What IS brain-freeze?
It is a severe pain for a short period of time in the brain due to sudden decrease in temperature of the mouth upper part .
The upper part of the mouth contain the capillary of the sinuses with got stimulate by a cold food or air which results in vasoconstriction .
For stopping the pain we just need to warm the capillaries which causes the vasodilation which in returns stops the pain
Another Reason For Brain Freeze:-Sphenopalatine ganglioneuralgia nerves ( SPG) also the nerves near the trigeminal nerves in the brain . This nerves carry impulse form the nose to the brain . These nerves are highly sensitive to pain , temperature,etc so there r basically to prevent brain from pain , temperature etc .
In result from the stimulus the brain starts a severe pain which we called the brain freeze .

NUCLEIC ACIDS:
Nucleic acids are one of the biomolecules. They are polymeric molecules made up of monomeric units called nucleotides. Several nucleotides come together to make up nucleic acid, which can either be DNA or RNA. A nucleotide monomer is made up of three components namely: nitrogenous base (A, C, G, T), a pentose (5-carbon) sugar, and a phosphate group. Therefore, the components that make up each nucleotide monomer in the nucleic acid in the image is as follows: a five carbon sugar, a phosphate group, and a nitrogenous base.Learn more at: https://brainly.com/question/908854?referrer=searchResults

Dr. Smith performed an experiment to test how the temperature in which tulips are kept affects their growth. To do this, she planted groups of young tulip plants in four different areas and kept each environment at a different temperature. These temperatures were 10°C, 15°C, 20°C, and 25°C. After a month, Dr. Smith determined the average growth of the plants in each group. Dr. Smith's experiment showed that the tulip plants grew the most at 20°C and grew the least at 15°C. They didn't grow at all at 10°C. Use the drop-down menus in the table to select the values most likely recorded by Dr. Smith. Each value will be used only once.

What is a protein that is the main component of the thick filaments in muscle fibers and is responsible for muscle contraction? actin myosin atp dna
The protein that is the main component of thick filament is myosin.
What is the function of myosin?
Myosin belongs to a superfamily of motor proteins that play roles in muscle contraction and in a wide spectrum of other motility processes in eukaryotes.
The prototype of a molecular motor is a protein that converts chemical energy in the form of ATP to mechanical energy, thus developing force and movement.
Thus, myosin is a thick filament.

One student filled two clean jars with hot water. Baking soda was added to water in both the Jars and stirred until no more baking soda dissolved in the water. Small
weights were tied to two ends of a thread and the ends were dipped into the two jars as shown below.
After two or three weeks the student observed a white solid material growing down from the middle of the thread between the two jars. The student's experiment demonstrates
that
A) Wmen water evaporates, it leaves solid minerals behind
B) When water is left undisturbed, it turns into solid minerals
C) when water reacts with baking soda, it freezes into solid minerals
D) When baking soda reacts with water, it converts gases into minerals
Answer:
A
Explanation:
Heated water will hold a higher amount of dissolved material than cooler water. As water evaporates the amount of dissolved material that can stay dissolved decreases. What cannot remain dissolved precipitates onto a point of nucleation. In this case the string.

What two chemicals are used to test for carbohydrates?
Answer:
Iodine and Sulfuric Acid.
Explanation:
During Molisch's test, Sulfuric Acid is used to judge whether or not a carbohydrate is present, and, if so, a purple ring will appear. In the iodine test, iodine is used to confirm starch is in the carbohydrate, and will alert you with a blue ring appearing.
Answer:
In the presence of starch, iodine turns a blue/black color. It is possible to distinguish starch from glucose (and other carbohydrates) using this iodine solution test. For example, if iodine is added to a peeled potato then it will turn black. Benedict's reagent can be used to test for glucose.

Why do invasive species
disrupt ecosystems?
A. They can outcompete native species.
B. They cannot be killed by any of the
organisms in the environment.
C. They enhance the environment they
оссиру.
Answer:
A. They can outcompete native species.
Explanation:
Remember that ALL species need an ecosystem they can easily adapt in to survive, especially invasive ones. Adaptation is a heritable trait that helps organisms adjust to new changes in their environment.
Invasive species can compete with native organisms for resources, cause extinctions, reduce biodiversity, and disrupt ecosystem processes. They can also threaten, or even prevent human use of the resources in the ecosystem.
In order for an invasive species to be successful in their new environment, they need to be able to reproduce and grow rapidly to take over quickly.

Inflammatory responses typically include increased activity of phagocytes in an inflamed area.
inhibiting the release of white blood cells from bone marrow.
release of substances to decrease the blood supply to an inflamed area.
reduced permeability of blood vessels to conserve plasma.
clotting proteins migrating away from the site of infection.
Macrophages are cells from the immune system that recognize and eliminate strange elements. Option A. Inflammatory responses typically include increased activity of phagocytes in an inflamed area.
What is macrophages function?
Macrophages are one type of white globules involved in the organism's defense against strange substances and pathogen agents. They are the principal actors in the immune response.
Macrophages recognize different strange molecules that penetrate the organism (bacterias, parasites, and viruses), phagocyte and eliminate them. This process known as phagocytosis.
When macrophages are activated, they release cytokines that favor inflammation response, neutralizing the pathogen agent and removing damaged tissue from the affected area.
Together with inflammation, there is a change in blood flow, increasing the permeability of blood vessels, and enhacing the migration of fluid, proteins, and other immune cells to the affected area.
The correct option is A. Inflammatory responses typically include the increased activity of phagocytes in an inflamed area.

Label : The purple lines represent a characteristic change, or adaptation . ... The “parsimony score” calculates how many changes occur in a given cladogram.
Explanation:
A cladogram shows how species are related by descent from a common ancestor. A classification of organisms on the basis of such relationships is called a phylogenetic classification.
A phylogenetic classification involves organisms in a clade with their common ancestor.
How organisms are related in cladogram?A cladogram consists of an organism being studied, lines, and nodes where those lines cross. The lines represent evolutionary time or a series of organisms that lead to the population.
A clade is a group of living organisms and the common ancestor they are derived from.
