How is it possible that the reactants and products for both chemical equations have the same quantity of carbon, hydrogen, and oxygen atoms, yet the reactants and products are different molecules?

Answers

Answer:

Yes, this may be a little confusing when taking a first glance at the chemical equation.

Explanation:

You see, the whole process of balancing an equation is to make sure the reactants and products have the same amount of mass/atoms.

With that being said, the products to appear to be different after going through the chemical change. this is because of what was happening through that process. But, all of these atoms are still within the final product.

For example, if you take water in a container, one with a lid and one without a lid, then you heat up both containers of water, the container that has the lid open will seem like the water is gone, that the atoms are not the same. Actually, if we take a look at the closed container, all of that gas that was formed from the water still has the same amount of atoms contained in it. As for the open lid container, the atoms are all there, but some of them was just released into the air outside of the jar, making it seem like there is less.

The study of chemicals is called chemistry.

It is possible to have different chemical properties but the same number of elements present in the reactant and the product.

According to the law of mass of conservation of the mass. it states that the number of elements present in the reactant and the product will always remain the same.

Hence, according to this law, the mass and the quantity of the element are the same but the bonds and the arrangement of the elements are different which causes different chemical behavior.

Hence, it is possible.

Which best describes the importance of carbohydrates to organisms?
A. Carbohydrates provide an additional source for amino acids.
B.Carbohydrates provide an immediate energy source
C. Carbohydrates provide permanent storage for genetic information.
D.Carbohydrates provide storage for water molecules​

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ Carbohydrates \ provide \ an \ immediate \ energy \ source}}[/tex]

Explanation:

Carbohydrates are important because they provide the body with energy. It's essential to consume the correct amount of carbohydrates for your body, but make sure they are healthy (examples: whole grain, squash, sweet potatoes, beans)

Carbohydrates are easy for the body to break down. The body will digest these first into simple sugars, like glucose. The glucose is then used in cellular respiration to produce ATP or energy.

Therefore, carbohydrates can quickly provide energy for the body. The best answer choice is B.

Answer:

Carbohydrates provide energy to organisms.

Explanation:

I'm 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells

Vertebrates are complex animals, but they still share some characteristics with invertebrates. Mia volunteers at her city's aquarium for the summer. She likes observing the invertebrates. Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms?

Answers

Answer: Their body structure becomes increasingly more complex.

Explanation:

In the classification of living things, all animals belongs to Kingdom Animalia. This is contains two main groups namely:

--> invertebrates and

--> Vertebrates.

The vertebrates are complex animals which are characterized with the presence of a backbone.

The invertebrates are less complex animals with no backbone. The phyla that exists in this group includes: porifera, coelenterata, platyhelminthes, nematodes,annelida, mollusca, arthropoda,echinodermata and many among others.

Their body structure becomes increasingly more complex from the phylum porifera to the phylum echinodermata. The Sponges are simple aquatic invertebrates that have ASYMMETRICAL BODIES (this makes them to lack specialised tissues that could prevent them from moving about). While the echinodermata have RADIALLY SYMMETRICAL body with body parts arranged around a central mouth and anus. They have a unique system of water canals for transport inside the body and numerous tube feet moving about.

Explain what information about populations cannot be gathered when looking solely at population pyramid data.

Answers

Answer:

Hi there, so the population pyramid visualizes two variables which are sex and age but it doesn't tell us the actual number of population within a region it only collects the sex (female and males) and the ages (ranging from infant to elderly).

So the only thing that population pyramid data can't collect is the actual population in number.

Hope this helped :)  

The population pyramid, therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex (females and men) (ranging from infant to elderly).

What is the population?

As a result, the only thing the population pyramid data cannot measure is the size of the population.

Population pyramids do have certain restrictions, though. It is typically impossible to tell the relative contributions of various demographic processes on population age structure since they simply provide the size of each age-sex group in the population.

Therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex.

People spray pesticides on crops to kill insects that eat and destroy the crops. However, these insects are becoming resistant to the pesticides. Explain how this could happen.

Answers

The same way bacteria becomes resistant to antibiotics.

Mutations in their DNA.

When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.

What is pesticide resistance?

The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.

The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.

The use of the chemicals should be monitored. Only use when required with rotation.
