why old system of measurement isn't accepted nowadays ​

Answers

Answer 1
We can measure the length of an object using the units of measurement 'hand span,' 'forearm length,' or 'footstep.' Hand span, forearm length, and footstep, on the other hand, cannot be used as standard unit measurements because their length varies from person to person.

To conclude, the old system of measurement isn’t accepted anymore because it would not be accurate.

plants can change the main product of photosynthesis into other substances. Name two of these substances and describe the function of each​

Answers

Answer:

The products of photosynthesis are glucose and oxygen. Glucose is used by plants for energy and to make other substances like cellulose and starch. Oxygen is released as a byproduct/waste product. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

Explanation:

Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen. Many reactions occur, but the overall chemical reaction for photosynthesis is: Carbon Dioxide + Water + Light yields Glucose + Oxygen

As temperature rises from 25 degrees to 60 degrees, the material heat and its kinetic energy as the material goes through vaporization to become a gas.

What is a fatty acid?

A fatty acid is a long-chain carboxylic acid. It consists of a hydrocarbon chain with a carboxyl group at one end. Fatty acids are found in animal and plant fats, and they are an important part of the human diet.

Phenyl acetic acid is not a fatty acid because it does not have a long carbon chain. It is a short-chain carboxylic acid with only six carbon atoms. Short-chain carboxylic acids are not considered to be fatty acids.

What is the function of a chloroplast? A. Gamete production B. Cellular respiration C. Fermentation D. Photosynthesis ​

Answers

D photosynthesis is the function of a chloroplast

Answer:

So i had these notes from a couple of days ago and I’d like to help u out

Explanation:

Photosynthesis

Carbon dioxide enters through the leaf which contains small pours called stomata. The carbon dioxide then enters the cells of the leaf.

Inside the cell carbon dioxide diffuses into the chloroplasts. Where photosynthesis takes place

Chloroplasts use energy from sunlight to transform carbon dioxide and water into sugar and oxygen.

The light reactions

Inside chloroplasts there are these flat membranous sacs called thylakoids.

Thylakoids are the place were light energy is converted into chemical energy in the first phase of photosynthesis the light reactions.

Photosystems

Photosystems are large complexes of proteins and chlorophyll (capture light energy)

Electron transport chain

This chain connects the two photosystems.

Electron carrier

These shuttle (transport that is mainly between 2 things going back and forth) electrons from one photosystem to another

Photosystem

One of the photosystems are used to absorb energy which then excites the electrons that then enter the electron transport chain. These electrons are replaced with electrons stripped from water creating oxygen as a byproduct.

The electrons on the chain

The energised electrons are flowing down the electron transport chain releasing energy that is used to pump hydrogen ions

Hydrogen ions

An atom or molecule that has a net electrical charge due to the loss of one loss or one gained electron.

The electrons on the chain

As the hydrogen ions get pumped out they are then absorbed into the thylakoids

In the photosystem on the right  light energy excites electrons and this time the electrons are captured by an electron carrier molecule also known as NADPH

The high concentration of hydrogen ions inside the thylakoid powers ATP synthase producing ATPS the light reactions in the thylakoid have produced two products, ATP and NADPH.

Those two products then power the production of sugar in the Calvin cycle

THE CALVIN CYCLE (C3 Cycle)

The Calvin cycle takes place outside the thylakoids in the stroma (the thick fluid of the chloroplast).

At the beginning of the cycle

carbon dioxide molecules combine with molecules called rubp the resulting molecules go through a series of reactions  powered by ATP and NADPH from the light reactions sugar molecules known as g3ps are produced.

G3ps

Most of the g3ps molecules are rearranged back into rubp’s that begin the calving cycle again.

The important product

Then some of the left over g3ps is the remaining g3p sugar, some g3ps are used to build glucose which can then combine into starch or even cellulose

Bits of left over g3ps are also able to break down by cellular respiration, which uses oxygen in the plants own mitochondria, this generates ATPS that can power other work of the plant.

The left overs

Excess oxygen diffuses out of the leaf through the pores while more carbon dioxide goes into the leaf pores.

Suppose you have a beaker of sugar and a beaker of salt. They are unlabeled and the white crystals look identical. Your assignment is to identify each one. Tasting would make identification easy, but you should never taste anything in a science lab. Instead, you can use scientific knowledge and investigation to help you identify each substance.
Substance Formula Melting Point Conductivity
Table salt NaCl ? ?
Table sugar C12H22O11 ? ?

Examine the chemical formulas for salt and sugar given in the table. What do they tell you about what type of bonding is present in each compound?
A. Both molecules contain ionic bonds.
B. Both molecules contain covalent bonds.
C. NaCl contains a covalent bond, and C12H22O11 contains ionic bonds.
D. NaCl contains an ionic bond, and C12H22O11 contains covalent bonds.

Answers

D. NaCl contains an ionic bond and C12H22O11 contains covalent bonds.

As per the given scenario, NaCl contains an ionic bond, and [tex]C_1_2H_2_2O_1_1[/tex] contains covalent bonds. The correct option is D.

What is the difference between ionic and covalent bonding?

An atom can primarily participate in two types of bonding: covalent and ionic. The sharing of electrons between two or more atoms is referred to as covalent bonding.

When two or more ions come together and are held together by charge differences, ionic bonds form.

Covalent bonds are formed when two nonmetals come together, whereas ionic bonds are formed when a metal and a nonmetal come together.

Molecules formed by covalent bonds have a lower melting point than those formed by ionic bonds. The boiling point has the same relationship.

Electrons are basically involved in the formation of both ionic and covalent bonds.

NaCl is possess ionic bonding between sodium and chlorine ions, while table sugar have covalent bond.

Thus, the correct option is D.
