which of the following would not be considered a point source pollution contributor a. an animal feed lot b. cattle on rangeland c. a paper mill d. a slaughterhouse

Answers

Answer 1

Answer: The correct answer should beb. cattle on rangeland

Point source pollution contributors are any pollution contributors that can be pinpointed to a single location, and dispersed cattle on a rangeland is not it. A a paper mill or a feed lot or a slaughter house can easily be pinpointed.

Insulin, a protein that regulates blood sugar levels, is secreted from specializedpancreatic cells.Assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.For each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (Note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)Options:Cytoplasm only, ER --> cytoplasm, ER --> Golgi --> outside cell, cytoplasm --> ER --> outside cell, Golgi --> ER --> outside cell, cytoplasm --> Golgi --> outside cell, nucleus --> cytoplasm, ER --> Golgi --> cytoplasm

The aloe plant has thick, water-filled leaves covered with spikes. The flowers are high on a stalk, so that pollen can be quickly and easily released. What biome is the aloe BEST adapted for? 1. tundra

Answers

Aloe Vera is a native plan in North Africa. It is considered to be a succulent or fat plant which gives it its ability to store large amounts of water in its leaves and roots. This is the reason why this plant grows best in mild to warm climate such as the desert.

White light is a blending of all the colors of visible light.True or False

I believe this is true, since if you use a prism, it becomes a rainbow of light and making the colors of the light visible to the human eye that way.

true...................................

Beetle pollinators of a particular plant are attracted to its flowers' bright orange color. The beetles not only pollinate the flowers but mate while inside of the flowers. A mutant version of the plant with red flowers becomes more common with the passage of time. A particular variant of the beetle prefers the red flowers to the orange flowers. Over time, these two beetle variants diverge from each other to such an extent that interbreeding is no longer possible. What kind of speciation has occurred in this example, and what has driven it? A. Allopatric speciation, ecological isolation.
B. Sympatric speciation, habitat differentiation.
C. Allopatric speciation, behavioral isolation.
D. Sympatric speciation, sexual selection.
E. Sympatric speciation, allopolyploidy.

Answers

Answer:

B. Sympatric speciation, habitat differentiation.

Explanation:

The right answer to our question is B, Sympatric speciation, habitat differentiation.

Edward Bagnall Poulton derived the term sympatric speciation in 1904. It is a mode of speciation, which entails new species emerging from an ancestral species that is still alive and extant. Both the emerging and ancestral species will exist in the same zone.

This speciation is found more in plants. There are different types of these speciations. Habitat differentiation is seen within sympatric speciation. It is found when mutations that exist in the same zone can make use of varying conditions. Allopatric speciation and parapatric speciation are the other types of speciation.

Final answer:

In the given scenario, Sympatric speciation driven by habitat differentiation has occurred. The different 'habitats' are represented by the flower color preferences of the beetle variants, leading them to diverge to the point of becoming distinct species.

Explanation:

The type of speciation that has occurred in the provided scenario is Sympatric speciation, driven by habitat differentiation. In this context, sympatric speciation refers to the process where new species evolve from a single ancestral species while inhabiting the same geographic region. In this case, the 'geographic region' is the color of the flowers. The red and orange flowers represent different 'habitats' for the beetles.

In terms of what has driven this speciation, it is habitat differentiation. This is because even though the beetles are occupying the same general physical area, their 'habitat' in terms of the color of the flowers they prefer has caused a divergence in their mating and, hence, their gene pools. Over time, this leads to the two beetle variants becoming so different that interbreeding is no longer possible, effectively rendering them distinct species.

Which of the following will NOT cause mass extinction?Drastic change in weather
Geological change
Both a and b
None of the above

Answers

Geological change will not cause a mass extinction, because it happens on a too big scale - on the scale of millions of years. During such long time, it is more likely that other causes will influence the survival of extinction of species, such as climate change or environmental disasters, and even if there is a small influence, it would not be significant next to other causes.

Bacteria that are shaped like rods are called?A. cocci
B. spirilli
C. bacilli
D. filamentous

Answers

Bacteria aresingle celled microorganisms. They have a simple cell structure than otherorganisms because they have no nucleus and no cell membrane. Their controlcenter containing the genetic information si contained in a single loop of DNA.They are classified into five groups according to their shape; cocci arespherical, bacilli are rod shaped, spirilla are spiral, vibrios are comma andspirochaetes are corkscrew. They can exist as singe cells in pairs, chains orclusters. Rod shaped bacteria are called bacilli. The answer is letter C.

Final answer:

The term for rod-shaped bacteria is 'bacilli'. This category is a part of the larger classification in microbiology based on bacterial shape, which also includes cocci for spherical bacteria and spirilli for spiral-shaped bacteria.

Explanation:

In the field of Biology, particularly microbiology, bacteria are often categorized based on their shape. For bacteria that are shaped like rods, the term used is bacilli. This contrasts with other shapes, such as cocci (spherical) and spirilli (spiral-shaped). For instance, Bacillus subtilis is a type of rod-shaped bacteria, which demonstrates the morphological type bacilli.

The correct answer is C. bacilli. Bacteria that are shaped like rods are called bacilli. These bacteria have a cylindrical shape and can be found in various environments, such as soil, water, and the human body. Some examples of bacilli include E. coli and Salmonella.

How does natural selection support the theory of evolution?A. Natural selection explains how the changes in life forms that evolve over millions of years take place over shorter periods of time. B.

Darwin hypothesized that there are definite steps to natural selection. Consider the model here. Use the Roman numerals (I - III) to guide you through the steps. Which is an accurate description of Darwin's hypothesized theory of natural selection? A) Sexual reproduction of bacteria cause variation. Some bacteria survive and some do not. Over time all of the bacteria should become extinct. B) In any population, variation exists. Some bacteria are resistant to antibiotics. Most bacteria die, but the bacteria that are resistant survive and reproduce. C) In a population of bacteria that are exposed to antibiotics, some bacteria change their genetic make-up and survive. The new genetic make-up is passed on to offspring. D) There is a change in the environment: an antibiotic is added. Some of the bacteria are capable of changing to the new environment. They survive and reproduce, passing along their favorable traits.
