explain the global water crisis in your own words
Explanation:
Water is the basic necessity of every human being. But, water scarcity is a major issue that is rising very rapidly in modern-day India. The problem has become so severe that in many states the groundwater has almost dried up and people have to depend on water supply from other sources. In addition, water is one of the most misused commodities that we still waste. It is the central point of our lives but not the central point of our focus.
In the past, people understand the value of water and plan their lives around it. Moreover, many civilizations bloom and lost on account of water. But, today we have knowledge but we still fail to understand the value of water.
Reason for Water Scarcity in India
Water scarcity is the cause of mismanagement and excess population growth of the water resources. Also, it is a man-made issue that continues to rise. Besides, some of the reasons for water scarcity are:
Wasteful use of water for Agriculture- India is one of the major food growers in the world. That produces tons of quantity of food to feed its population and export the surplus that is left.
In addition, producing this much food requires a lot of water too. The traditional method of irrigation wastes a lot of water due to evaporation, water conveyance, drainage, percolation, and the overuse of groundwater. Besides, most of the areas in India use traditional irrigation techniques that stress the availability of water.
But, the solution to this problem lies in the extensive irrigation techniques such as micro-irrigation in which we provide water to plants and crops using a sprinkler or drip irrigation.
Reduction in water recharge systems- Due to rapid construction that uses concrete and marbles do not let the rainwater to get absorbed in the soil. But, if we install some mechanism in our houses that can hold the rainwater then we can recharge the groundwater.
Lack of water management and distribution- There is a need for an efficient system that can manage and distribute the water in urban areas. Also, the government needs to enhance its technology and investment in water treatment. Besides, we should ensure optimization at the planning level.
Solutions to Overcome this Problem
Water-free urinal- Urinal waste around 6 liters of water per flush that add up to 25 thousand liters per year. If a male member of the house stops using the flush then they can save lots of water.
Close the running tap- During dishwashing and hand washing people often let the tap running. These running taps waste thousands of liters of water per year. Besides, closing the tap will reduce this problem.
Replace dripping taps- In India it is commonly seen that most of the houses have one or two taps that drop water even when they are close. This running tap wastes up to 30,000 liters of water that nobody bothers to change. So, we should replace these taps immediately.
To conclude, water scarcity has become a more dangerous problem day by day. Also, due to our leniency that we haven’t taken the problem water scarcity seriously. But, now the authorities and people are working to resolve this problem so that our future generations do not have to buy this necessity.
What are some of the ways that pollen can travel from one flower to another?
Answer:
pollinators + the wind
Explanation:
pollinators is probably the best answer here... pollinators are bugs like bees and butterflies that spread the pollen from one plant to another.
Answer:
Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.

Which animal body systems may be involved in homeostasis?
A. only the circulatory system
O
B. only the circulatory system and respiratory system
C. only the nervous system and endocrine system
D. all body systems
The animal body systems which may be involved in homeostasis are only the nervous system and endocrine system.
What do you mean by Homeostasis?Homeostasis may be defined as a circumstance of balance among all the body systems required for the body to endure and function correctly.
The endocrine system consists of a series of glands that secrete chemical regulators known as hormones that play a critical role in maintaining the normal body conditions physically.
The ultimate control of homeostasis is performed by the nervous system which conducts the electric impulse and sends internal and external stimuli signals to the brain.
Therefore, the animal body systems which may be involved in homeostasis are only the nervous system and endocrine system.

C. Cell Membrane
D.Chloroplasts
Answer:
a
Explanation:
Ribosomes would be distributed throughout a prokaryotic cell, but would be found restricted to the nucleus of an eukaryotic cell.
What are ribosomes?Eukaryotic cells have a distinct nucleus that separates the genetic material from the cytoplasm, which is where ribosomes are located in prokaryotic cells. The DNA in eukaryotic cells is packaged into chromosomes within the nucleus, while prokaryotic cells have a single circular chromosome located in the cytoplasm.
The cell membrane is present in both prokaryotic and eukaryotic cells, but chloroplasts are only present in eukaryotic cells that have the ability to perform photosynthesis, such as plant cells.

Each year jonahs dad puts out mum plants on each side of his front steps. An early frost hit prior to the plants entering a state of dormancy, and the mum plants died. What might explain why the plant died?
Answer: The plant died due to frost damage and desiccation
Explanation:
Plants may remain alive in an unfavorable condition for long periods without growing any further, but still have the power to grow under favourable conditions. Such plants are said to be in a state of DORMANCY. This is a gradual process that is made up of series of physical and physiological changes in the plant.
During unfavorable condition, such as in winter periods, scales form over buds to protect them from desiccating or drying out, and from the freezing temperatures. The occurance of these changes in plants are time bound. Therefore if there is change in the weather forecast leading to an EARLIER frost hit prior to the plant entering a state of dormancy, frost damage and desiccation may cause the death of the plant. Frost damage and desiccation occurs when there is lost of moisture from plants without it being able to replenish its water supply through its roots due to the dry air and winds.
As the plant wasn't able to enter the state of dormancy, it lost the opportunity to photosynthesize, grow and store more energy before settling in for the unfavorable season.

Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.
Research this issue, and summarize what’s known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
Answer: Yes.
Explanation: Because if it causes disease or problem then why continue to do it?
Answer: Well, from what my research is saying. cell phones emit low levels of non-ionizing radiation when in use. It can also referred to as radio frequency (RF) energy. And as stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. So, it has not been proven weather or not you could get a tumor or cancer from the energy waves.
Some information about a radio wave is that we can have an energy of around 4 x 10-10 eV.
Okay so, I do think people should limit their cell phone use for other reasons. For one, Phones can be overly addicting, I do speak from experience. Phones can also take up way to much of your time is you're just scrolling around on them.
