What process is the "copying" portion of protein synthesis? What is being copied? Why does it have to be copied?

Answers

The process of protein synthesis is known as translation. During this process, the mRNA is being copied into an orderly sequence of amino acids to produce a polypeptide.

During gene transcription, a fragment of DNA called gene is used as a template to generate a complementary messenger RNA (mRNA) sequence.

Afterward, this mRNA will be used as a template to create a protein by a process called translation.

The linear order of triplets of nucleotides or codons in mRNA will be used to add ordered amino acids to the growing polypeptide chain (i.e., the protein).

Describe the process of oxidation in terms of electrons AND energy.

Answers

Oxidation is described as the loss of electrons and energy by a molecule.

OXIDATION:Oxidation is a process whereby a molecule loses electrons (e-) or energy to become positively charged.

Oxidation changes the oxidation number of the molecule involved depending on the number of electrons lost.

Reduction is the opposite of oxidation, and it entails gain of electrons and energy by a molecule. Together, they are called oxidation-reduction or redox reaction.

Explanation:

Mary wanted to know if seeds needed water to start growing or if any kind of liquid would work. Mary set up several experiments to find out. She used radish seeds, paper towels, plastic bags, and different kinds of liquid in her experiment. Mary put three seeds into each bag. She then used 30mL of liquid to wet a paper towel and put a different paper towel in each bag. Mary put all of the bags on the same table next to a window so that they could each get the same amount of light. She waited three days and then checked her plants.

Answers

Answer:

independent variable: 30mL of liquid to wet a paper towel

dependent variable: how much the plants grow if at all.

control: they all received the same amount of light, that or the paper towels are the same.

experimental group: It's not stated that she did indeed use water, but there is a need for a control group, if so, then it's the other 2 groups that didn't use water, also because I can't think of anything else.

control group: The groups that used water rather than the other 2 plants.

How does 02 enter the mitochondria

Answers

How does oxygen enter the mitochondrial matrix? The electrons taken from NADH and FADH are passed to several other proteins in the inner mitochondrial membrane. Ultimately, they are passed to oxygen (O2). O2 becomes two molecules of water (H2O) after receiving four electrons. This is how oxygen is used by cell respiration.

Answers

In a cloud, water droplets condense onto one another, causing the droplets to get bigger and increase. When these droplets heavy enough, they fall to Earth as rain droplets. That is when we feel and see the rain. Water vapor turns into clouds when it cools and then condenses,or when it turns back into liquid water or ice.
