What is divergent evolution in whch ancestral species evolve into an array of species to fit a number of diverse habitats?

Divergent evolution is when a common ancestor gives rise to different species adapted to different environments or ecological niches. This process results in the evolution of distinct traits in each species to better suit their specific habitats and lifestyles.

Mention a reason for the importance of biodiversity on human life?

Biodiversity is the very existence needs of every humans and animals or say every living organisms.It supports, maintain and functions human lives..... Hence biodiversity is important for human lives. It is the duty of us that we sustain our biodiversity for the upliftment of our future..

Define biodiversity Explain the importance of biodiversity?

Biodiversity refers to the variety of living organisms within an ecosystem, including species diversity, genetic diversity, and ecosystem diversity. Biodiversity is crucial for the stability and resilience of ecosystems, as it supports ecosystem functions such as nutrient cycling, water purification, and pollination. It also provides essential resources for human well-being, such as food, medicines, and raw materials. Additionally, biodiversity contributes to cultural, aesthetic, and recreational values, enriching our quality of life.

How would the removal of a keystone species affect an ecosystem's biodiversity?

The removal of a keystone species could lead to a decrease in biodiversity within an ecosystem. Keystone species play crucial roles in maintaining the balance and diversity of an ecosystem by influencing the abundance of other species. Removing a keystone species can cause a ripple effect, disrupting the ecosystem's structure and potentially leading to the decline or even extinction of other species.

What does NADPH add to the Calvin-Benson cycle?

NADPH serves as a reducing agent in the Calvin-Benson cycle, providing electrons to drive the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate. This reduction step ultimately leads to the production of glucose during photosynthesis.

What are the adaptations of a brittle brush plant?

Brittlebush plants have adapted to survive in arid environments by having deep taproots to access water, silvery leaves to reflect sunlight and reduce water loss, and a resinous coating on their leaves to prevent desiccation. They also produce compounds that deter herbivores and have a unique seed dispersal mechanism using wind.

How did Wilson stop the argument among the men?

he reminded them that there would be a battle soon and it was useless to fight amoungst themselves

The value of diversity in teams?

Diversity in teams brings a wider range of perspectives, ideas, and skills, leading to more innovative solutions and better decision-making. It promotes a culture of inclusion and belonging, which enhances creativity and performance. Additionally, it reflects the diversity of the broader society, making teams more relatable and responsive to a variety of stakeholders.

Why is sunlight a limiting factor for the aquatic ecosystem?

Sunlight is a limiting factor for the aquatic ecosystem because it is essential for photosynthesis to occur in aquatic plants and algae, which form the base of the food chain. Decreased sunlight penetration due to water depth, turbidity, or shading from vegetation can limit the growth of aquatic plants and algae, ultimately impacting the entire ecosystem.

The Calvin cycle performs the light dependent reactions?

This is incorrect. The Calvin cycle is actually a series of light-independent reactions that take place in the stroma of the chloroplasts. It uses the products of the light-dependent reactions to convert carbon dioxide into glucose.

What is morphological arrangement?

Morphological arrangement refers to the way words are structured and organized in a language, particularly in regards to how prefixes, roots, and suffixes are combined to create complex words. It involves understanding how morphemes, the smallest units of meaning in language, are interconnected to form different word forms and variations. Study of morphological arrangement helps in analyzing word formation processes and understanding the relationship between form and meaning in language.

Why are sea lions important?

In a nutshell, the sea is important for human development. It is a place where trade takes place and is the home for hundreds of different species of wildlife. The oceans also play a major role in the planet's climate.

Why is a decrease in biodiversity bad?

Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).

Why are wildlife corridors important?

Without wildlife corridors, biodiversity would increase greatly as these corridors provide shelter and a method of moving from one location to another, for small, often vulnerable animals. Therefore, if they were removed, only those animals which could survive in the open and escape predation easily would remain.

Why does biodiversity enable organisms to have a better chance of survival?

Biodiversity increases the likelihood of finding alternative resources and habitats to survive in changing conditions. It also promotes genetic variation, reducing the risk of inbreeding and increasing the potential for adaptation to new challenges. Additionally, diverse ecosystems are more resilient to disturbances and can recover more effectively from environmental changes.

Distinguish between hypotheses that explain biodiversity and those that explain the origin of life?

