Beans in the dark will grow faster then the beans in the light why?

Beans grown in the dark tend to grow faster than those grown in the light because they allocate more energy towards elongating their stems to reach for light. In the absence of light, the energy is redirected into stem growth instead of leaf development, resulting in taller plants.

What happens to the rate of photosynthesis when the CO2 levels exceed 3 percent?

When CO2 levels exceed 3 percent, the rate of photosynthesis typically increases initially due to the increased availability of the substrate for photosynthesis. However, beyond a certain point, the rate of photosynthesis can decrease as the high CO2 levels may lead to photorespiration and other metabolic imbalances in the plant cells.

Why humans have one offspring at a time while some animals have a litter?

Because humans reproduce quickly and there a lot of us and we have little threat from predators, while other animals such as fish and insects may only reproduce once or twice in their lifetime so they have a lot of them so the offspring have a better chance of survival and so the population still thrives.

Human offspring also require a lot more energy and resources to raise to maturity. Unlike most mammals, our brains are not even close to being fully developed at birth. Part of the reason for this is that our brains would not be able to fit through the birth canal if they were their fully-developed size. Our survival depends on a lot of learned behavior (versus instinct). One baby is already a lot to handle for a human parent.

What happens to the partial pressure of carbon dioxide during breath holding?

The partial pressure of carbon dioxide increases as a function of time, depending on how long you hold your breathe. Initially, this will cause some discomfort and lead to a mild headache or muscle fatigue if you are not breathing properly during strenuous exercise. However, with proper training (like that undertaken by swimmers), you can hold your breath longer while pushing your body to perform optimally.

On what basis are organisms generally classified?

Organisms are generally classified based on their characteristics and evolutionary relationships. Scientists consider factors such as physical traits, genetic similarities, and shared ancestry to group organisms into larger categories like kingdoms, phyla, and classes. This system helps to organize and understand the diversity of life on Earth.

How do you meet diversity?

You can meet diversity by engaging with a wide range of people from different backgrounds, cultures, and perspectives. This can include attending cultural events, joining community groups, and seeking out opportunities to connect with individuals who have experiences different from your own. Embracing diversity can help you learn, grow, and develop a greater understanding of the world around you.

Another name of water-loving plants?

Plants which live in water (such as waterlilies) can also be called aquatic plants, plants which live in marshy ground or at the edges of ponds (such as reeds) can also be refered to as marginal aquatics. Moisture loving plants is another term which is often used.

Why maintaining a biodiversity is important?

Maintaining biodiversity is important because it helps to support ecosystems by ensuring that different species play their unique roles. Biodiversity also contributes to ecosystem services such as pollination, nutrient cycling, and pest control, which are essential for human well-being. Additionally, biodiversity provides genetic diversity that can increase the resilience of species to environmental changes and threats.

Carbon dioxide acceptor in the calvin-benson cycle is?

The carbon dioxide acceptor in the Calvin-Benson cycle is ribulose-1,5-bisphosphate (RuBP). RuBP is a 5-carbon compound that combines with carbon dioxide in the first step of the cycle to form an unstable 6-carbon compound, which eventually leads to the production of glucose.

What is bassia longifolia plant?

Bassia longifolia, also known as Kallar grass or Thada grass, is a perennial shrub that grows in arid and semi-arid regions. It is drought-resistant and provides fodder for livestock. The plant is used for soil conservation, reforestation, and erosion control.

What is meant by the term human gene pool?

Biodiversity refers to the large number or variety of plants and animals in an ecosystem.

A gene pool is the complete set of unique alleles in a species or population. So, when there is diversity in the gene pool, there is difference in the characteristics of species.

By what do bacteria loco-mote?

Bacteria can move using flagella, which are whip-like appendages that spin and propel the bacteria forward. Some bacteria can also move using pili or by secreting slime to glide along surfaces. Additionally, bacteria can move in response to stimuli such as light, temperature, or chemical signals.

All the organisms classified into the domain?

The domain system classifies organisms into three main domains: Bacteria, Archaea, and Eukarya. Bacteria are single-celled prokaryotic organisms, Archaea are also single-celled prokaryotes but are more closely related to eukaryotes than bacteria, and Eukarya includes all eukaryotic organisms, which are typically multicellular and have a nucleus.

