate species?
a.The Abert’s squirrel is found at the south rim of the canyon, but the Kaibab squirrel is found at the north rim of the canyon.
b.Geologists prove that plateau erosion is the main cause of forest separation in the region.
c.Scientists observe that Abert’s squirrels are slightly larger and have bushier tails than Kaibab squirrels do.
d.When placed together in pairs for study, no pair of Abert’s squirrel and Kaibab squirrel result in offspring.
Explanation:
Base on the scenario been described in the question, the correct answer should be D.)When placed together in pairs for study, no pair of Abert’s squirrel and Kaibab squirrel result in offspring.

Both plant and animal cells have a cell membrane. Describe the structure and function of the cell membrane.Ambas células, animal y vegetal, tienen membrana celular. Describe la estructura y función de la membrana celular.
Answer:
Explanation:
Similar to a guard at the outside of a club, deciding who should be allowed in and who to keep out, the cell membrane is semi-permeable, regulating the movement of substances in and out of the cell with the help of protein channels.
The cell membrane is a double layer of lipids (fats) and proteins that surround a cell and separates the cytoplasm/ organelles from its surrounding environment.
The cell membrane is present in plant and animal cells. It is the outermost protective layer of a cell.
What is a cell membrane?All cells' interiors are protected from the outside world by a biological membrane called the cell membrane. It is also known as the plasma membrane.
The phospholipid bilayer, which creates a permanent barrier between two aqueous compartments, is the membrane's basic structural component. These compartments are the inside and exterior of the cell in the case of the plasma membrane.
Identification, communication, control of solute exchange across the membrane, metabolic activities, active transport, absorption, and isolation of the cytoplasm from the surrounding environment are the primary roles of the plasma membrane.

9. Do you think that squid have the same type of body organization that humans do? (i.e. cells form tissues
which form organs which form systems) Why or why not?
Answer:
No
Explanation:
They are mollusks
No, the squid have the same type of body organization that humans do i.e. cells form tissues which form organs which form systems as well as unicellular and multicellular organisms.
What is difference between unicellular and multicellular organisms?The main difference between the unicellular reproduce organisms in other hand multicellular-repairs dead or damaged cells. They both help develop and grow in the multicellular this organism has been made up of 2 or more cell they can be made up to trillion if cells, it is much more complex than the unicellular. They reproduce asexually and the cells cannot live outside the organism, they perform specialized functions an example the nerves.
Cell division in unicellular organisms is important for reproduction. Unicellular cell division used for single-celled organism. Cell division in unicellular organisms is used for the reproduction of an organism.
The importance of cell division in multicellular organisms is the development and replacement of damaged and dead cells. Cell division is important for tissue growth and cell maintenance.
Therefore,No, the squid have the same type of body organization that humans do i.e. cells form tissues which form organs which form systems.

An invasive species is an organism that’s not native to a particular ecosystem but ends up invading the region. The populations of invasive species can rise sharply, in part because the species may not have natural predators to control their populations.
The graph shows the population of an invasive tree species spreading through a region. This tree has an earlier reproduction and growing season than many of the native trees. Give three examples of how this tree could affect competition with the native species of plants and animals in the forest.
Answer:
The early reproduction and growing season indicates that these trees will sprout sooner than many native trees. Because all trees need space to grow, the invasive tree species can reduce available space for native species to grow.
As the trees grow, they could limit sunlight availability for other species of trees and plants in the area.
Some plant-eating animals may rely specifically on native tree species for food. If the invading tree species reduces the supply of the native tree species, competition among the animals may increase.
Explanation:
This is the exact answer from edmentum, so you might wanna change it a bit. :)
These trees will likely germinate earlier than many native trees because of their early reproduction and growing season.
What is Invasive species?All trees require area to grow, thus invading tree species may make less room for native species to spread out. As the trees develop, they may reduce the amount of sunlight that is available to nearby tree and plant species.
Some animals that consume plants might only consume local tree species. Competition between the animals may worsen if the invasive tree species lowers the availability of the native tree species.
Animals or plants that are invasive are those from another part of the planet that don't belong in their new habitat. Ship ballast water, an unintentional release, and individuals are the most common ways that they are introduced to an area.
Therefore, These trees will likely germinate earlier than many native trees because of their early reproduction and growing season.

