1,421 Questions

Why is biodiversity important?

It is the biodiversity on Earth that allows (at the moment) for animals, plants and humans to share the planet- if one species is destroyed, several, maybe even hundreds more, may follow.

Biodiversity is important because certain organisms have economic value (such as rainforest plants being made into medicine), they have value to the ecosystem (think of their spot on a food web), and they are a source of natural beauty and recreation.
Sometimes diseases or insects can wipe out a food crop. Having a variety of plants helps prevent widespread dead plants.
Biodiversity is the representation of the millions of different species on the earth and the genetic diversity within these species. Biodiversity is important because humans depend on animals and other species to live and grow and much as animals and other species depend on humans to live and grow. It's important because it is based on the evolution of other species.

What is the connection of the Human Sciences with biological medical and animal sciences?

Human sciences, such as psychology and sociology, draw on principles from biological, medical, and animal sciences to understand human behavior and society. These fields share a common interest in studying the biological basis of behavior, health, and social interactions to gain insights into human nature and society. By integrating knowledge from these disciplines, researchers can develop a more comprehensive understanding of human behavior and societal dynamics.

What is meant by non-redundant protein?

Redundant protein is a term used in bodybuilding where the person takes so much protein, some of it can't be used by the body.

Non-redundant protein refers to the protein which is actually used and absorbed by the body.

This term is also used when referring to enzyme biology for when the substrate is protein.

What is morphology?

Morphology is used in linguistics. It's where how words are made, formed, shaped, and displayed are studied. It studies pictures used as words as well.

study of the mechanical and evolutionary relationships of morphology to behavior.

Is diversity good or bad?

In general, diversity would be desireable in a society or social setting. The group as a whole would benefit from having different skills, talents, opinions and points of view. Of course, the group has to be tolerant and willing to accept diversity; otherwise the diversity would cause conflict.

What is Krebs cycle?

The Krebs cycle is a cycle that is after glycolysis which allows the cell to get more ATP and have more ATP efficiency than that of glycolysis itself or fermentation and glycolysis. Infact, it makes the ATP effeciency about 20 times of glycolysis itself!

Here is the Krebs cycle:

Step 1: The acetyl CoA (a two carbon) joins with oxaloacetic acid (a four carbon). The CoA (Coenzyme A) is returned back to the mitochondira. The result is a six carbon called citric acid.

Step 2: The citric acid gives off carbon dioxide and gives a hydrogen ion (H+) to NAD+ resulting in NADH. Since the citric acid gave off a carbon in the form of CO2, (carbon dioxide) it is now a 5-carbon molecule.

Step 3: The 5-carbon molecule then gives off CO2 once again, gives a hydrogen ion(H+) to NAD+ resulting in NADH, and in this process, phosphate joins with ADP to create ATP. The resulting molecule is a 4-carbon.

Step 4: The 4-carbon molecule gives a hydrogen ion (H+) to FAD (similar to NAD), which results to FADH2.

Step 5: The 4-carbon molecule once again gives off H+ to NAD resulting into NADH. The 4-carbon molecule is then known as oxaloacetic acid, and the cycle begins again.

Remember:glycolysis produces 2 pyruvic acid molecules, which produces 2 acetyl CoA molecules (and 2 NADH), which means that for every molecule of glucose, the Krebs cycle happens twice.

The resulting amounts of NADH and FADH2 go through the electron transport chain and the enzyme ATP synthase to produce a waste of water, ATP molecules, and a restoration of the NADH to NAD+ and the FADH2 to FAD+ so that they can be used again in the Krebs cycle.

How are the concepts of alienation and community related?

The concept of alienation typically involves feelings of disconnection and isolation from others or society. In contrast, community revolves around the idea of belonging and shared connections with others. Addressing alienation often involves fostering a sense of community, as strong social connections can help individuals feel more included and supported.

What is another name for the Krebs cycle?

Tricarboxylic acid cycle, the citric acid cycle, and the Szent-Györgyi-Krebs cycle

How does taxonomy make sense of the world's biodiversity?

Taxonomy organizes and classifies organisms based on their shared characteristics, helping to make sense of the world's biodiversity by providing a systematic way to categorize and understand the relationships between different species. It allows scientists to study and compare organisms, identify new species, and track evolutionary history. By assigning unique names to each species, taxonomy helps researchers communicate accurately about the vast diversity of life on Earth.

What is the Need to study modern virology?

Virology is the scientific discipline concerned with the study of the biology of viruses and viral diseases, including the distribution, biochemistry, physiology, molecular biology, ecology, evolution and clinical aspects of viruses.

'Firstly, the increasing importance of virology is clearly linked to the fact that we know more and more viruses, understand their links to certain diseases better and that epidemiology looks at certain viral infections in new ways: all of a sudden we recognise viruses where we did not see them before.

Can you find five different ways to use decimals?

  1. Representing parts of a whole: for example, 0.5 represents half of a quantity.
  2. Money calculations: decimals are commonly used when dealing with amounts less than a whole unit, such as $4.25.
  3. Measurement: decimals are used in metric units, such as 2.5 centimeters.
  4. Percentage calculations: converting percentages to decimals (e.g., 50% = 0.5) is a common practice in math.
  5. Data analysis: decimals are used in statistical analysis to represent parts of a whole or values between whole numbers.

