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.

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.

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.

The receptors that aid in allowing a person to maintain balance are located within the inner ear.
The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.
The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.

Pls mark as BRAINLIESTDoes venueles carry bright red color?
Answer:
No
Explanation:
Arteries typically carry oxygenated blood, which is bright red in colour. The exception is the pulmonary artery which carries deoxygenated blood from the heart to the lungs.
Answer:
Venules carry deoxygenated blood. All blood in humans is bright red when oxygenated, but, a darker red when deoxygenated. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).

OSMOSIS:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane. Osmotic principle is based on concentration gradient i.e. difference in concentration across a membrane.

Pulse: 60 to 100 beats per minute.Vital signs are measurements of the body's most basic functions. The 4 main vital signs routinely checked by healthcare providers include: Body temperature. Pulse rate.Checking vital signs is an important skill to learn, because it tells us how the person's body is functioning, helping us to monitor current conditions and alerting us to changes in health status.

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
