Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

Your favorite plant has begun to wilt. You feel the soil in the pot and find that it is very dry. You water your plant and about 20 minutes later you discover the plant is standing up straight again. Is this an example of osmosis or diffusion? Please explain:
Answers
Answer:
Explanation:In this article we will discuss about the water relation in plants.
Plant physiology is the study of vital or functional activities of plants. And water is essential for these functional activities.
What for water is needed:
i. Water is absolutely essential for protoplasm because its hydration is essential for its proper organisation and proper functioning of its organelles.
ii. Water is the carrier of various dissolved substances like gases, minerals, organic and inorganic substances etc.
iii. Water is necessary for metabolic reactions of the cell e.g., photolysis of water.
iv. The rigidity and turgidity of cells is maintained by and large by water.
v. Water forms a continuous network throughout the plant through which dissolved substances move up.
vi. Water makes up the loss of water during transpiration and guttation.
Thus almost all the functional activities of plants depend on the water relation.
Under water relation we study the following points:
a) How does water enter into the plant – This functional activity is studied under the heading ‘Osmosis’.
b) How does water move up inside the plant – It is studied under ‘Ascent of sap’ or ‘Translocation of sap’.
c) How is water lost from the plant – It is studied under ‘Loss of water’ or ‘Transpiration’.
Diffusion:
The movement of the molecules of gases, liquids or solutes from the regions of higher concentration to the regions of lower conc., until the molecules are evenly distributed throughout the available space is known as Diffusion.
Diffusion Pressure Deficit/Water Potential (DPD/WP):
Diffusion pressure deficit (DPD) is also called suction Pressure (S.P). It is the ability of a cell to draw water. It is the force per unit area (i.e., pressure) by which water enters into a cell. A pure solvent is supposed to have maximum diffusion pressure.
When certain solute particles are added to the pure solvent, the diffusion pressure of the resulting solution is lowered. The amount by which the diffusion pressure of a solution is lowered than that of its solvent at the same temperature and atmospheric pressure, is called DPD. The term DPD was introduced by Meyer in 1938.
But according to the recent trend, diffusion of water is explained in terms of Water Potential. DPD is the positive value whereas water potential is the negative value.
Turgor Pressure (T.P.):
T.P is the outward pressure exerted by the cell solution on the cell wall which is developed due to osmotic diffusion of water. In equilibrium inward pressure is also given by the cell wall on the cell solution in an equal amount, which is called wall pressure or Hydrostatic Pressure.
Turgor Pressure is also called Pressure Potential (PP) which has positive value.
Chemical Potential:
The free energy per mole of a chemical substance is called its chemical potential. Chemical potential of water in a solution is reduced by the addition of solutes.
Osmosis:
i. Osmosis is essentially a special type of diffusion of liquids.
ii. The term ‘Osmosis’ was given by Abbe Nollel.
iii. Osmosis Means:
a) Movement of solvent.
b) From a region of lower concentration of solution.
c) To a region of higher conc. of solution.
d) Through semi-permeable membrane (SPM).
iv. Plasma or cell membrane is a semi-permeable membrane. At higher temperature plasma membrane becomes permeable.
Illustration:
Answer:
Example of osmosis.
Explanation:
Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
Diffusion is the net passive movement of molecules or particles from regions of higher to regions of lower concentration.
The answer cannot be diffusion, and thus, is osmosis.

• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

DUE IN A FEW MINUTES: A cell membrane is more flexible than a brick wall. Why might many cells benefit from a flexible cell membrane?
Answers
Answer:
A flexible cell membrane benefits cells because it allows them to survive in a range of environments, and the cell membrane must be reasonably flexible to allow certain cells, such as red blood cells and white blood cells, to work properly.
Explanation:
hope this helps :D
Many cells benefits from a flexible cell membrane because of its ability to allow materials in and out of the cell.
The cell is the structural and functional basic unit of a living organism which is surrounded by a membrane called the cell membrane.
The cell membrane can be said to be more flexible than a brick wall because it is made up of phospholipid bilayer that controls materials in and out of the cell but a brick wall does not allow the passage of any material.
The cell benefits from the flexibility of its cell wall as the passage of materials in and out of the cell helps to maintain a constant environment inside the cell.
