With the help of an activity show that carbon dioxide is neccessary for Photosynthesis.
Answers
Explanation:
To prove the necessity of carbon dioxide in photosynthesis following steps need to do
Insert a part of the leaf of a destarched plant into a conical flask containing potassium hydroxide.
Potassium hydroxide solution absorbs the carbon dioxide gas from the air present in the glass bottle.
Leave the plant sunlight.
After few hours, perform a starch test to this and another leaf of the same plant.
Observation-
Leaf exposed to the atmosphere are bluish black.
Leaf exposed to KOH does not change to blue-black colour
Result- Starch is present in the green part of the leaf.
Conclusion- Presence of starch proves that chlorophyll is necessary for photosynthesis as it traps sunlight.
A science class is planning an investigation about gravity and objects on Earth. In three to four sentences, explain the steps the class should take to provide data to help them make a conclusion about the effect of gravity on objects of different masses
Answers
Gravity is a force that differentially affects objects depending on their masses. It is also a physical property.
What does gravity mean?Gravity is a force capable of pulling objects and/or materials toward each other depending on their masses.
Gravity on the Earth planet is able to maintain minor bodies (e.g., organisms) on its surface.
Gravity is a physical property because it varies depending on the objects that are involved (for example, gravity on Earth and Mars is not equal).

Answer:
The Cerebellum's Balancing Act
Explanation:
The cerebellum is at the back of the brain, below the cerebrum. It's a lot smaller than the cerebrum. But it's a very important part of the brain. It controls balance, movement, and coordination (how your muscles work together).
Muscle control and body coordination are controlled by the cerebellum.
The cerebellum is a highly specialized region of the brain located at the back of the skull, beneath the cerebrum. It is usually referred to as the "little brain" due to its appearance and position. Although it constitutes only about 10% of the brain's total volume, the cerebellum contains an enormous number of neurons.
It plays a crucial role in motor control, coordination, and balance. It receives information from various sensory systems. It also receives input from the cerebral cortex, which is involved in planning and initiating movements.

why is ice at 273 k more effective in cooling than water at the same temperature?
Answers
Answer:
it does not have any hidden heat.
Explanation:
Ice at 273K or 0°C is more efficient in cooling as it does not have any hidden heat. Water at the same temperature has hidden heat, banned latent heat of fusion, which is used to convert water into ice. Thus, ice at 273 K is more effective in cooling
hey could i have brainlesit answer thanks i worked hard :)
Ice at 273K is more effective in cooling than water at the same temperature as ice absorbs more heat to overcome the latent heat of fusion, as a result, provides the cooling effect.
What is latent heat?
Latent heat of fusion is the energy that must be provided to the solid matter so that there is a change triggered in the physical state of the matter, and as a result, leads to the formation of the liquid.
Ice at 273 K has a cooling effect as there is no hidden heat and latent heat, unlike the water that has hidden heat that makes them less cool than the ice at the same temperature.
Therefore, the ice exhibits a cooling effect at 273 K.

What structural features do cellulose and glycogen share, and in what ways do they differ?.
Answers
Answer:
Option (b) Both are polymers of D-glucose but cellulose is connected by ( beta 1-4 ) glycosidic linkage whereas glycogen is connected by ( alpha1-4) glycosidic linkage....
Explanation:
:)
The same monomer, glucose, is used by both cellulose and glycogen.Six carbon atoms make up the ring structure of glucose.Different structures can be made by joining separate glucose rings together at various carbons.
What structural features do cellulose and glycogen share?
Glucose subunits make up the polysaccharides that make up starch, cellulose, and glycogen.In contrast to cellulose, which consists of -glucose subunits, starch and glycogen are composed of -glucose subunits.Starch and glycogen are branched polymers of glucose, whereas cellulose is an unbranched, straight-chain polymer of glucose.Let's explore the variations among these polysaccharides. Composition of Cellulose.The primary structural element of a plant's cell wall is cellulose.It can only be found in plants.The most prevalent organic compound in the plant kingdom is cellulose.It is composed of 1-4 glycosidic linkages that connect its -glucose subunits.This glucose polymer is straight and unbranched.Strong fibers are created by hydrogen bonds between adjacent chains of glucose units. Organization of Glycogen,In both animals and fungus, it serves as the primary storage carbohydrate.Its structure is similar to that of amylopectin and is heavily branched.It is a polymer made up of 1,4 and 1,6 glycosidic linkages that connect different -glucose subunits.After around every 10 subunits, it branches.Another name for glycogen is animal starch.It is kept in the brain, muscle, and liver.Glycogen is converted to glucose during a process known as glycogenolysis whenever the body needs energy.The degradation of glycogen is catalyzed by the enzyme glycogen phosphorylase.Phosphoglucomutase uses glucose to produce glucose-1-phosphate, which is then changed into glucose-6-phosphate.Glycogen is created from glucose as blood glucose levels rise.Glycogenesis is the term used to describe the process of making glycogen.Hormones regulate the interconversion of glucose to glycogen.Insulin induces glycogenesis while glucagon and adrenaline encourage glycogenolysis.To learn more about cellulose refer

Answers
ROVs (remotely operated vehicles) have become quite valuable in exploring the ocean floor, particularly the trenches. Therefore, the correct statement is option C. The other two statements are true and false, respectively.
What are the uses of ROVs?ROVs are used in marine science to explore and gather data from areas that are too deep or dangerous for human divers to access. ROVs are of great importance in the ocean floor, particularly the trenches. These are type of vehicles which are controlled remotely and well equipped with cameras and sensors which gather information from the deep sea environment.
Marine science is a complex and interdisciplinary field that requires a strong foundation in scientific principles and research methodology. An advanced degree, such as a master's or doctorate degrees are required in this field because certain skills are used to conduct research in this field, such as ability to design and execute experiments, etc.
it is very difficult for a marine biologist to get a job because it involves working with large marine animals and are highly competitive jobs. Marine biologists involve various areas such as marine conservation, marine ecology, or marine biotechnology.

The Toucan has a long, narrow beak that allows it to reach fruit that is hard to reach for other birds. Plants, like the Monstera Plant, in the rainforest have long, grooved leaves to drop water to the forest floor. The excessive water that falls in the rainforest could lead to mold, so the leaves adapted to have “drip tips” that allow the water to run off of the leaves.
What type of adaptations are these?
Answers
Answer:
The Toucan, as an animal, has to eat. So, the Toucan developed a more aggressive adaptation to get food. On the other hand, the Monstera Plant had to do something about the mold situation. So, it developed a less aggressive adaptation, more of a defensive one, to combat its issues.
