This type of molecule is the MOST common energy source for all cells and enters the cell by facilitated diffusion. The molecule is

Answers

Answer 1
Answer: The molecule ATP (Adenosine Triphosphate) 
Answer 2
Answer:

The answer is glucose. Ready energy for any type of cell is glucose. Other molecules may be used for energy, but they are broken down before being used as an energy source. DNA is not used for energy; proteins are used only when an organism is in starvation mode.

The Earth’s outer shell will get softer.


Volcanic activity will increase.


The continents will continue to move around.

Answers

Answer:

D or the last answer.

Explanation:

The continents will continue to move around because of the heat on the earth, that's why they will also continue to shift over time.

In 1967 a penicillin-resistant pneumonia, caused by Streptococcus pneumoniae and called pneumococcus, surfaced in a remote village in Papua, New Guinea. At about the same time American military personnel in southeast Asia were acquiring penicillin-resistant gonorrhea from prostitutes. By 1976, when the soldiers had come home, they brought the new strain of gonorrhea with them and physicians had to find new drugs to treat it.

In 1983 a hospital-acquired intestinal infection caused by the bacterium Enterococcus faecium joined the list of bacteria that could not be killed by penicillin.
Which of these BEST describes why certain bacteria have become resistant to penicillin?
A) The penicillin in the 1970's was much weaker that the penicillin used today, thus it was not as effective.
B) Penicillin was not effective in treating any bacterial diseases, so the doctors had to find new treatments.
C) These new bacterial strains came out of the jungles and forests already equipped to be penicillin-resistant.
D) Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.

I think B but i’m not for sure

Answer:

D. Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.

Explanation:

Researchers thought penicillin was the cure for all, and thus it became overused. Through natural selection, new, stronger strains of bacteria developed.

How do the atmospheric conditions near the beginning of Precambrian time contrast with the atmospheeic conditions that are present now? Which organism is largely responsible for this change?

Answers

Early pre-cambrian period the atmosphere consisted only of nitrogen and carbon dioxide without oxygen.

A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.

Autotrophs obtain energy by the process of photosynthesis. Any living organism need energy to survive and autotrophs are no different. Two types of autotrophs are present and they are Photoautotrophs and Chemoautotrophs. The Photoautotrophs rely on the energy produced during the process of photosynthesis and the Chemoautotrophs get their energy from most of the inorganic substances. Phtoautotrophs actually get their energy from the sunlight and then convert it into reusable form. In case of Chemoautotrophs ammonia is an important source of energy for them.

Answer:

The atmosphere has a much greater percentage of oxygen now that it did before. Cyanobacteria is the organism that is largely responsible for this change.
