The table and graph are attached
1. Find the graph paper in your kit and graph your results by putting the generation number along the x-axis and the number of bears along the y-axis. When drawing the lines, use a different color to represent each type of bear. (Make sure to indicate which color goes with which type of bear.)
2. Summarize the trends you see in each population from each generation.
a. Dark bears—
b. Light bears—
3. Explain how this experiment demonstrated natural selection.
Answers
From the data, it is concluded that the black bear has a greater number of offspring than the light bear, as the environment favors the darker bear over the white bear. This explains why natural selection favors the dark bear.
White bears, also known as polar bears, are adapted to live in the harsh environment of the Arctic region. They have a thick layer of insulating fur, large paws that help them walk on snow, and a streamlined body that helps them swim through icy water to hunt for food. Black bears, on the other hand, are found in a variety of environments, including forests, mountains, and swamps. They have a shaggy coat that helps them stay warm in cooler climates, and they can climb trees to avoid danger.

Answers
Answer:
True
Explanation:
Osmosis refers to the movement of water particles from a region of low concentration to a region of high concentration.
When sprinkled with sugar, a dish of sliced fruit will form its own juice. This is because the sprinkled sugar has a higher concentration which explains why water moves out from the fruit with a lower concentration to dilute the sugar which has a higher concentration.

Answers
Functional genomic approaches are favored over biochemical approaches to determine the function of a gene for all these reasons, except "biochemical approaches are more expensive." The correct option is B.
Functional genomic approaches are favored over biochemical approaches to determine the function of a gene for several reasons.
One of the main advantages of functional genomic approaches is that they can bypass the need to isolate individual proteins, which can be time-consuming and technically challenging.
Instead, these approaches use computational methods to identify gene function from DNA sequence alone, allowing for more efficient and high-throughput analysis of gene function.
Another advantage of functional genomic approaches is their accuracy.
By examining the effects of gene expression on cellular processes, these approaches can provide a more comprehensive understanding of gene function than biochemical approaches that focus on the properties of individual proteins.
However, one of the reasons that functional genomic approaches are preferred over biochemical approaches is not that they are more cost-effective.
In fact, functional genomic approaches can be more expensive than biochemical approaches, particularly if they involve the use of high-throughput sequencing technologies or the development of new computational methods.
Nonetheless, the benefits of functional genomic approaches in terms of speed, accuracy, and comprehensiveness often outweigh the increased cost. Therefore, the correct answer is B.

Our Current Eon is divided into 3 Eras. List them from oldest to youngest.
Answers
The Phanerozoic, the eon of visible life, is divided into three broad periods, primarily on the basis of characteristic assemblages of life forms: the Paleozoic (541 million to 252 million years ago), the Mesozoic ( 252 million to 66 million years ago) and Cenozoic (66 million years ago to present).
What is our Current Eon?Phanerozoic is the geological period spanning about 541 million years from the end of the Proterozoic (which began about 2.5 billion years ago) to the present day. Although life clearly arose at some point, probably quite early, in the Archean eon (which lasted 4 billion to 2.5 billion years ago), it was not until the Phanerozoic that the rapid expansion and evolution of forms occurred, filling the various ecological niches available. The key to this great Phanerozoic expansion seems to lie in the evolution of plants capable of carrying out the process of photosynthesis and thus releasing free oxygen into the atmosphere.

Understanding gas and vapours in a work setting is incredibly important for workplace safety. Gas and vapours can contain noxious substances that, if exposed to, can lead to serious injury or health implications.
In order to prevent such accidents, employers must perform risk assessments in order to assess and identify any areas of risk and put in place control measures to limit them. If gas and vapours are used onsite, then suitable ventilation and extraction systems should be in place.
Employers should also ensure that their staff are aware of the potential risks associated with such substances and provide adequate training and instruction in how to work safely. Finally, employers should also check that any necessary personal protective equipment is provided and communications are in place to be able to notify relevant emergancy responders in case of an accident.