What does Biodeversity mean?

Biodiversity refers to the variety of life forms in a particular habitat or ecosystem. It encompasses the diversity of species, their genetic variation, and the interactions they have with each other and their environment. Maintaining high levels of biodiversity is crucial for ecosystem stability and resilience.

What would happen if the first link was removed from the food chain?

All herbivorous animals (animals that eat only plants) would die, because they would have nothing to eat. Bigger animals that eat the herbivorous animals would die, because there would be no small animals to eat. Humans would not have any meat because all the big and small animals are now dead. We would all have to be vegetarians, and because there are no longer any plants (including vegetables and fruit) we would also starve.

But plants produce oxygen, so we would all choke to death before we could starve.

Why is biodiversity important to ecosystems?

ill give you an example and ill tell you what I mean.

see, say for example your mother likes only men and all the men around her are gay. what is she going to do? ill tell you what she does, she has to start making relations with women around her, girl on girl action in order to fit in the bio diverse system of ecology. she sleeps with women she has helped the ecosystem by creating more gays in the system.

Real definition: biodiversity is important to the ecosystem because it ensures diversity with in species. DIVERSITY BETWEEN SPECIES BEGINS WITH DIVERSITY WITH IN SPECIES.

Why biodiversity should be conserved?

Biodiversity should be conserved because it provides ecosystem stability, resilience to environmental changes, and contributes to important ecosystem services such as pollination, water purification, and climate regulation. It also supports human well-being by providing food, medicine, and recreational opportunities. Additionally, conserving biodiversity helps preserve unique species and genetic diversity for future generations.

What does Hippo stand for in terms of biodiversity?

HIPPO stands for the major threats to biodiversity: habitat destruction (H), invasive species (I), pollution (P), human overpopulation (P), and overharvesting (O). These factors are the primary drivers of species extinction and loss of biodiversity around the world.

Is hydrogen gradient across the mitochondrial inner membrane a cellular energy currency?

ATP molecules are essentially cellular energy currency. The hydrogen gradient (or proton gradient as it is technically called) is responsible for the functioning of a protein complex called ATP synthase which in turn is responsible for the synthesis of ATP molecules. Therefore, the proton gradient is the driving force for the synthesis of ATP molecules.

What is the Average IQ of an American Citizen?

The average IQ for anyone is 100. It forms a bell-shaped curve. Stand deviation is 70-130 I think, but don't quote me on that. IQs are adjusted for age. There is no such thing as a perfect IQ test. But lets pretend there is one. If you took this ideal IQ test at any point in your life, you would get the exact same score every time unless you developed some type of mental illness. There would be no highest or lowest possible score. Of course this impossible with a finite number of questions, because you could get them all right. Actual IQ tests tend to increase slightly with every year spent as a student, and then decrease very gradually after you finish your education. This shows that you are learning something in your education that is giving you an advantage on the IQ test. An ideal IQ test is impossible to prepare or study for and learning new things shouldn't effect it.

Why over fishing bad is for biodiversity?

Overfishing can lead to the depletion of certain fish populations, disrupting the balance of marine ecosystems and reducing biodiversity. This can have cascading effects on other species that rely on those fish for food or habitat. Loss of biodiversity can decrease ecosystem resilience and stability, making it more vulnerable to environmental changes.

What causes overfishing?

Over fishing started about in the 1950's. since then it has largley increaed cause of the growing numbers of illegal fishermen. And now a group calles Dinuka gergouse hadusinghe known as PLumika is stopping this. this is the worst threat our ocean can face.

What is meant by the saying many hands make light work?

This saying means that when many people work together on a task or project, it becomes easier and quicker to accomplish. By dividing the work among multiple people, each person's individual contribution lessens the burden on everyone, making the overall workload feel lighter.

Where does the Calvin Cycle occur in C3 plants?

The Calvin Cycle occurs in the stroma of the chloroplast in C3 plants. This cycle is part of the light-independent reactions of photosynthesis where carbon dioxide is converted into sugar molecules using ATP and NADPH generated during the light-dependent reactions.
