Answer:
Epithelial tissue covers body surfaces that are exposed to the environment and also secretes internal regulatory molecules
Explanation:
The epithelium is one of the four main classes of animal tissues (i.e., epithelial, muscle, connective and nervous tissues). The epithelial tissue covers both external and internal body surfaces such as, for example, the skin and the digestive tract, respectively. In the skin, this tissue is a protective layer that prevents water loss and damage by external environmental factors or by mechanical friction. Moreover, in the digestive tract, epithelial tissue plays critical roles for the absorption of nutrients, as well as during regulation and excretion of hormones.

Answer:
[tex] \huge \boxed{ \mathbb{ \bold{ \purple{ \: cell}}}}[/tex]Explanation:
All the living organisms on this Earth are made up of microscopic units called cells. It is basic structural unit for all the organisms. The cells are the building block of all the living organisms. Our body is composed of trillion of cells. They carry out the functional activities of our life. A cell can be defined as a basic , structural and functional unit of life capable of independent existence. The cell was first discovered by Robert Hooke in 1665 AD. As we know that all the living organisms are made up of cells. These cells are developed as a result of a division of pre-existing cells. All the cells are same in chemical composition and metabolic processes. The function of an organism as a whole is the outcome of combined activities and interactions of the constituent cells. The cell is known as the fundamental , structural and functional unit of life.

Devon is playing with a yo-yo. A yo-yo has an axle in the middle of two plastic halves. A string is tied around this axle. As Devon moves his hand, the yo-yo goes up and down. The yo-yo converts potential energy to kinetic energy as it moves. Which of the following pictures represents the yo-yo with the most potential energy? A. X B. Y C. Z D. W
Answer:
second image or B. Y
Explanation:
Potential energy is defined as the stored energy of an object when work is done against a force.
The second image in which yo-yo is ready to stretch out, represents the yo-yo with the most potential energy because the distance is highest from the ground and so yo-yo at this position will have highest gravitaional potential energy. The potential energy will be converted into kinetic energy when released in air.
Hence, the correct image is "second image" or "B. Y"

From where digestion of carbohydrates begins
Answer:
it begins in the mouth
Explanation:
when we chew food, salivary amylase in the saliva starts the breakdown of carbohydrates.
There you go! (＾▽＾)
[tex] \LARGE{ \underline{\underline{ \sf{\pink{Required \: answer:}}}}}[/tex]
The digestion of carbohydrates or sugars starts from the Buccal cavity (or mouth) itself because of the salivary amylase secreted by the salivary glands.
There are three pair of salivary glands which release saliva that helps in the partial digestion of carbohydrates. The food is first masticated by the teeth with the help of tongue and slowly digested partially.

Match each type of cell junction with its description.
Tight junctions
*prevent liquid from seeping between cells
Desmosomes
*act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions
*allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata
*openings through the cell walls of plant cells that allow adjacent cells to share materials
Answer:
Tight junctions - prevent liquid from seeping between cells
Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials
Explanation:
1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.
2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.
3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.
4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.

In a nutrient medium that lacks histidine, a thin layer of agar containing around 10^9 Salmonella typhimurium histidine auxotroph produces around 13 colonies over a two day incubation period at 37 degrees centigrade. How do these colonies arise in the absence of histidine? The experiment is repeated in the presence of 0.4 micrograms of 2-aminoanthracene. The number of colonies the number of colonies produced over 2 days exceeds 10,000. What does this indicate about 2- anthracene? What can you surmise about its carcinogenicity?
Answer:
Reverse mutations in the colonies enabled to recover the ability to synthesize histidine. The 2-aminoanthracene is a chemical agent that induce mutations and therefore it is potentially a carcinogen.
Explanation:
A reverse (suppressing) mutation is a type of mutation capable of restoring the activity of previously mutated genes. On the other hand, 2-aminoanthracene is an aromatic amine carcinogen capable of inducing hepatic and skin tumors. In this case, 2-aminoanthracene has been used to induce reverse mutations at loci responsible for the synthesis of histidine.

The cell bodies of motor neurons to skeletal muscles are located in the A. Posterior/dorsal gray horns B. Limbic system C. Anterior/ventral gray horns D. Gray commissure
The cell bodies of motor neurons to skeletal muscles are located in the anterior/ventral gray horns.
Neurons are cells characterized by a body (called soma), and different kinds of prolongations that will have the task to carry the information to other neurons or tissues - these prolongations are axons (which are usually very long) and dendrites (much shorter than axons).
The motor neurons are the ones that conduct the electric impulse from the motor cortex in the brain to the skeletal muscles in our bodies, making muscle contraction and movement possible.
There are two types of motor neurons:
Upper motor neurons: Their cell bodies are located in the motor cortex in the precentral gyrus of the brain. Their axons synapse onto interneurons in the spinal cord.Lower motor neurons: These neurons have their cell soma located in the anterior gray horns of the spinal cord - from that place, their axons will exit the spine to reach the skeletal muscles that we want to contract to perform specific tasks such as running or grabbing a glass of water.Thus, we can conclude that the somas of lower motor neurons that transmit its impulse to skeletal muscle are located in the anterior gray horns of the spinal cord.

The majority of thyroid hormones are secreted as ______but small amounts of _____is also secreted from the follicle.
Answer:
The correct answer is - T4, and T3.
Explanation:
The Thyroid glands are butterfly shape glands madeup of microscopic spherical structures known as thyroid follicles made up of cuboidal follicular cells. These cells produces the both major hormones of thyroid gland T4, and T3.
The majority of thyroid hormones are produced as T4 hormones approximately 80% but a small amount of 20% is released in the form of T3 hormones. However, the most active form of the thyroid hormone is T3 and to act on target cells, one iodine molecule have to be removed to convert T4 to T3.
What is 0.55 hectometers expressed in decimeters?
550 dm
b. 5.5 dm
c. 55 dm
d. 0.00055 dm
Answer:
A 550
Explanation:
0.55 hectometers is equivalent to 550 decimeters.
Since 0.01 hectometers and 10 decimeters (1 meters) are both equal to one meter, :550 decimeters (55 meters) are equal to 0.55 hectometers. Thus, option A is correct.
What are hectometers and decimeters?
The International System of Units (SI) defines the hectometer (International spelling as used by the International Bureau of Weights and Measures; SI symbol: hm) or hectometer (American spelling) as a unit of length that is equal to 100 meters and one tenth of a kilometer.
The ruler, which is 12 inches (0.3 m) (in) or 30 centimeters (cm) long and equals one foot or slightly under one-third of a meter, is visible. 100 meters make up a hectometer.
To produce one hectometer or 328 feet (99.97 meters), that would need about 328 rulers. That is a lot of rulers, I must say. Here is a simpler method for recalling a hectometer's length.
Decimeter measurements are uncommon in everyday life. It is simpler to use 0.1 m or 0.5 m when the length is less than a meter because one meter is not a particularly length.
Therefore, 550 decimeters (55 meters) are equal to 0.55 hectometers.
