To show that cow milk contains protein and different types of carbohydrate,food tests should be carried out by the student.
Carbohydrates (sugars) are the main sources of food through which the body derives energy from.
The various types of carbohydrate are the simple sugars, complex sugars and starch.
Proteins are the main body-building substances which are necessary for the maintenance of health.
The cow milk contains proteins and a type of carbohydrate called lactose which is an example of complex sugar.
To test for protein in milk, xanthoproteic reaction test should be carried out by the student. The procedure includes:
To the milk solution add a few drops of concentrated nitric acidA white precipitate forms, which turns yellow on heating.Cool the contents and add a few drops of ammonia solution.The colour of the precipitate deepens to yellow indicating presence of protein in the cow milk.To test for carbohydrate in milk, a test for complex sugar should be carried out by the student. The procedure includes:
Add milk solution and hydrochloric acid into a test tube. Place the test tube inside a boiling water-bath.The acid hydrolyses the complex sugar to simple sugars.Fehling's test is then carried out on the simple sugars that are formed which are glucose and galactose.An orange-red precipitate indicates a positive result.Learn more here:

This graph is showing how different rates of light intensity, environmental temperature, and Carbon dioxide affect the rate of photosynthesis. It looks like the greatest rate of photosynthesis has .13% Co2 at 30 degress celsius.
Explanation:
I was always taught that they y-axis is the dependent variable and going off that, all the other variables can be controlled and changed.
James adds some magnetic marbles to a glass jar full of ordinary marbles, and then shakes up the jar. What do you think will happen to the magnetic marbles?
Answer:
Magnetic marbles will tend to attract each other.
Explanation:
Magnetic marbles are composed of ferromagnetic materials, which indicates that they function as a magnet and have the ability to attract other objects formed by ferromagnetic materials. In this case, we can say that the magnetic marbles attract each other and inside a jar containing magnetic marbles and common balls, the magnetic marbles will tend to attract and group together.
When James shakes the glass jar ; The magnetic marbles will attract each other
The magnetic marbles will attract each other because of the ferromagnetic materials that each magnetic marble contains. marble is a rock ( metamorphic ) that is made up mainly of calcium carbonate .
when rocks/compounds contain ferromagnetic materials they will act as magnets thereby attracting any metallic object or any magnetic material within close proximity. therefore the magnetic marble will attract each other inside the glass jar
Hence we can conclude that When James shakes the glass jar ; The magnetic marbles will attract each other.

Name two ways that atoms can combine to become more stable in compounds
Answer:wo processes by which elements can combine to form stable compounds are transferring electrons from one atom to another (ionic compounds) or by sharing electrons (covalent compounds).
Explanation:
i had that question before:)
Answer:
Covalent bonding and Ionic bonding.
Covalent bonding is when atoms share electrons in order to form a stable electron arrangement. The two positive nuclei are attracted to the positive shared electron which holds the molecule together.
Ionic bonding is a giving and accepting of electrons between a metal and non metal. A metal will give the non-metal one or more electrons in order for both to form a stable electron arrangement.
Explanation:
Why do people believe in false claims?
Answer:
Becuase everyone has different beliefs and some also can be more concieveing than other aslo meaning the ones that are very easily influenced will believe you toward the not so influenced people will also do research and stuff like that. Therefore, some fasle claims are believed.
Explanation:
Fennec foxes (desert foxes) have ears up to 15 cm long. Thousands of years ago there was huge
variety in the size of the ears. Over time, those with the biggest ears were able to better survive as
they can lose more heat in the hot summer months. What would you expect to happen to the length
of Fennec fox ears if the temperature in the desert increases?
Answer:
You would expect their ears to also increase in size.
Explanation:
As the question says the ones with the biggest ears survived the best, implying if the temperatures rose the length of the ears would as well so that they could give off body heat.
All proteins have amino acids as their building blocks. Even though there are only 20 amino acids, there are more than a million different proteins, and each works in a unique way. Which of the following conclusions about a protein's function is best supported by this information? (4 points)
Group of answer choices
The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.
The amino acids reproduce in different ways, and this allows them to form many different proteins, which in turn directs the protein's function.
The shape of a protein determines what amino acids it is made of and what types of reactions it can be used for, which in turn affects the protein's function.
The shape of a protein dictates when a protein will break apart into amino acids, which in turn affects the protein's function.
Answer:
The amino acids combine in different ways to form proteins with different shapes, and this affects which molecules can bind to it, which in turn directs the protein's function.
Explanation:
There are many different combinations for amino acids to bind, and all of the different combinations have very different structures.
Additionally, the unique shapes of all proteins determine the exact function that they have.
These different shapes will also affect what molecules can bind to it.
What is the difference between smooth and rough endoplasmic reticulum (ER)?
The difference is that the the smooth (ER) is not bound by ribosomes. The rough endoplasmic reticulum on the other hand is bound by ribosomes.
Scientists have developed a new herbicide for dandelions that is specifically designed to prevent the conversion of stored energy. Which process does this herbicide affect?
Answer:
Ability to make ATP or the release of oxygen from chloroplasts.
Explanation:
Given that, ATP which is an acronym for Adenosine triphosphate, is where the energy is stored and produced in a plant and at the same time Herbicides affect plants in the area of photosynthesis specifically affecting the release of oxygen from chloroplasts, which in turn prevents the generation of energy required for plant growth.
Hence, in this case, the new herbicides affect the ability to make ATP in plants or the release of oxygen from chloroplasts.

Explanation:
What would happen to a plant cell if it placed in water?
Answer: It really depends on if the water solution is hypotonic, hypertonic, or isotonic. If it is hypotonic (water with less salt or other dissolvent in it than the cell), you can expect the cell to take in water and expand. If the water is isotonic (about the same amount of dissolvent in it as the cell) just about nothing will happen, or if the water is hypertonic (more dissolvent in the water than the cell) the water can seep out of the cell, and into the water.

M phase is known as mitotic phase and cell division occurs in this phase . The re-formation of the nuclear envelope during M-phase of the cell cycle takes place during telophase . The nuclear membrane which disappears during propahse reappears in the telophase . But before it is reformed the nucleus gets reorganised by Decondensation from chromosomes and reassembly of the nuclear lamina .MORE INFO :-______________
⚡ At telophase stage, nuclear membrane vesicles associate with the surface of individual chromosomes and fuse to reform the nuclear membranes, which partially enclose clusters of chromosomes before coalescing to reform the complete nuclear envelope .
