describe the earth in 3 sentences
Answer:
The earth is one of the many planets in our solar system and is the only known planet in our solar system that holds life. One of the reasons that planet earth can support live organisms is because it has the highest level of oxygen. The planet earth is also more protected from the sun, which keeps us warm, and overall holds the chemical ingredients to create life.

If one strand of a dna double helix has the sequence TATAGACGG what is the sequence of the other dna strand
Answer:
AUAUCUGCC
Explanation:
In DNA, the two strands are attached to each other by hydrogen bonding between the nitrogenous bases. The sequence of the other strand for the given strand: TATAGACGG is ATATCTGCC.
What is nucleotide base pairing?In DNA, two strands are present in the form of double helix which are held together in position by the help of hydrogen bonding. In DNA, four different nitrogenous bases are found. These are: Adenine, Guanine, Thymine, and Cytosine.
In DNA, each pyrimidine base pairs with a purine and vice versa. Adenine base pairs with thymine with the help of two hydrogen bonds and guanine base pairs with cytosine with the help of three hydrogen bonds.
So, each time an adenine comes opposite to a thymine and vice versa. Similarly, a guanine comes opposite to a cytosine and vice versa. This can be used to derive the sequence of the other strand for the given strand of DNA.

Translate the word phrase into an algebraic equation: the quotient of 24 and 2 is equal to 12.
Answer:
24/2 = 12
Explanation:
(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)
To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:
= : "equal to", "is", "equivalent to", etc.
> : "greater than"
< : "less than"
>= : "greater than or equal to", "at least"
<= : "less than or equal to", "at most"
We also have to know basic math operations:
a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.
a - b : "a minus b", "b less than a", "b subtracted from a", etc.
a * b : "a multiplied by b", "a times b", "the product of a and b", etc.
a / b : "the quotient of a and b", "a divided by b", etc.
There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.
So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,
24/2 = 12.

phospholipid bilayer
Answer:
Although the basic structure of biological membranes is provided by the lipid bilayer, membrane proteins perform most of the specific functions of membranes. It is the proteins, therefore, that give each type of membrane in the cell its characteristic functional properties. Accordingly, the amounts and types of proteins in a membrane are highly variable. In the myelin membrane, which serves mainly as electrical insulation for nerve cell axons, less than 25% of the membrane mass is protein. By contrast, in the membranes involved in ATP production (such as the internal membranes of mitochondria and chloroplasts), approximately 75% is protein. A typical plasma membrane is somewhere in between, with protein accounting for about 50% of its mass.
Because lipid molecules are small compared with protein molecules, there are always many more lipid molecules than protein molecules in membranes—about 50 lipid molecules for each protein molecule in a membrane that is 50% protein by mass. Like membrane lipids, membrane proteins often have oligosaccharide chains attached to them that face the cell exterior. Thus, the surface that the cell presents to the exterior is rich in carbohydrate, which forms a cell coat, as we discuss later.

**Chose one right answer PLEASE**
Which variable is missing from the experiment?
A. Independent variable; plants should be watered at different times of the day
B. Controlled variable: experiment should use the same types of plants
C. Dependent variable; the amount of sunlight should change daily
D. Controlled variable: experiment should use the same amount of water
Controlled variable: experiment should use the same types of plants. Thus option B is correct.
What are the types of variables in experiment ?Variables are the measure, manipulate and control in research. For example person's eye color, its value can change from brown to blue depend on different factors.
An independent variable is a singular characteristic, Age is an example of an independent variable.
A dependent variable relies on other variable and can be changed by other components. For example a grade on an exam is a dependent variable mainly depend on Independent variables.
A Controlled variable remain constant and no effect on other variables. It is used to prevent bias in an experiment.
An intervening variable or mediator variable used to explain a cause or connection between dependent and independent variables.
Thus option B is correct.