What is the super additive effect of Multisensory integration sometimes called?
Answers
The super additive effect of multisensory integration, sometimes called "superadditivity," refers to the phenomenon where the combined response to multiple sensory stimuli is greater than the sum of the individual responses to each stimulus.
This effect occurs as a result of the brain integrating information from different sensory modalities, such as sight, hearing, and touch, to create a more comprehensive and accurate representation of the environment. In multisensory integration, the brain processes information from multiple senses simultaneously, leading to enhanced perception and more efficient decision-making. The super additive effect can be observed when the simultaneous presentation of stimuli from different modalities results in a response that is stronger than the sum of the responses to each stimulus presented independently. For example, consider a scenario where an individual perceives an event through both visual and auditory cues. When the cues are combined, the person may have a faster and more accurate reaction than when relying on either cue alone. This enhanced response is due to the super additive effect of multisensory integration.
In summary, the super additive effect, or superadditivity, is a key aspect of multisensory integration where the combined response to multiple sensory inputs is greater than the sum of individual responses. This phenomenon allows the brain to process information more effectively, resulting in improved perception and decision-making.

What is the most potent stimulus for a positive feedback loop that results in the release of bile by the liver?.
Answers
(c) secretin is the most potent stimulus for a positive feedback loop that results in the release of bile by the liver.
Fats are mechanically broken down in the small intestine by the emulsifier substance known as bile. In order for digestive lipases to carry out their chemical digestion of fats effectively, fats must dissolve in order to expand their surface area.
The most effective trigger for the positive feedback loop that causes the liver to secrete bile is secretin.
A hormone called secretin is created by the small intestine's enteroendocrine cells in response to the stomach's chyme. In order to create and release bile into the gallbladder, secretin activates liver hepatocytes.

Prokaryotes are usually unicellular organisms, examples are bacteria. One key feature of prokaryotic cell is a piece of circular, double stranded DNA which is usually found in the cell.
hope it helps : )
Explanation:
The cells lacking membrane-bound organelles and well-defined nuclear regions are called prokaryotes.
What are prokaryotes?
Prokaryotes are creatures without a nucleus or other organelles in their cells. Bacteria and archaea, two separate groupings of prokaryotes with allegedly independent evolutionary histories, are separated.
The majority of prokaryotes are tiny, single-celled creatures with a straightforward structure. Prokaryotic cells lack intrinsic membrane-bound organelles in their cytoplasm while being surrounded by a plasma membrane. Prokaryotes differ from eukaryotes, another type of creature, in that they lack a nucleus and other membrane-bound organelles.
One circular DNA molecule, or chromosome, makes up the majority of the genetic material carried by prokaryotes. Prokaryotes have a nucleoid in the center of the cell that houses the DNA but is not protected by a nuclear membrane. In addition to chromosomal DNA, many prokaryotes also possess smaller, circular DNA molecules known as plasmids, which can provide genetic benefits in particular situations.
Therefore, the cells lacking a defined nucleus and organelles are called prokaryotes.

explain the effect of surface area-to-volume ratios on the exchange of materials between cells or organisms and the environment.
Answers
Smaller cells typically have a higher surface area-to-volume ratio and more efficient exchange of materials with the environment.
As cells increase in volume, the relative surface place decreases and the call for for internal resources increases.
Cells with larger surface-to-quantity ratios are able to change materials extra efficaciously. The smaller a cell, the bigger its surface-to-volume ratio. As a cellular grows larger, the volume increases faster than the surface region.
every cellular has a limit of floor vicinity to quantity ratio to make sure that the trade of resources and waste occurs quickly sufficient for the cell to survive. If cells had been too big, diffusion would take an extremely long time, and a cell may want to die from starvation or poison itself with its wastes.
If the floor location to volume ratio is low, the efficiency of a cell is reduced. As a cellular will increase in size, it turns into tougher to efficaciously transport materials into and out of the cell.
