Name three components of the cell membrane and explain how each contributes the semipermeable nature of the membrane.
The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates. The plasma membrane protects intracellular components from the extracellular environment. The plasma membrane mediates cellular processes by regulating the materials that enter and exit the cell.

Lungs are the parts of the body where the exchange of the gases are taking place. The exchange of the gases takes place at the alveoli.
What is the cavity in which the lungs are present in ?Lungs are present in the pleural cavity.
Our body is constituting a pair of lungs that is the right lung and the left lung and inside a lung fluid is present which is called as pleural fluid that is present in order to make the structures safe and sound. 1. Left lung 2. Right lung.
3. It is the point at which the bifurcation of the trachea is being done. 4. It is the inferior lobe of the lungs. Basically , the inferior lobes of lungs absorb their lymphatic fluid towards the inferior tracheobronchial nodes . On the other thing, superior tracheobronchial nodes absorb out lymphatic fluid from upper lobes.

Answer:
more active transport occurs in cell A then cell B
Explanation:
hope this helps ;)
The possible conclusion that can be made drawn about the activity of these two cells is that more active transport occurs in cell A than in cell B. The correct option is B.
What is transport?Active transport is a type of transport that cells use to move molecules up and down cell membrane concentration gradients.
Moving actively is carried out using a variety of membrane proteins known as carrier proteins that are connected to an energy source, such as ATP, for example.
The energy needed to move molecules or ions up or down a concentration gradient is provided by the hydrolysis of ATP during this process, known as active transport. The other transport is passive transport, which is reverse.
Therefore, the correct option is B. more active transport occurs in cell A than in cell B.

[tex] \huge \bf༆ Answer ༄[/tex]
The acceleration produced by that boy is Zero .
_____________________________________
Want to know how ? here's the reason : -
As he is running with a constant velocity, so there's no change in velocity and Acceleration is defined as " Rate of change in Velocity " and since there's no change in velocity and direction (because he is moving in a straight road) hence Acceleration is 0.

why is the digestive tract of the frog well vascularized
The digestive tract of the frog is well vascularized because it aids in the absorption of nutrients.
The digestive tract of a frog is a hollow long tube that extends from the mouth to the anus which helps in the ingestion and digestion of food.
The digestive tract of frog has the following characteristics:
alimentary canal of the frog is not long, that is, it is short. It has accessory organs of digestion such as liver, gall bladder and pancreas.All the digested food substances are absorbed at the small intestine due to the presence of microvilli.
This microvilli is made up of a central core that is vascularized, that is, it contains artery, vein and lymphatic capillary.
Therefore, the vascularized microvilli of the small intestine of frog help in the absorption of nutrients.

Got it right on exam :)
Particulate matter is defined as material emitted during manufacturing that does not change form in the atmosphere and is a primary pollutant from a stationary source. The correct option is a.
What is particulate matter?One of the least evident types of pollution is particulate particles. NOT the case for pollution from particle matter. Particle pollution, commonly known as particulate matter (PM), is a type of air pollution made up of microscopic fragments of solids or liquids.
Dust is one possible type of these specks. Dirt. Soot. Particulate pollution can exacerbate acid rain while also altering weather patterns, causing drought, accelerating global warming, and causing the ocean to become more acidic.

D. Student 4: Golgi Bodies sort and package lipids which the Endoplasmic Reticulum uses to make proteins.
Answer:
Letter D. Golgi Bodies sort and package lipids which the Endoplasmic Reticulum uses to make proteins.
The student that provides the best explanation is as follows:
Student 3: Chloroplasts produce simple sugars which mitochondria use to provide energy for the cell.What is Cellular Homeostasis?Cellular homeostasis may be defined as the capability of a cell in order to maintain relative stability and function as alterations take place in the internal or external environment.
According to the question, the Lysosomes are the fatal or self destrcutive bags for living cells. Vacuoles store nutrients as well as waste substances of the whole cell in order to prevent cells from being contaminated.
The sorting of important molecules like lipids and proteins is initiated through the endoplasmic reticulum and proceeds to the Golgi bodies through the anterograde pathway.
While the photosynthetic organelle chloroplast captures the radiation energy from the sun and synthesizes simple sugar like glucose which is used by another organelle mitochondria to provide energy for the cell.
Therefore, the correct option for this question is C.
