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:

Which statement correctly describes the relationship between elements and compounds?
O A. Compounds contain fixed ratios of different elements.
B. Elements contain fixed ratios of different compounds.
C. Compounds contain variable ratios of different elements.
D. Elements contain variable ratios of different compounds.
Answer:
A. Compounds contain fixed ratios of different elements.
Explanation:
Water always has this 2:1 ratio of hydrogen to oxygen. Like water, all compounds consist of a fixed ratio of elements. It doesn't matter how much or how little of a compound there is. It always has the same composition.
Every compound has fixed ratios of different elements. The correct option is A.
What is an element?A substance that could not be converted into various components by any non-nuclear chemical process is referred to as an element.
Every compound has fixed ratios of different elements.
Thus, the correct option is A.

Who is the first discovered plants were made of cells?
Answer: PLEASE MARK ME AS BRAINLIST
Explanation:
The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.
the German botanist Schleiden proposed that all plants are made up of plant cells. Thank you.

Explanation:
The measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane is called...
A. Osmolarity
B. Equilibrium
C. Homeostasis
D. Tonicty
The osmotic gradient, which is the concentration difference between two solutions on either side of a semipermeable membrane, is used to determine a particle's concentration in a solution. Thus, Option A is correct.
What is osmolarity of a solution?Osmolarity, which is determined by the number of osmosis of a solute per liter of solution, is a gauge of solute concentration.
According to their relative osmolarity, solutions can be broadly characterized as hypertonic, hypotonic, or isotonic.
Osmolarity is important because cells cannot survive if their environment's osmolarity is significantly different from their own.
From a lower osmolarity to a greater osmolarity, water flows over a membrane. It switches from the diluted to the concentrated side, to put it another way.
Therefore, osmolarity measurement of the pressure gradient of two solutions that are separated by a selectively permeable membrane.

Describe the functions of proteins in cell membrane.
Answer:
Membrane proteins can function as enzymes to speed up chemical reactions, act as receptors for specific molecules, or transport materials across the cell membrane. Carbohydrates, or sugars, are sometimes found attached to proteins or lipids on the outside of a cell membrane.
Sample Response: When there is less rainfall, land,
which is part of the geosphere, becomes dry. When there
is not enough water, plants will not get the nutrients they
need from the soil and animals will not get enough water,
and they will die. Both plants and animals are part of the
biosphere. Less precipitation would also mean less water
in lakes and groundwater, parts of the hydrosphere, and
less evaporation. The atmosphere may also be affected
due to less water vapor.

that apply.
Droughts can cause the geosphere to be very dry.

When there is less or no rain than expected it will lead to draughts.
Draughts:When there is less rainfall all the parts and organisms of the earth get affected. Water is an essential component of life. Less rainfall leads to the scarcity of water on the earth.
Farmers will not get enough amount of water for farming, groundwater levels also get affected. Plant and animal life also gets affected, and this affects the survival of organisms. Draughts can also affect the amount of water in the hydrosphere.
Food, fruits, and vegetables also get reduced because of less amount of rainfall. Therefore good rain is essential for the lives of the plants and animals. This is important for the survival and the good life of the organism.
Therefore, When there is less or no rain than expected it will lead to draughts.

What's wrong with this ecological pyramid?
Answer:
The sun has an arrow leading to the decomposer, the sun should be at the bottom of the pyramid
Explanation:
The sun is the ultimate source of energy that provides energy to the producers. The producers use the light energy to synthesize the chemical compound. The energy from the producers is transferred to the primary consumers and their energy is transferred to the next levels. The sun cannot be decomposed by decomposer so the arrow from the sun leading towards the decomposer is not right.

7,351 round to nearest hundred
Answer:
7 400
Explanation:
7, 351
7 is the thousands
3 is the hundreds
5 is the tens
1 is the unit
to round of to the nearest hundred look at both the hundreds value and the tens value.
since the tens value is 5 , this means the hundreds value increases by 1.
therefore 3 turns into 4
7351 to the nearest hundred is 7400

Atoms connected by covalent bonds share a ionic compounds. b pairs of electrons. c carbon and oxygen. d hydrogen ions.
Answer:
B
Explanation:
Atoms connected by covalent bonds share electrons. Therefore, the correct answer is option B.
Extremely high ionization energies prevent some elements from accepting electrons, and extremely low electron affinities prevent some elements from accepting them. These elements' atoms frequently share their electrons with those of other elements or with other atoms of the same element in order for both atoms to achieve stability by forming an octet configuration in their respective valence shells. Covalent bonds are those associations that involve sharing electron pairs between entities of different or similar kinds.
Therefore, a pair of electrons is shared between atoms connected by a covalent bond. The correct answer is option b i.e. pairs of electrons.
