Answer:
Urban sprawl can also be called Urbanization and it means the movement of a population from the densely populated cities to the low populated areas around the cities which isn't usually well developed.
Urbanisation has a great impact on the environment because it leads to cutting down of trees which is also known as deforestation.
Deforestation is very harmful for the environment because it creates a form
of dis balance in the environment. Trees are very important to us humans because they provide us with raw materials and oxygen. This means we should always be mindful of deforestation processes.

Science Riddle of the Day: Whats The Most tiniest Virus Ever?
Answer:
The smallest viruses are thought to be the Porcine Circovirus.
Explanation:
A scientist set up an experimental ecosystem in a sealed room with no windows. The experimental ecosystem has plants, and animals that eat those plants. The scientist can control whether the room is light or dark with a light switch outside the room.
The amount of carbon in the air of the ecosystem started out low. Then the amount of carbon in the air started to increase. Is the increase because the scientist switched the light on or because she switched the light off? What happened to the number of energy storage molecules in the living things?
The scientist . . .
a
switched the light off, and the number of energy storage molecules in the living things decreased.
b
switched the light off, and the number of energy storage molecules in the living things increased.
c
switched the light on, and the number of energy storage molecules in the living things increased.
d
switched the light on, and the number of energy storage molecules in the living things decreased.
Answer:
Option-A
Explanation:
In the given question, the artificial ecosystem was prepared by the scientist which included the animals and plants. The light and dark conditions were controlled by a switch and bulb.
In the beginning, the amount of Carbon in the form of carbon dioxide was low due to the utilization of carbon dioxide by plants to perform photosynthesis. Then the amount of carbon dioxide increased in the atmosphere, the reason could be due to less consumption of carbon dioxide. The carbon dioxide is not uptake by plants during night conditions when photosynthesis process slowed down or stops.
Therefore, the dark condition was created by the scientist by switching off the lights and the number of energy molecule decreased as no photosynthesis was occurring.
Thus, Option-A is the correct answer.

Why is the phloem in a leaf important to the roots of a plant?
A. It transports oxygen to the roots of the plant.
O B. It transports blastocysts to the roots of the plant.
O C. It transports water from the roots to the leaves.
OD. It transports carbohydrates to the roots.
Answer:
D. It transports carbohydrates to the roots.
Explanation:
Phloem is mainly used to transport nutrients from their region of production to the region that needs or stores the nutrient.
In photosynthesis, the method that plants make food, starch is produced. As the root hair cells needed energy to function, nutrients is needed so that it can respire and produce energy.
Therefore, when starch is produced, they will travel down the plants by the phloem to the roots where the nutrients is used.
brainlest please
As it delivers carbohydrates to the roots, the phloem in a leaf is vital to a plant's roots. So, the correct option is D.
What is Phloem?The plant tissue known as phloem is in charge of moving sugars, nutrients, and other organic substances from the leaves, where they are made by photosynthesis, to the other sections of the plant, such as the roots, flowers, and fruits.
Phloem has a bidirectional transport system that enables it to carry materials both across and down the plant. Sieve-tube elements and companion cells, which make up phloem tissue, are specialised cells.
A vascular tissue called phloem is in charge of moving sugars (carbohydrates) from the leaves to the roots and other sections of the plant. The plant may transfer the byproducts of photosynthesis through its whole system thanks to a process called as translocation.
Therefore, the correct option is D.

What is an organism that lives on or in another organism and derives its nutrition from that organism?
Answer:
A parasite
Explanation:
Parasitism is a form of symbiosis where one organism lives on/in another organism, as in the question, and gets a benefit from that organism, while the other organism is harmed. This is denoted by +/-, which means that one is positively impacted and one is negatively impacted, as opposed to commensalism, which is +/0, or mutualism, which is +/+.
An example is tapeworms, which are flatworm parasites that live in the human intestine; they benefit while the host suffers.

why does our planet appear blue?
Answer:
Mars is the red planet; the Moon is an ashy grey; Saturn shines yellow and the Sun is a brilliant, blinding white. But our planet, when seen from the depths of space, whether we rise up above our world only slightly, in low-Earth orbit, or whether we travel to the outer reaches of our Solar System, shines a glorious blue.
Explanation:
Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.
Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by more than a third since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change.
Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.
Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
Chlorofluorocarbons (CFCs). Synthetic compounds entirely of industrial origin used in a number of applications,
You might have heard that the ocean is blue because the sky is blue, and water reflects the skies. Well, the sky is blue; that’s for certain.

For both conditions, explain how protein synthesis contributes to the symptoms of the disease
Answer:
Explanation:
Among the causes of protein synthesis disorders, an important place is occupied by various types of alimentary insufficiency (complete or incomplete starvation, lack of essential amino acids in food, violation of a certain quantitative ratio between essential amino acids entering the body).
The protein synthesis correspondingly contributes to the symptoms of the disease by the fact that it produces some dysfunctional or bizarre proteins which significantly stimulate the specific types of disorder in organisms.
What is Protein synthesis?Protein synthesis may be defined as a biological process through which cells make protein in order to perform specific functions within the body of living organisms. It occurs in two stages, i.e. transcription and translation.
Transcription is the stage of protein synthesis through which the effective transfer of genetic instructions in DNA to mRNA in the nucleus takes place. While the process of translation involves the process by which a cell makes proteins using the genetic information carried in messenger RNA (mRNA). It occurs in the cytoplasm of the cell.
The disorder of protein synthesis is occupied by numerous kinds of alimentary insufficiency such as entire or incomplete starvation, insufficiency of mandatory amino acids in food, and violation of essential amino acids entering the body.
