Explain why proteins are considered polymers but lipids are not

Answers

Answer 1

Answer:

Answer:

Polymers are made from a chain of one similar subunit bound together in sequence. Proteins are made from polypepetide chains which are sequences of amino acid subunits. Another example of polymer is DNA and RNA made of nucleic acid subunits.

However, lipids do not have one similar subunit but rather variable ways in which the lipid chains can form. For example phospholipid unit is made of a phosphate molecule bound to a fatty acid chain and glycerol. A triglyceride is a subunit of glycerol bound to three fatty acids chains. Cholesterol is also considered a lipid but is made of carbon rings rather than chains. Lipids therefore cannot be referred to as a polymer.

Answers

So all we know is that the student stated something ("if plants are added to an indoor environment the air quality will improve "). This is only a statement - it's not a test whether this statement is true yet.

So the correct answer is: it is a hypothesis.

Hypothesis!!!!!!!! Is correct.

Advantages and disadvantages of indoor production broiler? And the barriers to expanding the free-range segment of the broiler industry. The answer focus on consumer preferences , product quality bird physiology nutrition and environmental factor

Answers

Answer:

Explanation:

The benefits of indoor production (for broilers) include regulated settings, reduced risk of illness, and optimal development circumstances. Optimal temperature, humidity, and illumination management improve feed efficiency and year-round output.

Limitations in space might affect the quality of the meat and the wellbeing of the birds in indoor production (broilers). Bird quality can be impacted by poor air quality, stress from overpopulation, and other factors. There are also issues with the environment and possible antibiotic usage.

Consumer preferences, unpredictable product quality, slower growth rates, greater feed requirements, weather-related dangers, and regulatory obstacles all work against the expansion of free-range broiler production. Addressing quality, welfare, sustainability, and public awareness are necessary to strike a balance amongst these aspects.

Advantages of indoor production for broilers include better control over environmental factors such as temperature, lighting, and ventilation, which can lead to improved bird growth and feed conversion. Indoor production also allows for year-round production regardless of weather conditions. Additionally, it can provide protection from predators and diseases.

Disadvantages of indoor production include potential concerns about animal welfare, as broilers may be confined to limited spaces. There may also be higher risks of disease transmission due to close proximity of birds. Indoor production systems may require more energy for heating, cooling, and lighting, contributing to environmental impact.

Barriers to expanding the free-range segment of the broiler industry include consumer preferences, as some consumers may prefer the affordability and convenience of conventionally raised broilers. Product quality can also be a challenge, as free-range broilers may have different growth rates and muscle development compared to conventionally raised broilers. Bird physiology and nutrition need to be carefully managed to ensure proper growth and health in free-range systems. Lastly, environmental factors such as land availability and potential exposure to predators can limit the expansion of free-range broiler production.

Why is it important for signal transduction systems to trigger a rapid response within a cell and be able to be shut down quickly?

Answers

-All signal transduction cascades are shut down immediately so as to prevent the cell from mounting a response.

-Cells are unable to respond quickly to hormones, and therefore signal transduction cascades always occur over a long time.

-Cells have to be able to function alone, because they are unable to work together in a coordinated fashion.

-Cells often have to respond very quickly to changes in their internal and external environments.
