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.

Hence , the correct option is B.

Answer: D. the Cell wall

Explanation: The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.

Also it is also a ridged layer found outside of the cell membrane

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.

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.

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.

Answer: Animals and plants are made of cells. Tissues are made from cells of a similar type. Organs are made from tissues, and systems are made from several organs working together.

Explanation:

Answer:

In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems.

A fair amount of the world's precipitation falls as snow or some other solid water form. Actually, outside the tropical regions, it is likely that the much of the precipitation begins in the solid form and only becomes liquid rain when it melts while falling through air with temperatures above freezing.

Answer:

Violating 'Ceteris Paribus' {Other factors constant} assumption, as both food & space are varied (simultaneously)

Explanation:

Weight Growth is the dependent (effected) variable in this case. And, independent (causal) variables are food amount are living space respectively.

However particular independent factor's (food or living space) impact on dependent variable ie weight growth : can be determined only by - examining individual variable (food or living space) impact on weight growth. So, either of the two variables should be varied, & not both should be varied simultaneously.

This would imply depiction of each factor's clearer individual impact on the dependent factor.

Answer:

be durable

Explanation:

From the scenario described the Engineers have met one of the main criteria which is for it to be durable. A design needs to be made with a material that is available, durable, and cheap in order for it to be as efficient as possible while also selling and being profitable. By finding the material polycarbonate they have made sure that the design will be durable as well as cost-efficient since the material is "not too costly". Now if they are able to acquire the material in large quantities then they would have met the availability criteria as well.

Answer:

Each skull has a large diastema, or gap between the front and back teeth. 2. What is the biggest change in skull anatomy that occurred from the dawn horse to the modern horse? The size of the skull is dramatically larger in the modern horse.

Explanation:

The main change in skull anatomy that occurred from the dawn horse to the modern horse is that the skull of the modern horse is dramatically larger.

Eohippus, (genus Hyracotherium), also called dawn horse, an extinct group of mammals that were the first known horses. They flourished in North America and Europe during the early  Eocene (56-33.9 million years ago).

Eohippus, "dawn horse" or more correctly called Hyracotherium, which lived in the Eocene approximately 55-58 million years ago, is the oldest ancestor of the modern horse.

Hyracotherium, or eohippus (dawn horse), as  scientists called it, first appeared on earth as a small, shy creature no bigger than a dog. It existed between 55 and 5 million years ago.

Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.

Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.

The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.
