Which action would most likely increase the rate of an enzyme-controlled reaction during an experiment on human enzymes? 1 point raising the temperature from 20C to body temperature decreasing the intensity of light raising the temperature from 50C to 100C decreasing the amount of enzyme
Answer:
Raising the temperature from 20c to body temperature
Explanation:
The increase in temperature will give the particles more thermo energy therefore it will increase the rate of an enzyme-controlled reaction

Which statement best describes the basic process of photosynthesis?
a. Chemical energy is transformed into light energy and oxygen is released.
b. Light energy is transformed into chemical energy and oxygen is released.
c. Light energy is transformed into chemical energy and carbon dioxide is released.
d. Chemical energy is transformed into light energy and carbon dioxide is released.
Answer:
b. Light energy is transformed into chemical energy and oxygen is released.
Explanation:
Photosynthesis is a process in which light energy from sun is transformed into chemical energy and oxygen is released. Therefore, option (B) is correct.
What is Photosynthesis ?The chloroplast organelle of plant cells is where the process of photosynthesis takes place. The thylakoid membrane of the chloroplast is where the normal light response of photosynthesis takes place. Water and carbon dioxide, two of the main reactants, take part in the process. In the process of the reaction, the water is oxidized, producing oxygen as a byproduct. Carbon dioxide is reduced.
In essence, the chloroplast's chlorophyll pigment transports the electron and hydrogen from water to the acceptor known as NADP+ when it absorbs light.
Hence, light energy is transformed. Option (C) is correct.

Explain the process of DNA Replication in details
When will DNA replication occur?
(They don’t have to be too long just long kinda lol)
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).

Both mixtures and compounds are made of two or more different substances mixed together. So
which of the following is an accurate statement about the difference between the two?
a- generally speaking compounds are easier to separate than mixtures
b- compounds are mixed physically but not chemically
c- a mixture is two or more substances mixed physically but not chemically
d- mixtures are pure substances while compounds are not
Answer:
c- a mixture is two or more substances mixed physically but not chemically
Explanation:
In chemistry, a mixture and a compound is made up of two or more different substances that combines together, however, the difference between the two is in the way the combination occurs. Compounds are pure substances formed as a result of the chemical combination of two or more elements. The atoms of the elements in a compound are chemically bonded together in such a way that they cannot be separated.
On the other hand, mixtures are substances composed of two or more substances of different properties that are combined physically i.e. there is no chemical bonding between them, hence, components of a mixture can easily be separated using physical methods like boiling, melting, etc dependent on the individual properties of the components.

Why are endocytosis and exocytosis kinds of active transport?
Explanation: During endocytosis (endo means inside) a cell will use its cell membrane to engulf an object which is outside of the cell. This process takes effort by the cell, so it needs to use energy (ATP!) The process which is the reverse of endocytosis is exocytosis (exo means outside - think exit).
Answer:
Endocytosis and exocytosis are active transport mechanisms in which large molecules enter and leave the cell inside vesicles. In endocytosis, a substance or particle from outside the cell is engulfed by the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane.

atoms?
molecules?
cells?
Answer:
presence of cells
Explanation:
All living things are composed of cells. A cell can be defined as a complex biological arrangement that has all the structures and materials required for life. Cells carry out specialized functions such as, for example, metabolic functions to convert nutrients from food into energy (ATP), and reproduce by mitosis and/or meiosis. Thus, the cell is known to be the basic unit of life.

The chemistry café cook has a loaf which had 33 slices and a package of cheese that has 15 slices. he is making sandwiches that have 2 pieces of both breed and cheese. how many sandwiches can he make?
Answer:
Explanation:
so
2 breads + 2 cheeses ⇒ 1 sandwich
if we use two slices of bread each time how many sandwich can we make with 33 slices
33/2 =16.5 sandwiches
if we use two pieces of cheese in each sandwiches how many sandwiches can we make with 15 slices ?
15/2 =7.5 sandwiches
the cheese her will run out first and we would have excess bread
so we would only be able to make 7.5 sandwiches without running out of ant ingredient :)
From the calculations, we can see that the producer can make about 12 sandwiches.
Bread and cheeseIn the question, we are told that there are;
a loaf which had 33 slicesa package of cheese that has 15 slicesWe also know from the question that he is making sandwiches that have 2 pieces of both breed and cheese.
Hence; total number of bread and chese = 33 + 15. Each bread must contain two pieces of each of the bread and chees making a total of four pieces. He can therefore make; 33 + 15/4 = 12 sandwiches.
