Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?​

Answers

Answer:

Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.

Which type of curve?*

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.

Answers

First image shows a stationary organism whereas the second image indicates predator.

The first picture represents a leaf structure which is a part of plant and we know that plant is a stationary organism means it can't move from one place to another so that's why it is called a stationary organism.

While on the other hand, the second picture represents predator due to the presence of sharp teeth which helps the predators in catching and tearing of prey so we can conclude that first image shows a stationary organism whereas the second image indicates predator.

Read his draft andcomplete the task that follows.Although she came from humble beginnings in her native country of Poland, Marie Curie (born Marie Salomea Skodowska) was always eager to learn, and she was especially interested in science. Her family did not have much money, so she had to work several jobs in order to pay for college, eventually going on to study physics and math at the prestigious Sorbonne University in Paris, France. That is where she met and married a physics professor named Pierre Curie. The Curies enjoyed doing research together and became known for discovering two new elements. By the time of her death in 1934, Marie Curie's impressive accomplishments included: 1) the discovery of the elements radium and polonium; 2) invention of the first portable x-ray machines and portable radiology units; and 3) directorship of Curie Laboratory (named after her!) at the Radium Institute of the University of Paris.Choose the best hook that Trevor should use to begin his introductory paragraph:A.Marie Curie worked as a tutor and governess so that her older sister could study medicine in Paris.B.You really should learn more about Marie Curie, and I'm going to use the following essay to tell you all the great things you needto know about herC.Only one woman has ever won the Nobel Prize in both chemistry and physics, and her impact on science is closely felt even today!D.Marie Curie had to learn to speak French in order to study physics at the Sorbonne, A 1. 00-g sample of a metal x (that is known to form x2+ ions) was added to 0. 100 l of 0. 500 m h2so4.
