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.
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.

which statement regarding normal microbiota of the human respiratory system is false?
Given what we know about the respiratory system, we can confirm that the statement regarding normal microbiota of the human respiratory system that is false is option B " The upper respiratory tract is mostly sterile".
As far as the human respiratory tract and system, it was previously believed that the upper tract contained bacteria while the lower respiratory tract was sterile. Recently, however, this has been proven to be false. Bacteria are in fact present in the entire respiratory tract even in healthy individuals. For this reason, options a, c, and d are true, and the only false option present is b.
This question was answered based on the complete question found online that states:
Which statement regarding normal microbiota of the human respiratory system is FALSE?
a) The trachea normally may contain a few bacteria.
b) The upper respiratory tract is mostly sterile.
c) The ciliary escalator in the bronchial tubes keeps the lower respiratory tract nearly sterile.

Explanation:
A group of students was asked to explain how one organelle in a plant cell directly supports the work or
another organelle to maintain cellular homeostasis. Which of the following students provides the BEST
explanation?
A. Student 1: Lysosomes supply amino acids which ribosomes use to build proteins.
B. Student 2: Vacuoles store genetic information which are used to construct the cell wall.
C. Student 3: Chloroplasts produce simple sugars which mitochondria use to provide energy for the cell.
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.

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.

What differences are there in the growth of the human population compared to the animal/plant population?
Answer:
Explanation:
In both plants and animals, there are parts of the body designed to carry the nutrients needed for growth. In a animal it is blood and in a plant, it is the Xylem and Phloem Tissue Humans are born with a set number of limbs and if one get's cut off it cannot regenerate. Because of this, we are increasingly cutting into resources that other species must use in order to survive. We have hindered, or even ended the lives, of numerous species. Today, 99% of the species still remaining on this planet are at risk because of human activity alone.The similarities in the population growth of humans with respect to plants and animals is that, in the three cases, the growth occurs exponentially with respect to the initial number of specimens

Answer:

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.
