The method used over IEEE 802.11 WLANs to limit data collisions caused by a hidden node is the b. four-frame exchange protocol.

The four frame exchange protocol, also known as the Request to Send/Clear to Send (RTS/CTS) mechanism, helps mitigate the hidden node problem by introducing an additional control frame exchange process prior to actual data transmission. In this method, the sender issues a Request to Send (RTS) frame, which includes the intended duration of data transmission. The receiver, upon receiving the RTS, responds with a Clear to Send (CTS) frame, informing other stations in the network to refrain from transmitting data for the specified duration. Once the CTS is acknowledged, the sender proceeds with data transmission. Finally, the receiver sends an acknowledgment (ACK) frame to confirm successful receipt of data.

By using the four-frame exchange protocol, the communication between the sender and receiver is established and maintained, preventing potential data collisions caused by hidden nodes that might not be directly aware of the ongoing communication. This mechanism enhances the overall efficiency and reliability of IEEE 802.11 WLANs in handling the hidden node problem.

Answer:

Organisms are buried under the sediment.

Explanation:

Organisms are buried under sediment is the first step in the process during the formation of molded fossils.

Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. The mineralized impression of the organism left in the sediment is called a mold.

Moreover, cast and mold are a type of fossilization where the physical characteristics of organisms are impressed onto rocks, especially coarse porous rocks such as sandstones.

A mold fossil is a complete replica of the shell, formed from when the shell was filled in and surrounded by sediment.

Gene duplication creates genes that are under positive selective pressure, as they provide additional copies of genetic information that can potentially evolve into new functions.

This is because gene duplication allows for mutations to occur on one of the copies without affecting the original function of the other copy. These mutations can lead to new beneficial traits that provide an advantage in the organism's environment.
For example, in the evolution of vertebrates, gene duplication events led to the formation of new genes responsible for the development of eyes, immune systems, and limbs. These new genes allowed organisms to adapt to new environments and exploit new resources. In some cases, the duplicated gene may evolve to perform a new function, such as the evolution of beta-lactoglobulin gene duplication in cows, which created a new protein that is essential for milk production.
Overall, gene duplication allows for the creation of new genetic information that can evolve into new beneficial traits under positive selective pressure. These new traits provide an advantage to organisms in their environment and contribute to the diversity of life on Earth.

Antibiotic C was the most effective in controlling the growth. The 3rd option is the correct one.

Antibiotics are substances that either inhibits the growth of or kill bacteria.

Those that inhibit the growth of bacteria are said to be bacteriostatic while those that kill bacteria are said to be bacteriocidal.

Looking at the four graphs, the only graph in which the number of bacteria decreased perpetually is the 3rd graph. That is the graph in which antibiotic C was added.

Antibiotic B also decreased the growth of the bacteria initially. However, the bacteria resumed normal growth with time.

It seems the bacteria have become resistant to the effects of Antibiotics A and B. With antibiotic resistance, bacteria thrive in the presence of antibiotics. These microbes are able to develop resistance through natural selection.

Thus, the most effective antibiotic from the graphs would be antibiotic C.

North Carolina’s biotech industry is quickly expanding.

Within the state, there are more than 600 life science companies employing 61,000 people at an average salary exceeding $81,000 a year – which is nearly twice the state’s overall private sector wage, according to the North Carolina Biotechnology Center.

In total, life science companies and institutions in North Carolina generate $73 billion in economic activity, which is an increase of 23 percent in two years, and account for 228,259 direct and indirect jobs, says North Carolina Biotechnology Center.

Furthermore, while employment in the nation’s life science industry rose by 7.4 percent from 2001 to 2012, North Carolina’s grew at a surprising 31 percent, even with setbacks from the Great Recession of 2008.

Following closely behind California, North Carolina outpaced life science industry growth in other states, including Texas, New York, Massachusetts and Florida, between 2009-2012, according to the U.S. Bureau of Labor Statistics. In the chart below, North Carolina's life science industry grew 5.2% from 2009 to 2012. While California's life sciences industry increased even more at 5.5% during the same time period, other states such as Pennsylvania and New Jersey actually saw their life sciences sectors shrink by 7% and 7.3%, respectively.

When are the two organisms that share the most common ancestor in the tree 1. the sequence of branching does not necessarily indicate the actual (absolute) ages of the particular species 2. we cannot assume that a taxon on a phylogenetic tree evolved from the taxon next to it (just bc two species are located near each other does not mean the are more clostly related)

“Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors. Two species (B & C) are more closely related to one another than either one is to a third species (A) if, and only if, they share a more recent common ancestor with one another (at Time 2) than they do with the third species (at Time 1).