Hypotheses that explain biodiversity focus on the variety of species and ecosystems that exist today, often exploring factors like evolutionary processes and environmental influences. Hypotheses that explain the origin of life are concerned with how life first emerged on Earth, including theories like abiogenesis and panspermia. Essentially, biodiversity hypotheses address the diversity of life forms, while origin of life hypotheses address the initial emergence of life itself.

Describle three major causes of biodiversity loss in marine ecosystems?

well, pollution is a main one... especially factories that lie on coastal areas...

over fishing is another major reason

also climate change causes the destruction of the coral and reef habitats which conatins all the nutrients marine life need

Why do you think that it is important to maintain biodiversity on our planet?

There are many good reasons as to why biodiversity should be preserved. One strong reason as to why I believe biodiversity should be protected has been the immense amount of beneficial substances and products that we can gain, and have gained, from the many species of organism found in nature. We rely on biodiversity for the production of medicines. Farmers rely on biodiversity when a disease devastates one type of crop. For instance, remember the Ireland potato famine, where only a few types of potato were grown and relied upon. Approximately one million died and a million more emigrated from the country when the potato became diseased. If more potato species had been around, there could have been one, a few, or even plenty more that had the ability to resist the disease, thus, preventing starvation.

Many people assume that biological diversity doesn't concern them. However, these individuals do not realize how interdependent all species are upon one another. Maintaining the biodiversity of the planet will ensure a higher quality of life for all species of the planet, including humans. Since the human species has proliferated the planet, and we now occupy many different kinds of ecysostems/biomes, our health as a species is dependent on the health of the biosphere (all of the areas on Earth that support life). After all, we are not exempt from the health of the planet, as we are all animal residents of this spaceship as well, only with an immensely increased ability to affect it due to industrial/technological advancement. We should simply ask: do we want our home to be a desolate wasteland, or a lush garden with an immense variety of fruits and other organisms?

What are Problems in the biological species concept?

There are two main problems that can be identified in the biological species concept. This concept emphiasizes interfertility between organisms. However, reproductive barriers between sexual reproducing species are not always effective. Sometimes, individuals of different species interbreed and produce offspring call hybrids. Also this concept fails to describe species that are predominantly asexual in their reproduction, including all bacteria as well as some protists, fungi, plants, and even a few animals.

Is digesting a banana a reversible change?

No, digesting a banana is not a reversible change. Once the banana is broken down and its nutrients are absorbed by the body, it cannot be easily reconstituted back into its original form.

How were the Norfolk broads formed?

The Norfolk Broads were formed around 7,000 years ago by the flooding of medieval peat excavations. These excavations created a network of shallow lakes and waterways that are now a popular destination for boating and wildlife enthusiasts in Norfolk, England.

Who is affected by biodiversity?

All living organisms on Earth are affected by biodiversity, as it refers to the variety and variability of life forms and ecosystems. Changes in biodiversity can impact ecosystems, species survival, and overall ecosystem health, which in turn can affect human well-being through services such as food, clean water, and climate regulation.

What characterizes a species?

A species is a set of groups of naturally occurring populations that do or hypothetically could successfully breed with each other, and that are isolated from other such groups. This means that if two animals belong to the same species, they could reproduce and produce fertile offspring. Also, the second part of the definition means that if an animal had two natural populations, one in South America and one in Siberia, they would have to divide it into two species, even if they seemed identical. This definition of species isn't totally accurate, especially since it assumes that the species reproduces sexually, which isn't always the case.

How does over hunting by humans affect biodiversity?

Many groups, such as PETA and the EPA are completely against hunting. Hunting actually helps to keep the natural balance healthy. However, overhunting can have a terrible effect on the ecosystem. It can lead to the extinction of a species. Think about it like this, owls, cats, and foxes eat mice, voles, and frogs. Mice voles and frogs eat grass, wheat and insects. If suddenly, all insects died, frogs couldn't eat them, and would starve and go extinct. If forgs died, there's more food for mice and voles, and their population would go up. Eventually, the higher population wouldn't be supported because there isn't enough food, then mice and voles would die off. Then, owls, cats and foxes would starve to death because the frogs, mice and voles are dead. Eventually, it could work its way up to humans. When populations are too high, hunting is good.