How did Alexander Fleming contribute to Science?
Answer:
Discovered penicillin
Explanation:
Alexander Fleming accidentally discovered penicillin in 1928. He left dirty petri dishes in his laboratory. When he did clean them, he discovered a mold growth, and around this mold, no bacteria were present. There were bacteria in other regions, but none around the growth. He then knew that he discovered an antibiotic: penicillin.
He received the Nobel Prize in Physiology or Medicine in 1945 for his findings. Today, penicillin is used to fight bacterial infections such as pneumonia.

A) oil and garbage
B) mercury and lead
C) herbicides and pesticides
D) viruses and bacteria
Answer:
C
Explanation:
People use herbicides to keep bugs and other things off of plants so when it rains, that can wash off into the ground and thus into our food, our water sources, etc.
The pollutants are most likely released into bodies of water by agriculture are herbicides and pesticides.
How do pesticides work?
Pesticides act in the control and proliferation of pests, weeds and in the fight against possible diseases associated with the cultivation of certain products. They are composed of substances capable of acting on the biological activity of living beings that are in agricultural crops.
The food contamination, river pollution, soil erosion and desertification, intoxication and death of farmers and extinction of animal species, are some of the most serious consequences of industrial chemical agriculture and the indiscriminate use of pesticides, widely stimulated in the last 25 years.

King penguins live on or near Antartica. The females lay one egg at a time with an incubation period of more than 50 days. The female and male parent take turns carrying the egg to keep it warm and protected while the other parent returns to the sea to feed. How is this reproductive strategy similar to other examples you have learned about? How is it different?
Answer:
Sharing of responsibility or division of labor.
Explanation:
This method of reproductive strategy is actually or typically different to most of the ones I am conversant with. For example, when most animals are going through incubation period, especially the birds, it is the only female that carries out this process, and it will leave the place of incubation when it needs to feed. In other group of animals like reptiles, the female will lay eggs in a dug pit or land, lay its eggs and cover it up with sand which will eventually incubate the eggs.
But in this aspect, the incubation involved the male and the female, which is totally different from what I knew before.
The reproductive strategy of Penguins living in Antarctica is different from other.
King penguins live on or near AntarcticaPenguins have different reproductive strategies than others as they share the responsibility of bringing their offspring.
The female and male Penguins take turns holding the egg to keep it warm and covered while the other parent returns to the sea to find food.
Female birds lay eggs in the nest and keep warm during the incubation period until the eggs hatch.

I guess nitrogen cycle since rhizobium plays an important role in nitrogen cycle and it lives on the root nodules of leguminous plants in the soil.
The nitrogen cycle is VERY dependent on the processes carried out by soil bacteria.
What do you mean by nitrogen cycle?The nitrogen cycle is a biogeochemical cycle in which nitrogen changes into several chemical forms as it circulates between atmospheric, terrestrial and marine ecosystems. Nitrogen transformation can occur through both biological and physical processes.
The nitrogen cycle is a repeated cycle of processes in which nitrogen passes through living and non-living things: the atmosphere, soil, water, plants, animals and bacteria.
The nitrogen cycle is important because nitrogen is an essential nutrient for life on Earth. Nitrogen is an important component of amino acids, the building blocks of proteins, and nucleic acids, the building blocks of genetic material.

Explain why a pocket mouses color influencs it’s fitness. Remember that fitness is defined by an organisms ability to survive and produce offspring.
Answer:
The pocket mouse is generally found in rocky outcrops in the deserts of the southwestern United States and Mexico.
Though the fitness of an organisms helps them to survive and produce offspring but the color of pocket mouse influences its fitness because the color of mouse helps them to survive from the predators. The rock pocket mouse having light color fur blend with dark sand and blend with the sand which increases their chances of survival and the allele for dark fur will be passed on to their offspring.
Hence, color of pocket mouse or rock pocket mouse influences its fitness.
