Answer:
Distance is 500 m and displacement is 0.
Explanation:
Distance traveled by an object is equal to the total path covered during the entire journey. Displacement of an object is the shortest path covered.
In this case, we need to find the distance and the displacement of the race car drivers in the Indy 500 m race in a circular path.
In a race, the object must reach the initial position after some time. It means that the final and the initial position is the same. As a result, the shortest path covered i.e. displacement of the car is equal to 0. On the other hand, total traveled distance is 500 m.

Do trees keep their internal parts separate from the outside environment?
Answer:
yes, they do.
Explanation:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)
a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.
b) The two sides of a cell membrane face different environments and carry out different functions.
c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.
d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.
Answer:
The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.
Explanation:
PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .
PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.
On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.
LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.
The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.
Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.
CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?
Answer:
Find the explanation below.
Explanation:
When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.
Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.
Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.
Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

Every single cell organism is able to survive because it carries out
Every single cell of an organism is able to survive independently because it carries out metabolic processes at its own.
What is Metabolism?Metabolism can be defined as the chemical changes or reactions which take place in a cell or an organism. These changes make energy and the compounds which cells and organisms need to grow, reproduce, and stay healthy.
Metabolism is divided into two classes: anabolism and catabolism. Anabolism involves the synthesis of a complex compound from simpler or smaller molecules or atoms. Catabolism involves the breakdown of a complex molecule into smaller and simpler ones.
Living organisms are able to perform the metabolic processes such as respiration, excretion, reproduction, and digestion which is a distinguishing factor from that of non-living organisms.

A famous celebrity has an extreme security system for their estate. The security system includes sensors in the ground as well as on the sides of the buildings. A loud truck drives down the road entering the estate. There is a sensor in the ground and another on the side of the security guard’s shed. If both sensors are 100m from the truck, which sensor will pick up the noise of the truck first and why?
A.
Guard Shed - The sensor on the security guard’s shed will detect the sound first because the sound is traveling through the air and sound will travel fastest through a gas.
B.
Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
C.
Same time - Because the sound is traveling through both the ground and the air at the same time, it will reach both the shed and the ground sensor at the same time.
D.
Neither sensor - 100m is too far for the sound to travel. Neither sensor will pick up the sound of the truck until it is closer to them.
Answer:
B. Ground - The sensor in the ground will detect the sound first because the sound is traveling through the dirt and sound will travel fastest through a solid.
Explanation:
Sound wave is an example of mechanical wave, which means sound waves require a medium to travel through. However, how fast a sound travels is dependent on the kind of medium it travels through. Sound travels fastest via a SOLID medium, then liquid and slowest through gases.
According to this question, sensor in the ground and side of the security guard’s shed were placed in an estate owned by a famous celebrity. A loud truck, then, drives down the road entering the estate.
Based on the principles of sound eaves movement, the sound from the truck will be picked by the sensors in the GROUND first because the sound is traveling through the dirt and sound will travel fastest through a solid.
The small intestine exchanges nutrients to help maintain homeostasis. Through the process of digestion, food is broken down into smaller pieces. Sugar is a molecule that supplies our cells with energy. Sugar is a large molecule and is transported through carrier proteins. Sugar molecules are often transported into the bloodstream even when the concentration of glucose is higher in the bloodstream than in the intestine. Based on this scenario, is the transport of glucose accomplished through osmosis, diffusion, or active transport?
Answer:
Diffusion
Explanation:
The sugar is spreading to various places within the body and is trying to make one place less concentrated.
Based on the given scenario,the transport of glucose is accomplished through diffusion.
What is diffusion?
Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.
