What causes a substance’s identity to change during a chemical change?

Answers

Answer 1
Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties. ... One good example of a chemical change is burning a candle.

During photosynthesis, from where does the energy for converting carbon dioxide into sugar come?

Answers

Answer:

Solar energy is converted to chemical energy in the photosynthesis process, which converts water and carbon dioxide to glucose.

Explanation:

Hope this helps!

During photosynthesis, the energy for converting carbon dioxide into sugar comes from the sun, it is solar energy.

What is photosynthesis?

Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.

Photosynthesis in plants uses the green pigment chlorophyll and produces oxygen as a byproduct. Plants use their leaves to trap light energy during photosynthesis.

Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to generate other compounds such as cellulose and starch.

Therefore, the energy used to convert carbon dioxide into sugar comes from the sun during photosynthesis; this is known as solar energy.

How is glucose stored in skeletal muscle? Why cannot glucose be released from skeletal muscles to maintain blood glucose concentration?

Answers

Answer:

In skeletal muscles with low glycogen, glucose will be stored as muscles glycogen.

Skeletal muscles are unable to release glucose because muscles lack glucose 6 phosphatase. Also, muscles glycogen is mainly a local energy substrate for exercise, rather than an energy source to maintain glucose concentration during fasting.

how will you select and grow a resistant strain of e. coli in this experiment?

Answers

Streptomycin treatment is used in medicine. It s growth is to expose a sample of E.coli to streptomycin by innoculating it into a streptomycin positive plate. any colonies that grow will carry a mutation for resistance.

Streptomycin treatment is known to boast or increase the growth of E. coli by nitrate respiration.

Streptomycin is simply regarded as an antibiotic which is often used to treat moderate to severe tuberculosis, pneumonia, E. coli, etc.

See full question below

How will you select and grow a resistant strain of E.coli in this experiment?multiple choice:

(1). expose a sample of E.coli to streptomycin by innoculating it into a streptomycin positive plate. any colonies that grow will carry a mutation for resistance,

(2.) expose a sample of E.coli to sterptomycin by innoculating it into a streptomycin negative plate, any colonies that grow will carry a mutation for resistance,

(3.) samples of bacteria are taken from the culture and observed under a microscope for signs of susceptibility or resistance. those that are resistant are separated and plated.

(4.) a culture of E.coli will be mixed with streptomycin so that the antibiotic can alter the genetic composition of the bacteria

which mechanism of action is being described when an antibiotic drug causes the destruction of bacterial cell walls

Answers

The mechanism of action described when an antibiotic drug causes the destruction of bacterial cell walls is NONSELECTIVE INTERACTION. These drugs do not interact with specific molecules.

Nonselective drugs are involved in nonselective interactions, i.e., they act on a variety of receptors and/or enzymes.

Nonselective drugs can target different cellular structures (e.g., bacterial cell walls) and/or metabolic processes.

For example, Phenocybenzamine is a nonselective drug that can affect different receptors, which is used for the treatment of high blood pressure and sweating associated with pheochromocytoma.

Conversely, enzymes are biological catalysts that speed up chemical reactions by selectively interacting with specific ligands (i.e., substrates).

In eukaryotic mRNA, the parts that remain after processing and are translated into amino acid sequences are called the _____.

Answers

Answer:

Exons.

Explanation:

In mRNA maturation and processing, a complex called a splicesome essentially "cuts out", if you will, non-coding parts of the DNA sequence to be translated. The parts that are cut out are called "introns", and the parts that are left over that code for a protein sequence, are called "exons". Careful with the terminology. It seems counterintuitive that exons are the ones that stay (exon = exit? NO.) and introns (in, as in, stays in? NO.) are the ones that are cut out of the mature mRNA. Perhaps you can remember that the terms seem to be the opposite, that's how I remember it. Alright, good luck with all of this.

Which of the following best describes how you know the matter that makes up the sequoia tree comes from your answer in the previous question.


A. All the energy comes from the sun, so it would make sense that any matter we get would also come ultimately from the sun. Without the sun, no photosynthesis would happen


B. Water and carbon dioxide supply us with the matter and they are the inputs for photosynthesis, and everything starts with photosynthesis


C. Our bodies are made of over 90% water, so we essentially are water which is an input for photosynthesis


D. We are made of carbon-based molecules and that carbon needs to come from somewhere, so the carbon comes from the glucose we eat which came from the carbon dioxide.


E. Glucose is eaten by us which is then used to build oxygen and carbon dioxide molecules that will get released back into the air. We are able to make air which is an example of matter/mass in our biosphere
