Comment on the folding of protein in vaccum
Answer:
Protein folding is a process by which a polypeptide chain folds to become a biologically active protein in its native 3D structure. ... The amino acids in the chain eventually interact with each other to form a well-defined, folded protein. The amino acid sequence of a protein determines its 3D structure.

Explanation:
if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm
What happens after Telophase?
&
36/86
>
C
Answer:
The chromosomes begin to uncoil, which makes them diffuse and less compact. Along with telophase, the cell undergoes a process called cytokinesis that divides the cytoplasm of the parental cell into two daughter cells.

Definition
high to low movement of molecules; uses transport protein; no energy required
a solution that has the same concentration of solute as the cells it surrounds
water-loving
a difference in the concentration of molecules from one location to another
structure that identifies the cell
having less solute molecules than the cytoplasm of a cell
allows certain molecules to pass through; keeps some molecules out
the amount of molecules in a specified area
use of vesicles to move large molecules out of the cell
the substance that is dissolved in a solution
movement of molecules from a low to high concentration; uses transport protein;
requires energy
movement of water from an area of high concentration to an area of low
concentration through a cell membrane; no energy required
mixture created when one substance is dissolved in another
movement of molecules from an area of high concentration to an area of low
concentration; no energy required
use of vesicles to move large molecules into the cell

Explanation:
For tetracycline , describe an experiment that you could
use to determine if a bacterial sample taken from a person was
resistant to your antibiotic. Be sure to describe all steps of the
experiment including your independent, dependent and control
variables.
Answer:
penicillin was the first antibiotic discovered. Alexander Fleming discovered it in 1928. It was used widely during World War II. However, the sulfonamides were the first antibiotic class used clinically (in the 1930's). The discovery of antibiotics revolutionized medicine by making once-deadly infections treatable. There are now hundreds of antibiotics, classified into several categories. These antibiotic classes include:

a radioactive element has a half-life of 3,000 years. if a sample of this element begins with a mass of 60 grams, how long would you have to wait for the mass to decrease to 15 grams
Answer:
N = 60 g
Half life : N/2 = 3000
N/4 = 15 g

how does shell color work to protect the egg from sunlight?
Answer:
Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight
Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.
The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell

What do producers dictate in
an ecosystem?
A. the size of the organisms
B. the age of the organisms
C. the amount of organisms
Answer:
C. The amount of organisms
Explanation:
Producers produce food from inorganic matter, this then makes food for other organisms in an ecosystem. The amount of producers dictates how much food is available, and by that how many organisms can be present.
