Which three statements accurately describe the blood buffering system in humans?

Bacteria can be genetically engineered to produce human or sea anemone proteins for several reasons. One of the primary reasons is that these proteins may have important medical or industrial applications.

For example, insulin is a hormone that regulates blood sugar levels in humans and is used to treat diabetes. Similarly, red fluorescent protein (RFP) from sea anemones can be used as a molecular tag to track the movement of specific molecules in cells and tissues.

Producing these proteins in bacteria can be more efficient and cost-effective than producing them in humans or sea anemones. Bacteria can be grown rapidly in large quantities and are genetically tractable, meaning that specific genes can be manipulated to optimize protein production. Furthermore, the use of bacteria in the production of recombinant proteins can reduce the risk of contamination with pathogens that may be present in animal or plant cells.

Answer:

To form a wide range of compounds with other elements

Explanation:

The ability of carbon to gain four more electrons allows this chemical specie to form a wide range of compounds.

When carbon gains four electrons, it becomes isoelectronic with neon and then becomes a stable compound or molecule as it combines with other atoms.

This leads to the proliferation of carbon compounds that we find in nature. Carbon can easily for covalent compounds with other compounds also.

The standard plate count approach is better for assessing food and water safety since it counts only live bacteria. The classic plate count method includes inoculating a diluted sample onto an agar medium and letting the bacteria develop into visible colonies.

Each colony is a live, potentially harmful bacterium. Counting colonies estimates the sample's live bacteria. For sample safety, this approach counts live bacteria. Living bacteria can grow and reproduce, making them most likely to cause foodborne or waterborne infections. The standard plate count approach better estimates sample risk by counting only live bacteria.

Microscopic examination or DNA-based approaches may count living and dead bacteria or non-viable cells. These approaches may overestimate bacterial density and safety by not distinguishing viable from non-viable bacteria.

Thus, the standard plate count method targets living bacteria, making it easier to assess food or water sample safety.

Over the past century, American farming has changed dramatically. Crops with long histories like tobacco are still prevalent throughout the South, while many farmers across the country are now exploring the possibility of a thriving hemp market. Every state has a rich farming history, from the tomatoes made in New Jersey, to the sheep used for wool production in Wyoming. Currently, some farms are looking to new technology to maintain their blue-collar livelihood, while others have decided to shut down shop, unable to keep up with fluctuating markets, export worries, and other daily concerns of America’s farmers. Those aspects and more are detailed in Stacker’s dive into how American farming over the past 100 years.

Stacker compiled a list comparing agriculture in each state over the last 100 years using data from the 1920 Agriculture Census, and most recent data as of Feb. 28, 2020, from the 2019 Census State Agriculture Summaries. The 1920 Census figures were released in 1922, and even include some data for areas of the U.S. that weren’t even technically states yet, like Alaska and Hawaii (where bees were widely harvested to make honey and waxes).

While American farming has certainly expanded and increased its value since 1920, there were almost three times as many farms 100 years ago than there are today—in 1920 there were 6.5 million farms, while 2020 estimates come in at two million. Within each slide, we discuss the essence of a state’s agricultural economy then and now, significant changes in crops, legislation, and industry size, and other tidbits like where some of the earliest immigrant farmers arrived from.

Explanation:

In the experiment, they painted yellow caterpillars green and placed them in a green environment amongst naturally green caterpillars. However, the paint only camouflaged the caterpillars into the environment, not reset their genes. So, the offspring of yellow caterpillars would most likely come out yellow (or green if it's in their genes), resulting in the yellow caterpillar offspring to be picked off more easily than the offspring of the green caterpillars.

The similarity between insulin extracted from cattle and human insulin is an example of evidence for evolution gained from comparative anatomy or comparative genomics.

Comparative anatomy involves the study of anatomical structures across different species to identify similarities and differences. In this case, the similarity between cattle insulin and human insulin suggests a common evolutionary origin. The fact that cattle insulin can effectively treat human diabetics indicates that the protein structure and function have been conserved over evolutionary time.

Comparative genomics involves comparing the genetic sequences of different organisms to identify similarities and differences. By comparing the genetic sequences of cattle and humans, scientists can analyze the similarities in the genes responsible for insulin production. The high degree of similarity between the insulin genes in cattle and humans further supports the idea of a shared evolutionary history.

These comparisons provide evidence for the theory of evolution, as they demonstrate the presence of common ancestry and the conservation of genetic and anatomical features across species. They indicate that living organisms have evolved through gradual changes over time, leading to the diversification of species while maintaining certain fundamental similarities.

Explanation:

The amount of energy used at rest to maintain normal bodily functioning is called the Basal Metabolic Rate (BMR).

Basal metabolic rate refers to the number of calories or energy expended by an individual while at complete rest, in a post-absorptive state (meaning they have not eaten for at least 12 hours), and in a thermoneutral environment (maintaining a stable body temperature).

The basal metabolic rate encompasses the energy required for vital processes such as breathing, circulating blood, regulating body temperature, and maintaining cellular function. These essential functions involve processes like respiration, heartbeats, organ function, protein synthesis, and maintenance of ion gradients across cell membranes.

The BMR varies from person to person and is influenced by factors such as age, sex, body composition, and genetics. It is typically measured in calories per day or kilojoules per day.

While the BMR represents the energy expenditure at rest, it should be noted that additional energy is required for physical activity, digestion of food, and other voluntary activities throughout the day.

Memory B cells are a type of B lymphocyte developed in response to an antigen exposure, such as a virus. They are able to recognize different virus antigens and quickly mobilize to directly attack them, making them essential components of immunity.

If a person has memory B cells against an antigen on the measles virus, they have a greater chance of fighting off a measles infection because they can quickly recognize and attack the virus. Memory B cells are generated during primary infection and remain in the body afterwards, so even after the pathogen has been cleared from the body, the memory B cells will still be present and ready to respond to any subsequent infections.

This allows them to respond more quickly and efficiently to the same infection in the future, protecting the person from becoming reinfected.

Increases the likelihood of their survival by allowing them to respond to changes in their environment and adapt to different conditions.

Prokaryote , such as bacteria, inhabit diverse environments and face varying conditions. Being able to alter patterns of gene expression provides them with a mechanism to respond to these changing environments. By regulating which genes are expressed and when, prokaryotes can adjust their physiological and metabolic processes accordingly. This flexibility allows them to adapt to different nutrient availability, temperature shifts, pH changes, and other environmental factors.

For example, if a prokaryote encounters a limited nutrient source, it can upregulate genes involved in nutrient acquisition and metabolism to optimize its chances of survival. On the other hand, when exposed to stressors like toxins or extreme temperatures, prokaryotes can activate stress response genes that help protect them and promote survival under these adverse conditions.

Overall, the ability to alter gene expression patterns enables prokaryotes to fine-tune their cellular processes, optimize resource utilization, and respond effectively to changing environmental conditions. This flexibility in gene expression increases their likelihood of survival in different habitats and enhances their overall adaptability as a species.
