What is homeostatis and how it is occured in plants
Answer:
the property of living organisms in which they keep their internal systems in balance is called homeostatis. In desert regions, plants have reflective surfaces making them cool, they have several adaptation skills like cactus, where its leaves are spines to reduce transpiration. This happens due to the property homeostatis.
Answer:
Homeostasis is the property of living organisms in which internal systems are kept in balance.
Explanation:
Plants stay cool in the desert heat through their reflective surfaces, reduced leaves, or leaves that are parallel to the sun. Desert plants may also have adaptations that help them store water or very deep roots.

why is an athlete given glucose rather than a piece of bread
Answer:
to be healthy and gain more muscle
Explanation:
Glucose is a monosaccharide which means that it can be absorbed without any chemical processes and before a competition it can be metabolized faster. Bread contains starch which is a polysaccharide. That means it has to undergo chemical processing in order to be absorbed.
Glucose⇒intestinal absorption
starch+amylase⇒maltose+maltase⇒glucose⇒intestinal absorption
So, to summarize glucose takes it's effect faster.

Answer:
Explanation:
They discovered that the difference between lactose tolerant/persistence and intolerant individuals was due to a mutation located in another neighbouring gene that controls its persistence.
This gene is the MCM6 gene. This gene affects lactase promoter activity likely causing lactase persistence. It is located in a regulatory region upstream of the lactase (LCT) gene.

Explanation:
Which of Charles Darwin’s main points is depicted in the image? Organisms within a population compete with each other to survive. Over time, beneficial variations will be passed on to future generations. More offspring are produced than can be supported by an environment. All organisms within a population have an equal chance for survival.
Answer:
A). Organisms within a population compete with each other to survive.
Explanation:
Charles Darwin in his evolution theory proposed that the organisms of all species emerge and develop via the 'natural selection' of tiny, inherited discrepancies and these disparities enhance the individual's ability to contest and compete with each other in order to survive and reproduce to continue their existence. This led to the emergence of the phrase 'survival of the fittest' which suggests that in this competition of 'natural selection', only the fittest will survive. Thus, option A is the correct answer.

Which would be an adaptation in a rainforest, but NOT in a desert? A: Skin that blends in with green plants B: Better eyes for hunting prey C: Ability to store water for a long time (Obviously not the answer) D: Very small leaves to trap water
Answer: A: Skin that blends in with green plants
Skin that blends in with green plants is an adaptation in a rainforest, nut not in a desert. Thus, the correct option is A.
What are rainforest adaptations?Some of the most common animal adaptations in the rainforest include camouflage. This adaptation is much like soldiers in the army wear camouflage to blend in with their outside environment, animals use camouflage to move around the rainforest undetected.
Rainforest plants show adaptations which help them to survive better including the shallow root systems which enable them to obtain more moisture and tap into the rich supply of nutrients which are available from rotting plants and animal materials in the upper soil layer of the forests. The leaves of the rainforest trees have special adaptations and are noticeably different from that of eucalyptus leaves.
Therefore, the correct option is A.

which structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out a b c d
Answer:
Stomata
Explanation:
Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.
Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.
STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.

Answer:

A substance that has an influence on the reaction but it does not take part in the reaction is known as a catalyst.
What are the properties of a catalyst?A catalyst has an important property of selectivity which means it only catalyzes a specific reaction. Every reaction is catalyzed by a unique catalyst that is specific to that particular reaction. A catalyst usually undergoes a physical change but does not undergo a chemical change during the reaction.
A catalyst works by increasing the rate of reaction. In a chemical reaction, there is breaking and rebuilding of bonds between different atoms and molecules. This process is made easy with the help of a catalyst which lowers the activation energy and catalyzes the reaction in a smooth manner.

Describe the movement of water molecules in this diagram and identify the state of the solution. Explain why the water molecules moved in this direction
Answer:
A. Water molecules moved from compartment 2 to compartment 1.
B. The water molecules moved in this direction because the concentration of solutes in compartment 1 is greater than that in compartment 2
Explanation:
The setup in the diagram demonstrates the process of osmosis. In the setup, two solutions of different concentrations as shown by the difference in the number of solutes present in each, is separated by a semipermeable membrane. After sometime, it will be observed that the level of the solution in compartment 1 rises while that in compartment 2 reduces. This is because of the movement of water molecules across the membrane from 1 to 2. This process is known as osmosis.
Osmosis is the movement of water molecules across a semipermeable membrane from a region of lower solute concentration or higher concentration of water molecules to a region of higher solute concentration or lower concentration of water molecules until an equilibrium concentration is attained.
This movement of water molecules is due to the difference in concentrations of the two solutions as well as a presence of a semipermeable membrane which allows only water molecules to move across it but not solute molecules.
During ecological succession, why is one type of tree that is short get replaced by taller
tree types?
Answer:
change in environment
Explanation:
During ecological succession, short type of tree get replaced by taller tree because the environment is in favor of the taller trees. The suddenly and drastically change that occurs in an ecosystem is the main reason for ecological succession. In this ecological succession, the old species becomes vanished and replace by new species which has the ability to survive in that changed environment. The short type of tree get replaced by taller tree because the shorter trees did not get sunlight and nutrients from the soil so tall trees takes their place. The tall trees are more competitive that short trees.
