Sheila bought a hamster in a small pet shop. To feed it properly, she
needs to know its weight. If the hamster has a mass of 190.0 g, what is
its weight?
Answer:
190*10=1900N
Explanation:
it is mentioned that its mass is 190g. So the weight must be equal to the product of mass and acceleration due to gravity.
taking acceleration due to gravity 10m/s2 the answer must be 1900N
But the accurate vale is 9.8m/s2.
also let me know if the answer was correct.

There are 3 main categories of environmental problems that have come about because of the population growth. What are they and explain how the growth of the population has brought about each one?
Answer:
i)declination of resources
ii) air, water and land pollution
iii) global warming
Explanation:
As we all know that population is increasing day by day, all the country of the world are facing rapid population growth.we are facing many problems, the population growth is increasing day by day, the more the population, the more resources we need due to this, the resources is decreasing day by day, we need more resources as there is more population, the increasing population makes more pollution due to this global warming is increasing. We know that there is no more more resources in our world if the resources is finished in this day the future generation will not be able to survive and will not be able to use such resources.we should prevent such resources for future generation also the future generation should get the chance to use such resources .the pollution is increasing day by day .we should control it .the main thing is that we should control the rapid population growth population growth should be controlled due to this global warming is increasing which is very dangerous leading to the declination of ozone layer due to which the harmful rays of sun may enter the earth which may cause various problems in us and cause various diseases due to which we may die.the main thing is that we should stop the population growth, we should conduct public awareness programmes and many more programmes to educate people. Population growth also creates deforestation as the number of people are increasing day by day they need more place to live ,they need more Land due to this they cut down the trees of forest and used to make houses there due to which deforestation takes place. we all know that deforestation is the process of cutting down trees. so the tree should not be cut down as it is the source of oxygen for all creatures living in this whole world and the main thing is that we should provide education to the children and the youth and many more. if we are educated we can stop such population growth. so the main thing is that we should stop population growth by giving education. Education is the only one way to stop such population growth.
what are the effects of changes in one of earth four spheres on each of the other spheres?
Answer:
An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction. Interactions also occur among the spheres.

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

DNA and Rna are macromolecules made up of what?
Answer:
Nucleotides
Explanation:
"These macromolecules consist of a large number of linked nucleotides, each composed of a sugar, a phosphate, and a base."
Hope this helps:
DNA, RNA, and the Flow of Genetic Information
https://www.ncbi.nlm.nih.gov/books/NBK21171/
DNA and RNA are macromolecules made up of units called nucleotides.
What are nucleotides?A nucleotide is the most fundamental element of nucleic acids (RNA and DNA). A sugar molecule (ribose in RNA or deoxyribose in DNA) is bonded to a phosphate group and a nitrogen base to form a nucleotide. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the bases that make up DNA. The base uracil (U) replaces for thymine in RNA. Long chains of nucleotides make up DNA and RNA molecules, which are polymers.
hence nucleic acids like DNA and RNA are made up of nucleotides
