Thee drying of the surfaces of the eye, including the conjunctiva, is called:

Answers

The answer is called Xerophthalmia. Hope this helps.

The drying of the eye surfaces, including the conjunctiva, is consistent with dry eye syndrome, not conjunctivitis. Conjunctivitis, instead, involves inflammation and can cause redness, irritation, and vision issues.

The drying of the surfaces of the eye, including the conjunctiva, is not specifically named in your reference, but it typically relates to a condition called dry eye syndrome or keratoconjunctivitis sicca, which is not the same as conjunctivitis. Conjunctivitis is an inflammation of the conjunctiva, which is the mucous membrane covering the eye and the inside of the eyelid. This condition can cause redness, irritation, blurred vision, and sensitivity to light. In severe cases of conjunctivitis, progressive corneal scarring can occur, potentially leading to blindness. The conjunctiva is also a common entry site for pathogens causing infections. These infections can be in different forms, such as acute purulent conjunctivitis with pus formation, acute hemorrhagic conjunctivitis with bleeding, or other related infections such as blepharitis (inflammation of the eyelids) and keratitis (inflammation of the cornea).

during diffusion, how do the molecules physically get from one place to the other? (spaceship tractor beam, winged monkeys)

Answers

Molecules move from high concentration to low concentration depending on passive or active transport. Active transport is when the nutrients are actively moving out of the cell and passive is when the nutrients or ‘molecules’ are going into the cell this is because cells have a semi permeable surface. Only letting in specific molecules.

During diffusion, molecules move from the region of higher concentration to the region of lower concentration.

For diffusion to occur, there must exist a diffusion gradient which is the difference in the concentration of the substance in the two regions.

Therefore, the diffusion gradient is the driving force that allows diffusion to take place.

Some characteristics of diffusion include:

Diffusion is rapid when the concentration gradient is large.It slows down when the difference in the concentrations become less.When the molecules (solute) are evenly distributed in the medium (solvent), we say a dynamic equilibrium has been reached.

Adults often provide indirect feedback about grammar by using __________, which restructures inaccurate speech into correct form.
a.fast-mapping
b.an expansion
c.overregularization
d.a recast

Answers

Recasting (d) is the correct answer. By doing this, the errors are corrected, yet the flow and general communication is not obstructed. The adult (or other person) will simply restate the proper grammatical form to the learner before continuing the conversation.

Final answer:

Adults often use a recast to provide indirect feedback on grammar, subtly correcting a child's speech by incorporating the correct form in their response. This method allows children to learn the proper usage through exposure in a natural conversational context. It contrasts with overregularization, where children apply grammatical rules too broadly, demonstrating the refining role of recasts in language acquisition. The correct option is d.

Explanation:

Adults often provide indirect feedback about grammar by using a recast, which restructures inaccurate speech into correct form. This method involves adults responding to a child's incorrect utterance by subtly correcting the mistake within their reply, without explicitly pointing out the error or demanding correction from the child. For instance, if a child says, "I goed to the park," an adult might respond, "Oh, you went to the park? That sounds fun!" Here, the adult is not directly correcting the child but providing the correct form of the verb. This technique is beneficial because it models the correct usage in a natural context, helping the child to internalize the correct form through exposure rather than through direct correction.

Recasts contrast with approaches like overregularization, where children apply general grammatical rules too broadly, leading to errors. While overregularization reflects a child's growing understanding of language rules, recasting helps to refine this understanding by providing correct models in response to mistakes. For example, overregularization might lead a child to say "foots" instead of "feet," and an adult might use a recast by saying, "Yes, your feet look cold."

Which property of water explains its ability to prevent sudden changes in body temperature?

Answers

(High) Heat Capacity

Heat capacity is the amount of heat needed to raise the temperature of a substance by 1 unit degree (Celsius, Kelvin, Fahrenheit, Rankine). 

Water has a relatively high heat capacity, which means that it would have to absorb relatively large amounts of heat before it could actually have a large change (i.e. increases) in temperature. Conversely, it would have to give off a lot of heat in order for it to cool down.