The type of white blood cells that are primarily involved in fighting off parasitic infections, such as flukes and roundworms, are eosinophils.  the correct answer is A) Eosinophils.

Eosinophils are a type of granulocyte, a category of white blood cells characterized by the presence of granules in their cytoplasm. Eosinophils play a crucial role in the immune response against parasitic infections, particularly helminths (parasitic worms) such as flukes and roundworms.

When parasites invade the body, eosinophils are recruited to the site of infection. They release toxic substances, such as cationic proteins and reactive oxygen species, which are effective in killing and destroying parasites. Eosinophils also have surface receptors that can recognize and bind to components of parasites, facilitating their elimination from the body.

It is true that sprawl can have an adverse effect on the environment by dividing up open space and wildlife habitat.

A defensive manoeuvre used in reaction to specific takedown attempts, usually double- or single-leg takedown attempts, is referred to as a sprawl in martial arts and wrestling. In order to land on the upper back of the opponent attempting the takedown, the sprawl is executed by scooting the legs backwards. Urban sprawl has been linked to rising energy consumption, pollution, and traffic congestion as well as a loss of community identity. Poor water quality has been linked to a number of detrimental health outcomes, such as cancer, kidney illness, and gastrointestinal disorders. Deforestation and the destruction of wildlife habitat are two more negative environmental effects of sprawl in addition to air and water pollution. Urban sprawl, a specific type of urban growth, is a major contributor to many of the problems that cities face today. These issues include the production of greenhouse gases, air pollution, traffic jams, and a lack of affordable housing.

The main differences between the meiotic divisions in a developing sperm and those in a developing ovum are the different timing, number of cells produced and their size.

The main differences between the meiotic divisions in a developing sperm and those in a developing ovum are as follows: Timing: In males, meiotic divisions begin at puberty and continue throughout their life, while in females, they begin before birth but halt in the diplotene phase and only resume after puberty. Number of cells produced: A diploid spermatogonium produces four haploid spermatids, while a diploid oogonium produces only one haploid ovum during meiotic divisions.

Size: The meiotic divisions of spermatogenesis lead to equally sized sperm cells, while in oogenesis, the cytoplasmic division is unequal, leading to one large egg cell and smaller polar bodies that degenerate. Overall, there are significant differences in the timing, number of cells produced and their size between the meiotic divisions in a developing sperm and those in a developing ovum.

Answer:

See the answer below

Explanation:

All living things have certain characteristics. The genetic code carries the directions for inheritance, and offspring usually resemble their parents. With asexual reproduction, offspring have the same traits as their parents. With sexual reproduction, offspring differ from their parents in some ways. Living organisms use energy and materials to grow, develop, and reproduce. These life processes involve a set of chemical reactions called metabolic reactions. Organisms have means of detecting a change in their environment and responding to this stimuli. Most organisms require that their internal environments remain in a fairly constant range, and so they maintain homeostasis. The ability of a group of organisms to change, or evolve, over time is necessary for survival in an ever-changing environment.

Sexual reproduction involves crossing over of genetic materials between non-homologous chromosomes during gamete formation unlike in asexual reproduction. Hence, offspring from sexual reproduction differ from their parents to an extent while those from asexual reproduction are clones of their parents genetically.

Life is generally sustained by chemical processes known as metabolic reactions. Substances are constantly being formed (anabolic) and being broken down (catabolic) within the body of living organisms.

Organisms respond to stimuli in their environment. They are equipped with means to detect changes and act accordingly. Most living organisms are required to maintain a relatively constant internal environment. The process of doing this is known as homeostasis. Organisms need to constantly evolve in order to keep up with ever-changing environment.

Explanation:

Glycolysis and gluconeogenesis are not exact reverse to each other because in glycolysis, glucose is converted into pyruvate, adenosine triphosphate (ATP), NADH, protons i.e. hydrogen ions and water whereas in gluconeogenesis, pyruvate is converted into glucose and glycogen. So due to  the formation of different products of each process we can say that glycolysis is not exact reverse of gluconeogenesis.

An athlete is running a race. The athlete’s body needs energy. Mitochondria in the athlete’s cells supplies the energy for cellular function.

Mitochondria- The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, that are membrane-bound cell organelles. Adenosine triphosphate (ATP), a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).

ATP- A vital "energy molecule" present in all living things is adenosine 5′-triphosphate, also known as ATP and typically written without the 5′-. In particular, it is a coenzyme which transfers energy to the cells by releasing the phosphate groups when it interacts with enzymes like ATP triphosphatase.