What biological process includes chemical reactions that break down materials?

The biological process that includes chemical reactions that break down materials is called catabolism. This process involves the breakdown of large molecules into smaller ones, releasing energy stored in those molecules. Catabolism plays a crucial role in providing energy for cellular activities.

What is the biodiversity of a prawn?

Prawns support biodiversity by serving as a food source for many predators and contributing to ecosystem balance and nutrient cycling. They can also increase biodiversity by creating habitat structure within their environment. Additionally, prawns themselves exhibit diversity within their own species in terms of physical characteristics, behavior, and habitat preferences.

What is the importance of the nutrient cycle?

Food nutrient cycle is a process by which nutrients are passed from living things to non-living things in a continuous cycle.

Nutrients are the chemicals needed by all living things and are continually cycled through ecosystems.

Examples: Water, Carbon, Nitrogen and Phosphorous.

Water - to drink

Carbon - plants absorb to created oxygen

Nitrogen - Plants gather it from the atmosphere (we can't use it in this form), the Nitrogen is converted into Nitrates which plants use and then released back into the atmosphere as nitrogen.

Phosphorous - absorbed by plants.
All of the life on earth revolves around a few key nutrients and in combination with energy form the sun it is theses nutrients which are required by all of earth's producers. These nutrients are essentially contained within a closed system on earth, which means no nutrients enter or leave the biosphere in large quantities. For this reason there is a limited amount of the essential nutrients available to the producers, so the available nutrients such as carbon, nitrogen and phosphorus must be recycled and reused by organisms. The recycling of these nutrients involves interactions between both the living organisms and the physical environment, so they are called biogeochemical cycles. These cycles are often considered to be "leaky" since nutrients such as nitrogen and phosphorus may be carried away in rain water to the deep ocean where it is removed from the cycle, other sources of nutrient loss include harvesting and burning of organic material. The following nutrient cycles are of utmost importance to all life and earth and are reported on thoroughly.

Nutrient Cycles:

· Water Cycle

· Carbon Cycle

· Nitrogen Cycle

· Phosphorus Cycle

What are some negative effects of death?

Some negative effects of death include grief and loss for loved ones, emotional and psychological distress for those left behind, and disruption of social connections and relationships. Additionally, death can bring financial burdens and practical challenges for those left to handle the affairs of the deceased.

Give examples of tangible and intangible dead-weight loss to society by govt policies?

  1. Tangible dead-weight loss: Government-imposed tariffs that create inefficiencies in the market, leading to higher prices for imported goods and reduced consumer surplus.

  2. Intangible dead-weight loss: Regulatory barriers that stifle innovation and prevent new businesses from entering the market, resulting in lost opportunities for economic growth and development.

What is piecework?

Piecework is work paid for according to the quantity produced i.e. you might be paid piecework if you are employed by a telemarketer selling carpet cleaning in a home; the employer will only pay you for the number of customer who sign up for the cleaning, rather than for the amount of time you actually spend on the telephone.

Can Durga take human form?

In Hindu mythology, Durga is commonly depicted as a goddess with multiple arms riding a lion. While she is primarily worshipped in this form, some stories mention instances where she takes on a human form to fulfill a specific purpose or interact with specific individuals.

How do you do a SCIENCE folio?

To create a science folio, you can start by selecting a topic or experiment to investigate. Gather relevant information, data, and visual aids to support your findings. Organize your folio with sections such as introduction, methodology, results, discussion, and conclusion to present your work in a clear and structured manner. Make sure to follow any specific guidelines provided by your teacher or institution.

In what matter does individuality and identity become essential in a conformist world?

Individuality and identity become essential in a conformist world as they allow people to express their unique thoughts, beliefs, and values. Through individuality, one can maintain a sense of self and stand out from the crowd, fostering creativity and innovation. Embracing one's identity in a conformist society can also challenge societal norms and encourage others to think differently.

What is the definition of a light cycle?

A light cycle is a repeating pattern of light and dark periods that organisms experience over a 24-hour period, affecting biological processes like sleep-wake cycles and hormone production. It is essential for regulating circadian rhythms in plants, animals, and humans.

How do humans affect biodiversity?

Humans usually affect the population of other animals badly. Most species decline in number, get sick, hunted and eventually die/go extinct (think of apes, deer, wolves). However, there are animals who profit from humans, like pets, farm animals, rats and gulls, but also cockroaches, ants and other insects. Most bacteria also do well under human influence.

Wild animals, who can't be domesticated, are not influenced for the good by humans. Although we 'try' to protect them, humans do on the whole more harm than good.

What is meant by divisible pool?

A divisible pool refers to a shared resource or fund that can be partitioned or divided into smaller portions to be allocated to different individuals or entities. This type of pool allows for flexibility in distribution and can be divided without impacting the overall quantity or value of the resource.

What is meant by 'randomly assorting epistatic genes'?

Randomly assorting epistatic genes refers to the way in which multiple genes interact and segregate independently during gamete formation. Epistatic genes are those that mask the effect of other genes. When these genes are randomly assorting, their impact on the phenotype of an individual is determined by chance rather than a specific pattern of inheritance.