The heat capacity of 1 gram of water is 4.184 Joules/°C, which means that 1 gram of water needs 4.184 Joules of heat to increase its temperature by 1°C. In comparison, 1 gram of copper only needs 0.385 Joules to raise its temperature by 1°C, which means that copper heats up by about 10 times more than water when subjected to the same amount of heat.

Herb:bigger molars and become taller for higher plants
Carn:bigger fangs(teeth) grow more broader and faster to chase prey

Answer: Herbivores eat more often and carnivores eat less often.

Explanation:

The different adaptations for obtaining food in case of herbivores and carnivores is that herbivores eat more often as compared to carnivores.

The herbivores are the animals that feed on the plants and trees, fruits for their survival.

The carnivores are the animals that eat flesh of other animals and that is the reason carnivores eat less often because it takes time to digest the flesh.

What is the product after the animal is harvested called?

Answers

Final answer:

After an animal is harvested, the product is often called meat, or in case of wild animals, 'bush meat'. Other byproducts of harvested animals include dairy, hides, and hooves, which are used for food and other industries. The rising human population and increased demand for protein foods raise the need for sustainable animal harvesting.

Explanation:

The product after an animal is harvested is generally referred to as meat. In certain cases, such as with wild animals, this is often referred to as bush meat, particularly in equatorial Africa and parts of Asia. This includes mammals and many primates living in the Congo basin. However, hunting and the commercialization of bush meat has increased harvest rates, threatening a number of species with extinction.

On a more sustainable and commercial level, harvested animals from both pastoralist and agricultural practices yield products like meat, dairy, and fish, as well as byproducts like hides, hooves, and sometimes even their dung for fuel. These products find their way into human consumption or are used in various industries.

The growing human population and the increasing demand for protein foods has further amplified the need for these animal products. However, the dependency on animal-based resources significantly impact the environment, prompting the need for more sustainable food production and distribution systems to meet future demands.

Suppose we discovered a form of life like our own which utilized 20 amino acids, but had 6 nitrogeneous bases instead of the 4 our life uses. what would be the minimum length of a codon which could represent all 20 currently used amino acids?

Answers

The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.

Once the body has begun shivering, what happens to make it stop shivering?

A) When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shivering.

B) When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shivering.

C) When body temperature is below normal, the nervous system sends a message to the skeletal system to stop shivering.

D) When body temperature is below normal, the respiratory system sends a message to the muscular system to stop shivering.

Answers

I believe the answer is D. Hope this helps ;D

Answer: Option B

Explanation:

When the body is exposed to the colder temperature then it starts shivering and this response is the part of homeostasis. During this process the nervous system sends signal to muscular system which stimulates shivering to make the body temperature normal.

When the body temperature comes to normal again the nervous system sends a signal to muscular system to stop the shivering.

Thus, the correct answer is "Option B".

SCIENCE!!! HHHEEELLLPPP!!!
Are viruses alive? This a question debated among scientists throughout the world.

Scientists discovered the tiny, disease-causing agents that were believed responsible for such diseases as rabies and hoof-and-mouth disease. Initially, scientists classified viruses as “living”, but in 1935, they began to change their thinking.

Scientists crystalized the tobacco mosaic virus, noting that it did not have cell structure, of even the simplest kind. There was no membrane, no nucleus, and no ribosomes. They determined that a virus was nothing more than a strand of nucleic acid, DNA or RNA, protected by a protein shell. Scientists also believed that viruses lacked the mechanisms necessary for metabolic function.

Some scientists argued that viruses are capable of response to stimuli. When not in a favorable environment within a host cell, the virus remains an unchanging, dormant, organic particle. But once in contact with the susceptible host or in a favorable environment, the virus becomes active, injecting its nucleic acid into the host cell, and eventually self-replicating. In this manner, one virus is capable of producing many other viruses, identical to the original, to attack host cells.
