Answer:
The least numerous but the largest of the papillae are arranged as a V-shape on the posterior dorsal surface of the tongue. They contain the majority of taste buds and are called vallate papillae.
Explanation:
The shape, location and function of these taste buds make vallate papillae unique. First, they have a distinctive "v" shape, and most adults only have seven to twelve of these papillae, vallate papillae are the least numerous papillae, they are the recipients of the bitter taste. The vallate papillae are the largest and the most specialized, they are located on the back of the tongue, forming the lingual V, in a variable number from 7 to 12. The number of taste buds depends on age, presenting around 270 in the newborn and descending approximately one hundred in individuals older than 75 years. These buttons are located in the crypts or grooves that form the papillae, mainly on their internal face (the annular groove is observed between the papilla and the edge of the calyx), in whose edges the extremities of the taste corpuscles stand out in the form of filaments. Each taste corpuscle comprises two classes of cells: supportive and taste cells.
The largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.
Vallate papillae:
These are specialized taste buds that present in the posterior dorsum of the tongue.
They are the largest taste buds. They form a 'V'- shape structure.There number can vary between 7- 12.Therefore, the largest but least numerous papillae in the dorsal surface of the tongue is Vallate papillae.

A student collected samples of cells from a woody plant during the spring and produced the drawings below. Sample 1 was collected from the woody stem of the plant. Sample 2 was collected from the root tip of the plant. Cells in different steps of mitosis are labeled with letters A, B, C, D, and E in Sample 2. Describe the role of mitosis in the growth of a plant.
The provided question is incomplete, however, the question asked is a very generalized question, answering it on the knowledge of mitosis.
Answer:
The correct answer is - mitosis has a great role in the growth of plants.
Explanation:
Mitosis is a type of cell division that occurs in the somatic cells of an organism. During mitosis, a parent cell divides into two daughter cells with the same number of chromosomes. There are no recombination takes place. This type of cell division is fast.
Mitosis occurs during asexual reproduction in the form of budding, propagation as well as repairing of the cells as they are fast, such as the regeneration of new cells. The growth of plants and development is dependent on mitosis as they produce cells more efficiently and fast and mitosis is the only cell division found in somatic cells.
Breathing heavily after running a race is your body's way of *
a. restarting glycolysis.
b. recharging the electron transport chain.
c. repaying an oxygen debt.
d. making more citric acid.
Answer:
The correct option is C.
repaying an oxygen debt.
Explanation:
This is because while running, humans breath shallowly which could not provide the oxygen requirement for the respiratory system and fit in for blood need.
After running, you tend to breathe heavily because your muscle work very hard , the body use more oxygen and produced more carbondioxide, therefore the lungs and respiratory system must try to provide more oxygen to the blood. sympathetic nerves stimulate respiratory muscles
so as to increase the rate at which we breathe.

Collagen diseases are a group of human diseases in which the production of collagen throughout the body becomes impaired. Some examples of collagen diseases include systemic lupus erythematosus (SLE or lupus), rickets, and osteogenesis imperfecta. Explain why these diseases often affect the entire body. Hint: Consider the distribution of connective tissue throughout the body.
Answer:
Explanation:
Collagen vascular disease is group of disease that affects the connective tissue.
Collagen is a protein based connective tissue that includes collagen and Elastin.
Collagen is found in the tendons, ligaments, skin, cornea, cartilage, bone and blood vessels while Elastin is a stretchy and formed the major component of ligaments and skin. This connective tissue holds, protect and connect and bind various body structures together both bones, ligaments, and muscles together. When a patient then has a connective tissue disease, the collagen is affected, the elastin are inflamed and every structure connected to the proteins in the body parts are harmed.
Paheli would like to suggest that containers used for the storage of poisonous materials should be recycled separately, such that recycled plastic is not used to make plastic bags. do you agree with this why
Answer:
Yes, I agree
Explanation:
This is because these storage containers and plastic contain some poisonous chemicals which are dangerous or harmful to living organisms and the environment.
When these chemicals get into the human bodies, they can cause health hazards and when they are washed into the aquatic bodies they can kill aquatic lives. Even if these chemicals are washed in animals drinking water, they can affect the animals negatively.

Why did you not see any chloroplasts in the onion epidermal cells, unlike in the Elodea (Anacharis) cells?
-Chloroplasts in onion cells are hidden by the large central vacuole.
-The part of the onion viewed under the microscope grows underground.
-The purpose of chloroplasts is to make the plant green but onions are not green.
-Chloroplasts are organelles that absorb sunlight energy and perform photosynthesis.
-Plant parts that grow underground are not exposed to sunlight.
-Onions had chloroplasts before they were picked from the ground but the chloroplasts dried up and disappeared after being exposed to the sunlight.
-Onions are not plants and therefore do not have chloroplasts.
-Plant parts that are not exposed to sunlight cannot do photosynthesis.

For a specimen of an active motile microorganism, the most effective microscope for visualization would be the phase contrast microscope.
The phase contrast microscopy is a technique designed to make images of live, colorless, and transparent microbes visible by enhancing the contrast. Most light microscope requires that microbes are killed and stained before they can be visible. The phase contrast technique uses optical mechanism such that any slight variation in the phase of the organism leads to a change in amplitude and can be seen in the contrast of its image under the microscope.In summary, the phase contrast microscope would be the most effective microscope to use when a live microbe specimen is in question due to the fact that it would use a phase change to create an enhanced image without having to kill or stain the microbe.

Answer:
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Why are phospholipids of the plasma membrane oriented such that their heads are at the membrane surfaces and their tails are buried in the interior of the membrane?
Answer:
The plasma membrane is semi-permeable. The reason for this is because of the orientation of the phospholipids. The heads at the surface are hydrophilic so they face the water. The tails are hydrophobic so they face away from the water.
Explanation:
The phospholipids of the plasma membrane are oriented such that their heads are at the membrane surfaces and their tails are buried in the interior of the membrane - due to the fact that phospholipids have hydrophobic tails and hydrophilic heads.
Phospholipids consist of fatty acids and alcohol in the plasma membrane are arranged in two layers, known as the phospholipid bilayer. It has a hydrophobic or water-hating tail and a hydrophilic or water-loving head.
it has a head and two tails.As the tails are hydrophobic so, face the inside, away from the water.As the heads are hydrophilic so face outwardHeads are towards intracellular and extracellular fluid.Tails are meet the inner layerThus, the correct answer is - due to two layers of hydrophobic tails and hydrophilic heads.

But I've had chargers that I spilled water on and they still work fine, but again, it depends. Like if there's a tear in the cord that liquid got in, then no it probably won't work anymore.
